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 active and recruiting rare disease 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 58 active clinical trials across 5 development stages, with 33 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 counts the active and recruiting trials listed on this page, from ClinicalTrials.gov. For companies that work outside rare disease, we list only trials for rare diseases we track, so the company's full pipeline may be larger.

RECRUITINGRecently updatedNCT07582276

A Prospective Assessment of Bone Health in Patients With Severe Hemophilia A on Factor VIII vs Factor Mimetic Prophylaxis (Efa Emi Bone Health Study)

This study will compare bone mineral density in patients with severe hemophilia A receiving prophylaxis with emicizumab or efanesoctocog alfa. Participants will undergo assessments of bone mineral density, bone remodeling biomarkers, thrombin generation, plasmin generation, and joint health over a five-year period. The study aims to evaluate whether differences in prophylactic therapy are associated with differences in bone health outcomes.

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 to Test a Medicine (Fitusiran) for Preventing Bleeds in People With Severe Hemophilia Who Previously Received Preventive Treatment With Emicizumab

Intervention: Fitusiran (SAR439774), Clotting factor concentrates (CFC) or bypassing agents (BPA), Antithrombin concentrate (ATIIIC), Emicizumab

This is an exploratory, single group, Phase 4, study to assess treatment with fitusiran prophylaxis after switching from emicizumab prophylaxis. This study aims to evaluate the safety and tolerability of switching to fitusiran after a transition period from the last dose of emicizumab. The study will be conducted in male participants with severe hemophilia A, with or without inhibitors, aged ≥12 years, who were previously receiving emicizumab prophylaxis. Study details include: * The study duration will be up to approximately 28 months: * There will be an approximately 2-month screening period. * There will be an approximately 2-month period before fitusiran treatment starts (pre-fitusiran treatment period) * The fitusiran treatment duration will be up to 18-months (fitusiran treatment period) * The antithrombin (AT) follow-up (FU) period will be approximately 6 months after the last dose of fitusiran (during which the AT activity level will be monitored at approximately monthly intervals following the final fitusiran dose until AT activity levels return to at least 60%). * The study site visits are scheduled at monthly/ every 2 months intervals of 28 days (4 weeks) / 56 days (8 weeks), respectively, during the fitusiran treatment period.

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.

A Study to Investigate the Safety, Tolerability, and Efficacy of SAR446268, an Adeno-associated Viral Vector-mediated Gene Therapy in Participants Aged 10 to 55 Years of Age With Non-congenital Myotonic Dystrophy Type 1

Intervention: SAR446268

This is a Phase 1/Phase 2 open-label single arm, multicenter, and multinational study with SAR446268 for treatment of male and female participants 10 to 55 years old with non-congenital myotonic dystrophy (DM) type 1 (DM1). The purpose of this study is to evaluate the safety and efficacy of SAR446268 in knocking down dystrophia myotonica protein kinase (DMPK) messenger ribonucleic acid (mRNA) levels and improving neuromuscular function in DM1 participants receiving a single intravenous (IV) administration of SAR446268. The study consists of a dose escalation part (Part A) during which single ascending doses of SAR446268 will be evaluated in 3 distinct cohorts and an optional fourth dose cohort. Once a safe and effective dose is identified, additional participants will be treated in Part B, the dose expansion phase of the study. The study duration will be 112 weeks (approximately 2 years) for each participant in Parts A and B respectively and includes an optional pre-screening period, approximately 8-week screening phase and a 104-week follow-up period post-SAR446268 administration.
