      Trial Summary

      This study will evaluate the efficacy and safety of multiple biomarker-selected treatments in patients with persistent or recurrent rare epithelial ovarian, fallopian tube, or primary peritoneal tumors. Enrollment will take place in two phases: a preliminary phase followed by a potential expansion phase.

      How does the BOUQUET clinical trial work?

      This clinical trial is recruiting people who have types of disease called rare epithelial ovarian, fallopian tube or primary peritoneal cancer. In order to take part, patients must have previously received treatment for their cancer.

      The purpose of this clinical trial is to test the effects, good or bad, of different treatments in patients with different genetic changes (biomarkers) in their cancer. In this clinical trial, you will get either ipatasertib plus paclitaxel, cobimetinib, trastuzumab emtansine or atezolizumab plus bevacizumab, depending on the genetic changes found in your cancer. 

      How do I take part in this clinical trial?

      To be able to take part in this clinical trial, you must be at least 18 years old and have been diagnosed with rare epithelial ovarian, fallopian tube or primary peritoneal cancer according to certain criteria. You must have previously received treatment for your disease, including at least one platinum-based treatment.

      You must not be pregnant or breastfeeding, or intending to become pregnant or breastfeed, during the clinical trial. You may also not be able to take part in this clinical trial if you have previously received certain other medications or have certain other medical conditions. For each treatment available in this clinical trial, there are also other specific exclusion criteria that your doctor will be able to discuss with you.

      If you think this clinical trial may be suitable for you and would like to take part, please talk to your doctor. If your doctor thinks that you might be able to take part in this clinical trial, he/she may refer you to the closest clinical trial doctor. They will give you all the information you need to make your decision about taking part in the clinical trial. You can also find the clinical trial locations on this page.

      You will have some further tests to make sure you will be able to take the treatments given in this clinical trial. Some of these tests or procedures may be part of your regular medical care. They may be done even if you do not take part in the clinical trial. If you have had some of the tests recently, they may not need to be done again.

      Before starting the clinical trial, you will be told about any risks and benefits of taking part in the trial. You will also be told what other treatments are available so that you may decide if you still want to take part. 

      While taking part in the clinical trial, women (if you are not currently pregnant but can become pregnant) will need to either not have heterosexual intercourse or take contraceptive medication for safety reasons. 

      What treatment will I be given if I join this clinical trial?

      Everyone who joins this clinical trial will have tests to look for different genetic changes, known as biomarkers, in their cancer (biomarker screening). The tests are performed on a small tissue sample taken from the tumour – this is known as a biopsy and your doctor can advise on how your tissue sample may be taken.

      Once enrolled on the clinical trial, patients will be assigned to one of four groups depending on the biomarkers found. This will determine which treatment they will be given:

      • Patients with changes in the PTEN, PIK3CA and/or AKT1 genes will receive ipatasertib, given as a pill once a day on Days 1–21 of a 28-day cycle, plus paclitaxel as an infusion into the vein on Days 1, 8 and 15 of a 28-day cycle. Patients may also be given other medications to reduce the risk of side effects with ipatasertib plus paclitaxel, such as an allergic reaction or diarrhoea
      • Patients with changes in the BRAF, KRAS, NRAS and/or NF1 genes will receive cobimetinib, given as a pill once a day on Days 1–21 of a 28-day cycle
      • Patients with changes in the ERBB2 gene will receive trastuzumab emtansine, given as an infusion into the vein on Day 1 of a 21-day cycle
      • Patients with none of the above changes will receive atezolizumab plus bevacizumab, each given as infusions into the vein on Day 1 of a 21-day cycle

      This is an open-label clinical trial. This means that both you and your clinical trial doctor will know which treatment you are being given. 

      How often will I be seen in follow-up appointments and for how long?

      You will be given the clinical trial treatment ipatasertib plus paclitaxel, cobimetinib, trastuzumab emtansine or atezolizumab plus bevacizumab, for as long as it can help you. You are free to stop this treatment at any time. 

      After finishing your treatment, you will still be contacted by the clinical trial doctor roughly every three months, as long as you agree to this. These check-ups may be over the phone or clinic visits and will include checks to see if you have had any side effects since your last dose and whether you have received any other treatments since.

      What happens if I am unable to take part in this clinical trial?

      If this clinical trial is not suitable for you, you will not be able to take part. Your doctor will suggest other clinical trials that you may be able to take part in or other treatments that you can be given. You will not lose access to any of your regular care.
