This is a study to evaluate the safety and potential anti-tumor activity of an investigational agent called ARV-806 in Adults with Advanced Cancer having a specific Kirsten rat sarcoma viral oncogene homolog (KRAS) mutation. This is an open-label study which means that participants and study staff will know that all participants will receive ARV-806. Researchers think that ARV-806 can work by breaking down a specific protein with a mutation that is present in some tumors, which might help prevent or slow tumors from growing. This will be the first time ARV-806 will be used in people. The investigational drug will be given through a vein. This is called intravenous (IV) infusion. This study will include 2 parts: In Part A (Phase 1), different small groups of participants will receive lower to higher doses of ARV-806. Adults with advanced cancers having a specific KRAS mutation will be included. In Part B (Phase 2), participants will be assigned to receive one of up to 2 dose levels decided by the information from Part A. Part B will include participants with advanced pancreatic ductal cancer having a specific KRAS mutation.
Phase 1 trials primarily test safety and dosing in a small number of participants (typically 20–100). Results do not yet speak to efficacy. FDA approval is typically many years away from this stage.
Phase 2 trials begin testing efficacy in a larger patient group (100–300). This is often where biotech binary events occur — positive Phase 2 data can significantly advance a company's pipeline narrative, while failures can be terminal for a program.
Enrollment is complete. The trial is in its follow-up or data collection phase — a readout may occur on or near the primary completion date.
Arvinas Inc (ARVN) is the sponsoring company for this trial. BiotechSign currently grades this company C (55/100) based on composite catalyst signals across its full pipeline. This trial is one data point in that overall catalyst picture.
