Phase IV Randomization to On-Going Treatment to Evaluate Sustained Sorafenib

• Status: Terminated
• Trial end date: 2006-11-01
• Target enrollment: 0
• Participant gender: All

Summary

The purpose of this study is to see if taking interferon or gemcitabine along with sorafenib will stop the advanced renal cell cancer from becoming worse in some people. To do this, sorafenib along with gemcitabine or interferon will be compared to treatment with gemcitabine or interferon alone. More safety information on sorafenib will be also collected. About 260 patients with progressed renal cell cancer will be in this study.

• Phase: Phase 4
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: Bayer
• Treatments: Gemcitabine; Interferons; Niacinamide; Sorafenib

Exclusion Criteria:

• Patients must not have experienced more than three weeks from documented disease progression to randomization

• Any medical condition requiring the use of systemic corticosteroids during IFN therapy

• Previous or concurrent cancer that is distinct in primary site or histology from the cancer being evaluated in this study EXCEPT cervical carcinoma in situ, treated basal cell carcinoma, superficial bladder tumors (Ta, Tis & T1) or any cancer curatively treated within the last three years prior to study entry

• Severe renal impairment or receiving dialysis

• More than a two week interruption in sorafenib dosing immediately prior to randomization

• Patients with a best response of disease progression on their previous course of sorafenib

• Patients who meet the MSKCC high risk category at randomization

• Hemorrhagic episode >= Grade 2 NCI CTC AE v3.0 within last six months

• History of cardiac disease: congestive heart failure> NYHA class 2; active cardiovascular disease (MI more than six months prior to study entry is allowed); cardiac arrhythmia requiring anti-arrhythmic therapy (beta blockers or digoxin are permitted) or uncontrolled hypertension

• Active clinically serious bacterial or fungal infections (>= Grade 2 NCI CTCAE v3.0)

• Known history of Human Immunodeficiency Virus (HIV) infection or chronic hepatitis B or C

• Patients with seizure disorder requiring medication (such as steroids or anti-epileptics)

• Ongoing substance abuse, medical, psychological or social conditions that may interfere with the patients participation in the study or evaluation of the study results

• Known or suspected allergy to the investigational agent or any agent given in association with this trial, including history of sensitivity to E. coli-derived products

• Any condition that is unstable or that could jeopardise the safety of the patient and his/her compliance in the study. Patients with a history of severe depression; patients with clinically significant active autoimmune disorders; history of organ allograft

• Pregnant or breast-feeding patients. Women of childbearing potential must have a negative pregnancy test performed within seven days of the start of study treatment. Both men and women enrolled in this trial must use adequate birth control measures during the course of the trial

• Patients who have had a significant surgical procedure within the past four weeks are excluded

Excluded Therapies and Medications, Previous and Concomitant:

• Any prior or concurrent systemic anti-cancer therapy including chemotherapy, monoclonal antibodies, hormonal therapy or investigational therapy, except for bisphosphonates and sorafenib

• Biological response modifiers, such as G-CSF or GM-CSF, within three weeks prior to study entry or during study. G-CSF and other hematopoietic growth factors may only be used in the management of acute toxicity such as febrile neutropenia when medically indicated or at the discretion of the Investigator. However, they may not be substituted for a required dose reduction of any study drug

• Patients taking erythropoietin are permitted provided no dose adjustment is undertaken within two months prior to the study or during the study

• Concomitant rifampicin or St. John's Wart

• Palliative therapy will be allowed, patients may receive palliative and supportive care for any underlying illness
