ALK mutant | lung non-small cell carcinoma | no benefit | Crizotinib + Onalespib | Phase II | Actionable | In a Phase II trial, Onalespib (AT13387) and Xalkori (crizotinib) combination treatment did not significantly improve median progression free survival (269 vs 266 days) or objective response rate (55.4%, 38/68 vs 45.3%, 31/68) compared to Xalkori (crizotinib) single treatment in patients with non-small cell lung carcinoma harboring either an ALK mutation or ALK rearrangement (J Clin Oncol 34, 2016 (suppl; abstr 9059); NCT01712217). | detail... |
ALK mutant | lung non-small cell carcinoma | no benefit | Belizatinib | Phase I | Actionable | In a Phase I trial, treatment with Belizatinib (TSR-011) in ALK inhibitor-naive non-small cell lung cancer patients (n=14) harboring either an ALK mutation, ALK amplification, or an ALK rearrangement resulted in a partial response in 6 patients and stable disease in 8 patients, however, it was determined that the drug resulted in limited efficacy and development of the drug was discontinued (PMID: 31217479; NCT02048488). | 31217479 |
