With the inflow of capital showing no signs of slowing, we can expect significant progress to be made in identifying targets and developing breakthrough treatments over the coming years.

Rising prevalence and diagnosis of rare kidney diseases

There are multiple factors that are contributing to a growth in prevalence and improved diagnosis of rare kidney diseases globally in recent times. Advances in modern medical technologies have enabled doctors to detect manifestations that were not identifiable before. Next generation sequencing has dramatically improved our ability to pinpoint causal genetic mutations underlying many rare conditions. This is leading to more conclusive diagnoses than ever before. Meanwhile, improved awareness among the healthcare community and public is resulting in enhanced screening efforts and improved identification of at-risk populations.

Higher rates of diagnosis are also a reflection of populations aging in many parts of the world. As lifespan increases, patients now survive long enough for rarer forms of kidney diseases to manifest later in their lifetime. Growing environmental pollutants and toxin exposures pose novel risks that can trigger atypical presentations of rare diseases as well. International travel and migration trends have made it more common for doctors to encounter patient cases originating from diverse ethnic backgrounds with a higher likelihood of certain rare genetic diseases.

Lastly, patients have become more proactive in self-advocating and pioneering the use of online communities to crowdsource information to arrive at the right diagnosis after “doctor shopping” for several years. While not all cases can be identified, the collective efforts of multiple parties are expanding our edges of medical understanding and narrowing the gap between estimated and confirmed prevalence of many under-recognized rare kidney conditions. This momentum will likely continue its positive impact.

Challenge: High cost of drug development

The high cost of drug development is a major challenge for the rare kidney diseases market. Developing drugs to treat rare diseases is very expensive due to the small patient populations and limited market size. This results in pharmaceutical companies lacking sufficient financial incentive to invest resources into researching and developing new treatments. With small target populations, rare disease drug developers are often unable to recoup their high investment costs through product sales alone.

It is estimated that developing an orphan drug can cost over $1 billion, while the average drug costs around $800 million to develop. Additionally, clinical trials for rare diseases are challenging due to difficulties finding enough patients to participate. This prolongs development timelines and increases costs further. The high financial risks associated with rare disease drug development may discourage companies from entering this market space. For the rare kidney diseases market to grow, mechanisms need to be established that make drug R&D more financially viable for pharmaceutical companies.

Opportunity: Expanding research collaborations

Expanding research collaborations between pharmaceutical companies, patient advocacy groups, and government agencies presents a major opportunity for growth in the rare kidney diseases market. By collaborating, the different stakeholders are able to pool their resources and expertise to advance drug development at a lower overall cost. For example, patient advocacy groups play an important role by assisting with patient recruitment for clinical trials.

They establish networks of potential participants and raise awareness of trial opportunities. Government agencies also offer funding support through public grants as well as incentives such as extended market exclusivity periods for orphan drugs upon approval. This helps boost the potential returns on investment for pharmaceutical developers and share some of the financial risk. Increased partnership between players in the rare disease space is therefore key going forward. It lowers barriers to rare disease drug development and fuels greater investment into new treatments and cures, expanding the rare kidney diseases market overall.

Key winning strategies adopted by key players of Rare Kidney Diseases Market

Focus on gene therapy and precision medicines: Many big pharmaceutical companies are investing heavily in developing gene therapies and precision/personalized medicines to treat rare kidney diseases. For example, Reata Pharmaceuticals' bardoxolone methyl showed promise in treating Alport syndrome and IgA nephropathy in Phase 2 trials. If approved, it could significantly help patients with limited treatment options. Vertex Pharmaceuticals acquired Exonics Therapeutics in 2021 to gain access to its pipeline of gene therapies for polycystic kidney disease (PKD) and Alport syndrome.
