Do not rely on more traditional signs and symptoms of COVID-19 like fever and dyspnea when assessing patients with Cushing’s syndrome for the novel coronavirus, Rosario Pivonello, MD, PhD, and colleagues urged.

Physicians evaluating patients with Cushing’s syndrome for COVID-19 “should be suspicious of any change in health status of their patients with Cushing’s syndrome, rather than relying on fever and [dyspnea] as typical features,” Dr. Pivonello, an endocrinologist with the University of Naples (Italy) Federico II, and colleagues wrote in a commentary published in The Lancet Diabetes & Endocrinology.

COVID-19 symptoms are a unique concern among patients with Cushing’s syndrome because many of the cardiometabolic and immune impairments that place someone at higher risk of more severe disease or mortality for the novel coronavirus – such as obesity, hypertension, diabetes, and immunodeficiency syndromes – are also shared with Cushing’s syndrome.

Increased cardiovascular risk factors and susceptibility to severe infection are “two leading causes of death” for patients with Cushing’s syndrome, Dr. Pivonello and colleagues noted.

The immunocompromised state of patients with Cushing’s syndrome may make detection of COVID-19 infection difficult, the authors say. For example, fever is a common symptom of patients with COVID-19, but in patients with active Cushing’s syndrome, “low-grade chronic inflammation and the poor immune response might limit febrile response in the early phase of infection,” Dr. Pivonello and colleagues wrote.

In other cases, because Cushing’s syndrome and COVID-19 have overlapping symptoms, it may be difficult to attribute a particular symptom to either disease. Dyspnea is a common symptom of COVID-19, but may present in Cushing’s syndrome because of “cardiac insufficiency or weakness of respiratory muscles,” the authors wrote. Instead, physicians should look to other COVID-19 symptoms, such as cough, dysgeusia, anosmia, and diarrhea, for signs of the disease.

Patients with Cushing’s syndrome may also be predisposed to a more severe course of COVID-19 because of the prevalence of obesity, hypertension, or diabetes in these patients, which have been identified as comorbidities that increase the likelihood of severe COVID-19 and progression to acute respiratory distress syndrome (ARDS). “However, a key element in the development of ARDS during COVID-19 is the exaggerated cellular response induced by the cytokine increase, leading to massive alveolar–capillary wall damage and a decline in gas exchange,” Dr. Pivonello and colleagues wrote. “Because patients with Cushing’s syndrome might not mount a normal cytokine response, these patients might [paradoxically] be less prone to develop severe ARDS with COVID-19.”

As both Cushing’s syndrome and COVID-19 are associated with hypercoagulability, the authors “strongly advise” using low-molecular-weight heparin in hospitalized patients with active Cushing’s syndrome who develop COVID-19. In both diseases, there is also a risk of longer duration of viral infections and opportunistic infections such as atypical bacterial and invasive fungal infections. For this reason, the authors also recommended patients with Cushing’s syndrome who have COVID-19 be placed on prolonged antiviral and broad-spectrum antibiotic treatment as a prophylactic measure.

During the pandemic, avoiding surgery for Cushing’s syndrome should be considered to reduce the likelihood of acquiring COVID-19 in a hospital setting, the authors wrote. Medical therapy can be temporarily used where appropriate, such as using ketoconazole, metyrapone, osilodrostat, and etomidate to lower cortisol levels. They acknowledge that some cases of malignant Cushing’s syndrome may require “expeditious definitive diagnosis and proper surgical resolution.”

After remission, while infection risk should be significantly lowered, other comorbidities like obesity, hypertension, diabetes, and thromboembolic diathesis may remain. “Because these are features associated with an increased death risk in patients with COVID-19, patients with Cushing’s syndrome in remission should be considered a high-risk population and consequently adopt adequate self-protection strategies to [minimize] contagion risk,” the authors wrote.

Two European prospective case series published in JAMA Dermatology found no direct association between skin lesions on the hands and feet and SARS-CoV-2 in young people, which raises questions about other contributing factors, such as lockdown conditions, which may be clarified with additional research.

Lindy P. Fox, MD, professor of dermatology at the University of California, San Francisco, who was not an author of either study, urged caution in interpreting these results. Data from the American Academy of Dermatology and a recent paper from the British Journal of Dermatology suggest a real association exists, at in least some patients. “It’s going to be true that most patients with toe lesions are PCR [polymerase chain reaction]-negative because it tends to be a late phenomenon when patients are no longer shedding virus,” Dr. Fox said in an interview.

Reports about chickenpox-like vesicles, urticaria, and other skin lesions in SARS-CoV-2 patients have circulated in the clinical literature and the media. Acute acro-ischemia has been cited as a potential sign of infection in adolescents and children.

One of the European studies, which was published in JAMA Dermatology, explored this association in 20 patients aged 1-18 years (mean age, 12.3 years), who presented with new-onset acral inflammatory lesions in their hands and feet at La Fe University Hospital, in Valencia, during the country’s peak quarantine period in April. Investigators conducted blood tests and reverse transcriptase–PCR (RT-PCR) for SARS-CoV-2, and six patients had skin biopsies.

