FDA approves new ready-to-inject glucagon product
The Food and Drug Administration has approved dasiglucagon (Zegalogue 0.6 mg/0.6 mL, Zealand Pharma) autoinjector and prefilled syringe for the treatment of severe hypoglycemia in people with diabetes aged 6 years and older.
The product has a shelf-life of 36 months at refrigerated temperatures and is stable for up to 12 months at room temperature.
“This approval will help enable appropriate children and adults with diabetes to be able to address sudden and severe hypoglycemia, which can quickly progress from a mild event to an emergency,” Jeremy Pettus, MD, assistant professor of medicine at the University of California, San Diego, said in a company statement.
The approval marks the latest step in the development of newer glucagon formulations that are easier to use in hypoglycemic emergencies than the traditional formulation that requires several steps for reconstitution.
The first intranasal glucagon (Baqsimi, Eli Lilly) was approved in the United States in July 2019 for people with diabetes age 4 years and older.
In September 2019, the FDA approved another prefilled glucagon rescue pen (Gvoke HypoPen, Xeris Pharmaceuticals) for the treatment of severe hypoglycemia in adult and pediatric patients age 2 years and older with diabetes.
Dasiglucagon is currently in phase 3 trials as a subcutaneous infusion for treating congenital hyperinsulinemia, and in phase 2 trials as part of a bihormonal artificial pancreas pump system.
The FDA approval was based on results from three randomized, double-blind, placebo-controlled, phase 3 studies of dasiglucagon in children age 6-17 years and adults with type 1 diabetes.
The primary endpoint was time to achieving an increase in blood glucose of 20 mg/dL or greater from time of administration without additional intervention within 45 minutes. That endpoint was achieved in all three studies, with a median time to blood glucose recovery of 10 minutes overall, with 99% of adults recovering within 15 minutes.
The most common adverse events reported in 2% or more of study participants were nausea, vomiting, headache, and injection-site pain in both children and adults. Diarrhea was also reported in adults.
Full launch is expected in late June 2021.

Servier and French drug safety agency found guilty on diet drug
More than 10 years after the withdrawal of the weight-loss drug Mediator (benfluorex) from the market in France, the Paris Court issued its judgment on March 29, 2021, against Servier Laboratories and the French National Agency for the Safety of Medicines and Health Products (ANSM).
Servier Laboratories was convicted of “aggravated deception” and fined 2.7 million euros (approximately $3.2 million) but were found not guilty of fraud. ANSM will also have to pay a fine.
Mediator was brought to the market in 1976 for the treatment of hyperlipidemia and for overweight patients with type 2 diabetes but was used off label as an appetite suppressant. It was taken by 5 million people and was only removed from the market in France in 2009 because of its toxic effects.
Mediator was taken off the market in Spain 6 years earlier, and in Switzerland 12 years earlier, and more than 30 years before in Belgium. It was never marketed in the United States.
The number of deaths because of heart valve damage related to the drug in France has been estimated at 220-300 in the short term (2.5 years) and 1,300-1,800 in the long term. In addition, the drug has been responsible for 3,100-4,200 hospital admissions for valvular insufficiency and pulmonary arterial hypertension.
“Despite knowing the risks for very many years ... [Servier Laboratories] never took the necessary measures and thus deceived” consumers of Mediator, declared the president of the criminal court, Sylvie Daunois.
Servier has “weakened confidence in the health system,” she added.
“I am very happy that ‘aggravated deception,’ the heart of the case, has been recognized and condemned,” Irène Frachon, MD, a pulmonologist at Brest (France) University Hospital and whistleblower on the Mediator scandal, said in an interview.
However, Dr. Frachon continued: “The major problem, putting a toxic agent on the market for years, is a given. But the weakness of the sentences gives a mixed message.
“The judgment is too cautious in its punishments,” she added, pointing out that, “in the case of contaminated blood, there were prison sentences.”
Servier deceived doctors and patients
The French trial in September 2019 was extraordinary, with about 100 witnesses, nearly 400 lawyers, and 5,000 victims.
On June 23, 2020, the prosecutor, Aude Le Guilcher, requested at the end of her indictment that the six companies of the Servier group be fined, notably for “deception, homicide, involuntary injuries, and fraud,” to the tune of 20.3 million euros (approximately $23.8 million).
Against the former No. 2 of Servier, Jean-Philippe Seta, Ms. Le Guilcher requested 5 years in prison, with 2 years suspended, and a 200,000 euro (approximately $235,000) fine.
The same sum was requested against ANSM for homicide and unintentional injuries.
In the end, Mr. Seta, the former right hand of Jacques Servier, who died in 2004, was sentenced to 4 years in prison, suspended. For their part, ANSM was fined 303,000 euros(approximately $350,000).
It is now clearly established that Servier Laboratories knowingly concealed the similarity of Mediator to the fenfluramine family of compounds, which was banned in 1990 because of adverse effects.
The group also deceived doctors who prescribed the drug and patients who took it by hiding its toxicity.
Mediator should never have been authorized for use
In terms of the fraud charges, the prosecutor estimated that the losses incurred by the primary health insurance industry were in the region of several hundred million euros.
She argued that Mediator should never have been reimbursed, as “it should never have benefited from market authorization, which it received solely due to the fraudulent actions of the company.”
But because of the statute of limitations, this argument was not heard, explained Dr. Frachon, “and the same is true of conflicts of interest, where limitations led to them being discharged.
“We understand the legal difficulties, but it’s a shame in terms of the signal sent.”
“I hope the medical world will learn the lesson and not continue with ‘business as usual’ with people who are delinquents. I think it will be essential to restore public confidence,” concluded Dr. Frachon.
No conflicts of interest or funding were declared.

Steroids can be stopped in some older multiple myeloma patients
For select older patients, it is safe to switch to a lower dose of lenalidomide maintenance therapy and discontinue dexamethasone after 9 months. The regimen is safe and yields outcomes similar to those of standard, continuous lenalidomide/dexamethasone (Rd), according to new findings.
At a median follow-up of 37 months, event-free survival was 10.4 months in the experimental arm in which dexamethasone therapy was stopped (Rd-R) versus 6.9 months for standard therapy. The tailored approach also resulted in fewer adverse effects.
The authors noted that there was no difference in progression-free survival (PFS) and overall survival between the two groups.
“These results may be useful for the treatment of myeloma patients, since approximately one-third of patients not eligible for stem cell transplantation are intermediate fit, the population in our study,” said lead author Alessandra Larocca, MD, PhD, from the department of hematology-oncology of the University Hospital Città della Salute e della Scienza, Torino, Italy.
She said in an interview that they expect that these findings “may help to optimize the treatment of less-fit elderly patients by reducing the occurrence of adverse events and thus improving outcomes and preserving quality of life of these patients.”
This approach is a viable option for clinicians to consider for some patient subgroups. “This steroid-sparing approach can also be used in other combinations,” she said. “Ongoing trials are now evaluating steroid sparing in combination with monoclonal antibodies or the role of frailty-guided treatment.”
