Copenhagen – Relapse of acute myeloid leukemia among older adults may be caused by pre-leukemic stem cells lurking after treatment.

Among 107 adults with AML treated in a German multicenter clinical trial, 36% were found to have pre-treatment mutations that persisted after therapy, reported Dr. Klaus Metzeler of the University of Munich.

“Mutation persistence after chemotherapy was way more common in older patients, and importantly, patients with persisting mutations had a significantly higher risk of AML recurrence,” he said at a briefing prior to presentation of the data at the annual congress of the European Hematology Association.

The higher relapse risk associated with persistent mutations remained even after adjustment for patient age, cytogenetics, and other risk factors, he noted.

AML can arise from a clone of pre-leukemic stem cells, and it is known that pre-leukemic clones carry genetic mutations that can later be found in leukemic cells. The investigators hypothesized that pre-leukemic clones persisting after chemotherapy could be related treatment outcomes and survival.

To test this idea, they analyzed samples collected from bone marrow or peripheral blood of 107 adults with AML (median age 53 years, range 20-80 years) both before chemotherapy and during the first remission. The majority of remission samples (92%) were collected within the first 180 days of remission.

The investigators looked for the presence of 68 genes known to be recurrently mutated in myeloid malignancies, and identified any sequence alterations with a variant allele frequency of 2% or greater as either known or possible driver mutations, variants of unknown significance, or known germline polymorphisms.

A total of 426 driver mutations in 42 genes were detected in samples collected at diagnosis. In all, 69 patients (64%) had no mutations following chemotherapy. Among the remaining 38 patients, there were 66 persistent mutations in 15 genes. The most common persistent mutations were in the genes DNMT3A, TET2, SRF2, and ASXL1.

“Those are precisely those mutations that are known to occur in these pre-leukemic clones,” Dr. Metzeler said.

Mutations found in the pre-treatment but not the remission samples included those in NMP1, FLT3, WT1, and NRAS.

As noted, patients with one or more persistent mutations tended to be older than those with no mutations, with a median age of 63 years vs. 48 years (P less than .001). Persistence of one or more driver mutations in remission was associated with both significantly shorter relapse-free survival (median 14.3 months vs. 58.0 months, P = .009) and shorter overall survival (median, 39.6 months vs. more than 72 months; P = .005).

In multivariate analyses controlling for age, European LeukemiaNet genetic risk groups, and remission status (complete remission vs. complete remission with incomplete recovery of counts), any persistent mutations was associated with significantly worse relapse-free survival (hazard ratio, 2.2, P =.02) and overall survival (HR, 3.0, P = .008). 

“It is well known that older AML patients have a poor prognosis, but the reasons for that aren’t fully understood yet. So the hypothesis that would come from our data is that frequent persistence of pre-leukemic clones may be one potential explanation for the higher relapse risk that we found in older patients,” Dr. Metzeler said.

Asked how clinicians might go about targeting the escaped mutations, Dr. Metzeler noted that the incidence of pre-leukemic somatic mutations among healthy 70-year-olds is about 10%.

“So the challenge will be to identify those patients who will actually relapse, and then an option in fit patients would be an allogeneic transplant. We don’t have targeted agents at the moment where we can target these specific mutations, and it would be relatively hard to justify giving those patients additional chemotherapy at this point,” he said.

“What this is showing for the first time is a clue as to why a subset will relapse, and now we know that this group exists with these pre-leukemic clones, we can begin to ask questions about why it is they relapse or don’t relapse. Is it something to do with the immune system in those patients who don’t relapse?” commented EHA president Tony Green, M.D., who was not involved in the study, but attended the briefing.

Using next-generation sequencing (NGS) technology, a team of researchers has discovered 2 new subtypes of pediatric B-cell precursor acute lymphoblastic leukemia (BCP ALL).

The 2 new subtypes, called DUX4-rearranged and ETV6/RUNX1-like, may improve risk stratification and targeted therapeutic options for treatment of the disease, the researchers say.

Previous studies have defined 6 major groups of ALL in children. The 2 new types can now be added to these groups.

The research team performed RNA sequencing in a population-based series of 195 pediatric BCP ALL cases, all under 18 years.

They found gene fusions present in 65% of BCP ALL cases. They also identified several new fusions along with the 2 novel subtypes.

The DUX4-rearranged subtype occurs “when a gene called DUX4, which is normally inactive in blood cells, becomes activated when the gene is relocated in the genome,” corresponding author Henrik Lilljebjörn, of Lund University in Sweden, said.

The DUX4-rearranged subtype was represented in 4% of the cases. It led to overexpression of DUX4 and frequently occurred together with intragenic ERG deletions.

The team observed a borderline significance (P=0.051) for age in cases with DUX4 rearrangements. Those with DUX4 rearrangements tended to be from older patients compared to cases lacking the fusion, with a median age of 6.5 year versus 4 years, respectively. The authors noted that this association needs to be confirmed in larger cohorts.

The ETV6/RUNX1-like subtype “resembles a previously known type of childhood leukemia,”Lilljebjörn said, “but is caused by other genetic mutations."

The ETV6/RUNX1-like subtype was represented in 3% of the BCP ALL cases.

