NCT ID NCT04661293
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This program offers expanded access to an experimental treatment using a patient's own muscle cells. It is for people with serious or life-threatening conditions who have no other options. Doctors can request the treatment for eligible patients, but it is not yet proven to work.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- autologous muscle derived cells (AMDCs)
- What this could lead to
- If successful, this program could provide a treatment option for patients with serious muscle-related diseases who have no other alternatives.
- What could go wrong
- This is an early expanded access program, not a full clinical trial. The treatment is still investigational, and benefits are not guaranteed. Risks are not fully known.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Eligibility Criteria: 1. The patient has a serious or life-threatening disease or condition with no satisfactory alternative. 2. Positive assessment that the anticipated benefits outweigh the risks to the patient. 3. Positive assessment that Cook MyoSite has an adequate supply of resources for producing the investigational product. 4. A determination that expanded access will not interfere with Cook MyoSite's ability to complete clinical trials in a timely fashion or which might otherwise delay marketing approval and ultimately availability to all patients. 5. The patient can undergo a muscle biopsy procedure(s). 6. The patient can undergo Cook MyoSite's required donor screening and testing.
