Pharmacology

Orally dissolving medications containing buprenorphine are linked to severe dental problems, including total tooth loss, the U.S. Food and Drug Administration warns in a safety communication.

The oral side effects of these medications, which are used to treat opioid use disorder (OUD) and pain, include cavities/tooth decay, including rampant caries; dental abscesses/infection; tooth erosion; fillings falling out; and, in some cases, total tooth loss.

More than 300 reported cases

Buprenorphine was approved in 2002 as a sublingual tablet, and in 2015 as a film to be placed inside the cheek to treat pain. Both delivery methods have been associated with dental problems.

Since buprenorphine was approved, the FDA has identified 305 cases of dental problems associated with orally dissolving buprenorphine, including 131 classified as serious.

There may be other cases, the FDA says, as this represents only cases reported to the FDA or published in the medical literature.

The average age of the patients who developed dental problems while taking buprenorphine is 42 years, but those as young as 18 years old were also affected.

Most cases occurred in patients using the medicines for OUD; however, 28 cases of dental problems occurred in patients using it to treat pain.

In 26 cases, patients had no prior history of dental problems. Some dental problems developed as soon as 2 weeks after treatment began; the median time to diagnosis was about 2 years after starting treatment.

Among all 305 cases reported, 113 involved two or more teeth.

The most common treatment for the dental problems was tooth extraction/removal, which was reported in 71 cases. Other cases required root canals, dental surgery, and other procedures such as crowns and implants.
 

Recommendations

The FDA says health care providers should counsel patients that severe and extensive tooth decay, tooth loss, and tooth fracture have been reported with the use of transmucosal buprenorphine-containing medicines and emphasize the importance of visiting their dentist to closely monitor their teeth.

Patients should be counseled to continue taking buprenorphine medications as prescribed and not stop suddenly without first talking to their health care provider, as this could lead to serious consequences, including relapse, misuse or abuse of other opioids, overdose, and death.

Patients are also being advised to take extra steps to help lessen the risk of serious dental problems.

Patients should also be educated on strategies to maintain or improve oral health while taking transmucosal buprenorphine medicines.

Counsel them that after the medicine is completely dissolved, the patient should take a large sip of water, swish it gently around the teeth and gums, swallow, and wait at least 1 hour before brushing their teeth, as the FDA advises. This will allow time for the mouth to gradually return to oral homeostasis and avoid any mechanical damage that may occur due to brushing.

The FDA also advises that patients tell their provider about any history of tooth problems, including cavities, and schedule a dentist visit soon after starting the medicine.

Dental problems related to transmucosal buprenorphine-containing medicines should be reported to the FDA’s MedWatch program.

Almost 90% of treatment naive chronic lymphocytic leukemia/small lymphocytic lymphoma patients (33/37) had undetectable minimal residual disease (MRD) in both blood and bone marrow when the second-generation Bruton’s tyrosine kinase (BTK) inhibitor zanubrutinib (Brukinsa) was added on to obinutuzumab and venetoclax for a median of just 10 treatment cycles.

Treatment was stopped in the single-arm phase 2 trial when patients reached undetectable MRD, a novel use of MRD to guide treatment duration. At a median of 16 months after discontinuation, MRD remained undetectable in 31 of 33 patients (94%).

The team also found that a reduction to 1/400 of baseline MRD (delta-MRD400) by day 1 of cycle five predicted undetectable bone marrow MRD within eight treatment cycles.

delta-MRD400 is “a potential biomarker” to identify patients who’ll do well with a shorter treatment and flag others who require longer courses of therapy, said investigators led by Jacob Soumerai, MD, a hematologist/oncologist at Massachusetts General Hospital, Boston.

Overall, the results “are highly encouraging,” they said, with efficacy and safety comparing favorably to trials that added other BTK inhibitors – namely ibrutinib and acalabrutinib – to the standard obinutuzumab/venetoclax backbone, with a shorter treatment duration.

They said the novel triplet warrants further study in the first line and noted that they also “plan to prospectively validate early-MRD-response kinetics as a biomarker to guide treatment duration.” The study was published recently in The Lancet Haematology.

Two editorialists – Davide Rossi, MD, PhD, and Joyce Marques De Almeida, both of the of the Oncology Institute of Southern Switzerland, Bellinzona – were encouraged by the findings and wanted future research to assess how well MRD-guided treatment duration works in patients with tumor protein p53-disrupted disease, who “benefit less from time-limited therapies” then patients with wild-type TP53; the trial was too small to address the issue.

There was a two-cycle lead-in with zanubrutinib and obinutuzumab then venetoclax ramp-up starting at cycle 3, with each cycle running 28 days.

Zanubrutinib is approved in the U.S. for mantle cell lymphoma, Waldenström’s macroglobulinemia, and marginal zone lymphoma.

In a previous phase 2 trial of ibrutinib add-on to venetoclax-obinutuzumab for 14 cycles followed by ibrutinib monotherapy, the rate of undetectable MRD in both peripheral blood and bone marrow was 67%. The rate of bone marrow undetectable MRD was 77% in another phase 2 trial of acalabrutinib, venetoclax, and obinutuzumab for at least 15 cycles.

Dr. Soumerai and his team cautioned, however, that “comparisons across trials are fraught with selection bias resulting in differences in treated patient populations, and randomized data are needed to establish the optimal BTK inhibitor to combine with venetoclax with or without obinutuzumab, and to establish whether” the zanubrutinib triplet “improves progression-free survival and overall survival compared with current standard first-line therapy.”

There was grade 3 or worse neutropenia in 18% of subjects (7/39), one episode of febrile neutropenia (3%), lung infections in three patients (8%) patients, and five cases of hypertension (13%).

The editorialists characterized the numbers as low and the regimen as well tolerated. Past studies of ibrutinib, a first generation BTK, with venetoclax and obinutuzumab have pegged grade 3 or worse neutropenia at 56% and the hypertension incidence at 48%.

Granulocyte colony-stimulating factor administration “could partially account for the low incidence of severe neutropenia” in the trial, the investigators said.

The study was funded by zanubrutinib marketer Beigene as well as Genentech, the National Cancer Institute, and others. Many of the authors had industry ties, including Dr. Soumerai who reported being a consultant and researcher for Beigene and other companies. Dr. Rossi reported honoraria and research grants from AbbVie, AstraZeneca, and Janssen.

The risk of myocarditis after immunization with mRNA-based vaccines against SARS-CoV-2 raised concerns when it came to light in early 2021. But as report after report showed such cases to be rare and usually mild and self-limited, focus has turned to the “how and why.”  

