What this study is testing
What is Temsirolimus?
Temsirolimus is an investigational medicine, given as an injectable medicine, being studied as a potential treatment for peripheral artery disease.
Plain-language explanation of the investigational treatment. It is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- This study is testing whether a drug injection helps keep leg arteries open. It looks at how well it works and how safe it is.
- Who it's for
- You may be able to join if you have serious blockages in your leg arteries.
- What's involved
- You would get an injection of the drug or a pretend treatment. You would also have regular check-ups and tests.
- Time commitment
- The study lasts up to five years with visits after your procedure.
- Phase 3: a large, late-stage study
- Time commitment: about 5 years
- You might receive a placebo (an inactive treatment) instead of the study drug, decided by chance. You may not know which one you got.
