Summary

Background: * Papillary Renal Cell Cancer (RCC) is the second most common histologic subtype of kidney cancer, accounting for approximately 10-15% of cases * Type 1 papillary RCC occurs in both sporadic and hereditary forms, which are histologically identical. Non familial type 1 papillary RCC can present as both solitary renal tumors and as bilateral, multifocal disease * There are no standard agents of proven efficacy for patients with advanced papillary RCC. * Patients with disease localized to the kidney are managed surgically while patients with advanced/unresectable disease are usually managed in the community with vascular endothelial growth factor (VEGF) pathway antagonists or mechanistic target of rapamycin (mTOR) inhibitors. * Activating mutations of mesenchymal epithelial transition (MET) were identified in the germline of affected hereditary papillary renal cancer (HPRC) patients, who have a predilection for the development of bilateral, multifocal type 1 papillary RCC. Somatic MET mutations have been found in a subset of patients with non-inherited, sporadic papillary renal carcinoma * The investigational agent Capmatinib (INC280) is a selective MET inhibitor lacking activity against the VEGF pathway * This is a proof-of-concept study using INC280 in patients with papillary RCC to test the idea that effectively blocking the hepatocyte growth factor (HGF)/MET pathway will lead to clinical activity in patients with papillary renal cell cancer Objectives: Primary Objective: -To determine the overall response rate (Response Evaluation Criteria in Solid Tumors (RECIST) 1.1) in patients with papillary renal cell carcinoma treated with single agent INC280 Eligibility: * Diagnosis of hereditary papillary renal carcinoma (HPRC) or sporadic papillary renal cell carcinoma (RCC) * Patients with bilateral multifocal disease can have tumors localized to the kidney or have metastatic disease * Patients with sporadic papillary RCC (but without multifocal disease) should have advanced disease that is considered unresectable * Eastern Cooperative Oncology Group (ECOG) 0-2 * Measurable disease * Adequate organ function * No active brain metastases * Prior therapy * No more than 3 prior lines of systemic therapy * Prior therapy with a MET inhibitor is allowed as long as the patient has not had progressive disease while receiving the agent Design: * This is a phase 2 single center non-randomized trial. * The study will be conducted using a Simon 2 stage minimax design. Initially 13 evaluable subjects will be recruited. If there are no responses to therapy, the study will be terminated. If there is at least 1 response an additional 7 evaluable subjects will be accrued. * The two-stage minimax design is based on assuming an ineffective response rate of 5% and a targeted effective response rate of 25%. We also assume that the probability of accepting an ineffective treatment and the probability of rejecting an effective treatment are each 10%. * Subjects will be dosed orally at a starting dose of 600 mg twice daily. * The overall response rate (complete response + partial response) will be determined.

Eligibility Criteria

  • INCLUSION CRITERIA

2.1.1.1 Patients must have histologically or cytologically confirmed papillary Renal Cell Cancer (RCC).

  • Patients with bilateral multifocal disease can have tumors localized to the kidney or have metastatic disease
  • Patients with sporadic papillary RCC (but without multifocal disease) should have advanced disease that is considered unresectable

2.1.1.2 Patients must have measurable disease, defined as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded for non-nodal lesions and short axis for nodal lesions). Nodal lesions must be 15mm by computed tomography (CT) scan or magnetic resonance imaging (MRI). Non nodal lesions must be >10 mm with CT scan or MRI.

2.1.1.3 Patients must have normal organ and marrow function as defined below:

  • Hemoglobin > 9 g/dL (SI Units: 90 g/L)
  • Platelet count greater than or equal to 75 x 10 (9)/L
  • Absolute neutrophil count (ANC) greater than or equal to 1.5 x 10(9)/L without growth factor support
  • Total bilirubin less than or equal to 2 x upper limit of normal (ULN)
  • Aspartate aminotransferase (AST)/serum glutamic-oxaloacetic transaminase (SGOT) and/or alanine aminotransferase (ALT)/serum glutamate-pyruvate transaminase (SGPT) less than or equal to 2.5 x upper limit of normal (ULN)
  • Serum creatinine less than or equal to 1.5 x ULN
  • Asymptomatic serum amylase less than or equal to 2 x ULN; patients with > ULN but less than or equal to 2 x ULN serum amylase at study start must be confirmed to have no signs and/or symptoms suggestion pancreatitis or pancreatic injury (e.g., elevated P-amylase, abnormal imaging findings of pancreas, etc.)
  • Serum lipase less than or equal to ULN
  • Fasting serum triglyceride level less than or equal to 500 mg/dL

2.1.1.4 Patients may have had no more than 3 prior lines of systemic therapy. Prior therapy with a mesenchymal epithelial transition (MET) inhibitor is allowed as long as the patient has not had progressive disease while receiving the agent

2.1.1.5 Patient must be able to swallow and retain oral medication

2.1.1.6 Age greater than or equal to18 years.

2.1.1.7 Eastern Cooperative Oncology Group (ECOG) performance status 0 - 2.

2.1.1.8 Patients must provide written informed consent prior to any study procedures.

2.1.1.9 Patients must be willing and able to comply with scheduled visits, treatment plan and laboratory tests

EXCLUSION CRITERIA

2.1.2.1 Patients who are receiving any other investigational agents for treatment of their kidney cancer.

2.1.2.2 History of allergic reactions attributed to compounds of similar chemical or biologic composition to Capmatinib (INC280). Excipients in the current formulation include microcrystalline cellulose, mannitol, sodium starch glycolate, magnesium stearate and colloidal silicon dioxide

2.1.2.3 Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection requiring intravenous antibiotics, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements or potentially affect the interpretation of study data.

2.1.2.4 Subjects with significant or uncontrolled cardiovascular disease (e.g., uncontrolled hypertension, peripheral vascular disease, congestive heart failure, cardiac arrhythmia, or acute coronary syndrome) within 6 months prior to starting study treatment or heart attack within 12 months prior to starting study treatment

2.1.2.5 Patients receiving any medications that are known to be strong inducers or inhibitors of cytochrome P450 3A4 (CYP3A4), or sensitive substrates of CYP3A4, cytochrome P450 1A2 (CYP1A2), cytochrome P450 family 2 subfamily C member 9 (CYP2C9), cytochrome P450 2C19 (CYP2C19) or P-glycoprotein (P-gp) with a narrow therapeutic index.