The study was published March 19, 2021, in Blood.
Curtailing steroids
Myeloma patients aged 75 years or older or who have comorbidities and functional impairments are an understudied population. They are more susceptible to adverse events that may negatively affect the duration of treatment and outcomes. Steroids are “scarcely tolerated” in the long term, even among younger patients, and “whether sparing dexamethasone is as effective as prolonged steroid exposure remains an open issue,” the authors wrote. There are still no clear data on the advantage of continuous steroid treatment as opposed to fixed-duration treatment for newly diagnosed patients.
In 2010, a study compared high-dose with low-dose dexamethasone. As expected, the rate of adverse events was lower among patients who received the low-dose steroid, but quite unexpectedly, deaths with high-dose dexamethasone were significantly higher than with low-dose dexamethasone.
The 1-year overall survival was 96% among patients who received the low dose of dexamethasone versus 87% with the standard high dose.
S. Vincent Rajkumar, MD, of the Mayo Clinic, Rochester, Minn., who was the lead author of the 2010 study, spoke with this new organization about the current study. “This is an important and practice-changing study,” he said. “We have already changed our practice and recommendations based on this study.”
He explained that, for transplant-ineligible patients, instead of initial therapy with bortezomib-lenalidomide-dexamethasone followed by Rd, they use lenalidomide alone without steroids.
“After 9 months of initial therapy, I now recommend we stop dexamethasone unless we are having problems controlling the myeloma, such as progressive disease,” Dr. Rajkumar said. “I congratulate the authors on a study that will improve the quality of life for our patients.”
Improved event-free survival
In this study, Dr. Larocca and colleagues investigated the efficacy and feasibility of a dose- and schedule-adjusted Rd regimen that was followed by maintenance Rd-R 10 mg/d and compared the regimen with continuous Rd in elderly, intermediate-fit patients who were newly diagnosed with multiple myeloma.
The primary endpoint was event-free survival, defined as progression/death from any cause, lenalidomide discontinuation, and any hematologic grade 4 or nonhematologic grade 3-4 adverse events.
The cohort consisted of 199 patients who were randomly assigned to receive either Rd-R (n = 101) or continuous Rd (n = 98). The median age was 75 years in the Rd-R arm and 76 years in the Rd arm; 52% of patients in the Rd-R group and 43% in the Rd group were classified as being intermediate fit not for age but for geriatric impairments.
With a median follow-up of 37 months, event-free survival was 10.4 months in the Rd-R arm versus 6.9 months in the Rd arm (hazard ratio, 0.70; P = .02). This benefit was maintained beyond nine cycles (median: 19.8 vs. 10.6 months for Rd-R vs. Rd; HR, 0.55; P = .03)
The median PFS was 20.2 months with Rd-R and 18.3 months with Rd (HR, 0.78; P = .16). The median overall survival was not reached. The 3-year overall survival was 74% with Rd-R and 63% with continuous Rd (HR, 0.62; P = .06). Among patients remaining on therapy after nine cycles, no difference in median PFS was observed between the two groups (24.3 vs. 18.7 months; HR, 0.73; P = .19).
Best response was similar for both groups, with an overall response rate of 78% versus 68% (P = .15). The very good partial response rate was 51% in the Rd-R arm versus 39% in the continuous Rd arm (P = .09).
Toxicities were similar between the two groups. Hematologic adverse events of at least grade 3 were reported in 26% of Rd-R patients versus 20% of Rd patients (P = .40). In both groups, the most frequent grade ≥3 hematologic toxicity was neutropenia (21% vs 18%). The most frequent grade ≥3 toxicities were nonhematologic. They occurred in 33% of Rd-R patients and 43% of Rd patients (P = .15). The most frequent nonhematologic toxicities were infections (10% vs. 12%), constitutional (3% vs. 12%), dermatologic (7% vs. 3%), and central nervous toxicities (2% vs. 6%).
The study was sponsored by Fondazione EMN Italy Onlus. Dr. Larocca has received honoraria from Amgen, Bristol-Myers Squibb, Celgene, Janssen, and GlaxoSmithKline, and has served on the advisory boards for Bristol-Myers Squibb, Celgene, Janssen, and Takeda. Several coauthors also have disclosed relationships with industry. Dr. Rajkumar disclosed no relevant financial relationships.

Myeloma patients aged 75 years or older or who have comorbidities and functional impairments are an understudied population. They are more susceptible to adverse events that may negatively affect the duration of treatment and outcomes. Steroids are “scarcely tolerated” in the long term, even among younger patients, and “whether sparing dexamethasone is as effective as prolonged steroid exposure remains an open issue,” the authors wrote. There are still no clear data on the advantage of continuous steroid treatment as opposed to fixed-duration treatment for newly diagnosed patients.
In 2010, a study compared high-dose with low-dose dexamethasone. As expected, the rate of adverse events was lower among patients who received the low-dose steroid, but quite unexpectedly, deaths with high-dose dexamethasone were significantly higher than with low-dose dexamethasone.
The 1-year overall survival was 96% among patients who received the low dose of dexamethasone versus 87% with the standard high dose.
S. Vincent Rajkumar, MD, of the Mayo Clinic, Rochester, Minn., who was the lead author of the 2010 study, spoke with this new organization about the current study. “This is an important and practice-changing study,” he said. “We have already changed our practice and recommendations based on this study.”
He explained that, for transplant-ineligible patients, instead of initial therapy with bortezomib-lenalidomide-dexamethasone followed by Rd, they use lenalidomide alone without steroids.
“After 9 months of initial therapy, I now recommend we stop dexamethasone unless we are having problems controlling the myeloma, such as progressive disease,” Dr. Rajkumar said. “I congratulate the authors on a study that will improve the quality of life for our patients.”
Improved event-free survival
In this study, Dr. Larocca and colleagues investigated the efficacy and feasibility of a dose- and schedule-adjusted Rd regimen that was followed by maintenance Rd-R 10 mg/d and compared the regimen with continuous Rd in elderly, intermediate-fit patients who were newly diagnosed with multiple myeloma.
The primary endpoint was event-free survival, defined as progression/death from any cause, lenalidomide discontinuation, and any hematologic grade 4 or nonhematologic grade 3-4 adverse events.
The cohort consisted of 199 patients who were randomly assigned to receive either Rd-R (n = 101) or continuous Rd (n = 98). The median age was 75 years in the Rd-R arm and 76 years in the Rd arm; 52% of patients in the Rd-R group and 43% in the Rd group were classified as being intermediate fit not for age but for geriatric impairments.
With a median follow-up of 37 months, event-free survival was 10.4 months in the Rd-R arm versus 6.9 months in the Rd arm (hazard ratio, 0.70; P = .02). This benefit was maintained beyond nine cycles (median: 19.8 vs. 10.6 months for Rd-R vs. Rd; HR, 0.55; P = .03)
The median PFS was 20.2 months with Rd-R and 18.3 months with Rd (HR, 0.78; P = .16). The median overall survival was not reached. The 3-year overall survival was 74% with Rd-R and 63% with continuous Rd (HR, 0.62; P = .06). Among patients remaining on therapy after nine cycles, no difference in median PFS was observed between the two groups (24.3 vs. 18.7 months; HR, 0.73; P = .19).
