Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.
- Ages 18 years and older
- Women only
- No healthy volunteers
- Adult, Older adult
Who may be able to join
- Adults 18 years old or older.
- Newly diagnosed epithelial adenocarcinoma of ovarian, fallopian tube or peritoneal origin FIGO Stage III or IV disease.
- Histologic epithelial cell types: high grade serous adenocarcinoma, high grade endometrioid adenocarcinoma, undifferentiated carcinoma, clear cell adenocarcinoma, mixed epithelial carcinoma, or adenocarcinoma not otherwise specified (N.O.S.).
- Completed debulking surgery (either primary debulking surgery or interval debulking surgery at the discretion of the investigator). Debulking surgery must be optimal, R1 or R0 (defined as R1, macroscopic less than 1 cm in diameter, or R0, microscopic or no evidence of tumor). Assessment of debulking surgery will be determined at the time of the surgical procedure, not by post-surgical imaging.
- For Cohort 1, subject will undergo primary debulking surgery. Subject must receive initial dose of paclitaxel 175 mg/m^2 given intravenously and carboplatin AUC 6 IV every 3 weeks for 6 cycles. Carboplatin total dose given as 5 consecutive daily pulse doses, for subjects who experiences significant grade 3 or higher emesis. Subsequent dose modifications will be instituted per protocol. Cycle 1 of chemotherapy ± oregovomab/placebo must be anticipated to occur within 6 weeks after primary debulking surgery
- For Cohort 2, subject will undergo interval debulking surgery (IDS). Prior to IDS, subjects must have receive 3 cycles of paclitaxel and carboplatin as neoadjuvant treatment. After IDS, subjects must receive paclitaxel 175 mg/m^2 IV and carboplatin AUC 5-6 IV every 3 weeks, starting cycle 4. Cycle 4 of chemotherapy ± oregovomab/placebo must be anticipated to occur within 6 weeks after IDS.

About this study
Official title: A Multicenter Phase 3, Double-Blind, Placebo-Controlled Study Comparing Chemo-Immunotherapy (Paclitaxel-Carboplatin- Oregovomab) vs Chemotherapy (Paclitaxel-Carboplatin- Placebo) in Patients With Advanced Epithelial Ovarian, Fallopian Tube or Peritoneal Carcinoma
Study to compare the safety and efficacy of oregovomab versus placebo, administered in combination with specific cycles of a standard six-cycle chemotherapy regimen (paclitaxel and carboplatin), for the treatment of subjects with newly diagnosed advanced ovarian cancer who have undergone optimal debulking.
Read the detailed description
Phase 3 double-blind, placebo-controlled, multi-center study to compare the safety and efficacy of four administrations of oregovomab 2 mg IV versus placebo, administered in combination with specific cycles of a standard six-cycle chemotherapy regimen (paclitaxel and carboplatin), for the treatment of subjects with newly diagnosed ovarian cancer who have undergone optimal debulking surgery and are either pending initiation of chemotherapy (Cohort 1 - Primary Surgery) or resumption of another three cycles of chemotherapy, having already completed three cycles of neoadjuvant chemotherapy (Cohort 2 - NACT + Interval Surgery).
For Cohort 1 - Primary Surgery, approximately 372 subjects randomized in a 1:1 ratio (i.e., chemotherapy with oregovomab or chemotherapy with placebo). For Cohort 2 - NACT + Interval Surgery, approximately 230 subjects will be randomized in a 1:1 ratio (i.e., chemotherapy with oregovomab or chemotherapy and placebo).

What is being measured
The primary outcome is the main question the study is designed to answer.
Investigator Assessed Progression Free Survival
Date of randomization to radiographically-confirmed disease progression according to RECIST v1.1 as determined by the investigator or death
Measured: Date of randomization until date of first documented disease progression or date of death from any cause, whichever comes first, at up to approximately 6 years.
Secondary outcomes (3)
Overall Survival
Date of randomization to the date of death
Measured: Date of randomization up until date of death from any cause, up to approximately 11 years
Safety and Tolerability
Incidence of adverse events (AEs) leading to discontinuation of treatment, frequency/severity of vital signs measurements, physical examination findings, and changes in clinical laboratory parameters
Measured: Date of randomization up until date of discontinuation of treatment, date of significant physical examination changes, date of significant clinical changes, up to approximately 6 years
Change in Quality of Life
- Change from baseline in the global health status/QOL scale score of the Functional Assessment of Cancer Therapy-Ovarian (FACT-O TOI)
- Three additional questions from the NFOSI-18 in each treatment group
Measured: Changes from baseline assessment, until date of discontinuation, or up to approximately 6 years

Key exclusion criteria (30 listed)
- BRCA1 or BRCA2 germline gene mutation test result with:
- Known Somatic Homologous Recombination Deficiency (HRD) who will receive PARP inhibitor front-line maintenance therapy. Subjects with somatic HRD are eligible as long as there is no intent to administer PARP inhibitor front-line maintenance therapy.
- Subjects with mucinous adenocarcinoma, carcinosarcoma, tumors with neuroendocrine features and low-grade adenocarcinoma.
- Female subjects who are lactating and breastfeeding, or have a positive serum pregnancy test within 7 days prior to the first dose of study treatment (C1D1 for Cohort 1 or C4D1 for Cohort 2).
- Any serious medical or psychiatric illness that could, in the investigator's opinion, potentially interfere with the completion of treatment according to this protocol.
Eligibility is decided by the study team after screening; this overview does not establish that a patient qualifies. Full inclusion and exclusion criteria.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Oregovomab, Paclitaxel and Carboplatin in people with Carcinoma, Ovarian Epithelial and Ovarian Neoplasms, run by CanariaBio Inc. at 148 sites in 14 countries.
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 21 inclusion and 30 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: under way, not looking for participants, as of the sponsor's last update on 1 Apr 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 148 sites in United States, South Korea, India, Argentina, Brazil and 9 more countries. 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. Some participants in this study may receive a placebo. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
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?
Investigator Assessed Progression Free Survival (time frame: Date of randomization until date of first documented disease progression or date of death from any cause, whichever comes first, at up to approximately 6 years.). 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 Apr 2026.
