Clinical Trial Summary

The purpose of this trial is to investigate if maintenance DCVAC/OvCa after second-line chemotherapy of carboplatin/gemcitabine or carboplatin/paclitaxel improves efficacy outcomes in women with FIGO stage III and IV epithelial ovarian carcinoma who experienced relapse more than 6 months after complete remission of first line platinum-based chemotherapy (platinum sensitive ovarian cancer)

Description:

All patients who fulfill all eligibility criteria will undergo a leukapheresis procedure. All eligible/enrolled patients will receive standard-of-care therapy with carboplatin/gemcitabine or carboplatin/paclitaxel starting 2 to 7 days after leukapheresis. After 6 cycles of chemotherapy, patients will start maintenance treatment with DCVAC/OvCa. Treatment will continue irrespective of tumor progression until completion, refusal, intolerance of treatment or death.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Progression Free Survival by modifications to the RECIST 1.1	PFS as defined as the time from the first dose of Standard-of-Care (SoC) therapy administerd until tumor progression or death from any cause	Assessed from enrollment up to 104 weeks
Secondary	Overall survival	Defined as the time from first dose of SoC therapy administered until death due to any cause assessed until study completion	Assessed from enrolment through study completion approximately 5 years
Secondary	Biological progression-free interval	Defined by increasing CA-125 levels per Gynecologic Cancer Intergroup (GCIG) criteria	CA-125 assessed every 6 weeks up to 104 weeks
Secondary	Objective Response rate	CR and PR measured by the modifed RECIST 1.1 criteria	Response is assessed every 8 weeks up to 104 weeks
Secondary	Immunologic Response	Detection of entire anti-tumor immune response int he serum	Blood samples collected 5 times throughout the study from enrolment up to 104 weeks
Secondary	Incidence of Treatment-emergent adverse events [safety and tolerability]	Safety profile as determined by the nature, incidence, duration, severity and outcome of adverse events (AEs) including serious AEs (SAEs) as assessed by CTCAE v. 4.0	Screening through 30 days after completion of treatment
Secondary	CA-125 response	Defined by GCIG criteria	CA-125 assessed every 6 weeks up to 104 weeks
Secondary	Time to either tumor or biologic Response	Response according to RECIST or CA-125 measurements as increased to >2 times ULN	From first dose of chemotherapy until either objective or serologic progression for up to 104 weeks.
