Olema Pharmaceuticals, Inc., OLMA
The real story came from Swiss pharmaceutical giant Roche. The drugmaker revealed positive Phase III trial data for giredestrant, an investigational breast cancer treatment.
Roche’s study targeted patients with estrogen receptor-positive, HER2-negative, early-stage breast cancer. The trial used giredestrant as an adjuvant endocrine treatment.
The study achieved its primary endpoint during interim analysis. Overall survival data has not yet been released.
Why This Matters for Olema

Roche’s positive results provide validation for this drug class. Investors viewed the news as a positive signal for Olema’s development program.
