Novartis has long been committed to understanding and developing treatments for hemoglobinopathies, a group of inherited blood disorders that includes sickle cell disease (SCD). SCD is a life-threatening condition with chronic debilitating manifestations, including acute painful episodes, anemia, organ damage, chronic pain, and fatigue. It is regarded by the World Health Organization (WHO) as a public health priority and a neglected health problem in sub-Saharan Africa, where 80% of babies with SCD globally are born each year1.
Today, Novartis is a leader in addressing critical unmet needs in SCD. We are continually seeking new approaches and strategic partnerships to help make diagnosis and treatment more accessible and affordable to patients in countries where SCD remains a challenge for health care systems.
Building a solid, sustainable foundation
SCD is a global health problem, yet sub-Saharan Africa (SSA) bears the highest burden of disease. To help bridge disease management and outcome disparities between Africa and the rest of the world, Novartis established the Novartis Africa Sickle Cell Disease program. The program is implemented through public-private partnerships with local governments, as well as collaborations with universities, patient groups, professional societies and other organizations. A key element of Novartis strategy is a comprehensive approach to disease management that encompasses early intervention strategies, such as screening and diagnosis; research to investigate new treatments; and education and advocacy to improve access to existing therapies.
The program was launched in Ghana in 2019 and expanded to Angola, Kenya, Tanzania, Uganda and Zambia, with further plans to expand across SSA.
Highlights of the program include:
- Working with partners to make diagnosis more available, accessible and affordable— currently, lack of access to newborn screening, and thus delayed diagnosis, is thought to be a primary driver of mortality for children in Africa with SCD (it is estimated that 50-90% of infants born in Africa with SCD will die before their fifth birthday)2
- Expanding access to hydroxyurea (a generic medicine that has been shown to improve health outcomes of individuals living with SCD), as well as making available a child-friendly formulation (currently launched in Ghana with plans to expand across SSA)
- Helping to strengthen health care systems to provide comprehensive management of SCD, including early interventions and the safe administration of existing and innovative treatments. Novartis supports programs to train healthcare professionals, for example, more than 100 SCD clinics in Ghana and Uganda have been trained to provide SCD care through the Ahodwo program
- Partnering with governments to ensure program sustainability and to support policy changes that lead to long-term improvements in healthcare for patients with SCD
Leveraging technology with the goal of improving outcomes and helping to optimize safety
Novartis comprehensive approach to SCD disease management includes a portfolio of digital initiatives, including information-, advocacy-, and support-oriented websites tailored to country needs, as well as mobile solutions to better serve the global sickle cell community.
For example, as part of the Africa Sickle Cell Disease Program, Novartis supported the Sickle Cell Foundation of Ghana to develop and roll out a digital phone-based application (App) to facilitate collection and management of data in the country’s national newborn screening program. To date, more than 90 000 babies have been registered in the App, which is being expanded to additional countries in Africa. In addition, the partners have developed a clinical management App to help ensure safe and effective use of hydroxyurea. A third App is being tested to provide healthcare professionals with ready access to a digital version of the hydroxyurea prescribing guidelines on their phones.
Addressing understanding: Making education a priority
There’s a world of myths and misconceptions about SCD. Many of them are harmful and create barriers to early diagnosis and treatment.
In 2019, Novartis conducted the Sickle Cell World Assessment Survey (SWAY), one of the largest global surveys in sickle cell disease, which provided valuable information about the impact of the disease on patients and their families and caregivers worldwide4. Insights were collected from more than 2 100 patients and 360 healthcare providers to help inform the management of this lifelong condition. This included more than 500 patients and more than 40 healthcare professionals from Ghana and Nigeria. Here are five things we learned.
Novartis has long sponsored educational initiatives to bridge the voices of those with SCD with the world at large. One is example is notaloneinsicklecell.com, a website available in 15 different languages featuring real stories from patients with SCD from around the globe.
In addition, Novartis works with partners to develop educational content and tools that help inform patients and healthcare providers about the pathophysiology and management of SCD. For example, together with the Global Alliance for Sickle Cell Disease Organizations (GASCDO), Novartis conducted a series of virtual dialogues where healthcare professionals, patients and other key stakeholders in sub-Saharan Africa (SSA) engaged in proactive conversations about SCD and the difficulties patients face in navigating their disease, including topics such as screening and stigma. In addition, in collaboration with the Sickle Cell Disease Association of America (SCDAA), Novartis conducted educational workshops to strengthen the capacity and skills of patient associations across SSA.
Gene therapy: Hope for a cure
While the genetic cause of SCD has been known for decades, only recently has medical science gained the tools to potentially mitigate the biological effects of the errant gene that causes the disease.
In 2021, Novartis entered into a grant agreement with the Bill & Melinda Gates Foundation with the shared goal to discover and develop a novel in vivo gene therapy to cure the clinical manifestations of SCD.
Existing clinical-stage gene-based therapies involve removing cells from a patient, modifying those cells in a laboratory, and then reintroducing them to the patient through a procedure similar to a bone marrow transplant. If approved, this complex procedure may be challenging to introduce in many parts of sub-Saharan Africa due to current limitations of local healthcare systems. The Novartis-Gates Foundation collaboration envisions an in vivo gene therapy administered directly to patients, where the goal would be to mitigate the need for extended hospital stays or specialized infrastructures.
As part of the early drug design strategy, Novartis will prioritize addressing access and distribution hurdles posed by limited healthcare infrastructure in low- and middle-income countries.
At Novartis, we remain committed to providing hope and improving outcomes for anyone affected by SCD. There is more to be done. That is why Novartis continues to join forces with partners from around the world to help bring sickle cell disease out of the shadows.
