About

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

Enrollment: 20 estimated patients

• 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.
