The Duchenne Muscular Dystrophy Market Size (DMD Market) in the 7MM was found to be USD 266.06 Million in 2017, during the study period (2017-2030).
A rare muscle disorder, Duchenne Muscular Dystrophy (DMD), approximately affects 1 in 3,500 male births globally. Moreover, Duchenne Muscular Dystrophy prevalence in the 7MM (The US, EU5, and Japan) was found to be approximately 31,386 in 2017 with the diagnosed prevalence of 26,678.
Duchenne Muscular Dystrophy is an X-linked genetic disorder caused by a mutated gene on the X-chromosome, hence the reason why it mostly manifests in males. Females with the defective gene become the carriers hence passing the gene forward to next generation. The mutation in the DMD gene which is responsible for transcribing into a protein called dystrophin, which plays an essential role in maintaining the integrity of cell membrane in skeletal (voluntary) and cardiac muscle cells. Absence of protein, over time, leads to degeneration of muscle fibres, a progressive weakening of muscles and is known to affect communication, and socio-emotional skills as well. Shockingly, by the age children turn 13, they become dependent on wheelchairs.
Duchenne Muscular Dystrophy Market: Unmet needs and hope for a cure
For such a disabling disease, the goal of the treatment of the disease until now remains symptomatic in nature by managing the associated complication and maximize the quality of life.
Several forms of therapies such as Corticosteroids, Steroids, Assistive devices, Physical therapies, and others are available in the market that helps in alleviating the symptoms. Corticosteroids, so far, have remained the standard treatment and help in strengthening muscles and improving ling function. Assistive devices help the patients with breathing difficulties, on the other hand, Orthopedic devices help in facilitating the movements of the patients. Steroids have also proven to be beneficial in extending the ability of the patient to walk by 2-5 years; however, use of steroids can result in side effects such as weight gain, high blood pressure, behavior changes, and delayed growth. Some of the available steroids in the Duchenne Muscular Dystrophy Market are Prednisone, Deflazacort, and Oxandrolone. Some of the medications that have been granted orphan drug status are
Deflazacort, manufactured by PTC Therapeutics/Marketed by Marathon Pharmaceuticals is FDA-approved treatment for Duchenne Muscular Dystrophy in patients 5 years of age and older. Whereas, Eteplirsen, manufactured by Sarepta Therapeutics, is approved for the treatment of DMD in patients who have a confirmed mutation of the DMD gene that is amenable to exon 51 skipping.
In addition to Deflazacort and Eteplirsen, Ataluren is another drug approved within the European Union (EU), Iceland, Liechtenstein, Norway, Israel, and South Korea for nmDMD in ambulatory patients aged two years and older.
However, the current Duchenne Muscular Dystrophy Market is evaluating the potential of the genetically engineered therapies to be incorporated into DMD pipeline that include exon skipping, use of recombinant adeno-associated virus carrying mini-dystrophin, and surrogate gene transfer. Moreover, extensive research is underway tracking the role of palliative care in improving the course of the disease during adolescence and beyond.
At present, it is one of the major unmet needs and calls for a proper understanding of the concept of adolescence and neuromuscular conditions as the Duchenne Muscular Dystrophy prevalence keeps on rising. Furthermore, the challenges that obstruct the successful delivery of gene therapies such as the product gene size, the origin of dystrophin gene expression, transport effectiveness, and immunological rejection needs to be addressed to tackle the burden DMD is posing.
To address various such prevailing unmet needs in the Duchenne Muscular Dystrophy Market, several randomized trials are being conducted by pharma and biotech companies that are currently researching new drugs with novel mechanisms of action such as drugs with a high-efficacy/toxicity ratio to improve outcomes in DMD. Companies, like Sarepta Therapeutics (Casimersen [SRP-4045]), Santhera Pharmaceuticals (Idebenone), Catabasis Pharmaceuticals (Edasalonexent), Hoffmann-La Roche (Talditercept alfa), FibroGen (Pamrevlumab, Capricor (CAP-1002), Antisense Therapeutics (ATL1102) and ReveraGen BiPharma (Vamorolone), Italfarmaco (Givinostat), Nobelpharma (Arbekacin), Pfizer (PF-06939926), Cumberland Pharma (Ifetroban) and many others are working toward to accelerate the Duchenne Muscular Dystrophy Market.
Some of the companies have recently found the DMD market prosperous enough to invest their time and money in it; however, others have long been working to advance the DMD treatment market and find a standard cure for the disease. In addition to ongoing research activities and a rich Duchenne Muscular Dystrophy pipeline, an increasing proportion of the disease among adolescents would also influence the Duchenne Muscular Dystrophy Market during the forecast period.
