A Study of the Pan-immunotherapy in Patients With Relapsed/Refractory Ovarian Cancer
- Conditions
- Ovarian Cancer
- Interventions
- Registration Number
- NCT03989336
- Lead Sponsor
- Chinese PLA General Hospital
- Brief Summary
Ovarian cancer is the most lethal gynecological cancer and the 5th leading cause of cancer death in women. Platinum chemotherapy has been widely adopted as a standard treatment for advanced ovarian cancer, the response rates in patients with relapsed/refractory ovarian cancer is unacceptably low. PD-1 blockade has been developed to a new class of cancer immunotherapy that could restore an adequate immunosurveillance against the neoplasm and enhance T-cell-mediated anticancer immune responses. Manganese has been confirmed to activate antigen-presenting cells and function as mucosal immunoadjuvants in pre-clinical studies. This two-arm, phase I/II study is designed to assess the safety and efficacy of combined therapy of anti-PD-1 antibody and chemotherapy with or without Manganese priming.

Group Intervention Description Manganese primed Sintilimab plus nPP chemotherapy Manganese Chloride Subject received Manganese primed Sintilimab, nab-paclitaxel and platinum chemotherapy every 3 weeks until achieving a second assessable complete response or progressive disease, development of unacceptable toxicity, or withdrawal of consent. Manganese primed Sintilimab plus nPP chemotherapy nab-paclitaxel Subject received Manganese primed Sintilimab, nab-paclitaxel and platinum chemotherapy every 3 weeks until achieving a second assessable complete response or progressive disease, development of unacceptable toxicity, or withdrawal of consent. Manganese primed Sintilimab plus nPP chemotherapy Platinum chemotherapy Subject received Manganese primed Sintilimab, nab-paclitaxel and platinum chemotherapy every 3 weeks until achieving a second assessable complete response or progressive disease, development of unacceptable toxicity, or withdrawal of consent. Sintilimab plus nPP chemotherapy nab-paclitaxel Subject received Sintilimab, nab-paclitaxel and platinum chemotherapy every 3 weeks until achieving a second assessable complete response or progressive disease, development of unacceptable toxicity, or withdrawal of consent. Sintilimab plus nPP chemotherapy Platinum chemotherapy Subject received Sintilimab, nab-paclitaxel and platinum chemotherapy every 3 weeks until achieving a second assessable complete response or progressive disease, development of unacceptable toxicity, or withdrawal of consent. Manganese primed Sintilimab plus nPP chemotherapy Sintilimab Subject received Manganese primed Sintilimab, nab-paclitaxel and platinum chemotherapy every 3 weeks until achieving a second assessable complete response or progressive disease, development of unacceptable toxicity, or withdrawal of consent. Sintilimab plus nPP chemotherapy Sintilimab Subject received Sintilimab, nab-paclitaxel and platinum chemotherapy every 3 weeks until achieving a second assessable complete response or progressive disease, development of unacceptable toxicity, or withdrawal of consent.
- Primary Outcome Measures
Name Time Method Object response rate (ORR) 24 months ORR is defined as the proportion of subjects who achieved a partial response (PR) or complete response (CR) according to Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1
Number of Subjects with treatment-related adverse events (AEs) 12 months Incidence, nature, and severity of adverse events graded according to the NCI CTCAE v5.0. AEs were considered to be treatment-related if they had started or worsened within the interval from first study drug administration until the follow-up visit.
- Secondary Outcome Measures
Name Time Method Disease control rate (DCR) 12 months DCR is defined as the proportion of subjects who achieved a stable disease (SD), partial response (PR) or complete response (CR) according to Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1.
Progression-free survival (PFS) 12 months PFS time was measured from study entry to the first documentation of disease progression or death. Disease progression was determined per the RECIST V1.1.
Overall survival (OS) 24 months OS time was measured from the study entry to the date of death.
Number of participants with laboratory test abnormalities 12 months The laboratory tests of serum cytokines and chemokines will be performed on day 1 and 3 of each cycle, and the abnormality will be determined by the investigator.
