Background
- Hereditary Leiomyomatosis and Renal Cell Cancer (HLRCC) is a familial cancer syndrome characterized by a propensity for developing renal cancer, and uterine and cutaneous leiomyomas. The kidney cancer associated with HLRCC is clinically aggressive and is characterized by unique histopathologic features that are sometimes described as type 2 papillary RCC.
- Germline mutations in the fumarate hydratase (FH) gene are the genetic hallmark of HLRCC. Mutational inactivation of FH has been shown to result in Von Hippel-Lindau (VHL)-independent upregulation of hypoxia inducible factor (HIF) and its downstream transcriptional targets.
- The recognition that HIF upregulation may play an important role in the formation and propagation of renal cancer associated with HLRCC suggests that interventions directed against components of this pathway, such as vascular endothelial growth factor (VEGF) and transforming growth factor-alpha/epidermal growth factor receptor (EGFR), may be of benefit in this patient population.
- We propose to test the hypothesis that dual VEGF/EGFR blockade with bevacizumab/erlotinib is likely to be clinically active in patients with HLRCC associated RCC as well as those with sporadic papillary sporadic RCC.
Objective
Primary Objective
-To determine the overall response rate (Response Evaluation Criteria in Solid Tumors (RECIST) in patients with 1) metastatic RCC associated with HLRCC and 2) metastatic sporadic/non-HLRCC papillary renal cancer treated with a combination of bevacizumab and erlotinib
Eligibility
- Diagnosis of advanced RCC associated with HLRCC (cohorts 1 and 3) or sporadic/non-HLRCC papillary RCC (cohorts 2 and 4)
- Eastern Cooperative Oncology Group (ECOG) PS 0-2
- Measurable disease, consistent with RECIST 1.1
- No history of major bleeding, recent or active myocardial ischemia, gastrointestinal (GI) perforation, cerebrovascular accidents or other significant intercurrent illness
- No coagulopathy or bleeding diathesis
- No recent surgery (< 4 weeks or inadequately healed surgical scars)
- Adequate organ function
- Adequate liver function (total bilirubin <= 1.5 mg/dL or < 3 x upper limit of normal (ULN) in subjects with Gilbert's disease, and aspartate aminotransferase (AST) serum glutamic oxaloacetic transaminase (SGOT)/alanine aminotransferase (ALT) serum glutamic pyruvic transferase (SGPT) 2.5 x ULN
- Adequate renal function (creatinine <= 2.0 x ULN or creatinine clearance > 30 mL/min
- Neutrophils >1500/microL and platelets >100,000
- No brain metastases
- No more than 2 prior regimens containing a VEGF-pathway inhibitor; no prior therapy with bevacizumab
- Ability to understand and sign informed consent
Design
- Patients will receive a fixed starting dose of bevacizumab (10mg/kg intravenous (IV) every 2 weeks) and erlotinib (150mg/day by mouth (po). Dose reductions and drug interruptions for unacceptable toxicity will be allowed.
- Patients will be evaluated for response every 8 weeks using RECIST criteria
- The study is based on an open label Simon two-stage minmax design in two cohorts, 1) cohort 1- patients with HLRCC, and 2) cohort 2- patients with sporadic papillary RCC. In each cohort, 13 patients will be accrued in the first stage and will accrue a maximum of 20 patients. Accrual into and analysis of the two cohorts will be independent.
- Following completion of accrual to cohorts 1 and 2, the study was expanded to include two additional cohorts- Cohort 3 (HLRCC patients and Cohort 4 (patients with sporadic/non HLRCC papillary RCC) to better estimate the overall response rate and to perform additional exploratory biomarker analyses. Up to 20 additional evaluable patients will be included in each of these cohorts.
