CC-4047 in Treating Patients With Advanced Solid Tumors That Did Not Respond to Treatment

OBJECTIVES:

Primary

• Determine the maximum tolerated dose of CC-4047 in patients with advanced refractory solid tumors.

Secondary

• Assess the safety of this drug in these patients.
• Assess the antitumor activity of this drug in these patients.
• Determine the effect of this drug on fetal hemoglobin levels in these patients.

OUTLINE: This is a open-label, uncontrolled, nonrandomized, dose-escalation, multicenter study.

• Treatment phase (course 1): Patients receive oral CC-4047 once daily on days 1-21 followed by a 7-day recovery period.

Cohorts of 3-6 patients receive escalating doses of CC-4047 until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience dose-limiting toxicity (DLT).

Patients with no clinical evidence of progressive disease or DLT after course 1 continue study treatment during the extension phase. Patients who develop a DLT during course 1 may continue study treatment at the discretion of the investigator.

• Extension phase: Patients continue taking CC-4047 at their assigned cohort dose as in course 1. Patients who tolerate a treatment-phase dose higher than the MTD continue treatment at the MTD. Courses repeat every 28 days for up to 24 months in the absence of disease progression or unacceptable toxicity.

Patients undergo blood collection at baseline and periodically during study to evaluate fetal hemoglobin levels.

After completion of study treatment, patients are followed at 28 days.
