MaxCyte to Present Pre-Clinical CARMA Data at AACR Meeting

-    In vivo research demonstrates potential of novel, proprietary, CARMA product candidate for use in developing immunotherapies for the treatment of solid tumours

Maryland, USA - 2 March 2017: MaxCyte (LSE: MXCT), a US-based global company dedicated to accelerating the discovery, development, manufacturing and commercialization of next-generation, cell-based medicines, announced today it will present results of pre-clinical in vivo research demonstrating the potential of its novel, proprietary, CARMA platform for use in developing immunotherapies for the treatment of solid tumours at the American Association for Cancer Research (AACR) Annual Meeting in Washington, DC on 4 April 2017.

Using MaxCyte's unique, rapid-manufacture CARMA platform in immuno-oncology, MaxCyte and its collaborators at the Johns Hopkins Kimmel Cancer Center demonstrated that preclinical in vivo testing of CARMA-hMeso (i.e., mesothelin-specific mRNA CAR-transfected peripheral blood lymphocytes) containing mesothelin-expressing tumour cells resulted in killing of tumour cells and in increased overall survival; with multiple repeat weekly administration of CARMA-hMeso permitting prolonged control over tumour growth and increased overall survival compared to a single administration.

"These data represent a major pre-clinical milestone for MaxCyte's CARMA programme as the results demonstrate the ability of a CARMA immunotherapy to effectively inhibit tumour growth and prolong survival in an animal model of disease," said Doug Doerfler, President & Chief Executive Officer. "The data provide a strong scientific foundation for translational development of our rapid-manufacture CARMA platform to quickly develop tumour-targeted immunotherapies using peripheral blood lymphocytes. We can control 'on-target, off-tumour' toxicities, while reducing manufacturing cost and complexity for therapies targeting both solid cancers and hematological malignancies, beyond B-cell tumours."

 Data will be shared via a poster (Permanent Abstract Number: 3748) at the AACR Annual Meeting 2017 as follows:

Session: "Innate Effectors in Immunity to Cancer"

Date: Tuesday, 4 April 2017 

Time: 8:00 a.m. - 12:00 p.m. ET
