Eidos Therapeutics Receives Positive Opinion for Orphan Designation from the European Medicines Agency for AG10, a Potent Oral Stabilizer for the Treatment of Transthyretin Amyloidosis

October 26, 2018 at 8:00 AM EDT

SAN FRANCISCO, Oct. 26, 2018 (GLOBE NEWSWIRE) -- Eidos Therapeutics, Inc. (Eidos) (Nasdaq:EIDX), announced today that the Committee for Orphan Medicinal Products (COMP) within the European Medicines Agency (EMA) adopted a positive opinion for the designation of Eidos’ product candidate, AG10, as an orphan medicinal product for the treatment of transthyretin (TTR) amyloidosis (ATTR). In addition, the EMA also granted a product-specific pediatric investigational plan waiver to Eidos for AG10.

TTR normally circulates as a four-part molecule or tetramer, but in ATTR the molecule dissociates into individual monomers, which are unstable and aggregate as amyloid fibrils. Eidos’ lead product candidate, AG10, is designed to target ATTR at its source by stabilizing tetrameric TTR in the blood.

“We are pleased to have received Orphan Drug Designation from the FDA and now a positive opinion from the EMA as well. Eidos is excited about the opportunity to work with the ATTR patient and provider community on the further development of AG10 for ATTR,” noted Jonathan Fox, M.D., Ph.D., president and chief medical officer of Eidos. “Importantly, AG10 has demonstrated potent stabilization of tetrameric TTR in our clinical program, and we believe maximizing the level of TTR stabilization will lead to optimal clinical benefit for patients living with this devastating disease.”

Orphan Designation by the European Commission provides regulatory and financial incentives for the development of medicines that treat a life-threatening or chronically debilitating condition affecting less than five in 10,000 people in the European Union (EU). Orphan Designation provides Eidos with certain benefits, including EU market exclusivity upon regulatory approval, if received, reductions in EMA application fees, and access to protocol assistance. Eidos is pursuing AG10 for the treatment of ATTR cardiomyopathy (ATTR-CM) and ATTR polyneuropathy (ATTR-PN), both of which are progressive, fatal diseases. The company plans to initiate Phase 3 studies in each indication in the first half of 2019.

About AG10

AG10 is an investigational, orally administered small molecule designed to potently stabilize tetrameric transthyretin, or TTR, thereby halting at its outset the series of molecular events that give rise to amyloidosis, or ATTR. AG10 is currently being examined in a Phase 2 clinical trial in patients with ATTR cardiomyopathy and symptomatic heart failure. Results from this trial will be presented on November 10, 2018 at the American Heart Association’s Annual Scientific Sessions.

AG10 was designed to mimic a naturally-occurring variant of the TTR gene (T119M) that is considered a “rescue mutation” because it has been shown to prevent ATTR in individuals also carrying a pathogenic, or disease-causing, mutation in the other copy of their TTR gene. To our knowledge, AG10 is the only TTR stabilizer in development that has been observed to mimic the “super-stabilizing” properties of this rescue mutation.

All statements other than statements of historical facts, including the statements about future clinical milestones of AG10, including the completion of our ongoing Phase 2 clinical trial and availability of data therefrom, the initiation of Phase 3 clinical trials, the timing of these events, the indications we intend to pursue, the potential benefits available to us from orphan drug designations for AG10, and our possible clinical or other business strategies, are forward-looking statements. Forward-looking statements can be identified by terms such as “believes,” “expects,” “plans,” “potential,” “would” or similar expressions and the negative of those terms. These forward-looking statements are based on our management’s current beliefs and assumptions about future events and on information currently available to management.

These risks include, but are not limited to, risks and uncertainties related to: our limited operating history and historical losses, our liquidity to fund the development of our other product candidates through current and future milestones, our ability to raise additional funding to complete the development and any commercialization of our product candidates, our dependence on the success of our lead product candidate, AG10, results from our clinical trials and pre-clinical studies and those of third parties working in the same area as our product candidate and our dependence on third parties in connection with our manufacturing, clinical trials and pre-clinical studies. Additional risks and uncertainties that could affect our future results are included in the section titled “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our Quarterly Report on Form 10-Q for the quarter ended June 30, 2018, which is available on the SEC’s website at www.sec.gov and our website at eidostx.com.
