Genus Medical Technologies v FDA -Lack of Judicial Deference to FDA Expertise

A recent commentary (PJ Zettler et al. NEJM 2021; 385: 2409-2411. A Divisive Ruling on Devices — Genus Medical Technologies v. FDA) highlights another challenge facing the FDA’s role in regulating devices, especially as the definition of devices and medications becomes more murky.

Key points/excerpts:

  • In April 2021, however, the U.S. Court of Appeals for the District of Columbia decided, in Genus Medical Technologies v. FDA, that products meeting the FDCA’s definition of a device “must be regulated as devices”…The Genus case concerned a challenge to the discretion of the FDA to classify Genus Medical Technologies’ Vanilla SilQ line of diagnostic barium sulfate contrast agents as drugs rather than as devices…FDCA’s drug and device definitions overlap.
  • Ultimately, the D.C. Circuit Court held that products meeting both definitions must be regulated as devices because the FDCA’s “text unambiguously forecloses the FDA’s interpretation.” The court did not give the FDA so-called Chevron deference, a doctrine under which courts defer to an agency’s reasonable interpretation of a statute that it implements, if the statute is ambiguous.
  • Because technological innovation often outpaces legal change, we believe it could serve both public health and industry for the FDA to retain some discretion regarding the most appropriate regulatory pathways for anticipated and as-yet-unforeseen device classes… overly restricting the FDA’s flexibility to use its expertise could endanger important public health priorities, especially when there are compelling reasons why Congress permitted flexibility.
  • The Genus decision comes at the end of a decade of growing challenges to the FDA’s authority to regulate. From court decisions in the early 2010s that were sympathetic to arguments that FDA policies regarding off-label drug promotion violate the Constitution’s First Amendment, [and] to the political (and legislative) success of right-to-try laws

My take: This commentary shows the difficulties the FDA faces as the judiciary curtails its discretion. While the legislative branch could codify FDA authority, this is unlikely. As such, this will limit FDA oversight in some new medical products. When problems arise, it is likely that the FDA (not the courts) will be blamed despite the fact that their ability to regulate has been undermined.

Omicron Data

This data from NY Times shows that deaths due to COVID-19 are following a familiar pattern and spiking about 3 weeks after a spike in cases; this time the spike is being driven by omicron cases. However, this wave may in fact have lower severity per case; with this current wave, the number of reported cases is probably undercounted by a greater degree than in previous spikes due to widespread availability of home testing and the likelihood of more asymptomatic cases. Thus, it could be that the death rate per case would/will be significantly lower if/when all cases are accounted for.

My take: Cardiac complications related to COVID-19 appear to be much more likely than adverse cardiac events due to vaccination.

Vaccination Reduces Risk of COVID-19 Associated MIS-C & New Quarantine Guidelines

M Levy et al. JAMA. Published online December 20, 2021. doi:10.1001/jama.2021.23262. Open Access: Multisystem Inflammatory Syndrome in Children by COVID-19 Vaccination Status of Adolescents in France

Key findings:

  • From September 1, 2021, to October 31, 2021, a total of 107 children with MIS-C were hospitalized in France…33 (31%) were adolescents eligible for vaccination
  • Among those with MIS-C, 0 had been fully vaccinated, 7 had received 1 dose with a median (IQR) time between vaccine injection and MIS-C onset of 25 (17-37) days, and 26 had not been vaccinated. The HR for MIS-C was 0.09 (95% CI, 0.04-0.21; P < .001) after the first vaccine dose compared with unvaccinated adolescent. Because there were no MIS-C cases in those who were vaccinated, an HR cannot be calculated in this group.
  • The study had limitations, including the low number of patients, use of national data to calculate HR without considering regional variations, and inability to control for individual risks of MIS-C, such as sex, race and ethnicity, and comorbidities

My take: This study indicates that COCID-19 vaccination likely results in a marked decrease in the risk of MISC-C. This finding provides an additional reason favoring vaccination in adolescents in terms of risk-benefit calculation for immunization.

12/27/21: CDC Updates and Shortens Recommended Isolation and Quarantine Period for General Population

Latest CDC Recommendations: Work Restrictions for Healthcare Workers with COVID-19 and Exposures

12/23/21: CDC Releases Emergency Guidance for Healthcare Facilities to Prepare for Potential Omicron Surge

  • Healthcare workers with COVID-19 who are asymptomatic can return to work after 7 days with a negative test, and that isolation time can be cut further if there are staffing shortages.
  • Healthcare workers who have received all recommended COVID-19 vaccine doses, including a booster, do not need to quarantine at home following high-risk exposures.

What We Know Right Now About Omicron and About Boosters

This article shows that the booster shot lowers the risk of death by 90% compared to those who did not receive the booster shot in those 50 years of age or older. R Arbel et al. NEJM 2021; DOI: 10.1056/NEJMoa2115624. Open Access: BNT162b2 Vaccine Booster and Mortality Due to Covid-19

Key Findings:

  • A total of 843,208 participants (50 years and older) met the eligibility criteria, of whom 758,118 (90%) received the booster during the 54-day study period. Death due to Covid-19 occurred in 65 participants in the booster group (0.16 per 100,000 persons per day) and in 137 participants in the nonbooster group (2.98 per 100,000 persons per day). The adjusted hazard ratio for death due to Covid-19 in the booster group, as compared with the nonbooster group, was 0.10 (95% confidence interval, 0.07 to 0.14; P<0.001).
