Two cohorts of patients will be enrolled: Cohort A will consist of patients who are current smokers, and Cohort B will consist of patients who are current nonsmokers. There will be 24 patients enrolled in each cohort. Nonsmokers are patients who have not consumed tobacco or nicotine-containing products for 1 year before the start of the study. Patients classified as current smokers must have smoked a minimum of 10 cigarettes per day for ≥1 year. Patients who have smoked 1-9 cigarettes per day for ≥1 year or more than 10 cigarettes per day for <1 year will not be eligible for this study.

Primary Purpose: Treatment
||Pharmacokinetic Trial of Sorafenib and Erlotinib in Patients With Refractory Solid Tumors
Primary Outcome Measures:
- To determine the pharmacokinetics (PK) of erlotinib when administered in combination with sorafenib on a continuous schedule in Refractory Solid Tumors in patients who are smokers and in patients who are nonsmokers. [ Time Frame: 3 months ] [ Designated as safety issue: No ]
Secondary Outcome Measures:
- To evaluate safety of this combination in patients with Refractory Solid Tumors. [ Time Frame: 3 months ] [ Designated as safety issue: Yes ]

Patients will receive erlotinib 150 mg once daily by mouth and sorafenib 400 mg twice daily by mouth. The study will begin with a 2-week run-in period (which will begin on Day 14 of the study, and continue through Day 1 of the study), in which erlotinib will be dosed alone at 150 mg once daily. Patients will continue taking erlotinib as a single agent at 150 mg once daily through Day 1. After the 2-week run-in period, patients will receive continuous dosing of both agents (erlotinib 150 mg once daily and sorafenib 400 mg twice daily) in cycles of 28 days each. Toxicity will be assessed every cycle (every 4 weeks) for all patients. Because this is not an efficacy study, restaging tumor measurements will be at the discretion of the physician every 8 weeks during treatment. Patients with objective response or stable disease will continue therapy; patients with disease progression or unacceptable toxicity will be discontinued from the study.
150 mg once daily by mouth
400 mg twice daily by mouth
Compared with supportive care alone, erlotinib has been associated with improved overall survival in patients with Refractory Solid Tumors; however, this absolute benefit is limited for the majority of patients. Incorporating other biologic agents into the second- or third-line treatment setting may prove to be a successful strategy in improving treatment efficacy (which has been recently demonstrated in several tumor types). Additionally, recent data suggest that smoking may influence the pharmacokinetic (PK) profile of erlotinib by increasing the metabolic clearance. Data suggest that the geometric mean erlotinib AUC(0-inf) and C(24h) are significantly decreased in smokers compared with nonsmokers (Hamilton et al. 2006). For this reason, this trial will enroll separate cohorts of patients who are current smokers and patients who are nonsmokers. Nonsmokers are patients who have not consumed tobacco or nicotine-containing products for 1 year before the start of the study. Patients classified as current smokers must have smoked a minimum of 10 cigarettes per day for ≥1 year.
|Ages Eligible for Study:
||18 Years and older
|Genders Eligible for Study:
|Accepts Healthy Volunteers:
- Histologically confirmed incurable solid tumors refractory to standard treatment or for which there is no known standard treatment.
- Two cohorts of patients will be enrolled: Cohort A will consist of patients who are current smokers, and Cohort B will consist of patients who are current nonsmokers. Nonsmokers are patients who have not consumed tobacco or nicotine-containing products for 1 year before the start of the study. Patients classified as current smokers must have smoked a minimum of 10 cigarettes per day for <1 year.
- Patients must have evaluable disease.
- Recovery from any toxic effects of prior therapy to grade 1 per the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 3.0.
- Completion of radiation therapy at least 21 days prior to the start of study treatment (not including palliative local radiation).
- An Eastern Cooperative Oncology Group (ECOG) performance status of 0-2.
- Absolute neutrophil count (ANC) >1,500/mL and platelets >75,000/mL (within 7 days prior to study treatment).
- Hemoglobin >9 g/dL (within 7 days prior to treatment). Patients may be transfused or receive erythropoietin to maintain or exceed this level where otherwise indicated.
- International normalized ratio (INR) <1.5 or prothrombin time (PT)/partial thromboplastin time (PTT) within normal limits (WNL) of the institution (if patient is not on anti-coagulation therapy; patients receiving anticoagulation treatment with an agent such as warfarin or heparin may be allowed to participate with the therapeutic range established prior to the initiation of study treatment).
- Serum creatinine <1.5 x the institutional upper limit of normal (ULN) within 7 days prior to study treatment. If the absolute value is greater than 2 mg/dL, the creatinine clearance (calculated according to the Cockroft-Gault formula) must be > 45 mL/min for the patient to be eligible for the study.

- Agreement of female patients of childbearing potential and male patients who have partners of childbearing potential to use an effective form of contraception to prevent pregnancy during treatment, and for a minimum of 90 days thereafter. Women of childbearing potential must have a negative serum pregnancy test performed within 7 days prior to the start of treatment.
- Patients with untreated brain metastases. Patients with neurological symptoms must undergo a CT scan/MRI of the brain to exclude brain metastasis. Patients who have a history of brain metastases that has been treated by surgery or radiation therapy > 4 weeks with no signs of CNS progression are allowed.
