Eloxx Pharmaceuticals Reports Second Quarter 2021 Financial and Operating Results and Provides ...

August 16, 2021 GMT

Added Additional Treatment Arm and Provided Enrollment Update for Ongoing ELX-02 Phase 2 Clinical Trials for Cystic Fibrosis (CF)

Nominated ZKN-013 as Lead Candidate for Recessive Dystrophic Epidermolysis Bullosa (RDEB) and Junctional Epidermolysis Bullosa (JEB) Programs

Advanced Multiple Preclinical Rare Inherited and Targeted Oncology Programs

Received Funding Award from Cystic Fibrosis Foundation to Develop Ribosome Modulating Agents (RMAs) with TURBO-ZMPlatform

Raised Approximately $52M in Gross Proceeds Through Public Offering

WATERTOWN, Mass., Aug. 16, 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 June 30, 2021, and provided a business update.


“Since the acquisition of Zikani Therapeutics in early April, we have made tremendous progress across our portfolio of novel therapeutic programs,” said Sumit Aggarwal, President and Chief Executive Officer of Eloxx. “In CF, we remain on track to report data from the ongoing Phase 2 clinical trials for ELX-02, while we are also preparing for combination studies of ELX-02 and ivacaftor and commencing efforts to evaluate inhaled delivery of ELX-02. Beyond CF, we continue to advance our preclinical programs to demonstrate the potential of our oral RMAs. We intend to provide additional insight into these programs in the coming quarters.”

Second 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.
    • As previously announced, based on enrollment as of the end of June 2021, we remain on track to report data from the monotherapy arms of the ELX-02 clinical trials in the fourth quarter of 2021. We are continuing to enroll additional patients to support Phase 3 clinical trial planning.
    • Biological activity is being assessed by changes in sweat chloride, a surrogate marker for restoring CFTR activity. For comparison, Orkambi, an FDA-approved CF agent, demonstrated mid-single digit reductions in sweat chloride over one- to two-week study durations in a similar trial setting.
    • 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. Previously disclosed preclinical organoid experiments have demonstrated that the addition of Kalydeco to ELX-02 can enhance activity up to three-fold.
    • Safety Review Committee has approved advancement to highest dose level to be studied.

  • Began evaluation of inhaled (nebulizer-based) delivery of the current subcutaneous formulation of ELX-02. Preclinical rodent studies of ELX-02 and other aminoglycosides have demonstrated 30- to 100-fold higher drug concentration in the lung versus plasma. This has the potential to further improve the activity of ELX-02 as both a single agent and in combination with other drugs.
  • Received an award of up to $2.6M from the Cystic Fibrosis Foundation to identify optimized oral Ribosome Modulating Agents (RMAs) with our TURBO-ZM™ Platform for further development for the treatment of CF patients with nonsense mutations.

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

  • Nominated ZKN-013 as the drug candidate to move 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 submission in 2022.
    • In preclinical experiments, treating RDEB patient-derived fibroblasts and keratinocytes with ZKN-013 showed clinically relevant restoration of full-length Collagen 7A (COL7A) across multiple genotypes in a dose dependent manner.
    • In a non-GLP animal toxicity study, ZKN-013 demonstrated a substantial safety margin with therapeutically sufficient drug levels in skin with chronic dosing.

Rare Inherited and Targeted Oncology

  • Continued to advance our preclincial 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).
    • We have initiated 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.
    • Prior studies of erythromycin in APCMin mice showed reductions in colon polyps that successfully translated to demonstrating clinical efficacy.1
    • 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.
  • Initiated cancer cell line and xenograft mouse studies to evaluate the response to treatment with RMAs to advance first-in-class onco-ribosome targeted inhibitors for oncology therapy.


  • An underwritten public offering of 38,333,334 shares of common stock, including the full exercise of the underwriters’ option to purchase additional shares, at a public offering price of $1.35 per share was closed in May 2021. Aggregate gross proceeds from the offering were approximately $51.75 million, before deducting underwriting discounts and commissions and offering expenses.
  • Pedro Huertas, M.D., Ph.D., joined Eloxx as a Senior Adviser. Dr. Huertas previously served as CMO of Eloxx. He has also served as CMO of Inozyme Pharma and Sentien Biotechnologies and in various roles at Pfizer, Shire, Massachusetts General Hospital, and Genzyme.

Second Quarter 2021 Financial Results

For the three months ended June 30, 2021, we incurred a net loss of $36.1 million or $0.54 per share, which includes $4.0 million in stock-based compensation. For the same period in the prior year, we incurred a net loss of $7.9 million, or $0.20 per share. Results for the second quarter of 2021 included a $22.7 million acquired in-process research and development expense related to the acquisition of Zikani.

Our research and development expenses (R&D) were $5.7 million for the three months ended June 30, 2021, which includes $0.1 million in stock-based compensation. For the same period in the prior year, R&D expenses were $3.7 million. The increase in R&D expenses was primarily related to an increase in expenses related to the continued development of ELX-02 as a result of the suspension of our clinical trials due to the impact of the COVID-19 pandemic in the prior year period and an increase in salaries and other personnel related costs, partially offset by a decrease in stock-based compensation expense.

Our general and administrative (G&A) expenses were $7.4 million for the three months ended June 30, 2021, which includes $3.9 million in stock-based compensation. For the same period in the prior year, G&A expenses were $3.8 million. The increase was primarily related to an increase in stock-based compensation expense, an increase in salaries and other personnel-related costs associated with the merger with Zikani, as well as an increase in expenses attributable principally to infrastructure related costs including legal, accounting and other professional fees.

As of June 30, 2021, we had cash and cash equivalents of $56.7 million, which we expect will be sufficient to fund our operations into the first quarter of 2023.
