ImageneBio Reports Second Quarter 2026 Financial Results

SAN DIEGO, Aug. 5, 2026 (GLOBE NEWSWIRE) — ImageneBio, Inc. (Nasdaq: IMA) (“Imagene” or the “Company”) today reported financial results for the quarter ended June 30, 2026, and provided a company update.

Company Highlights

• Olevaprubart, also known as IMG-007, the potential first-in-class therapeutic targeting the OX40 pathway, is a non-T cell-depleting, ADCC-silenced, anti-OX40 receptor antagonist with an extended half-life.

• The Phase 2b ADAPTIVE trial of olevaprubart in moderate-to-severe atopic dermatitis continues to progress as planned under the amended protocol.

• A long-term extension (LTE) study has been opened for patients enrolled in ADAPTIVE and sites are actively enrolling patients into the extension protocol.

• A Phase 2 clinical trial of olevaprubart in alopecia areata is planned to initiate in 2026.

• The company will present two posters on olevaprubart at the 2026 European Academy of Dermatology and Venereology (EADV) Congress.

• Imagene strengthened its leadership team with the appointments of Yanina Grant-Huerta as Chief Financial Officer and Matt Robbins as General Counsel.

• $136.2 million in cash, cash equivalents and marketable securities as of June 30, 2026, providing anticipated funding for planned operations into the first quarter of 2028.

“Imagene’s olevaprubart is now primed to emerge as the leading OX40 signal blockade program. With our continued progress in advanced clinical development, our conviction remains strong,” said Kristin Yarema, Ph.D., chief executive officer of Imagene. “Olevaprubart was engineered to be a genuinely differentiated medicine with the potential for strong, competitive efficacy and a favorable safety profile. This is what our Phase 2b ADAPTIVE study is designed to evaluate and we are very pleased with our progress. Atopic dermatitis and alopecia areata remain areas of significant unmet need, and, as we are following every new development in the field closely, none of it changes what we believe: that direct, T cell-targeted yet non-T cell depleting approaches like ours have the potential to provide durable, safe and strong benefit for patients. Our programs remain on track and we continue to advance as planned, including welcoming patients who have completed a year of treatment into our long-term extension study.”

Recent Corporate Updates

• In April 2026, Imagene closed a $30 million private placement with participation from both new and current investors.

• In July 2026, Imagene appointed Yanina Grant-Huerta as Chief Financial Officer.

• Grant brings 20 years of financial and accounting leadership experience in the biopharma industry.

• She most recently served as Chief Accounting Officer at Atara Biotherapeutics and previously spent 14 years at Amgen Inc. in progressively senior finance and business analysis roles.

• Imagene also appointed Matt Robbins as General Counsel, bringing more than 15 years of corporate, securities, and transactional experience advising public and private life sciences companies.

• Dr. Ben Porter-Brown transitioned to a consulting role at the end of July 2026, continuing to support the Company as a consulting clinical development expert and strategic advisor.

Olevaprubart Program Updates

• Atopic Dermatitis: The previously announced protocol amendment to the ADAPTIVE trial has been implemented, and the study continues to progress under the amended protocol.

• The amended protocol introduces a robust design intended to further evaluate the potential of olevaprubart in moderate-to-severe atopic dermatitis.

• Topline data from the study is anticipated in the fourth quarter of 2027.

• A long-term extension study has been opened for those who have completed one year in the ADAPTIVE study (NCT07734415) and patients are actively moving into the LTE.

• The Independent Data Monitoring Committee (IDMC) for the ADAPTIVE study recommended the study proceed with no changes to the protocol or monitoring on July 23, 2026.

• As of July 31, 2026 no cases of Kaposi sarcoma have been observed across the olevaprubart program, including in ongoing studies.

• Alopecia Areata: Imagene remains on track to initiate a Phase 2 study of olevaprubart in alopecia areata in 2026.

• Initial data expected in 2028, leveraging the clinical operations and investigator network the Company has developed through its atopic dermatitis program.

• Upcoming Scientific Presentations: Imagene will present two posters at the 2026 European Academy of Dermatology and Venereology (EADV) Congress:

• Title: IMG-007, a non-depleting OX40 antagonist: Optimizing Peak Loading Concentration and Exposure Range to Unlock the Full Potential of OX40-OX40L Pathway Targeting in Immune Mediated Diseases

• Poster Number: P1683

About Olevaprubart (formerly IMG-007)

Olevaprubart (formerly IMG-007) is an investigational, non-T cell-depleting monoclonal antibody targeting OX40, a receptor protein primarily found on activated human T cells. When OX40 binds its ligand OX40L in human tissue, the signal generated plays a key role in the activation, expansion, and survival of many subtypes of T cells. Targeted inhibition of OX40 is being studied in the clinic across a range of autoimmune, inflammatory and immunological conditions where aberrant signaling of one or more T cell subtypes is believed to drive disease. Olevaprubart has been engineered to include a silenced antibody-dependent cell-mediated cytotoxicity function demonstrated to avoid T cell depletion or killing and intended to minimize safety risk. This technology also resulted in an approximately 5-week half-life, prolonging therapeutic activity with the aim of maximizing time between doses for a patient.

About ImageneBio, Inc.

Imagene has completed Phase 1b/2a clinical trials of olevaprubart in both atopic dermatitis and alopecia areata and is currently conducting a Phase 2b clinical trial of olevaprubart in patients with moderate-to-severe atopic dermatitis.
