WATERTOWN, Mass., March 31, 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 and year ended December 31, 2021 and provided a business update.
“The recently announced funding from the CF Foundation, together with positive topline clinical results from the monotherapy arm of Phase 2 of the ELX-02 clinical trial announced in November 2021, has increased our confidence in the potential of ELOX-02 to transform the lives of Class 1 CF patients with nonsense mutations,” said Sumit Aggarwal, President and Chief Executive Officer of Eloxx. “In addition to the ELOX-02 CF program, we believe we continue to make significant progress across our portfolio of product candidates. With the addition of a new program in Alport syndrome, a rare kidney disease, we believe we are beginning to fully capture the potential of ELX-02 as a novel readthrough agent while at the same time, our oral RMAs continue to advance forward with encouraging preclinical data in RDEB and FAP that demonstrate the potential of ribosome modulation.”
Fourth Quarter 2021 and Subsequent Highlights
Class 1 Cystic Fibrosis
- Eloxx recently announced additional funding from a Therapeutic Development Award of up to $15.9 million from the CF Foundation to support the ongoing global Phase 2 ELX-02 clinical development of ELX-02 in CF. This award is in addition to the previously announced partial funding of the global clinical trial program. Following an upfront funding of $7.0 million, the funding will be tranched based on the achievement of certain clinical milestones. Eloxx will pay the CF Foundation royalties tiered to the actual level of funding from the CF Foundation.
- Expansion arm of the ongoing Phase 2 clinical trials in CF patients affected by nonsense mutations in the CFTR (CF transmembrane conductance regulator) gene, which is designed to evaluate the safety of ELX-02 and assess short-term biological activity in patients, remains ongoing.
- In preclinical studies, Class 1 CF patient organoids had a 2- to 3-fold higher swelling response with a combination of ELX-02 and ivacaftor than with ELX-02 as a monotherapy.
- Topline results are expected by the end of the first half of 2022.
- Topline results from monotherapy arm of Phase 2 trials announced in November 2021. ELX-02 was well tolerated and achieved a statistically significant 5.4mmol/L reduction in sweat chloride in patients at the 1.5mg/kg/day dose.
- Evaluation of inhaled (nebulizer-based) delivery of the current subcutaneous formulation of ELX-02 remains ongoing. We believe 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. We expect to submit an Investigational New Drug (IND) application in the second half of 2022.
- As previously announced, the U.S. Food and Drug Administration (FDA) has granted Fast Track designation for ELX-02 for the treatment of CF patients with nonsense mutations. In addition, ELX-02 has also been granted Orphan Drug Designation for the treatment of CF patients with nonsense mutations by the FDA and orphan medicinal product designation by the European Commission.
Alport Syndrome
- Eloxx recently announced it has expanded the ELX-02 development pipeline to include the treatment of Alport syndrome, a rare kidney disease. Alport syndrome is a genetic disorder characterized by kidney disease with high levels of proteinuria, hearing loss and eye abnormalities caused by mutations in the genes (COL4A3, COL4A4, and COL4A5) needed for production of type 4 collagen.
- Eloxx believes there is a strong rationale to pursue clinical development of ELX-02 in Alport syndrome based on encouraging preclinical results demonstrating potentially therapeutic levels of readthrough, ability to deliver high drug concentrations in the kidney relative to plasma at clinically tolerable dose levels, and the clinical readthrough results seen in our Phase 2 cystic fibrosis trial.
- ELX-02 is preferentially taken up in the kidney, resulting in an expected greater than 50-fold exposure in the kidneys compared to plasma.
- In recently published preclinical studies, ELX-02 has demonstrated significant readthrough in COL4A5 mutations, which represent 85% of nonsense mutations in this population.
- Eloxx intends to initiate a proof-of-concept clinical trial in up to eight Alport syndrome patients with nonsense mutations in the second half of 2022. 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.
Recessive Dystrophic Epidermolysis Bullosa and Junctional Epidermolysis Bullosa (JEB)
- We believe Eloxx remains on track to file an IND application start a First in Human (FIH) Phase 1 study in 2022 with ZKN-013 based on continued preclinical validation of ability to induce functional full-length Collagen 7A in RDEB patient cells and encouraging safety results in recently completed non Good Laboratory Practice (GLP) animal studies.
- Eloxx has conducted additional preclinical studies of ZKN-013. These demonstrated that ZKN-013 induces the production of functional, full-length COL7 in RDEB patient cells at levels comparable to high dose gentamicin. Induction of readthrough in multiple cell types and mutations from ZKN-013 was confirmed by research labs at University of Southern California and the Thomas Jefferson University, widely recognized leaders in RDEB.
Familial Adenomatous Polyposis and Targeted Oncology
- Eloxx continues 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 most advanced program is for the treatment of patients with FAP with nonsense mutations. Eloxx has seen encouraging results for ZKN-013 in the APCMin (multiple intestinal neoplasia) model for treatment of patients with FAP for ZKN-013. Eloxx completed an 8-week treatment study in this model to evaluate the potential of ZKN-013 to treat FAP. The APCMin mouse is a translationally validated model for drug development for FAP.
- The study demonstrated a significant 50% reduction in polyp burden and a 40% reduction in the number of polyps in ZKN-013 treated mice, including substantial reductions in both lesion area and area of adenoma with no progression to carcinomas. This led to an observed 50% survival benefit. These results compare favorably with treatment results with Celecoxib.
- Cancer cell line and xenograft mouse studies ongoing to evaluate the response to treatment with RMAs to advance onco-ribosome targeted inhibitors for oncology therapy.
Corporate Update
- In September 2021, 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, comprised of three tranches. On September 30, 2021, Eloxx drew the initial tranche of $12.5 million and used the proceeds to repay in full amounts outstanding under the Eloxx’ existing debt facility with Silicon Valley Bank. The remaining tranches under the new facility will be available to Eloxx based on achieving certain clinical and equity milestones during defined time periods.
Fourth Quarter 2021 Financial Results
For the three months ended December 31, 2021, we incurred a net loss of $12.1 million, or $0.14 per share, which includes $1.6 million in stock-based compensation. For the same period in the prior year, we incurred a net loss of $6.1 million, or $0.15 per share. Since the closing date of Eloxx’s acquisition of Zikani Therapeutics, Inc. in April 2021, the results of Zikani’s operations have been included in the Eloxx’ condensed consolidated financial statements.
Our research and development expenses (R&D) were $7.9 million for the three months ended December 31, 2021, which includes $0.6 million in stock-based compensation. For the same period in the prior year, R&D expenses were $2.6 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 $3.7 million for the three months ended December 31, 2021, which includes $1.0 million in stock-based compensation. For the same period in the prior year, G&A expenses were $3.1 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 December 31, 2021, we had cash and cash equivalents of $42.3 million, which combined with $7.0 million from the CF Foundation, we expect will be sufficient to fund our operations into the second quarter of 2023.
About Nonsense Mutations
Nonsense mutations cause a premature stop codon in the mRNA resulting in less than full length or loss of function proteins. These remain highly underserved with no approved disease modifying therapies. An estimated 10-12% patients across over 8,000 inherited genetic rare diseases harbor nonsense mutations in one or both alleles harboring nonsense mutations.