The mechanism linking the BNT162b2 (Pfizer-BioNTech) and especially mRNA-1273 (Moderna) vaccines to the occurrence of myocarditis is unclear for now, but one potential driver may be tied to a peculiarity that became apparent early: It occurs overwhelmingly in younger males, from 16 to perhaps 40 or 50 years of age. Excess risk has not been consistently seen among women, girls, and older men.

That observation has led to speculation that higher testosterone levels in adolescent boys and young men may somehow promote the adverse vaccine effect, whereas greater levels of estrogen among girls and women in the same age range may be cardioprotective.
 

Unlikely, brief, and ‘benign’

“Most of the myocarditis is benign, by which I mean that maybe the patients are admitted due to chest pain, but without reduction in ventricular function,” Enrico Ammirati, MD, PhD, a myocarditis expert at De Gasperis Cardio Center and Transplant Center, Niguarda Hospital, Milan, said in an interview.

In a Nov. 14 address on this topic at the annual scientific sessions of the American Heart Association, Dror Mevorach, MD, described the typical case presentation as “mild” and one that clears in fairly short order based on resolution of “clinical symptoms, inflammatory markers and troponin decline, EKG normalization, echo normalization, and a relatively short length of hospital stay.”

Dr. Mevorach, of Hadassah Hebrew University Medical Center, Jerusalem, subsequently published the findings in a report in the New England Journal of Medicine that described 136 confirmed myocarditis cases among more than 5 million people in Israel immunized with the Pfizer-BioNTech vaccine. Myocarditis was considered “mild” in 129 cases, or 95%.

And the risk is tiny, compared with myocarditis from infection by SARS-CoV-2, not to mention the possibility of nasty clinical COVID-19 complications such as pneumonia and pulmonary embolism, Dr. Mevorach observed.

Many other reports agree that the incidence is minimal, especially given the rewards of vaccination. In a separate NEJM publication in September 2021 – from Noam Barda, MD, Clalit (Israel) Research Institute, and colleagues on 1.7 million people in that country, about half unvaccinated and half given the Pfizer-BioNTech vaccine – there were an estimated 2.7 cases of  myocarditis per 100,000 vaccinated persons. There were also 11 cases of myocarditis per 100,000 persons who were positive for SARS-CoV-2 infection.

And in a recent case series of vaccinated people aged 16 or older, the myocarditis rate after a first or second Pfizer-BioNTech or Moderna injection was estimated at 1 or fewer per 100,000. The corresponding estimate was 4 such cases per 100,000 after a positive SARS-CoV-2 test among the same population, notes a report published Dec.14, 2021, in Nature Medicine.

In general, “the risk of any kind of cardiac injury is vastly lower with a vaccine than it is with the actual viral infection,” Leslie T. Cooper Jr., MD, a myocarditis expert and clinical trialist at the Mayo Clinic, Jacksonville, Fla., said in an interview. With the mRNA-based vaccines, “we do not have any conceivable danger signal that would outweigh the benefit of vaccination.”
 

Males of a certain age

Evidence that such myocarditis predominates in young adult men and adolescent boys, especially following a second vaccine dose, is remarkably consistent.

The risk was elevated only among mRNA-based vaccine recipients who were younger than 40 in the recent Nature Medicine analysis. Among that group, estimates after a second dose numbered fewer than 1 case per 100,000 for Pfizer-BioNTech and 1.5 per 100,000 for Moderna.

In a third analysis from Israel – also in NEJM, from Guy Witberg, MD, Rabin Medical Center, Petah Tikva, and colleagues, based on 2.5 million people aged 16 and older with at least one Pfizer-BioNTech injection – 2.1 cases per 100,000 were estimated overall, but the number rose to 10.7 per 100,000 among those aged 16-29 years.

In Dr. Mevorach’s NEJM report, estimates after a second Pfizer-BioNTech vaccine dose were 1 per 26,000 males versus 1 in 218,000 females, compared with 1 myocarditis case in 10,857 persons among “the general unvaccinated population.”

Most recipients of a first vaccine dose were younger than 50, and 16- to 29-year-olds accounted for most who completed two doses, noted Dr. Mevorach. Younger males bore the brunt of any myocarditis: the estimated prevalence after a second dose among males aged 16-19 was 1 per 6,637, compared with 1 per 99,853 females in the same age range, the group reported.

In the BMJ report, based on about 5 million people 12 years of age or older in Denmark, the estimated rates of myocarditis or pericarditis associated with Moderna immunization were 2 per 100,000 among women but 6.3 per 100,000 for men. The incidence and sex difference was much lower among those getting the Pfizer-BioNTech vaccine: 1.3 per 100,000 and 1.5 per 100,000 in women and men, respectively.
 

Sex hormones may be key

The predominance of vaccine-associated myocarditis among adolescent and young adult males is probably more about the myocarditis itself than the vaccines, observed Biykem Bozkurt, MD, PhD, who has been studying COVID-related myocarditis at Baylor College of Medicine, Houston.

Male sex historically is associated in both epidemiologic studies and experimental models with a greater propensity for most any form of myocarditis, Dr. Bozkurt said in an interview. Given that males aged 16-19 or so appear to be at highest risk of myocarditis as a complication of SARS-CoV-2 vaccination, the mechanism may well be related to sex hormones.  

“Therefore, testosterone is implicated as a player in their higher risk of inflammation and injury and lack of adaptive response in terms of healing, and in terms of prevention of injury,” Dr. Bozkurt said. For its part, estrogen inhibits proinflammatory processes and, in particular, “blunts cell-mediated immune responses.”

“We don’t know the mechanism, but a theory that attributes a protective role to estrogen, or a risk associated with testosterone, is reasonable. It makes sense, at least based on epidemiological data,” Dr. Ammirati agreed. Still, “we do not have any direct evidence in human beings.”

Sex-associated differences in experimental myocarditis have been reported in the journals for at least 70 years, but “the testosterone literature and the estrogen literature have not been evaluated in detail in vaccine-associated myocarditis,” Dr. Cooper said.

Most myocarditis in the laboratory is viral, Dr. Cooper observed, and “the links between testosterone, viruses, and inflammation have been pretty well worked out, I would say, if you’re a mouse. If you’re a human, I think it’s still a bit uncertain.”

Were it to apply in humans, greater testosterone levels might independently promote myocarditis, “and if estrogen is cardioprotective, it would be another mechanism,” Dr. Cooper said. “That would translate to slight male predominance in most kinds of myocarditis.”

In males, compared with females, “the heart can be more vulnerable to events such as arrhythmias or to immune-mediated phenomena. So, probably there is also higher vulnerability to myocarditis in men,” Dr. Ammirati noted.

