It’s in the brain: An opinionated take on NEJM highlights for April 2019

He’s dead, Jim As previously widely advertised, the BACE-1 inhibitor verubecestat (Merck) (and in journal correspondence atabecestat, Janssen) has now failed in a population with very early signs of cognitive impairment (this after a failure of those agents in mild-moderate Alzheimer’s). Target engagement clearly occurred with a decline of the amyloid detected through PET imaging in the treatment arms and an increase in the placebo arm. However, if anything, cognition declined more in the treatment arm than in the placebo arm after 2 years on study. A silver lining is

Two steps forward, one step back: an opinionated take on NEJM highlights for January 2018

Playing chess against cancer Tumors are not intelligent, but, because they have escaped mutational control, they constantly probe for mutations that will allow them to escape chemotherapeutic suppression. The epidermal growth factor receptor (EGFR) is a frequent driver of malignancy in the lung and as such, a target for EGFR inhibitors such as erlotinib (Tarceva, Roche) or gefitinib (Iressa, Astra Zeneca); unfortunately, tumors initially responsive to these agents quickly develop mutations which make them resistant. Osimertinib (Tagrisso, Astra Zeneca) was designed to overcome the most common resistance mutations and has
