Study Endpoints
Primary Endpoints
Progression-free Survival
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.

ArmTypeDescription
Non-randomized CvacEXPERIMENTALParticipants 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.
Randomized CvacEXPERIMENTALParticipants 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.
Observational standard of careNO_INTERVENTIONParticipants in this group did not receive any treatment during the study.
Interventions
NameTypeDescription
CvacBIOLOGICALCvac 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.
