Part 2 dose expansion will evaluate ZX-101A activity in up to three disease-specific cohorts. Inclusion of combination therapy is planned after obtaining the initial clinical assessment of ZX-101A on its safety, tolerability, pharmacokinetics, and pharmacodynamics in patients.
Its absorption, distribution, metabolism, and excretion (ADME) and safety profile, through a series of preclinical in vitro and in vivo studies, supported the ZX-101A clinical development. These results suggested ZX-101A as a potential immunotherapeutic agent to appropriate solid tumor types.
