a 
Screening: the screening visit should be performed within 28 days of the first dose of  afatinib. Safety lab at the 
screening assessment can serve as the Day 1 pre-treatment assessment of Course 1 if performed within 72 hours 
before the first treatment and does not need to be repeated  
b
Treatment courses: all courses are 4 weeks in duration (28 days). During the treatment period, clinical assessments 
and safety laboratory tests must be performed prior to study drug administration on the visit day. All subsequent 
visit dates should be calculated based on Course 1 Visit 1 date. One or more visits can be skipped in case of 
treatment interruption. Patients may continue on treatment until the criteria for stopping medication are met (see 
Section 3.3.4). 
c
EOT: if the decision to permanently discontinue afatinib treatment is taken during a scheduled visit, the End Of 
Treatment (EOT) visit should be performed instead of the scheduled visit ( or within 7 calendar days after last drug 
administration)
d
FU: all patients should have a follow-up (FU) visit 28+7 days after the permanent discontinuation of afatinib
e
Written informed consent must be obtained before any protocol specific screening assessment is performed
f
A 12-lead resting digital electrocardiogram (ECG) will be performed at Screening and reviewed by the 
investigator. Refer to Section 5.2.4 for details
g
Physical exam: includes a thorough cardiopulmonary, abdominal and regional lymph node exam and an 
assessment of the mental and neurological status. No need to repeat the physical exam on C1V1D1 if within three 
calendar days of the screening physical exam and the patient is deemed stable by the investigator
h
Vital signs: includes respiratory rate, pulse, temperature and blood pressure
i
Safety lab: CBC: include white blood cell count, neutrophil and bands, differential, hemoglobin, hematocrit and 
platelet count. Serum chemistries: include sodium, potassium, chloride, bicarbonate, BUN, creatinine, glucose, 
AST, ALT, GGT, total bilirubin, alkaline phosphatase, calcium, magnesium. See Section 5.2.3
j
Additional laboratory assessments should be performed if clinically indicated 
k
Urine analysis: include pH, protein, glucose, ketones, blood, leucocytes, nitrite, bilirubin, urobilinogen, and 
specific gravity.  In case of pathological finding, further evaluation should be performed and results documented in 
the source document  
 
 
 
 
 
 
 
 
 
 
 
 
 
 
m
Interactive Response Technologies (IRT): patient’s screening, all drug dispensation visits and EOT will be 
collected in the IRT system 
n
Adverse event: from 28 days after last trial drug administration new AEs will only be collected, documented and 
reported if they are considered related to trial drug 
o
Concomitant therapy: during FU concomitant therapy only needs to be recorded if  indicated for the treatment of 
an AE

INTRODUCTION
1.1
MEDICAL BACKGROUND
Non-Small Cell Lung Cancer (NSCLC) is the leading cause of cancer-related deaths in many 
countries, including the US. The prognosis for advanced stage disease has improved modestly 
in the past 20 years. With an overall 5-year survival rate of only 15% the treatment of this 
disease clearly remains a major clinical challenge (R05-0867).
While systemic chemotherapy has demonstrated modest activity in advanced NSCLC, novel 
targeted therapies based on specific molecular and biological characteristics of lung cancer 
have emerged as a new treatment paradigm. Among the molecules most extensively studied 
are the Epidermal Growth Factor Receptors (EGFR) or the Subclass I of the superfamily of 
transmembrane tyrosine kinase receptors (R06-1301, R06-1302).
Aberrant activation of EGFR frequently observed in a variety of malignant tumors can be 
induced by different molecular mechanisms including receptor overexpression, mutation, 
ligand-dependent receptor dimerization, and ligand-independent activation. Overexpression 
of EGFR has been detected in 40% to 80% of NSCLC patients (R06-1301, R06-1393, R06-
1394). However, recent clinical experiences with specific EGFR-Tyrosine Kinase Inhibitors 
(TKI) have demonstrated tumor regression in only 10% to 15% of unselected NSCLC 
patients (R05-0867, R06-1301, R06-1306). The treatment with EGFR TKIs is associated with
higher Response Rate (RR) in patients with tumors which harbor EGFR mutations.  In a 
recent meta-analysis based on 13 randomized trials, the response rate was 70% vs. 33.2% in 
first-line trials. In three second-line trials, response rates were 47.4% vs. 28.5%, with a 
benefit similar to first-line trials (Relative Risk, 1.79; p = .04) (R12-4000).  Somatic 
mutations between exons 18 through 21 of the EGFR gene was found to occur in 
approximately 10% of NSCLC patients from the US, Europe or Australia compared to up to 
30% in patients from Japan and Taiwan (R06-1262, R06-1306, R06-1393). The most 
common EGFR mutations are a short, in-frame deletion in exon 19 (E19del [LREA deletion] 
found in approximately 46% of patients) and a point mutation (CTG to CGG) that results in a 
substitution of leucine by arginine at codon 858 of exon 21 ([L858R] found in 37.5% of 
patients) (R14-2119).
Two large multinational randomized Phase III studies of afatinib in the first line treatment of 
mutation positive stage IV NSCLC patients have been performed: the LUX-Lung 3 (1200.32) 
and LUX-Lung 6 (1200.34) studies. 
LUX-Lung 3 compared first line afatinib to up to six cycles of cisplatin /pemetrexed (N=345 
with 2:1 randomization). Adult patients with performance status (PS) 0-1 were included in 
the trial without age limitation. Seventy-two percent (72%) of all trial patients were Asian 
with the remainder classified as non-Asian. In this trial patients treated with afatinib 
demonstrated significant and clinically meaningful improvements in progression free survival 
(PFS, median PFS afatinib vs. cisplatin/pemetrexed 11.1 vs. 6.9 months, hazard ratio 0.58; 
95% CI, 0.43 to 0.78; P=.001) and Objective Response Rate (ORR, afatinib vs cisplatin 
/pemetrexed 56% vs. 23%; P= .001).  This was accompanied by significant delays in time to 
deterioration of the cancer-related symptoms of cough (afatinib /cisplatin pemetrexed, Hazard

