Moreover, limited availability of specialized treatments in retail or online pharmacies reinforces hospitals as the primary procurement and distribution hub.

Key Growth Drivers

Increasing Prevalence of Underlying Risk Conditions

Growing incidence of systemic and ocular conditions notably diabetes mellitus, viral infections (e.g., herpes simplex and herpes zoster), and corneal nerve trauma from surgery or contact-lens misuse has driven rising cases of Neurotrophic Keratitis (NK). As more patients experience corneal nerve damage, demand for effective NK therapies escalates. This trend expands the addressable patient pool and pushes healthcare providers to adopt specialized treatments, boosting overall market growth.

• For instance,Dompé Farmaceutici reported positive real-world data showing improved corneal healing in patients using their nerve growth factor–based therapy.

Emergence of Innovative Biologic and Regenerative Therapies

Advancements in biologic and regenerative medicine particularly therapies based on nerve growth factors and wound-healing agents have transformed NK treatment. These novel therapies target the underlying nerve-damage pathology rather than only managing symptoms, improving clinical outcomes and patient quality of life. As regulatory approvals and clinical evidence accumulate, adoption of these advanced treatments increases, reinforcing market expansion.

• For instance, Dompé Pharmaceuticals developed Cenegermin (Oxervate®), the first FDA- and EMA-approved recombinant nerve growth factor (rhNGF) eye drop treatment for NK, shown to improve corneal nerve density and visual acuity through multiple clinical trials involving over 200 patients.

Growing Clinical Awareness and Improved Diagnostics

Enhanced understanding of NK among ophthalmologists and broader awareness among patients have improved early detection and proper diagnosis. Improvements in diagnostic protocols including sensitivity testing and clinical staging enable timely intervention before severe corneal damage occurs. As a result, rates of diagnosed and treated cases increase, creating greater demand for approved therapies and expanding the overall market.

Key Trends & Opportunities

Rising R&D and Pipeline Expansion for Novel Therapies

Pharmaceutical companies and biotech firms are intensifying research into new therapeutic options for NK, including next-generation growth-factor formulations, regenerative agents, and innovative delivery systems. This trend creates opportunities for development of more effective, safer, and patient-friendly treatments, which can potentially improve access and adherence especially in markets where current options are limited or expensive.

• For instance, Gamida Cell employs a proprietary nicotinamide (NAM) cell expansion platform to enhance NK cell potency, function, and persistence, with positive Phase 1 clinical data for GDA-201 and planned Phase 1/2 studies for cryopreserved versions targeting hematologic malignancies.

Increased Emphasis on Early Diagnosis and Preventive Ophthalmic Care

Healthcare providers and public-health stakeholders are placing greater emphasis on early ophthalmic screening - especially among high-risk populations (e.g., diabetics, post-corneal surgery patients, recurrent herpes keratitis sufferers). This focus on preventive eye care raises detection rates of subclinical or early-stage NK, enabling earlier intervention. As a result, demand for accessible therapies and maintenance treatments increases, widening market reach.

• For instance, BRIM Biotechnology received FDA orphan drug designation for BRM424, a novel regenerative therapy aimed at stimulating corneal limbal stem cells to accelerate healing in NK patients.

Key Challenges

High Treatment Costs and Limited Accessibility in Emerging Markets

Many advanced NK therapies, such as recombinant nerve growth factor drops, autologous serum eye-drops, and biologic wound-healing agents, are expensive, significantly limiting their affordability and widespread adoption, particularly in low- and middle-income regions. These high-cost treatments create a significant barrier to access, restricting their penetration into large patient pools and hindering their adoption in underserved markets. As a result, only a small percentage of patients benefit from these advanced therapies, which may dampen overall market growth. Furthermore, the disparity in access to these treatments exacerbates the treatment gap, especially in countries with limited healthcare budgets or inadequate insurance coverage.

Rare Disease Status and Low Patient Volume Hamper Market Scale-up

As a rare disease, NK affects a relatively small population globally (prevalence < 5 per 10,000 in some regions), which significantly constrains the potential patient base. This small volume makes it less attractive for some pharmaceutical companies to invest heavily in large-scale production or aggressive outreach, slowing the pace of new treatment introductions and limiting broader market expansion. The limited market potential in terms of patient numbers further discourages large investments in clinical trials and distribution networks, resulting in slower adoption of new therapies. Additionally, the low awareness among both healthcare providers and patients contributes to the underdiagnosis and under-treatment of the disease, further restricting the market’s growth opportunities.
