Establishing cause of death in HSCT recipients
With a new study, researchers hope to establish definitions for specific causes of death in patients who undergo allogeneic hematopoietic stem cell transplant (HSCT).
The group noted that scientists conducting clinical trials commonly use committees to review and define endpoints.
However, investigators conducting genome-wide association studies rarely do, relying instead on center-reported outcomes, which are variable.
“It is important that we accurately define outcomes in these types of genomic studies as precisely as possible,” said Lara Sucheston-Campbell, PhD, of Roswell Park Cancer Institute in Buffalo, New York.
To that end, she and her colleagues convened a consensus panel to review specific causes of death in HSCT recipients. The panel evaluated outcome data for 1484 patients who had been treated for acute leukemia or myelodysplasia at 1 of 11 US transplant centers and died within a year of undergoing HSCT.
Dr Sucheston-Campbell and her colleagues reported the results of this evaluation in Biology of Blood and Marrow Transplantation.
In the cases where the transplant center reported disease-related mortality, the researchers found almost perfect agreement between the consensus panel and the transplant center, in terms of how those deaths were classified. The panel agreed with more than 99% of deaths that were reported as disease-related.
There was less agreement for transplant-related mortality, however. The panel agreed with about 80% of deaths reported to be transplant-related.
And the level of agreement/discordance varied depending on the specific cause of death. For example, the panel agreed with transplant centers on most of the deaths that were reportedly caused by graft-vs-host disease.
But the panel reclassified many of the deaths that reportedly resulted from organ failure, saying these deaths should be considered disease-related, a result of graft-vs-host disease, infection-related, or due to “other” causes.
These results indicate that transplant-related mortality needs to be better defined, the researchers said. They believe this study provides a mechanism for prioritizing those HSCT cases that should be reviewed.
“We need to make sure that patients who experienced similar clinical events after a transplant were consistently defined regardless of where they were treated,” said study author Theresa Hahn, PhD, also of Roswell Park Cancer Center.
“This is a difficult topic to consider, but we can’t make progress to improve transplant outcomes without these discussions.”

Harnessing immune defense to treat Candida infection
An upset in the body’s natural balance of gut bacteria that may lead to life-threatening bloodstream infections can be reversed by enhancing an
immune response, according to research published in Nature Medicine.
Researchers found that a transcription factor known as HIF-1α works with LL-37, a naturally occurring antibiotic, to kill the infection-causing fungi Candida albicans.
And this response can be enhanced with a drug called L-mimosine.
The researchers noted that Candida albicans can be lethal if it invades the bloodstream from the gut. And stem cell transplant recipients and immunosuppressed cancer patients have a high risk for this type of infection.
“For a cancer patient with a Candida bloodstream infection, the fatality rate is about 30%, [and] Candida is the number 1 fungal pathogen,” said study author Andrew Koh, MD, of the University of Texas Southwestern Medical Center in Dallas.
With that in mind, he and his colleagues set out to determine how the body’s natural immune defense system might be enhanced to fight a Candida infection. By studying how mice infected with Candida responded in different scenarios, the team found their answer.
“The commensal bacteria stimulate gut tissue to make a transcription factor and a natural antibiotic, which then kills the Candida fungus,” Dr Koh explained.
“When we gave the mice a pharmacologic agent called L-mimosine that stimulates the transcription factor, the agent knocked down Candida 100-fold, which translated into a 50% reduction in mortality from invasive Candida infection.”
Specifically, the researchers found that enhancing the transcription factor HIF-1α with L-mimosine led to increased production of the natural antibiotic peptide LL-37, which, in turn, killed the fungi. L-mimosine is a natural product derived from seeds of the koa haole tree that is known to boost HIF-1α activity.
The study also suggested that certain gut bacteria—Clostridial Firmicutes and Bacteroidetes—may be important in producing short-chain fatty acids that help fight infection.
The researchers said more work is needed to pinpoint the optimal method of inducing the body’s gut defense system, whether through use of an agent like L-mimosine or by administering short-chain fatty acids such as vinegar.
“Can we modulate the gut system to maintain balance so that it never gets to the point of pathogens invading the bloodstream?” Dr Koh asked. “Boosting [gastrointestinal] mucosal immune effectors to reduce fungal burden may be the key to tipping the balance back toward normal and preventing invasive fungal disease.”

ASCO: Adjuvant denosumab halves fracture risk for breast cancer patients on AIs
CHICAGO – Adjuvant denosumab is efficacious and safe for reducing fracture risk among women taking aromatase inhibitors (AIs) as part of their treatment for early breast cancer, finds the Austrian Breast & Colorectal Cancer Study Group’s study 18 (ABCSG-18).
Compared with peers randomized to placebo in the phase III trial, women randomized to the antiresorptive monoclonal antibody at the dose typically used to treat osteoporosis were half as likely to experience a first clinical fracture, first author Dr. Michael Gnant reported at the annual meeting of the American Society of Clinical Oncology. The benefit was similar whether women had normal bone mineral density at baseline or already had osteopenia.
Patients in the denosumab group did not have a significantly higher rate of adverse events, including the much-feared complication of osteonecrosis of the jaw.
“The actual fracture risk of postmenopausal breast cancer patients on AIs is substantial and may have been underestimated until today,” commented Dr. Gnant, professor of surgery at the Medical University of Vienna. “In these patients with only a modest risk of disease recurrence, adjuvant denosumab significantly reduced the bone side effects of AI treatment. We therefore believe that denosumab 60 mg every 6 months should be considered for clinical practice.”
“Today, several clinical practice guidelines advocate the use of bisphosphonates for breast cancer patients receiving AIs, however, only if they are at high risk for fractures,” he further noted. However, “patients with normal baseline bone mineral density showed a similar fracture risk but also similar benefit from denosumab as compared to patients with baseline T scores below –1, indicating that DEXA scans may be an insufficient way to assess the individual patient’s fracture risk. In view of the benefits in this particular patient subgroup, we may have to rediscuss our current clinical practice guidelines.”
Invited discussant Dr. Robert E. Coleman of the University of Sheffield and Weston Park Hospital in England, said, “It’s very important to dissect out fractures related to subsequent recurrence from fractures due to poor bone health.” Most of the reduction in fracture risk in ABCSG-18 appeared to be because of prevention of fractures before any recurrence, whereas most of that in the AZURE trial (Adjuvant Zoledronic Acid to Reduce Recurrence) of an adjuvant bisphosphonate, another type of antiresorptive agent, appeared to be because of prevention of fractures from bone metastases. “So I think we are seeing something very different with denosumab to what we’ve seen to date with a bisphosphonate,” he said.
“As oncologists, we are somewhat wedded to measuring bone mineral density as the reason for giving bone-targeted therapy to protect [against] bone loss, but there are much better ways of predicting fracture with online algorithms such as FRAX [Fracture Risk Assessment Tool] and others,” Dr. Coleman further commented. “And bone mineral density is a pretty poor predictor of fracture, so it’s perhaps not surprising that the risk reductions were fairly similar” across bone mineral density subgroups.
During a question and answer period, session attendee Dr. Toru Watanabe, Hamamatsu (Japan) Oncology Center, said, “It is really clear that the osteoporosis-related fracture is prevented by denosumab at the dose usually used for the treatment of osteoporosis. That part is very clear. My question is, the same dose is being tested for modifying overall survival or progression-free survival. Don’t you think it’s necessary to conduct some kind of dose-finding trial?”