0.93; P =.01). A pre-planned analysis of PFS in patients (n=308) with exon del 19 or L858R 
mutation was 13.6 months for afatinib and 6.9 months for chemotherapy (HR 0.47; 95% CI: 
0.34 to 0.65; P=0.001). Higher response rates were observed in afatinib groups compared 
with chemotherapy 69% and 44%, respectively (P13-07382 ).
LUX-Lung 6 compared first line afatinib to up to six cycles of cisplatin/gemcitabine (N=364 
with 2:1 randomization afatinib: cisplatin/gemcitabine). All patients were Asian. As in LUX-
Lung 3, patients with performance status 0-1 were included in the trial without age limitation. 
Patients treated with afatinib demonstrated significant improvements in progression free 
survival (median PFS afatinib vs. cisplatin/gemcitabine 11.0 months vs. 5.6 months, hazard 
ratio 0.28; 95% CI 0.20 to 0.39; P<0.0001) and ORR (afatinib vs. cisplatin/gemcitabine 
66.9% vs. 23.0 %, P <0 .0001).  This was accompanied by significant delays in time to 
deterioration of the cancer-related symptoms of cough (afatinib vs. cisplatin/gemcitabine HR
0.45, 95% CI, 0.30 to 0.68; P = .0001) and dyspnea (HR 0.54; 95% CI, 0.40 to 0.73; P< 
0.0001) [P14-00758]
In a separate single arm study (LUX-Lung 2) [P12-03681] in lung adenocarcinoma patients 
(stage IIIb with pleural effusion or stage IV) with EGFR mutations, 129 patients were treated 
in first-line or second-line with afatinib, 99 with a starting dose of 50 mg and 30 with a 
starting dose of 40 mg. 79 (61%) of 129 patients had an objective response (two complete 
responses, 77 partial responses). 70 (66%) of the 106 patients with the two most common 
activating EGFR mutations (deletion 19 or L858R) had an objective response, as did nine 
(39%) of 23 patients with less common mutations.
For patients previously treated with a reversible EGFR TKI and clinically enriched for EGFR 
mutations, treatment with afatinib plus best supportive care resulted in a significant 
improvement in median PFS over patients treated with a placebo plus best supportive care 
(LUX-Lung 1/1200.23) [U10-3048-01].This improvement in PFS was accompanied by 
significant and meaningful improvements in cough, dyspnoea, and pain, compared to the 
placebo group. Treatment with afatinib was also found to significantly delay the time to 
deterioration for Global Health Status/Quality of Life (QoL). 
A subsequent and larger study (LUX-Lung 5/1200.42) enrolling a similar population of 
patients resulted in a very similar median PFS as in LUX-Lung 1. In these studies, the PFS 
benefit of afatinib was consistent across all pre-planned subgroups with at least 50 patients, 
including gender, age, race, baseline Eastern Cooperative Oncology Group (ECOG) 
performance status, type of prior EGFR TKI, baseline tumor size, and lines of prior 
chemotherapy. In both of these studies (LUX-Lung 1 and 5) treatment with afatinib had the 
greatest PFS benefit for those patients who belonged to a subgroup highly clinically enriched 
for EGFR mutations or who were positive for EGFR mutations by testing of tumor tissue.

in tumour growth inhibition and regression of established subcutaneous tumours derived from 
four human cell-lines known to co-express ErbB receptors. 
For the latest information on the drug profile of afatinib, please refer to the current afatinib 
Investigator Brochure (IB) (c01802941-09).  All references in this protocol concerning 
afatinib refer to the free base compound afatinib which is used as the oral formulation.
Afatinib is moderately fast absorbed after oral administration. Maximum plasma 
concentrations of afatinib were achieved mainly at 2 to 5 hours after oral drug administration. 
Afatinib maximum plasma concentrations and area under the curve increased slightly over-
proportional with increasing doses in the therapeutic range of 20-50mg. Moderate to high 
inter- and intra-individual differences in plasma concentration were seen. Afatinib is highly 
distributed out of the blood and has a moderate to high clearance. The overall gMean terminal 
half-life at steady state was 37.2 hours in cancer patients. Steady state was reached no later 
than 8 days after the first administration. The major route of elimination of afatinib was via 
faeces. After food intake, a decreased systemic exposure was observed compared to 
administration under fasted conditions. Therefore, afatinib should be taken without food (i.e. 
food should not be consumed for at least 2 hours before and at least 1 hour after taking 
afatinib). The PK characteristics in Caucasian cancer patients were comparable to those 
observed in Japanese cancer patients. 
Afatinib is bound covalently to proteins to a variable extent and covalent protein adducts 
were the major circulating metabolites in the plasma. Afatinib did not show relevant 
inhibition or induction of cytochrome P450 isoenzymes, and it appears unlikely that drug-
drug interactions based on this mechanism will occur. 
Afatinib is a substrate of the P-gp transporter. Concomitant administration of the potent P-gp
inhibitor ritonavir did not relevantly change the exposure to 40 mg afatinib when taken
simultaneously with or 6 h after afatinib but increased the bioavailability of afatinib (single
dose of 20 mg) by 48% and 39% for AUC0-∞ and Cmax when given 1 h before afatinib,
respectively. Pretreatment with the potent P-gp inducer rifampicin decreased the plasma
exposure of 40 mg afatinib by 34 % afatinib (AUC0-∞) and 22 % (Cmax), respectively.
Caution should be exercised when combining afatinib with potent P-gp modulators.
In pre-clinical studies afatinib is not an irritant to intact skin but an ocular irritant.

Two phase I open label dose-escalation studies determined the Maximum Tolerated Dose 
(MTD) with continuous dosing of afatinib in patients with advanced solid tumours at 40mg 
and 50mg daily, respectively (U07-3128-02, U08-1023-02). Adverse events (AE) observed 
with afatinib are consistent with those reported for other EGFR and dual EGFR/HER2 
inhibitors. The most frequent investigator defined drug-related AEs were associated with 
gastrointestinal disorders (including diarrhoea, and stomatitis), skin and subcutaneous tissue 
disorders (rash, dry skin, pruritus, acneiform rash, acne), nail effects, epistaxis, fatigue, and 
decreased appetite. Early and proactive management of diarrhoea, mucositis/stomatitis and 
skin rash together with treatment interruptions and dose reductions is recommended in line 
with recent guidelines in the management of common toxicities of EGFR and EGFR/HER2 
TKIs and monoclonal antibodies (R07-4077, P07-11507, R07-4078).

RATIONALE, OBJECTIVES, AND BENEFIT - RISK 
ASSESSMENT
2.1
RATIONALE FOR PERFORMING THE TRIAL
The US registration of the EGFR TKIs afatinib and erlotinib has changed the clinical 
management of patients with advanced NSCLC (R06-1394, R06-1307, R07-1049, R07-
1134). A significant clinical benefit may be achieved by a treatment that controls NSCLC 
progression with acceptable levels of side effects through a defined and specific targeted 
molecular mechanism.
Elderly patients (variously defined in the literature as ≥ 65 years of age or >70 years of age)
tend to be underrepresented in clinical trials (R14-1781, R14-1839, R14-1840). For this trial 
we will define elderly patients as those patients who are 70 years of age or older. 
Half of all NSCLC patients are 70 years of age or older at the time of initial diagnosis (R14-
1781).
There are several retrospective subset analyses from large clinical trials of the safety and 
efficacy of EGFR TKIs in elderly patients (age > 70). These trials were conducted regardless 
of mutational status and allowed multiple prior lines of therapy (R09-2250, R14-1350). One 
such study in Canadian patients demonstrated significant improvement in progression free 
survival in both elderly and younger populations compared to placebo (R09-2250). Elderly 
patients however, had significantly more overall and severe toxicity (grade 3/4 35% vs. 
18.5%; p< .001).  The elderly were also more likely to have > grade 3 rash, fatigue, 
stomatitis, or dehydration.  
A subset analysis of a Japanese population based observational study in  patients ≥75 years of 
age treated with the same EGFR TKI as in the Canadian study was performed. Patients 
received treatment without regard to mutational status and had multiple prior lines of therapy.
In this study there was a statistical difference between the disease control rate in the elderly
and non- elderly (58.2 % vs. 42.5 % P= 0.0228). There was no statistical difference in the 
time to treatment failure or in overall survival between the two groups. There was also no 
significant difference in the occurrence of grade > 3 toxicities between the groups. [R15-
0770]  
Afatinib is approved in the United States for the first line treatment of patients with Exon 19 
Deletions or Exon 21(L858R) substitution mutations based on the results of the LUX-Lung 3 
clinical trial. In that first line trial, encompassing 345 patients with varying EGFR mutations, 
the mean age was 60.3 years; 230 patients were randomized to Afatinib, from which 48 
patients were 70 years of age.  Of these patients, 41 had exon 19 deletions or L858R 
mutations.
This trial is proposed to obtain additional information about the tolerability of treatment with 
first line afatinib in the US elderly population by evaluating the proportion of patients with 
AEs leading to dose reduction of afatinib.  It is felt that the use of the 30 mg dose of 
afatinib in this vulnerable patient population (patients with ECOG PS of 2 or 3) reflects 
actual clinical practice.

