Safety results from the EORTC study[1]

EORTC 26101 was a multicenter, randomized, open-label study in patients with recurrent GBM following radiotherapy and temozolomide, of whom 278 patients received at least 1 dose of Avastin and are considered safety evaluable. Patients were randomized (2:1) to receive Avastin (10 mg/kg every 2 weeks) with lomustine or lomustine alone until disease progression or unacceptable toxicity. The demographics of the safety population were similar to the demographics of the efficacy population. In the Avastin with lomustine arm, 22% of patients discontinued treatment due to adverse reactions compared with 10% of patients in the lomustine arm. In patients receiving Avastin with lomustine, the adverse reaction profile was similar to that observed in other approved indications.[1]