Male predominance in vaccine-related myocarditis is provocative, so it’s worth considering whether testosterone is part of the mechanism as well as the possibility of estrogen cardioprotection, Dr. Ammirati said. But given limitations of the animal models, “we don’t really have robust data to support any part of that.”

Although myocarditis is in some way immune mediated, “and hormones can modulate the response,” the mechanism has to be more than just sex hormones, he said. “They probably cannot explain the specificity for the heart. It’s not a systemic response, it’s an organ-specific response.”
 

Modulation of immune responses

Details about the immune processes underlying mRNA-vaccine myocarditis, hormone modulated or not, have been elusive. The complication doesn’t resemble serum sickness, nor does it seem to be a reaction to infection by other cardiotropic viruses, such as coxsackie virus B, a cause of viral myocarditis, Dr. Bozkurt said. The latter had been a compelling possibility because such hypersensitivity to smallpox vaccination is well recognized.

“We don’t know the mechanism, that’s the short answer. But there are many hypotheses,” she said. One candidate widely proposed in the literature: autoantibodies driven by molecular mimicry between the SARS-CoV-2 spike protein targeted by the mRNA vaccines and a structurally similar myocardial protein, possibly alpha-myosin, noted Dr. Bozkurt and colleagues in a recent publication.

But elevations in specific “antiheart antibodies” have not been documented in recipients of the two mRNA-based vaccines, said Dr. Cooper. “So, I would say that – although molecular mimicry is a well-established mechanism of, for example, rheumatic carditis after a streptococcal A infection – that has not been demonstrated yet for COVID-19 mRNA vaccination–related myocarditis.”

“We probably won’t know, ever, with a huge level of certainty, the exact mechanisms,” Dr. Cooper added. There is no animal model for vaccine-induced myocarditis, and “We’re still talking very, very small numbers of patients. The vast majority of them recover,” and so don’t generally provide mechanistic clues.  
 

Prospects for younger children

Vaccination against SARS-CoV-2 has now been authorized by the Centers for Disease Control and Prevention for kids as young as 5-11 years, using the Pfizer-BioNTech vaccine. Experience so far suggests the immunization is safe in that age group with negligible risk of myocarditis or other complications. But with prospects of possible authorization in children younger than 5, should myocarditis be a concern for them?

Probably not, if the complication is driven primarily by sex hormones, Dr. Cooper proposed. “One would predict that before puberty you would have a lower – much, much lower – rate of myocarditis in males than you would in the 16- to 19-year-old range, and that it would be roughly equal to females.” Dr. Ammirati and Dr. Bozkurt largely agreed.

It remains to be seen whether the vaccine-related myocarditis risk applies to children younger than 12, “but I doubt it. I think it’s going to be puberty-related,” Dr. Bozkurt said. Still, “I don’t want to hypothesize without data.”

In a Nov. 14 address on this topic at the annual scientific sessions of the American Heart Association, Dror Mevorach, MD, described the typical case presentation as “mild” and one that clears in fairly short order based on resolution of “clinical symptoms, inflammatory markers and troponin decline, EKG normalization, echo normalization, and a relatively short length of hospital stay.”

Dr. Mevorach, of Hadassah Hebrew University Medical Center, Jerusalem, subsequently published the findings in a report in the New England Journal of Medicine that described 136 confirmed myocarditis cases among more than 5 million people in Israel immunized with the Pfizer-BioNTech vaccine. Myocarditis was considered “mild” in 129 cases, or 95%.

And the risk is tiny, compared with myocarditis from infection by SARS-CoV-2, not to mention the possibility of nasty clinical COVID-19 complications such as pneumonia and pulmonary embolism, Dr. Mevorach observed.

Many other reports agree that the incidence is minimal, especially given the rewards of vaccination. In a separate NEJM publication in September 2021 – from Noam Barda, MD, Clalit (Israel) Research Institute, and colleagues on 1.7 million people in that country, about half unvaccinated and half given the Pfizer-BioNTech vaccine – there were an estimated 2.7 cases of  myocarditis per 100,000 vaccinated persons. There were also 11 cases of myocarditis per 100,000 persons who were positive for SARS-CoV-2 infection.

And in a recent case series of vaccinated people aged 16 or older, the myocarditis rate after a first or second Pfizer-BioNTech or Moderna injection was estimated at 1 or fewer per 100,000. The corresponding estimate was 4 such cases per 100,000 after a positive SARS-CoV-2 test among the same population, notes a report published Dec.14, 2021, in Nature Medicine.

In general, “the risk of any kind of cardiac injury is vastly lower with a vaccine than it is with the actual viral infection,” Leslie T. Cooper Jr., MD, a myocarditis expert and clinical trialist at the Mayo Clinic, Jacksonville, Fla., said in an interview. With the mRNA-based vaccines, “we do not have any conceivable danger signal that would outweigh the benefit of vaccination.”
 

Males of a certain age

Evidence that such myocarditis predominates in young adult men and adolescent boys, especially following a second vaccine dose, is remarkably consistent.

The risk was elevated only among mRNA-based vaccine recipients who were younger than 40 in the recent Nature Medicine analysis. Among that group, estimates after a second dose numbered fewer than 1 case per 100,000 for Pfizer-BioNTech and 1.5 per 100,000 for Moderna.

In a third analysis from Israel – also in NEJM, from Guy Witberg, MD, Rabin Medical Center, Petah Tikva, and colleagues, based on 2.5 million people aged 16 and older with at least one Pfizer-BioNTech injection – 2.1 cases per 100,000 were estimated overall, but the number rose to 10.7 per 100,000 among those aged 16-29 years.

In Dr. Mevorach’s NEJM report, estimates after a second Pfizer-BioNTech vaccine dose were 1 per 26,000 males versus 1 in 218,000 females, compared with 1 myocarditis case in 10,857 persons among “the general unvaccinated population.”

Most recipients of a first vaccine dose were younger than 50, and 16- to 29-year-olds accounted for most who completed two doses, noted Dr. Mevorach. Younger males bore the brunt of any myocarditis: the estimated prevalence after a second dose among males aged 16-19 was 1 per 6,637, compared with 1 per 99,853 females in the same age range, the group reported.

In the BMJ report, based on about 5 million people 12 years of age or older in Denmark, the estimated rates of myocarditis or pericarditis associated with Moderna immunization were 2 per 100,000 among women but 6.3 per 100,000 for men. The incidence and sex difference was much lower among those getting the Pfizer-BioNTech vaccine: 1.3 per 100,000 and 1.5 per 100,000 in women and men, respectively.
 

Sex hormones may be key

The predominance of vaccine-associated myocarditis among adolescent and young adult males is probably more about the myocarditis itself than the vaccines, observed Biykem Bozkurt, MD, PhD, who has been studying COVID-related myocarditis at Baylor College of Medicine, Houston.

