Text in the graphics appear illegible. Please update these graphics accordingly. In addition, we note the graphics contain technical jargon, including "RP2D" and "Traditional 3+3," and elsewhere in your registration statement we note technical terms, such as "SUV scores." Define these terms in a way that a lay person can understand. In addition, please provide narrative disclosure to clarify your clinical development plant for each of your product candidates depicted in your updated graphics. Deep, Broad, Differentiated Preclinical Discovery Pipeline, page 172 4. We note your updated disclosure, including your updated pipeline chart on page 173. Please revise your chart to indicate the material stages you will need to complete before marketing your products. For instance, please add Phase I, II and III to your chart. In addition, your pipeline table includes three separate pre-clinical phases, which gives the impression that your product candidates are farther along in the clinical process. Please revise the table to eliminate the separate column for lead identification, as this stage is not sufficiently distinct. Also revise to delete the rows for any preclinical product candidate that is not currently material. AI-Powered Antibody Discovery, page 176 5. We note your updated disclosure and your claim that your "DPL platform is designed to substantially improve the probability of success for the overall R&D process." Given the early stage of product candidates and your statement elsewhere that "the results of [y]our current and previous preclinical studies or clinical trials may not be predictive of future results," please remove this claim or otherwise advise.
