Progress Across R&D Portfolio — Votoplam and Other Programs
Positive Phase II PIVOT-HD results for votoplam; FDA end-of-Phase-II alignment reached on Phase III INVEST-HD design. Novartis will initiate INVEST-HD in H1 2026 (target ~770 participants, 3:2 randomization, planned interim efficacy/futility analysis). Additional programs advancing: RNA splicing candidates, MSH3 development candidate election, NLRP3 Phase I initiation by mid-2026, and progression of ferroptosis/NRF2 programs.
Favorable Payer and Real-World Dynamics for Sephience
Payers have generally supported open Sephience access (few barriers, limited/no step edits, refills up to 12 months). High refill rates and low single-digit discontinuation rates reported; social media and patient advocacy driving awareness and demand, including re-engagement of 'lost to follow-up' adults.