Juncal Roca-Ginés, MD, of the department of dermatology, at the Hospital Universitario y Politécnico in La Fe, and coauthors, identified acral erythema in 6 (30%) of the cases, dactylitis in 4 (20%), purpuric maculopapules in 7 (35%), and a mixed pattern in 3 (15%). Serologic and viral testing yielded no positive results for SARS-CoV-2 or other viruses, and none of the patients exhibited COVID-19 symptoms such as fever, dry cough, sore throat, myalgia, or taste or smell disorders. In other findings, 45% of the patients had a history of vascular reactive disease of the hands, and 75% reported walking barefoot in their homes while staying at home. Only two patients reported taking medications.

In the six patients who had a biopsy, the findings were characteristic of chillblains, “confirming the clinical impression,” the authors wrote. Concluding that they could not show a relationship between acute acral skin changes and COVID-19, they noted that “other studies with improved microbiologic tests or molecular techniques aimed at demonstrating the presence of SARS-CoV-2 in the skin may help to clarify this problem.”

The other case series, which was also published in JAMA Dermatology and included 31 adults at a hospital in Brussels, who had recently developed chillblains, also looked for a connection between SARS-CoV-2 and chilblains, in April. Most of the participants were in their teens or 20s. Lesions had appeared on hands, feet, or on both extremities within 1-30 days of consultation, presenting as erythematous or purplish erythematous macules, occasionally with central vesicular or bullous lesions or necrotic areas. Patients reported pain, burning, and itching.

Skin biopsies were obtained in 22 patients and confirmed the diagnosis of chilblains; of the 15 with immunofluorescence analyses, 7 patients were found to have vasculitis of small-diameter vessels.

Of the 31 patients, 20 (64%) reported mild symptoms consistent with SARS-CoV-2, yet none of the RT-PCR or serologic test results showed signs of the virus in all 31 patients. “Because some patients had experienced chilblains for more than 15 days [under 30 days or less] at the time of inclusion, we can reasonably exclude the possibility that serologic testing was done too soon,” observed the authors. They also didn’t find eosinopenia, lymphopenia, and hyperferritinemia, which have been associated with COVID-19, they added.

Changes in lifestyle conditions during the pandemic may explain the appearance of these lesions, according to the authors of both studies, who mentioned that walking around in socks or bare feet and reduced physical activity could have indirectly led to the development of skin lesions.

It’s also possible that young people have less severe disease and a delayed reaction to the virus, Ignacio Torres-Navarro, MD, a dermatologist with La Fe University and the Spanish study’s corresponding author, said in an interview. Their feet may lack maturity in neurovascular regulation and/or the eccrine glands, which can happen in other diseases such as neutrophilic idiopathic eccrine hidradenitis. “In this context, perhaps there was an observational bias of the parents to the children when this manifestation was reported in the media. However, nothing has been demonstrated,” he said.

In an accompanying editor’s note, Claudia Hernandez, MD, of the departments of dermatology and pediatrics, Rush University Medical Center, Chicago, and Anna L. Bruckner, MD, of the departments of dermatology and pediatrics at the University of Colorado, Aurora, wrote that “it is still unclear whether a viral cytopathic process vs a viral reaction pattern or other mechanism is responsible for ‘COVID toes.’ ” Lack of confirmatory testing and reliance on indirect evidence of infection complicates this further, they noted, adding that “dermatologists must be aware of the protean cutaneous findings that are possibly associated with COVID-19, even if our understanding of their origins remains incomplete.”

In an interview, Dr. Fox, a member of the AAD’s’s COVID-19 Registry task force, offered other possible reasons for the negative antibody tests in the studies. The assay might not have been testing the correct antigen, or the timing of the test might not have been optimal. “More studies will help this become less controversial,” she said.

The authors of the two case series acknowledged potential limitations of their studies. Neither was large in scope: Both took place over a week’s time and included small cohorts. The Belgian study had no control group or long-term follow-up. Little is still known about the clinical manifestations and detection methods for SARS-CoV-2, noted the authors of the Spanish study.

The Spanish study received funding La Fe University Hospital’s department of dermatology, and the authors had no disclosures. The Belgian study received support from the Fondation Saint-Luc, which provided academic funding for its lead author, Marie Baeck, MD, PhD. Another author of this study received personal fees from the Fondation Saint-Luc and personal fees and nonfinancial support from Bioderma. The authors of the editor’s note had no disclosures.

Topline results show positive results for the experimental intranasal nalmefene product OX125 for opioid overdose reversal, Orexo, the drug’s manufacturer, announced on June 30.

A crossover, comparative bioavailability study was conducted in healthy volunteers to assess nalmefene absorption of three development formulations of OX125. Preliminary results showed “extensive and rapid absorption” across all three formulations versus an intramuscular injection of nalmefene, Orexo reported.

“As the U.S. heroin crisis has developed to a fentanyl crisis, the medical need for novel and more powerful opioid rescue medications is vast,” Nikolaj Sørensen, president and CEO of Orexo, said in a press release.

“The need has also escalated due to the COVID-19 pandemic as the consequences of social distancing and economic weakness are expected to lead to a significant increase in mental health issues and substance use disorders,” Mr. Sørensen added.

Robert Rönn, vice president and head of research and development at Orexo, noted in the same release that the company will now be working with the Food and Drug Administration “to identify the optimal route to market.”

