Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This study is an open-label, single arm, phase 1b/II, multicenter study.

In phase 1b part, the recommended phase 2 dose of oregovomab combined with bevacizumab, paclitaxel and carboplatin will be examined. Approximately 3 to 12 subjects("3+3" dose finding design) will be enrolled in phase 1b trial with starting dose of 2mg oregovmab.

In Phase II trial, response rate of combination with oregovomab and bevacizumab, paclitaxel will be examined. Based on Simon's two stage model, 8 patients will be enrolled in first stage, after review of efficacy (response rate) of study treatment, 30 additional subjects for second stage of phase 2 will be enrolled. Considering 10% of screening failure rate, overall 42 patients will be enrolled in phase 2 trial.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

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.

Progression Free Survival (PFS)
Time Frame: Date of randomization up until date of first documented disease progression or date of death from any cause, whichever comes first
PFS, defined as date of first study treatment to the date of event defined as the first documented progression as per RECIST v1.1 or death due to any cause