According to the team, if all known subtypes are taken into consideration, “98% of the BCP ALL cases could be classified into distinct genetic subtypes with a known underlying driver mutation, or, less commonly, with a rare in-frame gene fusion,” they wrote.

“Finding the critical mutations in the diseased cells,” principal investigator Thoas Fioretos, MD, PhD, of Lund University, explained, “is an important condition for understanding the mechanisms of the disease and ultimately discovering new therapies.”

The investigators published their work in Nature Communications.

The research was funded mainly by The Swedish Childhood Cancer Foundation, The Swedish Cancer Society, The Swedish Research Council, the Faculty of Medicine at Lund University and Region Skåne.

NEW ORLEANS — Two researchers shared innovative ideas at the annual scientific sessions of the American Diabetes Association for tapping virtually unlimited supplies of islet cells with less risk of an immune reaction.

Transplanting pancreatic islet stem cells from deceased donors into patients with type 1 diabetes has long been known to be an effective way of improve blood-glucose levels and temporarily eliminate the need for insulin injections, but getting an adequate supply of islet cells to treat the 1 million-2 million Americans with Type 1 diabetes, not to mention the risk of rejection and the need for long-term immunosuppressive therapy, makes this approach challenging.

At the University of Pittsburgh, investigators have developed a way to harvest islet cells from genetically engineered pigs and implant them into monkeys, while at the Harvard Stem Cell Institute in Boston, researchers have used gene editing to grow islet cells from blood cells.

“Human islet cells are in very scarce supply and will never solve the problem of diabetes,” said Dr. David K.C. Cooper, professor at the Thomas E. Starzi Transplantation Institute at the University of Pittsburgh. But growing evidence has shown that islet cells harvested from pigs could provide a viable source.

The challenge with stem cells from deceased human donors is that they require long term immunosuppression therapy to prevent the host body from rejecting them. When Dr. Cooper and his team injected islet cells from genetically engineered pigs into the stomachs of monkeys, they found the monkeys were able to maintain blood glucose control for about a year while on “fairly basic immunosuppressive therapy.” Dr. Cooper explained that the immunosuppressive regimen is a nonthrombogenic, monoclonal antibody not yet approved by the Food and Drug Administration. He noted that work at the Seoul National University in Korea has found similar results in monkeys out to 2 years.

The concept involves raising genetically engineered pigs in a biosecure facility, of which there are “two or three” in the United States, to ensure the cells are infection free. “The pig will be the answer to our problems,” Dr. Cooper said.

At Harvard, meanwhile, researchers are developing a way to produce pluripotent stem cells using an individual’s own blood cells that function like embryonic stem cells, but can multiply in a virtually unlimited fashion, Chad Cowan, PhD, reported. The challenge with using stem cells produced from an individual’s own cells has been the “immune barrier” – that is, the person’s immune system would attack the new cells.

However, Dr. Cowan and his team have found a way around this so-called “immune barrier” by producing “universal donor” pluripotent stem cell lines.

“You have an unlimited supply of cells,” Dr. Cowan said. “The key, though, is to teach these cells to do something, and because they come from a very early stage in development, they have the ability to become any of the adult cells in the human body. Our mission has been to teach them to become insulin-producing beta cells.”

The idea is to grow an “off-the-shelf, quality-controlled” product that can be produced in large numbers. By editing the genes, the researchers aim to reduce the immunogenicity of these cells and induce tolerance.

The work is some time away from human trials. “Once created, the next step would be to test these universal donor pluripotent stem cell lines in a humanized mouse model of type 1 diabetes,” Dr. Cowan said.

This type of gene editing also could have implications beyond diabetes, Dr. Cowan said. “If successful, our proposed work could have an enormous impact on regenerative medicine,” he said. “It could lead the way to rigorously tested universal donor stem cells that could be grown and differentiated into very large numbers of cells, made widely available to all medical institutions and used on demand to treat patients suffering from type 1 diabetes and a variety of degenerative illnesses,” including Parkinson’s disease.

Dr. Cowan and Dr. Cooper reported having no financial disclosures.

CHICAGO – Extending adjuvant aromatase inhibitor (AI) therapy from 5 years to 10 years further reduces the risk of recurrence and new breast cancer in postmenopausal women treated for early disease, according to findings of the MA17.R trial.

In the phase III trial conducted by the Canadian Cancer Trials Group and the North American Breast Cancer Group, 1,918 postmenopausal women who had completed about 5 years of AI therapy (preceded by tamoxifen in the majority of cases) were randomized to take the AI letrozole or to stop therapy by taking placebo for an additional 5 years.

Compared with peers who stopped, women who continued AI therapy for 5 more years had a 34% lower risk of recurrence or contralateral breast cancer, investigators reported in sessions and a press briefing at the annual meeting of the American Society of Clinical Oncology. The trade-off was a small increase in the rates of skeletal adverse events such as fractures; quality of life was essentially unaffected.

“MA17.R is the first study to show the benefit of extending an adjuvant aromatase inhibitor beyond 5 years,” commented lead investigator Paul E. Goss, M.D., director of the Breast Cancer Research Program at the Massachusetts General Hospital and a professor of medicine at Harvard Medical School, both in Boston. “Unlike many anticancer therapies, aromatase inhibitors are readily accessible around the world, and therefore, our results will further improve the outcome of many women with breast cancer.”

