A Pilot Study of the PI3K Inhibitor BKM120 in Patients With Relapsed Lymphoma


I. To evaluate the clinical benefit rate (complete response [CR], partial response [PR] or
standard disease [SD] >= 6 months) with BKM120 (PI3K inhibitor BKM120) in patients with
relapsed or refractory lymphoma.


I. To evaluate overall response rate, overall survival, progression-free survival and
duration of response.

II. To describe the toxicities associated with BKM120 in lymphoma. III. To evaluate
prognostic factors for aggressive lymphoma and whether there's a correlation with clinical


I. To assess serum cytokines before and after BKM120 therapy. II. To assess
phosphatidylinositol 3-kinase (PI3K) pathway member expression on paraffin-embedded tumor
samples pre-treatment.

III. To assess on paired fresh tumor tissue obtained from consenting patients pre- and
post-therapy the change in activation of PI3K pathway members.
