Edesa Biotech Reports Fiscal 3rd Quarter 2025 Results

TORONTO, Aug. 08, 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 nine months ended June 30, 2025 and provided an update on its business.

During the quarter, the company advanced manufacturing-related activities to support U.S. regulatory approval of a Phase 2 study of Edesa’s drug candidate EB06 (an anti-CXCL10 monoclonal antibody) in patients with moderate-to-severe nonsegmental vitiligo. Edesa anticipates drug manufacturing data for EB06 to be submitted to the U.S. Food and Drug Administration (FDA) for its investigational new drug (IND) application by the end of calendar 2025 based on the current availability of manufacturing slots at third party service providers.

“Our manufacturing plans are moving forward, and we’re energized by the opportunity to bring an innovative immunotherapy like EB06 into an area of high unmet need,” said Par Nijhawan, MD, Chief Executive Officer of Edesa Biotech. “We believe that the favorable safety profile of EB06, and its ability to target the immune system mechanisms impacting both lesional and non-lesional skin, has the potential to make it a preferable option for vitiligo patients – especially for those with lesions on more than 10% of their body surface area or those patients concerned about the safety risks of other treatments.”

Edesa's Chief Financial Officer Peter Weiler reported that financial results for the quarter and fiscal year-to-date were in line with management expectations and continued to reflect the refocusing of company resources to its vitiligo development program. He noted that increased expenditures for Edesa’s EB06 program were offset by decreased expenses for its EB05 drug candidate as the company benefits from the fully funded U.S. government “Just Breathe” study of EB05 and other host-directed therapeutics in a general ARDS patient population. During the quarter, the government announced that the first randomizations for the platform study were completed.

“We are channeling our operational efforts into regulatory preparation and drug manufacturing of our EB06 candidate with the goal of being in a position to move rapidly into clinical testing,” Mr. Weiler said.

Financial Results for the Three Months Ended June 30, 2025

Total operating expenses for each of the three months ended June 30, 2025 and June 30, 2024 were $1.9 million:

• Research and development expenses were $0.9 million for each of the three months ended June 30, 2025 and June 30, 2024, as an increase in EB06-related expenses for Edesa’s planned Phase 2 vitiligo study was offset by a decrease in external research expenses related to the company’s investigational respiratory drug, EB05 (paridiprubart).

• General and administrative expenses were $1.0 million for each of the three months ended June 30, 2025 and June 30, 2024, as a decrease in salaries and related costs was offset by an increase in noncash share-based compensation and professional service fees.
  
  

Total other income decreased by $110,000 to $154,000 for the three months ended June 30, 2025 compared to $264,000 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 June 30, 2025, Edesa reported a net loss of $1.7 million, or $0.25 per common share, compared to a net loss of $1.7 million, or $0.52 per common share, for the quarter ended June 30, 2024.

Financial Results for the Nine Months Ended June 30, 2025

Total operating expenses decreased by $0.6 million to $5.4 million for the nine months ended June 30, 2025 compared to $6.0 million for the nine months ended June 30, 2024:

• Research and development expenses decreased by $0.4 million to $2.4 million for the nine months ended June 30, 2025 compared to $2.8 million for the same period last year primarily due to a decrease in external research expenses related to EB05 (paridiprubart), which was partially offset by an increase in EB06-related expenses associated with preparations for the planned Phase 2 vitiligo study.

• General and administrative expenses decreased by $0.2 million to $3.0 million for the nine months ended June 30, 2025 compared to $3.2 million for the same period last year primarily due to a decrease in professional service fees and noncash share-based compensation.
  
  

Total other income decreased by $0.3 million to $0.5 million for the nine months ended June 30, 2025 compared to $0.8 million for the same period last year, 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 nine months ended June 30, 2025, Edesa reported a net loss of $5.0 million, or $0.95 per common share, compared to a net loss of $5.2 million, or $1.64 per common share, for the nine months ended June 30, 2024.
