Primary stage III-IV epithelial ovarian cancer randomizing between interval cytoreductive surgery with or without hyperthermic intraperitoneal chemotherapy (HIPEC)
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.
3,381 studies on the registry are indexed under Ovarian Neoplasms; 790 are open to participants now.
This study's planned enrollment of 520 is above the median of 54 across 2,548 interventional studies indexed under Ovarian Neoplasms.

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

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
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
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
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

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.
