About Sanofi\'s Trial Portfolio
Sanofi is an industry sponsor — typically a pharmaceutical, biotechnology, or medical device company. Industry sponsors fund and run the largest share of registered trials in the United States and are subject to FDA registration requirements under the FDA Amendments Act (FDAAA 801) for most drug and device studies.
16 of Sanofi's 16 registered trials are currently recruiting — roughly 100% of the portfolio. A high recruiting share usually points to an active research pipeline with multiple programs at the enrollment stage.
Sanofi's research footprint spans Hemophilia A (2 trials), Systemic Lupus Erythematosus (SLE) (1), and Rheumatoid Arthritis (ra) (1) as the top three conditions. The full condition list, sorted by trial count, is in the sidebar.
is the largest single phase in Sanofi's portfolio at 25% of registered trials. The full phase breakdown appears in the sidebar.

How to Approach a Trial Listing
Each trial card above links to a dedicated page with the official ClinicalTrials.gov data plus a plain-English translation of the eligibility criteria. We translate technical terminology (ECOG performance status, hepatic function values, exclusionary lab thresholds) into language that a patient or caregiver can understand, but the original clinical text and the live ClinicalTrials.gov record always govern any actual eligibility decision.
Before contacting a trial site, write down questions for your treating physician using the framework on our 25 Questions guide. Discuss whether the trial fits your treatment plan, what the time commitment looks like, and whether your insurance will cover the standard-of-care portions. Trials are not a substitute for a treatment plan — they are an addition that needs medical guidance to evaluate.

Frequently Asked Questions
How many clinical trials does Sanofi have on ClinicalTrials.gov?
Sanofi has 16 clinical trials registered on the federal ClinicalTrials.gov registry, of which 16 are actively recruiting participants right now. These counts come directly from the ClinicalTrials.gov API and are updated as the registry changes.
What conditions does Sanofi study?
Sanofi's registered trials cover 19 conditions on ClinicalTrials.gov, led by Hemophilia A (2 trials), Systemic Lupus Erythematosus (SLE) (1 trial), Rheumatoid Arthritis (ra) (1 trial), Type 1 Diabetes (1 trial), Type 1 Diabetes Mellitus (1 trial). The complete condition list appears in the sidebar of this page; each condition links to a page listing every recruiting trial in that area, regardless of sponsor.
How do I join a Sanofi clinical trial?
Joining a clinical trial is a medical decision that should always involve your treating physician. Each trial page on this site includes the eligibility criteria translated into plain English alongside the official clinical text, plus the contact information that the sponsor has registered with ClinicalTrials.gov. Bring the trial information to your doctor before reaching out — they can review the full inclusion and exclusion criteria against your medical history and help you decide whether to pursue screening.
What does the trial phase mean?
Phase 1 trials test safety and dosing in small groups (often 20–80 healthy volunteers or patients). Phase 2 trials evaluate efficacy and side effects in larger groups (100–300 patients with the target condition). Phase 3 trials confirm efficacy and monitor safety in the largest groups (300–3,000+ patients) and form the basis of an FDA approval submission. Phase 4 studies happen after a treatment is approved, monitoring long-term safety and effectiveness in real-world use. Some trials register without a phase — common for device, behavioral, or observational studies.
Where does this trial data come from?
All trial data is pulled directly from the ClinicalTrials.gov API v2, the official federal trial registry maintained by the National Library of Medicine at NIH. Under FDAAA 801, most U.S. drug and device trials are required to register, making ClinicalTrials.gov the most comprehensive source. Sponsors are responsible for keeping their listings current; trial status can shift between data refreshes.
How This Sponsor Page Is Built
