NCT ID: NCT04178213 Recruiting - Aortic Stenosis Clinical Trials

First in Human Feasibility Study With ADAPT 3D - ALR for Aortic Leaflet Repair

Start date: March 26, 2020
Phase: N/A
Study type: Interventional

This study will evaluate the safety and performance of the ADAPT 3D - ALR in adult patients requiring replacement of aortic valve. 15 patients in one site in Belgium will all be treated with ADAPT 3D - ALR.

Interventional studies are often prospective and are specifically tailored to evaluate direct impacts of treatment or preventive measures on disease.

Observational studies are often retrospective and are used to assess potential causation in exposure-outcome relationships and therefore influence preventive methods.

Expanded access is a means by which manufacturers make investigational new drugs available, under certain circumstances, to treat a patient(s) with a serious disease or condition who cannot participate in a controlled clinical trial.

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