Male sex historically is associated in both epidemiologic studies and experimental models with a greater propensity for most any form of myocarditis, Dr. Bozkurt said in an interview. Given that males aged 16-19 or so appear to be at highest risk of myocarditis as a complication of SARS-CoV-2 vaccination, the mechanism may well be related to sex hormones.  

“Therefore, testosterone is implicated as a player in their higher risk of inflammation and injury and lack of adaptive response in terms of healing, and in terms of prevention of injury,” Dr. Bozkurt said. For its part, estrogen inhibits proinflammatory processes and, in particular, “blunts cell-mediated immune responses.”

“We don’t know the mechanism, but a theory that attributes a protective role to estrogen, or a risk associated with testosterone, is reasonable. It makes sense, at least based on epidemiological data,” Dr. Ammirati agreed. Still, “we do not have any direct evidence in human beings.”

Sex-associated differences in experimental myocarditis have been reported in the journals for at least 70 years, but “the testosterone literature and the estrogen literature have not been evaluated in detail in vaccine-associated myocarditis,” Dr. Cooper said.

Most myocarditis in the laboratory is viral, Dr. Cooper observed, and “the links between testosterone, viruses, and inflammation have been pretty well worked out, I would say, if you’re a mouse. If you’re a human, I think it’s still a bit uncertain.”

Were it to apply in humans, greater testosterone levels might independently promote myocarditis, “and if estrogen is cardioprotective, it would be another mechanism,” Dr. Cooper said. “That would translate to slight male predominance in most kinds of myocarditis.”

In males, compared with females, “the heart can be more vulnerable to events such as arrhythmias or to immune-mediated phenomena. So, probably there is also higher vulnerability to myocarditis in men,” Dr. Ammirati noted.

Male predominance in vaccine-related myocarditis is provocative, so it’s worth considering whether testosterone is part of the mechanism as well as the possibility of estrogen cardioprotection, Dr. Ammirati said. But given limitations of the animal models, “we don’t really have robust data to support any part of that.”

Although myocarditis is in some way immune mediated, “and hormones can modulate the response,” the mechanism has to be more than just sex hormones, he said. “They probably cannot explain the specificity for the heart. It’s not a systemic response, it’s an organ-specific response.”
 

Modulation of immune responses

Details about the immune processes underlying mRNA-vaccine myocarditis, hormone modulated or not, have been elusive. The complication doesn’t resemble serum sickness, nor does it seem to be a reaction to infection by other cardiotropic viruses, such as coxsackie virus B, a cause of viral myocarditis, Dr. Bozkurt said. The latter had been a compelling possibility because such hypersensitivity to smallpox vaccination is well recognized.

“We don’t know the mechanism, that’s the short answer. But there are many hypotheses,” she said. One candidate widely proposed in the literature: autoantibodies driven by molecular mimicry between the SARS-CoV-2 spike protein targeted by the mRNA vaccines and a structurally similar myocardial protein, possibly alpha-myosin, noted Dr. Bozkurt and colleagues in a recent publication.

But elevations in specific “antiheart antibodies” have not been documented in recipients of the two mRNA-based vaccines, said Dr. Cooper. “So, I would say that – although molecular mimicry is a well-established mechanism of, for example, rheumatic carditis after a streptococcal A infection – that has not been demonstrated yet for COVID-19 mRNA vaccination–related myocarditis.”

“We probably won’t know, ever, with a huge level of certainty, the exact mechanisms,” Dr. Cooper added. There is no animal model for vaccine-induced myocarditis, and “We’re still talking very, very small numbers of patients. The vast majority of them recover,” and so don’t generally provide mechanistic clues.  
 

Prospects for younger children

Vaccination against SARS-CoV-2 has now been authorized by the Centers for Disease Control and Prevention for kids as young as 5-11 years, using the Pfizer-BioNTech vaccine. Experience so far suggests the immunization is safe in that age group with negligible risk of myocarditis or other complications. But with prospects of possible authorization in children younger than 5, should myocarditis be a concern for them?

Probably not, if the complication is driven primarily by sex hormones, Dr. Cooper proposed. “One would predict that before puberty you would have a lower – much, much lower – rate of myocarditis in males than you would in the 16- to 19-year-old range, and that it would be roughly equal to females.” Dr. Ammirati and Dr. Bozkurt largely agreed.

It remains to be seen whether the vaccine-related myocarditis risk applies to children younger than 12, “but I doubt it. I think it’s going to be puberty-related,” Dr. Bozkurt said. Still, “I don’t want to hypothesize without data.”

The risk of myocarditis after immunization with mRNA-based vaccines against SARS-CoV-2 raised concerns when it came to light in early 2021. But as report after report showed such cases to be rare and usually mild and self-limited, focus has turned to the “how and why.”  

The mechanism linking the BNT162b2 (Pfizer-BioNTech) and especially mRNA-1273 (Moderna) vaccines to the occurrence of myocarditis is unclear for now, but one potential driver may be tied to a peculiarity that became apparent early: It occurs overwhelmingly in younger males, from 16 to perhaps 40 or 50 years of age. Excess risk has not been consistently seen among women, girls, and older men.

That observation has led to speculation that higher testosterone levels in adolescent boys and young men may somehow promote the adverse vaccine effect, whereas greater levels of estrogen among girls and women in the same age range may be cardioprotective.

Sodium-glucose cotransporter 2 (SGLT2) inhibitors show “remarkable consistency of class benefit” for improving cardiovascular outcomes in high-risk people across age, sex, and race/ethnicity categories.

The findings, from a meta-analysis of 10 major randomized clinical trials, were published online Jan. 5, 2021, in JAMA Network Open by Mukul Bhattarai, MD, a cardiology fellow at Southern Illinois University, Springfield, and colleagues.

“Our meta-analysis evaluated a wide spectrum of efficacy outcomes, further characterizing the primary outcome in different subgroups from several well-designed large clinical trials. It supports that SGLT2 inhibitors have emerged as an effective class of drugs for improving cardiovascular morbidity and mortality, including the prevention of [hospitalization for heart failure] and reducing all-cause mortality in selected patients,” Dr. Bhattarai and colleagues wrote.

The cardiovascular outcomes of SGLT2 inhibitor therapy, they noted, “can be compared across all trials, and it demonstrates remarkable consistency of class benefit, despite the variations in populations enrolled.”

However, they also noted that SGLT inhibitors did not reduce the risk of acute MIn overall, and that most of the trials were short term, with a mean follow-up of just 2.3 years.
 

