WALTHAM, Mass., Aug. 26, 2020 (GLOBE NEWSWIRE) -- Eloxx Pharmaceuticals, Inc., (NASDAQ: ELOX) a clinical-stage biopharmaceutical company dedicated to the discovery and development of novel therapeutics to treat cystic fibrosis and other diseases caused by nonsense mutations limiting production of functional proteins, today announced that two abstracts will be presented at theNorth American Cystic Fibrosis Conference (NACFC) to be held virtually starting on October 7, 2020. The two abstracts will be showcased in the NACFC virtual poster gallery and electronically published as a supplement to Pediatric Pulmonology. These virtual posters will be available to registered attendees on the NACFC online conference platform starting on October 7, 2020.

We are pleased to be presenting additional preclinical study results in cystic fibrosis at the 2020 NACFC virtual conference which demonstrate ELX-02s selectivity for read-through of premature stop codons versus native stop codons and its ability to restore production of functional CFTR in patient-derived organoids, said Dr.Gregory Williams, Chief Executive Officer ofEloxx Pharmaceuticals. We are advancing our Phase 2 clinical trials for ELX-02 in cystic fibrosis in Europe, Israel and the U.S., and we believe the data from our preclinical programs substantially de-risk this program. We look forward to reporting top line data from our proof of concept Phase 2 clinical trials as quickly as possible.

The details for the two ELX-02 poster presentations are:

Poster Session Presentation Title: ELX-02 Generates Protein Via Premature Stop Codon Read-through Without Inducing Native Stop Codon Read-through Proteins Poster #: 433 Presenter:Dr.Dan Crawford,Eloxx PharmaceuticalsTime: Available virtually to registered attendees starting on October 7, 2020

Poster Session Presentation Title: CFTR Restoration By ELX-02 Across CF Nonsense Genotypes: Utilizing Patient-Derived Organoids to Survey Responsive Alleles Poster #: 383 Presenter:Dr.Matthew Goddeeris,Eloxx Pharmaceuticals Time: Available virtually to registered attendees starting on October 7, 2020

About Eloxx Pharmaceuticals

Eloxx Pharmaceuticals, Inc. is a clinical-stage biopharmaceutical company developing novel RNA-modulating drug candidates (designed to be eukaryotic ribosomal selective glycosides) that are formulated to treat rare and ultra-rare premature stop codon diseases. Premature stop codons are point mutations that disrupt protein synthesis from messenger RNA. As a consequence, patients with premature stop codon diseases have reduced or eliminated protein production from the mutation bearing allele accounting for some of the most severe phenotypes in these genetic diseases. These premature stop codons have been identified in over 1,800 rare and ultra-rare diseases. Read-throughtherapeutic development is focused on extending mRNA half-life and increasing protein synthesis by enabling the cytoplasmic ribosome to read through premature stop codons to produce full-length proteins. Eloxxs lead investigational product candidate, ELX-02, is a small molecule drug candidate designed to restore production of full-length functional proteins. ELX-02 is in the early stages of clinical development focusing on cystic fibrosis. ELX-02 is an investigational drug that has not been approved by any global regulatory body. Eloxxs preclinical candidate pool consists of a library of novel drug candidates designed to be eukaryotic ribosomal selective glycosides identified based on read-through potential. Eloxx also has preclinical programs focused on kidney diseases including autosomal dominant polycystic kidney disease, as well as rare ocular genetic disorders. Eloxx is headquartered in Waltham, MA, with operations in Rehovot, Israel and Morristown, NJ. For more information, please visit www.eloxxpharma.com.
