MoCoD-A Drug Pipeline: What’s Next in Rare Metabolic Disorders

Molybdenum Cofactor Deficiency Type-A (MoCoD-A) is an ultra-rare, life-threatening metabolic disorder characterized by rapid and progressive neurological deterioration. Patients typically exhibit symptoms such as severe seizures, impaired autonomic function, muscle tone abnormalities, feeding difficulties, and distinct facial features early in life. The root cause of MoCoD-A is a deficiency in sulfite oxidase, one of the molybdenum-dependent enzymes in humans. This enzyme loss results in toxic accumulation of sulfite, contributing to irreversible neurological damage and often early mortality.

Epidemiology of MoCoD-A Across the 7MM

The epidemiological assessment of MoCoD-A in the 7MM—which includes the United States, EU4 (Germany, France, Italy, Spain), the United Kingdom, and Japan—captures key indicators such as prevalent cases, diagnosed prevalence, and type-specific segmentation. In 2023, approximately 270 diagnosed prevalent cases were reported in total. The United States led with an estimated 30 cases, with projections indicating gradual growth due to increasing disease awareness and diagnostic advancements. Meanwhile, the EU4 and the UK combined had about 20 diagnosed cases, with Spain recording the fewest among them. Japan, accounting for 9% of total cases, is also expected to witness a notable rise in diagnosed cases by 2034.

Market Landscape and Challenges

The total MoCoD-A market size across the 7MM was estimated at USD 12.20 million in 2023, a reflection of both the rarity of the disease and the lack of available treatments. Although research interest is slowly increasing, several challenges hinder the market’s expansion. The rarity of the condition means there is limited awareness among both healthcare professionals and the general public. As a result, many cases go undiagnosed or are identified late, significantly reducing the chances for timely intervention.

Current Treatments and Key Players

At present, Nulibry (fosdenopterin) by BridgeBio Pharma stands as the first and only FDA-approved therapy for MoCoD-A. However, therapeutic options remain extremely limited, and access to treatment is often complicated by the high costs and complexity of genetic testing required for diagnosis. In many cases, this lack of early detection hampers effective disease management. Moreover, the absence of broader treatment options highlights the critical need for continued research and investment in rare disease therapeutics. With BridgeBio Pharma as a leading player, further development is anticipated in the coming years.
