Rare Diseases



Focusing on uncommon and underserved medical conditions, our Rare Disease franchise is committed to empowering the lives of patients with rare diseases by offering sustainable, transformative healthcare options.

Built up over the years through both in-house development and strategic acquisitions and partnerships, our Rare Disease franchise focuses on medical areas including lysosomal storage disorders and endocrinology.

Our work includes the use of gene-based applications for a variety of rare disorders. For example, our industry-leading gene therapy work explores how gene manipulation can address patients with inherited neurodegenerative and ophthalmological diseases. We also develop partnerships with investigators in academia and industry to advance the development of this therapeutic concept.

Every part of our Rare Disease franchise serves small patient populations through personalized care and highly specialized products.

Pioneering Research to Lysosomal Storage Disorders

Lysosomal Storage Disorders (LSDs) - a group of rare genetic conditions caused by enzyme deficiencies - are a cornerstone of Sanofi Genzyme's business, and the medical area for which we are most well-known. These disorders are known as ‘orphan diseases’ and affect only a few thousand people worldwide.

Our first ten years of research focused primarily on finding a treatment for a LSD called Gaucher disease, which established our leadership in the rare disease community. Over the next 2 decades we  expanded our focus to include other LSDs including Fabry disease, Pompe disease and Mucopolysaccharidosis I (MPS I).

Our breakthrough work in genetic engineering and recombinant DNA manufacturing has made possible the large-scale production of enzyme replacement therapies (ERTs). ERTs work by breaking down the fatty substance that accumulates in peripheral cells due to the lack of native enzyme.

Ongoing Innovation

Moving forward, we continue to focus on LSDs and addressing unmet needs among these communities. We're researching Niemann-Pick disease, which currently has no treatments available, as well as next-generation therapies for other LSDs. We’re also applying our genetic expertise to new forms of treatment delivery. For example, oral therapies, as compared to traditional intravenous infusion therapies.

We recently entered into a partnership with Alnylam Pharmaceuticals to co-develop and co-commercialize several investigational compounds for rare genetic diseases. These investigational products are a new class of therapeutics based on RNA interference. RNAi, also known as “gene silencing,” works by inhibiting the production of proteins that cause or contribute to the targeted disease. This partnership combines Alnylam’s expertise in this technology platform with our strong clinical development, commercial organizations, and established global infrastructure in rare diseases, helping us to continue to meet unmet needs in this patient community.

Endocrinology

We are committed to addressing unmet needs in the thyroid cancer community. Our expertise in this space includes supporting diagnosis, treatment, and ongoing monitoring for certain thyroid cancers. We continue to advance the science in this area by investing in research and development. 

Supporting Services

Because of the rarity of most of the diseases Sanofi Genzyme treats, the patient and health care communities are small – often with limited resources. To support them, we are committed to providing services that complement our therapies.

  • We provide many U.S. patients with case managers to help navigate the intricacies of insurance, and we have numerous programs worldwide to facilitate patient access to treatment.
  • By establishing registries – large, often multinational databases to which physicians contribute clinical data on patients – for several LSDs, we help pool knowledge and improve understanding of rare diseases that would be otherwise difficult to study 
  • We develop a wide variety of educational materials, both in print and online, for patients and their families as well as health care professionals 
  • Our Patient Advocacy group is deeply involved in the patient communities, working to understand and advocate for their needs 
  • Our Medical Information team is dedicated to answering questions about the diseases we treat, our products, and other genetic issues 
  • Around the world, we partner with local patient organizations to support and advocate for the needs of their patient communities

Our Vision

Our vision is that by 2025, all patients with the rare diseases that we serve will have access to an early diagnosis and appropriate treatment.

Sanofi Genzyme Support Services
U.S. Rare Genetic Diseases

As part of our commitment to the rare genetic disease community, we offer personalized and confidential online support services to people living in the U.S. who are affected by Gaucher disease, Fabry disease, Pompe disease, or MPS I disease.

Newborn Screening for Rare Diseases

Early diagnosis is important for progressive diseases. For more than 15 years, Sanofi Genzyme and our partners have been working to make newborn screening for rare diseases a reality.
