En az bir standart tedavi almış, ölçülebilir hastalığı olan, 18 yaş ve üzeri yetişkinler katılıma uygundur. Çalışma Faz 2 aşamasında yürütülmüş ve tamamlanmıştır.

5. Prior administration of at least one standard treatment for primary and/or relapsed malignancy according to current guidelines
6. Eastern Cooperative Oncology Group Performance Status ≤ 1
7. Male or female patient aged ≥ 18, no upper age limit
8. Postmenopausal or evidence of non-childbearing status. For women of childbearing potential: negative urine pregnancy test at baseline and highly effective forms of contraception in place thereafter as well as confirmed negative urine pregnancy test prior to treatment on day 1 of every cycle and at end of treatment period.
Evidence of childbearing potential is defined as:
o Fertile, following menarche and until becoming post-menopausal unless permanently sterile
Postmenopausal or evidence of non-childbearing status is defined as:
1. Amenorrheic for 1 year or more without an alternative medical cause following cessation of exogenous hormonal treatments PLUS Follicle stimulating hormone (FSH) levels in the postmenopausal range in women not using hormonal contraception or hormonal replacement therapy
2. Surgical sterilisation (bilateral oophorectomy, hysterectomy or bilateral salpingectomy)
9. Female patients of child bearing potential and male patients with partners of child bearing potential, who are sexually active, must agree to the use of two highly effective forms of contraception. This should be started from the signing of the informed consent and continue throughout period of taking study treatment and for 1 month (female patients) / 3 months (male patients) after last dose of study drug.
10. Identification of NRG1 rearrangements within NCT/DKTK MASTER (Heidelberg Ethics Committee Reference No.: S-206/2011) or identification of a NRG1 fusion by another method for fusion detection (e.g. gene fusion panel)
11. Adequate bone marrow, renal, and hepatic function defined by laboratory tests within 14 days prior to study treatment:
1. Absolute neutrophil count (ANC) ≥1500 / mm3. (ANC \>1000/mm3 may be considered in special circumstances such as benign cyclical neutropenia as judged by the investigator and in discussion with the sponsor).
2. Platelet count ≥75,000 / mm3.
3. Estimated creatinine clearance \> 45ml / min (according to Crockroft-Gault-formula).
4. Total Bilirubin ≤ 1.5 times upper limit of normal (Patients with Gilbert's syndrome total bilirubin must be ≤4 times institutional upper limit of normal (ULN)).
5. Aspartate amino transferase (AST) or alanine amino transferase (ALT) ≤ three times the ULN (if related to liver metastases ≤ five times ULN).
12. Left ventricular function with resting ejection fraction ≥ 50% or above the LLN.
13. Recovered from any previous therapy related toxicity to ≤Grade 1 at study entry (except for stable sensory neuropathy ≤Grade 2 and alopecia)
14. Written informed consent that is consistent with ICH-GCP guidelines
Exclusion Criteria:
1. Other malignancy within the last 5 years except: adequately treated non-melanoma skin cancer, curatively treated in situ cancer of the cervix, ductal carcinoma in situ (DCIS), Stage 1, grade 1 endometrial carcinoma, or other solid tumours including lymphomas (without bone marrow involvement) curatively treated with no evidence of disease for ≥5 years
2. Concurrent or previous treatment within 4 weeks in another interventional clinical trial with an investigational anticancer therapy
3. Prior treatment with afatinib
4. Hormonal treatment within 2 weeks prior to start of study treatment (continued use of anti-androgens and/or gonadorelin analogues for treatment of prostate cancer permitted)
5. Radiotherapy within 4 weeks prior to randomization , except as follows:
i.) Palliative radiation to target organs may be allowed up to 2 weeks prior to randomisation, and
ii.) Single dose palliative treatment for symptomatic metastasis outside above allowance to be discussed with coordinating investigator/ scientific investigator prior to enrolling.
6. Major surgery within 4 weeks before starting study treatment or scheduled for surgery during the projected course of the study
7. Known hypersensitivity to afatinib or the excipients of any of the trial drugs
8. History or presence of clinically relevant cardiovascular abnormalities such as uncontrolled hypertension, congestive heart failure NYHA classification of ≥ 3, unstable angina or poorly controlled arrhythmia as determined by the investigator. Myocardial infarction within 6 months prior to randomisation.
9. Women of child-bearing potential (WOCBP) and men who are able to father a child, unwilling to be abstinent or use highly effective methods of birth control that result in a low failure rate of less than 1% per year when used consistently and correctly prior to study entry, for the duration of study participation and for 1 month (female patients)/ 3 months (male patients) after last dose of study drug (after EOT).
10. Women who are pregnant, nursing, or who plan to become pregnant while in the trial
11. Any history of or concomitant condition that, in the opinion of the Investigator, would compromise the patient's ability to comply with the study or interfere with the evaluation of the efficacy and safety of the test drug
12. Known pre-existing interstitial lung disease (ILD)
13. Any history or presence of poorly controlled gastrointestinal disorders that could affect the absorption of the study drug (e.g. Crohn's disease, ulcerative colitis, chronic diarrhoea, malabsorption)
14. Leptomeningeal carcinomatosis
15. Patients with brain or subdural metastases are not eligible, unless they have completed local therapy and have discontinued the use of corticosteroids, anti-convulsants or have been on stable dose of corticosteroids for at least 4 weeks before starting study treatment. Any symptoms attributed to brain metastases must be stable for at least 4 weeks before starting study treatment.
16. Persistent toxicity (≥Grade 2 according to Common Terminology Criteria for Adverse Events \[CTCAE\] version 5.0) caused by previous cancer therapy, excluding alopecia

The required washout period prior to starting afatinib is at least five half-lifes.
25. Concomitant use of P-gp-inducers (e.g. rifampicin, carbamazepine, phenytoin, phenobarbital, St. John's wort) The required washout period prior to starting afatinib is at least five half-lifes (e.g. 5 weeks for phenobarbital).