Best response was similar for both groups, with an overall response rate of 78% versus 68% (P = .15). The very good partial response rate was 51% in the Rd-R arm versus 39% in the continuous Rd arm (P = .09).
Toxicities were similar between the two groups. Hematologic adverse events of at least grade 3 were reported in 26% of Rd-R patients versus 20% of Rd patients (P = .40). In both groups, the most frequent grade ≥3 hematologic toxicity was neutropenia (21% vs 18%). The most frequent grade ≥3 toxicities were nonhematologic. They occurred in 33% of Rd-R patients and 43% of Rd patients (P = .15). The most frequent nonhematologic toxicities were infections (10% vs. 12%), constitutional (3% vs. 12%), dermatologic (7% vs. 3%), and central nervous toxicities (2% vs. 6%).
The study was sponsored by Fondazione EMN Italy Onlus. Dr. Larocca has received honoraria from Amgen, Bristol-Myers Squibb, Celgene, Janssen, and GlaxoSmithKline, and has served on the advisory boards for Bristol-Myers Squibb, Celgene, Janssen, and Takeda.

National Psoriasis Foundation recommends some stop methotrexate for 2 weeks after J&J vaccine
The , Joel M. Gelfand, MD, said at Innovations in Dermatology: Virtual Spring Conference 2021.
The new guidance states: “Patients 60 or older who have at least one comorbidity associated with an increased risk for poor COVID-19 outcomes, and who are taking methotrexate with well-controlled psoriatic disease, may, in consultation with their prescriber, consider holding it for 2 weeks after receiving the Ad26.COV2.S [Johnson & Johnson] vaccine in order to potentially improve vaccine response.”
The key word here is “potentially.” There is no hard evidence that a 2-week hold on methotrexate after receiving the killed adenovirus vaccine will actually provide a clinically meaningful benefit. But it’s a hypothetical possibility. The rationale stems from a small randomized trial conducted in South Korea several years ago in which patients with rheumatoid arthritis were assigned to hold or continue their methotrexate for the first 2 weeks after receiving an inactivated-virus influenza vaccine. The antibody response to the vaccine was better in those who temporarily halted their methotrexate, explained Dr. Gelfand, cochair of the NPF COVID-19 Task Force and professor of dermatology and of epidemiology at the University of Pennsylvania, Philadelphia.
“If you have a patient on methotrexate who’s 60 or older and whose psoriasis is completely controlled and quiescent and the patient is concerned about how well the vaccine is going to work, this is a reasonable thing to consider in someone who’s at higher risk for poor outcomes if they get infected,” he said.
If the informed patient wants to continue on methotrexate without interruption, that’s fine, too, in light of the lack of compelling evidence on this issue, the dermatologist added at the conference, sponsored by MedscapeLIVE! and the producers of the Hawaii Dermatology Seminar and Caribbean Dermatology Symposium.
The NPF task force does not extend the recommendation to consider holding methotrexate in recipients of the mRNA-based Moderna and Pfizer vaccines because of their very different mechanisms of action. Nor is it recommended to hold biologic agents after receiving any of the available COVID-19 vaccines. Studies have shown no altered immunologic response to influenza or pneumococcal vaccines in patients who continued on tumor necrosis factor inhibitors or interleukin-17 inhibitors. The interleukin-23 inhibitors haven’t been studied in this regard.
The task force recommends that most psoriasis patients should continue on treatment throughout the pandemic, and newly diagnosed patients should commence appropriate therapy as if there was no pandemic.
“We’ve learned that many patients who stopped their treatment for psoriatic disease early in the pandemic came to regret that decision because their psoriasis flared and got worse and required reinstitution of therapy,” Dr. Gelfand said. “The current data is largely reassuring that if there is an effect of our therapies on the risk of COVID, it must be rather small and therefore unlikely to be clinically meaningful for our patients.”
Dr. Gelfand reported serving as a consultant to and recipient of institutional research grants from Pfizer and numerous other pharmaceutical companies.

First CAR T-cell therapy for multiple myeloma: Abecma
Chimeric antigen receptor (CAR) T-cell therapy, described as a “living drug,” is now available for patients with relapsed/refractory multiple myeloma who have been treated with four or more prior lines of therapy.
The Food and Drug Administration said these patients represent an “unmet medical need” when it granted approval for the new product – idecabtagene vicleucel (ide-cel; Abecma), developed by bluebird bio and Bristol-Myers Squibb.
Ide-cel is the first CAR T-cell therapy to gain approval for use in multiple myeloma. It is also the first CAR T-cell therapy to target B-cell maturation antigen.
Previously approved CAR T-cell products target CD19 and have been approved for use in certain types of leukemia and lymphoma.
All the CAR T-cell therapies are customized treatments that are created specifically for each individual patient from their own blood. The patient’s own T cells are removed from the blood, are genetically modified and expanded, and are then infused back into the patient. These modified T cells then seek out and destroy blood cancer cells, and they continue to do so long term.
In some patients, this has led to eradication of disease that had previously progressed with every other treatment that had been tried – results that have been described as “absolutely remarkable” and “one-shot therapy that looks to be curative.”
However, this cell therapy comes with serious adverse effects, including neurologic toxicity and cytokine release syndrome (CRS), which can be life threatening. For this reason, all these products have a risk evaluation and mitigation strategy, and the use of CAR T-cell therapies is limited to designated centers.
In addition, these CAR T-cells products are phenomenally expensive; hospitals have reported heavy financial losses with their use, and patients have turned to crowdfunding to pay for these therapies.
‘Phenomenal’ results in MM
The FDA noted that approval of ide-cel for multiple myeloma is based on data from a multicenter study that involved 127 patients with relapsed/refractory disease who had received at least three prior lines of treatment.
The results from this trial were published Feb. 25 in the New England Journal of Medicine.
An expert not involved in the trial described the results as “phenomenal.”
Krina Patel, MD, an associate professor in the department of lymphoma/myeloma at the University of Texas MD Anderson Cancer Center, Houston, said that “the response rate of 73% in a patient population with a median of six lines of therapy, and with one-third of those patients achieving a deep response of complete response or better, is phenomenal.
“We are very excited as a myeloma community for this study of idecabtagene vicleucel for relapsed/refractory patients,” Dr. Patel told this news organization at the time.
The lead investigator of the study, Nikhil Munshi, MD, of Dana-Farber Cancer Institute, Boston, commented:
Both experts highlighted the poor prognosis for patients with relapsed/refractory disease. Recent decades have seen a flurry of new agents for myeloma, and there are now three main classes of agents: immunomodulatory agents, proteasome inhibitors, and anti-CD38 antibodies.
Nevertheless, in some patients, the disease continues to progress. For patients for whom treatments with all three classes of drugs have failed, the median progression-free survival is 3-4 months, and the median overall survival is 9 months.
