Cytokinetics (CYTK) announced that Sanofi (SNY) will acquire exclusive rights to develop and commercialize aficamten from Corxel Pharmaceuticals for the treatment of patients with obstructive and non-obstructive hypertrophic cardiomyopathy in Greater China.

Sanofi will now acquire Corxel’s rights relating to aficamten in Greater China for an undisclosed amount. Cytokinetics remains eligible to receive up to $150M in development and commercial milestone payments from Sanofi as well as royalties in the low-to-high teens on future sales of aficamten in Greater China. Cytokinetics is now also eligible to receive additional undisclosed payments in connection with the execution of the agreement between Sanofi and Corxel.
