A Safety and Dose-finding Study of JNJ-26483327, a Drug in Development for Cancer, for Patients With Advanced and/or Refractory Solid Malignancies.

JNJ-26483327, a multi-targeted reversible kinase inhibitor, is a new drug in development for treatment of cancer. This study will test the safety (the effect on the body) of JNJ-26483327 and the highest dose of JNJ-26483327 that patients with advanced cancer can tolerate will be determined. Antitumor activity of JNJ-26481585 will be evaluated.

JNJ-26483327 will be administered in a continuous regimen (orally twice daily) in 28-day treatment cycles. The dose of JNJ-26483327 will start low and will be increased during the study in groups of 1 to 6 patients. If a patient or a group of patients does not have severe side effects, the next group of patients will get a higher dose. The dose will increase until some patients have severe side effects. The dose will then be decreased to a dose level where severe side effects are observed in less than 1/3 of patients. Once a safe dose level has been determined an additional group of 12-18 patients will be treated. The amount of JNJ-26483327 in the blood will be measured and the effect of the disease will be evaluated in all patients.

Patients will be screened for eligibility within 4 weeks before study treatment is given. The treatment will consist of 28-day treatment cycles in a continuous twice daily dosing regimen.

During Cycle 1, patients are required to stay in the hospital for 2-3 nights and 2 full days. In addition there are 5 daytime visits during Cycles 1 and 2 (combined) that may take up to 6 hours after the morning dose. From Cycle 3 onwards, one hospital visit is required for each cycle of treatment.

Throughout the study, especially during Cycles 1 and 2, patients will undergo frequent blood and urine tests, procedures to assess safety including heart function, and tests to assess the course of the patient's illness. The duration of treatment will depend on adverse effects and whether there is benefit from the treatment. Two weeks after the last dose of the study drug, patients are required to return to the study site for follow-up assessments. Patients will take JNJ-26483327 capsules by mouth twice a day throughout treatment. Patients will be allowed to continue at the same dose level as long as there are no unacceptable side effects, and there is benefit to the patient based on the study doctor's evaluations.
