Eloxx Pharmaceuticals Reports Fourth Quarter 2022 Financial and Operating Results and Provides Business Update

Three patients now dosed in Phase 2 clinical study evaluating ELX-02 for the treatment of Alport syndrome; encouraging initial reduction in proteinuria has been observed in one patient to date

Investigational New Drug (IND) application for ZKN-013 filed for treatment of recessive dystrophic epidermolysis bullosa (RDEB)

WATERTOWN, Mass., April 03, 2023 (GLOBE NEWSWIRE) — Eloxx Pharmaceuticals, Inc. (NASDAQ: ELOX), a leader in ribosomal RNA-targeted genetic therapies for rare diseases, today reported its financial results for the three months ended December 31, 2022 and provided a business update.

“With topline data expected for ELX-02 in Alport syndrome in the first half of 2023, we believe we are approaching a significant milestone for the company, to advance into our first Phase 3 study, with the potential to create significant value for both patients and shareholders,” said Sumit Aggarwal, President and Chief Executive Officer of Eloxx. “Positive data from the trial would also be a validation of our potential to treat other rare kidney diseases and develop small molecule genetic therapy products.”

Fourth Quarter 2022 and Subsequent Highlights

Alport Syndrome

• Eloxx has now dosed three patients with ELX-02 in the ongoing proof-of-concept Phase 2 open-label clinical trial (NCT05448755) in up to eight Alport syndrome patients with nonsense mutations in the Collagen Type 4 genes, (COL4A3, COL4A4, and COL4A5). Encouraging initial reduction in proteinuria has been observed in one patient to date. Alport syndrome is a rare genetic disorder characterized by kidney disease with high levels of proteinuria, hearing loss and eye abnormalities. We will be evaluating expression of COL IV protein in these three patients at the end of dosing and measuring proteinuria every two weeks. Topline results are expected in the first half of 2023.
• Eloxx presented a poster highlighting the activity of ELX-02 across a range of COL4A5 mutations in preclinical models at the American Society of Nephrology (ASN) Kidney Week 2022 Conference in early November 2022.

Recessive Dystrophic Epidermolysis Bullosa (RDEB) and Junctional Epidermolysis Bullosa (JEB)

• In March 2023, Eloxx announced the submission of an Investigational New Drug (“IND”) application with the U.S. Food and Drug Administration for ZKN-013 for the treatment of recessive Dystrophic Epidermolysis Bullosa (RDEB) with nonsense mutations. RDEB is a rare skin disease characterized by mutations in Collagen 7 gene.
• Recent preclinical results demonstrated read-through activity of ZKN-013 in multiple COL7 genotypes across multiple RDEB patient derived fibroblasts and keratinocytes. Read-through activity resulted in up to an 18-fold increase in full-length COL VII protein levels. Prolonged treatment with ZKN-013 further increased COL VII protein levels. Functionality of the restored full-length COL VII protein was confirmed. These results have been accepted for presentation at an upcoming medical conference.

Familial Adenomatous Polyposis (FAP)

• Eloxx also plans to develop ZKN-013 to treat FAP, targeting a subset of patients that have nonsense mutations in the Adenomatous Polyposis Coli (APC) gene that is truncated in these patients. An additional IND filing for ZKN-013 for treatment of FAP is planned in the first half of 2023.
• In January 2023, Eloxx published positive results from a study in the APC^Min (multiple intestinal neoplasia) model evaluating the potential of ZKN-013 to treat FAP. The APC^Min mouse is a translationally validated model for drug development for FAP. In the APC^Min model, treatment with ZKN-013 demonstrated a decrease in intestinal polyps and adenomas, resulting in increased survival. The publication also included in vitro and in vivo results demonstrating that ZKN-013 inhibited the growth of human colon carcinoma cells with APC nonsense mutations, and promoted read through of premature stop codons in the APC gene, leading to functional restoration of full-length APC protein.

Fourth Quarter 2022 Financial Results

For the three months ended December 31, 2022, we incurred a net loss of $6.3 million, or $2.92 per share, which included $0.6 million in stock-based compensation. For the same period in the prior year, we incurred a net loss of $12.1 million, or $5.60 per share, which included $1.6 million in stock-based compensation.

R&D expenses were $3.3 million for the three months ended December 31, 2022, which includes $0.3 million in stock-based compensation. For the same period in the prior year, R&D expenses were $7.9 million, which included $0.6 million of stock-based compensation. The decrease was related to a decrease in clinical trial expenses related primarily to Cystic Fibrosis Foundation funded activities, and a decrease in salaries and other personnel costs.

General and administrative (G&A) expenses were $2.7 million for the three months ended December 31, 2022, which includes $0.3 million in stock-based compensation. For the same period in the prior year, G&A expenses were $3.7 million, which included $1.0 million of stock-based compensation. The decrease was primarily related to a decrease in salaries and other personal related costs due to reduced headcount and outsourcing certain functions, a decrease in expenses attributable to professional and consulting fees, and a decrease in stock-based compensation expense.

As of December 31, 2022, we had unrestricted cash and cash equivalents of $19.2 million. In March 2023, we amended the terms of the Hercules Term Loan Agreement and repaid $7.5 million of the outstanding principal. The minimum qualified cash balance requirement was reduced to $2.25 million and Eloxx will be required to make principal payments, plus interest, beginning in September 2023. Assuming that we initiate Phase 3 clinical trial activities in the third quarter of 2023, our expectation is that our current cash position and assuming maintaining compliance with our debt covenants, will be sufficient to fund our operations into the third quarter of 2023.
