Market Overview

The global Prader-Willi syndrome market involves the diagnosing, management, and treatment of Prader-Willi Syndrome. Prader-Willi syndrome is a rare genetic disorder that affects various parts of the body and primarily affects the child’s metabolism. Prader-Willi syndrome is an atypical hereditary condition that impacts the neurological, endocrine, and metabolic systems. Severe hypotonia, poor appetite, and feeding difficulties in early childhood are caused by the lack of expression of paternally inherited genes on the 15q11.2-q13 chromosome. This is typified by distinct facial features, strabismus, and musculoskeletal anomalies, and it leads to behavioral and intellectual problems as well as global developmental delays. About 25% of situations are caused by maternal uniparental disomy, whereas about 70% of cases are caused by abnormalities in genomic imprinting brought on by a paternal deletion. Infertility, genital hypoplasia, hypogonadism, and inadequate pubertal development are the hallmarks of the disease. The short stature and a certain behavioural trait are prevalent. Scoliosis, strabismus, and distinctive facial traits are frequently seen. Boys and girls from various ethnic origins are affected by the hereditary cause, which happens only by accident. Parents who have more than one kid with Prader-Willi syndrome are extremely uncommon. Human growth hormone is used as a treatment for children and is widely recommended by healthcare professionals in the management of Prader-Willi syndrome. Children with Prader-Willi syndrome frequently have trouble feeding because their muscles aren't as strong. Healthcare providers could suggest unique feeding techniques or high-calorie formulas to promote weight gain and track growth. Children and newborns with PWS can benefit from hormonal growth hormone (HGH) therapy in order to grow, increase muscular tone, and reduce body fat. Adults can also utilize it. A child's potential benefit from HGH and the associated hazards might be discussed with an endocrinologist. It has been demonstrated that GH therapy can improve mobility, reduce fat mass, raise height, lean body mass, and prevent behavioral issues. Speech and abstract reasoning are enhanced. Beginning in infancy or at the time of a PWS diagnosis, GH therapy is usually administered at 20% to 25% of the prescribed dosage into maturity.

Several government initiatives drive the market growth. For instance, the Indian government has reviewed its National Policy for Treatment of Rare Diseases, which has been kept in abeyance until the revised policy is issued or until further orders are issued. A component for the treatment of specified rare diseases, amenable to one-time treatment, has been included under the Umbrella Scheme of Rashtriya Arogya Nidhi, providing one-time financial assistance up to Rs.15 lakh to patients living below the threshold poverty line and taking treatment in Government Hospitals. The Minister of Health and Family Welfare, analysed the number of cases of Prader-Willi syndrome reported in India, the steps taken by the government to provide treatment, and whether there are Group Homes or similar facilities to provide specialized care and supervision. Therefore, such government initiatives provide awareness of rare diseases among the worldwide population and increase the demand for the therapeutic drugs used in the management of Prader-Willi syndrome and resulting in to market growth.

Driving Factors:

Increasing prevalence of Prader-Willi syndrome:

Globally, the prevalence of Prader-Willi syndrome is rising, which facilitates the awareness of this disorder and its medications used in the treatment and escalates the demand for the drugs used in this syndrome, resulting in the expansion of the Prader-Willi syndrome market. Individuals have a loss of functions of the gene in a specific region of the chromosome. As per the literature review, the Prader-Willi syndrome is mostly caused by the escape or deletion of chromosome 15 in each cell. For example, as per the data provided by the National Library of Science, the cases of Prader-Willi syndrome are increasing, and it is about to found 1 in every 20,00 to 30,000 births. Globally, 400,000 individuals are estimated with Prader-Willi syndrome, and 20,000 individuals in the United States.

Proliferation in innovations and advancements in gene therapy and targeted treatments:

The field of medicine is changing as a result of major developments in gene therapy and targeted therapies. The precise DNA editing tool known as CRISPR gene editing has been authorized for use in the treatment of sickle cell disease and other illnesses. Therapeutic proteins can be produced using mRNA technology, which is based on mRNA vaccines, without changing DNA. The autoimmune conditions lupus and multiple sclerosis are now being treated with CAR-T cell therapy, which was first created for cancer. Gold nanoparticles are becoming a more scalable and non-invasive substitute for conventional techniques. Monoclonal antibodies, TKIs, and antibody-drug conjugates are examples of targeted therapies. In an attempt to improve outcomes for diseases like ovarian cancer, personalized medicine platforms such as ChemoID are customizing treatments according to each patient's unique tumor profile. These developments are changing the medical landscape and driving market growth.

Restraining Factors

The limited awareness and knowledge of the Prader-Willi syndrome and its treatment in low-middle-income countries, the high cost of the medications, and the stringent guidelines framework for the approval of the drugs may impede the market growth.
