A Study of AP601 in Patients With Locally Unresectable Advanced or Metastatic Solid Tumors

AP601 is a fully human bispecific antibody designed for the treatment of CD73-expressing solid tumours. Participants will receive a single infusion of AP601 once every 2 weeks (14 days) (Q2W) for up to 12 months. All doses of AP601 will be admistered intraveneously. The infusion time for all doses of AP601 in each patient will be approximately 60 to 120 minutes.
