Study summary

In BriTROC-2, up to 250 women with a confirmed diagnosis of high-grade serous/high-grade endometrioid or carcinosarcoma will be eligible for full consent (Part 2) and registration to BriTROC-2 and will be followed prospectively until first relapse. Women with presumed newly-diagnosed high-grade serous carcinoma of the ovary, fallopian tube or peritoneum can be approached for consent to Part 1 (screening consent) of BriTROC-2 prior to formal diagnosis.

The aim of this study is to acquire tumour material at diagnosis and relapse, whole blood for genomic analysis and plasma for ctDNA. This study will also isolate single cells and establish organoid cultures from ascites/peritoneal washings.

Read the detailed description

BriTROC-2 is a sample collection study from women with ovarian cancer from the point of diagnosis to the time of disease relapse.

Ovarian cancer has a poor prognosis. The large majority of patients with ovarian cancer will relapse and ultimately develop fatal chemotherapy resistance. Although there is a wealth of information regarding the molecular basis of ovarian cancer at diagnosis, very little is known about the drivers of treatment resistance (both intrinsic and acquired) and the processes that are active at relapse. This research requires sequential collection of tumour material for women throughout the course of their disease.

This multicentre study will collect tumour samples, ascites (fluid within the abdomen) and blood from women with newly diagnosed ovarian cancer and follow these women through to relapse of their disease. The samples collected will be used to look at patterns within the tumour to identify those that are able to predict response to chemotherapy and outcome. Assays and models will be developed that can look at the process that are active in a tumour at time of sample acquisition. This will give clues into the mechanisms that drive treatment resistance. Ultimately this research aims to guide future treatment options for women with ovarian cancer.

Recruitment will be over 3 years and this study will be conducted at sites with expertise in managing ovarian cancer and the ability to carry out the appropriate sample collection and collect high quality clinical data.

This study is the second collaborative project within the UK to collect samples from women with ovarian cancer. The success of the first study, BriTROC-1, demonstrated the feasibility of sample collection from women with relapsed ovarian cancer. The methods and frameworks established in BriTROC-1 will be used for BriTROC-2.

Study population

In BriTROC-2, a cohort of women with presumed newly-diagnosed high-grade carcinoma of the ovary, fallopian tube or peritoneum will be recruited at the time of diagnosis and approached for consent to Part 1 (screening consent) of BriTROC-2. Up to 250 women with a confirmed diagnosis of high-grade serous/high-grade endometrioid or carcinosarcoma will be eligible for full consent (Part 2) and registration to BriTROC-2 and will be followed prospectively until first relapse. The aim of this study is to acquire tumour material at diagnosis and relapse, whole blood for genomic analysis and plasma for ctDNA. This study will also isolate single cells and establish organoid cultures from ascites/peritoneal washings.

Inclusion criteria

  1. Age ≥ 16 years.
  2. Ability to provide written prior to participating in the trial and any trial related procedures being performed.
  3. Ovarian, fallopian tube or primary peritoneal carcinoma of high-grade serous, high-grade (grade 3) endometrioid or carcinosarcoma histologies.
  4. Patients with ovarian, fallopian tube or primary peritoneal carcinoma of any histological subtype in patients with known germline mutations in BRCA1 or BRCA2.
  5. Willingness to comply with scheduled visits, treatment plans, laboratory tests and other trial procedures.
  6. > 6 months.
  7. No to obtaining a surgical or image-guided .
  8. Patients with confirmed ovarian, fallopian tube or primary peritoneal carcinoma of high-grade serous, high-grade (grade 3) endometrioid or carcinosarcoma histologies who have consented for their tissue to be collected under a generic tissue consent (i.e. have not consented to Part 1) may be eligible for full consent following discussion with the trials team.

Exclusion criteria

Exclusion Criteria:

  1. Ovarian, primary peritoneal or fallopian tube cancer of low grade serous, grades 1 or 2 endometrioid or clear cell subtypes unless associated with known germline mutation in BRCA1 or BRCA2
  2. Borderline/low malignant potential tumours
  3. Any non-epithelial ovarian
  4. Diagnosis of high-grade serous cancer made on cytology only
  5. Patients who have received any prior treatment for known high-grade ovarian carcinoma
  6. Other severe or uncontrolled systemic disease or evidence of any other significant disorder or lab finding that makes it undesirable for the patient to participate in the trial
  7. History of physical or psychiatric disorder that would prevent and compliance with protocol
  8. Pregnant or lactating women
  9. Patients with any other severe concurrent disease which may increase the risk associated with trial participation
  10. Any psychological, familial, sociological or geographical consideration potentially hampering compliance with the trial protocol and follow up schedule.
Terms in these criteria, in plain language(5)

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.

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.

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.

Biopsy and archival tissue

A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.

Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.

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.

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 Oct 2021 (actual). Primary completion is estimated for Oct 2024, 36 months after the start.

Of 216 non-industry observational studies under Ovarian Neoplasms, half reached primary completion within 71 months of starting (the median), counting those still running; a quarter within 35 and three quarters within 206. This study's planned 36 months is below that.

Counting every sponsor, half of 268 studies reached it within 61 months; a quarter within 35 and three quarters within 185.

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 Sep 23, 2022, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
