• Locally advanced (stage IIIb) or metastatic (stage IV) NSCLC not considered eligible for curative therapy.

• Documented disease progression or relapse (based on investigator's assessment) during or after completion of at least 2 cycles of platinum-based chemotherapy as first line treatment of Stage IIIB/IV SCC of the lung. This includes patients relapsing within 6 months of completing (neo)adjuvant/curative-intent chemotherapy or definitive chemoradiotherapy. Patients should be eligible to receive 2nd line therapy in the opinion of the investigator.

• At least one target lesion (outside the brain) that can be accurately measured per Response Evaluation Criteria in Solid Tumours (RECIST) version 1.1. In patients who only have one target lesion and a biopsy of the lesion is required; the baseline imaging must be performed at least two weeks after the biopsy.

• Availability and willingness to provide a fresh tumour tissue sample obtained after relapse or progression on or after prior therapy. In case a fresh biopsy cannot be obtained (e.g. inaccessible lesions or patient safety concern), an archived specimen may be submitted.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Objective Response Rate (ORR)	Objective response rate is defined as percentage of participants with the best overall response of complete response (CR, disappearance of all target lesions) or confirmed partial response (PR, at least a 30% decrease in sum of diameter (SoD, longest diameter (LD) measured for all lesions except lymph nodes, where shortest diameter (ShD) was used) of target lesions, reference is baseline SoD). Tumour response was assessed based on local radiological image (Computerised tomography (CT) or Magnetic resonance imaging (MRI)) evaluation by the investigators according to Response Evaluation Criteria In Solid Tumours (RECIST) version 1.1.	Tumour assessment performed at screening (-28 days), week 9 (day 56-63) after study treatment (afatinib or pembrolizumab) start and every 9th week thereafter, up to 556 days.
Secondary	Recommended Phase II Dose (RP2D)	Recommended Phase II Dose (RP2D) was to be calculated through a Bayesian logistic regression model (BLRM) with overdose control that was to be fitted to binary toxicity outcomes. After 12 patients had completed at least one cycle (one cycle equals 21 days and consists of one time infusion of pembrolizumab at Day 1 + daily intake of afatinib) of treatment, the prior distributions were to be updated through Gibbs sampling procedures with the accumulated dose limiting toxicity (DLT) data from the first treatment cycle. The estimate of parameters was to be updated as data were accumulated using the BLRM. At the end of the dose confirmation, the toxicity probability at each dose level was to be calculated to determine an estimate of the RP2D. Posterior probabilities for the rate of DLT were to be summarised from BLRM. Confirmation of the RP2D by the Safety Monitoring Committee (SMC) was to be based on these probabilities as well as on the review of other safety and laboratory data.	21 days (1 treatment cycle) from study treatment (afatinib and pembrolizumab) administration.
Secondary	Disease Control Rate (DCR)	Disease control rate was calculated as percentage of participants with CR, PR, or stable disease (SD, neither sufficient shrinkage to qualify for PR, taking as reference the baseline sum of diameters (SoD), nor sufficient increase to qualify for progressive disease (PD, at least a 20% increase in the SoD of target lesions, taking as reference the smallest SoD recorded on study (including baseline), together with an absolute increase in the SoD of at least 5 millimeter (mm ) or the appearance of one or more new lesions). Tumour response was assessed based on local radiological image (Computerised tomography (CT) or Magnetic resonance imaging (MRI)) evaluation by the investigators according to Response Evaluation Criteria In Solid Tumours (RECIST) version 1.1.	Tumour assessment performed at screening (-28 days), week 9 (day 56-63) after study treatment (afatinib or pembrolizumab) start and every 9th week thereafter, up to 556 days.
Secondary	Duration of Objective Response (DOR)	For participants who showed objective response, duration of objective response (DoR), was defined as the time from first documented complete response (CR) or partial response (PR) until the earliest of disease progression (PD) or death. Tumour response was assessed based on local radiological image (CT or MRI) evaluation by the investigators according to RECIST version 1.1. The number of participants with objective response who experienced the event "disease progression or death (whichever came first)" is reported instead of a metric summarizing the time-to-event data with unit of time, as the number analyzed was too small to perform a Kaplan-Meier-analysis.	Tumour assessment performed at screening (-28 days), week 9 (day 56-63) after study treatment (afatinib or pembrolizumab) start and every 9th week thereafter, up to 436 days.
Secondary	Progression-free Survival (PFS)	Progression-free survival was defined as the time (weeks) from the date of the first afatinib or pembrolizumab administration to the date of disease progression (at least a 20% increase in the sum of diameter (SoD, longest diameter (LD) measured for all lesions except lymph nodes, where shortest diameter (ShD) was used) of target lesions, taking as reference the smallest SoD recorded on study (including baseline), together with an absolute increase in the SoD of at least 5 mm or the appearance of one or more new lesions) or death (if the patient died without progression). The date of progression for the primary analyses was determined based on investigator assessment. Tumour response was assessed based on local radiological image (Computerised tomography (CT) or Magnetic resonance imaging (MRI)) evaluation by the investigators according to RECIST version 1.1. Median and 95% Confidence Interval were calculated using Kaplan-Meier estimates.	Tumour assessment performed at screening (-28 days), week 9 (day 56-63) after study treatment (afatinib or pembrolizumab) start and every 9th week thereafter, up to 556 days.
Secondary	Overall Survival (OS)	Overall survival is defined as the time from the date of treatment start to the date of death from any cause. Participants without event were censored. Median and 95% Confidence Interval were calculated using Kaplan-Meier estimates.	From Day 1 of study treatment (afatinib or pembrolizumab) administration up to a total of 574 days.
Secondary	Tumour Shrinkage	Tumour shrinkage (in millimeters) is defined as the difference between the minimum post-baseline sum of diameters of target lesions (SoD, longest for non-nodal lesions, short axis for nodal lesions) and the baseline sum of diameters of the same set of target lesions. Tumour shrinkage is reported as percentage change from baseline and represents the maximum decrease or the minimum increase from baseline in SoD in percentage of the baseline SoD. Negative values indicate a reduction in the SoD; positive values indicate an increase in the SoD. Tumour response was assessed based on local radiological image (CT or MRI) evaluation by the investigators according to RECIST 1.1.	Tumour assessment performed at screening (-28 days), week 9 (day 56-63) after study treatment (afatinib or pembrolizumab) start and every 9th week thereafter, up to 556 days.