There were more than 31,000 fatalities from highly potent synthetic opioids in the United States in 2018, the manufacturer reported. “Like naloxone, nalmefene is an opioid antagonist that acts by blocking the effects of opioids at the opioid receptors.”

However, nalmefene has a longer half-life than naloxone. These longer-acting properties may be “of particular value to protect against renarcotization (second overdose), as the antagonist wears off,” according to an Orexo press release.

OX125 was developed to provide absorption of drug substances through the nasal mucosa.

In addition to showing rapid absorption across all formulations studied, study results showed “good tolerability, supporting the viability” of the treatment as an opioid overdose rescue medication, the company said.

“This is not only a proof of concept for our wholly owned OX125 product, but also a demonstration of the value of our novel nasal technology platform,” Mr. Rönn said.

“Alongside OX124, our naloxone rescue project, OX125 will be an important lifesaving addition in our commitment to helping patients suffering from opioid addiction in all phases,” Mr. Sørensen added.

The oral selective estrogen receptor degrader (SERD) LSZ102 plus either ribociclib or alpelisib shows manageable safety and encouraging clinical activity in heavily pretreated estrogen receptor (ER)–positive breast cancer patients who progressed after prior endocrine therapy, according to interim results of an open-label phase 1/1b study.

The effects seen in the study, which is the first to report on an oral SERD in combination with both CDK4/6 and PI3Ka inhibitors, occurred regardless of ESR1 and PIK3CA mutations, said Komal Jhaveri, MD, of Memorial Sloan Kettering Cancer Center in New York.

Dr. Jhaveri reported the results at the European Society of Medical Oncology: Breast Cancer virtual meeting.

The overall response rate (ORR) among 78 patients enrolled in an LSZ102 monotherapy arm (arm A) was 1.3%, and the progression-free survival (PFS) was 1.8 months. The clinical benefit rate (CBR) was 9.1%.

Among 76 patients enrolled in an LSZ102+ribociclib arm (arm B), the ORR was 15.8%, the PFS was 6.2 months, and the CBR was 35.5%.

Among the 39 patients enrolled in an LSZ102+alpelisib arm (arm C), the ORR was 5.4%, the PFS was 3.5 months, and the CBR was 18.9%.

After the data cutoff, one additional partial response (PR) was reported in arm C, Dr. Jhaveri said, noting that two of three confirmed responses were in known PIKC3A-mutant patients.

Study participants were aged 18 years and older with a confirmed diagnosis of ER-positive breast cancer and good performance status, as well as evidence of progression after endocrine therapy for metastatic disease or evidence of progression while on therapy or within 12 months from the end of adjuvant therapy.

“For all arms, prior fulvestrant, CDK46 inhibitor, or chemotherapy were allowed. For arm C, patients with or without PIK3C were eligible, and no prior treatment with PIK3, mTOR, or AKT inhibitors was allowed,” Dr. Jhaveri said.

Dosing in the LSZ102 monotherapy arm ranged from 200 to 900 mg. Arm B patients received LSZ102 at doses of 200-600 mg and ribociclib at doses of 200-600 mg. Both continuous ribociclib and 3 weeks on/1 week off dosing were evaluated. Arm C patients received LSZ102 at doses of 300-450 mg and alpelisib at 200-300 mg.

The recommended expansion doses were 450 mg daily of LSZ102 for arm A and 450 mg LSZ102 with 400 mg of daily ribociclib for arm B. For arm C, they were 300 mg LSZ102 with 250 mg of alpelisib daily.

Of note, two of three patients with a PR in arm C had received 300 mg LSZ102 and 300 mg alpelisib, Dr. Jhaveri said.

Arm A and arm B results were presented at the San Antonio Breast Cancer Symposium in 2018 and 2019, respectively. The current report updates those findings and presents arm C data for the first time, Dr. Jhaveri said.

LSZ102 was relatively well-tolerated as a single agent and in combination with ribociclib and alpelisib, according to Dr. Jhaveri. The most frequent adverse events were gastrointestinal toxicities, including nausea, vomiting, diarrhea, and decreased appetite, which occurred across all arms.

Neutropenia and aspartate aminotransferase abnormalities, including grade 3 cases, were reported in arm B and were most likely driven by the ribociclib, Dr. Jhaveri said. Grade 3 hypoglycemia and skin rash commonly occurred in arm C, most likely driven by the alpelisib.

Five dose-limiting toxicities occurred in four patients in arm A, three occurred in two patients in arm B, and seven occurred in seven patients in arm C.

Paired biopsies collected at the time of screening and at day 15 of cycle 1 showed consistent down-regulation of ER protein levels across arms.

“No substantial dose-dependent down-regulation of the ER was observed with increasing doses of LSZ,” Dr. Jhaveri said.

Circulating tumor DNA (ctDNA) analysis showed that the dominant mutations across the arms were ESR1, PIK3CA, and TP53. These were not shown to correlate with response and were not enriched upon progression in patients with matched baseline and end-of-treatment samples, she noted.

An exploratory analysis, conducted in “a preliminary attempt to correlate clinical activity with specific mutations,” showed that, in arms B and C, respectively, ORR, CBR, and PFS weren’t correlated with the presence or absence of ESR1 and PIK3CA mutations, respectively, or the absence of detectable ctDNA from baseline samples, Dr. Jhaveri said.

