Primary Outcome Measures
NameTimeMethod
Number of Participants With Dose Limiting Toxicities (DLT)28 days

Number of participants with DLT in the first cycle (28 days) for the determination of the maximum tolerated dose (MTD). Important Limitations and Caveats are provided in the respective section.

Maximum Tolerated Dose (MTD) of Afatinib in Combination With Herceptin(R)28 days

The MTD was defined as the highest dose at which no more than 1 of 6 patients experienced DLT. It was determined using a standard 3 + 3 dose escalation cohort design. To confirm the MTD, the MTD cohort was to be expanded to 18 patients with no more than 3/18 patients experiencing a DLT. Please refer to CAVEATs and Limitations.

Secondary Outcome Measures
NameTimeMethod
Number of Patients With Objective Response (OR)Tumor assessment was performed at screening and every 2nd cycle until earliest time of progression, death or end of treatment.

Objective tumor response based on response evaluation criteria in solid tumors (RECIST) version 1.1. OR is defined as complete response (CR) or partial response (PR).

Progression Free Survival (PFS)Baseline until disease progression, death or data cut-off.

PFS is defined as time from randomisation to disease progression or death whichever occurs first. Assessed by central independent review according to the response evaluation criteria in solid tumors (RECIST 1.1). Median time results from unstratified Kaplan-Meier estimates.

Summary of Concentration of Herceptin in Plasma0.05 hours (h) before dosing and 0.5-1h, 2h, 3h, 4h, 5h, 6h, 8h after dosing

Pre-dose Concentrations of Herceptin in Plasma on Days 8, 15 and 29 (Cpre,8, Cpre,15 and Cpre,29) and Maximum Concentration of Herceptin in Plasma on Days 1, 15 and 29 (Cmax,1, Cmax,15 and Cmax,29).

Number of Patients With Best Overall ResponseTumor assessment was performed at screening and every 2nd cycle until earliest time of progression, death or end of treatment.

Best overall response based on response evaluation criteria in solid tumors (RECIST) version 1.1. Best overall response is defined as complete response (CR), partial response (PR), stable disease (SD), progressive disease (PD) or not evaluable.

Summary of Concentration of Afatinib in Plasma0.05 hours (h) before dosing and 0.5-1h, 2h, 3h, 4h, 5h, 6h, 8h after dosing

Pre-dose Concentrations of Afatinib in Plasma at Steady State on Days 8, 15 and 29 (Cpre,ss,8, Cpre,ss,15 and Cpre,ss,29) and Maximum Concentration of Afatinib in Plasma at Steady State (Cmax,ss).

Time From Dosing to the Maximum Concentration of Afatinib in Plasma at Steady State (Tmax,ss)0.05 hours (h) before dosing and 0.5-1h, 2h, 3h, 4h, 5h, 6h, 8h after dosing

tmax,ss represents the time from dosing to the maximum concentration of afatinib in plasma at steady state
