Key Market Drivers

Rising Number of Patients with Rare Diseases

There are a lot of rare diseases in the medical world. Some are well-known, like cystic fibrosis or cat eye syndrome, while others are more obscure. Most cancers are rare and there are rare diseases of the brain and nervous system, metabolic diseases, chromosome disorders, skin, bone and skeletal, and diseases that affect the heart, blood vessels, lungs, kidneys and other organs and systems. A lot of rare diseases are named after the doctors who first diagnosed them, while others are named after patients or even the hospitals where they were first diagnosed.

According to the Indian Organization for Rare Diseases, nearly 7,000 rare diseases have been identified to date, the majority of which lack targeted treatment options. Supporting this, a 2020 report by the World Economic Forum highlights that approved therapies exist for only around 5% of these conditions, underscoring a substantial unmet medical need across the rare disease landscape.

In Europe, rare diseases collectively impact an estimated 6% to 8% of the population translating to approximately 30 million individuals. However, despite this substantial figure, each rare disease affects only a small fraction of the population, leading to what is often referred to as the "rarity paradox." This paradox highlights the disconnect between the collective significance of rare diseases and the minimal attention given to each individual condition. Because of their low prevalence, these diseases frequently receive limited research funding, reduced clinical focus, and inadequate pharmaceutical investment, resulting in delayed diagnoses, insufficient treatment options, and a general lack of awareness among healthcare professionals and policymakers. This systemic underrepresentation underscores the need for more coordinated policy efforts, cross-border collaborations, and incentivized R\&D to bridge the gap in therapeutic development and improve outcomes for the millions of patients affected across the region.

Initiatives taken by Government and Market Players

The global rare disease therapeutics market is witnessing robust growth, significantly propelled by strategic initiatives from both government bodies and private sector stakeholders. These interventions aim to address the chronic underrepresentation, funding limitations, and limited treatment availability that have historically plagued the rare disease landscape. Governments across North America, Europe, and Asia-Pacific have implemented specialized frameworks such as the U.S. Orphan Drug Act (1983), the EU Orphan Regulation (2000), and Japan’s Orphan Drug Designation system. These policies offer a variety of incentives including tax credits, fee waivers, market exclusivity (7–10 years), and expedited review processes. Such incentives lower the entry barriers for pharmaceutical companies, reduce R&D risks, and accelerate time-to-market for new therapies. The Indian government, through the National Policy for Rare Diseases (NPRD) 2021, has implemented a targeted funding mechanism to support both patient treatment and research advancement. Under this policy, eligible patients undergoing treatment at designated Centers of Excellence (CoEs) are entitled to financial assistance of up to ₹50 lakh. This initiative not only improves access to high-cost therapies but also strategically strengthens institutional capacity for rare disease management and clinical research across approved centers. Many countries are formulating comprehensive national strategies to improve diagnosis, treatment access, and patient support systems. The creation of rare disease registries and databases facilitates epidemiological tracking, clinical trial recruitment, and long-term patient outcome monitoring, thus encouraging evidence-based innovation and investment.

Leading biopharmaceutical companies are increasingly prioritizing rare diseases due to their high unmet need and the potential for premium pricing. Firms like Roche, Novartis, Takeda, and Alexion (AstraZeneca) have made rare diseases a core part of their growth strategy, with a focus on biologics, gene therapies, and precision medicine. To accelerate innovation and reduce time-to-market, companies are entering strategic alliances with biotech firms, research institutions, and patient advocacy groups. These partnerships help in accessing proprietary technologies, biomarkers, and rare patient populations. For instance, larger firms often collaborate with academic centers to leverage genomic research and early-stage discovery assets. Given the high cost and complexity of rare disease treatments, companies are adopting innovative pricing models, outcome-based reimbursement strategies, and expanded access programs. These efforts are designed to improve treatment affordability and adherence, while also aligning stakeholders around value-based care. Government support for advanced therapy medicinal products (ATMPs), including gene and cell therapies, combined with industry-driven innovation, has redefined treatment paradigms for many previously untreatable conditions. Technologies such as CRISPR-based gene editing, RNA therapeutics, and AI-enabled drug discovery platforms are accelerating therapeutic development, enhancing precision, and reducing development timelines.

Growing Burden of CNS disorders can Drive the Development of Precision Treatments for Rare Diseases 

As the incidence and prevalence of rare diseases in the central nervous system (CNS) increase, there is an amplified need to gain a better understanding of the genetic, molecular, and biochemical substrates of these diseases. Genetics and neuroscience have enabled researchers to gain a greater understanding of the complexities of rare CNS disorders, allowing for the identification of disease-inducing mutations and pathways. Neurological disorders have emerged as the foremost contributor to the global burden of disease, impacting approximately 43% of the global population equivalent to 3.4 billion individuals. These conditions are responsible for an estimated 443 million disability-adjusted life years (DALYs) lost, exceeding the impact of cardiovascular diseases and underscoring the urgent need for targeted therapeutic interventions and healthcare system prioritization.