“While numerically higher responses and better CBR were seen in patients with undetectable ctDNA at baseline, no statistically significant difference in any of these outcomes was observed in arms B and C,” she said.

In arm C, the numbers were small at the time of data cutoff, but incoming data suggest relatively enhanced activity of the LSZ102 plus alpelisib combination in PIKC3A-mutant patients, she noted.

“We know that inhibiting ER signaling is the mainstay of treatment for ER-positive breast cancer,” Dr. Jhaveri explained, adding that aromatase inhibitors, estrogen receptor modulators, and SERDs are important classes of antiestrogenic agents, but fulvestrant is the only approved SERD. These are effective, but many patients develop resistance, she said.

“Proposed mechanisms for endocrine resistance include activation of the cell-cycle and cell-survival signaling pathways, or of the PI3K-AKT-mTOR pathway,” Dr. Jhaveri said. “To that end, ribociclib, a CDK46 inhibitor plus fulvestrant improved survival compared to fulvestrant alone in patients with ER-positive metastatic breast cancer.”

More recently, the PI3K inhibitor alpelisib plus fulvestrant also nearly doubled PFS vs. fulvestrant alone in PIKC3A-mutant, ER-positive metastatic breast cancer, which led to the approval of the combination in the United States.

Another mechanism of endocrine resistance includes acquisition of activating mutations in the estrogen receptor gene itself that allow tumors to survive and proliferate without depending on estrogen.

EGFR mutations appear to predict resistance to aromatase inhibitor therapies, but not outcomes in patients treated with fulvestrant. However, fulvestrant, which is delivered by intramuscular injection, has its own limitations, Dr. Jhaveri said.

“LSZ102 is a novel SERD that could achieve higher exposure than fulvestrant, leading to enhanced efficacy,” she said, noting that it was shown in preclinical models to have activity and to be synergistic in combination with ribociclib and alpelisib, forming the basis for the current study.

Invited discussant, Saverio Cinieri, MD, of Ospedale Antonio Perrino, Brindisi, Italy, said the study “elegantly demonstrated that estrogen receptor protein is down-regulated by LSZ102; [that] the genomic landscape of heavily pretreated patients is dominated by mutations in ESR1, PIK3CA, and TP53; [that] common mutations do not correlate with response and are not enriched on progression; [and that] ctDNA analysis at baseline shows similar outcomes with LSZ plus ribociclib or alpelisib, regardless of mutational status.”

LSZ102 is one of four new-generation SERDs in early-phase studies, he said, concluding that “in the COVID-19 era, the use of oral therapies will be even more necessary to limit access to the hospital.”

Dr. Cinieri also said that overcoming the limitations “of a molecule like the intramuscularly administered fulvestrant goes in this direction,” and that “the clinical efficacy and the biomolecular profile of LSZ102 seems to be able to meet these real needs.”

This study was funded by Novartis. Dr. Jhaveri reported advisory and consultancy roles and/or research grants or other funding to her institution from Novartis, ADC Therapeutics, Pfizer, and numerous other pharmaceutical and biotechnology companies. Dr. Cinieri reported relationships with Lily Oncology, Pfizer, Roche, AstraZeneca, Amgen, Novartis, including honoraria, grant and research support to his institution, advisory board participation, and scientific meeting support.

Planning for reduced use of opioids in pain management involves identifying appropriate patients and managing their expectations, according to according to Timothy E. Miller, MB, ChB, FRCA, of Duke University, Durham, N.C., who is president of the American Society for Enhanced Recovery.

Multimodal analgesia plans can be a beneficial part of enhanced recovery and may reduce or eliminate the need for opioids in some patients, he said in a presentation at the virtual Annual Minimally Invasive Surgery Symposium sponsored by Global Academy for Medical Education.

Dr. Miller shared a treatment algorithm for achieving optimal analgesia in patients after colorectal surgery that combines intravenous or oral analgesia with local anesthetics and additional nonopioid options. The algorithm involves choosing NSAIDs, acetaminophen, or gabapentin for IV/oral use. In addition, options for local anesthetic include with a choice of single-shot transversus abdominis plane (TAP) block.

Careful patient selection is key to an opioid-free or opioid reduced anesthetic strategy, Dr. Miller said. The appropriate patients have “no chronic opioids, no anxiety, and the desire to avoid opioid side effects,” he said.

Opioid-free or opioid-reduced strategies include realigning patient expectations to prepare for pain at a level of 2-4 on a scale of 10 as “expected and reasonable,” he said. Patients given no opioids or reduced opioids may report cramping after laparoscopic surgery, as well as shoulder pain that is referred from the CO₂ bubble under the diaphragm, he said. However, opioids don’t treat the shoulder pain well, and “walking or changing position usually relieves this pain,” and it usually resolves within 24 hours, Dr. Miller noted. “Just letting the patient know what is expected in terms of pain relief in their recovery is hugely important,” he said.

The optimal analgesia after surgery is a plan that combines optimized patient comfort with the fastest functional recovery and the fewest side effects, he emphasized.

