Drug Discovery Weekly — April 8, 2026
The most impactful regulatory development this week is Amgen's positive Phase 3 TEPEZZA OBI subcutaneous formulation trial in thyroid eye disease, achieving a 77% proptosis response rate. On the deals front, Gilead Sciences made its biggest splash in oncology in years with a $5 billion acquisition of German ADC biotech Tubulis, while Neurocrine Biosciences simultaneously closed its largest-ever M&A transaction by acquiring Soleno Therapeutics for $2.9 billion. Neurology trial watchers are also closely monitoring a fresh set of early 2026 readouts that could reshape CNS treatment pipelines.
