Eidos Therapeutics Reports First Quarter 2019 Financial Results

Eidos Therapeutics, Inc. (Eidos) (Nasdaq:EIDX),  today reported its financial results for the first quarter ended March 31, 2019 and provided an update on the company’s recent achievements.

“The initiation of our Phase 3 ATTRibute-CM study in the first quarter of 2019 marks another key milestone in our focused effort to make AG10 available for the significant unmet need in transthyretin (TTR) amyloidosis (ATTR),” said Neil Kumar PhD, chief executive officer of Eidos. “In our prior clinical studies, AG10 demonstrated near-complete stabilization of TTR and significantly increased serum TTR, a biomarker associated with survival in ATTR-CM patients. Based on these data, we believe AG10 may demonstrate a meaningful benefit in this patient population.”

Recent Achievements and Upcoming Milestones

• Initiated Phase 3 study of AG10 in ATTR-CM (ATTRibute-CM)
• Published Phase 2 data of AG10 in ATTR-CM in the Journal of the American College of Cardiology (JACC)
• Presented sub-group analysis of Phase 2 data in ATTR-CM at American College of Cardiology (ACC) Scientific Sessions
• Plan to initiate Phase 3 study of AG10 in ATTR-PN (ATTRibute-PN) in the second half of 2019
• Plan to present data from the open label extension of the Phase 2 study of AG10 in ATTR-CM in the fourth quarter of 2019

First Quarter Financial and Operating Results

Cash and cash equivalents totaled $147.1 million at March 31, 2019 compared with $157.1 million at December 31, 2018.

Eidos reported a net loss attributable to common stockholders of $11.7 million or $0.32 per common share, for the first quarter of 2019, as compared to a net loss attributable to common stockholders of $8.0 million or $1.81 per common share for the first quarter of 2018. The increase in net loss attributable to common stockholders was driven primarily by research and development expenses related to AG10 clinical trials and other pre-clinical studies, and general and administrative expenses for operations.

Research and development expenses for the first quarter of 2019 were $8.5 million, as compared to $5.7 million for the same period in the prior year. Research and development expenses for the first quarter included costs related to contract manufacturing, the preparation for and conduct of AG10 clinical trials.

General and administrative expenses for the first quarter of 2019 were $4.0 million, as compared to $2.3 million for the same period in the prior year. The increase in general and administrative expense in these periods was due primarily to an increase in professional service fees, salaries and employee-related expense primarily due to an increase in headcount to support the growth of our operations, and other administrative expenses.

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. In a Phase 2 clinical trial in subjects with symptomatic ATTR-CM, AG10 was generally well tolerated, demonstrated >90% average TTR stabilization at day 28, and increased serum TTR concentrations, a prognostic indicator of survival in a retrospective study of ATTR-CM patients, in a dose-dependent manner. AG10 is currently being studied in an open-label extension of a Phase 2 clinical trial in patients with ATTR-CM, and patient enrollment has begun for a Phase 3 clinical trial of AG10 in patients with ATTR-CM (ATTRibute-CM).

AG10 was designed to mimic a naturally-occurring variant of the TTR gene (T119M) that is considered a rescue mutation because co-inheritance has been shown to prevent ATTR in individuals also inheriting a pathogenic, or disease-causing, mutation in the TTR gene. To our knowledge, AG10 is the only TTR stabilizer in development that has been observed to mimic the stabilizing structure of this rescue mutation.

About transthyretin amyloidosis (ATTR)

ATTR represents a significant unmet medical need with a large patient population and an inadequate current standard of care. ATTR is caused by the destabilization of TTR due to inherited mutations or aging and is commonly divided into three distinct categories: wild-type ATTR cardiomyopathy (ATTRwt-CM), mutant ATTR cardiomyopathy (ATTRm-CM), and ATTR polyneuropathy (ATTR-PN). The worldwide prevalence of each disease is approximately 400,000 patients, 40,000 patients and 10,000 patients, respectively.

All three forms of ATTR are progressive and fatal. For patients with ATTRwt-CM and ATTRm-CM, symptoms usually manifest later in life (age 50+), with median survival of three to five years from diagnosis. ATTR-PN either presents in a patient's early 30s or later (age 50+), and results in a median life expectancy of five to ten years from diagnosis. Progression of all forms of ATTR causes significant morbidity, impacts productivity and quality of life, and creates a significant economic burden due to the costs associated with progressively greater patient needs for supportive care.