Optimized patient comfort includes optimal pain ratings at rest and with movement, a decreasing impact of pain on emotion, function, and sleep disruption, and an improvement in the patient experience, he said. The fastest functional recovery is defined as a return to drinking liquids, eating solid foods, performing activities of daily living, and maintaining normal bladder, bowel, and cognitive function. Side effects to be considered in analgesia included nausea, vomiting, sedation, ileus, itching, dizziness, and delirium, he said.

In an unpublished study, Dr. Miller and colleagues eliminated opioids intraoperatively in a series of 56 cases of laparoscopic cholecystectomy and found significantly less opioids needed in the postanesthesia care unit (PACU). In addition, opioid-free patients had significantly shorter length of stay in the PACU, he said. “We are writing this up for publication and looking into doing larger studies,” Dr. Miller said.

Questions include whether the opioid-free technique translates more broadly, he said.

In addition, it is important to continue to collect data and study methods to treat pain and reduce opioid use perioperatively, Dr. Miller said. Some ongoing concerns include data surrounding the use of gabapentin and possible association with respiratory depression, he noted. Several meta-analyses have suggested that “gabapentinoids (gabapentin, pregabalin) when given as a single dose preoperatively are associated with a decrease in postoperative pain and opioid consumption at 24 hours,” said Dr. Miller. “When gabapentinoids are included in multimodal analgesic regimens, intraoperative opioids must be reduced, and increased vigilance for respiratory depression may be warranted, especially in elderly patients,” he said.

Overall, opioid-free anesthesia is both feasible and appropriate in certain patient populations, Dr. Miller concluded. “Implement your pathway and measure your outcomes with timely feedback so you can revise your protocol based on data,” he emphasized.

Dr. Miller disclosed relationships with Edwards Lifesciences, and serving as a board member for the Perioperative Quality Initiative and as a founding member of the Morpheus Consortium.

Planning for reduced use of opioids in pain management involves identifying appropriate patients and managing their expectations, according to according to Timothy E. Miller, MB, ChB, FRCA, of Duke University, Durham, N.C., who is president of the American Society for Enhanced Recovery.

Multimodal analgesia plans can be a beneficial part of enhanced recovery and may reduce or eliminate the need for opioids in some patients, he said in a presentation at the virtual Annual Minimally Invasive Surgery Symposium sponsored by Global Academy for Medical Education.

Dr. Miller shared a treatment algorithm for achieving optimal analgesia in patients after colorectal surgery that combines intravenous or oral analgesia with local anesthetics and additional nonopioid options. The algorithm involves choosing NSAIDs, acetaminophen, or gabapentin for IV/oral use. In addition, options for local anesthetic include with a choice of single-shot transversus abdominis plane (TAP) block.

Careful patient selection is key to an opioid-free or opioid reduced anesthetic strategy, Dr. Miller said. The appropriate patients have “no chronic opioids, no anxiety, and the desire to avoid opioid side effects,” he said.

Opioid-free or opioid-reduced strategies include realigning patient expectations to prepare for pain at a level of 2-4 on a scale of 10 as “expected and reasonable,” he said. Patients given no opioids or reduced opioids may report cramping after laparoscopic surgery, as well as shoulder pain that is referred from the CO₂ bubble under the diaphragm, he said. However, opioids don’t treat the shoulder pain well, and “walking or changing position usually relieves this pain,” and it usually resolves within 24 hours, Dr. Miller noted. “Just letting the patient know what is expected in terms of pain relief in their recovery is hugely important,” he said.

The optimal analgesia after surgery is a plan that combines optimized patient comfort with the fastest functional recovery and the fewest side effects, he emphasized.

Optimized patient comfort includes optimal pain ratings at rest and with movement, a decreasing impact of pain on emotion, function, and sleep disruption, and an improvement in the patient experience, he said. The fastest functional recovery is defined as a return to drinking liquids, eating solid foods, performing activities of daily living, and maintaining normal bladder, bowel, and cognitive function. Side effects to be considered in analgesia included nausea, vomiting, sedation, ileus, itching, dizziness, and delirium, he said.

In an unpublished study, Dr. Miller and colleagues eliminated opioids intraoperatively in a series of 56 cases of laparoscopic cholecystectomy and found significantly less opioids needed in the postanesthesia care unit (PACU). In addition, opioid-free patients had significantly shorter length of stay in the PACU, he said. “We are writing this up for publication and looking into doing larger studies,” Dr. Miller said.

The race to develop a SARS-CoV-2 vaccine is unlike any other global research and development effort in modern medicine.

According to Paul A. Offit, MD, there are now 120 Investigational New Drug applications to the Food and Drug Administration for these vaccines, and researchers at more than 70 companies across the globe are interested in making a vaccine. The Biomedical Advanced Research and Development Authority (BARDA) has awarded $2.5 billion to five different pharmaceutical companies to make a vaccine.

“The good news is that the new coronavirus is relatively stable,” Dr. Offit, director of the Vaccine Education Center at the Children’s Hospital of Philadelphia, said during the virtual Pediatric Dermatology 2020: Best Practices and Innovations Conference. “Although it is a single-stranded RNA virus, it does mutate to some extent, but it doesn’t look like it’s going to mutate away from the vaccine. So, this is not going to be like influenza virus, where you must give a vaccine every year. I think we can make a vaccine that will last for several years. And we know the protein we’re interested in. We’re interested in antibodies directed against the spike glycoprotein, which is abundantly present on the surface of the virus. We know that if we make an antibody response to that protein, we can therefore prevent infection.”

