Brief Summary:

The purpose of this study is to determine the safety and efficacy of an investigational therapeutic agent (Cvac) in ovarian cancer patients in first or second remission and to determine its ability to prevent cancer from returning.

Study objectives

Primary objectives:

  • To confirm the safety of administering Cvac in this population.
  • To determine the effects of Cvac on progression-free survival (PFS).

Secondary objectives:

  • To determine overall survival (OS) for ovarian cancer patients who receive Cvac after achieving remission in the first or second-line setting.
  • Evaluation of host immunologic response to Cvac administration.

Condition or disease Intervention/treatment Phase
Epithelial Ovarian Cancer Biological: Cvac Phase 2

Detailed Description:
An initial cohort of 7 patients were treated with Cvac in an open-label phase to confirm the safety and consistency of manufacturing between Cvac drug product manufactured in the United States (US) and Australia. After the manufacturing characteristics of Cvac were confirmed to be consistent and each patient in the initial cohort had completed 1 injection cycle of Cvac with no serious or treatment-related Grade 3 or 4 adverse events (AEs), 56 patients were enrolled and randomized (1:1) to either Cvac or observational standard of care (OSC).

Arm Intervention/treatment
Experimental: Non-randomized Cvac
Participants received 6-8 intradermal injections of Cvac at 4 sites along both upper arms and both thighs. The 6-8 injections contained ~ 60 × 10^6 dendritic cells. Following evaluation after the first dose, participants received additional injections as described for the randomized Cvac group below.
Biological: Cvac
Cvac consists of autologous dendritic cells (DCs) incubated with the antigen, mannosylated fusion protein (M-FP), to target the DCs to the specific mucin 1 antigen.

Experimental: Randomized Cvac
Participants received 6-8 intradermal injections of Cvac at 4 sites along both upper arms and both thighs every 4 weeks for 24 weeks (7 doses at Weeks 8, 12, 16, 20, 24, 28, and 32), and then every 8 weeks for 24 weeks (3 doses at Weeks 40, 48, and 56). The 6-8 injections contained ~ 60 × 10^6 dendritic cells.
Biological: Cvac
Cvac consists of autologous dendritic cells (DCs) incubated with the antigen, mannosylated fusion protein (M-FP), to target the DCs to the specific mucin 1 antigen.

No Intervention: Observational standard of care
Participants in this group did not receive any treatment during the study.

Primary Outcome Measures :
  1. Progression-free Survival [ Time Frame: Baseline to 48 weeks after the last visit or dose of Cvac (up to 104 weeks) ]
    Progression-free survival was defined as the time from randomization to the date of documented disease progression or death from any cause, whichever occurred earlier. Disease progression occurred when a patient met either the Gynecologic Cancer Intergroup (GCIG) cancer-antigen (CA)-125 definition or the Response Evaluation Criteria in Solid Tumors (RECIST) radiological definition of progressive disease. The GCIG CA-125 definition of disease progression was defined as a CA-125 level ≥ 2 × the upper limit of normal documented on 2 occasions at least 1 week apart. The radiological RECIST criteria of disease progression was defined as the appearance of new lesions or an overall increase ≥ 20% or at least 5 mm in existing tumors.

Secondary Outcome Measures :
  1. Overall Survival [ Time Frame: Baseline to the end of the study (up to 4 years 10 months) ]
    Overall survival was defined as the time from randomization until death from any cause.

  2. Change From Baseline in Mucin 1 Antibody Levels at Weeks 20, 56, and 104 [ Time Frame: Baseline to Week 104 ]
    Mucin 1 antibodies were assessed in serum samples using a quantitative enzyme-linked immunosorbent assay (ELISA). Detection was achieved with electrochemiluminescence.

  3. Change From Baseline in ICS of IL2, IL4, IL17, TNF, and IFNg in CD4+ and CD8+ Cells at Weeks 20, 56, and 104 [ Time Frame: Baseline to Week 104 ]
    Intracellular cytokine staining (ICS) for IL2, IL4, IL17, tumor necrosis factor (TNF), and interferon gamma (IFNg) was done in both CD4+ and CD8+ cells from serum samples collected at Weeks, 20, 56, and 104. Intracellular cytokine staining data were acquired with 8-color flow cytometry on a BD LSR II flow cytometer and a high-throughput screening microplate reader.

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   Female
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Female subjects ≥ 18 years old with histologically confirmed Stage III or IV epithelial ovarian, primary peritoneal or fallopian tube cancer who have previously undergone surgical cytoreduction and received first or second line conventional chemotherapy and are currently in complete remission (based on clinical and radiologic studies).
  • Cancer antigen (CA)-125 ≤ upper limit of normal with a prior history of an elevated CA-125.
  • Able and willing to undergo mononuclear cell collection.
  • Not more than 12 weeks between enrollment and the last dose of chemotherapy that resulted in complete remission.
