OSI Pharmaceuticals, Inc has completed enrolment in the RADIANT study, a phase-III clinical trial testing Tarceva (erlotinib) as an adjuvant therapy in patients with Stage IB-IIIA non-small cell lung cancer (NSCLC) who have undergone surgery and have EGFR-positive tumours. RADIANT is an international, randomized, double-blinded, placebo-controlled phase-III study that has reached its enrolment goal of 945 patients. The primary objective of the study is to determine whether the targeted therapy Tarceva prolongs disease-free survival when given as an adjuvant therapy. This is defined as a cancer treatment that is given after the primary treatment, which is typically surgery or surgery and chemotherapy in this group of NSCLC patients, to lower the risk of the cancer coming back.

"We believe an oral therapy like Tarceva can be a valuable addition to the treatment paradigm by extending the disease-free survival of patients with Stage Ib-IIIa NSCLC," said Colin Goddard, chief executive officer of OSI Pharmaceuticals. "The study has received considerable interest from both investigators and patients and we look forward to the potential for interim results in 2012 and final results in 2013-2014."

Tarceva is a once-a-day pill that targets the EGFR pathway. Tarceva is designed to inhibit the tyrosine kinase activity of the EGFR signalling pathway inside the cancer cell, one of the critical growth factors in NSCLC and pancreatic cancer.
