Study summary

This Phase II will evaluate a new type of ovarian cancer immunotherapy based on a fundamentally new approach that has been successfully tested in a published clinical study of liver cancer. We will test new tableted preparation, V3-OVA, obtained from hydrolyzed, inactivated blood and tumors of patients with cancer of ovaries. Study will last 3 months, 20 patients will be recruited, given one pill per day for three months. The primary clinical endpoint is effect on tumor size and burden after 3 months. Secondary endpoint will be effect on levels of tumor markers on monthly basis compared to baseline.

Read the detailed description

Ovarian cancer (OC) - a malignant disease affecting the ovarian tissue - is the sixth most diagnosed cancer among women and causes more deaths than any other cancer of the female reproductive system. For treatment of OC, surgical intervention, chemotherapy, as well as radiation methods are used. Despite treatment, about 70% of patients have a relapse. Many different types of immunotherapy (especially checkpoint inhibitors) of OC being tested, but so far the successes have been insignificant, and serious side effects are frequent and unpredictable. This Phase II will evaluate a new type of ovarian cancer immunotherapy based on a fundamentally new approach that has been successfully tested in a published clinical study of liver cancer. We will test new tableted preparation, V3-OVA, obtained from hydrolyzed, inactivated blood and tumor tissues of patients with cancer of ovaries. Study will last 3 months, 20 patients will be recruited, given one pill per day for three months. The primary clinical endpoint is effect on tumor size and burden after 3 months. Secondary endpoint will be effect on levels of tumor markers on monthly basis compared to baseline.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Jul 2018 (actual). Primary completion is estimated for Nov 2019, 16 months after the start.

Of 116 industry-sponsored phase 2 interventional studies under Ovarian Neoplasms, half reached primary completion within 37 months of starting (the median), counting those still running; a quarter within 23 and three quarters within 51. This study's planned 16 months is below that.

Counting every sponsor, half of 344 studies reached it within 47 months; a quarter within 33 and three quarters within 72.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 30, 2019, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
