- Adult, Older adult
Who may be able to join
- Primary HGSOC patients (FIGO stage 3B to IV) who completed primary treatment defined as:
- primary debulking surgery (complete / optimal) and 6 cycles of adjuvant chemotherapy (carboplatin/paclitaxel)
- 3 cycles of neo-adjuvant chemotherapy (more NACT cycles to improve surgical outcome are allowed) followed by interval debulking surgery (complete / optimal) and 3 cycles of adjuvant chemotherapy (carboplatin/paclitaxel)

- Patients must have no uncontrolled infection with human immunodeficiency virus, hepatitis B or hepatitis C infection; or diagnosis of immunodeficiency that is related to, or results in chronic infection. Mild cancer-related immunodeficiency (such as immunodeficiency treated with gamma globulin and without chronic or recurrent infection) is allowed.

Patients with controlled infections must undergo periodic monitoring of HBV DNA per local standards. Patients must remain on anti-viral therapy for at least 6 months beyond the last dose of trial treatment.

About this study
Official title: An Open Label, Phase 1 Study to Evaluate the Safety, Feasibility and Immunogenicity of an Allogeneic, Cell-based Vaccine (DCP-001) in High Grade Serous Ovarian Cancer Patients After Primary Treatment
Phase I study to evaluate safety and systemic immunogenicity of the DCP-001 vaccine in patients with high grade serous ovarian cancer after primary treatment.
Read the detailed description
This is a first phase I study in HGSOC patients with primary disease eligible for standard of care treatment with either; complete or optimal primary cytoreductive surgery followed by 6 cycles of adjuvant chemotherapy (carboplatin/paclitaxel); or 3 cycles of neoadjuvant chemotherapy (carboplatin/paclitaxel) followed by complete or optimal cytoreductive interval surgery and 3 additional cycles carboplatin/paclitaxel.
In the current study, DCP-001 vaccinations will be scheduled after standard of care treatment, starting 6 weeks after the last cycle of chemotherapy.
Patients will receive 4 vaccinations containing 25E6 DCP-001 cells per vaccination followed by 2 additional booster vaccinations of 10E6 cells. Each patient will be followed up for 24 months. Safety will be monitored throughout the study. Systemic immune responses are determined by standard immune assays using peripheral blood mononuclear cells (PBMCs) and serum collected before, during and after vaccinations. Progression of disease will be monitored according to standard-of-care follow-up.

DCP-001Biological
allogeneic dendritic cell vaccine
| Study group | Role | What they receive |
|---|---|---|
| Treatment arm | Experimental | Patients receiving 4 bi-weekly vaccinations with 25E6 cells/vaccination of DCP-001, and 2 booster vaccinations with 10E6 cells/vaccination Receives: Biological: DCP-001 |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change from baseline DCP_001 vaccine antigen-specific T cells in the peripheral blood (systemic induction / expansion of DCP_001 vaccine antigen-specific T cells)
Systemic DCP-001 vaccine specific response is measured by the number of patients with de novo or increased immune responses based on IFNƴ ELISpot assay in any or more of the post-vaccination PBMC samples to at least one of the following DCP-001 vaccine antigens compared to baseline: WT-1, Survivin, RHAMM or PRAME, specific cancer testis antigens as NY-ESO1 and MAGE3.
Measured: A PBMC collection is planned at baseline, before start treatment. Further PBMC collections are scheduled during (4 times) and after the vaccinations.
Secondary outcomes (3)
Safety and tolerability of the repetitive doses of the DCP-001 vaccine
Number of patients with AEs, and SAEs
Measured: Up to 28 days after last vaccination
Recurrence free survival (RFS)
RFS defined as the number of patients alive without any progress or recurrence (local or regional, or distant) and death due to any cause
Measured: Up to 2 years from disease diagnosis
Overall survival (OS)
OS defined as the number of patients alive, measured in months, up to 2 years from disease diagnosis.
Measured: Up to 2 years from disease diagnosis

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing DCP-001 in people with Ovarian Cancer, run by University Medical Center Groningen at 1 site in Netherlands.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 6 inclusion and 13 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 1 May 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Netherlands. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change from baseline DCP_001 vaccine antigen-specific T cells in the peripheral blood (systemic induction / expansion of DCP_001 vaccine antigen-specific T cells) (time frame: A PBMC collection is planned at baseline, before start treatment. Further PBMC collections are scheduled during (4 times) and after the vaccinations.). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 May 2026.
