Eloxx Pharmaceuticals Announces Key Corporate Accomplishments

Data from Eloxx’s proof-of-concept trial in patients with nonsense mutation Alport Syndrome (NMAS) presented in late-breaking presentation at American Society of Nephrology (ASN) Kidney Week

New protein analyses confirm production of both collagen alpha 4 and collagen alpha 5 in patients post treatment with ELX-02

Results justify the need to conduct a larger clinical trial of ELX-02 in NMAS to confirm clinical benefit

U.S. Food and Drug Administration (FDA) allows for continued dosing of subjects in Phase 1 trial of ZKN-013

WATERTOWN, Mass., Nov. 12, 2024 (GLOBE NEWSWIRE) -- Eloxx Pharmaceuticals, Inc. (OTC: ELOX), a leader in ribosomal RNA-targeted genetic therapies for rare diseases with nonsense mutations, today provided significant key corporate updates.

“The demonstration of both collagen alpha 4 and collagen alpha 5 in patients in our proof-of-concept study of ELX-02 in NMAS patients is an important milestone in the development of this crucial potential therapy. These new results, presented in a late-breaking presentation at ASN Kidney Week, strongly justify the need to conduct a larger trial to confirm these encouraging results in this underserved patient population,” said Sumit Aggarwal, President and Chief Executive Officer of Eloxx. “Also, the FDA allowing for continued dosing of subjects in the Phase 1 trial for ZKN-013 is a substantial achievement for the program and makes Eloxx eligible for the next milestone payment in the company’s agreement with Almirall, once confirmed by our partner, Almirall.”

Additional Alport Syndrome data presented at the ASN Kidney Week

In late October, Daniel Gale, Professor of Nephrology at University College London Department of Renal Medicine, presented additional results from Eloxx’s proof-of-concept study in three NMAS patients treated with ELX-02 in a late-breaking presentation at ASN Kidney Week. The presentation was titled: “Small molecule premature termination codon readthrough therapy: a Phase 2 pediatric and adult trial in Nonsense Mutation Alport syndrome” at the ASN Kidney Week conference.

“Although this was a small trial of limited duration, the appearance of new Type IV Collagen in the glomerular basement membranes is the first time a missing podocyte protein has been reconstituted in a human and provides evidence that ELX-02 is acting as intended in the kidneys of patients. A longer, controlled study will be needed to quantify the clinical effectiveness of this therapy,” said Professor Gale.

New protein immunostaining and mass spectrometry analyses that were presented, confirmed the production of both collagen a4 (IV) and collagen a5 (IV) proteins in NMAS patients treated with ELX-02. Prior to treatment, collagen a4 (IV) and a5 (IV) were absent in the glomerulus in all three patients. Post treatment biopsy of the patient with the largest improvement in Filtrtion Slit Density showed a 34% increase in collagen a4 (IV) immunostaining intensity and presence of collagen a3/a4/a5 (IV) peptide with a greater than 6-fold increase in collagen a4 and detectable collagen a5 consistent with formation of a functional protein induction. No collagen alpha 5 was detected pre-treatment in this patient.

These additional data support ELX-02’s mechanism of protein induction, and the observed morphology change and reduced foot process effacement in all the patients that was previously reported. The results also justify the conduct of a larger clinical trial with longer ELX-02 treatment duration to validate the observed clinical benefit in NMAS patients.

The demonstrated readthrough of premature stop codons also suggests ELX-02 has potential in other rare kidney diseases, including autosomal dominant polycystic kidney disease and cystinosis.

FDA allows for continued dosing of subjects in Phase 1 trial of ZKN-013

Following successful dosing of the initial subjects, FDA has allowed continued dosing of healthy volunteers for ZKN-013 for the treatment of recessive dystrophic epidermolysis bullosa and junctional epidermolysis bullosa. Eloxx is awaiting confirmation from Almirall to proceed with the study based on their review of the results and FDA feedback.

ZKN-013 has been exclusively licensed to Almirall, S.A. (BME:ALM), who has global rights to develop and commercialize ZKN-013. Under the terms of the license agreement, Eloxx is eligible for additional development, regulatory and sales milestones of up to $470 million as well as tiered royalties on any potential global sales.
