Pamiparib in Fusion Positive, Reversion Negative High Grade Serous Ovarian Cancer or Carcinosarcoma With BRCA1/2 Gene Mutations If Progression on Substrate Poly ADP Ribose Polymerase Inhibitbor (PARPI) or Chemotherapy (PRECISE)

Study Description
Brief Summary:

This study is a phase II, multi-centre, open label study in patients with advanced ovarian cancer. The treatment being tested is Pamiparib, with daily dosing.

All patients enrolled to the study will receive treatment with pamiparib. Patients will be selected for entry into the study based on the molecular signature of their cancer.


Condition or disease Intervention/treatment Phase
Ovarian Cancer Carcinosarcoma Drug: Pamiparib Phase 2

Detailed Description:

Ovarian cancer is the deadliest gynaecologic cancer in Western women. Although initially responsive to therapy, drug resistance commonly evolves.

Novel mechanisms of drug resistance in ovarian cancer have been identified and include genetic mutations that result in the activation of a drug efflux pump and secondary mutations in BRCA1/2 genes that restore the cancer cell's ability to repair treatment related DNA damage. It is hypothesized that patients with BRCA1/2 mutant high grade serous ovarian cancer or carcinosarcoma who have progressed on recent therapy and have an activated efflux pump without a secondary BRCA1/1 mutation will be selectively sensitive to a new PARPi, Pamiparib, which does not get effluxed out of cancer cells.

The primary objective of this trial is to assess the clinical benefit rate at > 4 months in 2 cohorts of patients (cohort 1: post substrate-PARP inhibitor and cohort 2: post chemotherapy) defined as response or absence of progression. Secondary objectives are to determine the median progression free and overall survival of patients treated with Pamiparib and the impact on symptom burden and benefit.

    defined as best response from commencement of treatment determined by GCIG CA-125 criteria

  7. Patient reported symptom burden [ Time Frame: At the time of consent to screening, at every cycle to 16 weeks, then every 4 cycles, and again at the time of progression. Assessed for up to 3 years after the last patient enrolled has commenced treatment. ]

    Using the Measure of Ovarian Cancer Symptoms and Treatment Concerns (MOST) v2 patient reported outcome measure (PROM)

    • The scale measures disease or therapy related symptoms and symptom burden and well-being
    • Scale ranges: Subscales are reported in five different categories with the subscale score ranges below

      • Abdominal symptoms, higher values reflecting worst possible symptoms
      • Disease or treatment-related symptoms, higher values reflecting worst possible symptoms
      • Chemotherapy-related symptoms, higher values reflecting worst possible symptoms
      • Psychological symptoms, higher values reflecting worst possible symptoms
      • Well-being, higher values reflecting best possible symptoms
    • Each of the 5 subscales can be scored and analysed separately (item by item) or by taking the average of the component items.

  8. Patient reported results of the 40 item State-trait anxiety inventory for adults (STAI-ADTM) [ Time Frame: This will be assessed 3 times - at the time of pre-screening consent, immediately prior to clinician consult with notification of pre-screening results, and immediately following notification of pre-screening results. ]
    • The scale measures state level anxiety (S-Anxiety or current levels) and trait anxiety levels (T-anxiety or how someone generally feels)
    • Scale ranges: STA Form Y-1 includes 20 items/questions, with a total score range of 20-80, and STA Form Y-2 includes 20 items/questions, with a total score range of 20-80. Each scored item/question is then given a weighted score of 1 to 4 with a rating of 4 indicative of a high level of anxiety for 10 x S-Anxiety items and 11 x T-Anxiety items. A high rating indicates the absences of anxiety for the remaining 10 S-Anxiety items and 9 T-Anxiety items. The scoring weights for the anxiety-present items are the same as the chosen numbers on the form and the scoring weight for the anxiety-absent items are reversed.
    • For each form separately, weighted scores are then totalled and averaged. Groups of respondents will be identified (including most anxious, least anxious, and middle) based on top, bottom, and middle percentiles.

  9. The type, grade and relationship to treatment of adverse events [ Time Frame: During the treatment period, on average 3 years ]
    The type, grade and relationship to treatment of adverse events, assessed according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) v5.0

Brief Summary

This study is a phase II, multi-centre, open label study in patients with advanced ovarian cancer. The treatment being tested is Pamiparib, with daily dosing.

All patients enrolled to the study will receive treatment with pamiparib. Patients will be selected for entry into the study based on the molecular signature of their cancer.

Ovarian cancer is the deadliest gynaecologic cancer in Western women. Although initially responsive to therapy, drug resistance commonly evolves.

Novel mechanisms of drug resistance in ovarian cancer have been identified and include genetic mutations that result in the activation of a drug efflux pump and secondary mutations in BRCA1/2 genes that restore the cancer cell's ability to repair treatment related DNA damage.

  6. Prior radiation therapy to target lesions in the absence of documented progression at the treated target lesion
  7. Patient has uncontrolled pleural effusion, pericardial effusion, or ascites requiring weekly recurrent drainage procedures
  8. Known history of intolerance to the excipients of the pamiparib capsule
  9. Active bleeding disorder, including gastrointestinal bleeding, as evidenced by hematemesis, significant hemoptysis, or melena ≤6 months prior to registration to pre-screening
  10. Previous complete gastric resection, chronic diarrhea, active inflammatory gastrointestinal disease, or any other disease-causing malabsorption syndrome

  2. Patient continues to meet all pre-screening inclusion criteria
  3. Patient has an ABCB1 fusion(s) and the absence of a BRCA1/2 reversion
  4. Patient has platinum sensitive or platinum resistant HGSC

    • Patients who are refractory (progress during or within 4 weeks) to second or subsequent lines of platinum-based chemotherapy are eligible
