Primary Outcome Measures
NameTimeMethod
Number of participants with Treatment-emergent Adverse Events (TEAEs)up to 2 years

Define as adverse events reported for the first time or worsening of a pre-existing event after first dose of study drug monotherapy and in combination with cetuximab.

Number of participants with Dose Limiting Toxicities (DLTs)up to 21 days

DLTs will be defined as the occurrence of any of the toxicities as described in the protocol.

Secondary Outcome Measures
NameTimeMethod
Duration of response (DoR)up to 2 years

Duration of response (DoR) is defined as the time between first evidence of objective response and disease progression (as measured by RECIST 1.1) or death, whichever occurs earlier, in subjects who achieve CR or PR.

Area under the plasma concentration-time curve (AUC) of QTX3046up to 2 years

Plasma concentration data for QTX3046 will be used to evaluate the area under the plasma concentration-time curve (AUC) of QTX3046

Peak plasma concentration of QTX3046 (Cmax)up to 2 years

Plasma concentration data for QTX3046 will be used to evaluate peak plasma concentration (Cmax) of QTX3046

Objective response rate (ORR)up to 2 years

The ORR is defined as the proportion of patients with a best overall response of complete response (CR) or partial response (PR) based on RECIST 1.1.