Some research groups are interested in developing a whole, killed virus like those used in the inactivated polio vaccine, and vaccines for hepatitis A virus and rabies, said Dr. Offit, who is a member of Accelerating COVID-19 Technical Innovations And Vaccines, a public-private partnership formed by the National Institutes of Health. Other groups are interested in making a live-attenuated vaccine like those for measles, mumps, and rubella. “Some are interested in using a vectored vaccine, where you take a virus that is relatively weak and doesn’t cause disease in people, like vesicular stomatitis virus, and then clone into that the gene that codes for this coronavirus spike protein, which is the way that we made the Ebola virus vaccine,” Dr. Offit said. “Those approaches have all been used before, with success.”

Novel approaches are also being employed to make this vaccine, including using a replication-defective adenovirus. “That means that the virus can’t reproduce itself, but it can make proteins,” he explained. “There are some proteins that are made, but most aren’t. Therefore, the virus can’t reproduce itself. We’ll see whether or not that [approach] works, but it’s never been used before.”

Another approach is to inject messenger RNA that codes for the coronavirus spike protein, where that genetic material is translated into the spike protein. The other platform being evaluated is a DNA vaccine, in which “you give DNA which is coded for that spike protein, which is transcribed to messenger RNA and then is translated to other proteins.”

Typical vaccine development involves animal models to prove the concept, dose-ranging studies in humans, and progressively larger safety and immunogenicity studies in hundreds of thousands of people. Next come phase 3 studies, “where the proof is in the pudding,” he said. “These are large, prospective placebo-controlled trials to prove that the vaccine is safe. This is the only way whether you can prove or not a vaccine is effective.”

According to Dr. Offit, the phase 3 COVID-19 vaccine trials supported by BARDA will launch in July 2020 and will enroll 20,000 people in the vaccine treatment arm and 10,000 in the placebo arm. “Some companies may branch out on their own and do smaller studies than that,” he said. “We’ll see how this plays out. Keep your eyes open for that, because you really want to make sure you have a fairly large phase 3 trial. That’s the best way to show whether something works and whether it’s safe.”

The tried and true vaccines that emerge from the effort will not be FDA-licensed products. Rather, they will be approved products under the Emergency Use Authorization program. “Ever since the 1950s, every vaccine that has been used in the U.S. has been under the auspices of FDA licensure,” said Dr. Offit, who is also professor of pediatrics and the Maurice R. Hilleman professor of vaccinology at the University of Pennsylvania, Philadelphia. “That’s not going to be true here. The FDA is involved every step of the way but here they have a somewhat lighter touch.”

A few candidate vaccines are being mass-produced at risk, “meaning they’re being produced not knowing whether these vaccines are safe and effective yet or not,” he said. “But when they’re shown in a phase 3 trial to be safe and effective, you will have already produced it, and then it’s much easier to roll it out to the general public the minute you’ve shown that it works. This is what we did for the polio vaccine back in the 1950s. We mass-produced that vaccine at risk.”

Dr. Offit emphasized the importance of managing expectations once a COVID-19 vaccine gets approved for use. “Regarding safety, these vaccines will be tested in tens of thousands of people, not tens of millions of people, so although you can disprove a relatively uncommon side effect preapproval, you’re not going to disprove a rare side effect preapproval. You’re only going to know that post approval. I think we need to make people aware of that and to let them know that through groups like the Vaccine Safety Datalink, we’re going to be monitoring these vaccines once they’re approved.”

Regarding efficacy, he continued, “we’re not going know about the rates of immunity initially; we’re only going to know about that after the vaccine [has been administered]. My guess is the protection is going to be short lived and incomplete. By short lived, I mean that protection would last for years but not decades. By incomplete, I mean that protection will be against moderate to severe disease, which is fine. You don’t need protection against all of the disease; it’s hard to do that with respiratory viruses. That means you can keep people out of the hospital, and you can keep them from dying. That’s the main goal.”

Dr. Offit closed his remarks by noting that much is at stake in this effort to develop a vaccine so quickly and that it “could go one of two ways. We could find that the vaccine is a lifesaver, and [that] we can finally end this awful pandemic. Or, if we cut corners and don’t prove that the vaccines are safe and effective as we should before they’re released, we could shake what is a fragile vaccine confidence in this country. Hopefully, it doesn’t play out that way.”

Although about two of five physicians report a net worth of between $1 million and $5 million, half are under the million dollars and about half believe in living at or below their means, according to the latest Medscape Physician Debt and Net Worth Report 2020.

43% live below their means

Asked about habits regarding saving, 43% of physicians reported they live below their means. Half said they live at their means, and 7% said they live above their means.

Joel Greenwald, MD, CEO of Greenwald Wealth Management in St. Louis Park, Minn., recommends in the report trying to save 20% of annual gross salary.

More than a third of physicians who responded (39%) said they put more than $2,000/month into tax-deferred retirement or college savings, but Dr. Greenwald acknowledged that this may become more challenging.

“Many have seen the employer match in their retirement plans reduced or eliminated through the end of 2020, with what comes in 2021 as yet undefined,” he said.

