Eloxx Pharmaceuticals Announces New Development Program for ELX-02 for the Treatment of Alport Syndrome
Eloxx Pharmaceuticals (ELOX) has expanded its ELX-02 program to target Alport syndrome, a rare kidney disease caused by mutations in collagen genes. The initiation of a proof-of-concept clinical trial is expected in the second half of 2022, assessing up to eight patients with nonsense mutations. ELX-02 has shown promise in preclinical studies, demonstrating significant readthrough in COL4A5 mutations. Topline results from the trial are anticipated in the first half of 2023, marking a potential breakthrough in treating this underserved patient population.
- Expansion of ELX-02 program to include Alport syndrome, targeting a rare genetic disease.
- Preclinical results indicate significant readthrough in COL4A5 mutations, which may lead to therapeutic benefits.
- Expected initiation of a clinical trial in the second half of 2022, with topline results projected for the first half of 2023.
- None.
Strong rationale for development for Alport syndrome as ELOX-02 has demonstrated significant readthrough in COL4A5 nonsense mutations in preclinical studies and is preferentially transported to kidney
Initiation of proof-of-concept clinical trial expected in second half of 2022; topline results expected in first half of 2023
WATERTOWN, Mass., March 30, 2022 (GLOBE NEWSWIRE) -- Eloxx Pharmaceuticals, Inc. (NASDAQ: ELOX), a leader in ribosomal RNA-targeted genetic therapies for rare diseases, today announced it has expanded the ELX-02 development program to include the treatment of Alport syndrome, a rare kidney disease. Clinical testing of ELX-02 in Alport syndrome is expected to initiate in the second half of 2022, with topline results expected in the first half of 2023.
Alport syndrome is a genetic disorder characterized by kidney disease with high levels of proteinuria, hearing loss and eye abnormalities caused by mutations in the genes (COL4A3, COL4A4, and COL4A5) needed for production of type 4 collagen. Approximately
Eloxx believes there is a strong rationale to pursue clinical development of ELX-02 in Alport syndrome, based on encouraging preclinical results demonstrating potentially therapeutic levels of readthrough, ability to deliver high drug concentrations in the kidney relative to plasma at clinically tolerable dose levels, and the clinical readthrough results seen in our Phase 2 cystic fibrosis trial.
“We are beginning to fully capture the potential of ELX-02 as a novel readthrough agent in rare diseases with significant need with the addition of a new program in Alport syndrome,” said Sumit Aggarwal, President and Chief Executive Officer of Eloxx.
"For the global patient community, this study represents a groundbreaking and hopeful step as the first to explore a potential curative therapy in a specific genetic mutation of our rare disease,” notes Lisa Bonebrake, Executive Director of the U.S. based patient support group, Alport Syndrome Foundation.
ELX-02 is preferentially taken up in the kidney, resulting in an expected greater than 50-fold exposure in the kidneys compared to plasma. In recently published preclinical studies, ELX-02 has demonstrated readthrough in COL4A5 mutations, which represent
Eloxx intends to initiate a proof-of-concept clinical trial in up to eight Alport syndrome patients with nonsense mutations in the second half of 2022. Patients will be dosed for two months with a three month follow-up. Trial primary endpoints will include safety, while secondary endpoints will include reduction in proteinuria and induction of COL4A5 protein expression in the kidney. Topline results are expected in the first half of 2023.
About nonsense mutations
Nonsense mutations cause a premature stop codon in the mRNA resulting in less than full length or los of function proteins. These remain highly underserved with no approved disease modifying therapies. An estimated 10
About Eloxx Pharmaceuticals
Eloxx Pharmaceuticals, Inc. is engaged in the science of ribosome modulation, leveraging its innovative TURBO-ZM™ chemistry technology platform in an effort to develop novel Ribosome Modulating Agents (RMAs) and its library of Eukaryotic Ribosome Selective Glycosides (ERSGs). Eloxx’s 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 clinical development, focusing on cystic fibrosis (US Trial NCT04135495, EU/IL Trial NCT04126473). Eloxx also has preclinical programs focused on select rare diseases, including inherited diseases, cancer caused by nonsense mutations, kidney diseases, including autosomal dominant polycystic kidney disease, as well as rare ocular genetic disorders.
