Deerfielders Weigh in on a Safe Return to Work Policy Amid Covid-19 Crisis

Antibody testing provides a data-driven path to getting people back into the economy

The availability of point of care antibody testing—also known as serological testing—may provide a feasible roadmap for getting people back to work safely following the COVID-19 crisis, according to an editorial published in the journal Contemporary Clinical Trials Communications.

“You can’t stop the economy forever,” asserted Governor Cuomo in a recent news conference, according to STAT. “So we have to start to think about, does everyone stay out of work? Should young people go back to work sooner? Can we test for those who had the virus, resolved, and are now immune, and can they start to go back to work?”

Regardless of whether they already have immunity to the virus, millions of Americans may try to return to work, potentially undoing all the benefits of the shutdown, suggests the editorial. 

Antibody testing, the authors argue, could clarify a person’s status quickly in real-time and reveal whether they have been exposed to COVID-19. Accordingly, a person who mounts an IgG positive response (suggesting the presence of immunoglobulin G antibodies) would most likely now be immune to the virus and an IgM positive result would point to the process of developing immunity in someone who more recently became infected.

“Unlike the PCR tests (a measure of virus material), the immediate results and unconstrained supply of antibody tests could fundamentally change the way we manage this epidemic,” says Robert Jackson, MD, a co-author of the paper. “And from an economic perspective, it could lead to a tractable path for people to return to work. Collecting the data and tracking individuals longitudinally, in order to confirm the hypothesis, will be necessary.”

And barring any HIPAA concerns, the authors propose that persons with positive antibody tests during periods of social distancing could get a bracelet, which indicates that they are immune-protected and can return to work. Those without a bracelet would still be asked to practice social-distancing and not yet resume their normal activities. But this approach could potentially get at least some portion of the economy back running again, suggests the authors.

According to the authors, the antibody tests are cheap, easy to administer, and could be made available at every hospital.

“Broad testing is in society’s best interest,” says Alex Karnal, a co-author of the editorial. “Until we make serological tests available in a robust way, it’s as if we are flying a plane without navigation.”

Authors of the editorial, titled, “Let’s Get Americans Back to Work Again,” are: Alex Karnal, Partner and Managing Director; Robert Jackson, MD, Partner and Chief Science Officer; and Joe Pearlberg, MD, PhD, Vice President of Scientific Affairs, all at Deerfield; and Amitabh Chandra, PhD, McCance Family Professor at Harvard Business School and Weiner Professor at the Harvard Kennedy School.

Is it time for the weighted log-rank test to play a more important role in confirmatory trials?

The log-rank test is frequently used to detect a potential treatment effect in randomized clinical trials with time-to-event endpoints. It is asymptotically the most powerful test under the proportional hazards setting, but it has been shown to markedly lose power when the proportional hazards assumption is violated.

Press releases for Phase 2 clinical trial topline results: Have the objective pre-specified efficacy results been disclosed?

Phase 2 clinical trials are of vital importance in the drug development process as they usually gather preliminary evidence of efficacy of potentially new therapies and support the go/no-go decision for Phase 3 pivotal trials. Topline results of Phase 2 trials are typically first disclosed through press releases so that key stakeholders (patients and their advocacy groups, physicians, clinical trials practitioners, investors, etc.) can have timely access to a high level summary of the important findings. The sponsors of the trials often will save more detailed findings for future medical conference presentations and/or peer-reviewed journal publications, and as a result there may be an extended period of time where only the topline results are available on which stakeholders can rely. It is therefore critical for trial sponsors to release objective findings and avoid selective disclosure of favorable results.
