A Study of the Pan-immunotherapy in Patients With Relapsed/Refractory Ovarian Cancer

July 12, 2024 updated by: Han weidong, Chinese PLA General Hospital

A Randomized, Single-blind, Placebo-controlled, Phase 2 Study to Evaluate the Safety and Efficacy of the Pan-immunotherapy in Subjects With Relapsed/Refractory Ovarian Cancer

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.

Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 70 years (Adult, Older Adult)

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of Subjects with treatment-related adverse events (AEs)
Time Frame: 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.
12 months
Object response rate (ORR)
Time Frame: 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
24 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Disease control rate (DCR)
Time Frame: 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.

Time Frame: 24 months
OS time was measured from the study entry to the date of death.
24 months
Number of participants with laboratory test abnormalities
Time Frame: 12 months
