Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Description of intervention(s) / exposure
Treatment: Other - Pembrolizumab
Treatment: Drugs - Paclitaxel
Treatment: Drugs - Bevacizumab
Other interventions - Placebo for pembrolizumab
Treatment: Drugs - Docetaxel

Experimental: Pembrolizumab + paclitaxel ± bevacizumab - Participants receive pembrolizumab 400 mg via intravenous (IV) infusion for eighteen 6-week cycles (approximately 2 years) PLUS paclitaxel 80 mg/m\^2 via IV infusion on Days 1, 8, and 15 of each 3-week cycle until intolerance or disease progression. Participants who experience severe hypersensitivity reaction to paclitaxel or an AE requiring discontinuation of paclitaxel may receive docetaxel (75 mg/m\^2 every 3 weeks \[Q3W\]) after Sponsor consultation. Participants may also receive bevacizumab 10 mg/kg via IV infusion of each 2-week cycle until intolerance, disease progression, or at the Investigator's discretion.

Placebo comparator: Placebo + paclitaxel ± bevacizumab - Participants receive placebo via IV infusion for eighteen 6-week cycles (approximately 2 years) PLUS paclitaxel 80 mg/m\^2 via IV infusion on Days 1, 8, and 15 of each 3-week cycle until intolerance or disease progression. Participants who experience severe hypersensitivity reaction to paclitaxel or an AE requiring discontinuation of paclitaxel may receive docetaxel (75 mg/m\^2 every 3 weeks \[Q3W\]) after Sponsor consultation. Participants may also receive bevacizumab 10 mg/kg via IV infusion of each 2-week cycle until intolerance, disease progression, or at the Investigator's discretion.

Eligibility
Key inclusion criteria
* Has histologically confirmed epithelial ovarian, fallopian tube, or primary peritoneal carcinoma.
* Has received 1 or 2 prior lines of systemic therapy for ovarian cancer (OC), including at least 1 prior platinum-based therapy. Participants may have received a prior poly (ADP-ribose) polymerase inhibitor (PARPi), anti-PD-1/anti-PD-L1 therapy, bevacizumab, or hormonal therapy; these will not be considered a separate line of therapy. Any chemotherapy regimen change due to toxicity in the absence of disease progression will be considered part of the same line of therapy.
* Has provided documented informed consent for the study.
* Has radiographic evidence of disease progression within 6 months (180 days) after the last dose of platinum-based chemotherapy for OC (i.e., platinum-resistant disease).
* Is a candidate for paclitaxel chemotherapy (and bevacizumab, if using).
* Has an Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 1 assessed within 3 days before randomization.
* For a female participant, she is not pregnant or breastfeeding, and at least one of the following conditions applies: Is not a woman of childbearing potential (WOCBP) OR Is a WOCBP and uses a contraceptive method that is highly effective (with a failure rate of <1% per year).
* Has radiographically evaluable disease, either measurable or nonmeasurable per RECIST 1.1, as assessed by the local site investigator.
* Archival tumor tissue sample or newly obtained core or incisional/excisional biopsy of a tumor lesion not previously irradiated has been provided.
* Have adequate organ function.

Key exclusion criteria

* Has prior disease progression on weekly paclitaxel alone.
* Has received >2 prior lines of systemic therapy for OC.
* Has received prior systemic anticancer therapy including investigational agents or maintenance therapy (including bevacizumab maintenance therapy), within 4 weeks before randomization.
* Has received prior radiation therapy within 2 weeks of start of study intervention.
* Has not recovered adequately from surgery and/or any complications from the surgery.
* Has received colony-stimulating factors (e.g., granulocyte colony-stimulating factor [G-CSF], granulocyte-macrophage colony-stimulating factor,[GM-CSF] or recombinant erythropoietin) within 4 weeks before randomization.
* Has received a live or live-attenuated vaccine within 30 days before the first dose of study intervention.
* Has received investigational agent or has used an investigational device within 4 weeks prior to study intervention.

* Has a known additional malignancy that is progressing or has required active treatment within the past 3 years.
* Has known active central nervous system (CNS) metastases and/or carcinomatous meningitis.

* Has had an allogenic tissue/solid organ transplant.

For bevacizumab treatment

* Has uncontrolled hypertension.
* Has current, clinically relevant bowel obstruction including related to underlying epithelial OC, abdominal fistula or gastrointestinal perforation, intra-abdominal abscess, or evidence of rectosigmoid involvement by pelvic exam.

Summary
Brief summary
The primary objective is to compare pembrolizumab plus paclitaxel with or without bevacizumab to placebo plus paclitaxel with or without bevacizumab, with respect to progression-free survival (PFS) per Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 as assessed by the investigator. The hypotheses are that pembrolizumab plus paclitaxel with or without bevacizumab is superior to placebo plus paclitaxel with or without bevacizumab, with respect to PFS per RECIST 1.1 as assessed by the investigator for participants with programmed cell death ligand 1 (PD-L1) positive tumors (Combined Positive Score \[CPS\] =1) and that pembrolizumab plus paclitaxel with or without bevacizumab is superior to placebo plus paclitaxel with or without bevacizumab, with respect to PFS per RECIST 1.1 as assessed by the investigator for all participants.
