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


Cystic Fibrosis Foundation (CF Foundation) awarded up to $15.9 million for the ongoing ELX-02 clinical program


Topline data from cystic fibrosis (CF) Phase 2 expansion treatment arms evaluating combination with ivacaftor expected at the end of the first half of 2022


Expanded development of ELX-02 for the treatment of Alport syndrome, a rare kidney genetic disorder, with Phase 2 expected to start in second half of 2022


Expect to submit an Investigational New Drug (IND) application for the inhaled delivery of ELX-02 in the second half of 2022


On track to start First in Human Phase 1 study in 2022 with ZKN-013 for the treatment of recessive dystrophic epidermolysis bullosa (RDEB) patients with nonsense mutations cells


Cash and equivalents expected to be sufficient to fund operations into the second quarter of 2023 


WATERTOWN, MA – May 10, 2022 – 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, 2022 and provided a business update.


“During the first quarter, we made significant progress, highlighted by the funding award from the CF Foundation and the expansion of our development program for ELX-02 in Alport syndrome, as we begin to fully capture the potential of ELX-02 as a novel readthrough agent,” said Sumit Aggarwal, President and Chief Executive Officer of Eloxx. “Combined with the continuing progress for our novel Ribosome Modulating Agents in RDEB and familial adenomatous polyposis, we believe we are poised to deliver on multiple potential value-creating events over the next twelve months.”





First Quarter 2022 and Subsequent Highlights


Class 1 Cystic Fibrosis


·In March 2022, Eloxx 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 Class 1 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.


·Phase 2 clinical trial in Class 1 CF patients, with expansion treatment arms, designed to evaluate the safety and assess short-term biological activity of ELX-02 in combination with Kalydeco, remains ongoing. Topline results are expected at the end of the first half of 2022.


·Evaluation of inhaled (nebulizer-based) delivery of the current subcutaneous formulation of ELX-02 remains ongoing. We believe that the increased drug exposure in the lung versus plasma with inhaled delivery has the potential to further improve the readthough activity of ELX-02. We remain on track to submit an Investigational New Drug (IND) application in the second half of 2022.


Alport Syndrome


·In March 2022, Eloxx announced it expanded its clinical development pipeline to include the potential treatment with ELX-02 of a subset of Alport syndrome patients with nonsense mutations in the Collagen Type 4 genes (COL4A3, COL4A4, and COL4A5). Alport syndrome is a rare genetic genetic kidney disorder characterized by high levels of proteinuria, hearing loss and eye abnormalities.


·Eloxx believes there is a strong rationale to pursue clinical development of ELX-02 in Alport syndrome based on encouraging preclinical results and clinical results


oClinical readthrough results in our Phase 2 cystic fibrosis trial at well tolerated dose levels confirm activity of ELX-02 to restore proteins


oIn recently published preclinical studies, ELX-02 has demonstrated significant readthrough in COL4A5 mutations, which represent 85% of nonsense mutations in this population. Previously published in vivo studies have shown that even low levels of Collagen IV restoration may result in significant reduction in proteinuria


oELX-02 is preferentially taken up in the kidney with an expected greater than 50-fold exposure in the kidneys compared to plasma. As a result, we expect that a low dose of 0.75mg/kg/day of ELX-02 could restore therapeutically relevant levels of Collagen IV.




·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)


·ZKN-013 continues to demonstrate dose dependent inducement of functional Collagen VIIA protein (truncated in patients with nonsense mutations patients), in RDEB patient cells.


·Eloxx expects to file an IND application to start a First in Human (FIH) Phase 1 study in 2022 with ZKN-013 after recently completing 28-day non Good Laboratory Practice (GLP) animal studies.


Familial Adenomatous Polyposis


·FAP is a rare inherited disease, with no approved drug therapies, characterized by proliferation of colon polyps. Eloxx is targeting a subset of patients that have nonsense mutations in the Adenomatous Polyposis Coli (APC) gene that is truncated in these patients.


·As previously announced, Eloxx observed encouraging results from an 8-week treatment study for ZNK-013 in the APCMin (multiple intestinal neoplasia) model to evaluate the potential of ZKN-013 to treat FAP. The APCMin mouse is a translationally validated model for drug development for FAP.


o10-week old APCMin mice were randomized for treatment with ZKN-013 for 8 weeks (n=10 in each group)


oTreatment with ZKN-013 resulted in a significant 39% reduction in the number of colon polyps and an approximately 50% reduction in polyp burden. There were substantial reductions in both lesion area and area of adenoma with no progression to carcinomas


oThis led to an observed 50% survival benefit with no deaths in mice treated with ZKN-013.





First Quarter 2022 Financial Results


For the three months ended March 31, 2022, we incurred a net loss of $11.6 million, or $0.13 per share, which included $0.9 million in stock-based compensation. For the same period in the prior year, we incurred a net loss of $8.7 million, or $0.22 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 March 31, 2022, which includes $0.4 million in stock-based compensation. For the same period in the prior year, R&D expenses were $4.1 million. The increase was primarily related to increases in expenses related to preclinical activities, the continued development of ELX-02, salaries and other personnel related costs, stock-based compensation and operational facilities.


Our general and administrative (G&A) expenses were $3.1 million for the three months ended March 31, 2022, which includes $0.6 million in stock-based compensation. For the same period in the prior year, G&A expenses were $4.3 million. The decrease was primarily related to decreases in salaries and other personnel related costs, stock-based compensation expense, consultant and professional fees, and operational facilities.


As of March 31, 2022, we had cash and cash equivalents of $39.8 million (inclusive of the $7.0 million from the CF Foundation), which 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.


About Eloxx Pharmaceuticals


Eloxx Pharmaceuticals, Inc. is engaged in the science of ribosome modulation, leveraging its innovative TURBO-ZMTM chemistry technology platform in an effort to develop novel Ribosome Modulating Agents (RMAs) and its library of Eukaryotic Ribosome Selective Glycosides (ERSGs). Eloxx’s lead investigational product candidate, ELX-02, is a small molecule drug candidate designed to restore production of full-length functional proteins. 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. ELX-02 is in clinical development, focusing on cystic fibrosis (US Trial NCT04135495, EU/IL Trial NCT04126473). Eloxx also has preclinical programs focused on select rare diseases, including inherited diseases, cancer caused by nonsense mutations, kidney diseases, including autosomal dominant polycystic kidney disease, as well as rare ocular genetic disorders.
