Endogena Therapeutics Receives US FDA Fast Track Designation for EA-2353 for the Treatment of

San Francisco, USA; Toronto, Canada; Zürich, Switzerland, February 6, 2023

Endogena Therapeutics Inc., a clinical-stage biotech company focused on the development of endogenous regenerative medicines, announced today that the US Food and Drug Administration (FDA) has designated the investigation of EA-2353 for the treatment of retinitis pigmentosa (RP) as a Fast Track development program. Fast Track is a process designed to enable patients to benefit earlier from important new drugs for serious conditions. 

EA-2353 takes a novel, small-molecule approach and selectively activates endogenous retinal stem and progenitor cells, which differentiate into photoreceptors and can potentially preserve or restore visual function. This gene-independent treatment approach has significant advantages in RP, which has multiple genetic causes. EA-2353 was granted orphan drug designation by the US FDA in May 2021.

RP is a serious and debilitating condition. It consists of a group of inherited diseases causing slow and progressive retinal degeneration and loss of vision, for which there is currently no treatment for most patients. It is a leading cause of inherited blindness, with an estimated 1.5 million people worldwide presently affected.

Endogena Therapeutics is currently conducting a phase 1/2a dose-escalation study in collaboration with our lead investigator, Mark Pennesi, MD, PhD, Professor of Ophthalmology at the Casey Eye Institute in Oregon, USA, to examine the safety, tolerability and preliminary efficacy of EA-2353 administered by intravitreal injection in patients with RP ( identifier: NCT05392751). A total of 14 patients with RP due to any pathologic genetic mutation are being recruited across up to six sites in the USA, and the first patient was dosed in July 2022.

This Fast Track designation will enable Endogena Therapeutics to have more frequent communications with the US FDA on the development of EA-2353 and allow more rapid regulatory review of the future new drug application.

Matthias Steger, PhD, MBA, CEO of Endogena, said: “This acknowledgement by the FDA of the potential of EA-2353 for RP gives hope for patients living with this devastating degenerative disease. It is a significant milestone for our company, our investors, and gives recognition to our dedicated team at Endogena, who have been working for the past six years to reach this point.”

Endogena’s artificial intelligence-driven drug discovery platform, combined with cutting edge knowledge of molecular pathways that regulate retinal stem cells and retinal pigment epithelial cells, provides a potential new treatment paradigm to tackle degenerative conditions related to aging and genetic disorders. Beyond EA-2353, other products in Endogena’s pipeline include a treatment for dry age-related macular degeneration (AMD), which is approaching IND-enabling studies, and earlier programs in idiopathic pulmonary fibrosis (IPF) and hematopoietic recovery.


About Endogena

Endogena Therapeutics Inc. is a clinical-stage biotech company that discovers and develops first-in-class endogenous regenerative medicines to repair and regenerate tissues and organs. Its approach has the potential to change the way degenerative conditions related to aging and genetic disorders are treated. The concept is based on selective regulation of endogenous adult stem- and progenitor cells for controlled tissue repair by small molecules. Endogena’s most advanced programs target degenerative diseases of the eye, including retinitis pigmentosa and geographic atrophy (secondary to AMD). Endogena is registered in San Francisco, USA, headquartered in Zuerich, Switzerland, and holds a research facility at JLABS in Toronto Canada.
