DCVAC/OvCa and Standard of Care (SoC) in Relapsed Ovarian, Fallopian Tube, and Primary Peritoneal Carcinoma

Phase 3
Withdrawn
Conditions
Ovarian Cancer
Fallopian Tube Cancer
Peritoneal Carcinoma
Interventions
Biological: DCVAC/OvCa
Biological: DCVAC/OvCa placebo
Registration Number
NCT03905902
Lead Sponsor
SOTIO a.s.
Brief Summary

Multi-center, phase III trial of DCVAC/OvCa added to standard of care treatments for relapsed ovarian cancer. Patients will receive study treatment until all doses are administered, or other criteria are met.

Detailed Description

All patients who meet entry criteria will be randomized, and will undergo a leukapheresis procedure. During the Induction period, all patients will receive DCVAC/OvCa or placebo (study treatment) with concurrent standard-of-care platinum-based chemotherapy, with or without use of bevacizumab. In the Maintenance period, patients will continue treatment with study treatment in combination with bevacizumab, a poly (ADP-ribose) polymerase inhibitor (PARPi) or best supportive care only. Study treatment will continue irrespective of disease progression

Inclusion Criteria
  • Histologically confirmed high-grade serous or endometrioid carcinoma of the ovary, peritoneum or fallopian tube.
  • Without disease progression during preceding platinum-based chemotherapy
  • Platinum-sensitive patients defined as Platinum-Free Interval of more than 6 months between the end of the last cycle of platinum-based chemotherapy and radiologic evidence of progression.

Exclusion Criteria
  • Tumor-specific: any other histology sub-type that is not high grade serous or endometrioid, however a combination of these is allowed
  • Disease Treatment history: started or ongoing systemic treatment for current relapse of Epithelial Ovarian Cancer, Fallopian Tube Cancer or Primary Peritoneal Cancer before signing informed consent form (ICF), concomitant use of anti-neoplastic anti- hormonal therapy
