Frequently asked questions about SRP-1005

What is SRP-1005 used for in Huntington's Disease?

SRP-1005 is an investigational small molecule being developed for the treatment of Huntington's Disease. It is currently in Phase 1 clinical development, meaning it has not yet been approved by regulatory authorities. The drug is being studied in a first-in-human trial to evaluate its effects in participants with Huntington's Disease.

What does SRP-1005 target?

SRP-1005 targets the HTT gene, which is associated with Huntington's Disease. By targeting HTT, the drug aims to address the underlying genetic cause of the condition. This mechanism is being evaluated in early-stage clinical trials to determine its safety and potential efficacy in patients.

Who makes SRP-1005?

SRP-1005 is being developed by Sarepta Therapeutics, Inc., a biopharmaceutical company listed on the NASDAQ under the ticker symbol SRPT. Sarepta is conducting the clinical development of this investigational drug for Huntington's Disease.

What phase is SRP-1005 in?

SRP-1005 is currently in Phase 1 clinical development. It is an investigational drug, meaning it has not been approved by the FDA or other regulatory agencies. The ongoing Phase 1 trial is recruiting participants to assess the drug's safety, tolerability, and effects in people with Huntington's Disease.

What clinical trials is SRP-1005 in?

SRP-1005 is being studied in a single Phase 1 clinical trial registered as NCT07536061. This first-in-human study is recruiting 32 participants with Huntington's Disease across Australia, New Zealand, Switzerland, and the United Kingdom. The trial is randomized, double-blind, and controlled, with participants aged 21 years and older.

Is SRP-1005 the same as any other drug?

SRP-1005 is the sole name provided for this investigational drug; no alternative names have been identified. It is a distinct small molecule being developed by Sarepta Therapeutics for Huntington's Disease and is not known to be identical to any other marketed or investigational product.
