About Ropotrectinib (TPX-0005)

Ropotrectinib (TPX-0005) is a potent and orally bioavailable investigational small molecule kinase inhibitor for ALK, ROS1, and TRK family. The clinical benefits of targeting ALK, ROS1, or TRK fusion kinase have been demonstrated with multiple kinase inhibitors already approved for the treatment of ALK+ non-small cell lung cancer (NSCLC), in addition to crizotinib for ROS1+ NSCLC, and larotrectinib and entrectinib in clinical studies for TRK+ cancers. The successes of these therapies are overshadowed by the development of acquired resistance. The acquired solvent front mutations including ALK G1202R, ROS1 G2032R, TRKA G595R and TRKC G623R render a common clinical resistance to the current ALK, ROS1, and TRK inhibitors. TPX-0005 is a potent kinase inhibitor against wildtype and mutated ALK, ROS1 and TRK family kinases, especially the clinically significant solvent front mutations, gatekeeper mutations, and emerging compound mutations after multiple line treatments. Ropotrectinib may provide new opportunities in the clinic to inhibit the abnormal signaling of ALK, ROS1, or TRK family in solid malignancies, and overcome resistance seen in refractory patients. TPX-0005 is currently being evaluated in a Phase 1/2, open-label, multi-center, first-in-human study of the safety, tolerability, pharmacokinetics and anti-tumor activity in patients with advanced solid tumors harboring ALKROS1, or NTRK1-3rearrangements (TRIDENT-1, NCT03093116).
