    About Proxalutamide

    Proxalutamide is a nonsteroidal antiandrogen — specifically, a selective high-affinity silent antagonist of the androgen receptor — that is under development for the potential treatment of COVID-19, prostate cancer, and breast cancer. Targeting AR-ACE2/TMPRSS2 signal axis by proxalutamide could significantly inhibit the entry of the virus into host cells by transcriptionally down-regulating the expression of TMRPSS2 and ACE2. Proxalutamide promotes the clearance of pathogens and decreases inflammation by activating the Nrf2 pathway, which inhibits the over production of IL-6, proinflammatory cytokines, and chemokines. This mechanism of action reduces the intensity of the cytokine response, which may be of clinical benefit to patients with COVID-19 infection.
