Item 7.01 Regulation FD Disclosure.

On September 14, 2022, Eloxx Pharmaceuticals, Inc. (the “Company”) issued a press release announcing topline results from its Phase 2 combination clinical trial of ELX-02 in Class 1 Cystic Fibrosis (“CF”) patients. A copy of the press release and presentation are attached hereto as Exhibit 99.1 and Exhibit 99.2, respectively, and incorporated under this Item 7.01 by reference.

The information in this Item 7.01 of this Current Report on Form 8-K (including Exhibits 99.1 and 99.2 hereto) shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that Section, nor shall it be deemed to be incorporated by reference into any filing of the Company under the Securities Act of 1933, as amended, or the Exchange Act, except as expressly set forth by specific reference in such filing.

Item 8.01 Other Events

We are providing the following business update.

Recent Developments

On September 14, 2022, the Company announced topline results from the Phase 2 clinical trial of ELX-02 in combination with ivacaftor in Class 1 CF patients with at least one nonsense mutation. The combination trial of ELX-02 with ivacaftor was well tolerated but did not achieve statistical significance for efficacy endpoints, including changes from baseline in sweat chloride concentration (SCC) and percent forced expiratory volume (FEV1).

The Phase 2 combination clinical trial of ELX-02 was designed to evaluate safety and assess biological activity in G542X nonsense mutation Class 1 CF patients as monotherapy and in combination with ivacaftor. The trial included a 1-week monotherapy period (1.5 mg/kg daily subcutaneous) followed by a four week combination period (1.5 mg/kg daily subcutaneous and 150 mg ivacaftor twice daily).

ELX-02 was generally well tolerated in the trial, with no treatment-related serious adverse events noted. Overall, the study did not achieve statistical significance for efficacy endpoints in the Phase 2 study in Class 1 CF for efficacy endpoints, including changes from baseline in SCC and FEV1. No incremental improvement was observed with ivacaftor combination. Evidence of activity for ELX-02 was observed, as patients with higher baseline sweat chloride levels demonstrated increased responses as indicated by SCC (p=0.00013 at Day 35). Trial results were potentially confounded by high variability in sweat chloride and lung function measurement. The Company believes this variability could have been caused by very low drug exposures in the lung. Steady state lung drug levels in patients from this trial were on average 20%, or 2µM, of the lowest levels at which drug activity has previously been seen in preclinical testing. Lung drug exposure with inhaled delivery of ELX-02 is expected to be at least 50-fold greater than with subcutaneous delivery.

Eloxx Pharmaceuticals Reports Topline Results from Phase 2 Combination Clinical Trial of ELX-02 in Class 1 Cystic Fibrosis (CF) Patients

Combination of subcutaneous ELX-02 with ivacaftor did not achieve statistical significance for efficacy endpoints in Phase 2 study in Class 1 CF

ELX-02 was well tolerated with no drug-related serious adverse events observed

Evidence of activity for ELX-02 observed; efficacy signal potentially confounded by variability due to low drug exposure

Path forward for ELX-02 for the treatment of Class 1 CF to be determined together with CF Foundation

Company to host conference call and webcast today, September 14, 2022, at 4:30 p.m. ET

WATERTOWN, MA – September 14, 2022 – Eloxx Pharmaceuticals, Inc. (NASDAQ: ELOX), a leader in ribosomal RNA-targeted genetic therapies for rare diseases, today announced topline results from the Phase 2 clinical trial of ELX-02 in combination with ivacaftor in Class 1 cystic fibrosis (CF) patients with at least one nonsense mutation. The combination trial of ELX-02 with ivacaftor was well tolerated but did not achieve statistical significance for efficacy endpoints, including changes from baseline in sweat chloride concentration (SCC) and percent forced expiratory volume (FEV1).

“We are disappointed that ELX-02 failed to achieve statistical significance for its key efficacy endpoints in this Phase 2 trial in combination with ivacaftor for the treatment of Class 1 CF. Despite this setback, we were pleased to observe that ELX-02 was well tolerated and demonstrated additional evidence of activity in this underserved patient population. We will work closely with the CF Foundation, as it has generously supported this trial, to determine the next steps in the development of ELX-02 for CF,” said Sumit Aggarwal, President and Chief Executive Officer of Eloxx.

Mr. Aggarwal continued, “Given the safety and evidence of activity we have observed to date with ELX-02, including in this trial, we look forward to initiating a proof-of-concept trial for ELX-02 in Alport syndrome, a rare kidney disease, later this year. Given the likelihood of increased drug exposure, as ELX-02 is preferentially taken up in the kidneys, we believe ELX-02 is well suited to potentially deliver transformative results in these patients.”

 

Topline Results of ELX-02 Phase 2 Combination Trial in Class 1 CF Patients

The Phase 2 combination clinical trial of ELX-02 was designed to evaluate safety and assess biological activity in G542X nonsense mutation Class 1 CF patients as monotherapy and in combination with ivacaftor. The trial included a 1-week monotherapy period (1.5 mg/kg daily subcutaneous) followed by a four week combination period (1.5 mg/kg daily subcutaneous and 150 mg ivacaftor twice daily). Topline results are summarized below:

· ELX-02 was generally well tolerated in the trial, with no treatment-related serious adverse events noted.

· Overall, the study did not achieve statistical significance for efficacy endpoints in the Phase 2 study in Class 1 CF for efficacy endpoints, including changes from baseline in SCC and FEV1.

o No incremental improvement was observed with ivacaftor combination.

· Evidence of activity for ELX-02 was observed, as patients with higher baseline sweat chloride levels demonstrated increased responses as indicated by SCC (p=0.00013 at Day 35).

· Trial results were potentially confounded by high variability in sweat chloride and lung function measurement.

· Eloxx believes this variability could have been caused by very low drug exposures in the lung. Steady state lung drug levels in patients from this trial were on average 20%, or 2mM, of the lowest levels at which drug activity has previously been seen in preclinical testing.

o Lung drug exposure with inhaled delivery of ELX-02 expected to be at least 50-fold greater than with subcutaneous delivery.

About Class 1 CF

CF patients with a Class 1 nonsense mutation remain highly underserved with no approved disease modifying therapies. An estimated 10-12% of CF patients are Class 1 patients with one or both alleles harboring nonsense mutations, leading to less than full length CFTR proteins on the cell membrane in these patients.

Conference Call and Webcast

Eloxx’s management will host a conference call and webcast today at 4:30 p.m. ET. A live webcast of the conference call can be accessed through the “Investors” tab on the Eloxx website, and a replay will be available online after the call.
