Incidence of Toxicity, Defined as Adverse Events Classified as Possibly, Probably, or Definitely Related to Study Treatment, Graded According to the Grading Scale for Hematologic Adverse Events in CLL Studies or Ordinal Common Toxicity Criteria (Phase I) Secondary · Up to 2 years

Overall toxicity incidence as well as toxicity profiles by dose level, patient and tumor site will be explored and summarized. Frequency distributions, graphical techniques and other descriptive measures will form the basis of these analyses. Here, we report the number of patients that reported a grade 2 or higher as their worst incidence of toxicity.

Sponsor's own description

This phase I/II trial studies the side effects and best dose of lenalidomide when given together with R-(-)-gossypol acetic acid and to see how well they work in treating patients with B-cell chronic lymphocytic leukemia (B-CLL) that has returned after a period of improvement (relapsed). Biological therapies, such as lenalidomide, may stimulate the immune system to attack cancer cells. R-(-)-gossypol acetic acid may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth and causing the cells to die. Giving lenalidomide with R-(-)-gossypol acetic acid may be an effective treatment for relapsed or refractory B-CLL. - Funding Source - FDA OOPD
