Dr. Greg Marchand has served as Principal Investigator on eight industry-sponsored FDA clinical trials in women’s health. Each is listed below with its ClinicalTrials.gov registry identifier, sponsor and phase, so that the protocol and results can be verified independently rather than taken on trust.
Trial work is conducted at the Marchand Institute’s Mesa, Arizona site. It is kept structurally separate from Dr. Marchand’s evidence-synthesis program: no sponsor of a trial funds, reviews or influences any systematic review or meta-analysis he publishes.

How Trial Work Relates to Dr. Marchand’s Independence
Dr. Marchand’s role in the studies above is as a clinical trial site principal investigator: his site enrolls and follows 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, his research program. Dr. Marchand holds no 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 his systematic reviews and meta-analyses. He openly declares no conflicts of interest. Read the full independence and funding statement.
For Sponsors and Investigators
Dr. Marchand considers new site participation in gynecologic surgery, endometriosis, fibroid, contraception and general women’s health trials. Inquiries from sponsors, CROs and academic coordinating centers can be directed to maria@marchandobgyn.com or through his collaboration page.
