A Phase 2 Study of Bevacizumab, Erlotinib and Atezolizumab in Subjects With Advanced Hereditary Leiomyomatosis and Renal Cell Cancer (HLRCC) Associated or Sporadic Papillary Renal Cell Cancer
This phase II trial studies the effects of combination therapy with bevacizumab, erlotinib,
and atezolizumab in treating patients with hereditary leiomyomatosis and kidney cancer that
has spread to other places in the body (advanced). Bevacizumab is in a class of medications
called antiangiogenic agents. They work by stopping the formation of blood vessels that bring
oxygen and nutrients to tumors. This may slow the growth and spread of tumors. Erlotinib is
in a class of medications called kinase inhibitors. It works by blocking the action of a
protein called EGFR that signals cancer cells to multiply. This helps slow or stop the spread
of cancer cells. Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the
body's immune system attack the cancer, and may interfere with the ability of tumor cells to
grow and spread. Combination therapy with bevacizumab, erlotinib, and atezolizumab may
stabilize or shrink advanced hereditary leiomyomatosis and kidney cancer.
Description
PRIMARY OBJECTIVE:
I. To assess the complete response (CR) rate according to standard Response Evaluation
Criteria in Solid Tumors version 1.1 (RECIST 1.1) in patients with 1) advanced renal cell
cancer (RCC) associated with hereditary leiomyomatosis and renal cell cancer (HLRCC) and 2)
advanced sporadic/non-HLRCC papillary renal cell cancer treated with a combination of
bevacizumab, erlotinib, and atezolizumab.
SECONDARY OBJECTIVES:
I. To determine the safety and tolerability of the combination of bevacizumab, erlotinib, and
atezolizumab.
II. To determine the objective response rate (ORR) as complete response (CR) + partial
response (PR).
III. To determine disease control rate (DCR) - confirmed response, or stable disease (SD)
lasting for at least 6 months.
IV. To assess progression-free survival time (PFS) according to RECIST 1.1. V. To assess
overall survival (OS). VI. To assess the duration of response. VII. To assess response to
treatment using immune-modified Response Evaluation Criteria in Solid Tumors (iRECIST).
EXPLORATORY OBJECTIVES:
I. To evaluate immunologic modulation associated with the administered treatment regimen,
including
Ia. Peripheral immune subset analysis before and on treatment. Ib. Evaluation of relevant
soluble factors before and on treatment. (e.g., cytokine profiles) Ic. Tumor tissue immune
infiltration cells before and after treatment (immune microenvironment, CD8/CD4/CD3 cells,
T-Cell receptor clonality).
Id. Evaluation of tissue PDL1/PD1 expression and their correlation with outcome.
II. To assess specific genomic alterations (including FH, NRF2 pathway) and determine if
there is a correlation with clinical outcomes.
OUTLINE
Patients receive bevacizumab intravenously (IV) over 30-90 minutes and atezolizumab IV over
30-90 minutes on day 1 of each cycle. Patients also receive erlotinib orally (PO) once daily
(QD) on days 1-21 of each cycle. Cycles repeat every 21 days in the absence of disease
progression or unacceptable toxicity. Patients also undergo computed tomography (CT) with
contrast or CT without contrast and magnetic resonance imaging (MRI) throughout the trial.
Patients may also undergo a biopsy during screening, collection of blood throughout the
trial, and a brain MRI/CT scan with contrast and/or F-18 sodium fluoride positron emission
tomography (PET) scan as clinically indicated.
After completion of study treatment, patients are followed up every 6 months.
