About

This trial is a single arm open-label, phase II aiming to assess the clinical activity of niraparib in chemotherapy-naïve biomarker-selected pancreatic cancer patients.

Full description

This trial is a single arm open-label, phase II aiming to assess the clinical activity (objective response rate at week16 according to RECIST V1.1) of niraparib in chemotherapy-naïve biomarker-selected pancreatic cancer patients. HR alterations must be confirmed before study drug start: only patients with mutation and/or rearrangement leading to inactivation in at least one of the following genes BARD1, BRCA1, BRCA2, BRIP1, FANCA, FANCD2, FANCL, MRE11, NBN, PALB2, PPP2R2A, RAD51B, RAD51C, RAD51D, RAD54L are eligible. Eligible patients will receive niraparib once daily, per os, continuously until loss of clinical benefit, unacceptable toxicity, death, patient or physician decision to withdraw, or pregnancy, whichever occurs first.

Inclusion criteria

  • Male or female patient ≥18 years of age at time of informed consent form signature.
  • Histologically proven advanced/metastatic PDAC not curable by surgery and/or definitive radiotherapy and not previously exposed to chemotherapy in advanced/metastatic setting. See Note in the full protocol
  • Documented deleterious alteration resulting in inactivation in at least one of the following genes BARD1, BRCA1, BRCA2, BRIP1, FANCA, FANCD2, FANCL, MRE11, NBN, PALB2, PPP2R2A, RAD51B, RAD51C, RAD51D, RAD54L. See Notes in the full protocol
  • Measurable disease at baseline according to RECIST V1.1 (See Section Appendix) See note in the full protocol
  • Avaibility of a representative formalin-fixed paraffin-embedded (FFPE) sample of the primary or metastatic tumor tissue (resection or biopsy) with an associated pathology with the following quality/quantity control criteria: ≥30 % of tumor cells and a tumor surface area ≥ 5mm2.
  • Optional - Tumor lesion visible by medical imaging and accessible to repeatable percutaneous or endoscopic sampling that permits core needle biopsy without unacceptable risk of a significant procedural complications, and suitable for retrieval of a minimum of 4 cores with a needle minimum diameter :16-gauge. See note in the full protocol.
  • Eastern Cooperative Oncology Group (ECOG) Performance Status of 0 or 1 (See Section Appendix)
  • Life expectancy > 16 weeks.

Adequate hematologic and end-organ function, defined by the following laboratory test results, obtained within 7 days prior to C1D1:

Parameters Laboratory Value

  • Absolute neutrophil count ≥ 1.5 109/L
  • Platelets ≥ 100 109/L
  • Hemoglobin ≥ 9 g/dL (without transfusion within 7 d)
  • Serum creatinine OR Creatinine clearance according to CKD-EPI ≥ 30 mL/min/1.73 m2 for patient with creatinine levels > 1.5 ULN

Serum total bilirubin :

300mg initial dosing: ≤ 1.5 x ULN (except for patients with Gilbert disease for whom a total serum bilirubin ≤ 3 x ULN is acceptable) OR Direct bilirubin ≤ ULN for patients with total bilirubin levels > 1.5 x ULN 200mg initial dosing: up to 3 ULN

-- ASAT and ALAT : 300mg initial dosing: ≤ 2.5 x ULN (or up to 5 x ULN in case of liver metastasis or hepatic infiltration) 200mg initial dosing up to 5ULN

  • Resting blood pressure systolic < 140 mmHg and diastolic <90 mmHg.
  • Women patients of child-bearing potential are eligible, provided they have a negative serum or urine pregnancy test within 3 days prior to C1D1, and agrees to use a highly effective contraception (See section appendix) beginning signing the ICF to 6 months after the final dose of study drug.
  • Fertile men must agree to use an effective method of contraception (See section appendix) during the study and for up to 3 months after the last dose of study drug and to not donate sperm during the same period.
  • Patient should understand, sign, and date the written voluntary informed consent form prior to any protocol-specific procedures performed and should be able and willing to comply with study visits and procedures as per protocol.
  • Patients must be covered by a medical insurance.

Exclusion criteria

  • Patients not respecting the requirement for prior and concomitant treatment
  • Inability to swallow capsules (bowel obstruction) or hereditary problems of galactose intolerance, the Lapp lactase deficiency or glucose-galactose malabsorption.
  • Symptomatic, untreated, or actively progressing central nervous system (CNS) metastases. See notes in the full protocol
  • Patients with other malignancy unless this malignancy is not expected to interfere with the evaluation of study endpoints (eg, basal or squamous cell carcinoma of the skin, in-situ carcinoma of the cervix, localized prostate cancer), or with no evidence of disease for ≥ 2 years.
  • Any known history of myelodysplastic syndrome (MDS) or acute myeloid leukemia (AML)
  • History of severe allergic or other hypersensitivity reactions to any component of niraparib.

Patients with:

  • Active hepatitis B (chronic or acute; defined as having a positive hepatitis B surface antigen [HBsAg] test at screening) unless their HBV is stably controlled on nucleoside analogs (eg entecavir or tenofovir) which will be continued for the duration of the study. See note in the full protocol.
  • Active hepatitis C. Patients positive for hepatitis C virus (HCV) antibody are eligible only if PCR is negative for HCV RNA, or
  • HIV infection
  • Prior organ or bone marrow transplant.
  • Evidence of significant uncontrolled concomitant disease that could affect compliance with the protocol or interpretation of results.
  • Pregnant or lactating women.
