(1)Age =18 years
(2)Histologically or cytologically confirmed adenocarcinoma of the pancreas.
(3)Advanced stage locally advanced, unresectable (patients that are resectable but refuse the operation are not eligible) or metastatic disease.
(4)Eligible for therapy with gemcitabine / nab-paclitaxel according to standard of care (any palliative therapy line)
(5)Performance score ECOG 0-2
(6)Adequate organ function defined as:
a.Adequate hematologic function (WBC =3000/µL, absolute neutrophil count =1500/µL, platelets =100.000/µL, hemoglobin =8 g/dL)
b.Adequate renal function (estimated glomerular filtration rate =30 mL/min)
c.Adequate liver function (serum bilirubin =1.5 x ULN, AST/ALT =2.5 x ULN, or 5 x ULN if hepatic metastases are present)
d.Prothrombintime (PT) <1.1 ULN, partial thromboplastin time <1.1 ULN, INR <1.1 ULN.
(7)Use of reliable contraception with a Pearl Index <1% (i.e. two independent effective contraceptive methods) during the trial and for two weeks after the last administration of trial medication in men or women of child bearing potential (WOCBP).
(8)Measurable disease according to RECIST 1.1 criteria.
(9)Tumor lesion accessible for a biopsy and patient willing to undergo tumor biopsy.
(10)Available CT scan of thorax and abdomen not older than 28 days before start of treatment (day 1 of cycle 1). Patients that cannot have a CT scan because of medical reasons (e.g. allergy to contrast dye) may be eligible after MRIs as per standard of care to stage the patient and after documented consultation with the sponsor.
(11)Ability to understand character, consequences and requirements of the clinical trial and to comply with the study protocol and dosing regimen.
(1)Presence of brain metastases, unless previously treated and well-controlled for at least 3 months (defined as clinically stable, no edema, no steroids and stable in 2 scans at least 4 weeks apart).
(2)Testing positive against human immunodeficiency virus (HIV) or history thereof
(3)Active hepatitis C virus (HCV) infection (patients with status post-infection after eradication through antiviral therapy are eligible)
(4)Uncontrolled hepatitis B virus (HBV) infection (<3 months of treatment with a nucleotide analogue and/or >100 HBV-DNA particles)
(5)Pre-existing, clinically significant peripheral neuropathy, defined as CTCAE grade 2 or higher neurosensory or neuromotor toxicity, regardless of etiology
(6)History of malignancy other than pancreatic cancer in the last 5 years. Patients with prior history of in situ cancer or basal or squamous cell skin cancer are eligible. Patients with other malignancies are eligible if they were cured by surgery alone or surgery plus radiotherapy and have been continuously disease-free for at least 5 years.
(7)Present treatment with phenprocoumon, warfarin or another coumadine-based anticoagulant.
(8)Active, uncontrolled bacterial, viral, or fungal infection(s) requiring systemic therapy.
(9)Major surgery, other than for diagnostic purposes ((done to obtain a biopsy for diagnosis without removal of an organ), within 4 weeks prior to Day 1 of treatment in this study.
(10)History of allergy or hypersensitivity to any of the study drugs or any of their excipients.
(11)Serious medical risk factors involving any of the major organ systems, or serious psychiatric disorders, which could compromise patient's safety or study data integrity.
(12)Participation in any other interventional clinical protocol or investigational trial.
(13)Unwillingness or inabilty to comply with study procedures.
(14)Therapy with a narrow therapeutic index drug that is substrate of CYP3A, CYP2D6, or CYP2C9 whose dose cannot be appropriately adjusted (see Appendix ?18.1.).*
(15)Therapy with any medications or substances that are inhibitors or inducers of CYP450 3A enzyme(s) * or therapy with medication that is contraindicated when taking Tybost (See appendices ?18.1 and ?18.2)
(16)Pregnancy or lactating
