Eloxx Pharmaceuticals Intends to Advance ELX-02 into Pivotal Trial for the Treatment of Alport Syndrome with Nonsense Mutations Following Achievement of Remission in Patient in Phase 2 Study
Patient treated in trial achieved a remission after eight weeks of treatment, demonstrating a significant reduction in proteinuria
ELX-02 well-tolerated in study, with no discontinuations to date
WATERTOWN, Mass., May 24, 2023 (GLOBE NEWSWIRE) -- Eloxx Pharmaceuticals, Inc. (NASDAQ: ELOX), a leader in ribosomal RNA-targeted genetic therapies for rare diseases, today announced that the company intends to advance ELX-02 into a pivotal trial for the treatment of Alport syndrome with nonsense mutations, following the achievement of remission in one patient in its Phase 2 clinical study. The patient demonstrated a significant reduction in urine protein creatinine ratio (UPCR) from baseline. Consistent with prior clinical studies, ELX-02 was well tolerated in this trial.
“The achievement of a remission in one of the first two patients with Alport syndrome with nonsense mutations in this trial of ELX-02 is a very encouraging result, as patients with this rare disease rarely demonstrate a reduction in proteinuria,” said Detlef Bockenhauer, MD., Ph.D., Professor of Paediatric Nephrology at University College London and Honorary Consultant at Great Ormond Street Hospital NHS Foundation Trust, London. “Based on the efficacy and tolerability to date, additional clinical testing is warranted in this patient population in need of disease-modifying treatments.”
Topline Results of ELX-02 Phase 2 Trial for Alport Syndrome
Eloxx intends to provide more detailed results from the trial at an upcoming medical meeting.
About the Phase 2 Clinical Study
This Phase 2 trial includes Alport syndrome patients with Col4A5 and Col4A3/4 nonsense mutations in the COL4 gene. Patients will be dosed with ELX-02 for two months with a three month follow-up. In addition to the primary endpoint of safety, the key secondary efficacy endpoint of change from baseline in proteinuria will be measured every two weeks. Treatment effect on proteinuria is a well-validated surrogate endpoint for several renal indications and may be a good predictor of treatment outcomes. For eligible patients, expression of COL4 will also be measured at the end of the two month treatment period.
About Alport syndrome
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 6% to 7% of Alport syndrome patients, or approximately 9,400 to 12,750 individuals, are estimated to have nonsense mutations. These patients have significantly worse clinical outcomes than other Alport patients and have no disease modifying treatment options.
