• Treatments: Afatinib; Albumin-Bound Paclitaxel; Gemcitabine; Paclitaxel

Criteria

Inclusion Criteria:

1. Adult patients ≥ 18 years of age and ≤ 75 years

2. Histologically (not cytologically) confirmed diagnosis of metastatic pancreatic ductal adenocarcinoma (PDAC) [Stage IV according to UICC TNM edition 7 of 2009: each T, each N, M1]

3. No option for surgical resection or radiation in curative intent

4. At least one unidimensionally measurable tumor lesion (according to RECIST 1.1)

5. ECOG performance status 0 - 1

6. Life expectancy at least 3 months

7. Adequate hepatic, renal and bone marrow function, defined as:

• Absolute neutrophil count (ANC) ≥ 1.5x109/L

• Haemoglobin ≥ 9 g/dL 9

• Thrombocytes ≥100x10/L

• Total bilirubin ≤ 1.5xULN.

• Patients with a biliary stent may be included provided that bilirubin level after stent insertion decreased to ≤ 1.5 x ULN and there is no cholangitis.

• AST/GOT and/or ALT/GPT ≤ 2.5 x ULN or in case of liver metastasis ≤ 5 x ULN)

• Serum creatinine within normal limits or creatinine clearance ≥60 mL/min/1.73 m2 as calculated by CKD- EPI formula for patients with serum creatinine levels above or below the institutional normal value.

8. Acceptable coagulation studies defined as prothrombin time (or INR) and PTT ≤ 1.5 x ULN

9. Stable/decreasing pain symptoms under pain medication or no pain within the last 2 weeks before first application of study medication (as reported and assessed by the patient).

10. Females of childbearing potential (FCBP) must have a negative highly sensitive serum pregnancy test within 7 days of the first application of study treatment and they must agree to undergo a further pregnancy tests at monthly intervals and at the end of treatment visit and FCBP must either agree to use and be able to take highly effective contraceptive birth control methods (Pearl Index < 1) or agree to practice complete abstinence from heterosexual intercourse during the course of the study and for at least 1 month after last application of study treatment. A female subject following menarche is considered to be of childbearing potential unless she is naturally amenorrhoeic for ≥ 1 year without an alternative medical reason, or unless she is permanently sterile.

11. Males must agree to use condoms during the course of the trial and for at least 6 months after last administration of study drugs or practice complete abstinence from heterosexual intercourse.

13. Patient's legal capacity to consent to study participation

Exclusion Criteria:

1. Locally advanced PDAC without metastasis

2. Evidence of ascites

3. Known metastatic disease to the brain. Brain imaging is required in symptomatic patients to rule out brain metastases, but is not required in asymptomatic patients.

4. Previous palliative chemotherapy or other palliative systemic tumor therapy for metastatic disease of PDAC

5. Previous gemcitabine treatment with exception of gemcitabine treatment applied as monotherapy in the adjuvant setting (after potential curative R0 or R1 resection) and if the adjuvant single-agent gemcitabine chemotherapy was terminated at least 6 months before study entry

6. Previous radiotherapy of PDAC

7. Previous ErbB family directed therapy for PDAC (e. g. erlotinib, cetuximab, trastuzumab, lapatinib)

8. Any major surgery within the last 4 weeks before study entry

9. Clinical significant decrease in performance status within 2 weeks of intended first application of study medication (by medical history)

10. Severe tumor-related cachexia and/or known weight loss >15% within one month before study enrollment

11. Pre-existing polyneuropathy ≥ grade 2 according to CTCAE version 4.03

12. LDH >2.5xULN

13. Significant (≥ 20%) decrease in serum albumin levels within 2 weeks of intended first application of study medication (by medical history)

14. Gastrointestinal disorders that might interfere with the absorption of the study drug and gastrointestinal disorders with diarrhoea as a major symptom (e.g. Crohn's disease, malabsorption), and chronic diarrhoea of any aetiology CTCAE version 4.03 grade ≥ 2

15. Medical history of interstitial lung disease (ILD) or pulmonary fibrosis or severe COPD

16. Liver cirrhosis Child-Pugh other than class A

17. Known coagulopathy or bleeding disorder

18. History of connective tissue disorders (e.g. lupus, scleroderma,arteritis nods)

19. Any other severe concomitant disease or disorder, which could influence patient's ability to participate in the study and his/her safety during the study or interfere with interpretation of study results e.g. active infection, uncontrolled hypertension, clinically significant cardiovascular disease e.g. cerebral vascular accident (≤ 6 months before study start), myocardial infarction (≤ 6 months before study start), unstable angina, heart failure ≥ NYHA functional classification system grade 2, severe cardiac arrhythmia requiring medication, metabolic dysfunction, severe renal disorder.

20. Any other malignancies than PDAC within the last 5 years before study start, except for adequately treated carcinoma in situ of the cervix, basal or squamous cell skin cancer

21. Hypersensitivity to afatinib, nab-paclitaxel, or gemcitabine or to any of the excipients or to compounds with similar chemical or biologic composition

22. Continuing abuse of alcohol,drugs,or medical drugs

23. Pregnant or breast-feeding females or FCBPs unable to either perform highly effective contraceptive measures or practice complete abstinence from heterosexual intercourse
