Molecular Partners' Covid-19 therapy proves inactiv

Ensovibep has become the latest Covid-19 treatment candidate to crash out of the NIH-sponsored Activ-3 basket trial, wiping 34% off Molecular Partners’ share price. A planned futility analysis of the cohort evaluating ensovibep, a darpin Molecular Partners licensed to Novartis, concluded that enrolment should be stopped. Activ-3 is looking at potential therapies for hospitalised patients, but no agent in the trial has yet succeeded. The study's clinicaltrials.gov entry was also edited this month to state that Astrazeneca’s MAb combo AZD7442 was no longer being administered either, but no explanation has been offered for this.