The disease-free survival curves will likely separate further, given a “legacy effect” of endocrine therapy that persists after it ends, he predicted. “And I think overall survival will eventually become positive in MA.17R. … The Food and Drug Administration has taken the opinion that overall survival follows disease-free survival like night follows day for endocrine therapies, and I think they are correct, I think that’s what we see in all the trials.”

Implications

It remains unclear how patients should be managed after 10 years of an AI, according to Dr. Goss. “That’s uncharted waters,” he elaborated. “We know from the curve of the natural history of this disease that it chronically relapses, and we continue to see patients 25 years after their primary diagnosis with a recurrence.” Some data in mice suggest there may be benefit from continuing the AI until recurrence. “I don’t think that would be entered into in clinical practice as a rule, because there is no clinical trial of that,” he said. “But this data will now take the aromatase inhibitors out to 10 years.”

The MA.17R trial’s findings show that extended duration of AI therapy is “clinically valuable,” according to ASCO expert Harold J. Burstein, M.D., Ph.D., a senior physician at the Dana-Farber Cancer Institute and an associate professor of medicine at the Harvard Medical School in Boston. He predicted the findings will have at least two consequences.

“One is tremendous interest in longer durations of therapy with the AI, but also some tailoring of treatment based on how the patient has fared with their therapy and on their baseline risk of recurrence. So women who have less risky cancer will probably be less inclined to pursue these longer durations, and women who have higher-risk cancers will be more inclined,” he explained.

Also, “women who have finished 5 years of an AI without any prior tamoxifen I think are going to be very compelled by these data, whereas women who have had 5 years of tamoxifen, 5 years of an AI, and are already 10 years out probably get less benefit numerically from yet longer duration of therapy,” he added. “And we are certainly not at the point of saying that women should be on these drugs for the rest of their lives.”

MA.17R design

Postmenopausal women were eligible for MA.17R if they had undergone resection of hormone receptor–positive early breast cancer and had already completed about 5 years of therapy with any of the three AIs currently on the market. In the large majority of cases, they also had previously received tamoxifen.

Many of the women came from the parent MA.17 trial, which tested an initial 5 years of letrozole (brand name Femara) against placebo after tamoxifen therapy. Longer-term results of that trial, previously reported (J Clin Oncol. 2012;30:718-21), showed that this duration of letrozole had a significant disease-free survival benefit (hazard ratio, .52) and overall survival benefit (HR, .61).

In the MA.17R trial, the women were randomized to letrozole or a placebo for an additional 5 years, with a primary endpoint of disease-free survival and secondary endpoints including safety and quality of life.

Efficacy and safety

After a median follow-up of 6.3 years, the 5-year rate of disease-free survival was 95% with letrozole and 91% with placebo, according to results reported by Dr. Goss in a plenary session at the meeting and simultaneously published (N Engl J Med. 2016. June 5 doi: 10.1056/NEJMoa1604700).

The difference translated to a more than one-third reduction in the risk of disease recurrence or the occurrence of contralateral breast cancer (HR, .66; P = .01). Roughly three-fourths of recurrences were distant.

The groups did not differ significantly with respect to the rate of overall survival, which was 93% with letrozole and 94% with placebo.

The annual incidence of contralateral breast cancer was sharply lower in the letrozole group, at 0.21%, than in the placebo group, at 0.49%, translating to a more than one-half reduction in this risk of this outcome (HR, .42; P = .007).

No new toxicities or emergent symptoms were noted from extending AI therapy, according to Dr. Goss. However, the letrozole group significantly more commonly experienced bone pain (18% vs. 14%), bone fractures (14% vs. 9%), and new-onset osteoporosis (11% vs. 6%). Therefore, “bone health remains important for risk-benefit consideration,” he said.

Patient-reported outcomes

In a separate session and the press briefing, Dr. Julie Lemieux, a researcher at the Centre Hospitalier affilié Universitaire de Québec, reported the trial’s patient-reported outcomes, ascertained from questionnaires completed at baseline and annually out to 5 years.

In general, both the letrozole and placebo groups had small deteriorations over time in global quality of life as assessed from summary scores on the mental and physical scales of the 36-item Short Form Health Survey (SF-36). But both also had small improvements over time in scores on the Menopause-Specific Quality of Life (MENQOL) scale.

When compared, the two groups were statistically indistinguishable on most of these measures. The only significant difference was greater worsening in the letrozole group on the role function-physical subscale of the SF-36, which pertains to difficulty performing work or physical activity due to physical health. However, the difference averaged just 3.2 points, which fell short of the 5 points that the investigators considered clinically important.

“The limitation of this analysis was that it was a highly selected population. All of these women had already tolerated 5 years of an aromatase inhibitor, and about 70% had received 5 years of tamoxifen before,” Dr. Lemieux commented. “Also, they were clinical trial participants.”

Nonetheless, these findings “are very reassuring for those women who want a longer duration of adjuvant endocrine therapy that they can expect a preserved quality of life,” she concluded.

Dr. Goss disclosed that he had no relevant conflicts of interest. Dr. Lemieux disclosed that she had no relevant conflicts of interest. The trial received support from Novartis.

CHICAGO – Extending adjuvant aromatase inhibitor (AI) therapy from 5 years to 10 years further reduces the risk of recurrence and new breast cancer in postmenopausal women treated for early disease, according to findings of the MA17.R trial.