2.2
TRIAL OBJECTIVES
The objective of this study is to describe the occurrence of AEs leading to dose reduction 
following afatinib treatment in NSCLC patients with common EGFR mutations (Deletion 19
and/or L858R) who are 70 years of age or older. 
See Section 5 for a detailed description of the study endpoints.
2.3
BENEFIT - RISK ASSESSMENT
Despite recent advances, NSCLC still has a dismal prognosis with an overall 5 year survival 
rate of 15%.   Afatinib is approved in the United States for the first line treatment of patients 
with Exon 19 Deletions or Exon 21(L858R) substitution mutations. In the LUX-Lung 3 trial, 
afatinib showed a statistically significant and clinically meaningful improvement in PFS, 
response rate and lung cancer symptoms compared to chemotherapy in NSCLC patients with 
common EGFR mutation (P13-07382). Across all afatinib clinical trials, diarrhoea, including 
severe diarrhoea, has been reported during treatment. Diarrhoea may result in dehydration 
with or without renal impairment, which in rare cases has resulted in fatal outcomes. Diarrhea 
usually occurred within the first 2 weeks of treatment. Grade 3 diarrhea is reported in about 
15% of patients and most frequently occurred within the first 6 weeks of treatment. 
The dermatological AEs in afatinib trials are captured as group terms including rash, acne, 
paronychia, pruritus, dry skin, eczema, and folliculitis. Across all trials rash/acne occurred at 
a high frequency and half of the cases begin within 4 weeks of exposure to afatinib. Grade 3 
rash was observed in about 17-18% of patients and those at higher risk for Grade 3 rash/acne 
appear to be the patients of low body weight/body surface area and patients with low baseline 
renal function. 
Interstitial lung disease (ILD) is a rare and serious (potentially fatal) AE reported with other
EGFR TKIs. The frequency of ILD-like AEs in all afatinib treated patients was low 
(approximately 1%) and similar to that observed with other EGFR TKIs. In this study, 
patients with known pre-existing ILD will be excluded. Afatinib treatment will be interrupted 
if patients experience acute onset and/or unexplained worsening of pulmonary symptoms 
(including dyspnea, cough, and fever). If interstitial lung disease is diagnosed, study drug 
must be permanently discontinued and appropriate treatment should be instituted as 
necessary.
Although rare, a potential for drug-induced liver injury (DILI) due to afatinib is under 
constant surveillance by sponsors and regulators. Therefore, this study requires timely 
detection, evaluation, and follow-up of laboratory alterations of selected liver laboratory 
parameters to ensure patient safety.
Keratitis was identified using the MedDRA SMQ (Medical Dictionary for Drug Regulatory 
Activities Standardised MedDRA Queries) (narrow) for corneal disorders and Boehringer 
Ingelheim’s internal database was searched. In all afatinib-treated patients as of 15 January

2013, 32 patients (0.7%) were identified using the SMQ search with the most common 
preferred term being keratitis (19 patients [0.4%]).
In regard to treatment of older patients, in the LUX-Lung 3 study, the predominant adverse 
events noted in patients aged 70 and over (N= 48) receiving afatinib treatment were diarrhoea
95.8% (10.4% > grade 3), rash/acne 85.4% (12.5% > grade 3), stomatitis 66.7% (6.3% > 
grade 3) and nail effects 56.3% (16.7% > grade 3). These adverse events were treated 
symptomatically, and with treatment interruption and dose reductions. For patients aged 70 
and over, therapy was discontinued because of treatment related AEs in 14.6% of the patients 
receiving afatinib. Of the most common AEs associated with afatinib, only diarrhoea (4.2%) 
and paronychia (2.1%) were cause for treatment discontinuation. There were no cases of 
interstitial lung disease-like events potentially related to afatinib in patients 70 years of age or 
older. Two deaths in this age group were considered to be related to afatinib treatment (one 
respiratory decompensation and one sepsis). In the first line Lux Lung 6 trial encompassing
364 patients with varying EGFR mutations, one hundred percent of patients were Asian. The 
mean age was 56 years, 25 (6.9 %) afatinib patients were 70 years of age or older and had 
exon 19 deletions or L858R mutations. The tolerability of afatinib in this study was 
consistent with what was reported in the LUX-Lung 3 trial. .
In this study, the guideline for management of expected side effects of afatinib will be 
followed (refer to Section 4.4). Regular and frequent monitoring of the safety as well as the 
clinical benefit throughout the trial will be implemented, including scheduled clinical visits 
when the emergence of afatinib related AEs are expected.  Hence, early management and 
education will take place to mitigate worsening of symptoms. In addition, periodic tumor 
assessment will be performed by the investigator; patients lacking clinical benefit will be 
removed from afatinib treatment. 
In summary, there is a medical need for improving treatment of elderly patients with EGFR 
driver mutations.

3.      DESCRIPTION OF DESIGN AND TRIAL POPULATION
3.1
OVERALL TRIAL DESIGN AND PLAN
This is an open label, non-randomized, single arm Phase IV study in patients 70 years of age 
or older with stage IV or recurrent Non-Small Cell Lung Cancer whose tumors harbor 
common EGFR mutations. A total of approximately 25 patients will be entered into the trial.
After completion of the screening assessments, eligible patients will be treated with a starting 
dose of 30 mg afatinib daily as monotherapy. The dose may be reduced dependent on the AE 
profile of the individual patient and concomitant medication. See Section 4.4 on afatinib dose 
modification.
The patient participation in the trial is considered to be concluded when the follow-up visit is 
complete. For patients that agree to be followed, vital status will be collected every 3 months 
until the end of the trial.  The end of the trial is defined approximately one year after the last 
patient has entered the study.
The diagram below depicts the stages of a patient’s participation in this protocol:

3.2
DISCUSSION OF TRIAL DESIGN, INCLUDING THE CHOICE OF 
CONTROL GROUP
This trial is a single arm, open-label uncontrolled study.  Treatment will be administered in 
courses of 28 days.  The starting dose of afatinib will be 30 mg daily.  Dose reductions will 
be permitted as described in Section 4.4.1.
3.3
SELECTION OF TRIAL POPULATION
Elderly patients determined to have the common EGFR mutations Del 19 and L858R as part 
of standard of care testing will be eligible to be screened for participation in this trial. It is 
foreseen that approximately 25 patients will be treated at approximately 15 to 20 study sites 
in the US. The rate of enrolment will vary by study site, but is expected to be approximately 1
to 2 patients per site. Additional sites may be added if necessary. Given changes in the 
treatment landscape and ability to recruit patients within the study population, study 
discontinuation prior to meeting expected enrollment goals may be considered as described in 
Section 3.3.4.2.
A log of all patients included into the study (i.e. having given informed consent) will be 
maintained in the ISF at the investigational site irrespective of whether they have been treated 
with study drug or not.