Two studies are addressing the impact of denosumab on breast cancer outcomes, according to Dr. Gnant: the investigators’ ABCSG-18 study and the Study of Denosumab as Adjuvant Treatment for Women With High-Risk Early Breast Cancer Receiving Neoadjuvant or Adjuvant Therapy (D-CARE), which is using a higher initial dose and tapering after 1 year. “So we will have that indirect comparison at least. My personal expectation would be that there is a trade-off potentially between efficacy and tolerability,” he commented.
The 3,425 postmenopausal breast cancer patients in ABCSG-18 were randomized evenly to receive 60 mg of denosumab or placebo every 6 months. Denosumab is approved by the Food and Drug Administration for the prevention and treatment of fractures due to bone metastases (brand name Xgeva) and osteoporosis after menopause (brand name Prolia), as well as other indications. The study used the dose for postmenopausal osteoporosis, which is much lower than that typically used for bone metastases (120 mg every 4 weeks), Dr. Gnant noted.
Main results showed that denosumab was highly efficacious in reducing the risk of first clinical fractures, meaning those that were clinically evident and causing symptoms (hazard ratio, 0.50; P less than .0001), according to data presented at the meeting and simultaneously published (Lancet 2015 May 31).
The estimated 6-year fracture rate was about 10% in the denosumab group and 20% in the placebo group. “Please note that the frequency of clinical fractures reported in this trial that is focusing on bone health is markedly higher than fracture rates reported in previous large AI trials. Obviously, we had a tendency to underreport them in those trials,” Dr. Gnant commented. “The true magnitude of the problem in clinical practice is likely reflected in the placebo group … with approximately one out of five patients experiencing a new clinical fracture within 5-6 years of adjuvant AI treatment.”
Benefit was similar across numerous patient subgroups studied, including the subgroups of women who had a baseline bone mineral density T-score of less than –1 and women who had a baseline bone mineral density T-score of –1 or greater.
Additionally, the denosumab group had improvements from baseline in bone mineral density of the lumbar spine, total hip, and femoral neck, whereas the placebo group had worsening at all sites (P less than .0001 between groups for each site). And at 36 months, the denosumab group had significantly lower risks of both new vertebral fractures and new or worsening vertebral fractures.
“Adjuvant denosumab at this dose and schedule is safe,” Dr. Gnant maintained. The two groups had similar rates of various adverse events, with musculoskeletal disorders and vascular disorders (including hot flashes) predominating. “This means that we are in essence reporting the side effects of the underlying adjuvant AI treatment,” he noted.
There were 31 cases of dental issues, but none met diagnostic criteria for osteonecrosis of the jaw. “We can safely say that at this dose of denosumab, 60 mg twice yearly, ONJ is not an issue,” Dr. Gnant commented. Additionally, none of the women experienced atypical fractures.
Dr. Gnant disclosed employment of an immediate family member with Sandoz; receipt of honoraria from Amgen, AstraZeneca, GlaxoSmithKline, NanoString Technologies, Novartis, and Roche Pharma AG; a consulting or advisory role with Accelsiors, AstraZeneca, and Novartis; and receipt of research funding from GlaxoSmithKline, Novartis, Pfizer, Roche Pharma AG, Sanofi, and Smiths Medical. The trial was sponsored by Amgen.

Coding for “Incident-to” Services
Services that physicians bill to Medicare but do not perform themselves are called “incident-to” services. These services usually are performed by nonphysician medical providers under close physician supervision. The authorization to bill for these incident-to services derives from the Social Security Act,1 which provides for Medicare coverage of services and supplies offered incident to the professional services of a physician. The underlying logic is that incident-to services are delivered as a necessary but incidental part of the physician’s professional services during diagnosis or treatment.
Eligibility Criteria
One key qualification for incident-to services is direct supervision of a nonphysician provider by a physician. When services are delivered in an office setting (place of service 11), the physician must be present in the office and immediately available to offer direction to nonphysician providers. Some states do include telecommunication in their definition of direct supervision, wherein the physician is accessible by telephone or some similar medium.
Another element necessary in the criteria for incident-to services is that initial care must be personally provided by the physician who also writes orders for ongoing care. In general, incident-to services include ongoing physician involvement in the provision of care. Importantly, the physician who first saw a patient, initiated service, or ordered a test is not the only one who can supervise subsequent incident-to visits with a nonphysician provider. In office settings where several physicians are responsible for overseeing a nonphysician provider, any of these physicians who are in clinic at the time can act as the supervising physician. In such cases, each of the other physicians should be listed in appropriate documentation as substitute physicians for the nonphysician provider.
The Centers for Medicare & Medicaid Services recognize a variety of nonphysician providers, but in dermatology these providers typically include physician assistants, certified registered nurse practitioners, or clinical nurse specialists. When services offered by these nonphysician providers are reported as incident-to services, Medicare reimburses them at 100% of the physician fee schedule; conversely, a non–incident-to service reported under a nonphysician provider’s National Provider Identifier (NPI) number is reimbursed at 85%. Only approved mid-level nonphysician providers may bill evaluation and management services with codes above 99211 under incident-to guidelines. Even then, the services delivered must be appropriate for the given nonphysician provider based on training and licensure.
Not every type of visit is eligible for coding as an incident-to service. For instance, it is not appropriate to code new patient visits or new services provided to existing patients as incident-to services. Similarly, visits with established patients that address new diagnoses or problems cannot be considered incident-to services. The only visits or services that may potentially be classified as incident to are those that address existing problems in established patients with an established care plan.
When an established patient presents with a new problem, there are at least 2 coding approaches that may be appropriate. First, the physician could choose to see the patient and code the visit as a standard physician visit under the physician’s own NPI number. Alternatively, if the supervising physician in the practice is not available to see the patient, the nonphysician provider could code the entire service, including new and old problems, under his/her own NPI number as a non–incident-to service.
Regulations by State and Payer
State regulations and rules promulgated by specific payers also must be considered to ensure incident-to coding is proper. Each state may have guidelines that define the scope of practice of particular nonphysician providers, including what services can or cannot be coded as incident-to services. Additionally, states typically regulate the number of nonphysician providers that a physician can supervise; by extension, no more than this number of nonphysician providers could bill incident-to services under a given physician’s NPI number. Private payers may have comparable rules, and specific Medicare guidelines apply to Medicare patients. When there is ambiguity regarding incident-to coding, it may be prudent to check with major payers regarding relevant guidelines. It also may be helpful to confirm when supervision via telecommunication is acceptable.
Billing Tips
Common sense also can guide appropriate use of incident-to coding. Although occasional coding errors are likely unavoidable, periodic review of billing patterns will keep these errors to a minimum. For instance, if a nonphysician provider is the only provider of any type seeing patients in the office during particular days of the week, then incident-to coding would be unlikely. In another example, the number of nonphysician providers working with a given dermatologist and billing incident-to services should not exceed the number of nonphysician providers allowed per physician in that state. An interesting twist is the case in which a dermatologist is working in an ambulatory surgery center while a nonphysician provider is seeing patients in an adjacent office suite. Even when the 2 sites of service are physically contiguous, the physician in the surgery center generally is not deemed to be in office and is not able to supervise the nonphysician provider, unless telecommunication is allowed.