In the phase III trial conducted by the Canadian Cancer Trials Group and the North American Breast Cancer Group, 1,918 postmenopausal women who had completed about 5 years of AI therapy (preceded by tamoxifen in the majority of cases) were randomized to take the AI letrozole or to stop therapy by taking placebo for an additional 5 years.

Compared with peers who stopped, women who continued AI therapy for 5 more years had a 34% lower risk of recurrence or contralateral breast cancer, investigators reported in sessions and a press briefing at the annual meeting of the American Society of Clinical Oncology. The trade-off was a small increase in the rates of skeletal adverse events such as fractures; quality of life was essentially unaffected.

“MA17.R is the first study to show the benefit of extending an adjuvant aromatase inhibitor beyond 5 years,” commented lead investigator Paul E. Goss, M.D., director of the Breast Cancer Research Program at the Massachusetts General Hospital and a professor of medicine at Harvard Medical School, both in Boston. “Unlike many anticancer therapies, aromatase inhibitors are readily accessible around the world, and therefore, our results will further improve the outcome of many women with breast cancer.”

The disease-free survival curves will likely separate further, given a “legacy effect” of endocrine therapy that persists after it ends, he predicted. “And I think overall survival will eventually become positive in MA.17R. … The Food and Drug Administration has taken the opinion that overall survival follows disease-free survival like night follows day for endocrine therapies, and I think they are correct, I think that’s what we see in all the trials.”

Implications

It remains unclear how patients should be managed after 10 years of an AI, according to Dr. Goss. “That’s uncharted waters,” he elaborated. “We know from the curve of the natural history of this disease that it chronically relapses, and we continue to see patients 25 years after their primary diagnosis with a recurrence.” Some data in mice suggest there may be benefit from continuing the AI until recurrence. “I don’t think that would be entered into in clinical practice as a rule, because there is no clinical trial of that,” he said. “But this data will now take the aromatase inhibitors out to 10 years.”

The MA.17R trial’s findings show that extended duration of AI therapy is “clinically valuable,” according to ASCO expert Harold J. Burstein, M.D., Ph.D., a senior physician at the Dana-Farber Cancer Institute and an associate professor of medicine at the Harvard Medical School in Boston. He predicted the findings will have at least two consequences.

NEW ORLEANS – Recurrent episodes of diabetic ketoacidosis (DKA) resulted in altered brain metabolite concentration, as well as differences in mental processing speed, compared with healthy controls, judging from the results from a small pilot study.

While previous work examining the relationship of DKA to cognition and neural structure has focused upon children and adolescents, researchers at Emory University and the Georgia Institute of Technology, both in Atlanta, set out of evaluate for the first time acute neuroanatomical and cognitive changes in adult patients with first and recurrent episodes of DKA. In an interview in advance of the annual scientific sessions of the American Diabetes Association, one of the researchers, Gilda E. Ennis, Ph.D., said that DKA is the most serious diabetic emergency in patients with type 1 and 2 diabetes and results in an estimated health care cost of $2.4 billion annually. “While we know that one of the major precipitating causes of DKA in adult patients is poor adherence to insulin therapy, we do not understand why patients are noncompliant,” said Dr. Ennis, who is a postdoctoral fellow in the Georgia Institute of Technology’s school of psychology.

She and her associates conducted a pilot study examining advanced MRI metrics and cognitive measures 72 hours after resolution of DKA in 10 patients with a first episode of DKA and 11 patients with three or more episodes of DKA. The same MRI and cognitive measures were collected from 10 healthy controls and 10 patients with type 1 diabetes and no history of DKA.

MRI spectroscopy revealed reduced N-acetylaspartate concentrations in diabetes patients with multiple episodes of DKA, compared with healthy controls, but no significant differences were seen between diabetes patients with and without DKA. Cognitive testing revealed that patients with recurrent DKA had significantly worse processing speed, compared with healthy controls (P = .02), while processing speed deficits in patients with a single DKA and those with diabetes and no DKA was intermediate between healthy controls and those with recurrent DKA.

“We were surprised to find significant cognitive and neural deficits in the recurrent DKA group relative to healthy controls in such a small sample,” Dr. Ennis said. “This suggests that statistical differences in cognition and neural structure between patients with recurrent DKA and healthy controls may be large. We found that recurrent DKA was associated with significant deficits in processing speed and memory, decreases in right putamen volume, regionally decreased white matter integrity, and altered brain metabolite concentrations, suggestive of CNS inflammatory changes and neuronal injury.”

The findings may explain the high rates of medication noncompliance commonly seen in this patient population. “If this proposition is true, conventional education and standard care approaches to the treatment of type 1 diabetes, especially in patients with a history of DKA, may need to change,” she said. “Strategies to improve insulin adherence may require a special insulin compliance intervention that includes persistent medication adherence reminders, such as text messaging and nurse-telephone follow-up.”

Dr. Ennis acknowledged that the findings require replication in a prospective longitudinal study with a larger sample size. “It will be important to determine if acute neuroanatomical and cognitive deficits in patients with recurrent DKA persist over time,” she said. “Duration of type 1 diabetes could produce similar findings and would need to be controlled in future research.” She reported having no financial disclosures.

