Becoming the second drug approved by the U.S. FDA for tenosynovial giant cell tumors, Deciphera Pharmaceuticals Inc.’s oral CSF1R inhibitor vimseltinib, newly branded Romvimza, could take significant market share from a competitor in the same class. A phase III trial showed a higher objective response rate with Romvimza than a separate phase III trial showed with Daiichi Sankyo Co. Ltd.’s Turalio (pexidartinib), and the latter’s label contains a boxed warning on rare but serious and sometimes life-threatening liver side effects.
With Deciphera Pharmaceuticals Inc.’s positive top-line data in hand from the pivotal phase III study called Motion, Wall Street speculation turned to the comparative safety and regulatory odds for vimseltinib (which analysts often refer to as “vim”) in patients with tenosynovial giant cell tumor (TGCT) not amenable to surgery.