4.1.2
Method of assigning patients to treatment groups
This is a single-arm non randomized study. Patients who have given their written informed 
consent will be enrolled sequentially on a first come first enrolled basis and will be registered 
in the trial. Patients who meet all eligibility criteria will be entered into the study and the start 
of treatment will be documented by the investigator. The trial will continue to enroll patients 
until the goal of approximately 25 patients entered into the study is reached.

afatinib in this vulnerable patient population (elderly) reflects actual clinical practice.
The daily dose will be modified following careful monitoring of a patient’s drug-related 
adverse events. Refer to Section 4.4 for dose reductions to be made in response to the 
occurrence of adverse events. Dose escalation will not be allowed during this study.
4.1.4
Drug assignment and administration of doses for each patient
Patients will take a single oral dose of afatinib each day starting at a dose of 30 mg 
continuously. The dose of afatinib must be reduced if certain adverse events occur (see 
Section 4.4).

Afatinib should be taken at approximately the same time each day without food (at least one 
hour before a meal or at least two hours after a meal).  
Missed doses of afatinib can be made up within 12 hours of the scheduled time.  Otherwise, 
the dose must be skipped and patients should take the next scheduled dose at the usual time. 
Patients with emesis must not take a replacement dose.
If dosing of whole tablets is not possible, afatinib tablets can also be dispersed in
approximately 100 ml of non-carbonated drinking water. No other liquids should be used. 
The tablet should be dropped in the water, without crushing it, and occasionally stirred for up 
to 15 min until the tablet is broken up into very small particles. The dispersion should be 
drunk immediately. The glass should be rinsed with approximately 100 ml of water which 
should also be drunk. The dispersion can also be administered through a naso-gastric tube. 
Afatinib will be prescribed by the investigator and may be dispensed either by the 
investigator, site staff or affiliated pharmacy via Interactive Response Technologies (IRT) at 
the beginning of each treatment course.  For administrative purposes, a treatment course is 
defined as 28 days.  Treatment will start when the patient takes the first dose of afatinib 
(Course 1 Day 1) and continue until the criteria for stopping trial medication in Section 
3.3.4.1 are met. 
4.1.5
Blinding and procedures for unblinding
4.1.5.1
Blinding
This open-label, single-arm study will be handled in an open fashion throughout, i.e., also for 
the purpose of data cleaning and preparation of the analysis. No blinding is necessary in this 
trial, because all patients receive the same treatment.

Not applicable
4.1.6
Packaging, labelling, and re-supply
For details of packaging and the description of the label, refer to the product package insert 
provided in the ISF.
Afatinib will be supplied as film-coated tablets. Available dosage strengths will be 20 mg and 
30 mg.
Medication numbers which will be recorded by the site in the eCRF (Electronic Case Report 
Form) are used for tracking purposes only. 
As study medications will be commutable between studies 1200.208 and 1200.209, both 
study numbers will be pre-printed on the study medication labels.  Upon enrolment at Visit 1,

IRT will issue a report showing the study number and patient number for each patient.  The 
report should be filed in the ISF.
4.1.7
Storage conditions
Drug supplies, should be maintained according to the current drug label, must be kept in a 
secure, limited access storage area under the storage conditions defined on the label 
instructions. Where necessary, temperature logs must be maintained to make certain that the 
drug supplies are stored at the correct temperature. If storage temperature is out of range at 
any time, this has to be reported in the ISF and the sponsor must be notified.
Afatinib must be stored in the original package in order to protect from light. Film-coated 
tablets are humidity-sensitive; therefore, bottles must be kept tightly closed to protect from 
moisture.
4.1.8
Drug accountability
The investigator or delegate (e.g. pharmacist or investigational drug storage manager) will 
utilize sponsor provided afatinib when the following requirements are fulfilled:

Approval of the study protocol by the institutional review board (IRB) / ethics 
committee, 

Availability of a signed and dated clinical trial contract between the sponsor and the 
Head of Trial Centre,

Approval/notification of the regulatory authority, e.g. competent authority,

Availability of the curriculum vitae of the principal investigator,

Availability of a signed and dated clinical trial protocol (CTP) or immediately 
imminent signing of the clinical trial protocol, 

Availability of the proof of a medical licence for the principal investigator (if 
applicable).

Availability of the Form 1572 (if applicable)
The Investigator or delegate investigational drug storage manager must maintain records of 
the product’s delivery to the trial site, the inventory at the site, the use by
each patient, and the return to the Sponsor or alternative disposal of unused products.
These records will include dates, quantities, batch / serial numbers, expiry (‘use- by’) dates,
and the unique code numbers assigned to the investigational product and trial patients. The
Investigator / Pharmacist / investigational drug storage manager will maintain records that
document adequately that the patients were provided the doses specified by the CTP and
reconcile all investigational products received from the Sponsor. At the time of return to the
Sponsor, the Investigator / Pharmacist / investigational drug storage
manager must verify that all unused or partially used drug supplies have been returned by the
clinical trial patient and that no remaining supplies are in the Investigator’s possession.

4.2
CONCOMITANT THERAPY, RESTRICTIONS, AND RESCUE 
TREATMENT
4.2.1
Rescue medication, emergency procedures, and additional treatments
4.2.1.1
Rescue medication
Rescue medications to reverse the actions of afatinib are not available. There is no specific 
antidote for over dosage with afatinib. Potential adverse events should be treated 
symptomatically. Common adverse events of treatment with afatinib with specified 
management recommendations and/or requirements include diarrhoea, and rash/acne. To 
improve tolerability and the probability of clinical benefit, patients should receive prompt and 
appropriate supportive care at the first signs of symptoms. Suggested treatments for AEs are 
described in Section 4.4.2.
4.2.1.2
Emergency procedures
Careful assessment of all patients with an acute onset and/or unexplained worsening of 
pulmonary symptoms (dyspnoea, cough, fever) should be performed to exclude ILD. Afatinib 
should be interrupted pending investigation of these symptoms. If interstitial lung disease is 
diagnosed, study drug must be permanently discontinued and appropriate treatment instituted 
as necessary. 
Patients who present with symptoms of keratitis, such as acute or worsening eye 
inflammation, lacrimation, light sensitivity, blurred vision, eye pain and/or red eye should be 
referred promptly to an ophthalmic specialist. If a diagnosis of ulcerative keratitis is 
confirmed, treatment with afatinib should be interrupted or discontinued. If keratitis is 
diagnosed, the benefits and risks of continuing treatment with afatinib should be carefully 
considered. Afatinib should be used with caution in patients with a history of keratitis, 
ulcerative keratitis or severe dry eye. Contact lens use is a risk factor for keratitis and 
ulceration.
Dermatologic adverse events and diarrhoea are the most common side-effects associated with 
treatment with afatinib. Treatment of these side-effects should be proactive and should be 
started as early as possible after onset of symptoms.
4.2.1.3
Additional treatments
Concomitant medications or therapy to provide adequate supportive care may be given as 
clinically necessary. 
After study enrollment, palliative radiotherapy may be given for bone pain or for other 
reasons (e.g. bronchial obstruction, skin lesions), provided that the total dose delivered is in a 
palliative range according to institutional standards. The irradiated area cannot be used for 
tumor response assessment. During palliative radiotherapy, study treatment should be delayed 
and may be resumed once the patient has recovered from any radiation-associated toxicity.  If 
medication is interrupted for more than 14 days, the decision to continue will be made by the 
BI clinical monitor in agreement with the investigator.  Patients who are dose interrupted for

