Ascites or pleural effusion(s) are not acceptable as single sites of response assessment, but be present if measurable disease is present for evaluation. Have a ECOG Performance level of 1-2 (or Karnofsky 100-70). A lower ECOG Performance level is acceptable only if clearly due to non-oncologic problems (e.g., prior paraplegia from polio). Have a life expectancy of a least 6 months. Have recovered from any toxicities resulting from prior therapies (patients with alopecia will not be excluded). Are the trial subjects under 18? no Number of subjects for this age range: F.1.2 Adults (18-64 years) yes F.1.2.1 Number of subjects for this age range F.1.3 Elderly (>=65 years) yes F.1.3.1 Number of subjects for this age range
