Item 8.01. Other Events.

On October 15, 2026, Edesa Biotech, Inc. (the

“Company”) reported that the U.S. Food and Drug Administration (“FDA”) has cleared the Company's Investigational

New Drug (“IND”) application for its Phase 2 clinical study of EB06 in vitiligo, enabling the Company to expand recruitment

to the United States. Patient recruitment is underway in Canada and the first U.S. investigational sites are expected to begin enrolling

subjects next quarter. The Company anticipates that topline data will be available fourth quarter 2027.

The double-blind, placebo-controlled clinical

study is evaluating EB06, a monoclonal antibody targeting CXCL10, in up to 80 adults with moderate-to-severe nonsegmental vitiligo. Participants

are randomized 1:1 to receive either EB06 or placebo every two weeks through Week 22. The primary efficacy endpoint is the mean percent

change from baseline in the Facial Vitiligo Area Scoring Index (F-VASI) at Week 28. Secondary and exploratory measures include facial

and total-body scoring benchmarks, as well as assessments of safety, tolerability, pharmacokinetics and immunogenicity.

EB06 is a fully human monoclonal antibody targeting

CXCL10, a signaling protein implicated in vitiligo. By inhibiting CXCL10, EB06 is designed to interrupt immune-cell recruitment and melanocyte

loss through a targeted mechanism that is distinct from broader immunomodulatory approaches. The safety and efficacy of EB06 remain subject

to clinical evaluation.

Cautionary Language Concerning Forward-Looking

Statements

Statements contained in this Current Report on

Form 8-K regarding matters that are not historical facts are “forward-looking statements” within the meaning of the Private

Securities Litigation Reform Act of 1995. These forward-looking statements are made on the basis of the current beliefs, expectations

and assumptions of management, are not guarantees of performance and are subject to significant risks and uncertainty. These forward-looking

statements should, therefore, be considered in light of various important factors, including those set forth in the Company’s reports

that it files from time to time with the Securities and Exchange Commission and which you should review, including those statements under

“Item 1A. Risk Factors” in the Company’s Annual Report on Form 10-K for the year ended September 30, 2025.

Because forward-looking statements are subject

to risks and uncertainties, actual results may differ materially from those expressed or implied by such forward-looking statements. Such

statements include, but are not limited to, statements regarding the timing and success of the Company’s clinical trials and regulatory

approvals.

These forward-looking statements should not be

relied upon as predictions of future events and the Company cannot assure you that the events or circumstances discussed or reflected

in these statements will be achieved or will occur. If such forward-looking statements prove to be inaccurate, the inaccuracy may be material.

You should not regard these statements as a representation or warranty by the Company or any other person that the Company will achieve

its objectives and plans in any specified timeframe, or at all. You are cautioned not to place undue reliance on these forward-looking

statements, which speak only as of the date of this filing. The Company disclaims any obligation to publicly update or release any revisions

to these forward-looking statements, whether as a result of new information, future events or otherwise, after the date of this filing

or to reflect the occurrence of unanticipated events, except as required by law.