>28 days due to palliative radiotherapy must be permanently discontinued from study 
medication.
All concomitant therapy, including anaesthetic agents, vitamins, homeopathic/herbal 
remedies, nutritional supplements, must be recorded in the eCRF during the screening and 
treatment period, starting from the date of signature of informed consent, and ending at the 
EOT (end of treatment) visit. After the EOT visit, only concomitant therapy indicated for 
treatment of an AE has to be reported. 
In case of major surgery (as judged by the investigator), it is recommended to stop treatment 
with afatinib around one week prior to the surgery, and to restart treatment after complete 
wound healing. If afatinib is interrupted for more than 14 days, the decision to continue will 
be made by the BI Clinical Monitor in agreement with the investigator.
4.2.2
Restrictions
4.2.2.1
Restrictions regarding concomitant treatment
Concomitant medications or therapy to provide adequate supportive care may be given as 
clinically necessary. 
Palliative radiotherapy may be given as described in Section 4.2.1.3.
Additional experimental anti-cancer treatment and/or standard chemo-, immunotherapy, 
hormone treatment (with the exception of megestrol acetate and use of anti-androgens and/or 
gonadorelin analogues for treatment of prostate cancer), or radiotherapy (other than palliative 
radiotherapy for symptom control) is not allowed concomitantly with the administration of 
afatinib. 
Afatinib is a substrate of the P-gp transporter. Caution should be exercised when combining 
afatinib with P-gp modulators.  For a list of potent P-gp inhibitors and inducers see Appendix 
10.2.
4.2.2.2
Restrictions on diet and life style
Patients should be advised to avoid any foods known to aggravate diarrhoea.
To prevent skin related adverse events it is recommended to avoid intense irradiation with 
UV light and harsh detergents, see also Section 4.4.2.
4.2.2.3
Men capable of fathering a child and pregnancy prevention
Men who are capable of fathering a child and whose partners have child bearing potential
must use adequate contraception throughout the trial (from screening until 28 days after last 
dose of trial medication). 
Acceptable methods of contraception include surgical sterilisation and double barrier method, 
and must be in accordance with local regulations where applicable. Double barrier method of

contraception is defined as two barrier methods used simultaneously each time the patient has 
intercourse. Accepted barrier methods include diaphragm, female condom, cervical cap, male 
condom and intrauterine device (IUD) (the diaphragm and cervical cap must be used in 
conjunction with spermicidal jelly/cream). Those with partners using hormonal 
contraceptives must also be using an additional approved method of contraception (as 
described above).  Natural “rhythm” and spermicidal jelly/cream are not acceptable methods 
of contraception.
Pregnancies that result from a male participating in this trial must be reported following BI 
internal SOP using the pregnancy monitoring form (refer to ISF).   
4.3
TREATMENT COMPLIANCE
The study medication will be given in accordance with the protocol and the instructions of a 
site investigator. 
The appropriate number of afatinib tablets for 28 days of treatment will be provided to 
patients to be self-administered at home.
Patients will be asked to bring the remaining trial medication to the investigator site for a 
compliance check according to the Flowchart. The remaining film-coated tablets will be 
counted by the investigator/site staff and recorded at the investigator site. Discrepancies 
between the number of tablets remaining and the calculated number of tablets the patients 
should have taken must be documented and explained. At the end of each 28 day period, any 
remaining medication will be collected. If the patient is eligible for further treatment, a new 
bottle of study medication must be dispensed. 
Patient’s repeatedly missing scheduled on-treatment study visits, unless due to exceptional 
circumstances, should be discussed with the BI trial monitor and be evaluated for 
compliance. A maximum of 25% of the dispensed afatinib doses may be missed for other 
reasons than drug-related AEs. Patients who miss afatinib treatment more frequently are 
considered non-compliant.  
The investigator and/or the sponsor can withdraw a patient from the study in the event of 
serious and persistent non-compliance which jeopardizes the patient’s safety or render study 
results for this patient unacceptable. 
4.4
MANAGEMENT OF DOSE REDUCTION AND EXPECTED ADVERSE 
EVENTS
4.4.1
Management of dose reduction for afatinib
Afatinib treatment related toxicities will be managed by treatment interruptions and 
subsequent dose reductions according to the schedule described in Table 4.4.1: 1. Dose 
reductions will apply to individual patients only. Once the dose has been reduced, it cannot 
be increased later.

Interstitial Lung Disease (ILD) should be considered if a patient develops acute or worsening 
of respiratory symptoms in which case treatment should be interrupted pending evaluation. If 
ILD is diagnosed, afatinib should be discontinued and appropriate treatment initiated as 
necessary.
In the event of any unrelated adverse events, the investigator may choose to interrupt the 
medication for up to 14 days, but no dose reduction should occur.  If the medication is 
interrupted for more than 14 days for any reason, the decision to continue with afatinib will 
be made by the BI clinical monitor in agreement with the investigator.
4.4.2
Management of expected adverse events
4.4.2.1 Management of diarrhoea and hydration status following treatment with afatinib
Diarrhea occurs at a high frequency and generally begins within 2 weeks of exposure to 
afatinib. Although usually mild to moderate, diarrhea may lead to dehydration and require 
treatment modification or discontinuation, so early management is essential (Table 4.4.1:1). 
At the time of initiation of treatment with afatinib, patients should be given a supply of 
loperamide to keep with them at all times or access to loperamide should be confirmed; and 
patients should be counselled on the appropriate use. 
Patients must be advised to drink an adequate amount of fluid to make up for the fluid lost 
through diarrhea.

clinical experience, early involvement of a dermatologist should be considered (adapted from 
R11-0826).
Table 4.4.2.2: 1 General recommendation for prophylaxis while receiving afatinib
Personal hygiene
Use of gentle soaps and shampoos for the body, e.g. pH5 neutral bath and 
shower formulations and tepid water.
Use of very mild shampoos for hair wash.
Only clean and smooth towels are recommended because of potential risk of 
infection. The skin should be patted dry after a shower, whereas rubbing the skin 
dry should be avoided.
Fine cotton clothes should be worn instead of synthetic material.
Shaving has to be done very carefully.
Manicure, i.e. cutting of nails, should be done straight across until the nails no 
longer extend over the fingers or toes. Cuticles are not allowed to be trimmed 
because this procedure increases the risk of nail bed infections
Sun protection
Sunscreen should be applied daily to exposed skin areas regardless of season. 
Hypoallergenic sunscreen with a high SPF (at least SPF30, PAPA free, 
UVA/UVB protection), preferably broad spectrum containing zinc oxide or 
titanium dioxide are recommended
Patients should be encouraged to consequently stay out of the sun.
Protective clothing for sun protection and wearing a hat should be recommended.
Moisturizer treatment
It is important to moisturize the skin as soon as anti-EGFR therapy is started.
Hypoallergenic moisturizing creams, ointments and emollients should be used 
once daily to smooth the skin and to prevent and alleviate skin dryness. 
Note: avoid greasy creams (e.g. petrolatum, soft paraffin, mineral oil based) and 
topical acne medications
Prevention of paronychia 
Patients should keep their hands dry and out of water if ever possible.
They should avoid friction and pressure on the nail fold as well as picking or 
manipulating the nail.
Topical application of petrolatum is recommended around the nails due to its 
lubricant and smoothing effect on the skin.

