David Spigel, MD, director, Lung Cancer Research Program, Sarah Cannon Research Institute, discusses the development of onartuzumab for the treatment of patients with lung cancer.

Onartuzumab showed benefit initially in a phase II trial with regard to progression-free survival (PFS) and overall survival (OS) in combination with erlotinib for patients with refractory MET-positive lung cancer. Onartuzumab also showed activity in other settings in combination with other drugs. A phase III study of about 500 patients, however, showed no advantage to PFS, OS, or response rate.

Another MET inhibitor, tivantinib, also showed no benefit in patients with refractory non-small cell lung cancer.

Several questions remain regarding MET inhibitors, Spigel says, but it is known that the MET signaling pathway is important in oncogenesis.
