The Safety, Pharmacokinetic and Pharmacodynamic Effect of KA2237 (PI3 Kinase p110β/δ Inhibitor) In B Cell Lymphoma
Study Details
Study Description
Brief Summary
Multiple ascending dose study to evaluate safety/tolerability, pharmacokinetic and pharmacodynamics effects of KA2237 (PI3 Kinase p110β/δ Inhibitor) in patients with B Cell Lymphoma and determine the maximum tolerated dose (MTD) in Part I of the study. In Part II, patients with B cell lymphoma will be treated with KA2237 at the MTD to evaluate safety and efficacy in the patient population.

Outcome Measures
Primary Outcome Measures
- The occurrence of dose limiting toxicity (DLT); [Day 28 of treatment]
