Amgen reported 5% year-over-year revenue growth to $6.5bn in the second quarter, up 11% from Q1. It did not break out Lumakras sales but detailed upcoming data that may support future indications.
Remaining questions after ASCO include whether Lumakras (sotorasib) might work in first-line NSCLC with certain co-mutations and if ocular toxicities will hamper bemarituzumab in gastric cancer.
Commercial EVP Murdo Gordon said launching sotorasib during the pandemic is a tougher challenge than encouraging doctors to screen lung cancer patients for KRAS G12C mutations and raising patient awareness.
