Synthetic Biologics Reports Third Quarter 2021 Operational Highlights and Financial Results; Conference Call to be Held Today at 4:30 PM ET

ROCKVILLE, Md., Nov. 3, 2021 /PRNewswire/ -- Synthetic Biologics, Inc. (NYSE American: SYN), a diversified clinical-stage company leveraging the microbiome to develop therapeutics designed to prevent and treat gastrointestinal ("GI") diseases in areas of high unmet need, today provided a clinical programs update and reported financial results for the third quarter ended September 30, 2021.

Recent Developments:

• Initiated a Phase 1, placebo-controlled, multiple ascending dose clinical study of SYN-020 intestinal alkaline phosphatase ("IAP")
• Continuing enrollment in the Phase 1b/2a clinical trial of SYN-004 (ribaxamase) in allogeneic hematopoietic cell transplant ("HCT") recipients
• Current cash position of approximately $72.1 million
• Current cash runway expected to provide funding to complete Phase 1b/2a clinical trial of SYN-004, clinical trials of SYN-020 through proof-of-concept, and other key milestones into 2023

Anticipated Milestones:

• Topline data readout from the first antibiotic cohort of the SYN-004 Phase 1b/2a clinical trial is expected during Q1 2022
• Expect to announce topline data readout from the Company's Phase 1 MAD clinical trial of SYN-020 during Q2 2022

"During the third quarter, we significantly advanced our portfolio of GI and microbiome-focused clinical programs," said Steven A. Shallcross, Chief Executive Officer of Synthetic Biologics. "We were pleased to initiate a Phase 1 multiple ascending dose clinical trial of our SYN-020 IAP program during the third quarter of 2021. At this time, the first cohort of 8 study participants is nearing completion with dosing of the second cohort of 8 study participants expected to begin shortly thereafter, pending a safety review. We anticipate reporting topline data from this clinical trial during the second quarter of 2022. This study follows our recent Phase 1 single ascending dose ("SAD") clinical trial of SYN-020, in which SYN-020 was well tolerated and demonstrated a favorable safety profile at all doses. Both clinical trials are designed to support the advancement of SYN-020 in multiple potential therapeutic indications, including radiation enteropathy, celiac disease, non-alcoholic fatty liver disease (NAFLD), and age-related metabolic and inflammatory diseases. We continue to view SYN-020 as a multi-indication platform program, which has the potential to help address a considerable need for innovative new therapies targeting disorders that stem from immune and inflammatory damage to the intestine."

Mr. Shallcross continued, "We also continue to progress the SYN-004 Phase 1b/2a clinical trial in allogeneic hematopoietic cell transplant ("HCT") recipients. Patient screening and enrollment is ongoing at the Washington University School of Medicine in St. Louis ("Washington University"). As a result, we currently anticipate announcing topline results from the first of three antibiotic cohorts during the first quarter of 2022. We believe SYN-004 has the potential to address a significant unmet medical need by improving outcomes for allogeneic HCT recipients. Overall, we remain very excited about the potential for each of our clinical programs and near-term clinical milestones that we believe could drive significant value for shareholders."

Clinical Development and Operational Update 

• Announced commencement of the Company's Phase 1, placebo-controlled, multiple ascending dose clinical trial of SYN-020
• The ongoing Phase 1 MAD clinical trial is intended to evaluate the safety, tolerability and biodistribution of SYN-020 upon repeated dosing in up to 32 healthy adult volunteers.
• The study is divided into 4 sequential cohorts of 8 participants, with SYN-020 (5 mg, 15, mg, 45 mg or 75 mg) given orally twice daily for 14 days.
• At this time, the first cohort of 8 study participants is nearing completion and dosing of the second cohort of 8 study participants is expected to begin shortly thereafter, pending a safety review.
• A safety review will be conducted at the end of each cohort to determine whether progression to the next higher dose cohort is permissible.
• A topline data readout from this clinical trial is anticipated during the second quarter of 2022, pandemic conditions permitting.
• A previously completed Phase 1 single ascending dose clinical study of SYN-020 enrolled 24 healthy adult volunteers into four cohorts with SYN-020 given orally as a single dose ranging from 5 mg to 150 mg. Analyses of preliminary data demonstrated that SYN-020 maintained a favorable safety profile, was well tolerated at all dose levels, and no adverse events were attributed to study drug. No serious adverse events were reported.
• Both studies are intended to support the development of SYN-020 in multiple potential clinical indications including radiation enteropathy, celiac disease, NAFLD, as well as indications supported by the Company's collaboration with Massachusetts General Hospital.
• Enrollment in the Company's Phase 1b/2a clinical trial of SYN-004 in allogeneic HCT recipients for the prevention of acute graft-versus-host-disease ("aGVHD") remains ongoing
• The Phase 1b/2a clinical trial comprises a single center, randomized, double-blind, placebo-controlled clinical trial of oral SYN-004 in up to 36 evaluable adult allogeneic HCT recipients.
• The goal of this clinical trial is to evaluate the safety, tolerability, and potential absorption into the systemic circulation (if any) of oral SYN-004 administered to allogeneic HCT recipients who receive an IV beta-lactam antibiotic to treat fever.
• Study participants will be enrolled into three sequential cohorts and administered a different study-assigned IV beta-lactam antibiotic. Eight participants in each cohort will receive SYN-004 and 4 will receive placebo.
• Safety and pharmacokinetic data for each cohort will be reviewed by an independent Data and Safety Monitoring Committee ("DSMC"), which will make a recommendation on whether to proceed to the next IV beta-lactam antibiotic.
• A topline data readout for the first of three antibiotic cohorts is anticipated during the first quarter of 2022, pandemic conditions permitting.

Quarter Ended September 30, 2021 Financial Results

General and administrative expenses increased by 9% to approximately $1.3 million for the three months ended September 30, 2021, from approximately $1.2 million for the three months ended September 30, 2020. This increase is primarily due to higher insurance costs, audit fees and registration fees offset by lower legal costs and vacation expense. The charge related to stock-based compensation expense was $83,000 for the three months ended September 30, 2021, compared to $67,000 for the three months ended September 30, 2020.

Research and development expenses increased by 116% to approximately $2.0 million for the three months ended September 30, 2021, from approximately $900,000 for the three months ended September 30, 2020. This increase is primarily the result of increased clinical trial expenses as we continued dosing patients in the Phase 1b/2a clinical trial of SYN-004 and by higher indirect program costs for the three months ended September 30, 2021, including an increase in manufacturing costs for SYN-020. We anticipate research and development expense to increase as our ongoing clinical trials continue to enroll patients. The charge related to stock-based compensation expense was $19,000 for the three months ended September 30, 2021, compared to $15,000 related to stock-based compensation expense for the three months ended September 30, 2020.

Other income was $2,000 for the three months ended September 30, 2021, compared to other income of $134 for the three months ended September 30, 2020. Other income for the three months ended September 30, 2021 and 2020 is primarily comprised of interest income.

Cash and cash equivalents as of September 30, 2021 totaled $72.1 million, an increase of $65.9 million from December 31, 2020.