In contrast, the results reported in the NEJM article showed that overall median progression-free survival was 8.8 months, but it was more than double that (20.2 months) for patients who achieved a complete or stringent complete response.
Estimated median overall survival was 19.4 months, and the overall survival was 78% at 12 months. The authors note that overall survival data are not yet mature.
The patients who were enrolled in the CAR T-cell trial had undergone many previous treatments. They had undergone a median of six prior drug therapies (range, 3-16), and most of the patients (120, 94%) had also undergone autologous hematopoietic stem cell transplant.
In addition, the majority of patients (84%) had disease that was triple refractory (to an immunomodulatory agent, a proteasome inhibitor, and an anti-CD38 antibody), 60% had disease that was penta-exposed (to bortezomib, carfilzomib, lenalidomide, pomalidomide, and daratumumab), and 26% had disease that was penta-refractory.
In the NEJM article, the authors report that about a third of patients had a complete response to CAR T-cell therapy.
At a median follow-up of 13.3 months, 94 of 128 patients (73%) showed a response to therapy (P < .001); 42 (33%) showed a complete or stringent complete response; and 67 patients (52%) showed a “very good partial response or better,” they write.
In the FDA announcement of the product approval, the figures for complete response were slightly lower. “Of those studied, 28% of patients showed complete response – or disappearance of all signs of multiple myeloma – to Abecma, and 65% of this group remained in complete response to the treatment for at least 12 months,” the agency noted.
The FDA also noted that treatment with Abecma can cause severe side effects. The label carries a boxed warning regarding CRS, hemophagocytic lymphohistiocytosis/macrophage activation syndrome, neurologic toxicity, and prolonged cytopenia, all of which can be fatal or life threatening.
The most common side effects of Abecma are CRS, infections, fatigue, musculoskeletal pain, and a weakened immune system. Side effects from treatment usually appear within the first 1-2 weeks after treatment, but some side effects may occur later.
The agency also noted that, to further evaluate the long-term safety of the drug, it is requiring the manufacturer to conduct a postmarketing observational study.
“The FDA remains committed to advancing novel treatment options for areas of unmet patient need,” said Peter Marks, MD, PhD, director of the FDA’s Center for Biologics Evaluation and Research.
“While there is no cure for multiple myeloma, the long-term outlook can vary based on the individual’s age and the stage of the condition at the time of diagnosis. Today’s approval provides a new treatment option for patients who have this uncommon type of cancer.”

Denosumab now dominant therapy for osteoporosis linked to cancer
Amid a substantial expansion of therapies in several drug classes for the treatment of osteoporosis, there has been a notable increase in the prescription of denosumab for patients with a cancer-related indication.
In an analysis of claims data from January 2009 to March 2020, the bisphosphonate alendronate represented more than 50% of all prescriptions for bone-directed therapies, but growth in the use of the monoclonal antibody denosumab overall and in cancer-related indications particularly was steady throughout the study period.
“In the malignancy cohort, alendronate and zoledronic acid were each used in approximately 30% of individuals at the onset of the study, but use of both then declined,” Sara Cromer, MD, reported at the annual meeting of the Endocrine Society.
For malignancy-based prescriptions, denosumab surpassed either bisphosphonate by 2013 and then continued to rise.
Denosumab use “reached approximately 50% of all bone-directed medication use in the malignancy cohort” by the end of the study period, said Dr. Cromer, a clinical research fellow in endocrinology at Massachusetts General Hospital, Boston.
The claims data for this analysis was drawn from the Clinformatics Data Mart. The analysis was restricted to individuals aged older than 50 years who received a prescription for a bone-directed therapy. The 15.48 million prescriptions evaluated were drawn from 1.46 million unique individuals. The mean age was 69 years, and 89% of those prescribed a drug were women.
Oncologic indications one of two tracked cohorts
In the context of a large expansion of treatment options in several drug classes for osteoporosis, the objective of this claims analysis was to document trends in treatment choice, according to Dr. Cromer. She and her coinvestigators looked at prescriptions overall as well as in two cohorts defined by ICD codes. One included patients prescribed a prescription by an oncologist. The other included everyone else.
When all prescriptions for bone-directed therapy were evaluated over the study period, alendronate was the most commonly prescribed therapy, and its use increased over time. Prescriptions of zoledronic acid also rose, doubling over the study period, but use was very low in the beginning and it never climbed above 5%.
The proportion of prescriptions written for bisphosphonates other than alendronate and zoledronic acid “declined steadily” over the study period, Dr. Cromer reported.
Denosumab, a monoclonal antibody that targets a step in the process important to maturation of osteoclasts, was approved in 2010. It accounted for 10% of all prescriptions for osteoporosis by 2015 and 15% by 2018. It was still rising through the end of the study period.
In contrast, prescriptions of raloxifene, a selective estrogen receptor modulator, began to decline after 2013. In general, the rates of prescriptions for other agents, including some of the more recently approved drugs, such as teriparatide, abaloparatide, and romosozumab, changed very little over the study period. None of these therapies ever represented more than 2% of prescriptions.
When looking at the cohort of patients who received a bone-directed reason for a noncancer indication, the trends “paralleled those in the all-user analysis,” Dr. Cromer reported.
Denosumab use greater in privately insured
In the malignancy cohort, the decline in the use of bisphosphonates and the rise in the use of denosumab were most pronounced in patients who were privately insured. The increased use of denosumab over the study period “outpaced gains in use of other agents despite guidelines,” said Dr. Cromer, referring to the those issued by the Endocrine Society in 2019 .
In those guidelines, written for management of postmenopausal women at high risk of fractures, bisphosphonates are recommended for initial treatment while denosumab is recommended as an alternative. However, those guidelines do not provide specific recommendations for therapies directed at osteoporosis associated with cancer.
Guidelines for this population exist, including one published by the American Society of Clinical Oncology in 2019.
In the ASCO guidelines, oral bisphosphonates, intravenous bisphosphonates, and subcutaneous denosumab were all identified as “efficacious options,” according to Charles L. Shapiro, MD, director of breast cancer translational research, Mount Sinai Health System, New York.
Specifically, “all three of them work to reduce fractures and improve bone density in women with breast cancer in whom you are trying to prevent or treat osteoporosis,” Dr. Shapiro said in an interview.
There might be relative advantages for one therapy over another in specific subgroups defined by type of cancer or stage of cancer, but trials are not definitive for such outcomes as overall survival. Citing one comparative study associating denosumab with an 18% delay to first skeletal event in women with metastatic breast cancer, Dr. Shapiro observed, “I personally don’t consider an 18% delay [for this outcome] to be that clinically meaningful.”
Although major guidelines from ASCO have not so far favored denosumab over any bisphosphonate in routine care, Dr. Shapiro did not rule out the possibility that future studies will show differences.
Dr. Comer and Dr. Shapiro reported no relevant conflicts of interest.
