Number of patients with adverse events and with serious adverse events including abnormal clinical observations, abnormal ECG parameters, abnormal laboratory assessments and abnormal vital signs that changed from baseline

From time of Informed Consent to 28 + 7 days post last dose ( modules 1,2,3,5 and 6). 40+7 days post last dose for Module 4.
The number of subjects with dose-limiting toxicity (DLT), as defined in the protocol.
時間枠:From first dose of study treatment until the end of Cycle 1.

A DLT is defined as any toxicity that occurs from the first dose of study treatment (either AZD5305 or combination anti-cancer agent) up to and including the planned end of Cycle 1 (the DLT assessment period) that is assessed as unrelated to the disease or disease-related processes under investigation. DLTs occurring outside the DLT window (ie, late onset toxicities) may be defined as a DLT after consultation with the sponsor and investigators, based on the emerging safety profile.

From first dose of study treatment until the end of Cycle 1.
