Overview
Treatment Details
Mechanism of Action
An investigational, orally administered small molecule splicing modulator that promotes inclusion of a "poison exon" in HTT pre-mRNA, leading to reduced production of both mutant and wild-type huntingtin protein — offering a pill-based alternative to injectable or surgical huntingtin-lowering approaches. Being studied in the PIVOT-HD trial, developed in collaboration with Novartis.
Dosing Notes
Investigational; once-daily oral capsule under evaluation in ongoing trials.

Clinical Evidence
What the Evidence Shows
Each finding below is linked to its primary source. Confidence levels reflect the quality and quantity of available evidence — not CelluTarget's endorsement of any treatment.
High: Supported by multiple robust studies or regulatory approval
Moderate: Supported by limited controlled studies or consistent case series
Low: Based on case reports, expert opinion, or early-phase data only
Moderate ConfidenceSupported by limited controlled studies or consistent case series
PIVOT-HD Phase 2 data has shown dose-dependent reduction in huntingtin protein levels with an oral, once-daily regimen — a potential convenience advantage over injectable or surgical huntingtin-lowering approaches. An extension study is evaluating long-term safety and efficacy.
