Is access to high-quality care for complex, chronic diseases improving in your local area?

Life expectancy for patients with sickle cell disease has surged since the 1970s, with half of all patients living to age 60 or older by 2022. This shift marks a major departure from the 1970s, when life expectancy for those with the condition was under 20 years.

Why it matters

Improved outcomes for the approximately 100,000 Americans with sickle cell disease result from the recent adoption of gene therapies and more rigorous supportive care standards. These interventions are helping to manage the chronic impacts of the condition more effectively than in previous decades.

Approximately 165 patients received gene therapy treatments in 2025, which carries high price tags including $2.2 million for exagamglogene autotemcel and $3.1 million for lovotibeglogene autotemcel.

The players

Washington University

This institution operates a clinical center that provides specialized hematology services and manages care for complex patient cases.

The details

Specialists are now prioritizing multidisciplinary services and proactive screening for organ damage to extend patient life. Additionally, care centers are hosting conferences for community-based hematologists to ensure that these sophisticated treatment standards are available across the country.

In the 1970s, life expectancy for sickle cell patients was less than 20 years.
2008 serves as the baseline year for current life expectancy measurements.
By 2022, half of all patients living with the disease were at least 60 years old at the time of death.
Gene therapy treatments were received by approximately 165 patients in 2025.

Market Landscape

The rising adoption of gene therapy marks a structural shift in the treatment of inherited blood disorders. This trend mirrors the trajectory established by the 2024 approval of exa-cel for beta-thalassemia, signaling a broader movement toward high-cost, curative genetic interventions.

While these therapies provide significant life-extending benefits, the high list prices of millions of dollars create financial hurdles for patients. Even with private insurance, individuals may face out-of-pocket costs reaching up to $40,000 for these specialized treatments.

The takeaway

The transformation of sickle cell disease from a condition with a short life expectancy to one manageable into the seventh decade of life illustrates the impact of focused investment in specialized care. Patients and providers should continue to monitor new research into compounds that increase fetal hemoglobin expression as a potential alternative to current high-cost therapies.
