The race to develop an oral selective estrogen receptor degrader (SERD) is under fresh scrutiny in light of Sanofi SA’s decision to axe development of its late-stage compound amcenestrant on Aug. 17, citing lack of efficacy in breast cancer trials. While there are concerns about the new class after Sanofi’s decision, a clear signal about its future could be growing nearer. The driver? Menarini Group and its development partner, Radius Health Inc., are advancing elacestrant, an oral SERD into regulatory reviews on both sides of the Atlantic.
Sanofi SA has terminated development of amcenestrant, an oral selective estrogen receptor degrader (SERD), following an interim analysis of data from a phase III trial in estrogen-receptor-positive advanced breast cancer patients. The company has also halted all other studies of the drug, including a phase III study in patients with early stage breast cancer.
