Item 5.02 Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers. 

 

On September 8, 2026, the Board of Directors (the “Board”) of INmune Bio, Inc. (the “Company”) approved to increase the number of directors and to set the number of directors serving on the Board at seven, and, pursuant to the Company’s by-Laws, appointed R. Duane Clark II and James Sapirstein to serve as directors of the Company until the next annual election and until their successors are duly elected and qualified. The Board also appointed Mr. Clark and Mr. Sapirstein to serve as members of the Nominating and Corporate Governance Committee of the Board.

 

Mr. Clark, age 63, brings more than 40 years of global pharmaceutical and biotechnology leadership, with particular depth in rare diseases, immunology and specialty-product commercialization. He currently serves as General Manager, U.S. Rare Diseases at Sanofi, where he leads a multi-billion-dollar business spanning seven rare-disease brands with full profit-and-loss responsibility. His experience includes multiple product launches, market-access strategy, M&A integration, and leadership across sales, marketing, medical and commercial operations. Earlier in his career, he led Sanofi’s U.K. and Ireland multiple sclerosis business and held commercial and business-development roles at CTI Clinical Trial & Consulting Services, Encysive Pharmaceuticals, Astellas Pharma, Ortho Biotech and Marion Laboratories. Mr. Clark received a B.A. in Business and Marketing from University of Kentucky.

 

Mr. Sapirstein, age 65, brings more than 40 years of biopharmaceutical leadership spanning business development, licensing, commercialization, capital formation and public-company operating experience. He has led six global commercial product launches and participated in more than 20 additional launches. Mr. Sapirstein is currently the Chief Executive Officer of Cocrystal Pharma, Inc. (Nasdaq: COCP) and the Chief Executive Officer and Chairman of 8 Prime Biosciences, a private company. Prior to that, from October 2019 to February 2025, Mr. Sapirstein as Chief Executive Officer and Chairman of Entero Therapeutics, Inc. (Nasdaq: ENTO) (now known as GridAI Technologies Corp., Nasdaq:GRDX) and as a consultant from February 2025 to March 2026. His career includes senior roles at Gilead Sciences, Bristol Myers Squibb, Hoffmann-La Roche, Eli Lilly and Serono Laboratories. Mr. Sapirstein currently also serves as the Executive Chairman of Onconetix, Inc. (Nasdaq: ONCO) and as a director of ZyVersa Therapeutics, Inc (OTC Pink: ZVSA). He also founded and led Tobira Therapeutics which was later acquired by Allergan and has extensive experience structuring strategic transactions and guiding biotechnology companies through growth, restructuring and value-creating exits. Mr. Sapirstein received a B.S. in Pharmacy from Rutgers University and his MBA from Fairleigh Dickinson University.

 

The Board has determined that Mr. Clark and Mr. Sapirstein are both independent directors within the meaning of Nasdaq Listing Rule 5605. Mr. Clark qualifies to serve on the Board because of his extensive experience and leadership in the global pharmaceutical and biotechnology industries, with particular depth in rare diseases, immunology and specialty-product commercialization. Mr. Sapirstein qualifies to serve on the Board because of his extensive experience and leadership in the biopharmaceutical industry, which includes business development, licensing, commercialization, capital formation and public-company operating experience.

 

Mr. Clark and Mr. Sapirstein do not have a family relationship with any of the executive officers or directors of the Company. There are no arrangements or understandings between Mr. Clark and Mr. Sapirstein and any other persons pursuant to which they were selected as directors, and there are no transactions in which they have an interest requiring disclosure under Item 404(a) of Regulation S-K.
