Treatment and study plan

Avelumab

Drug

Participants received avelumab intravenous infusions at a dose of 800 milligram (mg) on Day 1 and Day 8 of each 3-week cycle for the first 4 cycles. Thereafter, administered every 2 weeks in the Maintenance phase until disease progression or unacceptable toxicities.

Cetuximab

Drug

Participants received cetuximab intravenous infusions at a dose of 250 milligram per meter square (mg/m^2) body surface area on Day 1 and 500 mg/m^2 body surface area on Day 8 of first 4 cycles of concurrent chemotherapy. Thereafter, administered given at a dose of 500 mg/m^2 intravenous every 2 weeks in the Maintenance phase, until disease progression or unacceptable toxicities.

Gemcitabine

Drug

Participants received gemcitabine intravenous infusions at a dose of 1250 mg/m^2 body surface area on Day 1 and Day 8 in 3-week cycles up to a maximum of 4 cycles, until disease progression or unacceptable toxicities.

Cisplatin

Drug

Participants received cisplatin intravenous infusions at a dose of 75 mg/m^2 body surface area on Day 1 of 3-week cycles up to a maximum of 4 cycles, until disease progression or unacceptable toxicities.

carboplatin

Drug

In case of cisplatin toxicities, participants were switched to carboplatin at a dose of target area under the serum concentration-time curve of 5 (AUC 5) on Day 1 for the remainder of cycles.

Primary outcomes

  1. Percentage of Participants With Confirmed Best Objective Response (BOR) According to Response Evaluation Criteria In Solid Tumors (RECIST) Version 1.1 Assessed by Investigator

    Time frame: Time from the first dose of study drug until occurrence of PD, death due to any cause (assessed up to 612 days)

    Confirmed BOR was defined as the percentage of participants who achieved confirmed complete responses (CR) or partial response (PR), according to RECIST version 1.1 assessed by the Investigator.CR: Disappearance of all evidence of target and non-target lesions. PR: At least 30 percent (%) reduction from baseline in the sum of the longest diameter (SLD) of all lesions. Stable disease (SD)= Neither sufficient increase to qualify for progression of disease (PD) nor sufficient shrinkage to qualify for PR. PD: At least a 20 % increase in the SLD, taking as reference the smallest SLD recorded from baseline or the appearance of 1 or more new lesions. Confirmed CR=as at least two determinations of CR at least 4 weeks apart with no PD. Confirmed PR=as at least 2 determinations of PR or better (PR followed by PR or PR followed by CR), at least 4 weeks apart (not qualifying for a CR) with no PD in between. Percentage of Participants with confirmed BOR were reported.

Secondary outcomes

  1. Number of Participants With Treatment-Emergent Adverse Events (TEAEs), Treatment-Related Adverse Events (AEs), Treatment-Related Grade >=3 TEAEs and Immune-related Treatment Emergent AEs (irTEAEs)

    Time frame: Time from the first dose of study drug assessed up to (941 days)

    Adverse event (AE) was defined as any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease associated with the use of study drug, whether or not considered related to the study drug or worsening of pre-existing medical condition, whether or not related to study drug.Serious adverse event (SAE) was an AE that resulted in any of the following outcomes: death; life threatening; persistent/significant disability/incapacity; initial or prolonged inpatient hospitalization; congenital anomaly/birth defect or was otherwise considered medically important. TEAE is defined as AEs starting or worsening after the first intake of the study drug. TEAEs include both Serious and non-serious TEAEs. irAEs included AEs that matches a preferred term on the list of pre-selected MedDRA terms. AEs with relationship to study treatment are reported as Treatment-related AEs. Treatment related AEs with grade 3 or more is also reported.

  2. Progression-Free Survival (PFS) Time Per Response Evaluation Criteria in Solid Tumors (RECIST) 1.1

    Time frame: Time from the first dose of study drug until occurrence of PD, death due to any cause (assessed up to 737 days)

    Progression free survival (PFS) is defined as the time (in months) from first treatment day to the date of the first documentation of objective progression of disease (PD) according to RECIST version 1.1 assessed by Investigator, or death due to any cause, whichever occurs first. PD is defined as at least a 20 percent (%) increase in the SLD, taking as reference the smallest SLD recorded from baseline or the appearance of 1 or more new lesions.

  3. Duration of Response (DOR)

    Time frame: Time from the first dose of study drug until occurrence of PD, death due to any cause or last tumor assessment (assessed up to 612 days)

    DOR is defined for participants with confirmed complete response (CR) or partial response (PR), as the time from first documentation of confirmed response to the date of first documentation of progression of disease (PD) according to RECIST version 1.1 (assessed by Investigator) or death due to any cause or tumor assessment. Duration of objective response was assessed using Kaplan-Meier analysis. CR: Disappearance of all evidence of target and non-target lesions. PR: At least 30% reduction from baseline in the SLD of all lesions. PD: At least a 20 percent (%) increase in the SLD, taking as reference the smallest SLD recorded from baseline or the appearance of 1 or more new lesions.
