This phase I trial studies the side effects and best dose of tipifarnib when given together with sorafenib tosylate in treating patients with biopsiable advanced cancer. Tipifarnib and sorafenib tosylate may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the cancer.

Primary Outcome Measures:
  • MTD defined as the highest dose level in which fewer than 2 patients experience a dose limiting toxicity as graded by the National Cancer Institute Common Terminology Criteria for Adverse Events version 4.0 [ Time Frame: 28 days ] [ Designated as safety issue: Yes ]
    Descriptive statistics and graphical analysis will be used to summarize the data. Categorical variables will be summarized in frequency tables.

Secondary Outcome Measures:
  • Clinical response evaluated using Response Evaluation Criteria In Solid Tumors criteria [ Time Frame: Up to 4 weeks ] [ Designated as safety issue: No ]
    Descriptive statistics and graphical analysis will be used to summarize the data. For continuous variables, mean (standard deviation) or median (range) will be used to summarize outcomes.

  • Signaling pathway inhibition in tumor tissue by RPPA [ Time Frame: Up to 4 weeks ] [ Designated as safety issue: No ]
    The analysis of the activated signaling pathways using Pathway Analysis (Ingenuity) will determine whether particular molecular profiles are likely to respond to tipifarnib and sorafenib.

Estimated Enrollment: 56

Detailed Description:


I. To evaluate the safety and toxicity and to determine maximum tolerated dose (MTD) of tipifarnib in combination with sorafenib (sorafenib tosylate).


I. Preliminary assessment of tipifarnib and sorafenib efficacy (objective response).

II. To determine signaling pathway profiles of patients treated with tipifarnib and sorafenib who are amenable to biopsy by reverse phase protein microarray (RPPA) analysis.

OUTLINE: This is a dose-escalation study of tipifarnib.

Patients receive sorafenib tosylate orally (PO) once daily (QD) or twice daily (BID) on days 1-28 and tipifarnib PO QD or BID on days 1-21. Treatment repeats every 28 days for 12 courses in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up for 4 weeks.


Ages Eligible for Study:   18 Years and older

Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Patients must have had =< 4 prior chemotherapy regimens; patients must have advanced cancer that is refractory to standard therapy or for whom there is no standard therapy that increases survival by three months
  • Eastern Cooperative Oncology Group (ECOG) performance status =< 2 (Karnofsky >= 60%)
  • Life expectancy of greater than 12 weeks
  • Leukocytes >= 3,000/mcL
  • Absolute neutrophil count >= 1,500/mcL
  • Platelets >= 100,000/mcL
  • Total bilirubin =< 1.5
  • Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase [SGOT])/alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase [SGPT]) =< 2.5 x institutional upper limit of normal
  • Creatinine within normal institutional limits OR creatinine clearance >= 60 mL/min/1.73 m^2 for patients with creatinine levels above institutional normal (a calculated creatinine clearance [CrCL] is acceptable)
  • International normalized ratio (INR)/prothrombin time (PT) =< within institutional guidelines for biopsy procedures (=< 16 seconds)
  • Eligibility of patients receiving any other medications or substances known to affect or with the potential to affect the activity or pharmacokinetics of BAY 43-9006 (sorafenib tosylate) or R115777 (tipifarnib) will be determined following review of their case by the Principal Investigator
  • Women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation; should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately
  • Ability to understand and the willingness to sign a written informed consent document
  • Tumor accessible for repeat biopsies

Exclusion Criteria:

  • Patients who have had chemotherapy or radiotherapy within 4 weeks (6 weeks for nitrosoureas or mitomycin C) prior to entering the study or those who have not recovered from adverse events due to agents administered more than 4 weeks earlier
  • Patients may not be receiving any investigational agents other than BAY 43-9006 and R115777
  • Patients with known brain metastases are excluded except for patients who have had treated brain metastases and are currently not taking anti-seizure medications or steroids
  • Patients may not have allergies to imidazoles (e.g., clotrimazole, ketoconazole, miconazole, econazole) or a history of allergic reactions attributed to any other compound of similar chemical or biologic composition to either BAY 43-9006 or R115777
  • Uncontrolled hypertension with systolic blood pressure of > 140 mmHg or diastolic pressure > 90 mmHg; however, patients with well-controlled hypertension are eligible
  • Patients must not have any evidence of current history of bleeding diathesis
  • Patients cannot be on therapeutic anticoagulation; prophylactic anticoagulation therapy (e.g., low-dose warfarin) of venous or arterial access devices is allowed provided that the requirements for prothrombin time (INR; international normalized ratio of prothrombin time) and partial thromboplastin time (PTT) are maintained; patients will be monitored on a weekly basis for the first (1st) cycle of treatment until the INR/PT has stabilized for 2 weeks consecutively; if patients discontinue the R115777 patients will be monitored weekly until INR/PT is stabilized for 2 weeks consecutively