Ten trials, consistent cardiovascular benefits

Dr. Bhattarai and colleagues searched the literature through Jan. 10, 2021, as well as meeting presentations and other sources. They identified 10 placebo-controlled, randomized clinical trials in which participants had atherosclerotic cardiovascular disease or ASCVD risk factors, diabetes, or heart failure. Among a total of 71,553 high-risk patients, 39,053 received an SGLT2 inhibitor and 32,500 received a placebo.

The primary outcome of cardiovascular death or hospitalization for heart failure occurred in 8.10% randomized to SGLT2 inhibitors, compared with 11.56% in the placebo group, a significant difference with odds ratio 0.67 (P < .001). Both individual outcomes were lower in the SGLT2-inhibitor group, with a number needed to treat of 5.7 (P < .001).

Patients receiving SGLT2 inhibitors also had significantly lower rates of major adverse cardiovascular events, defined as death due to cardiovascular causes, nonfatal MI, or nonfatal stroke. Those events occurred in 9.82% versus 10.22%(OR, 0.90; P = .03).

Hospitalizations and ED visits with heart failure were also reduced with SGLT2 inhibitors (4.37% vs. 6.81%; OR, 0.67; P < .001), as was cardiovascular death (4.65% vs. 5.14%; OR, 0.87; P = .009). The reduction in heart failure is likely caused by a combination of a natriuretic effect and reduced interstitial fluid, along with inhibition of cardiac fibrosis, the authors said.

On the other hand, no reductions were seen in acute MI, evaluated in five of the studies. That event occurred in 4.66% taking SGLT2 inhibitors, compared with 4.70% of the placebo group, a nonsignificant difference with an OR of 0.95 (P = 0.22). This is likely because of the fact that SGLT2 inhibitors don’t have known antianginal properties or vasodilatory effects, they don’t reduce myocardial oxygen consumption, and they don’t prevent cardiac muscle remodeling, they noted.

All-cause mortality was significantly lower with SGLT2 inhibitors, though, at 7.09% versus 7.86% (odds ratio, 0.87; P = .004).
 

Benefits seen across age, sex, and race/ethnicity subgroups

While no differences in benefit were found between men and women when compared with placebo groups, the rates of cardiovascular death or heart failure hospitalizations were slightly higher in men than in women (9.01% [OR, 0.75; P < .001] vs. 5.34% [OR, 0.78; P = .002]).

By age, SGLT2 inhibitors benefited people both those younger than 65 years and those aged 65 years and older, although the primary outcome was slightly lower in the younger group (6.94% [OR, 0.79; P < 0.001] vs. 10.47% [OR, 0.78; P < .001]).

And by race, similar benefits from SGLT2 inhibitors were seen among individuals who were White, compared with those who were Asian, Black, or of other race/ethnicity, with event rates of 8.77% (OR, 0.82; P < .001) and 8.75% (OR, 0.66; P = .06), respectively.

“Owing to the short-term trial durations, future long-term prospective studies and postmarketing surveillance studies are warranted to discover the rate of cardiovascular outcomes,” Dr. Bhattarai and colleagues concluded.

The authors have no disclosures.

Hospitalizations and ED visits with heart failure were also reduced with SGLT2 inhibitors (4.37% vs. 6.81%; OR, 0.67; P < .001), as was cardiovascular death (4.65% vs. 5.14%; OR, 0.87; P = .009). The reduction in heart failure is likely caused by a combination of a natriuretic effect and reduced interstitial fluid, along with inhibition of cardiac fibrosis, the authors said.

On the other hand, no reductions were seen in acute MI, evaluated in five of the studies. That event occurred in 4.66% taking SGLT2 inhibitors, compared with 4.70% of the placebo group, a nonsignificant difference with an OR of 0.95 (P = 0.22). This is likely because of the fact that SGLT2 inhibitors don’t have known antianginal properties or vasodilatory effects, they don’t reduce myocardial oxygen consumption, and they don’t prevent cardiac muscle remodeling, they noted.

All-cause mortality was significantly lower with SGLT2 inhibitors, though, at 7.09% versus 7.86% (odds ratio, 0.87; P = .004).
 

Benefits seen across age, sex, and race/ethnicity subgroups

While no differences in benefit were found between men and women when compared with placebo groups, the rates of cardiovascular death or heart failure hospitalizations were slightly higher in men than in women (9.01% [OR, 0.75; P < .001] vs. 5.34% [OR, 0.78; P = .002]).

By age, SGLT2 inhibitors benefited people both those younger than 65 years and those aged 65 years and older, although the primary outcome was slightly lower in the younger group (6.94% [OR, 0.79; P < 0.001] vs. 10.47% [OR, 0.78; P < .001]).

And by race, similar benefits from SGLT2 inhibitors were seen among individuals who were White, compared with those who were Asian, Black, or of other race/ethnicity, with event rates of 8.77% (OR, 0.82; P < .001) and 8.75% (OR, 0.66; P = .06), respectively.

“Owing to the short-term trial durations, future long-term prospective studies and postmarketing surveillance studies are warranted to discover the rate of cardiovascular outcomes,” Dr. Bhattarai and colleagues concluded.

The antidepressant bupropion failed to improve sexual dysfunction in female cancer survivors, according to new findings published online in the Journal of Clinical Oncology.

Using the Female Sexual Function Index (FSFI) as a measurement tool, investigators found that desire scores were not significantly different for participants who received bupropion versus a placebo over the 9-week study period.

“Sexual health is a complex phenomenon and [our results suggest that] no one intervention is going to solve the broader issue,” lead author Debra Barton, RN, PhD, FAAN, professor in the School of Nursing at the University of Michigan, Ann Arbor, told this news organization.

Sexual dysfunction is common among cancer survivors and experienced across multiple cancer types and stages of disease. Research shows that as many as 70% of female cancer survivors report loss of desire, compared with up to one-third of the general population.

Common sexual concerns among female cancer survivors include low desire, arousal issues, lack of appropriate lubrication, difficulty in achieving orgasm, and pain with penetrative sexual activity. Additionally, these women may experience significant overlap of symptoms, and often encounter multiple sexual issues that are exacerbated by a range of cancer treatments.

“It’s a huge problem,” Maryam B. Lustberg, MD, MPH, from Yale Cancer Center, New Haven, Conn., and colleagues wrote in an accompanying editorial.

Despite the prevalence of sexual dysfunction among cancer survivors, effective treatments remain elusive. Preliminary evidence suggests that bupropion, already approved for seasonal affective disorder, major depressive disorder, and smoking cessation, may also enhance libido.

Dr. Barton and colleagues conducted this phase 2 trial to determine whether bupropion can improve sexual desire in female cancer survivors without undesirable side effects.

