Gender clinical trials

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.

TAVI and Gender Outcomes Aortic Stenosis Undergoing Transfemoral Transcatheter Aortic Valve Implantation.

Start date: January 2007
Phase:
Study type: Observational [Patient Registry]

Severe aortic stenosis (AS) is the commonest form of valvular abnormality in the developed world and transcatheter aortic valve implantation (TAVI) is now widely practiced as in many cases is the preferred treatment option over conventional aortic surgery. Several studies have shown that females have an apparent better outcome with TAVI than males. There are a number of possible reasons as to the apparent favourable benefit of TAVI in women including: having both lower rates of moderate / severe aortic regurgitation and peri-procedural mortality, lower rates of bleeding and renal failure, better patient prosthesis match and recovery of left ventricular function with more favourable left ventricular remodelling. We aim to explore the long term outcomes of TAVI between males and females to try and identify specific tailored treatment options. This data will be useful in providing important information regarding gender differences in patients who are treated with transcatheter aortic valve implantation. Data provided will include long term outcomes and predictors of outcome. The study team will then identify and implement strategies to improve outcomes in patients being treated with transcatheter aortic valve implantation.
