With hundreds of clinical trials for potential coronavirus therapies in the works concerns have mounted about the emergence of conflicting data, useless results, and wasted efforts from multiple overlapping efforts.
With hundreds of clinical trials for potential coronavirus therapies in the works-and even more in development-concerns have mounted about the emergence of conflicting data, useless results, and wasted efforts from multiple overlapping efforts. In response, the National Institutes of Health (NIH) announced a broad public-private partnership (PPP) to collaborate on prioritizing and coordinating research on COVID-19 drug and vaccine candidates. The Accelerating COVID-19 Therapeutic Interventions and Vaccines (ACTIV) initiative has support from a number of federal agencies, and some 16 pharma and biotech companies are participating through the Foundation for the National Institutes of Health (FNIH).
Widespread research activity is available from these and other organizations:
|The University of Oxford Centre for Evidence-Based Medicines lists more than 1000 clinical trials.||http://covid19.trialstracker.net/index.html|
|Bill & Melinda Gates Foundation with Cytel identifies more than 600 trials in the US and other regions.||https://covid19-trials.com/|

|BioCentury tracks vaccines and therapeutics in its COVID-19 Resource Center.||https://www.biocentury.com/clinical-vaccines-and-therapies|
NIH Director Francis Collins emphasizes the importance of bringing “unassailable objectivity” to swiftly identify the most promising compounds from multiple stakeholders. Those priority therapies should gain fast and efficient regulatory oversight and vetting, moreover, through the involvement of FDA and the European Medicines Agency (EMA) in the partnership.
This initiative builds on earlier efforts, such as the COVID-19 Therapeutics Accelerator launched in March by the Bill & Melinda Gates Foundation to drive collaboration among drug makers, regulators, and non-governmental organizations. In addition, more than a dozen biopharma companies formed the COVID R&D consortium to share public information on research efforts, while several international organizations are coordinating clinical trials and developing master protocols.
The new NIH-based partnership appears poised to advance collaborative research more extensively, with industry and government partners providing infrastructure, subject matter expertise, and funding to identify top priority candidates for advanced testing. FNIH will manage an ACTIV steering committee to develop an inventory of potential candidates, launch master protocols with a single control arm, and set criteria for ranking potential candidates for first wave and subsequent evaluation. Another sub-group will set standards for preclinical evaluation methods through a central repository to assess models, extend high-throughput screening facilities, and compare approaches for identifying informative assays. And a third group will tap NIH’s extensive clinical trial network infrastructure to build capacity for expediting trials and to study different populations and disease stages.
To advance vaccine development, another ACTIV group will form a collaborative framework to map epitopes and develop assays, establish protocols for sampling and immunological analyses, collect clinical data on immunological responses and endpoints, and engage with regulators on surrogate endpoints for clinical evaluation.
ACTIV’s initial goal is to select six to eight compounds for clinical trials that assess different mechanisms of action, Collins explained in a recent webinar sponsored by the Duke Margolis Center for Health Policy. He noted that the working groups met in early April to start the process of identifying the highest potential therapies, particularly those where manufacturing scale-up won’t be a major roadblock. The candidates will include anti-virals with well-established mechanisms of action, immune therapies, and immune suppressants for patients with advanced lung disease.
Establishing “really organized clinical trial capacity” is critical to be able to slot promising compounds into networks utilizing master protocols, Collins emphasized. Even if current studies of existing therapies such as remdesivir show benefit, he predicts a strong need for combination therapies going forward.
FDA is deeply engaged in all these working groups to ensure that the group’s clinical studies will meet regulatory standards. And it’s all moving “at rocket pace,” Collins observed, with the goal of identifying two to three promising therapies by July or August for further testing in the fall. A main benefit of this initiative, he noted, is that “all stakeholders are together around the table.” Biopharma companies are “not just pushing their own candidates,” he noted, and are offering clinical trial capacity “to get this done.”