In the study, Dr. Barton and colleagues compared two dose levels of extended-release bupropion in a cohort of 230 postmenopausal women diagnosed with breast or gynecologic cancer and low baseline FSFI desire scores (<3.3), who had completed definitive cancer therapy.

Participants were randomized to receive either 150 mg (79 patients) or 300 mg (74 patients) once daily of extended-release bupropion, or placebo (77 patients).

Barton and colleagues then evaluated whether sexual desire significantly improved over the 9-week study period comparing the bupropion arms and the placebo group.

Overall, the authors found no significant differences (mean between-arm change for 150 mg once daily and placebo of 0.02; P = .93; mean between-arm change for 300 mg once daily and placebo of –0.02; P = .92). Mean scores at 9 weeks on the desire subscale were 2.17, 2.27, and 2.30 for 150 mg, 300 mg, and the placebo group, respectively.

In addition, none of the subscales – which included arousal, lubrication, and orgasm – or the total score showed a significant difference between arms at either 5 or 9 weeks.

Bupropion did, however, appear to be well tolerated. No grade 4-5 treatment-related adverse events occurred. In the 150-mg bupropion arm, two patients (2.6%) experienced a grade 3 event (insomnia and headache) and one patient in the 300-mg bupropion arm (1.4%) and placebo arm (1.3%) experienced a grade 3 event related to treatment (hypertension and headache, respectively).

In the accompanying editorial, Dr. Lustberg and colleagues “applaud the authors for conducting a study in this population of cancer survivors,” noting that “evidenced-based approaches have not been extensively studied.”

Dr. Lustberg and colleagues also commented that other randomized controlled clinical trials evaluating sexual desire disorder assessed outcomes using additional metrics, such as the Female Sexual Distress Scale–Revised questionnaire, which measures distress related to sexual dysfunction and low desire, in particular.

“The use of specific validated instruments for libido in place of the FSFI might have helped determine the effect of the study intervention in this reported trial,” they wrote.

Overall, according to Dr. Lustberg and colleagues, the negative results of this study indicate that a multidisciplinary clinical approach may be needed.

“As much as we would like to have one intervention that addresses this prominent issue, the evidence strongly suggests that cancer-related sexual problems may need an integrative biopsychosocial model that intervenes on biologic, psychologic, interpersonal, and social-cultural factors, not just on one factor, such as libido,” they wrote. “Such work may require access to multidisciplinary care with specialists in women’s health, pelvic floor rehabilitation, and psychosocial oncology.”

Dr. Barton said she has been developing a multicomponent approach to addressing sexual health in female cancer survivors.

However, she noted, “there is still much we do not fully understand about the broader impact of the degree of hormone deprivation in the population of female cancer survivors. A better understanding would provide clearer targets for interventions.” 

The study was supported by the National Cancer Institute and Breast Cancer Research Foundation. Dr. Barton has disclosed research funding from Merck. Dr. Lustberg reported receiving honoraria from Novartis and Biotheranostics; consulting or advising with PledPharma, Disarm Therapeutics, Pfizer; and other relationships with Cynosure/Hologic.

Statins may be safe when used during pregnancy, with no increase in risk for fetal anomalies, although there may be a higher risk for low birth weight and preterm labor, results of a large study from Taiwan suggest.

The Food and Drug Administration relaxed its warning on statins in July 2021, removing the drug’s blanket contraindication in all pregnant women.

Removal of the broadly worded contraindication should “enable health care professionals and patients to make individual decisions about benefit and risk, especially for those at very high risk of heart attack or stroke,” the FDA said in their announcement.

“Our findings suggested that statins may be used during pregnancy with no increase in the rate of congenital anomalies,” wrote Jui-Chun Chang, MD, from Taichung Veterans General Hospital, Taiwan, and colleagues in the new study, published online Dec. 30, 2021, in JAMA Network Open.

“For pregnant women at low risk, statins should be used carefully after assessing the risks of low birth weight and preterm birth,” they said. “For women with dyslipidemia or high-risk cardiovascular disease, as well as those who use statins before conception, statins may be continuously used with no increased risks of neonatal adverse effects.”

The study included more than 1.4 million pregnant women aged 18 years and older who gave birth to their first child between 2004 and 2014.

A total of 469 women (mean age, 32.6 years; mean gestational age, 38.4 weeks) who used statins during pregnancy were compared with 4,690 matched controls who had no statin exposure during pregnancy.

After controlling for maternal comorbidities and age, women who used statins during pregnancy were more apt to have low-birth-weight babies weighing less than 2,500 g (risk ratio, 1.51; 95% confidence interval, 1.05-2.16) and to deliver preterm (RR, 1.99; 95% CI, 1.46-2.71).

The statin-exposed babies were also more likely to have a lower 1-minute Apgar score (RR, 1.83; 95% CI, 1.04-3.20). Importantly, however, there was no increase in risk for fetal anomalies in the statin-exposed infants, the researchers said.

In addition, for women who used statins for more than 3 months prior to pregnancy, maintaining statin use during pregnancy did not increase the risk for adverse neonatal outcomes, including congenital anomalies, low birth weight, preterm birth, very low birth weight, low Apgar scores, and fetal distress.

The researchers called for further studies to confirm their observations.

Funding for the study was provided by Taichung Veterans General Hospital. The authors have disclosed no relevant financial relationships.

Adjunctive treatment with the novel oral medication REL-1017 (esmethadone) is effective in adults with major depressive disorder (MDD) who have failed other antidepressants, new research suggests.
 

REL-1017, from Relmada Therapeutics, is a novel N-methyl-D-aspartate receptor (NMDAR) channel blocker that preferentially targets hyperactive channels while maintaining physiologic glutamatergic neurotransmission.

Jupiterimages/ThinkStock

Results from a phase 2a study showed rapid “therapeutic efficacy,” with a statistical difference by day 4, and the improvement was “robust,” with an effect size of 0.7 to 1. The positive outcome was also sustained for at least 1 week after treatment discontinuation, coinvestigator Paolo L. Manfredi, MD, chief scientific officer, Relmada Therapeutics, noted.

“Considering that the available traditional antidepressants have an average effect size around 0.3, this novel, potential rapid-acting antidepressant … holds great promise for millions of patients suffering from depression,” Dr. Manfredi told this news organization.

These results were obtained with a “very-well-tolerated once-daily oral NMDAR antagonist, without the dissociative effects seen with ketamine,” he added.

The findings were published online in the American Journal of Psychiatry.

‘Clear need’ for better therapies

It is estimated that more than half of patients with MDD fail to respond adequately following their first standard antidepressant treatment. In addition, responses are often delayed by 4-8 weeks after starting an antidepressant.

