Stephen V Liu: Data from ARROS-1 study of NVL-520 in ROS1 NSCLC
Stephen V Liu shared a post on X:
”Benjamin Besse presents data from ARROS-1 study of NVL-520 (zidesamtinib) in ROS1 non-small cell lung cancer (NSCLC). Recommended Phase 2 Dose (RP2D) established at 100mg daily. Rationally designed drug with high central nervous system (CNS) efficacy and avoiding tropomyosin receptor kinase (TRK) will help reduce toxicity.
Impressive activity of NVL-520 (zidesamtinib) in ROS1 non-small cell lung cancer (NSCLC). Overall response rate (ORR) 44%; in repotrectinib naive setting, response rate (RR) 51%. With ROS1 G2032R, response rate (RR) 72% if repotrectinib naive. Durable responses (median not reached in repotrectinib naive). Strong intracranial efficacy.
Importantly, very favorable safety profile, largely from sparing tropomyosin receptor kinase (TRK) signaling. Main toxicities include edema, aspartate aminotransferase (AST) and alanine aminotransferase (ALT) elevation, weight gain – but none leading to discontinuation and dose reduction rate from treatment-related adverse events (TRAE) only 8%.”