Final Thoughts
Attention to correct coding for incident-to services is particularly salient, as the Office of Inspector General (OIG) for the US Department of Health & Human Services has expressed concern that these services may be routinely coded incorrectly. Specifically, the OIG work plan for the 2013 fiscal year stated, “We will review physician billing for ‘incident-to’ services to determine whether payment for such services had a higher error rate than that for non–incident-to services.” The same report also cited a 2009 OIG review that found that “unqualified nonphysicians performed 21 percent of the services that physicians did not personally perform.”2 In short, coding for incident-to services is under scrutiny, and it may be useful for dermatologists to review their internal policies regarding incident-to services.

Practice Points
- Direct supervision of a nonphysician provider by a physician must be demonstrated for incident-to services. Not every type of visit is eligible for incident-to billing.
- Only management of established problems on established patients by nonphysician providers may qualify as incident-to services.
- Refer to state and payer regulations and rules for proper incident-to coding.
Prevalence and Impact of Health-Related Internet and Smartphone Use Among Dermatology Patients
Patients increasingly use the Internet and/or smartphone applications (apps) to seek health information and track personal health data,1,2 typically in the spirit of being a more educated consumer. However, many patients use the Internet in an attempt to self-diagnose and independently find treatment options, thus avoiding (in their opinion) the need to seek in-person medical care. Additionally, electronic access to health information has expanded beyond computers to smartphones with apps that can provide users with a simple interface to personalize the health information they seek and receive.
Prior studies have shown that seeking online health information and health-related social media is more common among women, younger patients, those with a college education, and those with a higher income.3,4 However, the prevalence of health-related Internet and smartphone use among dermatology patients as well as how patients ultimately use this information is not well studied. This information about patient behavior is important because of the potential harm that may come from patient self-diagnosis, which may delay or prevent treatment, as well as the benefits of patient self-education, which may expedite diagnosis and treatment.5 We surveyed a heterogeneous patient population at 2 dermatology offices in a major academic medical center to assess the prevalence and predictors of Internet and smartphone use to obtain both general medical and dermatologic information among dermatology patients. We also evaluated the impact that health information obtained from online sources has on a patient’s degree of concern about cutaneous disease and the likelihood of seeing a dermatologist for a skin problem.
Methods
Survey and Participants
This study was approved by the institutional review board at the University of Pittsburgh, Pennsylvania. All patients aged 18 years or older who presented to the department of dermatology at 2 offices of the University of Pittsburgh Medical Center from September 2013 through July 2014 were invited to participate in an anonymous 33-question survey regarding their use of the Internet and smartphone apps to obtain health information and make health care decisions. Patients were asked to complete the survey prior to seeing a health care provider and return it to a locked box by the front desk before leaving the office. Survey questions were designed by physicians with content expertise (J.A.W. and L.K.F.) and were reviewed by a statistician with survey expertise (D.G.W.). The survey included questions about patient demographics, Internet and smartphone use (both general and health related), and specific sources accessed. The survey also inquired about the impact of health information obtained via the Internet and smartphone apps on respondents’ degree of worry about a hypothetical skin condition or lesion using a 5-point Likert scale (1=no worry; 5=very worried). Respondents also were asked which skin conditions they previously researched online and whether their findings impacted their decision to see a dermatologist. Additionally, respondents were asked to list the smartphone apps and other online health resources they had used within the last 3 months. Prior to distribution, the survey was piloted with 10 participants and no issues with comprehensibility were noted.
Statistical Analysis
We described demographic traits (eg, age, sex, race/ethnicity, level of education, income) and factors associated with access to health care (eg, specialist co-pay, travel time from dermatology office) of respondents using proportions. We evaluated respondents’ access to and use of Internet- and smartphone-based health information using proportions and used χ² tests to quantify differences by sex and age (<50 years and ≥50 years).
We analyzed the impact of Internet and smartphone-based health information on patient worry about skin conditions by obtaining median worry on a 5-point Likert scale. Due to the nonparametric nature of the data, we used the Mann-Whitney U test to quantify differences by sex and age (<50 and ≥50 years). We used multiple logistic regression to identify factors associated with 3 outcomes: (1) using the Internet to self-diagnose a dermatologic disease, (2) using the Internet to obtain dermatology-related information within the last 3 months, (3) and previously refraining from visiting a dermatologist based on reassurance from online resources. Predictors included the aforementioned demographic and health-care access–related traits. We also categorized smartphone apps used by respondents (ie, fitness/nutrition, reference, self-help, health monitoring, diagnostic aids, electronic medical record) and calculated the proportion of respondents with 1 or more of each type of app on their smartphones. Analyses were conducted in Stata 13.1 and IBM SPSS 22.0.
Results
Of 1000 patients who were invited to participate in the study, a total of 775 respondents completed the survey, yielding a response rate of 77.5%. The majority of respondents were aged 30 to 60 years (mean age [standard deviation], 44.5 [17.2] years; median age [interquartile range], 44 [29–59] years), female (66.7%), and non-Hispanic white (83.3%)(Table 1). The majority of respondents (88.8%) had completed at least some college. Nearly all respondents had medical insurance (97.8%), but annual household income and insurance co-pay varied considerably. Only 10.8% of respondents traveled more than an hour to our offices.
The majority of respondents had access to home Internet and owned a smartphone (Table 2). Use of the Internet to obtain health-related information in the 3 months prior to presentation was more common among females (77.9% vs 70.1%; P=.03) and respondents younger than 50 years (83.4% vs 62.5%; P<.001); the same was true for dermatology-related infor-mation (females: 43.2% vs 31.0%; P=.003; aged <50 years, 51.6% vs 22.2%; P<.001). The majority of respondents indicated that they use the Internet to obtain health-related information both before and after they see their doctor. Most respondents indicated that they sometimes discuss health-related information found on the Internet with a physician. Smartphone use to obtain health-related information was more common among respondents younger than 50 years versus those who were 50 years or older (55.5% vs 24.1%; P<.001), as was smartphone use to diagnose skin problems (20.0% vs 6.3%; P<.001).
In multivariable analysis, use of the Internet or a smartphone to obtain health-related information was associated with younger age (<50 years) and a higher level of education (both P<.001). Use of the Internet to obtain dermatology-related information (P<.001) and use of a smartphone to help diagnose a skin problem (P=.001) was associated with younger age (<50 years) only. Income, sex, co-pay to see a dermatologist, and travel time to the dermatology office were not associated with use of online resources for general or dermatology-specific health-related information or assistance with diagnosing a skin problem.
Of 204 respondents who indicated that they previously attempted to self-diagnose a skin condition using the Internet, the most commonly researched condition was skin cancer/moles/unknown spots (64.7%), followed by rashes (40.7%), acne (20.6%), cosmetic issues (16.2%), psoriasis (12.7%), dermatitis (3.4%), warts (1.5%), tick bites (1.0%), and lupus (1.0%)(some respondents selected more than one condition). Only 7.0% of respondents indicated that they previously had refrained from visiting a dermatologist based on reassurance from online resources. Compared to the rest of the surveyed population, these respondents were younger (P=.001), but there were no significant differences in sex, highest level of education, household income, or travel time to the dermatology office. The most commonly researched condition among these respondents was acne (12 respondents), and 11 respondents indicated that they had attempted to self-diagnose a mole or potential cancer using online sources.
