NEOadjuvant Dendritic Cell Vaccination for Ovarian Cancer
Induction of Neo-Antigen Specific Cytotoxic T Cells by Autologous Tumor Lysate-loaded Specialized Cross-Presenting Dendritic Cells in Epithelial Ovarian Cancer Patients Treated With Neoadjuvant Chemotherapy, the NEODOC Study
Source: ClinicalTrials.gov · Last updated 18 Nov 2025
Brief summary (registry, in English)
This goal of this single arm, single center, exploratory phase I/II clinical trial is to learn more about the immunological efficacy, safety and feasibility of an autologous tumor lysate-loaded autologous XP-DC (cDC1)-based vaccine in patients with ovarian cancer.

Who cannot take part
Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.
Prior treatment
- Unable and/or unwilling to undergo standard chemotherapy and interval debulking surgery
- Chronic treatment with systemic immunosuppressive drugs (i.e. more than 10 mg prednisolone equivalent)
Other illness
- Recurrent ovarian cancer
- Histologies other than high grade serous ovarian cancer such as, but not restricted to, endometrioid, mucinous, clear cell or carcinosarcoma
- Any serious clinical condition that may interfere with the safe administration of DC vaccinations
- Heart failure (NYHA class III/IV)
- Any uncontrolled co-morbidity, e.g. psychiatric or social conditions interfering which participation
- Active infection of Hepatitis B, C, HIV and syphilis
- Serious other active infections
- Known allergy to shell fish
- Auto immune disease (exception: vitiligo is permitted)
- History of organ allografts
Age
- History of any second malignancy, with the exception of adequately treated basal cell carcinoma, cervical cancer \> 5 years ago or early stage breast cancer \>10 years ago.
Other
- FIGO stage I-IIb, IIIa or IVb with liver, spleen or lung metastases or lymph nodes above the diaphragm or in the groins \> 1 cm
- Unable to undergo a tumor biopsy
- Pregnancy or insufficient anti-conception if reproduction is still possible
Who the study is looking for
- Women over 18 years old with histologically confirmed primary epithelial ovarian cancer.
- Not amenable by primary debulking surgery and in need of neoadjuvant chemotherapy and interval debulking
- High-grade or low grade serous histology
- FIGO stage IIIb, IIIc, IVa or IVb if only lymph nodes ≤ 1cm above the diaphragm or in the groins
- Extensive abdominal spread of tumor
- WHO/ECOG performance status 0-1
- Neutrophils \>1.5x 109/L, platelets \>100x 109/L, hemoglobin \>5,6 mmol/L (9.0 g/dl), estimated glomerular filtration rate \> 45 ml/min/1.73m2 , AST/ALT \<3 x ULN, serum bilirubin \<1.5 x ULN (exception: Gilbert's syndrome is permitted)
- Expected adequacy of follow-up
- Postmenopausal or evidence of non-childbearing status or for women of childbearing potential: negative urine or serum pregnancy test, within 28 days of study treatment and confirmed prior to treatment on day 1. Postmenopausal is defined as:
- Amenorrhoeic for 1 year or more following cessation of exogenous hormonal treatments;
- or surgical sterilisation (bilateral oophorectomy or hysterectomy).
- Informed consent