Rare disease treatment market value from the central nervous system is expected to accelerate in the forecast period, given the rising prevalence of disorders that affect nerve cells in the spinal cord and brain, causing loss of muscle control. Amyotrophic lateral sclerosis (ALS) is classified as a rare neurodegenerative disorder, with a global prevalence of approximately 4 to 6 cases per 100,000 individuals. Notably, the prevalence rate exceeds the annual incidence, indicating that advances in disease management and supportive care are contributing to longer survival times for patients already diagnosed, despite the absence of a curative treatment. Precision medicine is a form of medical treatment that is tailored to the unique needs of each individual patient, considering factors such as genetics, lifestyle, and environment. In rare diseases of the central nervous system (CNS), where each condition is caused by a distinct genetic mutation, targeted therapies are becoming increasingly feasible. Understanding the genetic makeup of a patient’s disorder allows clinicians to design targeted therapies that address specific molecular defects.

Precision medicine is heavily reliant on biomarkers. These are things that can be measured to show the presence or progress of a disease. Developing precision treatments for rare diseases of the central nervous system often involves finding and testing biomarkers related to certain disorders. These biomarkers can help early diagnosis, track disease progress, and measure how well treatment is working. As treatment options for rare CNS diseases are limited, precision medicine approaches involve examining the potential of drugs that have been developed for other conditions to treat a rare disease. By elucidating the molecular pathways associated with both the rare condition and other common conditions, researchers may be able to identify drugs that could potentially treat the rare CNS disorder.

The prevalence of rare diseases in the central nervous system (CNS) has prompted researchers and pharmaceutical manufacturers to pay greater attention to these conditions. The development of precision medicine techniques has made it simpler to conduct specific research on rare diseases, thus accelerating the development of drugs and overall market growth.

Key Market Challenges

Accurate Diagnosis

Finding a diagnosis is the key to successful treatment and, in some cases, clinical trial involvement. However, accurate and timely diagnosis of a rare condition can be challenging for patients and in some cases an accurate diagnosis may take up to five years.

In rare cases, patients may present signs and symptoms that a medical professional may not be able to identify as being related to or caused by the disease. In such cases, extensive genetic testing may be conducted to identify genetic variations that may be associated with the manifestation of the disease. It is always beneficial to ensure that the patient is either assigned to a clinical geneticist or/or a physician who is familiar with the difficulties associated with interpreting genetic data.

Patient Availability and Recruitment

Recruiting patients to participate in clinical trials in the field of orphan medicinal products is a challenging task. Not only is it challenging to determine the target patient population, but also finding investigators who specialize in treating these patients is challenging. These difficulties may pose a recruitment risk and necessitate a customized feasibility approach to reduce risk for each rare disease study.

Because the patient population is likely to be geographically distributed, patients may be required to travel considerable distances to access the study site for an orphan disease clinical trial. While travel reimbursement could potentially reduce this risk, organizations should also explore novel solutions and technologies to collect data from home and minimize site visits.

Endpoint Selection

When designing therapeutics for rare conditions, it is important to ensure that clinical study endpoints measure how the drug changes the progression of patient's disease. To distinguish a drug effect from standard disease progression, clinical studies and endpoint design must adequately reflect regulatory requirements and payer considerations.

It is recommended that sponsors collaborate with regulatory agencies to determine efficacy endpoints prior to the clinical study. The Food and Drug Administration organizes disease-specific forums to identify and discuss endpoints that are relevant from the patient or caregiver's point of view; these endpoints may include verified patient-reported outcomes that include the patient's voice. Rare disease often requires participation from numerous sites across many regions

Key Market Trends

Growing Product Innovation

Rising demand for rare diseases has led to the development of various therapies for the disease. For instance, in February 2023, Sanofi is planning to launch two of its medicines for rare diseases in India early this year or next year. The company has been recommended by the Subject Expert Committee for the import and placing on the market of the two novel products in India: Nexviazyme (Aveloglucosidase Alfa powder) for the treatment of Pompe disease and Xenpozyme and Olipudase Alfa powder, for the treatment of Niemann Pick disease (ASMD). According to a company note, both products have orphan drug status and are approved in several countries including the United States, Australia, the European Union, the United Kingdom, and Japan.

According to pharmaceutical trade organization  (PhRMA), more than 600 orphan drugs have received FDA approval since Orphan Drug Act’s inception, yet only 5 percent of rare conditions have an FDA-approved treatment, meaning there’s still plenty of untapped growth potential for years to come. For instance, in 2022, FDA announced the launch of the new Accelerating Rare Disease Cure (ARC) Program.

Companies Launching Initiative Programs

There are various initiatives being taken by companies to help people living with rare diseases. For instance, in 2022, Horizon launched new support initiatives for adults and teens living with rare disease. Being a rare disease sufferer can be challenging and lonely. To provide relief to the estimated 500-600 individuals living with cystic fibrosis in the United States, Horizon Therapeutic launched two distinct initiatives. Additionally in 2021, Horizon Therapeutics announced the launch of monthly virtual storytelling experience, #RAREis, to highlight the voices and stories of the community of children living with rare diseases and to raise awareness and funds for Make-A- Wish Mid-Atlantic and Make-A-Wish Canada. This photobooth is part of Horizon’s global mission to support the wishes of children living with life-altering rare diseases and to bring smiles to their faces during a difficult time. Further, in support for the rare disease community, Horizon’s U.S headquarters in Deerfield, Illinois and global headquarters in Dublin, Ireland was lit in purple, pink, green, and blue, the official colors of rare disease day.