Of 557 respondents who owned a smartphone, 31.8% reported using at least 1 health-related app (mean number of health apps per respondent, 1.5). Of the apps that respondents used, 45.9% focused on fitness/nutrition, 28.7% provided reference information, 13.4% were a patient portal for receiving information from their electronic medical record, 8.6% provided a health monitoring function, 1.9% served as a diagnostic aid, and 1.5% provided coping assistance and emotional support for individuals with cognitive or emotional conditions; only 1 respondent reported using an app related to dermatology.
All respondents were asked to rate their anticipated degree of worry if the Internet or a smartphone app suggested that a skin lesion was benign versus dangerous on a 5-point scale. Overall, the median worry rating increased from 3 to 5 when information accessed via the Internet or a smartphone app suggested a lesion was dangerous rather than benign. A change in worry of 2 or more points was seen in 36.1% of females and 49.1% of males (P=.002) when information obtained via the Internet indicated a lesion was dangerous and in 47.5% of females and 58.8% of males (P=.006) when a smartphone app indicated that a lesion was dangerous. When information obtained via the Internet indicated a lesion was dangerous, a change in worry of 2 or more points was seen in 41.8% of respondents who were younger than 50 years and in 41.1% of those who were 50 years or older (P=.93). When a smartphone app indicated a lesion was dangerous, a change in worry of 2 or more points was seen in 50.2% of respondents who were younger than 50 years and in 52.2% of those who were 50 years or older (P=.61).
Discussion
In this cross-sectional study, we found that health-related Internet and smartphone use among dermatology patients is common and may impact both patients’ degree of concern about a skin lesion as well as the likelihood of seeking in-person medical care if they are reassured by the results of their online findings. Age and level of education were associated with Internet and smartphone use to obtain dermatology-related health information but not factors related to health care access. More patients used the Internet or a smartphone to obtain general medical information versus dermatology-related information. Respondents who indicated that they used the Internet to obtain health-related information tended to do so before visiting their physician.
Our finding that a patient’s level of worry about a hypothetical skin condition or lesion is influenced by health information obtained via the Internet or a smartphone app is concerning. One study found that participants who used a popular search engine to look for information about vaccine safety and dangers were directed to Web sites with inaccurate information more than 50% of the time, and 65% of the information they obtained from these sites was false.6 In our study, approximately 25% of respondents had previously consulted online resources to attempt toself-diagnose a skin condition. Online sources about dermatologic conditions were consulted most frequently for information about potential skin cancers, moles, and unknown spots. A prior study showed that smartphone apps that claim to aid patients in determining whether a skin lesion is low or high risk for melanoma often are inaccurate and are associated with a high rate of missed melanomas.5 Even though we surveyed patients who did end up seeing a dermatologist, some respondents had previously opted out of seeing a dermatologist based on information they had found online. Because our study was conducted among patients who chose to seek care at a dermatology office, the problem is likely greater than estimated from our findings because we had no way of reaching individuals who decided to completely forgo a visit with a dermatologist.
Although use of the Internet to obtain health-related information was common among older adults in our population, it was nearly universal in younger adults. Health-related smartphone use was more than twice as common in younger versus older adults, which could be due to an increased comfort with technology and its integration into daily life. The fact that age and education were associated with Internet use for dermatology-related health information but not household income or travel time to the dermatology office suggests that information seeking is not due to lack of resources limiting access to dermatologic care but rather to the greater role that rapid access to online information plays in patients’ lives. Our findings are similar to another study that examined the use of online sources for general health information.7
This study has several limitations. First, there may have been some selection bias. We specifically aimed to understand the health-related Internet and smartphone use among dermatology patients, thus restricting our sample to this population. By doing so, we were unable to assess the use of such resources by the general population, particularly those individuals who chose not to see a dermatologist at all based on their own online research. Our findings may not apply to other practices and regions of the country, as we implemented our study in one geographic location and in offices of an academic practice. Although our sample size and diversity with regard to income, education, and age suggest that our results are likely generalizable to many settings, it is important to note that nearly all respondents in this study had health insurance and our findings are thus not necessarily applicable to those individuals who are uninsured.
Conclusion
Our findings suggest that the availability of online health information regarding dermatologic conditions provides dermatologists with both opportunities and challenges. Many patients consult online resources for health information, and the popularity of this practice is likely to increase with time, particularly as newer smartphones with features designed to allow users to monitor their health are developed with health-conscious consumers in mind. Most large health care systems provide patients with resources to view laboratory results and communicate with physicians online. It is important for dermatologists to be involved in the development of high-quality online content that educates the public while also emphasizing the need to seek in-person medical care, particularly in potential cases of skin cancer. It also is important for patients to be involved in the content development process to ensure that the messages they take away from online resources are the ones physicians wish to convey. Ideally, online forms of education will increase patients’ sense of self-efficacy while encouraging appropriate consultation for potentially harmful skin conditions.

Survey questions were designed by physicians with content expertise (J.A.W. and L.K.F.) and were reviewed by a statistician with survey expertise (D.G.W.). The survey included questions about patient demographics, Internet and smartphone use (both general and health related), and specific sources accessed. The survey also inquired about the impact of health information obtained via the Internet and smartphone apps on respondents’ degree of worry about a hypothetical skin condition or lesion using a 5-point Likert scale (1=no worry; 5=very worried). Respondents also were asked which skin conditions they previously researched online and whether their findings impacted their decision to see a dermatologist. Additionally, respondents were asked to list the smartphone apps and other online health resources they had used within the last 3 months. Prior to distribution, the survey was piloted with 10 participants and no issues with comprehensibility were noted.
Statistical Analysis
We described demographic traits (eg, age, sex, race/ethnicity, level of education, income) and factors associated with access to health care (eg, specialist co-pay, travel time from dermatology office) of respondents using proportions. We evaluated respondents’ access to and use of Internet- and smartphone-based health information using proportions and used χ² tests to quantify differences by sex and age (<50 years and ≥50 years).
We analyzed the impact of Internet and smartphone-based health information on patient worry about skin conditions by obtaining median worry on a 5-point Likert scale. Due to the nonparametric nature of the data, we used the Mann-Whitney U test to quantify differences by sex and age (<50 and ≥50 years). We used multiple logistic regression to identify factors associated with 3 outcomes: (1) using the Internet to self-diagnose a dermatologic disease, (2) using the Internet to obtain dermatology-related information within the last 3 months, (3) and previously refraining from visiting a dermatologist based on reassurance from online resources. Predictors included the aforementioned demographic and health-care access–related traits. We also categorized smartphone apps used by respondents (ie, fitness/nutrition, reference, self-help, health monitoring, diagnostic aids, electronic medical record) and calculated the proportion of respondents with 1 or more of each type of app on their smartphones. Analyses were conducted in Stata 13.1 and IBM SPSS 22.0.
Results
Of 1000 patients who were invited to participate in the study, a total of 775 respondents completed the survey, yielding a response rate of 77.5%. The majority of respondents were aged 30 to 60 years (mean age [standard deviation], 44.5 [17.2] years; median age [interquartile range], 44 [29–59] years), female (66.7%), and non-Hispanic white (83.3%)(Table 1). The majority of respondents (88.8%) had completed at least some college. Nearly all respondents had medical insurance (97.8%), but annual household income and insurance co-pay varied considerably. Only 10.8% of respondents traveled more than an hour to our offices.
