AZD4573 as Monotherapy or in Combinations With Anti-cancer Agents in Patients With r/r PTCL or r/r cHL

Module 1 will consist of two r/r PTCL cohorts and one cHL cohort; and each cohort includes 21 participants. A comprehensive initial review of all safety and PK/PD data will be conducted in approximately the first 6 participants of each cohort (safety run-in), with separate Safety Review Committees (SRCs) for each cohort executed independently. The safety assessment will be undertaken by the SRC. Each cohort will have a separate dose confirmation, assessed independently by the SRC, to assess safety and PK/PD data compared to the known profiles in the first time in human study (Study D8230C00001) lymphoma population. These SRC reviews will confirm whether the recommended phase II dose for lymphoma (IV infusion 12 mg once weekly, including intra-participant ramp-up) is safe and tolerable or if additional dose optimisation is indicated at a revised dose and/or schedule. All cohorts can be opened and delivered independently of each other.