NATIONAL HARBOR, MD. – Delayed-release dimethyl fumarate (DMF) coadministered with norgestimate/ethinyl estradiol, a commonly used progesterone-estrogen combination oral contraceptive, did not alter the OC’s pharmacokinetics or pharmacodynamics, according to the results of a small study.

The safety profile of the coadministered preparation is similar to the profile of DMF (Tecfidera, Biogen) alone, Dr. Bing Zhu said in a poster session at the annual meeting of the Consortium of Multiple Sclerosis Centers.

The findings indicate that women with relapsing-remitting multiple sclerosis (RRMS) who are of childbearing age and who are being treated with DMF can use OCs without having to modify the contraceptive dose, said Dr. Zhu, who is an employee of Biogen, Cambridge, Mass.

The study involved healthy women aged 18-45 years (mean age about 31 years) who were able to conceive. All received a daily OC (Ortho-Cyclen; 250 mcg norgestimate, 35 mcg ethinyl estradiol). After 28 days, those with progesterone levels less than 3 ng/mL were randomized to a 28-day regimen of either the daily dose of OC (n = 39) or OC along with DMF (240 mg twice daily), designated period 1, with crossover to the other treatment for a further 28 days (period 2). Blood samples were collected during the first 24 hours for pharmacokinetic measurements and at 2, 3, and 4 weeks for pharmacodynamic determinations.

The primary objective was the pharmacokinetics of norgestimate, as determined by measuring the levels of its main metabolite, norelgestromin. Secondary objectives included pharmacodynamics, as determined by the levels of serum progesterone and the safety/tolerability of DMF.

Plasma concentrations of norelgestromin and ethinyl estradiol were identical over time in the OC and OC + DMF groups in period 1, as was serum progesterone.

Treatment-emergent adverse events were similar in type and severity in both groups. Most were mild. The prevalent adverse events included flushing and gastrointestinal disorders accompanied by nausea and vomiting. Adverse events occurred in 10 of the 39 (26%) subjects who received the OC and in 26 of the 39 (67%) subjects who received the OC + DMF. Discontinuation because of adverse events occurred in 8% and 15% of subjects who received the OC and the OC + DMF, respectively. There were no deaths.

“The results suggest that women of childbearing potential treated with DMF are able to use a combined OC for contraception without dose modification,” said Dr. Zhu.

The study findings were recently published (Neurology. 2016 Apr 5;86:Suppl P2.097).

The study was funded by Biogen. Dr. Zhu is a Biogen employee.

NATIONAL HARBOR, MD. – Delayed-release dimethyl fumarate (DMF) coadministered with norgestimate/ethinyl estradiol, a commonly used progesterone-estrogen combination oral contraceptive, did not alter the OC’s pharmacokinetics or pharmacodynamics, according to the results of a small study.

The safety profile of the coadministered preparation is similar to the profile of DMF (Tecfidera, Biogen) alone, Dr. Bing Zhu said in a poster session at the annual meeting of the Consortium of Multiple Sclerosis Centers.

The findings indicate that women with relapsing-remitting multiple sclerosis (RRMS) who are of childbearing age and who are being treated with DMF can use OCs without having to modify the contraceptive dose, said Dr. Zhu, who is an employee of Biogen, Cambridge, Mass.

The study involved healthy women aged 18-45 years (mean age about 31 years) who were able to conceive. All received a daily OC (Ortho-Cyclen; 250 mcg norgestimate, 35 mcg ethinyl estradiol). After 28 days, those with progesterone levels less than 3 ng/mL were randomized to a 28-day regimen of either the daily dose of OC (n = 39) or OC along with DMF (240 mg twice daily), designated period 1, with crossover to the other treatment for a further 28 days (period 2). Blood samples were collected during the first 24 hours for pharmacokinetic measurements and at 2, 3, and 4 weeks for pharmacodynamic determinations.

The primary objective was the pharmacokinetics of norgestimate, as determined by measuring the levels of its main metabolite, norelgestromin. Secondary objectives included pharmacodynamics, as determined by the levels of serum progesterone and the safety/tolerability of DMF.

Plasma concentrations of norelgestromin and ethinyl estradiol were identical over time in the OC and OC + DMF groups in period 1, as was serum progesterone.

Treatment-emergent adverse events were similar in type and severity in both groups. Most were mild. The prevalent adverse events included flushing and gastrointestinal disorders accompanied by nausea and vomiting. Adverse events occurred in 10 of the 39 (26%) subjects who received the OC and in 26 of the 39 (67%) subjects who received the OC + DMF. Discontinuation because of adverse events occurred in 8% and 15% of subjects who received the OC and the OC + DMF, respectively. There were no deaths.

“The results suggest that women of childbearing potential treated with DMF are able to use a combined OC for contraception without dose modification,” said Dr. Zhu.

The study findings were recently published (Neurology. 2016 Apr 5;86:Suppl P2.097).

NEW ORLEANS – In the first known controlled study of its kind, researchers demonstrated the reliability of trained dogs to alert hypoglycemia in human companions with type 1 diabetes, but at the cost of a high false-positive rate, compared with continuous glucose monitoring.