The majority of respondents had access to home Internet and owned a smartphone (Table 2). Use of the Internet to obtain health-related information in the 3 months prior to presentation was more common among females (77.9% vs 70.1%; P=.03) and respondents younger than 50 years (83.4% vs 62.5%; P<.001); the same was true for dermatology-related infor-mation (females: 43.2% vs 31.0%; P=.003; aged <50 years, 51.6% vs 22.2%; P<.001). The majority of respondents indicated that they use the Internet to obtain health-related information both before and after they see their doctor. Most respondents indicated that they sometimes discuss health-related information found on the Internet with a physician. Smartphone use to obtain health-related information was more common among respondents younger than 50 years versus those who were 50 years or older (55.5% vs 24.1%; P<.001), as was smartphone use to diagnose skin problems (20.0% vs 6.3%; P<.001).
In multivariable analysis, use of the Internet or a smartphone to obtain health-related information was associated with younger age (<50 years) and a higher level of education (both P<.001). Use of the Internet to obtain dermatology-related information (P<.001) and use of a smartphone to help diagnose a skin problem (P=.001) was associated with younger age (<50 years) only. Income, sex, co-pay to see a dermatologist, and travel time to the dermatology office were not associated with use of online resources for general or dermatology-specific health-related information or assistance with diagnosing a skin problem.
Of 204 respondents who indicated that they previously attempted to self-diagnose a skin condition using the Internet, the most commonly researched condition was skin cancer/moles/unknown spots (64.7%), followed by rashes (40.7%), acne (20.6%), cosmetic issues (16.2%), psoriasis (12.7%), dermatitis (3.4%), warts (1.5%), tick bites (1.0%), and lupus (1.0%)(some respondents selected more than one condition). Only 7.0% of respondents indicated that they previously had refrained from visiting a dermatologist based on reassurance from online resources. Compared to the rest of the surveyed population, these respondents were younger (P=.001), but there were no significant differences in sex, highest level of education, household income, or travel time to the dermatology office. The most commonly researched condition among these respondents was acne (12 respondents), and 11 respondents indicated that they had attempted to self-diagnose a mole or potential cancer using online sources.
Of 557 respondents who owned a smartphone, 31.8% reported using at least 1 health-related app (mean number of health apps per respondent, 1.5). Of the apps that respondents used, 45.9% focused on fitness/nutrition, 28.7% provided reference information, 13.4% were a patient portal for receiving information from their electronic medical record, 8.6% provided a health monitoring function, 1.9% served as a diagnostic aid, and 1.5% provided coping assistance and emotional support for individuals with cognitive or emotional conditions; only 1 respondent reported using an app related to dermatology.
All respondents were asked to rate their anticipated degree of worry if the Internet or a smartphone app suggested that a skin lesion was benign versus dangerous on a 5-point scale. Overall, the median worry rating increased from 3 to 5 when information accessed via the Internet or a smartphone app suggested a lesion was dangerous rather than benign. A change in worry of 2 or more points was seen in 36.1% of females and 49.1% of males (P=.002) when information obtained via the Internet indicated a lesion was dangerous and in 47.5% of females and 58.8% of males (P=.006) when a smartphone app indicated that a lesion was dangerous. When information obtained via the Internet indicated a lesion was dangerous, a change in worry of 2 or more points was seen in 41.8% of respondents who were younger than 50 years and in 41.1% of those who were 50 years or older (P=.93). When a smartphone app indicated a lesion was dangerous, a change in worry of 2 or more points was seen in 50.2% of respondents who were younger than 50 years and in 52.2% of those who were 50 years or older (P=.61).
Discussion
In this cross-sectional study, we found that health-related Internet and smartphone use among dermatology patients is common and may impact both patients’ degree of concern about a skin lesion as well as the likelihood of seeking in-person medical care if they are reassured by the results of their online findings. Age and level of education were associated with Internet and smartphone use to obtain dermatology-related health information but not factors related to health care access. More patients used the Internet or a smartphone to obtain general medical information versus dermatology-related information. Respondents who indicated that they used the Internet to obtain health-related information tended to do so before visiting their physician.
Our finding that a patient’s level of worry about a hypothetical skin condition or lesion is influenced by health information obtained via the Internet or a smartphone app is concerning. One study found that participants who used a popular search engine to look for information about vaccine safety and dangers were directed to Web sites with inaccurate information more than 50% of the time, and 65% of the information they obtained from these sites was false.6 In our study, approximately 25% of respondents had previously consulted online resources to attempt toself-diagnose a skin condition. Online sources about dermatologic conditions were consulted most frequently for information about potential skin cancers, moles, and unknown spots. A prior study showed that smartphone apps that claim to aid patients in determining whether a skin lesion is low or high risk for melanoma often are inaccurate and are associated with a high rate of missed melanomas.5 Even though we surveyed patients who did end up seeing a dermatologist, some respondents had previously opted out of seeing a dermatologist based on information they had found online. Because our study was conducted among patients who chose to seek care at a dermatology office, the problem is likely greater than estimated from our findings because we had no way of reaching individuals who decided to completely forgo a visit with a dermatologist.
Although use of the Internet to obtain health-related information was common among older adults in our population, it was nearly universal in younger adults. Health-related smartphone use was more than twice as common in younger versus older adults, which could be due to an increased comfort with technology and its integration into daily life. The fact that age and education were associated with Internet use for dermatology-related health information but not household income or travel time to the dermatology office suggests that information seeking is not due to lack of resources limiting access to dermatologic care but rather to the greater role that rapid access to online information plays in patients’ lives. Our findings are similar to another study that examined the use of online sources for general health information.7
This study has several limitations. First, there may have been some selection bias. We specifically aimed to understand the health-related Internet and smartphone use among dermatology patients, thus restricting our sample to this population. By doing so, we were unable to assess the use of such resources by the general population, particularly those individuals who chose not to see a dermatologist at all based on their own online research. Our findings may not apply to other practices and regions of the country, as we implemented our study in one geographic location and in offices of an academic practice. Although our sample size and diversity with regard to income, education, and age suggest that our results are likely generalizable to many settings, it is important to note that nearly all respondents in this study had health insurance and our findings are thus not necessarily applicable to those individuals who are uninsured.
Conclusion
Our findings suggest that the availability of online health information regarding dermatologic conditions provides dermatologists with both opportunities and challenges. Many patients consult online resources for health information, and the popularity of this practice is likely to increase with time, particularly as newer smartphones with features designed to allow users to monitor their health are developed with health-conscious consumers in mind. Most large health care systems provide patients with resources to view laboratory results and communicate with physicians online. It is important for dermatologists to be involved in the development of high-quality online content that educates the public while also emphasizing the need to seek in-person medical care, particularly in potential cases of skin cancer. It also is important for patients to be involved in the content development process to ensure that the messages they take away from online resources are the ones physicians wish to convey. Ideally, online forms of education will increase patients’ sense of self-efficacy while encouraging appropriate consultation for potentially harmful skin conditions.
Patients increasingly use the Internet and/or smartphone applications (apps) to seek health information and track personal health data,1,2 typically in the spirit of being a more educated consumer. However, many patients use the Internet in an attempt to self-diagnose and independently find treatment options, thus avoiding (in their opinion) the need to seek in-person medical care. Additionally, electronic access to health information has expanded beyond computers to smartphones with apps that can provide users with a simple interface to personalize the health information they seek and receive.
