Roche Pharma Day September 28 Preview: Petrelintide, Enicepatide, HM17321 Positioned as Top-Three Global Obesity Portfolio Update Ahead of EASD 2026

Roche (SIX: ROG) is scheduled to hold its Pharma Day investor event Monday September 28, 2026, providing updates across the R&D portfolio including three top-three-position obesity assets: petrelintide (amylin analog partnered with Zealand Pharma under the March 2025 up-to-$5.3 billion collaboration, ZUPREME-1 documented 10.7% weight loss at 42 weeks, Phase 3 monotherapy initiation planned late 2026); enicepatide (CT-388, dual GLP-1/GIP receptor agonist acquired from Carmot Therapeutics in 2023, 54% obesity resolution at 24 mg in Phase 2); and HM17321 (urocortin-2 / CRFR2 receptor agonist peptide licensed from Hanmi Pharm on August 24, 2026 with $190 million upfront plus up to $2.3 billion in milestones plus tiered royalties; Genentech takes over from Phase 2 forward). The Pharma Day briefing frames Roche as a credible third-place global obesity competitor behind Eli Lilly (Zepbound-Mounjaro-Foundayo plus upcoming retatrutide) and Novo Nordisk (Wegovy-Ozempic plus CagriSema plus amycretin), with EASD 2026 Rome September 28-October 2 the immediate downstream data catalyst.

Roche Enicepatide CT388-103 Phase 2 at ADA: 22.5% Placebo-Adjusted Weight Loss at 48 Weeks, 40% Reaching 25% Loss

Genentech presented Phase 2 CT388-103 data for enicepatide, the once-weekly GLP-1/GIP dual agonist, at the Roche investor event Monday June 8. The 48-week study produced 22.5% placebo-adjusted weight loss in adults with overweight or obesity, with 26% of participants losing more than 30% of body weight and almost 40% reaching at least 25%. Both enicepatide and petrelintide advance into Phase 3, and the planned Phase 2 multi-arm fixed-dose combination of the two starts mid-2026.