“The use of trained dogs to alert to changes in blood glucose in human companions with diabetes is increasing yet we don’t know how effective they are,” lead author Dr. Evan Los said in an interview in advance of the annual scientific sessions of the American Diabetes Association. “Enthusiastic anecdotal reports and limited in vitro studies are promising but rigorous studies have not been done. Clinicians are unable to provide informed advice when patients ask, ‘What do you think about diabetes alert dogs?’”

Dr. Los, a pediatric endocrinology fellow at Oregon Health and Science University, Portland, and his associates set out to conduct a controlled study of the reliability of diabetes alert dogs to detect hypoglycemia in their human companions with type 1 diabetes under real-life conditions. Capillary blood glucose (CBG) and continuous glucose monitoring (CGM) were used as comparators, and the study participants consisted of eight dog-human pairs. The human subjects ranged in age from 4 to 48 years old. Hypoglycemia was defined as CBG and/or CGM below 70 mg/dL and the human subjects answered survey questions regarding their impressions of the dog’s reliability and reasons for obtaining a diabetes alert dog. A timely alert was defined as occurring within 10 minutes before to 30 minutes after onset of hypoglycemia.

On a 10-point Likert scale, the dog users reported being “very satisfied” and “largely confident” in their dog’s ability to detect hypoglycemia (scores of 8.9 and 7.9, respectively), and they universally cited detection of hypoglycemia as the chief reason for obtaining a trained service dog. The researchers found that spontaneous dog alerts occurred 3.2 times more often than the rate of alerts during euglycemia, which was defined as 70-180 mg/dL, but the positive predictive value of dog alerts for hypoglycemia was only 12%. When Dr. Los and his associates reviewed event diaries and blinded CGM data, they observed that trained dogs provided a timely alert in 36% of all 45 hypoglycemia events. In the 30 events when both the dog-alerted and the blinded-CGM reached the hypoglycemia threshold, CGM would have alerted prior to the dog in 73% of events, which translated into a median difference of 22 minutes sooner.

“Trained dogs often alert a human companion to otherwise unknown hypoglycemia,” Dr. Los said. “However, due to high false-positive rates, a dog alert alone is unlikely to be helpful in differentiating hypo-/hyper-/euglycemia. CGM often detects hypoglycemia before a trained dog by a clinically significant margin.”

He acknowledged the study’s small sample size as a limitation. “Dog breeds and training methods were not universal, so there are likely to be variation in the reliability between dogs,” Dr. Los added. “This is not the final word on whether trained dogs might be helpful for patients with diabetes and there may be other benefits not assessed by this study such as having a positive partner in the daily management of a chronic disease.” He reported having no financial disclosures.

LONDON – The new EULAR recommendations for fibromyalgia incorporate a decade’s worth of new evidence collected since the last edition appeared in 2008.

Although the 2016 recommendations do not reflect a novel understanding of the pathophysiology of fibromyalgia or a radically different approach to managing the disease, compared with those published in 2008, they differ vastly in the level and quality of supporting evidence behind them, said Dr. Gary J. Macfarlane, convener of the fibromyalgia recommendations panel and clinical professor of epidemiology at the University of Aberdeen, Scotland.

Mitchel L. Zoler/Frontline Medical News

Dr. Macfarlane said that the past decade has seen “an explosion of evidence from randomized trials” around the management of fibromyalgia. “I think this will be one of the first EULAR guidelines in which all the recommendations are going to be based on systematic reviews or meta-analysis” – 107 altogether, he said in an interview.

Fibromyalgia – a heterogeneous pain condition that involves abnormal pain processing and can affect sleep, function, and quality of life – can be complex to diagnose and treat. Pain is a signature feature of fibromyalgia, but it is not the only treatment target: sleep, ability to function, and quality of life all are important, Dr. Macfarlane said.

The guidelines emphasize that optimal management of fibromyalgia requires not just a prompt diagnosis but “a comprehensive assessment of the patient’s ability to function and about the psychosocial context in which symptoms occur,” he said.

Patient education, including written information, is key and is the first step in management. Initial management should focus on nonpharmacologic interventions, specifically exercise. In patients for whom educational materials alone are insufficient to provide benefit, the next step is enrollment of the patient into a physical therapy program that involves an individualized program of graded physical exercise. Other nonpharmacologic interventions that can be introduced at this stage include hydrotherapy and acupuncture.

If there is insufficient response to these first two intervention steps, the next phase should start with a second round of patient assessment to develop an individualized intervention program. This involves characterizing the dominant features of the patient’s complaints into one of the three main categories: pain-related depression and anxiety, or behavior indicating abnormal coping strategies; severe pain, sleep disturbance, or both; or severe disability or sick leave, Dr. Macfarlane said at the European Congress of Rheumatology.

For patients in the first subgroup – pain-related depression and anxiety, or behavior indicating abnormal coping strategies – the intervention should consist of psychological therapies, primarily cognitive-behavioral therapy (CBT). For patients with more severe depression or anxiety, psychopharmacologic treatment is also an option.

For patients in the second subgroup – those with severe pain, sleep disturbance, or both – the main intervention is pharmacotherapy. For severe pain, this can involve duloxetine, pregabalin, or tramadol either alone or in combination with paracetamol (acetaminophen). For sleep disturbance, recommended drug interventions are low-dose amitriptyline, cyclobenzaprine, or pregabalin administered at bedtime.

