How Trial Work Relates to Our Independence
The Institute’s role in the studies above is as a clinical trial site: we enrol and follow participants under a sponsor’s protocol. Site participation is compensated at fair market value for the clinical work performed, as it is at every trial site.
This is separate from, and does not fund, our research programme. Neither the Institute nor Dr. Marchand holds consulting agreements, advisory fees, speaking fees, equity or royalties from any pharmaceutical or medical device company, and no sponsor has any role in selecting, conducting, interpreting or reporting our systematic reviews and meta-analyses. Dr. Marchand openly declares no conflicts of interest. Read the full independence and funding statement.
For Sponsors and Investigators
The Institute considers new site participation in gynecologic surgery, endometriosis, fibroid, contraception and general women’s health trials. Enquiries from sponsors, CROs and academic coordinating centres can be directed to maria@marchandobgyn.com or through our collaboration page.
