For instance, on September 11, 2024, Agios Pharmaceuticals, Inc., a frontrunner in cellular metabolism and PK activation dedicated to developing therapies for rare diseases, announced that the U.S. Food and Drug Administration (FDA) has awarded orphan drug designation to its innovative pyruvate kinase (PK) activator, tebapivat (AG-946), intended for the treatment of myelodysplastic syndromes (MDS).

Rising Prevalence of Rare Diseases Fueling Demand for Orphan Drugs

The rising incidence of rare diseases in the United States has markedly increased the demand for orphan drugs. The National Institutes of Health (NIH) reports that around 7,000 rare diseases impact more than 30 million Americans. Many of these conditions lack adequate treatment options, leading to a significant unmet need for specialized therapeutics. Orphan drugs are designed specifically for these diseases, and their market has expanded due to heightened awareness, earlier diagnoses, and advancements in genetic testing. Additionally, the U.S. Food and Drug Administration (FDA) has introduced various incentives, including tax credits, market exclusivity, and accelerated approval processes, to promote the development of orphan drugs. These measures have led to a rise in research and development investments from pharmaceutical companies. For instance, in February 2024, Amgen received FDA approval for BLINCYTO (blinatumomab), an orphan drug for the treatment of minimal residual disease (MRD) in acute lymphoblastic leukemia (ALL) patients. This approval not only adds to Amgen’s oncology pipeline but also highlights the industry’s growing commitment to addressing rare disease burdens.

Government Incentives and Regulatory Support Accelerate Orphan Drug Approvals

The proactive regulatory framework established by the U.S. government significantly drives the orphan drug market. The Orphan Drug Act of 1983 provided essential regulatory and financial incentives, including seven years of market exclusivity, research grants, and tax credits for clinical trials. These advantages motivate biotech and pharmaceutical companies to pursue the development of treatments for rare diseases, even with limited patient populations. The FDA’s Office of Orphan Products Development (OOPD) is instrumental in accelerating these therapies' review and approval processes through initiatives such as Fast Track, Breakthrough Therapy, and Priority Review designations. In recent years, this supportive environment has resulted in a notable increase in orphan drug designations and approvals. A notable example is when Acadia Pharmaceuticals Inc. had declared in the U.S. in March 2023, that the U.S. Food and Drug Administration (FDA) had approved DAYBU (trofinetide) to treat Rett syndrome in both adult and pediatric patients aged two years and older. DAYBUE is the sole medication authorized to treat Rett syndrome. The approval underlines how streamlined pathways and strong regulatory backing are helping more orphan drugs reach patients faster, boosting innovation and accessibility in the U.S. market.

Oncology Segment Dominates with Increasing Development of Rare Cancer Therapies

Oncology represents the largest U.S. orphan drugs market segment among various therapeutic areas. The increasing prevalence of rare cancers, including soft tissue sarcomas, gliomas, and specific blood malignancies, has notably heightened the demand for specialized treatment options. Pharmaceutical firms are sharpening their focus on developing targeted therapies and immuno-oncology medications that provide enhanced effectiveness and reduced side effects compared to traditional treatments. The robust presence of biotechnology companies, investments in precision medicine, and a growing pipeline of clinical trials in the U.S. further bolstered this sector's growth. Additionally, the orphan drug designation for oncology products frequently results in expedited regulatory approvals, lower development expenses, and prolonged market exclusivity, rendering it a highly profitable domain. For instance, in August 2023, Bristol Myers Squibb received FDA approval for REBLOZYL (luspatercept-aamt) as a first-line treatment for anemia in adults with lower-risk myelodysplastic syndromes, which includes certain rare cancers. This approval under the Orphan Drug Act highlights the market’s strong momentum in rare oncology therapeutics.
