Study Endpoints

Primary Endpoints

Assessment of safety of therapy with VCA-894A when administered via intrathecal injection, as measured by the incidence of adverse events.
631 days

Safety will be assessed by determining the incidence, severity, and dose relationship of adverse events that are related to treatment with VCA-894A.

Assessment of CMT2S symptoms following chronic administration of intrathecal VCA-894A, as determined by the change in the Revised Upper Limb Module for Spinal Muscular Atrophy (RULM).
631 days

The Revised Upper Limb Module for Spinal Muscular Atrophy (RULM) scores range from a minimum of 0 to a maximum of 37 points, with higher scores indicating better upper limb function.

Assessment of CMT2S symptoms following chronic administration of intrathecal VCA-894A, as determined by the change in the Hammersmith Functional Motor Scale - Expanded (HFMSE).
631 days

The Hammersmith Functional Motor Scale - Expanded (HFMSE) scores range from a minimum of 0 to a maximum of 66 points, with higher scores indicating greater motor functioning.

Secondary Endpoints

Rescue of IGHMBP2, as determined by the change in IGHMBP2 mRNA expression from baseline.

Frequently asked questions about VCA-894A

What is VCA-894A used for?

VCA-894A is an investigational small molecule being developed for the treatment of Charcot Marie Tooth Disease (CMT), a group of inherited neurological disorders affecting the peripheral nerves. It is specifically being studied for axonal type 2S (CMT2S), a subtype of the disease. The drug is currently in Phase 1 clinical development.

What does VCA-894A target?

VCA-894A targets IGHMBP2, a protein involved in DNA and RNA metabolism. Mutations in the IGHMBP2 gene are associated with CMT2S, a form of Charcot Marie Tooth Disease. By targeting this protein, the drug aims to address the underlying genetic cause of the condition.

Who is developing VCA-894A?

VCA-894A is being developed by Vanda Pharmaceuticals Inc., a biopharmaceutical company traded on the NASDAQ under the ticker symbol VNDA. The company is conducting clinical research on this drug for the treatment of Charcot Marie Tooth Disease.

What phase is VCA-894A in?

VCA-894A is in Phase 1 clinical development. It is an investigational drug and has not yet been approved by regulatory authorities. The drug has received Orphan Drug and Rare Pediatric Disease designations from the FDA for its intended use in Charcot Marie Tooth Disease.

What clinical trials is VCA-894A in?

VCA-894A is being studied in a Phase 1 clinical trial with the identifier NCT07223632. The trial is titled "Treatment of Charcot-Marie-Tooth Disease, Axonal, Type 2S (CMT2S) in an Individual Patient" and is active but not recruiting. It is an uncontrolled, open-label study enrolling one female patient in the United States.
