  Purpose

The purpose of this study is to determine if an investigational cell therapy called Cvac can help EOC from returning when administered to patients who are in complete remission after surgical removal of their tumor followed by standard first-line or second-line chemotherapy.

Following surgery and study randomization, patients will undergo leukapheresis for manufacture of the study agent. After completion of chemotherapy and confirmation of complete remission, patients will enter the treatment phase of the study.

Primary Outcome Measures:
  • Overall survival (OS) [ Time Frame: Participants will be followed from randomization until the date of death from any cause or end of study, whichever comes first, assesessed up to 156 weeks. ] [ Designated as safety issue: No ]
    Assess Cvac as compared to placebo or Standard of Care (SOC) for overall survival


Secondary Outcome Measures:
  • Progression-free survival (PFS) for maintenance treatment of patients with EOC in complete remission following first-line chemotherapy or second-line treatment [ Time Frame: From date of randomization until the date of first documented progression, date of death from any cause, or end of study, whichever comes first, assessed up to 156 weeks ] [ Designated as safety issue: No ]
    PFS is defined as the time from randomization to the date of radiological scan used to determine PD, evaluated every 12 weeks after baseline.

  • Assessment of safety and tolerability of Cvac as compared to placebo or SOC [ Time Frame: 10 - 12 months ] [ Designated as safety issue: Yes ]
    Evaluated by AEs, laboratory test results, ECGs, physical examinations, and vital signs

  • Assessment of health-related quality of life questionnaires(QoL) [ Time Frame: From baseline and throughout PFS up to 156 weeks ] [ Designated as safety issue: No ]
    Quality-of-life data will be derived from the quality of life questionnaires according to the corresponding scoring manuals and will be summarized for each treatment group. Patients' health states will be derived from the EQ-5D-3L questionnaire. Data will be summarized by treatment group and analyzed using descriptive statistics.

Detailed Description:

This study proposes a nontoxic immunotherapeutic approach to extend the overall survival in patients in complete remission.

Most patients with ovarian cancer achieve complete clinical remission after optimal debulking surgery and first-line platinum-based chemotherapy. However, most patients, despite high response rates to first-line treatment, will relapse and undergo subsequent lines of chemotherapy. Generally, the progression-free interval between treatments becomes shorter with each relapse, and the patient eventually dies of the disease.
