- Project brings together Novartis drug discovery and gene therapy expertise and funding support from the Gates Foundationá
- Agreement aims to address disparity in access to treatments and to prioritize populations and regions that bear the greatest burden of sickle cell disease in the search for curative therapies
- Effort expands on Novartis commitment to sickle cell disease, which includes a therapeutic pipeline and a holistic approach to diagnosis, treatment, and management of the disease in sub-Saharan Africa
Basel, February 17, 2021 - Novartis today announced that it has entered into a grant agreement with the Bill & Melinda Gates Foundation. As part of the agreement, the foundation will provide funding support for the discovery and development of a single-administration, in vivo gene therapy to cure sickle cell disease (SCD). The project brings together Novartis drug discovery and gene therapy expertise with the Gates Foundation’s charitable objectives to expand access to healthcare in low-resource settings in an effort to address this potentially life-threatening genetic disease.
"Existing gene therapy approaches to sickle cell disease are difficult to deliver at scale and there are obstacles to reaching the vast majority of those affected by this debilitating disease," said Jay Bradner, a hematologist and President of the Novartis Institutes for BioMedical Research (NIBR). "This is a challenge that calls for collective action, and we are thrilled to have the support of the Bill & Melinda Gates Foundation in addressing this global unmet medical need."
SCD is a hereditary blood disease-one of the oldest known and most common genetic disorders. The disease affects millions around the world, with over 300,000 born with the condition annually1,2. It disproportionately affects those of African descent, and sub-Saharan Africa bears roughly 80 percent of the disease burden3. It also is common among people with ancestry from South America, Central America, and India, as well as several Mediterranean countries, such as Italy and Turkey.
SCD is a complex genetic disorder that affects the structure and function of hemoglobin, reduces the ability of red blood cells to transport oxygen efficiently and, early on, progresses to a chronic vascular disease1,4,5,6. The disease can lead to acute episodes of pain known as sickle cell pain crises, or vaso-occlusive crises, as well as life-threatening complications7,8,9. The resulting, frequent hospitalizations associated with sickle cell disease combined with an overall lack of specialized care places a significant burden on patients and their families, healthcare systems, and the overall economy. Even with today’s best available care, SCD continues to drive premature deaths and disability.
While the genetic cause of SCD has been known for decades, it’s only recently that the medical world has gained the tools to potentially fix the errant gene that causes the disease. Current clinical-stage gene-based therapies require extracting cells from a patient, altering those cells in a laboratory, and then reintroducing them to the patient through a complex procedure akin to a bone marrow transplant. The lab and manufacturing facilities and hospital infrastructure for such procedures often do not exist in the areas where SCD is most prevalent, excluding the vast majority of those with the disease from these life-changing gene therapies.
"Gene therapies might help end the threat of diseases like sickle cell, but only if we can make them far more affordable and practical for low-resource settings," said Trevor Mundel, President of Global Health at the Gates Foundation. "What’s exciting about this project is that it brings ambitious science to bear on that challenge. It’s about treating the needs of people in lower-income countries as a driver of scientific and medical progress, not an afterthought. It also holds the promise of applying lessons learned to help develop potentially curative options for other debilitating diseases affecting low-income populations, such as HIV."
Novartis envisions developing an accessible in vivo gene therapy for SCD that could potentially be administered once, directly to the patient, without the need to modify the cells in a lab. This would have the advantage of mitigating the need for long or repeated hospital stays or specialized lab infrastructure. To facilitate the research, the Gates Foundation has agreed to provide funding support for a research team within NIBR wholly dedicated to developing an approach to delivering this potential treatment. Novartis will provide in-kind support and access to its suite of technologies and resources.
In addition to research funding, the Gates Foundation lends its long history and experience in global health to this collaboration. As part of the early drug design strategy, Novartis will prioritize addressing access and distribution hurdles posed by limited healthcare infrastructure in lowand middle-income countries and the funding agreement includes specific provisions to support global access to any resulting innovations.
"Novartis is proud to lead this effort to find an accessible genetic therapy for sickle cell disease, with support from the Bill & Melinda Gates Foundation," said Lutz Hegemann, Group Head of Corporate Affairs & Global Health for Novartis. "In keeping with our purpose, we firmly believe we can use science and innovation to reimagine the way SCD is treated for patients around the world."
The agreement builds on the Novartis commitment to improve the lives of patients with sickle cell disease through the development of new treatments, including crizanlizumab, strategic partnerships with government and non-government organizations, and support for such interventions as newborn screenings and the distribution of existing drugs.
