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.

4. Disease status requirement: Measurable disease defined as the presence of ≥ 1 nodal lesion that measures ≥ 1.5 cm in a single dimension as assessed by X-ray Computed Tomography (CT) (Positron Emission Tomography (PET/CT), or magnetic resonance imaging [MRI]

5. Eastern Co-operative Oncology Group (ECOG) performance status of ≤ 2.

6. For men and women of child-bearing potential, willing to use adequate contraception

Exclusion Criteria

1. Subject is a chronic alcoholic (intake > 35 units of alcohol (>5 bottles of wine weekly)) or drug abuser

2. Subject has any medical or psychiatric condition that, in the opinion of the Investigator, may compromise the subject's ability to participate in this study

3. Female subjects who are breastfeeding, pregnant, or plan to become pregnant during the study or within 3 months following the last dose of investigational product

4. Subjects with a current or recent history, as determined by the Investigator, of severe, progressive, and/or uncontrolled renal disease (estimated glomerular filtration rate (eGFR) <30ml/min), hepatic (Alanine transaminase (ALT) 2.5 times upper limit of normal (>2.5xULN), bilirubin > 2x ULN), hematological (absolute neutrophil count (ANC) <1.0 x 109/L, platelet count <75x109/L or requires regular platelet transfusions to maintain a platelet count ≥ 75 x 109/L , hemoglobin <9g/dL), endocrine (glycated Haemoglobin (HbA1c)>7% or random glucose >200mg/dL), pulmonary (Forced Expiratory Volume in 1 second (FEV1) <70% of predicted value), cardiac (New York Heart Association (NYHA)) class III/IV, or neurological disease

5. Has had an allogeneic stem cell transplant with current active graft-versus-host-disease.

6. Has known active central nervous system involvement of the malignancy.

7. Has active, serious infection requiring systemic therapy. Patients may receive prophylactic antibiotics and antiviral therapy at the discretion of the treating physician.
