AlivaMab Discovery Services Expands Drug Discovery Platform with the Launch of New Antibody Engineering Department

Jonah Rainey, Ph.D., joins ADS to bring new breadth and depth of capabilities and expertise in discovering therapeutic antibody modalities

SAN DIEGO, Calif. – May 12, 2021 – AlivaMab Discovery Services, LLC ("ADS"), a leader in the discovery of superior antibody therapeutics, today announced the establishment of its new Antibody Engineering Department, led by Jonah Rainey, Ph.D.  Jonah joins ADS as Vice President of Antibody Engineering and brings 15 years' experience in antibody engineering, discovery, and development from Macrogenics Inc., MedImmune, LLC/AstraZeneca PLC, Gritstone bio, Inc., and, most recently, Immetas Therapeutics, Inc. Jonah's breadth of experience in antibody engineering includes bispecific antibodies, several of which have entered clinical trials, antibody drug conjugates, Fc modification, in vitro display for antibody discovery and optimization, and structural modeling.

“A growing number of leading pharmas and biotechs recognize that the already-existing platform process at ADS has created exceptional value for their antibody drug discovery efforts. I am excited to lead the effort to build new capabilities at ADS to expand the scope and value that we bring to our clients' drug discovery and development projects. The contribution of the new Antibody Engineering Department will further ensure that ADS delivers the best antibody drug candidates,” said Jonah Rainey, Vice President of Antibody Engineering, of AlivaMab Discovery Services.

“Today we expand significantly the ADS discovery platform by adding a new pillar of antibody engineering to our existing pillars of Ablexis' AlivaMab® Mouse, the leading transgenic animal technology for antibody drug discovery, a suite of AMMPD immunization technologies to address even the most challenging targets, broad sampling of the immune repertoire through function-first high-throughput deep screening, and developability assessment,” said Justin Mika, Chief Executive Officer at AlivaMab Discovery Services. “Jonah‘s talents and expertise strengthen and compliment the combined decades of experience in discovery and development of the ADS team. Through this combination of team, technology, and partnership, we support our clients in bringing better medicines to patients faster.”
