  • Deep understanding of in vivo Pharmacology (PK, PD and efficacy) concepts for oncology drug discovery including I-O biology and related drug mechanisms.
  • Extensive experience using in vivo tumor models for drug discovery with a proven track record in hands-on establishment, validation, and implementation of animal models for testing cancer therapies, including xenograft, syngeneic, genetically engineered mouse, orthotopic, PDX and humanized models to study biologic mechanisms.
  • Proven track record of writing regulatory and IND filing documents in the pre-clinical Pharmacology section.
  • Proven track record of good experimental design, in-depth data analysis and interpretations based on strong scientific rationale.
  • Expertise in cell culture with aseptic technique and basic in vivo techniques (handling different routs of administration, blood collection, etc.) is a must.
  • Strong scientific expertise with a good track record of publications.
  • Experience working with CROs to coordinate and execute studies in a timely manner.
  • In vivo skills including, but not limited to, animal handling, dosing with different routes (po, iv, sc, ip, im, etc.), blood collection, tissue collection/perfusion, necropsy, tumor measurement, clinical observation, and rodent survival surgeries.
  • Solid biological and mechanistic understanding of biologics in oncology and immune-oncology including specific and specialized readouts and protocols for in vivo studies.
