Item 7.01. Regulation FD Disclosure.
On October 3, 2024, Theriva Biologics, Inc. (the “Company”) issued a press release announcing a positive outcome from the Data and Safety Monitoring Committee (“DSMC”) review of results from the second Cohort of the Company’s Phase 1b/2a randomized, double-blinded, placebo-controlled clinical trial of SYN-004 (ribaxamase) in allogeneic hematopoietic cell transplant (“HCT”) recipients for the prevention of acute graft-versus-host-disease.
Based on a review of the safety and pharmacokinetic data, the DSMC has recommended that the study may proceed to enroll Cohort 3 in which study drug (SYN-004 or Placebo) will be administered in combination with the IV beta-lactam antibiotic cefepime. The Company is pursuing additional funding to enable the conduct of the third cohort
The Phase 1b/2a study is on-going and remains blinded; however, key findings from blinded data for Cohort 2 are included below:
| · | Adverse events (“AEs”) and serious adverse events (“SAEs”) observed in Cohort 2 were typical of those observed in allo-HCT patients and no AEs or SAEs were determined by the investigators to be related to study drug treatment. |
| o | A total of 15 SAEs were reported among 10 patients, with the most common SAE being infections and infestations, including sepsis. |
| o | No patients died within the 30-day follow-up period after the last dose of study drug; 1 patient died 95 days and another 211 days after the last dose of study drug due to cancer relapse and pneumonia respectively (not related to study drug). |
| · | Consistent with the findings from Cohort 1 and previous studies of SYN-004 in healthy volunteers, no patient blood samples were positive for SYN-004 at any timepoint. |
| · | The pharmacokinetics of piperacillin, which can be metabolized by SYN-004, were as expected for this patient population. |
The information in this Item 7.01 and in the press release furnished as Exhibit 99.1 to this Current Report on Form 8-K shall not be deemed to be “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended, or otherwise subject to the liabilities of that section or Sections 11 and 12(a)(2) of the Securities Act of 1933, as amended and shall not be incorporated by reference into any filing with the U.S. Securities and Exchange Commission made by the Company, whether made before or after the date hereof, regardless of any general incorporation language in such filing. The press release furnished as Exhibit 99.1 to this Current Report on Form 8-K includes “safe harbor” language pursuant to the Private Securities Litigation Reform Act of 1995, as amended, indicating that certain statements contained therein are “forward-looking” rather than historical.
