Zusammenfassung der Studie

The study investigates the effect and safety of adding Atezolizumab to Bevacizumab and standard chemotherapy (Paclitaxel or Pegylated Liposomal Doxorubicin (PLD)) in women with recurrent ovarian cancer. The aim of this study is to determine whether the combination of Atezolizumab with Bevacizumab shrinks the tumor while preventing tumor cells from invading other parts of the body. Approximately 550 patients are expected to participate in this international study. Patients will be randomly assigned (known as randomization) to 2 treatment groups: chemotherapy plus Bevacizumab and Atezolizumab or chemotherapy plus Bevacizumab and placebo. Treatment assignment is done randomly by a computer, meaning that neither the patient nor the investigator can determine the treatment group. Atezolizumab is a new drug administered to people with various tumor diseases. It is approved by health authorities in Switzerland for the treatment of certain forms of lung cancer, bladder cancer, and breast cancer. Bevacizumab is also approved by health authorities in Switzerland for the treatment of various advanced cancers.

Untersuchte Intervention

• In the study, the medications are administered at specific time intervals, called cycles; one cycle lasts 4 weeks.

• Atezolizumab or placebo and Bevacizumab are administered every two weeks in conjunction with a non-platinum-based standard chemotherapy: Paclitaxel (administered weekly) or PLD (administered every four weeks). During the first four weeks, hospital visits occur weekly (a total of four visits). After that, visits depend on the standard chemotherapy regimen of the respective patient. All medications are given intravenously (i.v.), meaning through access directly into the vein.

• Before, during, and after the study, the health status of the patients is regularly monitored.

• During chemotherapy, the effect on the tumor is checked by radiological control every 9 weeks in the first year, then every 12 weeks.

• Study participants will be followed up after the end of the study treatment depending on the course of the disease.

• The duration of participation (number of cycles) depends on the tolerability of the therapy and the progression of the disease. However, the maximum duration of study treatment is 24 months.

• The study will last approximately 5 years in total.

recurrent ovarian cancer

(BASEC)

Kriterien zur Teilnahme
Women with advanced or recurrent ovarian, fallopian tube, or primary peritoneal cancer (peritoneal cancer) may participate and have had their first or second recurrence (relapse) within 6 months after platinum-based chemotherapy. Patients with a third recurrence may also participate if the platinum-based chemotherapy was given more than 6 months ago. The diagnosis must be confirmed by a tissue/tumor sample. Additionally, participants must be at least 18 years old. (BASEC)

Ausschlusskriterien
No patients may participate in this clinical trial if they have participated simultaneously or within 28 days prior to the start of this study in another clinical trial or another clinical research project, or have received another unapproved investigational drug or radiotherapeutic intervention. Patients with another serious illness or if a major surgery is planned in the near future are also not eligible for participation. Pregnant or breastfeeding women may not participate in this clinical trial. (BASEC)

Ein-/Ausschlusskriterien
Inclusion Criteria:

histologically proven relapse/progression

5. Mandatory de novo tumor biopsy (not older than 3 months) sent to central laboratory
as formalin-fixed, paraffin-embedded (FFPE) sample for determination of PDL1 status
prior to randomization for stratification.

6. Availability of a representative archival FFPE tumor sample (preferable from primary
diagnosis)

7. Patient has not progressed on the chosen/planned chemotherapy (PLD or Paclitaxel) in
any prior line
