  4. For patients with prior anthracycline therapy normal cardiac function with LVEF at least 50% must be assessed by quantitative echocardiogram or MUGA scan
  5. Prior Gemcitabine containing chemotherapy is permitted provided that at least 8 weeks have elapsed since the last dose of therapy
  6. ECOG performance status 0-1
  7. At least 18 years old
  8. Measurable disease according to RECIST v 1.1 criteria (in case of tumour debulking - staging CT-scan after surgery)
  9. Able to swallow and retain oral medication
  10. Adequate organ system function as defined in Table 1

Table 1: Definitions for Adequate Organ Function System Laboratory Values Hematologic Absolute neutrophil count (ANC) > = 1.5 X 109/L Hemoglobin1 > = 9 g/dL (5.6 mmol/L) Platelets > = 100 X 109/L Prothrombin time (PT) or international normalized ratio (INR)4 <= 1.2 X upper limit of normal (ULN) Partial thromboplastin time (PTT) <=1.2 X ULN Hepatic2 Total bilirubin <= 1.5 X ULN AST and ALT <= 2.5 X ULN Renal Serum creatinine <= 1.5 mg/dL (133 mol/L)

Calculated creatinine clearance > = 50 mL/min

Urine Protein to Creatinine Ratio (UPC)3 < 1

  1. Subjects may not have had a transfusion within 7 days prior to screening assessment.
  2. Concomitant elevations in bilirubin and AST/ALT above 1.0 x ULN are not permitted
  3. If UPC > = 1, then a 24-hour urine protein must be assessed. Subjects must have a 24-hour urine protein value <1g to be eligible.
  4. Subjects receiving anticoagulant therapy are eligible if their INR is stable and within the recommended range for the desired level of anticoagulation

    • A bilateral tubal ligation
    • Is post-menopausal Subjects not using hormone replacement therapy (HRT) must have experienced total cessation of menses for 1 year and be greater than 45 years in age, OR, in questionable cases, have a follicle stimulating hormone (FSH) value >40 mIU/mL and an estradiol value < 40pg/mL (<140 pmol/L).

Subjects using HRT must have experienced total cessation of menses for >= 1 year and be greater than 45 years of age OR have had documented evidence of menopause based on FSH and estradiol concentrations prior to initiation of HRT

OR

Negative serum pregnancy test of women of childbearing potential performed within 1 week prior to the first dose of study treatment, preferably as close to the first dose as possible, and agrees to use adequate contraception. Acceptable contraceptive methods, when used consistently and in accordance with the product label and the instructions of the physicians are as followed for 14 days before exposure to investigational product, through the dosing period and for at least 21 days after the last dose of investigational product:

  • Complete abstinence from sexual intercourse
  • Oral contraceptive, either combined or progestogen alone
  • Injectable progestogen
  • Implants of levonorgestrel
  • Estrogenic vaginal ring
  • Percutaneous contraceptive patches
  • Intrauterine device (IUD) or intrauterine system (IUS) with a documented failure rate of less than 1% per year
  • Male partner sterilization (vasectomy with documentation of azoospermia) prior to the female subject's entry into the study, and this male is the sole partner for that subject
  • Double barrier method: condom and an occlusive cap (diaphragm or cervical/vault caps) with a vaginal spermicidal agent (foam/gel/film/cream/suppository) Female subjects who are lactating should discontinue nursing prior to the first dose of study drug and should refrain from nursing throughout the treatment period and for 14 days following the last dose of study drug.

Exclusion Criteria:
