ROCKVILLE, Md., Dec. 11, 2023 (GLOBE NEWSWIRE) -- MaxCyte, Inc., (NASDAQ: MXCT; LSE: MXCT), a leading, cell-engineering focused company providing enabling platform technologies to advance the discovery, development and commercialization of next-generation cell therapeutics and innovative bioprocessing applications, today announced that Maher Masoud has been named President and Chief Executive Officer of MaxCyte, succeeding Doug Doerfler, who will retire as President and Chief Executive Officer, effective January 1, 2024. Mr. Masoud, currently the Company’s EVP, Head of Global Business Development and Chief Counsel, will also serve as a director on MaxCyte’s Board of Directors. Mr. Doerfler will step down from the Board of Directors upon his retirement and will remain an advisor to the Company.

Mr. Doerfler founded MaxCyte in 1999 and served as CEO for 24 years, leading the Company from initial technology concept through to the commercialization of its flow electroporation technology. Mr. Doerfler’s team built MaxCyte into a leading cell-engineering company with a significant number of customers and partners, leveraging MaxCyte’s non-viral delivery platform in their pre-clinical and clinical work. During his tenure, Mr. Doerfler steered MaxCyte through numerous key events including initial public offerings on the UK AIM Exchange and U.S. NASDAQ Exchange, the development of the ExPERT instrument portfolio, and supporting the approval of CASGEVY™, the first non-viral cell therapy product approved by the FDA.

“Consistent with the Board’s succession planning process, the Board identified Maher Masoud as a leader with a deep understanding of our technology and the cell and gene therapy industry who can continue to build on MaxCyte’s accomplishments. Having worked closely with Maher over the past seven years, we are confident in his abilities to assume the role of President and Chief Executive Officer of MaxCyte," said Richard Douglas, chairman of the Board. "On behalf of the Board, I would also like to acknowledge Doug’s exceptional contributions to, and leadership of, MaxCyte over the past 24 years. Throughout Doug’s tenure, MaxCyte grew to become the partner of choice to leading cell and gene therapy drug developers."

"It has been a privilege being part of MaxCyte's exceptionally talented team over the past 24 years as we've worked together to develop our proprietary flow electroporation technology, building MaxCyte into the successful company it is today," said Mr. Doerfler. "Maher has been instrumental in key initiatives at MaxCyte, including building out our roster of Strategic Platform Licenses. He has also played a key role across the operating areas of the Company, including sales, marketing, and business development. I am confident in the Board’s choice and Maher’s ability to execute and drive MaxCyte’s continued success in the years to come."

Mr. Masoud brings more than 25 years of experience in the biopharmaceutical industry, including 17 years as an attorney and general counsel, to his new role at MaxCyte. Mr. Masoud has most recently served as EVP, Head of Global Business Development and Chief Counsel at MaxCyte. During his tenure, MaxCyte’s SPL partnership model grew to include 23 partners, as of December 2023. Mr. Masoud started his biopharmaceutical career as a research associate with Glen Research, a Maravai company, before joining Human Genome Sciences as Director and Corporate Counsel, overseeing legal activities for the company’s global clinical trials, until its acquisition by GlaxoSmithKline. Prior to joining MaxCyte, he oversaw the operations of six business subsidiaries at Wellstat, a life science holding company. During his tenure at Human Genome Sciences and Wellstat, Mr. Masoud supported the launch of three FDA approved therapies, Benlysta®, Vistogard® and Xuriden®. Mr. Masoud earned his Juris Doctor degree from Michigan State University College of Law after completing his Bachelor of Science degree in cell and molecular biology genetics from the University of Maryland.

"l am honored by the opportunity to lead MaxCyte. While working closely with Doug, the executive leadership team, and the Board over the past seven years, MaxCyte has grown to become the leading non-viral cell engineering company,” said Mr. Masoud. “I firmly believe in the broad and growing commercial opportunity for MaxCyte’s product line and the potential of our partners to bring meaningful product therapies to market. I look forward to leading our stellar team and continuing to build long-term shareholder value.”
