ImageneBio Reports Fourth Quarter and Full Year 2025 Financial Results and Provides Company Update

SAN DIEGO, March 10, 2026 — ImageneBio, Inc. (Nasdaq: IMA) (“Imagene” or the “Company”) today reported financial results for the fourth quarter and full year ended December 31, 2025, and provided a company update.

Company Highlights

• The IMG-007 Phase 2b ADAPTIVE trial in adults with moderate-to-severe atopic dermatitis (AD) is ongoing at North American sites; the study began enrolling in mid-2025 with topline data expected in 2027. A recent blinded safety review showed a favorable emerging tolerability profile consistent with previous IMG-007 patient experience.

• The Company has submitted a protocol amendment intended to expand the number and exposure range of dosing regimens being evaluated, characterize the role of loading doses, evaluate patient-friendly dosing intervals, and understand the effect of short- and longer-term treatment with IMG-007.

• The Company welcomed Dr. Ben Porter-Brown, who brings deep inflammation and medical dermatology experience including leading the development of anti-OX40L investigational therapeutic amlitelimab through the end of Phase 2, as Chief Medical Officer in February 2026.

• An oral presentation of IMG-007 preclinical data, including characterization of the non-depleting nature of the antibody, will be shared at the 83rd Annual Society for Investigative Dermatology (SID) Meeting (May 2026; Chicago, IL).

“IMG-007 is now the leading receptor-targeting OX40 antagonist program in clinical development. Our approach is entirely unlike that of ADCC-enhanced anti-OX40 antibodies such as rocatinlimab: published data has shown rocatinlimab treatment causes deep depletion of T cells, while IMG-007 is a non-T cell depleting antibody. This is a fundamental, intentional, and critical difference in our molecule’s design,” commented Kristin Yarema, PhD, Chief Executive Officer of Imagene. “While the clinical profile of IMG-007 remains early, our safety database continues to grow and we have not seen any of the tolerability issues mechanistically linked to T cell depletion — pyrexia, chills, ulcers — nor have we seen any malignancies. This emerging clinical profile adds to the compelling, competitive efficacy we saw in our proof-of-concept studies in atopic dermatitis and alopecia areata. We are confident that ADAPTIVE, our Phase 2b dose-ranging study in AD, is robust and designed to well characterize IMG-007’s efficacy, safety, and convenience for patients.”

IMG-007 Program Updates

IMG-007 is a novel, non-T cell depleting, receptor-targeting, anti-OX40 monoclonal antibody currently being evaluated in the Phase 2b ADAPTIVE trial in adults with moderate-to-severe AD. The study began enrolling in mid-2025 and is enrolling at North American sites.

• IMG-007 has been well tolerated in all clinical trials conducted to date, including in the ADAPTIVE trial. In total, over 150 subjects have participated in clinical trials of IMG-007, including several with six months or more continuous exposure.

• A blinded safety review was conducted in March 2026 to assess the consistency of IMG-007’s emerging tolerability profile

• A total of two serious adverse events, both deemed unrelated to IMG-007, have been observed to date across all studies of IMG-007, including in the ADAPTIVE Phase 2b trial

• Consistent with previous reporting, no cases of administration-associated pyrexia or chills, aphthous or gastrointestinal ulcers, serious infections or malignancies have been observed with IMG-007 treatment to date

• This includes no cases of Kaposi’s sarcoma

• Moreover, across all IMG-007 studies using the subcutaneous formulation to date, the rate of injection site reactions has been less than 0.10% with all reported events being mild and transitory

• The ADAPTIVE study is meeting enrollment expectations and, consistent with previous guidance, remains on track for a topline readout in 2027 with continued strong interest from investigators

• A previously announced protocol amendment to the ADAPTIVE trial was submitted with intent to:

• Expand the number and exposure range of dosing regimens studied to fully characterize the clinical profile of IMG-007

• Characterize the role of loading doses in driving the magnitude of efficacy and time to onset of effect