Prior studies have shown that seeking online health information and health-related social media is more common among women, younger patients, those with a college education, and those with a higher income.3,4 However, the prevalence of health-related Internet and smartphone use among dermatology patients as well as how patients ultimately use this information is not well studied. This information about patient behavior is important because of the potential harm that may come from patient self-diagnosis, which may delay or prevent treatment, as well as the benefits of patient self-education, which may expedite diagnosis and treatment.5 We surveyed a heterogeneous patient population at 2 dermatology offices in a major academic medical center to assess the prevalence and predictors of Internet and smartphone use to obtain both general medical and dermatologic information among dermatology patients. We also evaluated the impact that health information obtained from online sources has on a patient’s degree of concern about cutaneous disease and the likelihood of seeing a dermatologist for a skin problem.

Startup Pharmacy Takes Mail-Order to Next Level, Could Solve Medication Management Issue for Millions
It only takes one idea to help change the face of medicine and, recently, Forbes posted an article outlining a small startup pharmacy that could change the way we get our medication. Manchester, N.H.-based Pill Pack takes the whole mail-order pharmacy to a new level.
Medication management can be a major issue for seniors and their caregivers. Seniors are at risk for such problems as overmedication and drug interactions, if medications are not properly managed.
An UpToDate article says that a survey for adults aged 57-85 shows:
- At least one prescription medication was used by 81%;
- Five or more prescription medications were used by 29% of the overall survey population and by 36% of people aged 75 to 85 years; and
- 46% of prescription users also took at least one over-the-counter medication.
Hospitalists see it every day; the readmit because prescribed medication isn’t taken correctly. Possibly, Pill Pack might be one step in the right direction. TH

Stent-retriever thrombectomy reduces poststroke disability
For patients with proximal large-vessel anterior stroke, neurovascular thrombectomy with a stent retriever plus medical therapy in the REVASCAT trial reduced the severity of poststroke disability and raised the rate of functional independence, compared with medical therapy alone, according to a report in the New England Journal of Medicine.
To assess the efficacy and safety of thrombectomy with a stent retriever, investigators performed a prospective, open-label, phase III clinical trial involving 206 adults up to 85 years of age treated at four designated comprehensive stroke centers in Catalonia, Spain.
All the participants in the Randomized Trial of Revascularization With Solitaire FR Device Versus Best Medical Therapy in the Treatment of Acute Stroke Due to Anterior Circulation Large Vessel Occlusion Presenting Within Eight Hours of Symptom Onset (REVASCAT) had either not responded to intravenous alteplase administered within 4.5 hours of symptom onset or had contraindications to alteplase therapy. They were randomly assigned in equal numbers to undergo endovascular treatment with a stent retriever or medical therapy alone, said Dr. Tudor G. Jovin, director of the Stroke Institute, University of Pittsburgh Medical Center, and his associates.
The trial was halted early when the first interim analysis showed “lack of equipoise” between the two study groups, and because emerging results from three other studies demonstrated the superior efficacy of thrombectomy. The primary efficacy outcome measure – severity of disability at 90 days, as measured by expert assessors blinded to treatment assignment – significantly favored thrombectomy over medical therapy. The proportion of patients who achieved functional independence by day 90 on the modified Rankin scale also demonstrated the clear superiority of thrombectomy (43.7%) over medical therapy (28.2%).
Only 6.5 patients would need to be treated with thrombectomy to prevent 1 case of functional dependency or death. In addition, “thrombectomy was associated with a shift toward better outcomes across the entire spectrum of disability,” Dr. Jovin and his associates said (N. Engl. J. Med. 2015 [doi:10.1056/NEJMoa1503780]).
Regarding safety, the rate of death at 90 days did not differ significantly between patients who underwent thrombectomy (18.4%) and control subjects (15.5%). Rates of intracranial hemorrhage were the same, 1.9%, in both groups, and rates of other serious adverse events also were similar.
These findings are consistent with those of several other recently reported clinical trials and show that “in patients with acute stroke caused by a proximal large-vessel occlusion and an absence of a large infarct on baseline imaging, mechanical thrombectomy with [a] stent retriever was safe and led to improved clinical outcomes, as compared with medical therapy alone,” the investigators said.
REVASCAT was funded by an unrestricted grant from Covidien, maker of the stent retriever, and by grants from several Spanish research institutes. Dr. Jovin reported ties to Covidien, Silk Road Medical, Air Liquide, Medtronic, and Stryker Neurovascular.
For patients with proximal large-vessel anterior stroke, neurovascular thrombectomy with a stent retriever plus medical therapy in the REVASCAT trial reduced the severity of poststroke disability and raised the rate of functional independence, compared with medical therapy alone, according to a report in the New England Journal of Medicine.
To assess the efficacy and safety of thrombectomy with a stent retriever, investigators performed a prospective, open-label, phase III clinical trial involving 206 adults up to 85 years of age treated at four designated comprehensive stroke centers in Catalonia, Spain.
All the participants in the Randomized Trial of Revascularization With Solitaire FR Device Versus Best Medical Therapy in the Treatment of Acute Stroke Due to Anterior Circulation Large Vessel Occlusion Presenting Within Eight Hours of Symptom Onset (REVASCAT) had either not responded to intravenous alteplase administered within 4.5 hours of symptom onset or had contraindications to alteplase therapy. They were randomly assigned in equal numbers to undergo endovascular treatment with a stent retriever or medical therapy alone, said Dr. Tudor G. Jovin, director of the Stroke Institute, University of Pittsburgh Medical Center, and his associates.
The trial was halted early when the first interim analysis showed “lack of equipoise” between the two study groups, and because emerging results from three other studies demonstrated the superior efficacy of thrombectomy. The primary efficacy outcome measure – severity of disability at 90 days, as measured by expert assessors blinded to treatment assignment – significantly favored thrombectomy over medical therapy. The proportion of patients who achieved functional independence by day 90 on the modified Rankin scale also demonstrated the clear superiority of thrombectomy (43.7%) over medical therapy (28.2%).
Only 6.5 patients would need to be treated with thrombectomy to prevent 1 case of functional dependency or death. In addition, “thrombectomy was associated with a shift toward better outcomes across the entire spectrum of disability,” Dr. Jovin and his associates said (N. Engl. J. Med. 2015 [doi:10.1056/NEJMoa1503780]).

Study suggests need for change in matching criteria

A donor’s CD8 cell count can affect the outcome of hematopoietic stem cell transplant (HSCT) in older patients, according to a study published in the Journal of Clinical Oncology.
Older patients who received stem cells from unrelated donors with higher CD8 counts had a significantly lower risk of relapse and higher rate of
survival than patients who received grafts with lower CD8 counts, even if those grafts were from matched sibling donors.
This suggests that screening for donor T-cell characteristics could optimize donor selection and ultimately lead to more successful transplants in an older population, study investigators said.
“Developing better tools to identify ideal donors is an exciting prospect and fundamental to improving transplant outcomes,” said Ran Reshef, MD, of the Abramson Cancer Center at the University of Pennsylvania in Philadelphia.
“There may be suitable donors out there who are overlooked because they are considered a poorer match by today’s donor selection algorithms. Refining the screening method could greatly increase the chances of finding the most appropriate donor, one that will induce the most potent graft-vs-tumor response.”
For this study, Dr Reshef and his colleagues retrospectively evaluated associations between a graft’s T-cell dose and outcomes in 200 patients undergoing HSCT to treat acute myeloid leukemia, myelodysplastic syndrome, non-Hodgkin lymphoma, and other hematologic disorders.
