WATERTOWN, Mass., Nov. 09, 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 and nine months ended September 30, 2021 and provided a business update.

“We continue to make significant progress across our portfolio of therapeutic programs,” said Sumit Aggarwal, President and Chief Executive Officer of Eloxx. “We are on track to report data from the ongoing Phase 2 clinical trials for ELX-02 in the fourth quarter of 2021. In addition, our preclinical programs continue to advance demonstrating the potential of our oral RMAs. We intend to provide additional updates on these programs in the coming quarters.”

Third Quarter 2021 and Subsequent Highlights

Class 1 Cystic Fibrosis

• Ongoing ELX-02 Phase 2 clinical trials in CF patients affected by nonsense mutations in the CFTR (CF transmembrane conductance regulator) gene are designed to evaluate the safety of ELX-02 and assess short-term biological activity in patients.
  • We remain on track to report data from the monotherapy arms of the ELX-02 clinical trials in the fourth quarter of 2021. In addition, we are continuing to enroll additional patients to support Phase 3 clinical trial planning.
  • As previously announced, the U.S. Food and Drug Administration granted Fast Track designation for ELX-02. Fast Track Designation is granted to drugs being developed for the treatment of serious or life-threatening diseases or conditions where there is an unmet medical need.
  • Biological activity is being assessed by changes in sweat chloride, a surrogate marker for restoring CFTR activity. For comparison, Orkambi, an FDA-approved combination CF agent (Lumacaftor/Ivacaftor), demonstrated mid-single digit reductions in sweat chloride over one- to two-week study durations in a similar trial setting. In addition, Symdeko, another FDA-approved combination agent, demonstrated low- to mid-single digit reductions in sweat chloride over 28 days.
  • Patient dosing in the expansion arm, which includes a combination of ELX-02 and the CFTR protein potentiator, Kalydeco (ivacaftor), is expected to begin by the end of 2021, with topline results expected in the first half of 2022.

• Began evaluation of inhaled (nebulizer-based) delivery of the current subcutaneous formulation of ELX-02. This has the potential to further improve the activity of ELX-02 as a single agent and in combination with other drugs given potential for increased drug exposure in the lung versus plasma. An Investigational New Drug (IND) application is expected in 2H 2022.
• Presented preclinical data at the 2021 North American Cystic Fibrosis Conference demonstrating that significantly greater than 75% of patient derived organoids with ultra rare premature termination codon (PTC) mutations and with no residual CFTR function show swelling response to treatment with ELX-02.
  

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

• ZKN-013 is advancing into IND-enabling studies for the treatment of RDEB and JEB. Good Laboratory Practice (GLP) safety studies are expected to begin by the end of 2021. We remain on track to file an IND in 2022.
  

Rare Inherited and Targeted Oncology

• Continued to advance our preclinical oncology pipeline, which is focused on rare inherited cancers with driver nonsense mutations and cancers with driver mutations in the ribosome.
• Our lead program is for the treatment of patients with Familial Adenomatous Polyposis (FAP).
  • An 8-week study in APCMin (multiple intestinal neoplasia) mice to evaluate the potential of RMAs to treat FAP. The APCMin mouse is a translationally validated model for drug development for FAP. This study in APCMin will evaluate polyp number and size in ZKN013 treated mice versus control mice. We expect to report results from this study in the fourth quarter of 2021.
    
• Cancer cell line and xenograft mouse studies ongoing to evaluate the response to treatment with RMAs to advance first-in-class onco-ribosome targeted inhibitors for oncology therapy.
  

Corporate

• Eloxx entered into a debt facility with Hercules Capital, Inc., a specialty financing lender for life science and technology companies, that provides for borrowings of up to $30.0 million. Eloxx has drawn the initial tranche of $12.5 million and used the proceeds to repay in full amounts outstanding under the Eloxx’ existing debt facility. The remaining funds under the new facility will be available in additional tranches upon the achievement of specific clinical milestones or other terms and conditions.
• Ali Hariri, M.D., joined Eloxx as Chief Medical Officer, overseeing clinical development efforts for the company’s promising pipeline of therapies to treat rare diseases.

Third Quarter 2021 Financial Results

For the three months ended September 30, 2021, we incurred a net loss of $9.9 million, or $0.11 per share, which includes $2.2 million in stock-based compensation. For the same period in the prior year, we incurred a net loss of $6.6 million, or $0.16 per share. Results for the third quarter of 2021 included costs related to the acquisition of Zikani. Since the closing date of the acquisition, the results of Zikani’s operations have been included in the Eloxx’ condensed consolidated financial statements.

Our research and development expenses (R&D) were $5.2 million for the three months ended September 30, 2021, which includes $0.4 million in stock-based compensation. For the same period in the prior year, R&D expenses were $3.4 million. The increase was primarily related to expenses related to the continued development of ELX-02 due to the impact of the COVID-19 pandemic in the prior year period, an increase in salaries and other personnel related costs, and an increase in operational facilities.

Our general and administrative (G&A) expenses were $5.0 million for the three months ended September 30, 2021, which includes $1.9 million in stock-based compensation. For the same period in the prior year, G&A expenses were $2.9 million. The increase was primarily related to an increase in stock-based compensation expense, an increase in salaries and other personnel related costs, as well as an increase in legal, accounting and other professional fees.

As of September 30, 2021, we had cash and cash equivalents of $52.4 million, which we expect will be sufficient to fund our operations into the first quarter of 2023.