For patients in the third subgroup – with severe disability or sick leave – the recommended intervention is a multimodal rehabilitation program.

“We made the decision to consider all therapies whether they were licensed in Europe or not because we felt that helps to contribute to the debate,” Dr. Macfarlane said. He also highlighted several interventions that have been proposed in the past, but which his working group refrained from recommending because of either lack of demonstrated effectiveness or the poor quality of the studies that appeared to document efficacy. These nonrecommended interventions are biofeedback, capsaicin, hypnotherapy, massage, S-adenosyl methinone or SAMe, and other complementary and alternative therapies.

Dr. Macfarlane noted that, despite a decade’s worth of findings, many questions still hover over the ideal management of fibromyalgia. Although the guidelines strongly promote exercise, “we still don’t have enough information about what specific type of exercise would be most beneficial.”

And while studies show overwhelmingly that CBT is effective, the size of the benefit is modest. Dr. Macfarlane said that it will be important to learn whether combined pharmacologic and nonpharmacologic approaches might be more effective from the get-go for certain patients – in contrast to the stepped approach outlined in the guidelines – and whether there is a way to identify patients for whom such interventions as CBT are most likely to be effective.

Another question still unanswered is whether fibromyalgia should remain primarily the domain of rheumatologists. While this was not a question addressed in the guidelines, the writing committee involved not only rheumatologists but also specialists in pain, internal medicine, occupational health, and nursing – underscoring the multidisciplinary direction that fibromyalgia treatment is taking.

“I think rheumatologists have an important role to play because pain is a dominant feature and because fibromyalgia is often comorbid with inflammatory rheumatic conditions,” Dr. Macfarlane said. “But I think we should be looking at other models of care for these patients as well.”

Because patients are referred in and out of various specialties, “there is no one really looking at the overall management, thinking about them holistically,” he said. “There’s a need for us to organize health care services better, so when we have a patient with fibromyalgia-like symptoms, we manage their journey through the system effectively instead of ping-ponging them around.”

Dr. Macfarlane has given lectures on behalf of Janssen and has received research support from Pfizer.

MINNEAPOLIS – Can telehealth help obese patients lose weight?

Weight management experts at the Medical University of South Carolina, Charleston, sought to find out through a unique program to provide practice support to rural health care providers.

The telehealth program gives health clinics in rural South Carolina access to teams of weight management experts and support through mHealth applications linking providers and clinical faculty.

The project includes biweekly group patient sessions led by a psychologist, registered dietitian, and exercise physiologist. The program uses videoconferencing systems and a provider-focused mobile app that captures weight and blood pressure data from wireless peripherals, while allowing for manual input of data.

In a video interview at the American Telemedicine Association annual conference, Ragan Aleise DuBose-Morris, Ph.D., director of telehealth education for the Medical University of South Carolina, and Joshua Brown, Ph.D., director of clinical services at the university’s Weight Management Center, discussed the weight management initiative and its effectiveness. Dr. DuBose-Morris and Dr. Brown also explained how the initiative was designed, and how the effort has impacted the weight of obese patients in the state.

CHICAGO – A simple Web-based mobile application (web-app) improved survival time and quality of life of patients with advanced lung cancer, according to a randomized study presented at the annual meeting of the American Society of Clinical Oncology.

The study was stopped at the planned interim survival analysis that occurred after 121 evaluable patients because of survival benefit favoring the web-app arm. The application, called Moovcare, allowed patients to report symptoms over time and stay in close touch with their care providers after their initial surgery, chemotherapy, or radiation therapy.

“The 1-year survival was 75% in the Moovcare vs. 49% in the control arm,” said lead author Dr. Fabrice Denis of the Institut Inter-régional de Cancérologie Jean Bernard in LeMans, France, in a press conference.

Dr. Denis identified several reasons why a web-app could be useful in treating patients with lung cancer. Even with more than 1 million lung cancer deaths a year worldwide, there is no standard follow-up, and relapses do not occur on a 3 or 6-month schedule of planned visits. So patients often wait several weeks until their next visit to report symptoms indicative of a relapse. They may also be reluctant to report symptoms because of shame over how they contracted the disease, for example, from smoking. And patients are often hesitant to “bother” the doctor with symptoms between visits. All these reasons can contribute to suboptimal therapy and worse outcomes.

Investigators designed Moovcare to allow patients to report symptoms weekly, facilitating early detection of relapse or dangerous medical conditions and triggering early supportive care. They compared the web-app to a control of usual, nonpersonalized follow-up in a French multicenter prospective, randomized trial.

Patients (n = 121) with stage II/node-positive to stage IV (90% stage III/IV) nonprogressive small cell or non–small cell lung cancer were randomly assigned 1:1 to the two arms of the trial. They had to have Internet access, prior experience with email, performance status of 0-2, and an initial symptom score less than 7. Patients could be taking tyrosine kinase inhibitors or on maintenance therapy. Monitoring visits were the same for both groups every 3 months or more frequently. Patients in the control arm received more frequent computed tomographic (CT) imaging than did ones in the web-app arm, and CT scans could be performed at any time in either group based on the investigator’s clinical judgment, or in the case of the web-app, as suggested by patient report in the algorithm.