Amid a substantial expansion of therapies in several drug classes for the treatment of osteoporosis, there has been a notable increase in the prescription of denosumab for patients with a cancer-related indication.
In an analysis of claims data from January 2009 to March 2020, the bisphosphonate alendronate represented more than 50% of all prescriptions for bone-directed therapies, but growth in the use of the monoclonal antibody denosumab overall and in cancer-related indications particularly was steady throughout the study period.
“In the malignancy cohort, alendronate and zoledronic acid were each used in approximately 30% of individuals at the onset of the study, but use of both then declined,” Sara Cromer, MD, reported at the annual meeting of the Endocrine Society.
For malignancy-based prescriptions, denosumab surpassed either bisphosphonate by 2013 and then continued to rise.
Denosumab use “reached approximately 50% of all bone-directed medication use in the malignancy cohort” by the end of the study period, said Dr. Cromer, a clinical research fellow in endocrinology at Massachusetts General Hospital, Boston.
The claims data for this analysis was drawn from the Clinformatics Data Mart. The analysis was restricted to individuals aged older than 50 years who received a prescription for a bone-directed therapy. The 15.48 million prescriptions evaluated were drawn from 1.46 million unique individuals. The mean age was 69 years, and 89% of those prescribed a drug were women.
Oncologic indications one of two tracked cohorts
In the context of a large expansion of treatment options in several drug classes for osteoporosis, the objective of this claims analysis was to document trends in treatment choice, according to Dr. Cromer. She and her coinvestigators looked at prescriptions overall as well as in two cohorts defined by ICD codes. One included patients prescribed a prescription by an oncologist. The other included everyone else.

Combo thyroid hormones as good as levothyroxine for hypothyroidism
Patients with hypothyroidism treated with the three most common pharmacologic strategies of levothyroxine (LT4) alone, LT4 in combination with triiodothyronine (T3), or desiccated thyroid extract showed no differences in thyroid symptoms or secondary outcomes in a double-blind, randomized study.
“There are now proven good treatment options for the more than 1 in 10 patients with hypothyroidism who continue to experience symptoms of fatigue, mental fogginess, weight gain, and other symptoms despite taking levothyroxine,” first author Thanh Duc Hoang, DO, an endocrinologist at the Walter Reed National Military Medical Center, in Bethesda, Md., said in a press statement.
The findings were presented at the annual meeting of the Endocrine Society.
Commenting on the study, Alan P. Farwell, MD, said these new results are a valuable contribution to the understanding of treatment effects. “I think this is an interesting and important study and further studies are needed to clarify the optimal way to treat hypothyroidism,” said Dr. Farwell, who is director of endocrine clinics at Boston University.
Importantly, “the findings are different than studies where the patients are aware of what medication they are receiving,” he stressed in an interview, underscoring the importance of the double-blind design of the trial.
But Anne Cappola, MD, of the University of Pennsylvania, Philadelphia, pointed out that “the study was small and unlikely to have the statistical power to detect differences that could have been clinically important.”
Nevertheless, she too agreed that the double-blind study design is key: “My experience with patients is [the effects] are affected by patients’ perceptions about their thyroid medication. That is why studies designed so that patients do not know which treatment they are receiving are so important in this area.”
Randomized, double-blind comparison
Prior to the widespread availability of the current gold standard hypothyroidism treatment of LT4, the condition was typically treated with desiccated (animal) thyroid extract. And with many patients continuing to have a preference for this therapeutic approach, it is still commonly used.
Additionally, some patients treated with LT4 alone report greater improvements in symptoms with the addition of T3 – despite studies showing no benefits from the two together – leading to many clinicians commonly trying the combination approach.
To compare the efficacy of the three approaches in a prospective, double-blind, cross-over fashion, 75 patients received three therapeutic approaches each for 3 months: desiccated thyroid extract, an LT4/T3 combination, or LT4 alone.
After each 3-month treatment, patients completed a 36-point thyroid symptom questionnaire.
There was no significant differences in symptom relief, the primary outcome, between the three treatments (P = .32).
Overall, 45% of patients indicated they preferred desiccated thyroid as their first choice of treatment, 32% preferred LT4/T3 as their first choice, and 23% preferred LT4 alone.
For the secondary endpoints of weight, general health, depression (assessed using the Beck Depression Inventory), memory (Wechsler Memory Scale), lipids, and thyroid function, again, there were no significant differences between groups in any of the measures.
When switched to desiccated thyroid, many felt ‘much better’
A further exploratory analysis revealed that those who experienced symptoms while taking LT4 alone reported greater alleviation of symptoms with the other two treatments.
“As a whole group, there was no significant difference between the three treatment arms,” Dr. Hoang explained in an interview.
“However, with the subgroup analysis based on the scores of symptom questionnaires, we found that symptomatic patients on LT4 improved while being treated with LT4/T3 or desiccated thyroid,” he said.
Reports of improvements in switching to desiccated thyroid were notable, Dr. Hoang added. “Many patients when switched from LT4 to desiccated thyroid extract said they felt much better, [with] more energy, less mental fogginess, a better outlook, less flair of lupus symptoms, easier to lose weight, etc.”
The study also showed more patients with Hashimoto’s disease preferred desiccated thyroid extract and LT4/T3, compared with LT4 alone, however, the differences were not significant.
Treatment adjustments a helpful first step
Dr. Farwell noted that his approach when patients are still reporting symptoms despite LT4 treatment is to first try tweaking the dose.
“In my own practice, I prefer to adjust LT4 dosing first, and on occasion add T3, with a goal of getting both hormone levels in the upper half of the normal range,” he said. “I find that to be a better approach than desiccated thyroid extract. T3 should be taken twice a day due to its half-life.”
The approach is generally successful, he added. “Even those that come in asking for desiccated thyroid extract whom I am able to convince to try LT4/T3 end up being happy with their treatment in the end.
“The key is that you need to spend time discussing the options with patients and come to a consensus as to the therapy that will best resolve their symptoms and that they are most comfortable with,” he concluded.
In response to mounting evidence of different hypothyroidism treatment responses according to various subgroups of patients, experts recently called for the initiation of more thorough clinical trials on the issue of combination therapy, as recently reported by this news organization.
Dr. Hoang reported being a speaker for Acella Pharmaceuticals. Dr. Farwell and Dr. Cappola reported no relevant financial relationships.

ApoB may better predict mortality risk in statin-treated patients
A new study shows apolipoprotein B (apoB) and non-HDL cholesterol – but not LDL cholesterol – are associated with increased risk for all-cause mortality and myocardial infarction in patients taking statins.
Moreover, apoB was a more accurate marker of all-cause mortality risk than non-HDL or LDL cholesterol and was more accurate at identifying MI risk than LDL cholesterol.
“Any patient that comes to a doctor for evaluation, if statin treatment is sufficient, the doctor should look not only at LDL cholesterol but HDL cholesterol and apoB, if its available – that is the take-home message,” senior author Børge Grønne Nordestgaard, MD, DMSC, University of Copenhagen, said in an interview.
