Rybrevant Hits Phase 3 Goals in Some Lung Cancers
Janssen says its Rybrevant (amivantamab-vmjw) met the MARIPOSA-2 dual primary endpoints, showing statistically significant and clinically meaningful improvement in progression-free survival plus chemotherapy with and without lazertinib (Janssen’s Leclaza) versus chemotherapy alone in patients with epidermal growth factor receptor (EGFR)-mutated non-small cell lung cancer after disease progression on AstraZeneca’s Tagrisso (osimertinib). A company statement says MARIPOSA-2 is the first Phase 3 study to show statistically significant and clinically meaningful improvement in progression-free survival in the post-Tagrisso setting.
Rybrevant is described as a fully-human bispecific antibody targeting EGFR and mesenchymal epithelial transition with immune cell-directing activity. It received FDA accelerated approval in 5/2021 to treat adults with locally advanced or metastatic non-small cell lung cancer with EGFR exon 20 insertion mutations, as detected by an FDA-approved test, whose disease has progressed on or after platinum-based chemotherapy.
