ERA-63, also known as ORG-37663, as well as 3-methylene-7α-methyl-17α-ethynylestra-5(10)-en-17β-ol, is a synthetic, steroidal estrogen and a selective agonist of the ERα that was under development for the treatment of rheumatoid arthritis but was never marketed.[2][1] The drug produced estrogenic effects but failed to show effectiveness for rheumatoid arthritis in a phase IIa clinical study.[3][4] A large clinical trial also found that prinaberel (ERB-041), a selective ERβ agonist, was ineffective in the treatment of rheumatoid arthritis in spite of activity in preclinical models.[4]