4.4.2.3
Management of mucositis/stomatitis 
General and grade specific recommendations are described in Table 4.4.2.3:1. For dose 
adjustment refer to Section 4.4.1 and for restrictions on concomitant therapies refer to Section 
4.2.2.
Treatment is supportive and aimed at symptom control. These may include atraumatic 
cleansing and rinsing with non-alcoholic solutions such as normal saline, diluted salt and 
baking soda solution (e.g. one-half teaspoonful of salt and one teaspoon of baking soda in one 
quart of water every four hours); avoidance of agents containing iodine, thyme derivatives 
and prolonged use of hydrogen peroxide; dietary manoeuvres such as promotion of soft, non-
irritating foods like ice-creams, mashed/cooked vegetables, potatoes and avoidance of spicy, 
acidic or irritating foods such as peppers, curries, chillies, nuts and alcohol. If the patient is 
unable to swallow foods or liquids, parenteral fluid and/or nutritional support may be needed. 
Examples of some of the agents suggested in Table 4.4.2.3:1 include: topical analgesics –
viscous lidocaine 2%; mucosal coating agents - topical kaolin/pectin; oral antacids, 
maltodextrin, sucralfate; topical antifungals – nystatin suspension (adapted from P11-09424).

VARIABLES AND THEIR ASSESSMENT
There are three categories of endpoints in this trial: 1) the primary endpoint, 2) secondary 
endpoints and 3) other endpoints. The primary endpoint of this study is a safety endpoint, the 
occurrence of AEs leading to the dose reduction of afatinib. The secondary endpoints are 
also safety endpoints. The category of “other endpoints” includes specific safety and efficacy 
endpoints.

5.2
SAFETY
5.2.1
Endpoints of safety
The primary endpoint of the study is the occurrence of AEs leading to dose reduction of 
afatinib. Patients without AEs leading to dose reduction of afatinib will be considered as “no” 
for the primary endpoint. No confirmatory analysis is planned (i.e. no formal hypothesis 
testing will be performed.)
The secondary endpoints of the study are:

Occurrence of CTCAE grade≥3 diarrhea

Occurrence of CTCAE grade≥3 rash/acne+ 

Occurrence of CTCAE grade ≥3 stomatitis+

Occurrence of CTCAE grade ≥3 -)(*%6>:$)H

Time to first dose reduction of afatinib caused by AEs, defined as time from the date 
of the first administration of afatinib to the first dose reduction of afatinib caused by 
AEs.
In the study, MedDRA preferred terms that describe AEs of similar nature will be grouped 
together as “grouped term” to ensure that important events will not be underestimated. These 
grouped terms are flagged by a ‘+’.
Endpoints for safety belonging to the category of ‘other endpoints’ are:

Adverse events evaluated according to the National Cancer Institute (NCI) Common 
Terminology Criteria for Adverse Events (CTCAE) version 4.0 (R12-2532).
5.2.2
Assessment of adverse events
5.2.2.1
Definitions of adverse events
Adverse event
An adverse event (AE) is defined as any untoward medical occurrence, including an 
exacerbation of a pre-existing condition, in a patient in a clinical investigation who received a 
pharmaceutical product. The event does not necessarily have to have a causal relationship 
with this treatment.
Serious adverse event

2018 Boehringer Ingelheim International GmbH or one or more of its affiliated companies. All rights reserved.
This document may not - in full or in part - be passed on, reproduced, published or otherwise used without prior written permission.
A serious adverse event (SAE) is defined as any AE which results in death, is immediately 
life-threatening, results in persistent or significant disability / incapacity, requires or prolongs 
patient hospitalisation, is a congenital anomaly / birth defect, or is to be deemed serious for 
any other reason if it is an important medical event when based upon appropriate medical 
judgement which may jeopardise the patient and may require medical or surgical intervention 
to prevent one of the other outcomes listed in the above definitions.
Intensity of adverse event
The intensity of adverse events should be classified and recorded according to the Common 
Terminology Criteria for Adverse Events (CTCAE) version 4.0 and recorded in the eCRF.
Causal relationship of adverse event
Medical judgment should be used to determine the relationship, considering all relevant 
factors, including pattern of reaction, temporal relationship, de-challenge or re-challenge, 
confounding factors such as concomitant medication, concomitant diseases and relevant 
history. Assessment of causal relationship should be recorded in the case report forms (CRF). 
Yes:
There is a reasonable causal relationship between the investigational product 
administered and the AE. 
No:
There is no reasonable causal relationship between the investigational product 
administered and the AE. 
Worsening of the underlying disease or other pre-existing conditions
Disease Progression in oncology trials is a study endpoint for analysis of efficacy. Disease 
progression is exempted from reporting as a (S)AE. Progression of the patient's underlying 
malignancy will be recorded in the appropriate pages of the (e)CRF as part of efficacy data 
collection. Death due to disease progression is to be recorded on the appropriate (e)CRF page 
and not on a SAE form. 
Examples of exempted events of PD are: Progression of underlying malignancy (Progressive 
disease PD): if PD is clearly consistent with the suspected progression of the underlying 
malignancy as defined by the respective response criteria. 
• Hospitalization/Procedures due solely to the progression of underlying malignancy (PD) 
• Clinical symptoms and/or signs of progression (with or without confirmation by objective 
criteria e.g. imaging, clinical measurement): if the symptom can exclusively be determined to 
be due to the progression of the underlying malignancy and does meet the expected pattern of 
progression for the disease under study. 
When there is evidence suggesting a causal relationship between the drug and the progression 
of the underlying disease, the event must be reported as (S)AE on the eCRF and SAE form. 
Worsening of other pre-existing conditions will be recorded as an (S)AE in the eCRF and 
SAE form (if applicable).