The median follow up was 9 months. Relapse rates were close to 50% for both groups. The 1-year survival of 75% in the Moovcare to 49% in the control arm gave a 1-year absolute survival increase of 26%. Median survival was 19 months vs. 12 months, a 7-month improvement in median survival for the Moovcare arm. The hazard ratio for death in the web-app arm, compared with the control arm was 0.325 (95% confidence interval, 0.157-0.672; P = .0025).

When they relapsed, 77% of patients in the web-app arm had a good performance status, compared with 33% in the control arm. “This led to 74% of patients receiving optimal therapy in the Moovcare arm vs. 33% in the control arm,” Dr. Denis said. “And the number of imaging [procedures] was reduced by 50% per patient per year.”

Overall quality of life was better in the web-app arm, as assessed using standard quality of life questionnaires.

Moovcare works by having patients or their relatives report 12 symptoms weekly (for example, asthenia, cough, dyspnea, anorexia, etc.) using a smartphone, tablet, or computer. An algorithm analyzes an association of symptoms and triggers email alerts to health care providers if relapse or dangerous medical conditions may be occurring. Providers follow up alerts by phone and schedule visits and imaging. “The sensitivity of the algorithm was high and was validated in two prospective studies,” Dr. Denis said. Sensitivity was 86%-100%.

Moovcare allowed earlier detection of relapse and improved overall survival for three reasons. “It allowed higher performance status at relapse, leading to more optimal therapy for relapsing patients. Dangerous medical conditions were detected earlier and treated earlier. It favored earlier supportive care, which improved quality of life. Less imaging was needed and performed at the right time,” Dr. Denis said.

Patients were monitored on a weekly basis, allowing more personalized care. The Moovcare web-app has been evaluated prospectively in about 300 patients, providing a high level of evidence of its utility in improving outcomes for patients with advanced lung cancer.

Press conference moderator Dr. Patricia Ganz commented that Moovcare is an example of a new way to improve the delivery of high-quality care to patients. “If we had a drug or some new intervention that caused this level of survival benefit, wouldn’t we want to go out and use it?” she asked. “This is a tremendous advance. This is personalized medicine. This is really tailoring it to the patient, and you can see how simple it is to collect this kind of data from the patient and then bring them in in between what would have been a scheduled visit.” She said the app overcomes the barrier of patients putting off reporting symptoms until their next visit or their reluctance to “bother the doctor.”

She said the app alerts the health care team to potential problems and prompts them to “use tests when appropriate, not on a schedule, [which] leads to avoidance of waste in the follow-up of care of our patients.”

CHICAGO – A simple Web-based mobile application (web-app) improved survival time and quality of life of patients with advanced lung cancer, according to a randomized study presented at the annual meeting of the American Society of Clinical Oncology.

The study was stopped at the planned interim survival analysis that occurred after 121 evaluable patients because of survival benefit favoring the web-app arm. The application, called Moovcare, allowed patients to report symptoms over time and stay in close touch with their care providers after their initial surgery, chemotherapy, or radiation therapy.

“The 1-year survival was 75% in the Moovcare vs. 49% in the control arm,” said lead author Dr. Fabrice Denis of the Institut Inter-régional de Cancérologie Jean Bernard in LeMans, France, in a press conference.

Dr. Denis identified several reasons why a web-app could be useful in treating patients with lung cancer. Even with more than 1 million lung cancer deaths a year worldwide, there is no standard follow-up, and relapses do not occur on a 3 or 6-month schedule of planned visits. So patients often wait several weeks until their next visit to report symptoms indicative of a relapse. They may also be reluctant to report symptoms because of shame over how they contracted the disease, for example, from smoking. And patients are often hesitant to “bother” the doctor with symptoms between visits. All these reasons can contribute to suboptimal therapy and worse outcomes.

Investigators designed Moovcare to allow patients to report symptoms weekly, facilitating early detection of relapse or dangerous medical conditions and triggering early supportive care. They compared the web-app to a control of usual, nonpersonalized follow-up in a French multicenter prospective, randomized trial.

Patients (n = 121) with stage II/node-positive to stage IV (90% stage III/IV) nonprogressive small cell or non–small cell lung cancer were randomly assigned 1:1 to the two arms of the trial. They had to have Internet access, prior experience with email, performance status of 0-2, and an initial symptom score less than 7. Patients could be taking tyrosine kinase inhibitors or on maintenance therapy. Monitoring visits were the same for both groups every 3 months or more frequently. Patients in the control arm received more frequent computed tomographic (CT) imaging than did ones in the web-app arm, and CT scans could be performed at any time in either group based on the investigator’s clinical judgment, or in the case of the web-app, as suggested by patient report in the algorithm.

The median follow up was 9 months. Relapse rates were close to 50% for both groups. The 1-year survival of 75% in the Moovcare to 49% in the control arm gave a 1-year absolute survival increase of 26%. Median survival was 19 months vs. 12 months, a 7-month improvement in median survival for the Moovcare arm. The hazard ratio for death in the web-app arm, compared with the control arm was 0.325 (95% confidence interval, 0.157-0.672; P = .0025).

When they relapsed, 77% of patients in the web-app arm had a good performance status, compared with 33% in the control arm. “This led to 74% of patients receiving optimal therapy in the Moovcare arm vs. 33% in the control arm,” Dr. Denis said. “And the number of imaging [procedures] was reduced by 50% per patient per year.”
