EPOCH: Eribulin and Pembrolizumab in Ovarian/Uterine Carcinosarcoma
The EPOCH study is a research trial for people with rare cancers called ovarian or uterine carcinosarcoma, where the cancer has returned or grown. Researchers are investigating two new treatment approaches: a drug called eribulin by itself, and eribulin combined with another drug, pembrolizumab. The main goal is to see how well these treatments work within 12 weeks. Additionally, the study hopes to find out if a specific protein, HMGA2, can help predict which patients are most likely to respond to these treatments. This could help doctors choose the best treatment for each person in the future.
At a glance
What is this study about?
The EPOCH study is an important international research project for people diagnosed with a rare type of cancer called tubo-ovarian or uterine carcinosarcoma. These cancers are particularly challenging to treat, especially when they come back or get worse after initial treatments. The study is trying to find better ways to help patients in this situation.
Researchers are looking at a drug called eribulin, and another called pembrolizumab. Eribulin is thought to work by changing how the cancer cells behave in a way that might make them more vulnerable. Pembrolizumab, on the other hand, is an 'immunotherapy' drug. This means it helps your own immune system fight the cancer. The study will test eribulin on its own, and then eribulin together with pembrolizumab, to see if the combination works better than eribulin alone.
A key part of this study is also to understand *why* certain treatments work for some people and not others. The team is particularly interested in a protein called HMGA2. They want to see if having high levels of this protein in cancer cells means a person is more likely to respond well to eribulin and pembrolizumab. If this is true, it could help doctors choose the most effective treatment for each individual patient in the future, making cancer care more personalised.
Key takeaways
- Tests new treatments for rare ovarian or uterine carcinosarcoma.
- Investigates eribulin alone and with immunotherapy keytruda (pembrolizumab).
- Aims to see how well treatments work within 12 weeks.
- Explores if a protein (HMGA2) can predict treatment response.
- Requires participants to have experienced cancer recurrence or progression.
Who may be eligible?
To be considered for this study, you must be over 18 years old and have a confirmed diagnosis of tubo-ovarian or uterine carcinosarcoma. The cancer must have come back or grown after you've already had at least one, but no more than two, rounds of chemotherapy. Doctors will also need to see that at least 5% of your tumour is made up of the sarcoma type of cancer cells.
It's important that your general health is good enough to take part in a study like this. This includes having good organ function (like your kidneys and liver) and being able to manage your daily activities without too much difficulty. You'll need to undergo scans like PET, CT, or MRI to confirm the cancer's return and show there are areas that can be measured to track treatment progress.
Finally, you must be willing and able to understand and sign a consent form, and commit to attending all study appointments and following the treatment plan for the duration of the trial.
Could this study suit you?
Answer these quick questions to see if you may be eligible. This is a guide only — the research team makes the final call.
- Are you over 18 years old?
- Do you have a diagnosis of tubo-ovarian or uterine carcinosarcoma?
- Has your cancer returned or grown after 1 or 2 past chemotherapy treatments?
- Are you generally well enough to manage daily activities without major difficulty?
- Are you able to attend regular hospital appointments?
What does participation involve?
If you decide to take part in this study, you'll first have some tests to make sure you're suitable, including blood tests and scans. Once accepted, you'll receive either eribulin as a single drug, or eribulin combined with pembrolizumab. These medications are given as infusions, usually in a hospital or clinic setting.
You'll have regular appointments, including physical exams, blood tests, and scans, to monitor your health, how you're responding to treatment, and to check for any side effects. The exact number of visits and the full treatment duration will be explained by the study team, but typically, clinical trials involve consistent monitoring over several months, sometimes with follow-up appointments extending beyond active treatment. You'll be told about the total estimated time commitment if you join.

Common questions
What is carcinosarcoma?
Carcinosarcoma is a rare type of cancer that contains two different kinds of cancer cells: carcinoma (which start in surface tissues) and sarcoma (which start in connective tissues like bone or muscle). This study focuses on this cancer when it affects the ovaries or uterus.
What are eribulin and pembrolizumab?
Eribulin is a chemotherapy-like drug that aims to stop cancer cells from growing. Pembrolizumab is an immunotherapy drug that helps your body's own immune system find and fight cancer cells.
Why is this study looking at a protein called HMGA2?
Researchers want to see if the levels of HMGA2 protein in your tumour can help predict if you'll respond well to the study drugs. This could help doctors choose the best treatment for you in the future.
What does 'recurrence or progression' mean?
This means your cancer has either come back after previous treatment, or it has grown or spread since your last assessment.
Will I know which treatment I am getting?
The study team will explain whether you would receive eribulin alone or in combination with pembrolizumab, and how this decision is made within the study design.
