10 Pivotal Clinical Trials to Watch in H1 2026
BioPharma Dive identifies 10 pivotal clinical trials 2026 expected in H1, spanning obesity, infectious diseases, rare disorders, and cardiology. These phase 3 trials to watch could redefine treatments, with Nature Medicine highlighting 11 shaping medicine overall.[https://www.biopharmadive.com/news/biotech-pharma-clinical-trials-watch-2026/808255/][https://www.nature.com/articles/s41591-025-04083-x]
-
Eli Lilly’s Triumph-1, -2, -3 (retatrutide obesity trial): Triple agonist targets GLP-1, GIP, glucagon in over 5,000 obese patients, including diabetes and CVD subgroups. Phase 3 data mid-year could surpass Zepbound’s 21% weight loss, shown at 29% in knee osteoarthritis, transforming metabolic care.
-
Merck-Cidara’s ANCHOR (CD388 flu prevention): Antiviral prevents flu in 6,000 high-risk participants. Mid-stage prevented symptoms in 75%; $9B acquisition signals $5B market if interim Q1 succeeds against seasonal strains.
-
Regenxbio’s Affinity Duchenne (RGX-202): Gene therapy produces enhanced microdystrophin. Early data met accelerated approval thresholds; Phase 3 could differentiate from Elevidys amid FDA scrutiny.
-
Novartis’ Lp(a) Horizon (pelacarsen): RNA therapy lowers Lp(a) in 8,000 CVD patients. Event-driven results could validate inflammation target beyond LDL, boosting rivals like Amgen.
-
Intellia’s Haelo (lonvo-z angioedema): CRISPR one-time edit for hereditary angioedema. Phase 3 tests ‘functional cure’ reducing attacks durably.
-
Vertex’s Rainier (povetacicept IgA nephropathy): Dual-target biologic interim could support accelerated approval, expanding to other kidney diseases.
-
Sarepta-Arrowhead’s SRP-1001/1003: RNAis for FSHD and myotonic dystrophy; early safety data critical for pipeline.
-
Compass’ COMP005/006 (psilocybin depression): Psychedelic hits primary endpoint; 26-week data accelerates approval path.
-
Cytokinetics’ Acacia-HCM: Myqorzo in non-obstructive HCM; could claim full-spectrum dominance over Camzyos.
-
Sionna’s Precision CF: CFTR stabilizers challenge Vertex; add-on to Trikafta tests residual need.
These clinical trials 2026 promise biotech momentum, informing protocols and investments.
