Study Endpoints
Primary Endpoints
The number of patients with adverse events
From first dose of study drug up to 90 days post last dose and prior to start of subsequent anticancer therapy

Number of patients with adverse events by system organ class and preferred term

The number of patients with adverse events of special interest
From first dose of study drug up to 90 days post last dose and prior to start of subsequent anticancer therapy

Number of patients with adverse events of special interest by system organ class and preferred term

The number of patients with dose-limiting toxicity (DLT), as defined in the protocol.
From first dose of study drug until the end of Cycle 1

A DLT is a toxicity as defined in the protocol that occurs from the first dose of study drug 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.

The number of patients with serious adverse events
From first dose of study drug up to 90 days post last dose and prior to start of subsequent anticancer therapy

Number of patients with serious adverse events by system organ class and preferred term

Objective Response Rate (ORR)
From first dose of study drug to progressive disease or death in the absence of disease progression (approx. 2 years)

The percentage of patients with a confirmed investigator assessed complete or partial response according to response criteria in solid tumours (RECIST 1.1). Dose expansion only.

Secondary Endpoints
Objective Response Rate (ORR)
From first dose of study drug to progressive disease or death in the absence of disease progression (approx. 2 years)
Disease Control Rate (DCR)
From first dose of study drug to progressive disease or death in the absence of disease progression (approx. 2 years)
Duration of response (DoR)
From the first documented response to progressive disease or death in the absence of disease progression (approx. 2 years)
