Clinical Trial Summary

Part 1 (Phase 1): safety and tolerability of bevacizumab-Niraparib combination Part 2 (Randomized Phase 2): to compare Progression-Free Survival (PFS)

PARP inhibitors are active as monotherapy to treat patients with recurrent ovarian cancer; the strongest activity being observed in the platinum sensitive, gBRCAmut subgroup as well as in gBRCAwt, HRD population but also in HRD negative disease.

In the same population there is level one evidence that bevacizumab is beneficial. And a phase two randomized study has indicated that combination of a PARP inhibitor with anti-angiogenic drug is superior to PARP inhibitor alone.

The question is:

Is niraparib combined with bevacizumab superior to niraparib? The comparison of tolerability and efficacy of niraparib-bevacizumab combination against niraparib.

Description:

Part 1: This is a single-centre, phase 1a, open-label, dose-escalation study to evaluate the safety and tolerability of bevacizumab-niraparib combination and determine the RP2D in patients with platinum-sensitive epithelial ovarian, fallopian tube, or primary peritoneal cancer.

The standard 3+3 design will be used. Part 2: (n=94) This multicenter, prospective, open-label, randomized phase 2 study is evaluating the efficacy of niraparib against niraparib-bevacizumab combination in Women with platinum-sensitive epithelial ovarian, fallopian tube, or primary peritoneal cancer.

Stratification: Patients are stratified according to:

1. HRD status (positive/negative)

2. Treatment-Free interval to prior therapy (6-12 months > 12 months) Randomization: 1:1 randomization

Study arms: Patients are randomized to one of the two treatment arms:

Arm 1: Niraparib monotherapy until progression. Arm 2: Niraparib-bevacizumab combination therapy until progression.

Eligibility

Inclusion Criteria:

A patient will be eligible for inclusion only if all of the following criteria are fulfilled:

1. Recurrent platinum-sensitive epithelial ovarian, fallopian tube, or peritoneal cancer (platinum sensitivity defined as no recurrence within 6 months of last receipt of platinum/chemotherapy).

2. High-grade serious or high-grade endometrioid histology.

3. Patient consents to perform HRD test.

• Patients with known BRCA status: BRCA positive patients must submit the tissue for HRD test, though these patients need not to wait for HRD test results and can be randomized in HRD positive stratum.

• If tumor tissue is not sufficient to perform HRD test: these patients shall be randomized in HRD negative stratum as HRD unknown.

4. Prior line of therapy: Patients must have received platinum-containing therapy for primary disease.

• No limits on number of platinum-based therapies. Population of patients who has previously received = 3 lines of therapy for relapsed disease will be capped at 40%.

• Up to one non-platinum-based line of therapy in recurrent setting.

• Patients who are treated with bevacizumab just prior to entering in the trial must not have progressed under or within 3 months after bevacizumab.

• Patients may have participated in a PARP inhibitor trial as first-line maintenance therapy and have not progressed within 3 months after PARP/placebo. Patients who received PARP inhibitor after relapse (definitive or maintenance therapy) are not eligible.

5. Target group: Age 18+

6. Histological confirmed ovarian, fallopian tube or peritoneal cancers

7. Patients must give informed consent

8. Patients may have undergone primary or interval debulking surgery

9. Patients may have received bevacizumab though no other prior use of anti-angiogenic therapy

10. Patients may have received a PARP inhibitor as first-line maintenance therapy.

11. Patients must have disease that is measurable according to RECIST or assessable according to the GCIG criteria

12. The patient agrees to complete PROs (QoL questionnaire) during study treatment AND at one additional time point 8 weeks following progression of disease

6. Active infections or other serious underlying significant medical illness, abnormal laboratory finding or psychiatric illness/social situation that would, in the Investigator's judgment, makes the patient inappropriate for this study
