His career is distinguished by his success in navigating complex regulatory landscapes and leading multiple high-value commercial launches. Notably, Mr. Handley has played a pivotal role in the US approval and commercialization of seventeen products, generating billions of dollars in revenue and providing life-altering treatments for tens of thousands of patients. His foundational expertise was developed at world-renowned organizations, including Amgen and Genentech.

A visionary leader, Mr. Handley is a passionate advocate for the development of innovative immunotherapies that utilize immune modulation as a cornerstone for disease mitigation and correction.

"Michael is a proven leader with an exceptional track record of building and scaling high-growth life sciences companies," said Sheryle Bolton, Chair of the Board of Tivic Health Systems. "As we transition toward late-stage immunotherapies and broader biopharma opportunities, his strategic vision and operational depth will be indispensable. On behalf of the Board, we extend our sincere appreciation to Jennifer Ernst for her dedicated leadership and meaningful contributions in positioning Tivic for its next phase of growth."

"I am honored to lead Tivic at this pivotal juncture," said Michael K. Handley, Chief Executive Officer. "We are entering a transformative new era for the Company, focused on high-growth biopharma opportunities and late-stage assets, such as Entolimod. By leveraging our foundational strengths and integrating advanced biomanufacturing through Velocity Bioworks, we are positioned to deliver profound value to patients and stakeholders alike."

"I am incredibly proud of what we've accomplished together in transforming this company and positioning it for growth," said Jennifer Ernst.
