Maintenance Treatment With Bevacizumab and Atezolizumab for Ovarian Cancer
Halting Early Advancement of Residual Disease by Treatment With Bevacizumab and Atezolizumab in Ovarian Cancer
Study Overview
Status
Intervention / Treatment
Detailed Description
Atezolizumab and bevacizumab are a type of drug called a monoclonal antibody. Antibodies are proteins that are naturally found in the blood stream that fight infections. A monoclonal antibody is a special kind of antibody that is created in a laboratory that seeks out specific proteins in the body that may be involved in cancers to stop tumor growth.
When tumor cells start to die, broken down pieces of the tumor's DNA gets released into the blood stream, called circulating tumor DNA (ctDNA). Looking at ctDNA may be useful in determining whether the cancer is responding to treatment.
The purpose of this research study is to see whether looking at tumor DNA circulating in the bloodstream can help to determine which patients may respond to atezolizumab and bevacizumab and whether this drug combination is useful, when given as a maintenance treatment for patients with TP53 mutant ovarian, fallopian tube, or primary peritoneal cancer.

Description
Inclusion Criteria:
Pre-screening:

- Ability to understand and the willingness to sign a written Pre-screening Informed consent document.
- Patients must be receiving standard therapy for recurrent disease and have completed 3 cycles of platinum-based chemotherapy, with clinical benefit (in opinion of investigator). Patients with stable disease (in opinion of investigator) after 3 cycles of chemotherapy will also be eligible for pre-screening. There is no limitation on the number of prior lines of therapy.

- Eastern Cooperative Oncology Group (ECOG) performance status ≤2
- Patients must have a life expectancy ≥16 weeks
Main Study:
- Patients must have histologically confirmed TP53-mutant high grade serous or high grade endometrioid ovarian, fallopian tube, primary peritoneal cancer.
- Must have completed standard therapy for recurrent disease including at least 4 cycles of platinum-based chemotherapy with no clinical and radiographic evidence of disease progression on the post-treatment scan or a rising CA-125 level, following completion of standard therapy. Patients with stable disease and in response (as per Investigators opinion) following completion of chemotherapy will also be eligible for this study. There is no limitation on the number of prior lines of therapy.
- Following completion of platinum-based chemotherapy, patients must have residual disease detectable by TP53 ctDNA

- Ongoing prior toxicities related to previous treatments must be recovered to ≤ grade 2 at the time of registration
- Ability to understand and the willingness to sign a written informed consent document.
- Patients must receive first dose of study treatment within 8 weeks after their last dose of platinum based chemotherapy (last dose is the day of the last infusion)
- Postmenopausal or evidence of non-childbearing status for women of childbearing potential. Female patients of childbearing potential should use highly effective contraception and take active measures to avoid pregnancy while undergoing atezolizumab treatment and for at least 5 months after the last dose.

- Formalin fixed, paraffin embedded (FFPE) tumor sample from the primary cancer must be available.
- Pre-treatment CA-125 measurements must meet specific criterion
Exclusion Criteria:
Pre-screening:
- History of severe allergic reactions attributed to compounds of similar chemical or biologic composition to bevacizumab, or atezolizumab
- Uncontrolled intercurrent illness including, but not limited to, ongoing or active severe infection, symptomatic congestive heart failure, or psychiatric illness/social situations that (in the opinion of Investigator) would limit compliance with study requirements.
- History of abdominal fistula, gastrointestinal perforation or intra-abdominal abscess within 6 months prior to day 1.
Main Study:
- Patients who are receiving any other investigational agents or on-going chemotherapy.
- History of severe allergic reactions attributed to compounds of similar chemical or biologic composition to bevacizumab, or atezolizumab
- Uncontrolled intercurrent illness including, but not limited to, ongoing or active severe infection, symptomatic congestive heart failure, or psychiatric illness/social situations that (in the opinion of Investigator) would limit compliance with study requirements.
- History of abdominal fistula, gastrointestinal perforation or intra-abdominal abscess within 6 months prior to day 1.

- Major surgical procedure or significant traumatic injury within 28 days prior to Day 1 therapy, or open biopsy within 28 days prior to Day 1 therapy
- Anticipation of need for major surgical procedures during the course of the study
- Significant vascular disease within 6 months prior to Day 1
- Patients with known brain metastases should be excluded from this clinical trial because of their poor prognosis and because of the possible increased risk of bleeding if treatment with antiangiogenic agents is provided.
- Inadequately controlled hypertension, history of cerebrovascular accident, myocardial infarction or unstable angina, serious or inadequately controlled cardiac arrhythmia within 6 months.
- Patients with known hypersensitivity to Chinese hamster ovary cell products or other recombinant human antibodies.
- Resting ECG with QTcF > 470 msec or family history of long QT syndrome.

Patients with a history of localised breast cancer may be eligible, provided they completed their adjuvant chemotherapy more than three years prior to registration, and that the patient remains free of recurrent or metastatic disease
- Patients should be excluded if they have had prior treatment with anti-CTLA-4 antibody or any other antibody or drug specifically targeting T-cell co-stimulation. Previous treatment with anti-PD-1, anti-PD-L1 or anti-PD-L2 is not allowed.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Atezolizumab and Bevacizumab
A cycle will be every 3 weeks. Atezolizumab will be given intravenously (by vein) at a dose of 1200 mg once every cycle. Bevacizumab will be given intravenously at a dose of 15 mg/kg once every cycle. Up to 17 cycles of study treatment may be given. Participants may be able to receive the study treatment for more than 17 cycles if the participants and the study doctor thinks that they are benefiting. |
Atezolizumab is a humanized immunoglobulin (IgG1) monoclonal antibody that targets programmed death-ligand 1 (PD-L1) on tumor-infiltrating immune cells (ICs) or tumor cells (TCs) and prevents interaction with the programmed death-1 (PD-1) receptor and B7.1 (CD80), both of which function as inhibitory receptors expressed on T cells and other immune cells.
Other Names:
Bevacizumab is a recombinant humanized IgG1 monoclonal antibody that binds VEGF, a secreted factor that stimulates angiogenesis.
Bevacizumab prevents the interaction of VEGF with its receptors and neutralizes the biological activity of VEGF.
