Efficacy and Safety Study of CC-4047 (Pomalidomide) to Treat Advanced Soft Tissue Sarcoma

Study Overview
=================
Brief Summary
-----------------
The purpose of the study is to determine the safety and efficacy of single agent CC-4047 (pomalidomide) in patients with advanced soft tissue sarcomas who have relapsed or are refractory to prior anticancer therapy.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of Participants With Adverse Events (AEs), Serious Adverse Events (SAEs), Deaths, or Discontinuations Due to AEs | An adverse event (AE) is defined as any noxious, unintended, or untoward medical occurrence occurring at any dose that may appear or worsen in a study subject during the course of a study. It may be a new intercurrent illness, a worsening concomitant illness, an injury, or any concomitant impairment of the study subject's health, including laboratory test values, regardless of etiology. A serious adverse event (SAE) is defined as any AE which: results in death; is life-threatening; requires inpatient hospitalization or prolongation of existing hospitalization; results in persistent or significant disability/incapacity; is a congenital anomaly/birth defect; constitutes an important medical event. National Cancer Institute (NCI) Common Toxicity Criteria for Adverse Events (CTCAE), Version 3.0, grades: 1 = mild, 2 = moderate, 3 = severe, 4 = life threatening, 5 = death. For more details, please see the Adverse Events section of this record. | AEs/SAEs were recorded from informed consent to 30 days post treatment discontinuation visit. Median treatment duration was 49 days (range: 3 to 102 days). | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Tumor Response as Assessed by the Response Evaluation Criteria in Solid Tumors (RECIST) Committee Guidelines | Changes in only the longest diameter (LD) of tumor lesions are used in RECIST criteria. Evaluation of target lesions: Complete Response (CR)=Disappearance of all target lesions; Partial Response (PR)=≥30% decrease in sum of the longest diameter (LD) of target lesions taking as reference the baseline sum LD; Progressed Disease (PD)=≥20% increase in sum of LD of target lesions taking as reference the smallest sum LD recorded since treatment started or the appearance of ≥1 new lesions; Stable Disease (SD)=Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD taking as reference the smallest sum LD since treatment started. For non-target lesions: CR= Disappearance of all non-target lesions and normalization of tumor marker level; Incomplete Response/SD=Persistence of ≥1 non-target lesions and/or maintenance of tumor marker level above normal limits; PD=Appearance of ≥1 new lesions; unequivocal progression of existing non-target lesions. | Assessed every 8 weeks for the first 8 months and then every 12 weeks thereafter, and at treatment discontinuation. Median treatment duration was 49 days (range: 3 to 102 days). |
