Study Endpoints

Primary Endpoints

Change in Dystrophin Expression From Baseline Following Treatment With Either AMONDYS 45 (Previously Casimersen), EXONDYS 51 (Previously Eteplirsen ), or VYONDYS 53 (Previously Golodirsen)
Baseline, 1 year

This will be assessed by the comparison of quantification of protein in muscle biopsy tissue by western blot from baseline to 1 year post-initiation of treatment.

Monitoring for the Development of Unacceptable Toxicity.
1 year

This will be measured by capturing and reviewing Adverse Events as defined by CTCAE v4.0.

Secondary Endpoints

Change in Dystrophin Expression From Baseline Following Treatment With Either AMONDYS 45 (Previously Casimersen), EXONDYS 51 (Previously Eteplirsen ), or VYONDYS 53 (Previously Golodirsen).

Frequently asked questions about Amondys 45

What is Amondys 45 used for in Duchenne Muscular Dystrophy?

Amondys 45 is an investigational small molecule being developed for the treatment of Duchenne Muscular Dystrophy (DMD). It is being studied in patients who carry eligible DMD duplications. The drug is currently in Phase 2 clinical development and has not been approved by regulatory authorities.

Who makes Amondys 45?

Amondys 45 is being developed by Sarepta Therapeutics, Inc., a biopharmaceutical company traded on the NASDAQ under the ticker symbol SRPT. The company is conducting clinical trials to evaluate the drug's efficacy and safety in patients with Duchenne Muscular Dystrophy.

What phase is Amondys 45 in?

Amondys 45 is currently in Phase 2 clinical development. It is an investigational drug and has not yet received regulatory approval. The drug is being studied in a completed Phase 2 trial that evaluated its efficacy and safety in patients with Duchenne Muscular Dystrophy.

What clinical trials is Amondys 45 in?

Amondys 45 has been studied in one clinical trial with the identifier NCT04179409. This was a 48-week, open-label, Phase 2 study that evaluated the efficacy and safety of Amondys 45, along with other drugs, in subjects with Duchenne Muscular Dystrophy carrying eligible DMD duplications. The trial has been completed.

Is Amondys 45 the same as EXONDYS 51 or VYONDYS 53?

Amondys 45 is not the same as EXONDYS 51 or VYONDYS 53. These are three separate drugs that were evaluated together in a single clinical trial (NCT04179409) for the treatment of Duchenne Muscular Dystrophy. Each drug targets different genetic mutations in the DMD gene.