The findings are very relevant to clinical practice because international guidelines focus on LDL cholesterol and “many doctors are brainwashed that that is the only thing they should look at, just to keep LDL cholesterol down,” he said. “I’ve worked for years with triglyceride lipoproteins, what I call remnant cholesterol, and I think that the risk is very high also when you have high remnant cholesterol.”
Previous work has shown that apoB and non-HDL cholesterol better reflect atherosclerotic cardiovascular disease risk than LDL cholesterol. This is the first study, however, to show that elevated apoB and non-HDL cholesterol are associated with a higher risk for all-cause death in statin-treated patients with low LDL cholesterol, Dr. Nordestgaard noted.
The investigators compared outcomes among 13,015 statin-treated participants in the Copenhagen General Population Study using median baseline values of 92 mg/dL for apoB, 3.1 mmol/L (120 mg/dL) for non-HDL cholesterol, and 2.3 mmol/L (89 mg/dL) for LDL cholesterol. Over a median follow-up of 8 years, there were 2,499 deaths and 537 MIs.
As reported in the Journal of the American College of Cardiology, discordant apoB above the median with LDL cholesterol below was associated with a 21% increased risk for all-cause mortality (hazard ratio, 1.21; 95% confidence interval, 1.07-1.36) and 49% increased risk for MI (HR, 1.49; 95% CI, 1.15-1.92), compared with concordant apoB and LDL cholesterol below the medians.
Similar results were found for discordant non-HDL cholesterol above the median with low LDL cholesterol for all-cause mortality (HR, 1.18; 95% CI, 1.02-1.36) and MI (1.78; 95% CI, 1.35-2.34).
No such associations with mortality or MI were observed when LDL cholesterol was above the median and apoB or non-HDL below.
Additional analyses showed that high apoB with low non-HDL cholesterol was associated with a higher risk for all-cause mortality (HR, 1.21; 95% CI, 1.03-1.41), whereas high non-HDL cholesterol with low apoB was associated with a lower risk (HR, 0.75; 95% CI, 0.62-0.92).
Current guidelines define apoB greater than 130 mg/dL as a risk modifier in patients not using statins but, the authors wrote, “based on our results, the threshold for apoB as a risk modifier in statin-treated patients should be closer to 92 mg/dL than to 130 mg/dL.”
In an accompanying editorial, Neil J. Stone, MD, and Donald Lloyd-Jones, MD, both from Northwestern University, Chicago, said that American and European guidelines acknowledge the usefulness of apoB and non-HDL cholesterol in their risk algorithms and as possible targets to indicate efficacy, but don’t give a strong recommendation for apoB to assess residual risk.
“This paper suggests that, in the next iteration, we’ve got to give a stronger thought to measuring apoB for residual risk in those with secondary prevention,” Dr. Stone, vice chair of the 2018 American Heart Association/ACC cholesterol guidelines, said in an interview.
“The whole part of the guidelines was not to focus on any one number but to focus on the clinical risk as a whole,” he said. “You can enlarge your understanding of the patient by looking at their non-HDL, which you have anyway, and in certain circumstances, for example, people with metabolic syndrome, diabetes, obesity, or high triglycerides, those people might very well benefit from an apoB to further understand their risk. This paper simply highlights that and, therefore, was very valuable.”
Dr. Stone and Dr. Lloyd-Jones, however, pointed out that statin use was self-reported and information was lacking on adherence, dose intensity, and the amount of LDL cholesterol lowering from baseline. LDL cholesterol levels were also above current recommendations for optimizing risk reduction. “If statin dosing and LDL [cholesterol] were not optimized already, then there may have been ‘room’ for non-HDL [cholesterol] and apoB to add value in understanding residual risk,” they wrote.
The editorialists suggested that sequential use, rather than regular use, of apoB and non-HDL cholesterol may be best and that incorporating this information may be particularly beneficial for patients with metabolic disorders and elevated triglycerides after statin therapy.
“Maybe this paper is a wake-up call that there are other markers out there that can tell you that you still have higher risk and need to tighten up lifestyle and maybe be more adherent,” Dr. Stone said. “I think this is a wonderful chance to say that preventive cardiology isn’t just ‘set it and forget it’.”
C. Noel Bairey Merz, MD, who coauthored the 2018 cholesterol guidelines, agreed there’s “an overexuberant focus on LDL [cholesterol] for residual risk” and highlighted a recent systematic review of statins, ezetimibe, and PCSK9 cardiovascular outcomes trials that showed very little gain from aggressively driving down LDL below 100 mg/dL, unless the patient is at extremely high risk.
“If I, as a treating cardiologist who spends a lot of time on lipids, had a patient on a high-intensity statin and they didn’t drop [their LDL cholesterol] 50% and I already had them going to cardiac rehab and they were already losing weight, would I measure apoB? Yeah, I might, to motivate them to do more or to take Vascepa,” she said.
“This study is a useful addition to a relatively important problem, which is residual risk, and really supports personalized or precision medicine,” added Bairey Merz, MD, Cedars-Sinai Medical Center, Los Angeles. “But now we have to do the work and do an intervention trial in these people and see whether these markers make a difference.”
The study was supported by Herlev and Gentofte Hospital’s Research Fund and the department of clinical biochemistry, Herlev and Gentofte Hospital, Copenhagen University Hospital. Dr. Nordestgaard has had consultancies or talks sponsored by AstraZeneca, Sanofi, Regeneron, Akcea, Amarin, Amgen, Esperion, Kowa, Novartis, Novo Nordisk, and Silence Therapeutics. All other authors, Dr. Stone, and Dr. Lloyd-Jones reported no conflicts. Dr. Merz reported no relevant disclosures.

A new study shows apolipoprotein B (apoB) and non-HDL cholesterol – but not LDL cholesterol – are associated with increased risk for all-cause mortality and myocardial infarction in patients taking statins.
Moreover, apoB was a more accurate marker of all-cause mortality risk than non-HDL or LDL cholesterol and was more accurate at identifying MI risk than LDL cholesterol.
“Any patient that comes to a doctor for evaluation, if statin treatment is sufficient, the doctor should look not only at LDL cholesterol but HDL cholesterol and apoB, if its available – that is the take-home message,” senior author Børge Grønne Nordestgaard, MD, DMSC, University of Copenhagen, said in an interview.
The findings are very relevant to clinical practice because international guidelines focus on LDL cholesterol and “many doctors are brainwashed that that is the only thing they should look at, just to keep LDL cholesterol down,” he said. “I’ve worked for years with triglyceride lipoproteins, what I call remnant cholesterol, and I think that the risk is very high also when you have high remnant cholesterol.”
Previous work has shown that apoB and non-HDL cholesterol better reflect atherosclerotic cardiovascular disease risk than LDL cholesterol. This is the first study, however, to show that elevated apoB and non-HDL cholesterol are associated with a higher risk for all-cause death in statin-treated patients with low LDL cholesterol, Dr. Nordestgaard noted.
