Early Phase Evaluation of ABC294640 in Patients With Refractory/Relapsed Diffuse Large B-cell Lymphoma or Kaposi Sarcoma

Summary

This is a sequential Phase I and IIa study to identify the maximum tolerated dose and to evaluate safety, tolerability, toxicity, pharmacokinetics and pharmacodynamics of the oral sphingosine kinase inhibitor ABC294640 specifically in patients with diffuse large B-cell lymphoma (DLBCL), including virus-associated (e.g., KSHV- or EBV-associated) DLBCL or Kaposi Sarcoma (KS) after failure of or intolerance to initial standard therapy.