Changes in vital signs, ECG, physical examination, and laboratory test results
Changes in vital signs, ECG, physical examination and laboratory test results will be 
recorded as an (S)AE in the eCRF, if they are judged clinically relevant by the investigator.
Adverse Event of Special Interests (AESIs)
No AESIs have been defined for this trial.
Expected Adverse Events
For expected (listed) AEs of afatinib, see the current version of the IB (Investigator’s Brochure) 
(U03-3218-13).
5.2.2.2
Adverse event and serious adverse event reporting
All adverse events, serious and non-serious, occurring during the course of the clinical trial 
(i.e., from signing the informed consent onwards through the follow-up period of 28 days 
after the last drug administration, Table 5.2.2.2:1) will be collected, documented and reported 
to the sponsor by the investigator on the appropriate eCRFs / SAE reporting forms. Reporting 
will be done according to the specific definitions and instructions detailed in the ‘Adverse 
Event Reporting’ section of the Investigator Site File. 
For each adverse event, the investigator will provide the onset date, end date, intensity, 
treatment required, outcome, seriousness, and action taken with the investigational drug. The 
investigator will determine the relationship of the investigational drug to all AEs as defined in 
Section 5.2.2.1. 
The Residual Effect Period (REP), defined as the period of time after the last dose of 
medication when measureable drug levels or pharmacodynamic effects are still likely to be 
present, is 28 days for Afatinib. All events reported within 28 days of the last study 
medication will be considered on-treatment. 
The investigator does not need to actively monitor patients for adverse events once the 
clinical trial has ended. However, if the investigator becomes aware of an SAE that occurred 
after the patient has completed the clinical trial, it should be reported by the investigator to 
the sponsor if considered relevant by the investigator.
All AEs, including those persisting after end of study treatment must be followed up until 
they have resolved or have been sufficiently characterized or the principal investigator 
decides to not further pursue them.

deaths.
For treated patients; From signing of 
informed consent to the end of the follow-up 
visit (28 days after last trial drug 
administration)
Report all AEs and SAEs regardless of 
relatedness or whether the trial drug is 
administered. This includes all deaths.
After the 28 day followup visit until vital 
status followup (VS) is completed
Report all related SAEs. 
After the patient has completed the study
Active monitoring for adverse events is not 
required. If the investigator becomes aware of 
an SAE that occurred after the patient has 
completed the clinical trial it should be 
reported to the sponsor if considered relevant 
by the investigator.
If not stipulated differently in the ISF, the investigator must report the following events using
the SAE form via fax immediately (within 24 hours) to the sponsor: SAEs and non-serious 
AEs relevant to an SAE. The same timeline applies if follow-up information becomes 
available. In specific occasions, the investigator could inform the sponsor via telephone. This 
does not replace the requirement to complete and fax the BI SAE form.
BI has set up a list of AEs which are defined to be always serious. In order to support the 
investigator with the identification of these “always serious adverse events”, if a non-serious 
AE is identified to be serious per BI definition, a query will be raised. The investigator must 
verify the description and seriousness of the event.  If the event description is correct, the 
item “serious” needs to be ticked and an SAE has to be reported in expedited fashion 
following the same procedure as above.
The list of these adverse events can be found via the Remote Data Capture (RDC) system.
With receipt of any further information to these events, a follow-up SAE report has to be 
provided. SAEs and non-serious AEs must include a causal relationship assessment made by 
the investigator.
The SAE form is to be forwarded to the defined unique entry point identified for the BI OPU 
(operative unit) (country-specific contact details will be provided in the Investigator Site 
File). This immediate report is required irrespective of whether the investigational product 
has been administered or not and irrespective of causal relationship. It also applies if new 
information to existing SAEs becomes available. 
Pregnancy
In this study, pregnancy is not expected to occur in female participants with the age of 70 
years or older. In rare cases, pregnancy might occur in a female partner of a male participant
with drug exposure to afatinib; in which case, pregnancy must be reported following BI 
internal SOP using the pregnancy monitoring form (refer to ISF).

as part of routine clinical care and clinically significant results are found, this will be 
documented in accordance with the adverse event process. 
5.2.5
Assessment of other safety parameters
5.2.5.1 Physical examination, vital signs, height and weight
A full physical exam must include cardiopulmonary examination, examination of the regional 
lymph nodes, and examination of the abdomen and an assessment of the mental and 
neurological status. Additional symptoms which have not been reported during a previous 
examination must be clarified. Wherever possible the same investigator should perform this 
examination.
A complete physical examination will be done at Screening, on Day 1 of each treatment 
course and at the End of Treatment visit. A symptom-directed examination is to be performed 
at all other visits. 
5.2.5.2 Vital Signs
Vital sign measurements should include blood pressure [systolic blood pressure, diastolic 
blood pressure], pulse rate, respiratory rate, temperature and measurement of height (in cm, at 
screening) and body weight (in kg at screening and end of trial). Evaluation of the ECOG PS
(see Appendix 10.1) will be performed at the times specified in the Flowchart.

INVESTIGATIONAL PLAN
6.1
VISIT SCHEDULE
Please refer to the Flowchart and Figure 3.1:1 for the visit schedule. All patients are to adhere 
to the visit schedule as specified in the Flow Chart.  
In case a patient misses the scheduled study visit but reports to the investigative site before 
the next scheduled study visit, the missed visit will be performed.  The current date and 
reason for the delayed visit will be noted in the source documentation.  All subsequent study 
visits should take place at the start of the next treatment course per the flow chart.  In the 
event of any study drug interruption or delay of treatment, the tumour assessment scheduled 
will not be changed.
6.2
DETAILS OF TRIAL PROCEDURES AT SELECTED VISITS
Please refer to the Flowchart and section 5 for details of the procedures performed at each 
visit. 
6.2.1
Screening period
All patients must have documented Deletion 19 and/or L858R EGFR mutation prior to the 
signing of the informed consent. All Screening procedures must be performed within 28 days 
of the first dose of afatinib. Assessments required for study participation which were 
completed as part of Standard of Care before the patient signed the informed consent may be 
used for the screening assessments if they were completed within the allowed timeframe.  
However, presence of Deletion 19 and/or L858R mutation may have been determined prior 
to the 28-day screening window. 
Patients who meet the inclusion criteria and not violate the exclusion criteria at enrolment are 
allowed to take part in this study.
6.2.2
Treatment periods
All patients will receive continuous daily treatment with afatinib until the criteria for stopping 
medication are met (Section 3.3.4.1). For administrative purposes, treatment is divided into 
courses, which are each 4 weeks (28 days) in duration. 
During the treatment phase, visits should be performed as scheduled whenever possible, but 
within the visit window. Deviation in scheduling for administrative purpose would be 
acceptable upon agreement between the investigator and the sponsor.
6.2.3
End of treatment visit
End of treatment visit should be performed within 7 calendar days after permanent 
discontinuation of treatment, regardless of the reason. If the decision to discontinue study 
treatment is taken during a scheduled visit, the EOT visit should be performed instead of the 
scheduled visit.

STATISTICAL METHODS AND DETERMINATION OF
SAMPLE SIZE
7.1
STATISTICAL DESIGN – MODEL
This study is an open-label, single arm study in elderly NSCLC patients with common EGFR 
mutations treated with afatinib.
7.2
NULL AND ALTERNATIVE HYPOTHESES
No formal hypothesis testing will be performed since this is a single arm, uncontrolled study.
This is an exploratory trial and all the statistical analyses will be descriptive.
7.3
PLANNED ANALYSES
All patients who receive at least one dose of afatinib will be included in the treated set.  The 
analyses of safety and efficacy will be performed on the treated set.
Corresponding to the three categories of endpoints, there are three categories of analyses in 
this trial: 1) the primary analysis, 2) secondary analysis, and 3) other analyses. The primary 
and secondary analyses are safety analyses. The category “Other analyses” includes both 
safety and efficacy analyses.
7.3.1
Primary analyses
As the primary endpoint is a safety endpoint, these analyses are described in Section 7.3.3.
7.3.2
Secondary and other analyses
7.3.2.1 Secondary analyses
The secondary safety analyses are described in Section 7.3.3.

