Orphan Diseases Market Size

Global Orphan Diseases Market Overview 

Orphan Diseases Market Size was valued at USD 193.95 Billion in 2023. The Global Orphan Diseases industry is projected to grow from USD 214.7 Billion in 2024 to USD 484.18 Billion by 2032, exhibiting a compound annual growth rate (CAGR) of 11.20% during the forecast period (2024 - 2032).

Orphan diseases are also popularly called rare diseases. The market for the orphan disease is growing rapidly in the forecast period. This disease affects a small percentage of the population across the World. Research says that most orphan diseases remain with the patient throughout life as it is genetic. The exact number of diseases are not found yet, but there are nearly more than 7000 various rare disorders and diseases are present across the World. 

The increasing patient population with a rare disease contributes to the global market throughout the review period. Moreover, the research and development initiatives are increasing day by day, fuelling the worldwide market growth. Also, the increasing adoption of orphan drugs is enhancing the market growth. 

According to the Orphan Diseases Market Trends report, the current market has some intended audiences who contribute to generating more scope and opportunities for the global market. These intended audiences are hospitals and clinics, medical research laboratories, orphan diseases drug manufacturers and suppliers, potential investors, government and independent regulatory authorities, market research and consulting service providers, and research and development (R&D) companies. 

Rare diseases accounted for half of the US Food and Drug Administration’s (FDA) approvals in January 2024, with most having fast-track designations leading to compressed time-to-market and increasingly competitive smaller-patient-population markets. Organizations need to embark on their project journeys at least 24-36 months before approval so as to fully understand the patient journey, effectively educate providers, foster advocacy, and get a clear path from diagnosis through treatment access. The early alignment to cross-functional strategy helps in making decisions about what should be prioritized and resources pre-approval used more judiciously.

Barely a year after it became a commercial biotech firm, Krystal Biotech is aiming high with its lead product. In May 2023, Krystal made history when Vyjuvek was approved by the FDA for treating dystrophic epidermolysis bullosa (DEB), a rare skin disorder, becoming the first ever skin-based gene therapy and the first-ever drug based on herpes simplex type 1 virus receiving such an approval. This topical gel contains genetically modified herpes simplex virus type I that is applied directly onto DEB lesions, thus delivering copies of the COL7A1 gene into them. Any touch causes tearing or blistering of these patients’ highly fragile skin, which results in open wounds that are prone to fibrosis and infections.

In October 2023, NORD® launched an English/Spanish educational series called “Rare Disease Drug Development: What Patients and Advocates Need to Know” in order to enable patients as well as disease-specific advocacy groups who are often unfamiliar with the development process of drugs. The modules come in varied formats like animated videos, expert interviews, infographics, fact sheets, checklists, or interactive quizzes catering to various learning styles among users.

India’s AstraZeneca entered into rare disease therapy in March 2023. The regulatory approval of its ‘Selumetinib’ demonstrates the company’s commitment to bring first-in-class, science-based therapies to patients in India. In addition, it is expected that the company will be able to address the major unmet needs of these patients who have rare diseases and transform their quality of life going forward. It was after acquiring Alexion in 2021 that AstraZeneca embarked on expanding its rare disease portfolio globally to include innovative therapies for Indian people with rare ailments.
