Description

Summary

This is an open label, non-randomized, dose escalation and expansion Phase Ib trial to evaluate the safety and recommended phase II dose of the combination of irinotecan and rucaparib.

Official Title

Combination Therapy of Rucaparib and Irinotecan in Cancers With Mutations in DNA Repair

Details

In dose escalation, patients will receive irinotecan and rucaparib. Irinotecan will be given once every 2 weeks (or 3 weeks if not tolerated) and rucaparib will be given twice daily for 7-14 days. Each cycle will be 28 days in duration unless we need to switch to the intermediate dosing regimen of every 21 days. Both rucaparib and irinotecan will be escalated.

In dose expansion, patients who have received prior PARP inhibitors will go straight to the combination arm of irinotecan and rucaparib. If patients are PARP inhibitor naïve, they can receive single agent rucaparib until progression. Once patients on single agent rucaparib progress, they can choose to go on the combination treatment arm. Patients will continue on treatment until disease progression or intolerable toxicity.

Open to people ages 18 years and up

for Dose Escalation Cohort:

  1. Men and women, 18 years or older
  2. Understand and voluntarily sign informed consent prior to any study-related assessments or procedures are conducted and are able adhere to the study visit schedule and other protocol requirements.
  3. Solid tumors with one or more of the following DNA repair defects:
  4. BRCA1, BRCA2, ATM, BARD1, BRIP1, CDK12, CHEK2, FANCA, NBN, PALB2, RAD51, RAD51B,RAD51C, RAD51D, RAD54L (validated from archival tumor tissue or germ line testing from any CLIA approved lab). This testing should occur prior to study consent or enrollment.
  5. Presence of at least one lesion with measurable disease as defined by RECIST 1.1 criteria for response assessment
  6. Advanced solid tumor malignancy without curative options
  7. Eastern Cooperative Oncology Group (ECOG) Performance Status of ≤ 1.
  8. Adequate organ function:
  9. Absolute neutrophil count (ANC) ≥ 1.5 X 109/L
  10. Hemoglobin (Hgb) ≥9g/dL; (last transfusion cannot be within 7 days of trial initiation)
  11. Platelets (plt) ≥ 100 x 109/L
  12. AST and ALT ≤2.5 x Upper Limit Normal (ULN), <5x in patients with known liver metastases
  13. Serum total bilirubin ≤ 1.5 x ULN
  14. Creatinine<1.5 x ULN or estimated GFR ≥ 50ml/min by Cockroft-Gault(http://www.mdcalc.com/creatinine-clearance-cockcroft-gault-equation/)
  15. The effects of rucaparib on the developing fetus are unknown. Therefore
  16. Given the results of the embryo-fetal development study, in which rucaparib was embryotoxic at all doses administered, females of childbearing potential and their male partners are advised to practice a highly effective method of contraception during treatment with rucaparib and for 1 month following the last dose for females and 4 months following the last dose for males. A woman is considered to be of childbearing potential unless one of the following applies: i. Is considered to be permanently sterile. Permanent sterilization methods include hysterectomy, bilateral salpingectomy and bilateral oophorectomy.

ii. Is postmenopausal, defined as no menses for 12 months without an alternative medical cause. A high follicle-stimulating hormone (FSH) level consistently in the postmenopausal range (30 mIU/mL or higher) may be used to confirm a postmenopausal state in women not using hormonal contraception or hormonal replacement therapy;however, in the absence of 12 months of amenorrhea, a single FSH measurement is insufficient to confirm a postmenopausal state.

  1. Highly effective contraception is considered to be a method with a < 1% per year failure rate. Recommendations for highly effective contraception while taking rucaparib include: i. Ongoing use of injectable or implantable progesterone ii.Placement of an intrauterine device or intrauterine system iii. Bilateral tubal occlusion iv. Complete (as opposed to periodic) abstinence v. Male sterilization, with appropriate post-vasectomy documentation of absence of sperm in ejaculate

Additional Inclusion Criteria for Dose Expansion Cohort

  1. Mandatory biopsy on study entry, if the lesion can be biopsied with acceptable clinical risk (as judged by the investigator)
  2. . PARPi naïve or prior exposure to PARPi therapy (varies depending on Arm 1 and Arm 2)
  3. Patients in Arm 1 (single agent rucaparib followed by combination upon progression) must be PARPi naïve. Prior irinotecan is allowed
  4. Patients in Arm 2 (combination) must have been treated with and progressed on a PARPi previously. Prior irinotecan is allowed.

You CAN'T join if...

for Dose Escalation Cohort:

  1. Any significant medical condition, laboratory abnormalities, which places the subject at unacceptable risk if he/she were to participate in the study at clinician's discretion and not otherwise stated below.
  2. Allergic reaction to single-agent rucaparib or irinotecan.
  3. Myelodysplastic features on peripheral blood smear
  4. Prior allergic reaction or known intolerance to irinotecan
  5. Known Gilbert's disease
  6. Poorly controlled or symptomatic CNS metastases or carcinomatous meningitis
  7. Note: Patients with previously treated brain metastases may participate, 2 weeks after gamma knife (or equivalent) or 4 weeks after Whole Brain Radiotherapy (WBRT), provided they are stable (without evidence of progression by imaging and have not been using steroids for at least 7 days prior to study treatment.
  8. Pregnancy and breast feeding
  9. Inability to comply with study procedures or willingness to use adequate birth control

Additional Exclusion Criteria for Dose Expansion Cohort

  1. . PARPi naïve or prior exposure to PARPi therapy
  2. Patients in Arm 1 of the Dose Expansion cohort cannot have prior exposure to PARPi therapy.
  3. Patients in Arm 2 of the Dose Expansion cohort cannot be PARPi naïve.
