AstraZeneca's Cancer drug Patent Plea Rejected in India

In a setback to AstraZeneca, the Intellectual Property Appellate Board (IPAB) has dismissed its appeal against an earlier ruling that refused it a patent on lung cancer drug Gefitinib. The Indian patents office in 2007 refused patent protection to AstraZeneca, citing lack of invention. The Intellectual Property Appellate Board (IPAB) now upheld the refusal.

In its appeal, Astra Zeneca earlier had argued the controller had erred on various aspects of patent determination and also in concluding that the comparison test did not establish increased efficacy of the drug.

Innovators  suffered a reversal in March when India granted the first ever compulsory licence to Natco Pharma to sell Bayer's cancer drug Nexavar  equiavalent. Bayer has appealed  against the order.

And early this month IPAB revoked a six-year-old Indian patent granted to Roche's hepatitis C drug Pegasys, citing lack of evidence that the drug was any better than existing treatments.
