Eloxx Pharmaceuticals Reports First Quarter 2021 Financial and Operating Results and Provides Business Update

Acquisition of Zikani Therapeutics, Ribosomal Modulation Company; Combined Company Advancing Ribosomal RNA-Targeted Genetic Therapies

Additional Treatment Arm Added to Ongoing Phase 2 Clinical Studies for Cystic Fibrosis (CF)

Cystic Fibrosis Foundation (CF Foundation) Increases Clinical Trial Funding to Include Europe and Israel

ELX-02 Phase 1 Results Published in Multiple Scientific Journals

WALTHAM, Mass., May 06, 2021 (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 March 31, 2021 and provided a business update.

“The beginning of 2021 has been transformative for Eloxx and was extremely important in laying the groundwork for the future success of ELX-02, our candidate for cystic fibrosis, and in amplifying the potential of Eloxx’s innovative science and be a leader in RNA-targeted genetic therapies. Our enthusiasm has only increased in the short period since the acquisition,” said Sumit Aggarwal, President and Chief Executive Officer of Eloxx. “We remain incredibly excited by the potential of ELX-02 to help treat CF patients affected by nonsense mutations and look forward to completing enrollment in the first four treatment arms by mid-year, and expect to report data in the second half of 2021.”

First Quarter 2021 and Subsequent Highlights

• We acquired Zikani Therapeutics, Inc., a ribosomal modulation company, in an all stock transaction on April 1, 2021.   We believe the acquisition maximizes the potential for ELX-02 for CF, which is currently in Phase 2 development. The acquisition also adds a preclinical stage pipeline in rare diseases and oncology targeting RNA and ribosomal mutations. Eloxx expects to file an Investigational New Drug application for the first oral drug to treat patients with Recessive Dystrophic and Junctional Epidermolysis Bullosa (RDEB and JEB) in 2022. Sumit Aggarwal, former Zikani President and CEO, was appointed President and CEO of Eloxx.
• As previously announced, the new study arm was added to our global Phase 2 clinical program for ELX-02 for the treatment of CF in patients with at least one G542X allele. The Phase 2 clinical program now includes a fifth treatment arm to evaluate safety of ELX-02 in combination with Kalydeco^® (ivacaftor), a FDA-approved CF transmembrane conductance regulator (CFTR) potentiator for the treatment of CF in patients who have at least one mutation in their CF gene amenable to ivacaftor. The Phase 2 trials are designed to evaluate the safety of ELX-02 and assess its biological activity. We remain on track to present data from the first four treatment arms in the second half of this year.
• The CF Foundation extended its funding of our clinical trial program to include Europe and Israel.
• Phase 1 results for ELX-02 were published in multiple medical journals, including:
  • “Targeting G542X CFTR Nonsense Alleles with ELX-02 Restores CFTR Function in Human-Derived Intestinal Organoids” in the Journal of Cystic Fibrosis;
  • “A Randomized, Double-Blind, Placebo-Controlled, Multiple Dose Escalation Study to Evaluate the Safety and Pharmacokinetics of ELX-02 in Healthy Subjects” in the journal Clinical Pharmacology in Drug Development; and
  • “Phase 1 Renal Impairment Trial Results Enable Targeted Individualized Dosing of ELX-02 in Nephropathic Cystinosis Patients” in the Journal of Clinical Pharmacology.

First Quarter 2021 Financial Results

For the three months ended March 31, 2021, we incurred a net loss of $8.7 million or $0.22 per share, which includes $1.3 million in stock-based compensation. For the same period in the prior year, we incurred a net loss of $13.9 million, or $0.35 per share.

Our research and development expenses (R&D) were $4.1 million for the three months ended March 31, 2021, which includes $0.2 million in stock-based compensation. For the same period in the prior year, R&D expenses were $4.8 million. The decrease in R&D expenses was driven by reduced expenses related to the development of ELX-02 due to the impact of the COVID-19 and realignment actions taken in February 2020 that included reductions in R&D headcount and external spending.

Our general and administrative (G&A) expenses were $4.3 million for the three months ended March 31, 2021, which includes $1.1 million in stock-based compensation. For the same period in the prior year, G&A expenses were $5.0 million. The decrease was primarily driven by realignment actions taken in February 2020 that included reductions in general and administrative headcount and external spending.

As of March 31, 2021, we had cash and cash equivalents of $18.2 million, which we expect will be sufficient to fund our operations into the third quarter of 2021.
