Pegylated Liposomal Doxorubicin Plus Adebrelimab With or Without Mirabegron in Relapsed Ovarian Cancer

Recruiting now · Phase 2/Phase 3

Conditions studied: Ovarian Cancer Recurrent

In brief

The goal of this clinical trial is to learn if drug regimen pegylated liposomal doxorubicin and adebrelimab with or without mirabegron works to treat relapsed ovarian cancer in adults. It will also learn about the safety of drug regimen pegylated liposomal doxorubicin and adebrelimab with or without mirabegron. The main questions it aims to answer are: Does drug pegylated liposomal doxorubicin and adebrelimab with or without mirabegron reduce tumor volume? What medical problems do participants have when taking drug pegylated liposomal doxorubicin and adebrelimab with or without mirabegron? Researchers will compare drug regimen pegylated liposomal doxorubicin and adebrelimab with mirabegron to a drug regimen pegylated liposomal doxorubicin and adebrelimab without mirabegron to see which drug regimen works better to treat relapsed ovarian cancer. Participants will: Take drug pegylated liposomal doxorubicin and adebrelimab every 21 days with or without everyday mirabegron Visit the clinic once every 2 months for checkups and tests Keep a diary of their symptoms

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.

You may not qualify if…

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) or has participated in prior adebrelimab studies.
Has received prior systemic anticancer therapy including radiation therapy or maintenance therapy within 4 weeks before randomization.
Has severe hypersensitivity (≥Grade 3) or uncontrolled hypertension to pegylated liposomal doxorubicin, adebrelimab, mirabegron and any of their excipients.
Has undergone major surgery within 3 weeks before randomization 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 randomization.
Has a history of active autoimmune disease.
Has an active infection requiring systemic therapy.
