Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this clinical trial is to learn if drug regimen weekly paclitaxel/nab-paclitaxel, pembrolizumab, and mirabegron works to treat relapsed ovarian cancer in adults. It will also learn about the safety of the drug regimen. The main questions it aims to answer are:

i) Does drug weekly paclitaxel/nab-paclitaxel, pembrolizumab, and mirabegron reduce tumor volume? ii) What medical problems do participants have when taking drug weekly paclitaxel/nab-paclitaxel, pembrolizumab, and mirabegron?

Participants will:

i) Take drug paclitaxel/nab-paclitaxel every week and pembrolizumab every 21 days with everyday mirabegron ii) Visit the clinic once every 2 months for checkups and tests iii) Keep a diary of their symptoms

Blinding Strategy

NONE

This is a single-arm, open-label, Phase II interventional study designed to evaluate the efficacy and safety of weekly paclitaxel or nab-paclitaxel in combination with pembrolizumab and mirabegron in patients with recurrent ovarian cancer. All eligible participants will receive the same treatment regimen without randomization or masking. The study aims to assess treatment response, safety profile, and preliminary clinical benefit in this target population.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Weekly Paclitaxel/Nab-Paclitaxel, Pembrolizumab, and Mirabegron

Participants receive weekly paclitaxel/nab-paclitaxel plus pembrolizumab via intravenous (IV) infusion plus on Day 1 of each 21-day cycle orally with daily mirabegron until intolerance or disease progression.

Group Type EXPERIMENTAL

* Has histologically confirmed epithelial ovarian, fallopian tube, or primary peritoneal carcinoma.
* Has received a front line platinum-based regimen (administered via either intravenous or intraperitoneal route) per local standard of care or treatment guideline following the primary or interval debulking surgery with documented disease recurrence (note: Maintenance treatment following the front line treatment is permitted and counted together as part of the front line treatment).
* Has a platinum-free interval (PFI) of \< 12 months if the last regimen received is a platinum-based, or a treatment-free interval (TFI) of \< 12 months if the last regimen received is a non-platinum-based.
* Has measurable disease at baseline based on Response Evaluation Criteria in Solid Tumors (RECIST) 1.1.
* Has a life expectancy of ≥12 weeks.
* Has provided a tumor tissue sample either collected from prior cytoreductive surgery or fresh newly obtained tumor tissue at screening.
* Has adequate organ function.
* Has not recovered from AEs to ≤ Grade 1 or prior treatment level due to a previously administered agent.

Exclusion Criteria

* Has nonepithelial cancers, borderline tumors, mucinous, seromucinous that is predominantly mucinous, malignant Brenner's tumor and undifferentiated carcinoma.
* Has received prior therapy with an anti-programmed cell death (PD)-1, anti-PD-L1, anti-PD-L2 agent or with an agent directed to another co-inhibitory T-cell receptor (e.g. cytotoxic T-lymphocyte-associated antigen-4 \[CTLA-4\], tumor necrosis factor receptors OX-40 or CD137).
* Has received prior systemic anticancer therapy including radiation therapy or maintenance therapy within 4 weeks before enrollment.
* Has severe hypersensitivity (≥Grade 3) or uncontrolled hypertension to paclitaxel/nab-paclitaxel, pembrolizumab, mirabegron and any of their excipients.
* Has undergone major surgery within 3 weeks before enrollment or has complications/sequelae that have not yet recovered.
* Has a known additional malignancy that progressed or required active treatment within the last 5 years.
* Is pregnant or breastfeeding.
* Has a history of allogenic tissue/solid organ transplant.
* Has a history of thrombotic disorders, hemorrhage, hemoptysis, or active gastrointestinal bleeding within 6 months before enrollment.
* Has a history of active autoimmune disease.
* Has an active infection requiring systemic therapy.
* Has a history of human immunodeficiency virus (HIV) infection.
* Has a history of Hepatitis B or C virus infection.
* Has a history or current evidence of any condition, therapy, laboratory abnormality, or other circumstance that might confound the results of the study.
