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

Started proof-of-concept Phase 2 clinical trial with ELX-02 in up to eight Alport syndrome patients with nonsense mutations; topline results expected in the first half of 2023

On track to submit IND application for ZKN-013 for the treatment of recessive dystrophic epidermolysis bullosa (RDEB) patients with nonsense mutations cells by the end of 2022 or early 2023

WATERTOWN, Mass., Nov. 10, 2022 (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 September 30, 2022 and provided a business update.

“With the recent start of our Phase 2 proof-of-concept trial for ELX-02 for the treatment of Alport Syndrome, we are on track to deliver topline results for the program in the first half of 2023. Alport patients with nonsense mutations have significantly worse clinical outcomes than other Alport patients and have no disease modifying treatment options,” said Sumit Aggarwal, President and Chief Executive Officer of Eloxx. “We have also made significant advancements in our Ribosome Modulating Agents programs, approaching clinical development for ZKN-013 for the treatment of RDEB and generating encouraging preclinical data in multiple indications.”

Third Quarter 2022 and Subsequent Highlights

Alport Syndrome

• Eloxx started a 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). Alport syndrome is a rare genetic disorder characterized by kidney disease with high levels of proteinuria, hearing loss and eye abnormalities. Patients will be dosed for two months with a three month follow-up. Trial primary endpoints include safety while secondary endpoints are reduction in proteinuria and induction of COL4A5 protein expression in the kidney. Initial 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)

• Eloxx continues to expect to file an Investigational New Drug (IND) application to start a First in Human (FIH) Phase 1 study of ZKN-013 by the end of 2022 or early 2023.

Familial Adenomatous Polyposis (FAP)

• Eloxx continues to evaluate the potential of 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. Eloxx is currently preparing an IND application.

Class 1 Cystic Fibrosis (CF)

• A Phase 2 combination study data readout of ELX-02 with ivacaftor in CF patients with nonsense mutations did not meet efficacy endpoints but did confirm drug activity for ELX-02 and demonstrated need for higher drug exposure in lung to generate therapeutic benefit. Eloxx aims to complete IND enabling studies for inhaled ELX-02. The path forward in CF is to be determined together with the CF Foundation.

TURBO-ZM™ Platform

• Recent advancements have demonstrated the potential of Eloxx’s TURBO-ZM chemistry technology platform to develop novel Ribosome Modulating Agents (RMAs).
  • Two posters were presented at the 34^th EORTC-NCI-AACR Symposium in late October 2022 demonstrating the potential of RMAs to treat MYC-driven cancers. Preclinical data demonstrated activity against subtypes of colorectal cancer (ZKN-157) and small cell lung cancer (ZKN-217).
  • A poster was presented at the International Symposium on Medicinal Chemistry in early September. A phenotypic screen of our RMA library identified showed selective hits for cancer cell lines and demonstrated responsive structure-activity relationship.
  • In Eloxx’s program to identify RMAs for further development in the treatment of Class 1 CF, which is supported by the CF Foundation, screening has identified approximately 50 oral RMAs with promising functional CFTR activity.

Third Quarter 2022 Financial Results

For the three months ended September 30, 2022, we incurred a net loss of $7.5 million, or $0.09 per share, which included $0.7 million in stock-based compensation. For the same period in the prior year, we incurred a net loss of $9.9 million, or $0.11 per share, which included $2.2 million in stock-based compensation.

Our R&D expenses were $4.9 million for the three months ended September 30, 2022, which includes $0.3 million in stock-based compensation. For the same period in the prior year, R&D expenses were $5.2 million, which included $0.4 million of stock based compensation. The decrease was related to a decrease in clinical trial expenses related primarily to CF Foundation funded activities, and a decrease in salaries and other personnel costs.

Our general and administrative (G&A) expenses were $2.3 million for the three months ended September 30, 2022, which includes $0.4 million in stock-based compensation. For the same period in the prior year, G&A expenses were $5.0 million, which included $1.9 million of stock-based compensation. The decrease was primarily related to a decrease in salaries and other personal related costs due to reduced headcount, a decrease in expenses attributable to professional and consulting fees, and a decrease in stock-based compensation expense due primarily to option modifications of former executives in 2021.

As of September 30, 2022, we had unrestricted cash and cash equivalents of $24.6 million. The Hercules Term Loan Agreement contains customary affirmative and negative covenants, which among others require us to maintain a minimum qualified cash balance. As of September 30, 2022, we were in compliance with all debt covenants. Our expectation is that our current cash position will be sufficient to fund our operations into the fourth quarter of 2023 assuming that we can comply with our lender’s minimum cash covenant by either raising additional capital or working with our lender to restructure the covenants.
