Pfizer says EC grants conditional marketing authorization for LORVIQUA
Pfizer announced that the European Commission granted conditional marketing authorization for LORVIQUA as a monotherapy for the treatment of adult patients with anaplastic lymphoma kinase-positive advanced non-small cell lung cancer whose disease has progressed after alectinib or ceritinib as the first ALK tyrosine kinase inhibitor therapy, or crizotinib and at least one other ALK TKI. LORVIQUA is a third-generation ALK TKI that was specifically developed to penetrate the blood brain barrier, in the presence or absence of resistance mutations. The conditional marketing authorization was based on results from a non-randomized, dose-ranging and activity-estimating, multi-cohort, multi-center Phase 1/2 study, B7461001, evaluating LORVIQUA for the treatment of patients with ALK-positive advanced NSCLC, who were previously treated with one or more ALK TKIs. A total of 139 patients with ALK-positive metastatic NSCLC after treatment with at least one second-generation ALK TKI, such as alectinib, brigatinib or ceritinib, were enrolled in the Phase 2 portion of the study. Among these patients, the overall response rate for those who have been treated with one prior ALK TKI was 42.9% and 39.6% for those with two or more prior ALK TKI treatments. In the trial, 67% of patients had a history of brain metastases.
