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
Has provided documented informed consent for the study.
Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.
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 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.
Single group
Weekly Paclitaxel/Nab-Paclitaxel, Pembrolizumab, and Mirabegron
DrugParticipants 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.
Objective response rate (ORR)
Objective Response Rate (ORR) Per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) by Blinded Independent Central Review (BICR). ORR was defined as the percentage of participants who had a Complete Response (Disappearance of all target lesions) or a Partial Response (≥30% decrease in the sum of the longest diameter of target lesions) using RECIST 1.1 based on BICR.
Progression Free Survival (PFS) at 6 Months
PFS was defined as the time from first dose of study treatment to the first documented progressive disease (PD) per RECIST 1.1 based on BICR, or death due to any cause, whichever occurred first. Per RECIST 1.1 PD was defined as ≥20% increase in SOD of target lesions and an absolute SOD increase of ≥5 mm. The appearance of ≥1 new lesion is also PD. PFS at 6 months is defined as the percentage of patient who was progression free at 6 months from the date of first study treatment.
Overall Survival (OS) at 6 Months
OS at 6 months is defined as the percentage of patients who are alive at 6 months from the date of first study treatment.
Progression Free Survival (PFS) at 12 Months
PFS was defined as the time from first dose of study treatment to the first documented progressive disease (PD) per RECIST 1.1 based on BICR, or death due to any cause, whichever occurred first. Per RECIST 1.1 PD was defined as ≥20% increase in SOD of target lesions and an absolute SOD increase of ≥5 mm. The appearance of ≥1 new lesion is also PD. PFS at 12 months is defined as the percentage of patient who was progression free at 12 months from the date of first study treatment.
Overall Survival (OS) at 12 Months
OS at 12 months is defined as the percentage of patients who are alive at 12 months from the date of first study treatment.
