Clinical Trial Summary

This phase II trial studies the side effects of bevacizumab and anetumab ravtansine or paclitaxel in treating patients with ovarian, fallopian tube, or primary peritoneal cancer that does not respond to treatment (refractory). Bevacizumab is a monoclonal antibody that may interfere with the ability of tumor cells to grow and spread. Anetumab ravtansine is a drug that targets a protein in the body called mesothelin, which can be found in some ovarian, pancreatic and other tumors. Chemotherapy drugs, such as paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. It is not yet known whether giving bevacizumab and anetumab ravtansine or paclitaxel may work better in treating patients with ovarian, fallopian tube, or primary peritoneal cancer.

Description:

PRIMARY OBJECTIVES:

I. To assess the safety and tolerability of the combination of weekly anetumab ravtansine (anetumab) and bi-weekly bevacizumab.

II. To determine whether the progression free survival (PFS) of the combination weekly anetumab and bi-weekly bevacizumab is superior to weekly paclitaxel and bi-weekly bevacizumab.

SECONDARY OBJECTIVES:

I. To determine the overall response rate (ORR) according to Response Evaluation Criteria in Solid Tumors (RECIST) version (v)1.1.

II. To evaluate the pharmacokinetic (PK) profiles of weekly anetumab in serum and in peripheral blood mononuclear cells (PBMCs).

III. To evaluate anti-drug antibody (ADA) titers (only for patients receiving anetumab).

IV. To evaluate mononuclear phagocyte system (MPS) function, Fc-gamma receptors (FcgammaRs), hormone and chemokine mediators.

V. To correlate the expression of CA125 (immunohistochemistry [IHC] & serum) with mesothelin expression in archival tissue and circulating megakaryocyte potentiating factor (MPF).

VI. To investigate blood-based angiome profiling as a potential biomarker. VII. To characterize the molecular profile of archival tumor tissue using the Oncomine panel, and explore whether genomic mutations such as BRCA1/2 and homologous repair deficiency status are associated with clinical outcome.

EXPLORATORY OBJECTIVE:

I. To assess tumor tissue-based VEGF-dependent gene expression signature as a biomarker of response.

OUTLINE:

PHASE I: Patients receive anetumab ravtansine intravenously (IV) over 1 hour on days 1, 8, 15, and 22 and bevacizumab over 30-90 minutes IV on days 1 and 15. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.

PHASE II: Patients are randomized to 1 of 2 groups.

GROUP I: Patients receive anetumab ravtansine and bevacizumab as in Phase I.

GROUP II: Patients receive paclitaxel on days 1, 8, 15, and 22 and bevacizumab over 30-90 minutes IV on days 1 and 15. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 30-37 days and then every 8 weeks thereafter.

• Criteria only for the randomized phase 2 part: mesothelin screen positive determined from archival tumor tissue and to be performed centrally. MSLN-positive is defined as >= 30% of tumor cells with membrane staining intensities >= 2+. If an archival tumor specimen is unavailable, or unsuitable for mesothelin testing, a pre-treatment fresh tumor biopsy is required

• For the run-in-phase 1, patients will not be selected based on the mesothelin expression

• Patients with known brain metastases are not excluded from this clinical trial. Patients who received palliative radiation (for brain metastases) are eligible if they have been asymptomatic for at least 4 weeks without use of maintenance steroid therapy, and last received radiation at least 4 weeks prior to proposed start of therapy

• Ability to understand and the willingness to sign a written informed consent document. Patients with Impaired Decision Making Capacity (IDMC) can have a Legally Authorized Representative sign on their behalf.

Exclusion Criteria:

• Patients who have had chemotherapy or radiotherapy within 4 weeks (6 weeks for nitrosoureas or mitomycin C) prior to entering the study

• History of severe allergic reactions attributed to compounds of similar chemical or biologic composition to bevacizumab, anetumab ravtansine or paclitaxel

• Patients receiving any medications or substances that are strong inhibitors or inducers of CYP3A4 are ineligible. Because the lists of these agents are constantly changing, it is important to regularly consult a frequently-updated list or medical reference texts such as the Physicians' Desk Reference may also provide this information. As part of the enrollment/informed consent procedures, the patient will be counseled on the risk of interactions with other agents, and what to do if new medications need to be prescribed or if the patient is considering a new over-the-counter medicine or herbal product. Strong inhibitors and inducers of CYP3A4 are prohibited within 2 weeks before the start of and during treatment. Strong inhibitors and inducers of CYP2C8 should be used with caution; the PI of the study is to be consulted regarding their use

• Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, or psychiatric illness/social situations that would limit compliance with study requirements

• Pregnant women are excluded from this study because of the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother, breastfeeding should be discontinued during the study and for at least 6 months after last dose of study drugs. These potential risks may also apply to other agents used in this study. Women of child-bearing potential who do not agree to use adequate contraceptive measures during study therapy and for at least 6 months after the completion of study therapy will be excluded. Should a patient become pregnant or suspect she is pregnant while she is participating in this study, the patient should inform the treating physician immediately
