“We are excited to reach this agreement with Johnson & Johnson for advancing scientific research to treat cancers with high unmet needs,” said Daniel J. O’Connor, Chief Executive Officer of Ambrx. “With our deep and unique knowledge of precision engineering of protein therapeutics enabled by our proprietary technology incorporating synthetic amino acids in living cells, Ambrx has developed nextgeneration novel drug candidates such as site-specifically conjugated highly stable antibody drug conjugates. Through this transaction, we will continue to advance our leading prostate cancer candidate and Ambrx’s promising pipeline, while delivering significant and certain cash value to our shareholders. This announcement is the culmination of two decades of scientific work, combined with the Ambrx team’s talent, hard work and innovation. I look forward to what Ambrx will achieve as part of Johnson & Johnson.”
