Finch Therapeutics Provides Corporate Updates and Reports Third Quarter 2022 Financial Results

• Patient dosing underway in PRISM4 Phase 3 trial of CP101 in recurrent CDI
  
  
• Topline PRISM4 data anticipated in H1 2024
• Anticipated cash runway into Q2 2024

SOMERVILLE, Mass., Nov. 10, 2022 (GLOBE NEWSWIRE) -- Finch Therapeutics Group, Inc. ("Finch" or "Finch Therapeutics") (NASDAQ:FNCH), a clinical-stage microbiome therapeutics company leveraging its Human-First Discovery® platform to develop a novel class of orally administered biological drugs, today provided corporate updates and reported financial results for the third quarter ended September 30, 2022.

"We are pleased with the tremendous progress our team has made recently to advance the development of our lead program, with patient dosing now underway in our PRISM4 Phase 3 trial of CP101, a product candidate that we believe holds the potential to fulfill the need for a convenient, one-time oral therapy to prevent recurrent C. difficile infection," said Mark Smith, PhD, Chief Executive Officer of Finch Therapeutics. "In an effort to accelerate our timeline to topline PRISM4 data and conserve capital, we are evaluating possible modifications to PRISM4 for future discussion with FDA, such as a reduction in the size of the randomized portion of the trial, an approach that may be informed in part by regulatory insights from the recent FDA advisory committee meeting for an enema-based microbiome product candidate. We look forward to providing additional updates as we continue to advance this important program."

Recent Program Highlights

• Proceeded with Patient Dosing in PRISM4 Recurrent CDI Trial, with Topline PRISM4 Data Anticipated in H1 2024: In October 2022, Finch announced that it had proceeded with patient dosing in PRISM4, a Phase 3 trial of CP101 for the prevention of recurrent C. difficile infection (CDI). The PRISM4 trial has two parts: a randomized, double-blind, placebo-controlled portion and an open-label portion for eligible participants who experience a recurrence during the randomized portion of PRISM4. Topline data from the randomized portion of PRISM4 is anticipated in the first half of 2024. To expand the safety database for CP101 in support of a potential Biologics License Application (BLA), Finch plans to allow direct entry into the open-label portion of PRISM4 following the completion of enrollment in the randomized portion of PRISM4.
  
  
  
  
• Presented CP101 PRISM-EXT Biomarker Data at ACG 2022: In October 2022, Finch announced the presentation of biomarker data from the PRISM-EXT open-label trial of CP101 in recurrent CDI at the American College of Gastroenterology (ACG) 2022 Annual Scientific Meeting. Following open-label administration of CP101 after standard-of-care (SOC) CDI antibiotics, there was a significant increase in microbiome diversity from baseline through week 8 and week 24 in PRISM-EXT participants. Higher engraftment of CP101-associated taxa and improvement in diversity were both associated with prevention of CDI recurrence through week 8 in PRISM-EXT participants. As previously reported, 80.3% and 78.8% of participants who received CP101 following SOC antibiotics in PRISM-EXT were without CDI recurrence through week 8 and week 24, respectively (n=132).
  
  
  
  
• Conducted Strategic Portfolio Review: Following a recent strategic review of its portfolio, which includes wholly-owned microbiome product candidates for recurrent CDI, inflammatory bowel disease (IBD) and autism spectrum disorder (ASD), Finch is prioritizing the development of CP101 in recurrent CDI and exploring opportunities to potentially advance the development of its pre-clinical candidates for IBD through strategic partnerships. In connection with the strategic review, Finch has suspended efforts to initiate a Phase 1 trial of FIN-211 in ASD while the Company explores opportunities to leverage clinical data generated by ongoing third-party studies to inform its autism program strategy going forward, as previously announced.

Recent Corporate Highlights

• Appointed Howard Franklin, MD, MBA, as Chief Medical Officer: Dr. Franklin, a general surgeon and biopharmaceutical executive with more than 20 years of experience spanning clinical practice, clinical development, medical affairs, regulatory strategy, and product commercialization, previously served as Interim Chief Medical Officer for Finch. Prior to Finch, Dr. Franklin served as Chief Medical Officer at Salix Pharmaceuticals, where he provided leadership and expertise to program teams focused on the development of GI therapeutics. Prior to Salix, he held leadership roles within early-stage biotechnology companies as well as large pharmaceutical companies, including Icon Bioscience, Oceana Therapeutics, The Medicines Company, and Esprit Pharma.

Third Quarter 2022 Financial Results

• Finch reported a net loss of $40.4 million for the third quarter of 2022, compared to a net loss of $10.0 million for the same period in 2021. The net loss was driven by a charge of $18.1 million for the full impairment of the Company's goodwill during the current quarter. Additionally, there was a decrease in revenue of $11.2 million due to changes under Finch's collaboration agreement with Takeda, including Takeda's election in August 2022 to terminate the agreement. Finch also reported an increase in restructuring expenses of $1.3 million quarter-over-quarter.
  
  
  
  
• Research and development (R&D) expenses were $11.9 million for the third quarter of 2022, compared to $15.5 million for the same period in 2021. The decrease in R&D expense was driven by a decrease in expenses related to the CP101 program, primarily due to a decrease in external clinical research organization costs, in addition to a decrease in IBD program expenses due to Takeda's election in August 2022 to terminate its collaboration agreement with Finch. Additionally, there was a decrease in expenses associated with both the hepatitis B (HBV) and ASD programs, due to the Company's decision to suspend its HBV program, announced on March 31, 2022, and its subsequent decision, announced on September 1, 2022, to suspend its Phase 1 clinical trial in ASD.
  
  
  
  
• General and administrative (G&A) expenses were $9.6 million for the third quarter of 2022, compared to $5.7 million for the same period in 2021. The increase in G&A expense was primarily due to an increase in professional fees, in addition to an increase in facility-related costs and stock-based compensation expense. This increase was partially offset by a decrease in employee-related expenses due to reduced headcount.
  
  
  
  
• Finch's cash and cash equivalents as of September 30, 2022 were $85.3 million, compared to $133.5 million as of December 31, 2021. Finch believes its cash and cash equivalents on hand as of September 30, 2022, together with anticipated cash inflows from executed subleases for one of the Company's office and lab facilities, will fund its operations into Q2 2024.

About the PRISM4 Phase 3 Trial

PRISM4 is a randomized, double-blind, placebo-controlled, multi-center Phase 3 trial evaluating the efficacy and safety of a one-time oral administration of CP101 for the prevention of recurrent C. difficile infection (CDI). After completing standard-of-care CDI antibiotics for their most recent CDI recurrence, eligible participants will be randomized in a 2:1 ratio to receive either CP101 or placebo. Participants will be evaluated for CDI recurrence and safety through week 8, the primary endpoint, as well as through week 24. Participants who qualify may enroll in the optional open label arm and receive CP101 if they experience a CDI recurrence through week 8 of the trial. To learn more about the trial, visit clinicaltrials.gov (Identifier: NCT05153499) or the study website at https://prism4trial.com/.