The investigators compared outcomes among 13,015 statin-treated participants in the Copenhagen General Population Study using median baseline values of 92 mg/dL for apoB, 3.1 mmol/L (120 mg/dL) for non-HDL cholesterol, and 2.3 mmol/L (89 mg/dL) for LDL cholesterol. Over a median follow-up of 8 years, there were 2,499 deaths and 537 MIs.
As reported in the Journal of the American College of Cardiology, discordant apoB above the median with LDL cholesterol below was associated with a 21% increased risk for all-cause mortality (hazard ratio, 1.21; 95% confidence interval, 1.07-1.36) and 49% increased risk for MI (HR, 1.49; 95% CI, 1.15-1.92), compared with concordant apoB and LDL cholesterol below the medians.
Similar results were found for discordant non-HDL cholesterol above the median with low LDL cholesterol for all-cause mortality (HR, 1.18; 95% CI, 1.02-1.36) and MI (1.78; 95% CI, 1.35-2.34).
No such associations with mortality or MI were observed when LDL cholesterol was above the median and apoB or non-HDL below.
Additional analyses showed that high apoB with low non-HDL cholesterol was associated with a higher risk for all-cause mortality (HR, 1.21; 95% CI, 1.03-1.41), whereas high non-HDL cholesterol with low apoB was associated with a lower risk (HR, 0.75; 95% CI, 0.62-0.92).
Current guidelines define apoB greater than 130 mg/dL as a risk modifier in patients not using statins but, the authors wrote, “based on our results, the threshold for apoB as a risk modifier in statin-treated patients should be closer to 92 mg/dL than to 130 mg/dL.”
In an accompanying editorial, Neil J. Stone, MD, and Donald Lloyd-Jones, MD, both from Northwestern University, Chicago, said that American and European guidelines acknowledge the usefulness of apoB and non-HDL cholesterol in their risk algorithms and as possible targets to indicate efficacy, but don’t give a strong recommendation for apoB to assess residual risk.
“This paper suggests that, in the next iteration, we’ve got to give a stronger thought to measuring apoB for residual risk in those with secondary prevention,” Dr. Stone, vice chair of the 2018 American Heart Association/ACC cholesterol guidelines, said in an interview.
“The whole part of the guidelines was not to focus on any one number but to focus on the clinical risk as a whole,” he said. “You can enlarge your understanding of the patient by looking at their non-HDL, which you have anyway, and in certain circumstances, for example, people with metabolic syndrome, diabetes, obesity, or high triglycerides, those people might very well benefit from an apoB to further understand their risk. This paper simply highlights that and, therefore, was very valuable.”
Dr. Stone and Dr. Lloyd-Jones, however, pointed out that statin use was self-reported and information was lacking on adherence, dose intensity, and the amount of LDL cholesterol lowering from baseline. LDL cholesterol levels were also above current recommendations for optimizing risk reduction. “If statin dosing and LDL [cholesterol] were not optimized already, then there may have been ‘room’ for non-HDL [cholesterol] and apoB to add value in understanding residual risk,” they wrote.
The editorialists suggested that sequential use, rather than regular use, of apoB and non-HDL cholesterol may be best and that incorporating this information may be particularly beneficial for patients with metabolic disorders and elevated triglycerides after statin therapy.
“Maybe this paper is a wake-up call that there are other markers out there that can tell you that you still have higher risk and need to tighten up lifestyle and maybe be more adherent,” Dr. Stone said. “I think this is a wonderful chance to say that preventive cardiology isn’t just ‘set it and forget it’.”

Cannabinoids promising for improving appetite, behavior in dementia
For patients with dementia, cannabinoids may be a promising intervention for treating neuropsychiatric symptoms (NPS) and the refusing of food, new research suggests.
Results of a systematic literature review, presented at the 2021 meeting of the American Association for Geriatric Psychiatry, showed that cannabinoids were associated with reduced agitation, longer sleep, and lower NPS. They were also linked to increased meal consumption and weight gain.
Refusing food is a common problem for patients with dementia, often resulting in worsening sleep, agitation, and mood, study investigator Niraj Asthana, MD, a second-year resident in the department of psychiatry, University of California, San Diego, said in an interview. Dr. Asthana noted that certain cannabinoid analogues are now used to stimulate appetite for patients undergoing chemotherapy.
Filling a treatment gap
After years of legal and other problems affecting cannabinoid research, there is renewed interest in investigating its use for patients with dementia. Early evidence suggests that cannabinoids may also be beneficial for pain, sleep, and aggression.
The researchers noted that cannabinoids may be especially valuable in areas where there are currently limited therapies, including food refusal and NPS.
“Unfortunately, there are limited treatments available for food refusal, so we’re left with appetite stimulants and electroconvulsive therapy, and although atypical antipsychotics are commonly used to treat NPS, they’re associated with an increased risk of serious adverse events and mortality in older patients,” said Dr. Asthana.
Dr. Asthana and colleague Dan Sewell, MD, carried out a systematic literature review of relevant studies of the use of cannabinoids for dementia patients.
“We found there are lot of studies, but they’re small scale; I’d say the largest was probably about 50 patients, with most studies having 10-50 patients,” said Dr. Asthana. In part, this may be because, until very recently, research on cannabinoids was controversial.
To review the current literature on the potential applications of cannabinoids in the treatment of food refusal and NPS in dementia patients, the researchers conducted a literature review.
They identified 23 relevant studies of the use of synthetic cannabinoids, including dronabinol and nabilone, for dementia patients. These products contain tetrahydrocannabinol (THC), the main psychoactive compound in cannabis.
More research coming
Several studies showed that cannabinoid use was associated with reduced nighttime motor activity, improved sleep duration, reduced agitation, and lower Neuropsychiatric Inventory scores.
One crossover placebo-controlled trial showed an overall increase in body weight among dementia patients who took dronabinol.
This suggests there might be something to the “colloquial cultural association between cannabinoids and the munchies,” said Dr. Asthana.
Possible mechanisms for the effects on appetite may be that cannabinoids increase levels of the hormone ghrelin, which is also known as the “hunger hormone,” and decrease leptin levels, a hormone that inhibits hunger. Dr. Asthana noted that, in these studies, the dose of THC was low and that overall, cannabinoids appeared to be safe.
“We found that, at least in these small-scale studies, cannabinoid analogues are well tolerated,” possibly because of the relatively low doses of THC, said Dr. Asthana. “They generally don’t seem to have a ton of side effects; they may make people a little sleepy, which is actually good, because these patents also have a lot of trouble sleeping.”
He noted that more recent research suggests cannabidiol oil may reduce agitation by up to 40%.
“Now that cannabis is losing a lot of its stigma, both culturally and in the scientific community, you’re seeing a lot of grant applications for clinical trials,” said Dr. Asthana. “I’m excited to see what we find in the next 5-10 years.”
In a comment, Kirsten Wilkins, MD, associate professor of psychiatry, Yale University, New Haven, Conn., who is also a geriatric psychiatrist at the Veterans Affairs Connecticut Health Care System, welcomed the new research in this area.
