CAN GENE THERAPY AND RNA TECHNOLOGY COMBAT CYSTIC FIBROSIS?

07 Feb CAN GENE THERAPY AND RNA TECHNOLOGY COMBAT CYSTIC FIBROSIS?

Cystic Fibrosis is a chronic genetic disorder of the mucus glands that affects 2,500 newborns each year in the U.S.  30,000 people are currently affected by this disease and about 1 in 20 or roughly 12 million Americans are carriers of the “CF” gene and are unaware of their condition according to the Centers for Disease Control and Prevention.

There is no permanent treatment for this condition. Efforts are limited to alleviating the symptoms and slowing down the progression of the disease, which has resulted in an increase in the lifespan of the affected to 30 years from being nearly fatal.

The treatment for cystic fibrosis mainly consists of reducing the mucus blockage of the lungs by physical therapy (postural, bronchial drainage), exercise and therapeutics. Medicinal options usually consist of aerosolized bronchodilators, CFTR Modulators, Pancreatic enzyme supplements, mucolytics and decongestants.

Ongoing research in the field is trying to address the unmet needs for a long-term and safe solution for tackling this disease. Companies are creating breakthrough technological innovations such as Gene therapy, rectifying the chloride transport defect in cells, improving diagnostic tools, etc.

There is a huge potential for growth in the cystic fibrosis treatment market which is indicated by the projection that the industry will be worth USD 13.9 billion by 2025, according to a research report by Grand View Research, Inc.

The market will see tremendous progress in the future owing to innovations by companies such as gene therapy, RNA technology, Protein targeting and novel administration methods.
