Study summary

Primary stage III-IV epithelial ovarian cancer randomizing between interval cytoreductive surgery with or without hyperthermic intraperitoneal chemotherapy (HIPEC)

Read the detailed description

The goal of this phase III randomized controlled trial is to compare the clinical efficacy of HIPEC with cisplatin (trial arm) compared to no HIPEC (control arm) during interval cytoreductive surgery followed by neoadjuvant chemotherapy, in patients with stage III-IV primary epithelial ovarian cancer.

Terms in these criteria, in plain language(11)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Histologically or cytologically confirmed

The diagnosis was confirmed by looking at a sample under a microscope: tissue from a biopsy or surgery (histology), or cells from a fluid or needle sample (cytology).

Your pathology report is the document that shows this.

Adjuvant and neoadjuvant

Neoadjuvant treatment is given before the main treatment (usually surgery), often to shrink a tumour. Adjuvant treatment is given after it, to lower the chance of the cancer coming back.

Life expectancy

The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Metastases

Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.

Brain metastases

Cancer deposits in the brain from a cancer that started elsewhere in the body (CNS metastases include the spinal cord).

Studies differ: some leave out any brain metastases, some accept ones treated and stable for some weeks. Check what this study allows.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

What researchers measure

Primary outcomes

  1. Overall survival (OS)

    Time frame: From randomization to the date of death from any cause, assessed up to 5 years

Secondary outcomes

  1. Progression-free survival (PFS)

    Time frame: From randomization to time of first progression or death from any cause, whichever came first, assessed up to 5 years

  2. Cancer-specific survival

    Time frame: From randomization to the date of death due to ovarian cancer, assessed up to 5 years

  3. Time to first subsequent therapy (TFST)

    the interval from the last day of the last cycle of a prior regimen of chemotherapy to the first day of the first cycle of the subsequent regimen for each course of chemotherapy

    Time frame: from the last day of the last cycle of a prior regimen of chemotherapy to the first day of the first cycle of the subsequent chemotherapy, assessed up to 5 years

  4. Treatment-related adverse events

    assessed by CTCAE ver.5.0

    Time frame: From randomization up to the end of treatment plus 4 weeks

  5. Health-related quality of life (EORTC-QLQ-C30)

    The EORTC QLQ-C30 is a questionnaire to assess the overall quality of life of cancer patients. Participant responses to the questions are scored on a 7-point scale (1= Very poor to 7=Excellent). Using linear transformation, raw scores are standardized, so that scores range from 0 to 100. A higher score indicates a better overall health status.

    Time frame: Over the 5 year surveillance period

  6. Health-related quality of life (EORTC-QLQ-OV28)

    The EORTC QLQ-OV28 is a specified questionnaire for patients with ovarian cancer. Participant responses to the question are scored on a 4-point scale (1=Not at All to 4=Very Much). Using linear transformation, raw scores are standardized so that scores range from 0 to 100. A lower score indicates a better outcome.

    Time frame: Over the 5 year surveillance period

  7. Health-related quality of life (EQ-5D-5L)

    Each dimension in the EQ-5D-5L has five response levels: no problems (Level 1); slight; moderate; severe; and extreme problems (Level 5).

    Time frame: Over the 5 year surveillance period

  8. Cost-effectiveness analysis

    assessed by Quality-Adjusted Live Years (QALYs), incremental cost-effectiveness ratio (ICER)

    Time frame: At time of completion of 5-year surveillance period

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 May 2023 (actual). Primary completion is estimated for Dec 2027, 55 months after the start.

Of 52 non-industry phase 3 interventional studies under Ovarian Neoplasms, half reached primary completion within 81 months of starting (the median), counting those still running; a quarter within 48 and three quarters within 115. This study's planned 55 months is below that.

Counting every sponsor, half of 125 studies reached it within 59 months; a quarter within 37 and three quarters within 89.

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 Feb 13, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