The investigators looked specifically at CD4 and CD8 counts and found the number of CD8 cells in the graft had an impact on survival. They also found that high CD8 cell counts were much more common among young donors.
The 4-year overall survival rates were 59% for patients who received grafts from younger (<50 years), unrelated donors with high CD8 counts; 18% for those who received grafts from younger, unrelated donors with low CD8 counts; and 33% for patients who received grafts from older (>50 years), HLA-matched sibling donors.
In multivariable analysis, CD8 count was an independent predictor of relapse (adjusted hazard ratio [aHR]=0.43; P=0.009), relapse-free survival (aHR=0.50; P=0.006), and overall survival (aHR=0.57; P=0.04).
The investigators also assessed the effect of CD8 count on survival using a cutoff of 0.72 x 108 CD8 cells/kg. They found that patients with CD8 doses above this cutoff had significantly better relapse-free survival (P=0.005) and overall survival (P=0.007) rates than patients with CD8 doses below this cutoff.
These results suggest it would be better to use a younger, unrelated donor graft with a high CD8 cell count rather than an older sibling donor, the investigators said. However, this strategy should be tested in a prospective trial.
“This is a method deserving additional investigation,” Dr Reshef said, “which could refine the standardized matching system used by registries, such as Be the Match and others, and ultimately optimize the donor pool for older patients undergoing these transplants.”

Follow-up PET/CT has ‘clinical value’ in NHL
BALTIMORE—Post-treatment PET/CT scans may be necessary for some patients with non-Hodgkin lymphoma (NHL), according to a presentation at the 2015 SNMMI Annual Meeting.
“[T]he role of post-treatment PET/CT has been controversial,” said Mehdi Taghipour, MD, of Johns Hopkins University in Baltimore, Maryland.
“Our study proves that 39% of follow-up PET/CT scans added clinical value, which represents a significant improvement in NHL patient care.”
Dr Taghipour presented the details of this study at the meeting as abstract 599.
He and his colleagues had examined 560 PET/CT scans from 204 patients. Imaging was performed 6 months or more after the patient completed primary therapy.
The researchers assessed the value of follow-up PET/CT by conducting statistical analyses to determine changes in patient management and evaluated the accuracy of these scans compared to either histopathology or an additional 6-month follow-up.
Results showed that the sensitivity of PET/CT for detecting relapsed NHL was 95.1%, and the specificity was 90.5%. Positive and negative predictive values were 84.5% and 97.1%, respectively.
The overall accuracy of follow-up PET/CT with the common imaging agent fluorodeoxyglucose (FDG) was 92.1%.
Follow-up PET/CT led to changes in patient management in 17% of cases, and new treatments were initiated after 15.7% of scans. More than 69% of scans were performed without prior clinical suspicion of recurrence, and 30.7% of scans were ordered because of suspected disease.
More than 22% of follow-up scans showed suspected disease when there was no clinical suspicion for disease recurrence, and the presence of disease was ruled out in 17.4% of scans where the treating physician had suspected recurrence prior to the scan.

A better FLT3 inhibitor for AML?
© ASCO/Scott Morgan
CHICAGO—A dual inhibitor of FLT3 and Axl may produce more durable responses than other FLT3 inhibitors and improve survival in patients with FLT3-positive, relapsed or refractory acute myeloid leukemia (AML), according to a speaker at the 2015 ASCO Annual Meeting.
The FLT3/Axl inhibitor, ASP2215, has not been compared against other FLT3 inhibitors directly, and the data presented were from a phase 1/2 study.
However, the speaker said ASP2215 provided “potent and sustained” inhibition of FLT3 and produced an overall response rate (ORR) of 52% among FLT3-positive patients.
The median duration of response for these patients was 18 weeks, and their median overall survival was about 27 weeks.
Mark J. Levis, MD, PhD, of the Sidney Kimmel Comprehensive Cancer Center at Johns Hopkins in Baltimore, Maryland, presented these results at ASCO as abstract 7003.*
“We’ve been studying FLT3 inhibitors for a number of years now,” Dr Levis began, “and we think they show significant clinical promise, [but] they also have problems.”
He noted that some of these drugs haven’t been particularly safe or well-tolerated. They can cause gastrointestinal toxicity, hand-foot syndrome, QT prolongation, and myelosuppression.
However, the most intriguing problem with FLT3 inhibitors, according to Dr Levis, is the emergence of resistance-conferring point mutations observed in studies of some of the newer drugs, such as sorafenib and quizartinib.
“So in that context, here we have ASP2215,” Dr Levis said. “This is a type 1 FLT3 tyrosine kinase inhibitor, and, as such, it has activity against not only wild-type and ITD-mutated FLT3 but also against those resistance-conferring point mutations typically found in the activation loop at the so-called gatekeeper residue (F691L).”
With this in mind, he and his colleagues conducted a phase 1/2 trial of ASP2215. The study was sponsored by Astellas Pharma Global Development, Inc., the company developing ASP2215.
The trial was open to patients with relapsed or refractory AML, irrespective of their FLT3 mutation status. The researchers’ goal was to identify a safe, tolerable dose of ASP2215 that fully inhibited FLT3.
The team used a standard 3+3 design, with dose levels ranging from 20 mg to 450 mg once daily. They expanded every cohort until they reached a dose-limiting toxicity.
In all, the trial enrolled 198 patients, 24 in the dose-escalation cohorts and 174 in the dose-expansion cohorts. The patients’ median age was 62 (range, 21-90), and 53.1% were male.
Nearly 66% of patients had FLT3 mutations, 29.4% were FLT3-negative, and 5.2% had unknown FLT3 status. About 35% of patients had received 1 prior line of therapy, 26.3% had 2, 33.5% had 3 or more, and 5.7% had an unknown number of prior therapies.
Safety results
In the 194 patients who were evaluable for safety, treatment-emergent adverse events included diarrhea (13.4%), fatigue (12.4%), AST increase (11.3%), ALT increase (9.3%), thrombocytopenia (7.7%), anemia (7.2%), peripheral edema (7.2%), constipation (6.7%), nausea (6.7%), dizziness (6.2%), vomiting (5.7%), and dysgeusia (5.2%).
Serious adverse events included febrile neutropenia (27.3%), sepsis (11.9%), disease progression (10.3%), pneumonia (8.8%), hypotension (5.7%), and respiratory failure (5.7%).
“The kinds of side effects we saw were typical for a relapsed/refractory AML population,” Dr Levis said. “Nothing really stood out. Any trial of relapsed/refractory AML is going to have febrile neutropenia and sepsis, and those were our dominant, serious adverse events. There was no real safety signal here that was unique to the drug, we felt.”
The researchers said the maximum-tolerated dose of ASP2215 was 300 mg, as 2 patients who received the 450 mg dose experienced dose-limiting toxicities. One was grade 3 diarrhea, and the other was grade 3 AST elevation.
Response and survival
Among the 127 patients who were FLT3-positive, the ORR was 52% (n=66). The complete response (CR) rate was 6.3% (n=8). The composite CR rate, which includes CRs with incomplete hematologic recovery (CRi) and incomplete platelet recovery (CRp), was 40.9% (n=52). And the partial response (PR) rate was 11% (n=14).