A smaller percentage (26%) answered that they put more than $2,000 a month into a taxable retirement or college savings account each month.

Home size by specialty

Mortgages on a primary residence were the top reasons for debt (63%), followed by car loans (37%), personal education loans (26%), and credit card balances (25%).

Half of specialists and 61% of primary care physicians live in homes with up to 3,000 square feet. Only 7% of PCPs and 12% of specialists live in homes with 5000 square feet or more.

At 22%, plastic surgeons and orthopedists were the most likely groups to have houses with the largest square footage, according to the survey.

About one in four physicians in five specialties (urology, cardiology, plastic surgery, otolaryngology, and critical care) reported that they had mortgages of more than $500,000.

Standard financial advice, the report authors note, is that a mortgage should take up no more than 28% of monthly gross income.

Another large source of debt came from student loans. Close to 80% of graduating medical students have educational debt. The average balance for graduating students in 2018 was $196,520, the report authors state.

Those in physical medicine/rehabilitation and family medicine were most likely to still be paying off student debt (34% said they were). Conversely, half as many nephrologists and rheumatologists (15%) and gastroenterologists (14%) reported that they were paying off educational debt.

Only 11% of physicians said they were currently free of any debt.

Most physicians in the survey (72%) reported that they had not experienced a significant financial loss in the past year.

For those who did experience such a loss, the top reason given was related to a bad investment or the stock market (9%).
 

Cost-cutting strategies

Revenue reduction will likely lead to spending less this year as the pandemic challenges continue.

Survey respondents offered their most effective cost-cutting strategies.

A hospitalist said, “Half of every bonus goes into the investment account, no matter how much.”

“We add an extra amount to the principal of our monthly mortgage payment,” an internist said.

A pediatrician offered, “I bring my lunch to work every day and don’t eat in restaurants often.”

Although about two of five physicians report a net worth of between $1 million and $5 million, half are under the million dollars and about half believe in living at or below their means, according to the latest Medscape Physician Debt and Net Worth Report 2020.

43% live below their means

Asked about habits regarding saving, 43% of physicians reported they live below their means. Half said they live at their means, and 7% said they live above their means.

Joel Greenwald, MD, CEO of Greenwald Wealth Management in St. Louis Park, Minn., recommends in the report trying to save 20% of annual gross salary.

More than a third of physicians who responded (39%) said they put more than $2,000/month into tax-deferred retirement or college savings, but Dr. Greenwald acknowledged that this may become more challenging.

“Many have seen the employer match in their retirement plans reduced or eliminated through the end of 2020, with what comes in 2021 as yet undefined,” he said.

A smaller percentage (26%) answered that they put more than $2,000 a month into a taxable retirement or college savings account each month.

Home size by specialty

Mortgages on a primary residence were the top reasons for debt (63%), followed by car loans (37%), personal education loans (26%), and credit card balances (25%).

Half of specialists and 61% of primary care physicians live in homes with up to 3,000 square feet. Only 7% of PCPs and 12% of specialists live in homes with 5000 square feet or more.

At 22%, plastic surgeons and orthopedists were the most likely groups to have houses with the largest square footage, according to the survey.

About one in four physicians in five specialties (urology, cardiology, plastic surgery, otolaryngology, and critical care) reported that they had mortgages of more than $500,000.

Standard financial advice, the report authors note, is that a mortgage should take up no more than 28% of monthly gross income.

Another large source of debt came from student loans. Close to 80% of graduating medical students have educational debt. The average balance for graduating students in 2018 was $196,520, the report authors state.

Those in physical medicine/rehabilitation and family medicine were most likely to still be paying off student debt (34% said they were). Conversely, half as many nephrologists and rheumatologists (15%) and gastroenterologists (14%) reported that they were paying off educational debt.

Only 11% of physicians said they were currently free of any debt.

Most physicians in the survey (72%) reported that they had not experienced a significant financial loss in the past year.

For those who did experience such a loss, the top reason given was related to a bad investment or the stock market (9%).
 

Cost-cutting strategies

Revenue reduction will likely lead to spending less this year as the pandemic challenges continue.

Survey respondents offered their most effective cost-cutting strategies.

A hospitalist said, “Half of every bonus goes into the investment account, no matter how much.”

“We add an extra amount to the principal of our monthly mortgage payment,” an internist said.

A pediatrician offered, “I bring my lunch to work every day and don’t eat in restaurants often.”

The Food and Drug Administration approved a combination of pertuzumab (Perjeta, Genentech/Roche), trastuzumab (Herceptin, Genentech/Roche) and hyaluronidase (Phesgo, Genentech/Roche) that is administered subcutaneously – rather than intravenously – for the treatment of early and metastatic HER2-positive breast cancers.

Phesgo is initially used in combination with chemotherapy at an infusion center but could continue to be administered in a patient’s home by a qualified health care professional once chemotherapy is complete, according to the FDA.

Administration takes approximately 8 minutes for the initial loading dose and approximately 5 minutes for maintenance doses, according to a Genentech press statement. This compares favorably with the 150 minutes needed for the combined loading dose of intravenous pertuzumab and trastuzumab, and the 60-150 minutes for intravenous maintenance infusions, the company said.

