Egetis Therapeutics receives FDA Fast Track Designation for Emcitate® for MCT8 deficiency

October 8, 2021

Egetis Therapeutics AB (publ) (ticker: EGTX) today announced that the U.S. Food and Drug Administration (FDA) has granted the company’s lead candidate drug Emcitate®, currently in a pivotal study, Fast Track Designation for the treatment of the rare genetic disease MCT8 deficiency.

The FDA's Fast Track process is designed to facilitate the development and expedite the review of new drugs intended to treat serious or life-threatening conditions to address an unmet medical need with the purpose of getting important new drugs to the patient earlier. Fast Track designation provides a company early and more frequent communication with the FDA to improve the efficiency of the investigational drug’s development and provides eligibility for priority review if certain criteria are met.

“This Fast Track Designation is an acknowledgement from the FDA of the importance of Emcitate to address the significant unmet medical need in MCT8 deficiency and ultimately help these patients that suffer from this rare and devastating disease. These patients are currently left without any treatment options. With a Fast Track designation come opportunities to expedite both the NDA submission and FDA’s review which can enable Emcitate’s regulatory approval sooner” said Nicklas Westerholm, CEO of Egetis Therapeutics.

A first clinical trial in patients suffering from MCT8 deficiency of all ages has been concluded with significant and clinically relevant results. A pivotal clinical trial looking at early intervention in very young MCT8 deficient children is under way. Recruitment is expected to be completed in Q4 2021. Emcitate has been granted Orphan Drug Designation in the US and EU. Emcitate was also granted US Rare Pediatric Disease Designation in November 2020, eligible to apply for a Priority Review Voucher.

The information was submitted for publication, through the agency of the contact person set out above, at 2021-10-08, 08:00 CET.

About MCT8 Deficiency

MCT8 deficiency is a rare genetic disease with high unmet medical need and no available treatment, affecting 1:70,000 males. Thyroid hormone is crucial for the development and metabolic state of virtually all tissues. Thyroid hormone transport across the plasma membrane is required for the hormone’s metabolism and intracellular action and is facilitated by thyroid hormone transporters, including monocarboxylate transporter 8 (MCT8). Mutations in the gene for MCT8, located at the X-chromosome, cause MCT8 deficiency, also called Allan-Herndon-Dudley syndrome (AHDS) in affected males. The resulting dysfunction of MCT8 leads to impaired transport of thyroid hormone into certain cells and across the blood-brain-barrier and disruption of normal thyroid hormone regulation. This leads to a complex pattern of symptoms with neurological developmental delay and intellectual disability, accompanied by severely elevated circulating thyroid hormone concentrations which are toxic for tissues including the heart, muscle, liver and kidney and results in symptoms such as failure to thrive, cardiovascular stress, insomnia and muscle wasting. Most patients will never develop the ability to walk or even sit independently. At present there is no approved therapy available for the treatment of MCT8 deficiency.