“As we scale up the dose, the PRs shift on over to CRis, and the dominant response is, in fact, a complete response with incomplete count recovery,” Dr Levis said. “The categories where we had the largest number of responses were the 120 mg and 200 mg categories. We didn’t really have enough patients in the 300 mg category to comment on it. ”
For the FLT3-positive patients, the median duration of response was 126 days.
“The duration of response really stood out here,” Dr Levis said. “It’s over 4 months. That is something we really didn’t see with the other drugs, and I suspect that is a reflection of the suppression of the outgrowth of these resistance mutations.”
Unfortunately, FLT3-wild-type patients did not fare as well. The ORR among these patients was 8.8%. None of the patients achieved a CR, 3 had a composite CR (5.3%), and 2 had a PR (3.5%).
Among the FLT3-positive patients, the median overall survival was about 27 weeks. It was 128 days in the 20 mg dose cohort (n=13), 105.5 days in the 40 mg cohort (n=8), 201 days in the 80 mg cohort (n=12), 199 days in the 120 mg cohort (n=40), and 161 days in the 200 mg cohort (n=45). Dr Levis did not present survival data for the 300 mg or 450 mg cohorts, which included 7 and 2 patients, respectively.
“[Relapsed/refractory AML] is a population that has a median survival of about 3 months with conventional therapy, at least by historical publications,” Dr Levis noted. “If you look at survival in this trial, patients treated at the FLT3-inhibitory doses [had a] greater than 6-month median survival.”
He added that studies of ASP2215 in combination with other agents are ongoing in patients with newly diagnosed AML. And phase 3 trials of ASP2215 at the 120 mg dose, with the option of scaling up to 200 mg, are planned.

Unfortunately, FLT3-wild-type patients did not fare as well. The ORR among these patients was 8.8%. None of the patients achieved a CR, 3 had a composite CR (5.3%), and 2 had a PR (3.5%).
Among the FLT3-positive patients, the median overall survival was about 27 weeks. It was 128 days in the 20 mg dose cohort (n=13), 105.5 days in the 40 mg cohort (n=8), 201 days in the 80 mg cohort (n=12), 199 days in the 120 mg cohort (n=40), and 161 days in the 200 mg cohort (n=45). Dr Levis did not present survival data for the 300 mg or 450 mg cohorts, which included 7 and 2 patients, respectively.
“[Relapsed/refractory AML] is a population that has a median survival of about 3 months with conventional therapy, at least by historical publications,” Dr Levis noted. “If you look at survival in this trial, patients treated at the FLT3-inhibitory doses [had a] greater than 6-month median survival.”
He added that studies of ASP2215 in combination with other agents are ongoing in patients with newly diagnosed AML. And phase 3 trials of ASP2215 at the 120 mg dose, with the option of scaling up to 200 mg, are planned.

CHICAGO—A dual inhibitor of FLT3 and Axl may produce more durable responses than other FLT3 inhibitors and improve survival in patients with FLT3-positive, relapsed or refractory acute myeloid leukemia (AML), according to a speaker at the 2015 ASCO Annual Meeting.
The FLT3/Axl inhibitor, ASP2215, has not been compared against other FLT3 inhibitors directly, and the data presented were from a phase 1/2 study.
However, the speaker said ASP2215 provided “potent and sustained” inhibition of FLT3 and produced an overall response rate (ORR) of 52% among FLT3-positive patients.
The median duration of response for these patients was 18 weeks, and their median overall survival was about 27 weeks.
Mark J. Levis, MD, PhD, of the Sidney Kimmel Comprehensive Cancer Center at Johns Hopkins in Baltimore, Maryland, presented these results at ASCO as abstract 7003.*
“We’ve been studying FLT3 inhibitors for a number of years now,” Dr Levis began, “and we think they show significant clinical promise, [but] they also have problems.”
He noted that some of these drugs haven’t been particularly safe or well-tolerated. They can cause gastrointestinal toxicity, hand-foot syndrome, QT prolongation, and myelosuppression.
However, the most intriguing problem with FLT3 inhibitors, according to Dr Levis, is the emergence of resistance-conferring point mutations observed in studies of some of the newer drugs, such as sorafenib and quizartinib.
“So in that context, here we have ASP2215,” Dr Levis said. “This is a type 1 FLT3 tyrosine kinase inhibitor, and, as such, it has activity against not only wild-type and ITD-mutated FLT3 but also against those resistance-conferring point mutations typically found in the activation loop at the so-called gatekeeper residue (F691L).”
With this in mind, he and his colleagues conducted a phase 1/2 trial of ASP2215. The study was sponsored by Astellas Pharma Global Development, Inc., the company developing ASP2215.
The trial was open to patients with relapsed or refractory AML, irrespective of their FLT3 mutation status. The researchers’ goal was to identify a safe, tolerable dose of ASP2215 that fully inhibited FLT3.
The team used a standard 3+3 design, with dose levels ranging from 20 mg to 450 mg once daily. They expanded every cohort until they reached a dose-limiting toxicity.
In all, the trial enrolled 198 patients, 24 in the dose-escalation cohorts and 174 in the dose-expansion cohorts. The patients’ median age was 62 (range, 21-90), and 53.1% were male.
Nearly 66% of patients had FLT3 mutations, 29.4% were FLT3-negative, and 5.2% had unknown FLT3 status. About 35% of patients had received 1 prior line of therapy, 26.3% had 2, 33.5% had 3 or more, and 5.7% had an unknown number of prior therapies.
Safety results
In the 194 patients who were evaluable for safety, treatment-emergent adverse events included diarrhea (13.4%), fatigue (12.4%), AST increase (11.3%), ALT increase (9.3%), thrombocytopenia (7.7%), anemia (7.2%), peripheral edema (7.2%), constipation (6.7%), nausea (6.7%), dizziness (6.2%), vomiting (5.7%), and dysgeusia (5.2%).
Serious adverse events included febrile neutropenia (27.3%), sepsis (11.9%), disease progression (10.3%), pneumonia (8.8%), hypotension (5.7%), and respiratory failure (5.7%).
“The kinds of side effects we saw were typical for a relapsed/refractory AML population,” Dr Levis said. “Nothing really stood out. Any trial of relapsed/refractory AML is going to have febrile neutropenia and sepsis, and those were our dominant, serious adverse events. There was no real safety signal here that was unique to the drug, we felt.”
The researchers said the maximum-tolerated dose of ASP2215 was 300 mg, as 2 patients who received the 450 mg dose experienced dose-limiting toxicities. One was grade 3 diarrhea, and the other was grade 3 AST elevation.
Response and survival
Among the 127 patients who were FLT3-positive, the ORR was 52% (n=66). The complete response (CR) rate was 6.3% (n=8). The composite CR rate, which includes CRs with incomplete hematologic recovery (CRi) and incomplete platelet recovery (CRp), was 40.9% (n=52). And the partial response (PR) rate was 11% (n=14).
“As we scale up the dose, the PRs shift on over to CRis, and the dominant response is, in fact, a complete response with incomplete count recovery,” Dr Levis said. “The categories where we had the largest number of responses were the 120 mg and 200 mg categories. We didn’t really have enough patients in the 300 mg category to comment on it. ”
For the FLT3-positive patients, the median duration of response was 126 days.
“The duration of response really stood out here,” Dr Levis said. “It’s over 4 months. That is something we really didn’t see with the other drugs, and I suspect that is a reflection of the suppression of the outgrowth of these resistance mutations.”
