A clinical trial comparing atezolizumab with a placebo when given with chemotherapy (paclitaxel and carboplatin) and bevacizumab in people newly diagnosed with advanced ovarian, fallopian tube or peritoneal cancer.

How does the IMagyn050 clinical trial work?
This clinical trial is for patients who have advanced ovarian cancer, fallopian tube cancer or peritoneal cancer.  

The purpose of this clinical trial is to compare the effects, good or bad, of atezolizumab against placebo, when given with chemotherapy (paclitaxel and carboplatin) and bevacizumab, in patients with ovarian, fallopian tube or peritoneal cancer. If you take part in this clinical trial, you will be given either atezolizumab or a placebo, along with chemotherapy (paclitaxel and carboplatin) and bevacizumab.

How do I take part in this clinical trial?
To be able to take part in this clinical trial, you must have been recently diagnosed with advanced ovarian, fallopian tube or peritoneal cancer.

Your cancer needs to be a new cancer. Your cancer cannot be a previous cancer that has come back after treatment, including biological therapy, targeted therapy or hormone therapy. You also must not have had chemotherapy or radiation therapy for any cancers in the stomach area or pelvis. You will not be allowed to join the trial if you also have endometrial cancer.

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, if you are not currently pregnant but can become pregnant, you 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 be split into 2 groups depending on whether or not they have already had surgery before entering the trial:
 

Group 1 – treatment for patients who have already had surgery
Everyone in this group will have had surgery before joining the study. During that surgery, their surgeon will have removed as much cancer as possible. The patients in this group will be split into 2 sub-groups randomly (like flipping a coin) and given either:

• Atezolizumab, chemotherapy and bevacizumab (all given as infusions into your vein every 3 weeks)
• OR placebo, chemotherapy and bevacizumab (all given as infusions into your vein every 3 weeks)

You will be given a total of 22 rounds of treatment, but not all of the treatments will be given each time:

• The first round of treatment will only include chemotherapy and atezolizumab OR placebo (you will not receive bevacizumab)
• The next 5 rounds of treatment will include all three treatments (chemotherapy, bevacizumab and atezolizumab OR placebo)
• The next 16 rounds of treatment will only include bevacizumab and atezolizumab OR placebo (you will not receive chemotherapy)

You will have a 1 in 2 chance of being placed in the group being given atezolizumab or the group being given placebo.

Group 2 – surgery after treatment has started
Everyone in this group will have surgery during the study. Patients in this group will be split into 2 sub-groups randomly (like flipping a coin) and given either:

• Atezolizumab, chemotherapy and bevacizumab (all given as infusions into your vein every 3 weeks)
• OR placebo, chemotherapy and bevacizumab (all given as infusions into your vein every 3 weeks)

You will be given a total of 22 rounds of treatment, but not all of the treatments will be given each time:

• The first 2 rounds of treatment will include all three treatments (chemotherapy, bevacizumab and atezolizumab OR placebo)
• Your surgery to remove the cancer will happen after 3 rounds of treatment. The treatments just before and just after your surgery (treatment rounds 3 and 4) will only include chemotherapy and atezolizumab OR placebo (you will not receive bevacizumab)
• The next 16 rounds of treatment will only include bevacizumab and atezolizumab OR placebo (you will not receive chemotherapy)

You will have a 1 in 2 chance of being placed in the group being given atezolizumab or the group being given placebo.

This is a ‘placebo-controlled’ clinical trial, which means that one of the groups will be given medicine with no active ingredients (also known as a ‘placebo’). A placebo is used to show that the doctor or the patients do not sway the results of the clinical trial. All patients will be given chemotherapy and bevacizumab, which are the current standard treatments for ovarian, fallopian tube or peritoneal cancer.

Neither you nor your clinical trial doctor can choose or know the group you are in. However, your clinical trial doctor can find out which group you are in, if your safety is at risk. If your cancer gets worse while you are on this trial and the doctor wants to change your treatment or put you on a different clinical trial, no one will be able to tell you whether or not you were given atezolizumab or placebo until this clinical trial is completely finished. Not having this information might mean that you are not suitable to take part in other clinical trials testing new drugs.

How often will I be seen in follow-up appointments, and for how long?
You will be given the clinical trial treatment atezolizumab OR placebo, with paclitaxel, carboplatin and bevacizumab for about 1 year and 3 months. You are free to stop this treatment at any time. After being given treatment, you will still be seen regularly by the clinical trial doctor every 3–6 months. These hospital visits will include checks to see how you are responding to the treatment and any side effects that you may be having. Your doctor will explain all of the hospital visits and checks to you if you would like to take part in the trial.

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.