“Currently, most patients with HER2-positive breast cancer receive trastuzumab and pertuzumab at infusion centers. With a new administration route, Phesgo offers an outpatient option for patients to receive trastuzumab and pertuzumab,” said Richard Pazdur, MD, director of the FDA’s Oncology Center of Excellence and acting director of the Office of Oncologic Diseases in the FDA’s Center for Drug Evaluation and Research, in an agency press release.

“The fixed-dose combination of trastuzumab and pertuzumab offers a simpler, faster, and easier treatment experience for patients with HER2-positive breast cancer,” said Antoinette Tan, MD, MHSc, chief of breast medical oncology at Levine Cancer Institute, Charlotte, N.C., in the company statement.

Dr. Tan also said that home administration “can be advantageous for patients and infusion centers.”

However, in April, the Community Oncology Alliance strenuously objected to this type of treatment in a patient’s home, as reported by Medscape Medical News.

The group, which represents U.S. community-based practices, said it “fundamentally opposes home infusion of chemotherapy, cancer immunotherapy, and cancer treatment supportive drugs because of serious patient safety concerns.”

The FDA’s approval was based on the results of the pivotal phase 3 FeDeriCa trial, a noninferiority study in patients with HER2-positive early breast cancer, which demonstrated that the new product had comparable efficacy and safety as intravenous pertuzumab and intravenous trastuzumab.

In terms of efficacy, the subcutaneous product demonstrated noninferior plasma levels of pertuzumab, which was the primary endpoint, when compared with IV administration of pertuzumab.

Safety was comparable between the two approaches, with no new safety signals using the subcutaneous delivery method, including no “meaningful difference” in cardiac toxicity, according to Genentech. However, there were more administration-related reactions with the new product. The most common adverse events in both groups were alopecia, nausea, diarrhea, and anemia.

The new product uses a drug delivery technology (Enhanze, Halozyme Therapeutics) that employs a proprietary enzyme that temporarily degrades hyaluronan, a glycosaminoglycan or chain of natural sugars in the body, to facilitate the dispersion and absorption of injected therapeutic drugs, according to Genentech.

In May, at the European Society for Medical Oncology Breast Cancer Virtual Meeting 2020, investigators of the phase 2 PHranceSCa study reported that “more than 80%” of patients preferred subcutaneous to intravenous administration of pertuzumab and trastuzumab.

There are at least five dermatologic patterns in patients who are suspected or confirmed of having COVID-19, and the knowledge base continues to evolve, according to Christine Ko, MD.

“Things are very fluid,” Dr. Ko, professor of dermatology and pathology at Yale University, New Haven, Conn., said during the virtual annual meeting of the American Academy of Dermatology. “New studies are coming out daily. Due to the need for rapid dissemination, a lot of the studies are case reports, but there are some nice case series. Another caveat for the literature is that a lot of these cases were not necessarily confirmed with testing for SARS-CoV-2, but some were.”

Dr. Ko framed her remarks largely on a case collection survey of images and clinical data from 375 patients in Spain with suspected or confirmed COVID-19 that was published online April 29, 2020, in the British Journal of Dermatology (doi: 10.1111/bjd.19163). Cutaneous manifestations included early vesicular eruptions mainly on the trunk or limbs (9%), maculopapular (47%) to urticarial lesions (19%) mainly on the trunk, and acral areas of erythema sometimes with vesicles or erosion (perniosis-like) (19%) that seemed to be a later manifestation of COVID-19. Retiform purpura or necrosis (6%) was most concerning in terms of skin disease, with an associated with a mortality of 10%.

On histology, the early vesicular eruptions are typically marked by dyskeratotic keratinocytes, Dr. Ko said, while urticarial lesions are characterized by a mixed dermal infiltrate; maculopapular lesions were a broad category. “There are some case reports that show spongiotic dermatitis or parakeratosis with a lymphocytic infiltrate,” she said. “A caveat to keep in mind is that, although these patients may definitely have COVID-19 and be confirmed to have it by testing, hypersensitivity reactions may be due to the multiple medications they’re on.”

Patients can develop a spectrum of lesions that are suggestive of vascular damage or occlusion, Dr. Ko continued. Livedoid lesions may remain static and not eventuate into necrosis or purpura but will self-resolve. Purpuric lesions and acral gangrene have been described, and these lesions correspond to vascular occlusion on biopsy.

A later manifestation are the so-called “COVID toes” with a superficial and deep lymphocytic infiltrate, as published June 1, 2020, in JAAD Case Reports: (doi: 10.1016/j.jdcr.2020.04.011).

“There are patients in the literature that have slightly different pathology, with lymphocytic inflammation as well as occlusion of vessels,” Dr. Ko said. A paper published June 20, 2020, in the British Journal of Dermatology used immunohistochemical staining against the SARS-CoV-2 spike protein, and biopsies of “COVID toes” had positive staining of endothelial cells, supporting the notion that “COVID toes” are a direct manifestation of viral infection (doi: 10.1111/bjd.19327).

“There’s a lot that we still don’t know, and some patterns are going to be outliers,” Dr. Ko concluded. “[As for] determining which skin manifestations are directly from coronavirus infection within the skin, more study is needed and likely time will tell.” She reported having no financial disclosures relevant to her talk.
