Biopharmaceutical companies and federal agencies alike are continuing to work overtime to develop safe and effective COVID-19 preventives for patients around the world in the coming months.
As the Trump administration revs up its Operation Warp Speed initiative to accelerate access to COVID-19 vaccines and therapeutics, biopharmaceutical companies and federal agencies continue to work overtime to test and develop safe and effective preventives for patients around the world. Research is underway on more than 175 vaccine candidates across a wide range of technologies, as sponsors and scientists look to have, “multiple shots on goal,” along with, “multiple goals to shoot at,” in the race to identify effective products in the coming months.
This proliferation of vaccine research programs, however, highlights the importance of carrying out clinical trials that utilize similar protocols and endpoints able to produce comparable results. Peter Marks, director of the Center for Biologics Evaluation and Research (CBER), acknowledges the need for regulators to move quickly, while also being sure to “check all the boxes” so that research yields clear evidence that a vaccine is safe and effective. FDA is “willing to take certain calculated risks to get into phase I” and to accept novel trial designs, particularly with vaccine platforms that have been used before, Marks noted in a webinar sponsored by the Duke Margolis Center for Health Policy May 13, 2020. But he also recognizes that FDA has to convince people that we’re, “not taking shortcuts here.”
Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases (NIAID), similarly emphasizes the need to assess different candidates in ways that complement each other in order to get definitive answers about whether a vaccine works or not. Without complete clinical trials, researchers may get a signal that “strongly indicates” a response, but “doesn’t nail it down,” Fauci warned.
These experts further advised sponsors to utilize clinical research networks in locations with high incidences of COVID-19 cases to be able to assess efficacy efficiently. Sponsors need to “go where the cases are-not the traditional sites,” said Marks, acknowledging unhappily that widespread infection rates should facilitate getting data quickly. At the same time, sponsors should “space out” trials to different locations to avoid bias, while also utilizing endpoints that are similar enough to be able to compare results from different studies.
Despite anticipated pressure to permit expanded or emergency access to any promising vaccine, Marks doesn’t envision authorizing such use during phase III trials for fear of undermining efforts to obtain definitive data. Some early use may be approved for health professionals and at-risk patients during the few months between when a clinical trial ends and the sponsor completes the analysis needed to support a biologics licensing application, so long as such access doesn’t short-circuit clinical assessment.
The tight timeframes for developing and then distributing any successful vaccines means that companies cannot wait for final clinical test results to begin preparing large-scale manufacturing operations and to address supply chain issues critical for delivering products globally. Consequently, instead of spending several years testing vaccine candidates and then ramping up production based on successful findings, industry and government agencies “have to proceed at risk,” Fauci acknowledges, and invest in operations before they have a product that would be used.
While the medical community sees many patients recovering from COVID by mounting a strong immune response to the virus, Marks acknowledges that scientists still have only a limited understanding of what will constitute long-term, definitive protection. He admits to having “great concerns” about a second pandemic wave this fall and winter and will be very pleased to have a vaccine with strong efficacy data by then. A preventive that could get to herd immunity “would be really nice,” he commented. But regulators and researchers expect to move forward with any vaccine that indicates it can help get the pandemic under control, even without clear assurances for long-term success.
Behind the Buzz: Why Clinical Research Leaders Flock to SCOPE Summit
February 7th 2025In this episode, we meet with Micah Lieberman, Executive Conference Director for SCOPE Summit (Summit for Clinical Ops Executives) at Cambridge Innovation Institute. We will dive deep into the critical role of collaboration within the clinical research ecosystem. How do we bring together diverse stakeholders—sponsors, CROs, clinical trial tech innovators, suppliers, patients, sites, advocacy organizations, investors, and non-profits—to share best practices in trial design, program planning, innovation, and clinical operations? We’ll explore why it’s vital for thought leaders to step beyond their own organizations and learn from others, exchanging ideas that drive advancements in clinical research. Additionally, we’ll discuss the pivotal role of scientific conferences like SCOPE Summit in fostering these essential connections and collaborations, helping shape the future of clinical trials. Join us as we uncover how collective wisdom and cross-industry partnerships are transforming the landscape of clinical research.
