Candidate: TJM2 (TJ003234)

Category: ANTIBODY

Type: Neutralizing antibody against human granulocyte-macrophage colony stimulating factor (GM-CSF)

Status: I-Mab said April 3 that the FDA cleared its IND to initiate clinical study of TJM2 as a treatment for cytokine release syndrome associated with severe illness caused by COVID-19. I-Mab also obtained central institutional review board (IRB) approval from the Western Institutional Review Board on the same day. The planned trial is a multi-center, randomized, double-blind, placebo-controlled, three-arm study designed to assess the safety, tolerability and efficacy of TJM2 in reducing the severity of complications as well as levels of multiple cytokines in patients with severe COVID-19.

I-Mab added that it submitted an IND application to South Korea’s Ministry of Food and Drug Safety for a similar study in severe COVID-19 patients in South Korea.


COVID-19: 200 Candidates and Counting

To navigate through the >200 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.

GEN has also tagged the most common treatment types:

● ANTIVIRAL
● VAX
● ANTIBODY
● RNA
