Edesa Biotech Reports Fiscal 2nd Quarter 2025 Results

TORONTO, May 14, 2025 (GLOBE NEWSWIRE) -- Edesa Biotech, Inc. (Nasdaq:EDSA), a clinical-stage biopharmaceutical company focused on developing host-directed therapeutics for immuno-inflammatory diseases, today reported financial results for the three and six months ended March 31, 2025 and provided an update on its business.

During the quarter, the company completed a $15 million equity financing from healthcare-focused institutional investors, existing Edesa shareholders and insiders to support the development of the company’s vitiligo drug candidate EB06, anti-CXCL10 monoclonal antibody. The company has subsequently initiated outreach to potential investigators and manufacturing-related activities to support U.S. regulatory approval for a Phase 2 study in moderate-to-severe nonsegmental vitiligo patients.

“The initial steps in the manufacturing of our biological drug are ongoing and we are excited about the potential of a novel immunotherapy like EB06. Vitiligo significantly impacts the lives of millions worldwide, yet there are no approved drugs that address the systemic nature of the disease. We believe we can ultimately change the treatment paradigm in much the same manner that immunotherapies have transformed other systemic autoimmune diseases like psoriasis,” said Par Nijhawan, MD, Chief Executive Officer of Edesa Biotech.

Edesa's Chief Financial Officer Peter Weiler reported that financial results for the quarter reflected a pivot in operational activity to the company’s vitiligo development program, from its respiratory program. Increased expenditures for the EB06 program were offset by decreased expenses for the EB05 drug candidate as the company benefits from a fully funded government study investigating Edesa’s respiratory drug as a treatment for Acute Respiratory Distress Syndrome (ARDS).

“We are deploying additional resources to manufacturing and preparatory regulatory activities to speed the launch of our upcoming vitiligo study, and we anticipate that related research expenditures will generally track activity in this program,” Mr. Weiler said.

Based on the current availability of manufacturing slots at third party service providers, Edesa reported that the company anticipates drug manufacturing data to be submitted to the U.S. Food and Drug Administration (FDA) for its investigational new drug (IND) application in the second half of calendar 2025. Edesa anticipates topline results could be available within as few as 12 to 18 months following regulatory clearance by the FDA. The planned Phase 2 study is already approved in Canada.

Financial Results for the Three Months Ended March 31, 2025

Total operating expenses decreased by $0.6 million to $1.6 million for the three months ended March 31, 2025 compared to $2.2 million for the three months ended March 31, 2024:

• Research and development expenses decreased by $0.7 million to $0.5 million for the three months ended March 31, 2025 compared to $1.2 million for the same period last year primarily due to decreased external research expenses related to manufacturing the company’s investigational drug, paridiprubart, which were partially offset by an increase in EB06-related expenses for the planned Phase 2 vitiligo study.
  
  
• General and administrative expenses increased by $0.2 million to $1.2 million for the three months ended March 31, 2025 compared to $1.0 million for the same period last year primarily due to an increase in salaries and related costs, which were partially offset by a decrease in noncash share-based compensation and professional service fees.

Total other income decreased by $311,000 to $49,000 for the three months ended March 31, 2025 compared to $360,000 for the same period last year. This decrease was primarily due to a decrease in reimbursement funding from the Canadian government's Strategic Innovation Fund as well as a decrease in interest income.

For the quarter ended March 31, 2025, Edesa reported a net loss of $1.6 million, or $0.30 per common share, compared to a net loss of $1.9 million, or $0.58 per common share, for the quarter ended March 31, 2024.

Financial Results for the Six Months Ended March 31, 2025

Total operating expenses decreased by $0.6 million to $3.5 million for the six months ended March 31, 2025 compared to $4.1 million for the six months ended March 31, 2024:

• Research and development expenses decreased by $0.4 million to $1.5 million for the six months ended March 31, 2025 compared to $1.9 million for the same period last year primarily due to decreased external research expenses related to manufacturing the company’s investigational drug, paridiprubart, which were partially offset by an increase in EB06-related expenses for the planned Phase 2 vitiligo study.
  
  
• General and administrative expenses decreased by $0.2 million to $2.0 million for the six months ended March 31, 2025 compared to $2.2 million for the same period last year primarily due to a decrease in noncash share-based compensation and professional service fees, which were partially offset by an increase in salaries and related costs.
  

Total other income decreased by $208,000 to $331,000 for the six months ended March 31, 2025 compared to $539,000 for the same period last year, primarily due to a decrease in interest income as well as a decrease in reimbursement funding from the Canadian government's Strategic Innovation Fund.

For the six months ended March 31, 2025, Edesa reported a net loss of $3.2 million, or $0.74 per common share, compared to a net loss of $3.5 million, or $1.12 per common share, for the six months ended March 31, 2024.