Tables that describe the frequency, time to onset, and clinical consequences will be produced 
for:

CTCAE grade ≥ 3 diarrhoea

CTCAE grade ≥3 rash/acne+

CTCAE grade ≥3 stomatitis+

CTCAE grade≥ 3 paronychia+
Time to first dose reduction of afatinib caused by AEs is defined as follows: 
For patients with AEs leading to dose reduction: 
•
Time _1st_dose_reduction [days] = date of 1st dose reduction – (date of start 
treatment)+1
For patients without AEs leading to dose reduction: 
•
Time _1st_dose _reduction (censored)[days]=date of last intake of afatinib –
(date of start treatment) +1
The time to first dose reduction of afatinib caused by AE’s will be described by Kaplan-
Meier estimates and curve.
7.3.3.3
Other analyses
Standard tabulations arranged by MedDRA SOC and PT will include: 

The overall incidence and intensity of adverse events

AE judged to have been related to afatinib

AE leading to permanent treatment discontinuation

Drug related AE leading to permanent treatment discontinuation

SAE
These standard tables will be supplemented with tables in which MedDRA SMQ and HLT
(with some modifications) will be used to group MedDRA PT for the following:

rash/acne+

stomatitis+

conjunctivitis+

paronychia+

fatigue+
Tables that describe the frequency, intensity, time to onset, and clinical consequences will be

Primary laboratory tests
Primary laboratory tests are defined as:

Low values (-): haemoglobin, total WBC, platelets, neutrophils, lymphocytes, 
potassium, magnesium, sodium, and GFR

High values (+): AST, ALT, Alkaline Phosphatase, aPTT, INR, Creatinine, Total 
Bilirubin,  and CPK
The following analyses will be presented for the primary laboratory tests:

descriptive statistics at each planned assessment 

frequency of patients with transitions in CTCAE grade from baseline to worst and last 
values during treatment

frequency of patients with possible clinically significant abnormalities
Possible clinically significant abnormalities are defined as CTCAE grade of 2 or greater, with 
an increase of at least one grade from baseline.
7.3.4
Interim analyses
No interim analyses are planned for this study.
7.4
HANDLING OF MISSING DATA
Handling of missing data will be defined in the TSAP. The category missing will be 
displayed in the frequency tables only if there are actually missing values.
7.5
RANDOMISATION
No randomization is necessary since this is a single arm study.
7.6
DETERMINATION OF SAMPLE SIZE
In the general population of the LUX-Lung 3 study, approximately 60% of the patients 
experienced AEs leading to dose reduction of afatinib. For 25 patients and a 60% dose 
reduction rate (caused by AEs), the 95% CI half-width for the dose reduction rate would be 
19.2% based on a normal approximation, resulting in a two-sided, 95% confidence interval of
(40.8%, 79.2%).  If a lower dose reduction rate of 50% is observed, the resulting 2-sided, 
95% confidence interval would be (30.4%, 69.6%). Similarly, if a higher dose reduction rate 
of 70% is observed the 2-sided, 95% confidence interval would be (52.0%, 88.0%).

INFORMED CONSENT, DATA PROTECTION, TRIAL 
RECORDS
The trial will be carried out in compliance with the protocol, the principles laid down in the 
Declaration of Helsinki, in accordance with the ICH Harmonised Tripartite Guideline for 
Good Clinical Practice and relevant BI Standard Operating Procedures (SOPs). Standard 
medical care (prophylactic, diagnostic and therapeutic procedures) remains in the 
responsibility of the treating physician of the patient.
The investigator should inform the sponsor immediately of any urgent safety measures taken 
to protect the study subjects against any immediate hazard, and also of any serious breaches
of the protocol/ICH GCP.
The rights of the investigator and of the sponsor with regard to publication of the results of 
this trial are described in the investigator contract. As a general rule, no trial results should be 
published prior to finalisation of the Clinical Trial Report.
8.1
STUDY APPROVAL, PATIENT INFORMATION, AND INFORMED 
CONSENT
This trial will be initiated only after all required legal documentation has been reviewed and 
approved by the respective Institutional Review Board (IRB) / Independent Ethics Committee 
(IEC) and competent authority (CA) according to national and international regulations. The 
same applies for the implementation of changes introduced by amendments.
Prior to patient participation in the trial, written informed consent must be obtained from each 
patient (or the patient’s legally accepted representative) according to ICH GCP and to the 
regulatory and legal requirements of the participating country. Each signature must be 
personally dated by each signatory and the informed consent and any additional patient-
information form retained by the investigator as part of the trial records. A signed copy of the 
informed consent and any additional patient information must be given to each patient or the 
patient’s legally accepted representative.
The patient must be informed that his/her personal trial-related data will be used by 
Boehringer Ingelheim in accordance with the local data protection law. The level of 
disclosure must also be explained to the patient.
The patient must be informed that his / her medical records may be examined by authorised 
monitors (CML/CRA) (Local Clinical Monitor / Clinical Research Associate ) or Clinical 
Quality Assurance auditors appointed by Boehringer Ingelheim, by appropriate IRB / IEC
members, and by inspectors from regulatory authorities.

auditor will have access to all medical records, the investigator’s trial-related files and 
correspondence, and the informed consent documentation of this clinical trial.
8.3
RECORDS
Case Report Forms for individual patients will be provided by the sponsor via remote data 
capture. See Section 4.1.5.2 for rules about emergency code breaks. For drug accountability, 
refer to Section 4.1.8.
8.3.1
Source documents
Source documents provide evidence for the existence of the patient and substantiate the 
integrity of the data collected. Source documents are filed at the investigator’s site.
Data entered in the eCRFs that are transcribed from source documents must be consistent 
with the source documents or the discrepancies must be explained. The investigator may need 
to request previous medical records or transfer records, depending on the trial; also current 
medical records must be available.
For eCRFs all data must be derived from source documents.
8.3.2
Direct access to source data and documents
The investigator / institution will permit trial-related monitoring, audits, IRB / IEC review 
and regulatory inspection, providing direct access to all related source data / documents. 
eCRFs and all source documents, including progress notes and copies of laboratory and 
medical test results must be available at all times for review by the sponsor’s clinical trial 
monitor, auditor and inspection by health authorities (e.g. FDA). The CRA / on site monitor 
and auditor may review all eCRFs, and written informed consents. The accuracy of the data 
will be verified by reviewing the documents described in Section 8.3.1.
8.4
LISTEDNESS AND EXPEDITED REPORTING OF ADVERSE EVENTS
8.4.1
Listedness
To fulfil the regulatory requirements for expedited safety reporting, the sponsor evaluates 
whether a particular adverse event is "listed", i.e. is a known side effect of the drug or not.
Therefore a unique reference document for the evaluation of listedness needs to be provided. 
For afatinib this is the currently approved drug label. The current versions of these reference 
documents are to be provided in the ISF. No AEs are classified as listed for study design, or 
invasive procedures.
8.4.2
Expedited reporting to health authorities and IECs/IRBs
Expedited reporting of serious adverse events, e.g. suspected unexpected serious adverse 
reactions (SUSARs) to health authorities and IECs/IRBs, will be done according to local 
regulatory requirements. Further details regarding this reporting procedure are provided in the 
Investigator Site File.
