Study Endpoints

Primary Endpoints

Parts A and B: Number of participants with adverse events (AEs) and serious adverse events (SAEs)
From Screening (Day -28) to follow-up (up to 3.5 years)

To assess the safety and tolerability of AZD4956 monotherapy and in combination with anti-cancer agent(s).

Part B: Progression free survival (PFS)
Up to 3.5 years

PFS is defined as the time from the start of treatment until the date of objective disease progression or death (by any cause in the absence of progression), regardless of whether the participants withdraw from study treatment or receive another anti-cancer therapy prior to progression.

Part A - Number of participants with dose-limiting toxicities (DLTs)
Up to 28 days

To assess the safety and tolerability of AZD4956 monotherapy and in combination with anti-cancer agent(s).

Secondary Endpoints

Objective response (OR)
Up to 3.5 years
Duration of response (DoR)
Up to 3.5 years
Best Overall Response (BOR)
Up to 3.5 years