• Evaluate patient-friendly dosing intervals

• Understand the role of short- and longer-term treatment

• Optimize study execution

“It has been inspiring to hear the enthusiasm for IMG-007 from our investigators and other leading dermatologists, as well as their understanding of its unique features that we believe will prove key to establishing a differentiated efficacy, safety, and convenience profile.” said Dr. Ben Porter-Brown, Chief Medical Officer. ‘’We continue to have strong conviction that IMG-007 has the potential to be the most efficacious of this novel class of agents. While we advance the study, we are also mindful of recent news regarding competing Phase 3 development programs targeting OX40 or OX40L and the emerging focus on safety. Together with leaders in the field, we are actively exploring ways to better understand Kaposi’s sarcoma, its link with HHV-8 viral reactivation and any potential relationship to OX40-OX40L signaling in the AD patient population. As we apply these learnings to the IMG-007 program, our priority is to execute ADAPTIVE with rigor—and to continue to examine IMG-007’s novel profile, including safety, as well as the promising efficacy IMG-007 showed in proof-of-concept studies.”

Upcoming Scientific Presentation

Imagene will deliver an oral presentation of preclinical data, including characterization of IMG-007’s non-T cell depleting profile, at the 83rd Annual Society for Investigative Dermatology (SID) Meeting in May 2026 in Chicago, IL.

• Title: Preclinical characterization of IMG-007, a high-affinity, non-depleting anti-OX40 monoclonal antibody for the treatment of inflammatory and autoimmune disease

• Session: Translational Studies, Preclinical

• Date: May 15, 2026

Corporate Updates

In July 2025, ImageneBio, Inc. was formed and funded through a reverse merger with Ikena Oncology, Inc. (Ikena) and a concurrent $75 million private placement. The transaction followed a strategic process in which Ikena evaluated multiple companies and selected Imagene Biopharmaceuticals with the aim to fund and develop IMG-007.

In 2025 and early 2026, Imagene added several key executives, including Dr. Ben Porter-Brown as Chief Medical Officer, and an independent board member.

• Dr. Ben Porter-Brown joined Imagene with over 20 years of experience, primarily in autoimmune and inflammatory diseases. He most recently served as Chief Medical Officer of MoonLake Immunotherapeutics, and prior to that he spent several years at Kymab, Ltd, now a Sanofi Company, where as Vice President of Clinical Development he led the development of amlitelimab, an anti-OX40 ligand monoclonal antibody.

• Other 2025 team additions included:

• Kristin Yarema, Ph.D., Chief Executive Officer (July 2025)

• Kurinji Pandiyan, Ph.D., Chief Strategy and Operations Officer (September 2025)

• Renuka Sivendran, Ph.D., Chief Technical Officer (September 2025)

• Joe Slattery, independent Director and Chair of the Audit Committee (November 2025)

The Company ended 2025 with a strong financial position to execute on its Phase 2b clinical program in atopic dermatitis, with $135.3 million in cash, cash equivalents, and marketable securities as of December 31, 2025.

Fourth Quarter 2025 Financial Results

Cash Position: As of December 31, 2025, the Company had cash, cash equivalents, and marketable securities of $135.3 million as compared to $12.1 million as of December 31, 2024. The increase is primarily the result of the completion of the merger between Inmagene Biopharmaceutics with Ikena (the Merger). Additionally, concurrently with the closing of the Merger, the Company completed a $75.0 million private placement with a syndicate of existing Ikena investors and new investors.

Research and Development (R&D) Expenses: R&D expenses for the three months ended December 31, 2025 were $3.3 million as compared to $3.8 million for the three months ended December 31, 2024. The company continues to invest in clinical trial and personnel related expenses associated with its primary development program.

General and administrative (G&A) Expenses: G&A expenses for the three months ended December 31, 2025 were $5.2 million as compared to $2.4 million for the three months ended December 31, 2024. The increase of $2.8 million is primarily due to a $0.6 million increase in professional fees associated with the Merger and $1.8 million in personnel and non-cash stock-based compensation expenses.

Net Loss: Net loss for the three months ended December 31, 2025 was $6.9 million as compared to $4.8 million for the same period in 2024. The increase of $2.1 million was due to additional operating costs following the Merger and associated transaction costs.
