Study Endpoints

Primary Endpoints

Change from Baseline in cUHDRS score
Baseline, Month 36

The Composite Unified Huntingtons Disease Ratings Scale (cUHDRS) is an improved composite measure to assess multi-domain clinical progression in HD. The cUHDRS is a combined weighted score of measures of motor function (TMS), cognition (SDMT and SWRT) and overall functional capacity (TFC): cUHDRS = \[(TFC-10.4)/1.9 - (TMS-29.7)/14.9 + (SDMT-28.4)/11.3 + (SWRT - 66.1)/20.1\] + 10. In conjunction with one another, these measures provide a comprehensive, sensitive and specific tool for monitoring disease progression, with lower scores indicating more severe disease. cUHDRS score range from -8 to 25.

Number of Participants With Treatment-emergent Adverse Events (TEAEs)

Frequently asked questions about Votoplam

What is Votoplam?

Votoplam is an investigational small molecule drug being developed by Novartis AG for the treatment of Huntington Disease, a neurological disorder. It is currently in Phase 3 clinical development and has not been approved by the FDA. Votoplam is also referred to in some study materials as Votoplam (blinded).

What is Votoplam used for in Huntington Disease?

Votoplam is being studied as a treatment for Huntington Disease, a progressive neurological condition. It is an investigational therapy in Phase 3 development and is not approved for any indication. Its efficacy and safety in Huntington Disease are still being evaluated in controlled clinical trials.

Who makes Votoplam?

Votoplam is developed by Novartis AG, which trades under the ticker NVS. Novartis is sponsoring the clinical development program for Votoplam in Huntington Disease, including a Phase 3 study and a long-term extension study.

What phase is Votoplam in?

Votoplam is in Phase 3 clinical development for Huntington Disease. It is investigational and has not received FDA approval. The Phase 3 study is currently recruiting, while a separate long-term extension study is active but no longer recruiting participants.

What clinical trials is Votoplam in?

Votoplam is being evaluated in two clinical trials for Huntington Disease. The Phase 3 trial NCT07326709 is recruiting and plans to enroll 770 participants across 27 countries. The Phase 2 extension study NCT06254482 is active but not recruiting and has enrolled 144 participants. Both are randomized, double-blind, and controlled.

Is Votoplam the same as Votoplam (blinded)?

Yes, Votoplam (blinded) is an alternative name used for Votoplam. Both names refer to the same investigational small molecule developed by Novartis AG for Huntington Disease. The blinded designation reflects the double-blind design of the clinical trials, in which treatment assignment is masked.
