AZD9291 AURA Study World LungSydney – AstraZeneca AZD9291 is now ahead of Clovis Oncology CO-1686 in the race to bring a third-generation epidermal growth factor receptor (EGFR) inhibitor to market that targets the T790M resistance mutation.

That is the conclusion I took from the updated preliminary phase 1 data for the AURA study of AZD9291 in non-small cell lung cancer (NSCLC) presented today at the 15th World Conference on Lung Cancer in Sydney, Australia.  Clovis Oncology presented updated phase 1 data for CO-1686, their third-generation EGFR inhibitor, in Sydney earlier this week.

EGFR inhibitor resistance occurs in most NSCLC patients within 10-11 months with approx. 50-60% developing a gatekeeper mutation called T790M.

There are no approved treatments for NSCLC patients with T790M mutations, so this unmet medical need represents a large commercial market opportunity.

Why do I think that AstraZeneca are now ahead of Clovis Oncology and what does the World Lung data show for both drugs?
