Focus areas at Sanofi / Genzyme

Within its broader pharmaceutical portfolio, Sanofi / Genzyme has active clinical trial programs and drug development efforts across 54 rare diseases, including Alpha-1 Antitrypsin Deficiency, Alport Syndrome, Amyotrophic Lateral Sclerosis, Aplastic Anemia, Becker Muscular Dystrophy, and 49 additional rare conditions. These programs may span orphan drug designation, novel therapeutic mechanisms, and precision medicine approaches targeting the underlying causes of each disease.

The clinical trials section below shows all active and recruiting studies sponsored by Sanofi / Genzyme, sourced live from ClinicalTrials.gov. Each trial includes its current recruitment status, study phase (Phase 1 through Phase 4), conditions under investigation, and the number of active trial sites. The FDA-approved drugs section lists treatments that have received U.S. Food and Drug Administration approval, with brand names, generic names, approval dates, and matched rare disease indications from the openFDA database.

Sanofi / Genzyme is headquartered in Paris, France, founded in 1981, publicly traded under the ticker symbol SNYNF. The company maintains a dedicated rare disease division alongside its broader therapeutic portfolio, working to bring innovative treatments to patients with conditions that have historically had limited or no treatment options.

Sanofi / Genzyme Drug Pipeline

Sanofi / Genzyme has 41 active clinical trials across 5 development stages, with 41 currently recruiting participants. Clinical trials advance through phases: Phase 1 tests safety in a small group, Phase 2 evaluates effectiveness and side effects, Phase 3 confirms benefit in a larger population, and Phase 4 monitors long-term safety after FDA approval.

Note: This pipeline includes all of Sanofi / Genzyme's active interventional trials, not only those targeting rare diseases. We show the full pipeline because a company's broader research activity, therapeutic expertise, and development infrastructure directly shape its ability to advance rare disease programs. A strong overall pipeline often signals deeper clinical operations, faster enrollment capabilities, and greater commitment to bringing new treatments to patients.

RECRUITINGPHASE3Recently updatedNCT07112378

A Study of Dupilumab in Small Children With an Allergic Condition of the Esophagus (Food Pipe): Eosinophilic Esophagitis

Intervention: dupilumab

This study is researching an experimental drug called dupilumab (called "study drug"). The study is focused on children with active eosinophilic esophagitis (EoE; an inflammatory disease of the esophagus) which impacts feeding and nourishment. The aim of the study is to see how safe, tolerable, and effective the study drug is when given for 24 weeks to children with active EoE. The study is looking at several other research questions, including: * What side effects may happen from taking the study drug * How much study drug is in the blood at different times * Whether the body makes antibodies against the study drug (which could make the drug less effective or could lead to side effects)

A Study to Evaluate Impact of Efanesoctocog Alfa on Long-term Joint Health in Participants With Hemophilia A in Taiwan

Intervention: Efanesoctocog alfa

This is a national, multicenter, retrospective/prospective, observational study in Taiwan designed to assess effectiveness, safety, and usage of efanesoctocog alfa prophylaxis treatment in hemophilia A participants. The data related to efanesoctocog alfa effectiveness, safety and usage will be recorded prospectively during routine visits for up to 5 years following enrollment initiation and the retrospective data will be collected at least 12 months and up to 24 months prior to efanesoctocog alfa initiation. Joint imaging data will be collected in centers performing Joint U/S and/or MRI (≥6 years old). At least 12 months of retrospective data will also be collected from medical records, as available. Prospectively collected data will be recorded at routine clinical visits during a five-year follow-up period. The end of study is defined as the last participant's last visit. No intervention will be administered, and no study related visits are required.

A Repeated Dose-finding Study of Sarilumab in Children and Adolescents With Systemic Juvenile Idiopathic Arthritis (SKYPS)

Intervention: Sarilumab SAR153191 (REGN88)

Juvenile Idiopathic Arthritis

Primary Objective: To describe the pharmacokinetic (PK) profile of sarilumab in patients aged 1-17 years with Systemic Juvenile Idiopathic Arthritis (sJIA) in order to identify the dose and regimen for adequate treatment of this population. Secondary Objective: To describe the pharmacodynamics (PD) profile, the efficacy, and the long term safety of sarilumab in patients with sJIA.

A Study of Belumosudil in Children With Chronic Graft Versus Host Disease (schoolROCK)

Intervention: Belumosudil, Belumosudil

This is an open-label, single group, Phase 1/2, 1-arm study for treatment of children aged 1 to \<18 years with active moderate-to-severe cGVHD that is refractory to or recurred after at least 2 prior lines of systemic therapy for cGVHD. The purpose of Phase 1 is to determine the PK profiles and to establish the Recommended Pediatric Equivalent Dose (RPED) of belumosudil in participants aged 1 to \<12 years with active moderate to severe cGVHD. Upon completion and evaluation of Phase 1, Phase 2 will commence with the purpose of determining safety and efficacy (ORR by 24 weeks) of belumosudil in participants aged 1 to \<18 years. Study details include: The end of study is defined as 3 years after the last participant is recruited or all participants have discontinued treatment, or have died, whichever comes first. Minimum of 6 participants ages 1 to 6 years will be enrolled for each phase of study Individual participant duration on study will consist of: Up to 4 weeks for screening. Treatment until clinically significant progression of cGVHD, relapse/recurrence of the underlying disease, start of a new systemic treatment for cGVHD, experience of an unacceptable adverse event, request from participant or Investigator, or until the end of the study is reached, whichever comes first. 30 days of post treatment safety follow-up. Long-term follow-up until death or end of study, whichever occurs first.

Phase I/II Study of Anti-CD38 Monoclonal Antibody in Refractory Severe Aplastic Anemia

Intervention: Isatuximab

This is a phase I/II clinical study in adult patients with refractory severe aplastic anemia (SAA). Eligible patients must meet the criteria for refractory SAA and have a platelet count (PLT) \<30 × 10\^9/L and/or hemoglobin (HGB) \<90 g/L at enrollment. If the phase I results demonstrate an acceptable safety profile and allow determination of the maximum tolerated dose (MTD), the phase II part will be initiated directly to evaluate the efficacy of isatuximab.

Non-inferiority Study of Frexalimab Subcutaneous Administration Compared to Intravenous Administration in Adult Participants With Multiple Sclerosis

Intervention: Frexalimab, Frexalimab, MRI contrast-enhancing preparations

This is a randomized, open-label, parallel, Phase 3 study with 2-arms for treatment. The purpose of this study is to evaluate SC administration of frexalimab every 4 weeks (q4w) compared to IV administration of frexalimab q4w in male and female participants with RMS and nrSPMS (aged 18 to 60 years at the time of enrollment). People diagnosed with MS are eligible for enrollment as long as they meet all the inclusion criteria and none of the exclusion criteria. Study details include: The study intervention duration will be 48 weeks (12 months) for Parts A and B combined. Optional Part C will last until the initiation of a long term safety study for Frexalimab.The follow up duration after the end of study intervention (in case of discontinuation) will be 6 months. The number of scheduled visits (Parts A and B) will be 17 for participants receiving frexalimab SC or IV, with an on-site visit frequency of every month between Week 4 and Week 24 in Part A, then every 1 to 3 months in Part B, then every 6 months in Part C. Participants discontinuing treatment before the End of Study will have an additional 3 follow-up visits.
