Can gene therapy forge a better future for rare diseases? A perspective on rare disease day

In recognition of Rare Disease Day, let’s put a spotlight on the transformative potential of gene therapy in clinical practice, and the critical role of accurate information in empowering clinicians to advance health equity for these unique patient populations.

The uncommon commonality of rare diseases

While each rare disease may affect a relatively small population – fewer than 1 in 2,000 individuals¹ – the collective impact is profound. Over 7,000¹ distinct rare diseases impact more than 300 million people globally², and new conditions are continually being identified as research advances. With 80% of rare diseases rooted in genetics³ and 95% lacking an FDA approved treatment⁴, the pursuit of equitable access to diagnosis, care, and treatment is more crucial than ever.

The dawn of gene therapy: a beacon of hope

After decades of research, gene therapy offers tremendous hope for rare diseases, and the treatment is becoming a reality in clinical practice. The FDA has approved a number of gene therapies, including 7 in 2023⁵, and many more are in clinical trial stage, building further future promise. Gene therapy treatment works by altering the genetic code to recover the functions of critical proteins.

Advancements in neuromuscular disease treatment

Neuromuscular diseases (NMDs) have seen significant therapeutic advancements, including two FDA-approved gene therapies that each target diseases affecting under 200,000 US individuals⁶.

These therapies, Onasemnogene abeparvovecxioi (Zolgensma; Novartis) and SRP-9001 minidystrophin (Elevidys; Sarepta Therapeutics), exemplify the progress in NMD treatment. The former was approved to treat children younger than 2 years with a confirmed diagnosis of spinal muscular atrophy (SMA)⁶, and the latter received accelerated approval to treat ambulatory children aged 4 to 5 years with Duchenne muscular dystrophy (DMD)⁷. As we celebrate Rare Disease Day 2024, there are currently a number of clinical trials for NMD gene therapy that are active or recruiting, demonstrating encouraging progress for the development and advancement of gene therapies in the NMD space.

Navigating the challenges of cost

The path to developing treatments for rare diseases is fraught with financial challenges. The high upfront costs of gene therapy, coupled with the limited patient population for each disease, complicate the sustainability of such treatments.

There is still work to be done to reduce these burdens and improve treatment access, but there are government policies that are stimulating research and development of new therapies, as well as access to medicines. The Orphan Drug Act in the US helps incentivize gene therapy development, and in the UK, the Early Access to Medicines Scheme (EAMS) has benefitted rare diseases patients living with Duchenne muscular dystrophy for earlier access to life-changing treatments.

Empowering clinicians with knowledge and tools

At the recent 2024 Fair Pricing Forum, the World Health Organization put a spotlight on recent advances for rare disease treatment, but also highlighted the ongoing need for infrastructure investment and the need to better prepare health systems with the significant skills required.

Medical expertise for each rare disease is a scarce resource, so education and access to comprehensive clinical resources are indispensable. The UK Framework for Rare Disease emphasizes the importance of raising awareness among healthcare professionals, fostering an environment where rare diseases are considered and accurately diagnosed.