Therefore, there is a “clear need” to develop drugs for MDD that act quickly and with improved efficacy, the investigators note.

The phase 2a study of REL-1017 enrolled 62 adult patients (45% women) aged 18-65 years with moderate to severe MDD and no significant psychiatric comorbidity. All had failed to benefit from one to three standard antidepressant treatments in their current major depressive episode.

The researchers evaluated two doses of REL-1017 (25 mg and 50 mg once daily) vs. placebo given as adjunctive treatment. The assigned treatment lasted 7 days.

The primary study objectives were safety and tolerability. Results showed no serious adverse events (AEs), and no patients experienced treatment-emergent AEs that led to the stopping of treatment.

In addition, patients receiving the active drug experienced mild or moderate transient AEs comparable to placebo, with no opioid, dissociative, or psychotomimetic symptoms, or withdrawal effects when treatment ended.

The most common AEs reported were headache, constipation, nausea, and sleepiness.

Significant efficacy

The primary efficacy endpoint was the Montgomery–Åsberg Depression Scale (MADRS) score.

Mean MADRS score at baseline was 33.8 in the placebo group vs. 32.9 in the REL-1017 25-mg group and 35.2 in the REL-1017 50-mg group.

MADRS scores showed improvement on day 4 of treatment in both REL-1017 groups, and the improvement continued through day 7 (last dose) and day 14 (7 days after the last dose), with P ≤ .0308 and effect sizes ranging from 0.7 to 1.0.

Mean change from baseline in MADRS scores showed more improvement at the end of the dosing period for both dosing groups (–16.8 with 25 mg and –16.6 with 50 mg) vs. –8.8 with placebo.

Results of the other efficacy endpoints of Symptoms of Depression Questionnaire (SDQ) score and Clinical Global Impressions severity scale (CGI-S) and improvement scale (CGI-I) scores were similar to that of the MADRS.

Remission rates (defined as a MADRS score ≤10) on day 14, the last day of efficacy assessment, were 5% with placebo vs. 31% (P = .035) with REL-1017 25 mg and 39% (P = .01) with REL-1017 50 mg.

The number needed to treat to achieve remission on day 14 was four with the 25-mg dose and three with the 50-mg dose.

Phase 3 trials to confirm the efficacy and safety of REL-1017 are in progress, with topline results expected later this year, the investigators report.

The study was funded by Relmada Therapeutics. Dr. Manfredi has received personal fees from and/or held stock ownership in Relmada. Disclosures for the other investigators are fully listed in the original article.

Remission rates (defined as a MADRS score ≤10) on day 14, the last day of efficacy assessment, were 5% with placebo vs. 31% (P = .035) with REL-1017 25 mg and 39% (P = .01) with REL-1017 50 mg.

The number needed to treat to achieve remission on day 14 was four with the 25-mg dose and three with the 50-mg dose.

Phase 3 trials to confirm the efficacy and safety of REL-1017 are in progress, with topline results expected later this year, the investigators report.

The study was funded by Relmada Therapeutics. Dr. Manfredi has received personal fees from and/or held stock ownership in Relmada. Disclosures for the other investigators are fully listed in the original article.

Adjunctive treatment with the novel oral medication REL-1017 (esmethadone) is effective in adults with major depressive disorder (MDD) who have failed other antidepressants, new research suggests.
 

REL-1017, from Relmada Therapeutics, is a novel N-methyl-D-aspartate receptor (NMDAR) channel blocker that preferentially targets hyperactive channels while maintaining physiologic glutamatergic neurotransmission.

Results from a phase 2a study showed rapid “therapeutic efficacy,” with a statistical difference by day 4, and the improvement was “robust,” with an effect size of 0.7 to 1. The positive outcome was also sustained for at least 1 week after treatment discontinuation, coinvestigator Paolo L. Manfredi, MD, chief scientific officer, Relmada Therapeutics, noted.

“Considering that the available traditional antidepressants have an average effect size around 0.3, this novel, potential rapid-acting antidepressant … holds great promise for millions of patients suffering from depression,” Dr. Manfredi told this news organization.

These results were obtained with a “very-well-tolerated once-daily oral NMDAR antagonist, without the dissociative effects seen with ketamine,” he added.

The findings were published online in the American Journal of Psychiatry.

‘Clear need’ for better therapies

It is estimated that more than half of patients with MDD fail to respond adequately following their first standard antidepressant treatment. In addition, responses are often delayed by 4-8 weeks after starting an antidepressant.

Therefore, there is a “clear need” to develop drugs for MDD that act quickly and with improved efficacy, the investigators note.

The phase 2a study of REL-1017 enrolled 62 adult patients (45% women) aged 18-65 years with moderate to severe MDD and no significant psychiatric comorbidity. All had failed to benefit from one to three standard antidepressant treatments in their current major depressive episode.

The researchers evaluated two doses of REL-1017 (25 mg and 50 mg once daily) vs. placebo given as adjunctive treatment. The assigned treatment lasted 7 days.

The primary study objectives were safety and tolerability. Results showed no serious adverse events (AEs), and no patients experienced treatment-emergent AEs that led to the stopping of treatment.

In addition, patients receiving the active drug experienced mild or moderate transient AEs comparable to placebo, with no opioid, dissociative, or psychotomimetic symptoms, or withdrawal effects when treatment ended.

The most common AEs reported were headache, constipation, nausea, and sleepiness.

Significant efficacy

The primary efficacy endpoint was the Montgomery–Åsberg Depression Scale (MADRS) score.

Mean MADRS score at baseline was 33.8 in the placebo group vs. 32.9 in the REL-1017 25-mg group and 35.2 in the REL-1017 50-mg group.

MADRS scores showed improvement on day 4 of treatment in both REL-1017 groups, and the improvement continued through day 7 (last dose) and day 14 (7 days after the last dose), with P ≤ .0308 and effect sizes ranging from 0.7 to 1.0.

Mean change from baseline in MADRS scores showed more improvement at the end of the dosing period for both dosing groups (–16.8 with 25 mg and –16.6 with 50 mg) vs. –8.8 with placebo.

Results of the other efficacy endpoints of Symptoms of Depression Questionnaire (SDQ) score and Clinical Global Impressions severity scale (CGI-S) and improvement scale (CGI-I) scores were similar to that of the MADRS.

Remission rates (defined as a MADRS score ≤10) on day 14, the last day of efficacy assessment, were 5% with placebo vs. 31% (P = .035) with REL-1017 25 mg and 39% (P = .01) with REL-1017 50 mg.

A new analysis of cardiovascular adverse drug reactions for non–small cell lung cancer (NCSLC)–targeted therapies finds that ALK and ROS1 inhibitors are associated with higher odds of conduction disease and QT prolongation than BRAF and EGFR inhibitors.