“With limited safe and effective treatments for food refusal and neuropsychiatric symptoms of dementia, Dr. Asthana and Dr. Sewell highlight the growing body of literature suggesting cannabinoids may be a novel treatment option,” she said.

Melatonin not recommended for early-stage NSCLC
There was a hint of benefit with melatonin among patients with stage III/IV NSCLC. These patients had a hazard reduction of 25% in 5-year DFS. However, the median DFS for patients with advanced disease was the same whether they received melatonin or placebo – 18 months.
In the overall study population, melatonin had no beneficial effects on quality of life, sleep, anxiety, depression, pain, or fatigue, and it did not reduce adverse events from chemotherapy or radiation.
These results were reported in EClinicalMedicine.
“In light of the results, we do not recommend the inclusion of adjuvant melatonin for patients with early-stage NSCLC. Evidence suggests there may be a benefit for those with late-stage disease,” the authors wrote. “However, because of the mixed findings observed, we recommend a follow-up randomized, controlled trial involving a larger population focusing on later-stage resected lung cancer to clarify these results.”
“I would very much like to pursue another controlled study of melatonin specifically in a group of late-stage lung cancer and possibly in other more advanced cancer types,” said lead author Dugald Seely, ND, of the Canadian College of Naturopathic Medicine in Toronto.
Study rationale and design
Melatonin has shown promise for treating patients with lung cancer, Dr. Seely and colleagues noted. Melatonin is often recommended by naturopathic doctors following lung cancer surgery, but until now there was no high-level evidence regarding the practice.
For their study, Dr. Seely and colleagues evaluated 709 patients who had undergone NSCLC resection. The patients were randomized to receive placebo (n = 353) or melatonin (n = 356) 1 hour before bedtime for 1 year. A 20-mg melatonin dose was used, which is common in clinical practice and research.
The study arms were well matched, with no “clinically meaningful” differences in demographics, surgery type, cancer type, stage of cancer, or preoperative comorbidities, according to the researchers.
The mean age in both treatment arms was 67 years. Overall, 134 participants received adjuvant chemotherapy (66 melatonin, 68 placebo), and 43 had adjuvant radiation (22 melatonin, 21 placebo).
Results
For 2-year DFS, melatonin showed an adjusted relative risk of 1.01 (95% confidence interval, 0.83-1.22; P = .94) versus placebo. The adjusted relative risk in the per-protocol analysis was 1.12 (95% CI, 0.96-1.32; P = .14.)
At 5 years, the median DFS was not reached in either treatment arm. Melatonin showed a hazard ratio of 0.97 (95% CI, 0.86-1.09; P = .84) for 5-year DFS.
Among patients with stage I-II NSCLC, the median DFS was not reached at 5 years in either treatment arm. Among patients with stage III-IV NSCLC, the median DFS was 18 months in both arms.
Melatonin showed a hazard ratio of 0.97 (95% CI, 0.85-1.11; P = .66) in patients with early-stage NSCLC and a hazard reduction of 25% (HR, 0.75; 95% CI, 0.61-0.92; P = .005) in patients with late-stage NSCLC.
For the entire cohort, there were no significant differences between treatment arms in the number, severity, or seriousness of adverse events. Likewise, there were no significant differences between the treatment arms with regard to fatigue, quality of life, or sleep at 1 or 2 years.
Dr. Seely said the most surprising thing about this study was that melatonin didn’t help with sleep.
“Since initiation of the trial, my thinking on the right dose of melatonin to support sleep has changed. Clinically, I see extended-release and, indeed, lower doses to be more effective than 20 mg nightly,” he noted.
Dr. Seely and colleagues also assessed proposed mechanisms for melatonin’s possible benefit in NSCLC but found no effect on natural killer cell cytotoxicity or phenotype and no effect on blood levels of inflammatory cytokines in a substudy of 92 patients.
This research was funded by the Lotte and John Hecht Memorial Foundation and the Gateway for Cancer Research Foundation. The researchers had no relevant disclosures.

Among patients with stage I-II NSCLC, the median DFS was not reached at 5 years in either treatment arm. Among patients with stage III-IV NSCLC, the median DFS was 18 months in both arms.
Melatonin showed a hazard ratio of 0.97 (95% CI, 0.85-1.11; P = .66) in patients with early-stage NSCLC and a hazard reduction of 25% (HR, 0.75; 95% CI, 0.61-0.92; P = .005) in patients with late-stage NSCLC.
For the entire cohort, there were no significant differences between treatment arms in the number, severity, or seriousness of adverse events. Likewise, there were no significant differences between the treatment arms with regard to fatigue, quality of life, or sleep at 1 or 2 years.
Dr. Seely said the most surprising thing about this study was that melatonin didn’t help with sleep.
“Since initiation of the trial, my thinking on the right dose of melatonin to support sleep has changed. Clinically, I see extended-release and, indeed, lower doses to be more effective than 20 mg nightly,” he noted.
Dr. Seely and colleagues also assessed proposed mechanisms for melatonin’s possible benefit in NSCLC but found no effect on natural killer cell cytotoxicity or phenotype and no effect on blood levels of inflammatory cytokines in a substudy of 92 patients.

There was a hint of benefit with melatonin among patients with stage III/IV NSCLC. These patients had a hazard reduction of 25% in 5-year DFS. However, the median DFS for patients with advanced disease was the same whether they received melatonin or placebo – 18 months.
In the overall study population, melatonin had no beneficial effects on quality of life, sleep, anxiety, depression, pain, or fatigue, and it did not reduce adverse events from chemotherapy or radiation.
These results were reported in EClinicalMedicine.
“In light of the results, we do not recommend the inclusion of adjuvant melatonin for patients with early-stage NSCLC. Evidence suggests there may be a benefit for those with late-stage disease,” the authors wrote. “However, because of the mixed findings observed, we recommend a follow-up randomized, controlled trial involving a larger population focusing on later-stage resected lung cancer to clarify these results.”
“I would very much like to pursue another controlled study of melatonin specifically in a group of late-stage lung cancer and possibly in other more advanced cancer types,” said lead author Dugald Seely, ND, of the Canadian College of Naturopathic Medicine in Toronto.
Study rationale and design
Melatonin has shown promise for treating patients with lung cancer, Dr. Seely and colleagues noted. Melatonin is often recommended by naturopathic doctors following lung cancer surgery, but until now there was no high-level evidence regarding the practice.
For their study, Dr. Seely and colleagues evaluated 709 patients who had undergone NSCLC resection. The patients were randomized to receive placebo (n = 353) or melatonin (n = 356) 1 hour before bedtime for 1 year. A 20-mg melatonin dose was used, which is common in clinical practice and research.
The study arms were well matched, with no “clinically meaningful” differences in demographics, surgery type, cancer type, stage of cancer, or preoperative comorbidities, according to the researchers.
The mean age in both treatment arms was 67 years. Overall, 134 participants received adjuvant chemotherapy (66 melatonin, 68 placebo), and 43 had adjuvant radiation (22 melatonin, 21 placebo).
