Medical Director, Immuno-Oncology Clinical Development Lead

Medical Director For Immunotherapy Clinical Trials

As Client expands its clinical portfolio, we are preparing to initiate clinical trials for our lead novel immunotherapy for solid tumors. We are seeking a Medical Director to lead the program's clinical development strategy and execute a FIH study. You will have the opportunity to shape clinical strategy and execution from the ground up and serve as a key clinical voice across internal and external stakeholders. This role reports directly to the Executive Vice President of R&D and works closely with other functional teams. You will be expected to serve as a strategic clinical, medical, and operational leader, where you will help to define and oversee all clinical aspects of the program including protocol design, tumor indication prioritization, dose selection and dose escalation, drug administration, patient eligibility/enrollment, medical monitoring, and regulatory engagement. This role is ideally suited for someone with direct hands-on leadership experience in early-phase clinical trials within pharmaceutical or biotechnology companies. The ideal candidate will have deep clinical insights on immunotherapies and must be able to thrive in dynamic, early-stage biotech settings where resourcefulness, scientific rigor, and a proactive approach are critical to driving novel therapies forward.
