Type: Oral SARS-CoV2-3CL protease inhibitor
2020 Status: Pfizer on March 13 restated earlier plans to develop its own antivirals against COVID-19 as well as collaborate with BioNTech on an mRNA vaccine to prevent the disease. The pharma giant also articulated five principles it said would govern its drug and vaccine development activity: Sharing tools and insights; creating “a SWAT team” of experts focused solely on fighting the pandemic; applying its drug development expertise; offering any excess manufacturing capacity to support other drug and vaccine developers; and building a “cross-industry rapid response team of scientists, clinicians and technicians” to improve response to future epidemics.
Earlier in March, Pfizer said it completed a preliminary assessment of antiviral compounds that were previously in development and that inhibited the replication of coronaviruses similar to the one causing COVID-19 in cultured cells. Pfizer said it was engaging with a third party to screen these compounds under an accelerated timeline and expected to have results back by the end of March.
“Toxicology studies would then need to be completed prior to any clinical development, but if successful, Pfizer hopes to be in the clinic by no later than the end of 2020,” the company added.
COVID-19: 300 Candidates and Counting
To navigate through the >300 potential therapeutic and vaccine options for COVID-19, GEN has grouped the candidates into four broad categories based on their developmental and (where applicable) clinical progress:
● FRONT RUNNER – the most promising therapeutics/vaccines based on clinical progress, favorable data or both.
● DEFINITELY MAYBE – earlier phases with promising partners, or more advanced candidates in development that have generated uneven data
● KEEPING AN EYE ON… – interesting technology, attracting notable partners, or both, but preliminary data.
● TOO SOON TO TELL – longshots pending additional experimental and/or clinical data.