The findings are especially important because cardiovascular disease is known to be associated with NSCLC. Even before the start of therapy, 14%-22% of patients with stage I-IV NSCLC have heart failure and 26%-31% of patients have arrhythmias. No other study to date has described cardiovascular effects to this extent as a result of treatment.

The findings were published in the Journal of Thoracic Oncology.

Led by Joel W. Neal, MD, PhD, a medical oncologist at Stanford (Calif.) Health Care, researchers evaluated the association between NSCLC-targeted agents with arrhythmia and heart failure. Their findings are based on analysis of data from the World Health Organization pharmacovigilance database VigiBase. They found that of 98,765 adverse reactions, 61,383 occurred in patients treated with EGFR inhibitors, 15,540 were associated with ALK inhibitors, and 21,842 were associated with BRAF and MEK inhibitors. Arrhythmias occurred in 1,783 patients and 1,146 patients had heart failure.
 

The specifics

Strong associations with conduction disease and QT prolongation were found for ALK and ROS1 inhibitors, especially crizotinib. Of QT prolongation cases, 38.5% of patients on ceritinib and 18.4% of patients on crizotinib also had conduction disease and 7.9% of alectinib-associated conduction disease cases also had prolongation.

BRAF and MEK inhibitors had stronger associations with heart failure, while osimertinib, a third-generation EGFR tyrosine kinase inhibitor, was strongly associated with QT prolongation, supraventricular tachycardia, and heart failure.

ALK inhibitors were found to be 13 times more likely to lead to conduction disease and five times more likely to lead to lead to long QT syndrome as compared to all NSCLC-targeted therapies together. ALK inhibitor crizotinib had significantly higher odds of conduction disease, compared with all other targeted therapies, but of all ALK inhibitors, ceritinib and lorlatinib had the lowest odds of conduction disease. Crizotinib was 1.9 times more likely to lead to QT prolongation than other ALK inhibitors.

The EGFR inhibitor osimertinib was associated with 49 times more like to lead to long QT syndrome than other EGFR inhibitors and 6 times more likely as compared with all other targeted therapies. The EGFR inhibitor gefitinib was twice as likely than other EGFR inhibitors to lead to conduction disease. The third-generation EGFR inhibitor osimertinib had approximately two times higher odds of supraventricular tachycardia than other EGFR inhibitors.

Osimertinib was associated with 6.8 times higher chances of heart failure, compared with other EGFR inhibitors, and 3.6 times more than other targeted therapies. Dabrafenib and trametinib were associated with two to three times higher odds of heart failure as compared with other targeted therapies.

“There is a need for an understanding of the mechanisms underlying these toxicities and for additional studies to establish standardized guidelines for monitoring, particularly for osimertinib, crizotinib, and alectinib,” the authors wrote

The authors disclosed a number of paid advisory roles with various pharmaceutical companies.

The Food and Drug Administration has approved inclisiran (Leqvio) as an adjunct to statins for further reduction of LDL cholesterol levels, the drug’s developer, Novartis, announced on Dec. 22, 2021.

The first-in-class small interfering RNA (siRNA) agent is also novel among peer drug therapies for its administration by injection initially, at 3 months, and thereafter twice per year.

Inclisiran is indicated for use atop maximally tolerated statins in adults with clinical cardiovascular disease or in patients with heterozygous familial hypercholesterolemia, the company reported.

Such patients who received inclisiran, compared with placebo, in the ORION-9, ORION-10, and ORION-11 randomized trials on which the FDA approval was based showed LDL-C reductions exceeding 50% over 1-2 years.

The drug works by “silencing” RNA involved in synthesis of PCSK9, which has a role in controlling the number of LDL cholesterol cell-surface receptors, a unique mechanism of action among available treatments for dyslipidemia.

Novartis, the company said, “has obtained global rights to develop, manufacture, and commercialize Leqvio under a license and collaboration agreement with Alnylam Pharmaceuticals.”

The drumbeat of U.S. recalls continues for various lots of extended-release metformin because of contamination with unacceptably high levels of a nitrosamine that pose a cancer risk.

On Dec. 28, 2021, Viona Pharmaceuticals voluntarily recalled 33 lots of metformin hydrochloride extended-release tablets, USP 750 mg to the retail level, as a precautionary measure, because of possible contamination with N-nitrosodimethylamine (NDMA).

Metformin is used as an adjunct to diet and exercise to improve blood glucose control in adults with type 2 diabetes mellitus. Patients who have received impacted lots of metformin are advised to continue taking their medication and contact their physician for advice regarding an alternative treatment

The product can be identified as white to off-white, capsule shaped, uncoated tablets, debossed with “Z,” “C” on one side and “20” on the other side, and come in bottles of 100 tablets, which have been distributed nationwide. The 33 batch numbers are listed in a company statement.

The affected product was manufactured by Cadila Healthcare, Ahmedabad, India, for U.S. distribution by Viona.

In its statement, Viona said: “NDMA is classified as a probable human carcinogen (a substance that could cause cancer) based on results from laboratory tests. NDMA is a known environmental contaminant and found in water and foods, including meats, dairy products, and vegetables.”

This recall is being conducted “with the knowledge of the U.S. Food and Drug Administration,” it added.

Consumers with questions regarding this recall can contact the recall processor Eversana Life Science Services by phone at 1-888-304-5022, option 1; Monday-Friday, 8:00 a.m.–7:00 p.m. CT. Customers with medical-related questions who wish to report an adverse event or quality issues about the products being recalled should contact Viona Pharmaceuticals by phone at 888-304-5011, Monday-Friday, 8:30 p.m.–5:30 p.m., EST.
 

Latest in a long line of metformin recalls

This is the second time in 2021 that Viona has voluntarily recalled extended-release metformin tablets, 750 mg, because of potential contamination with NDMA. It recalled two lots in June, as reported by this news organization.

And in January 2021, Nostrum Laboratories recalled another lot of metformin extended-release 750-mg tablets, following on from a prior recall in November 2020.

These recalls follows 258 distinct U.S. lot recalls tracked by the FDA during the past 2 years because of unacceptably high NDMA levels in lots of metformin hydrochloride extended-release tablets.

The FDA has issued several statements about NDMA contamination of metformin formulations over the past 2 years, including a review of the methods used to detect NDMA and a summary of the information the agency had collected on excessive levels of NDMA in metformin.

According to the FDA’s 2020 summary, the agency has not yet determined how or why high levels of NDMA turn up so often in multiple batches of metformin hydrochloride extended-release tablets. However, published research attributed the contamination to certain methods of manufacturing metformin tablets.
