Current Primary Outcome Measures  ICMJE
 (submitted: May 2, 2019)
Assess the safety profile, to determine the maximum tolerated dose and Recommended Phase Two Dose of ABT-199 when administered in combination with rituximab (R) in subjects with relapsed chronic lymphocytic leukemia and small lymphocytic lymphoma. [ Time Frame: Continuous dosing at designated dose level up to Month 6. At end of combination treatment, ABT-199 monotherapy may continue up to 8 years following the date of the last subject enrolled. If disease progression occurs, subjects may re-initiate ABT-199. ]
Protocol-defined events, which are attributed as having a reasonable possibility of being related to the administration of ABT-199 and/or rituximab, or can not be attributed by the investigator to a clearly identifiable cause such as tumor progression, concurrent illness, underlying disease or concomitant medication, will be considered a dose limiting toxicity.

Official Title  ICMJE A Phase 1b Study Evaluating the Safety and Tolerability of ABT-199 in Combination With Rituximab in Subjects With Relapsed Chronic Lymphocytic Leukemia and Small Lymphocytic Lymphoma
Brief Summary This is a Phase 1b, open-label, multicenter study evaluating the safety and tolerability of ABT-199 in combination with rituximab in up to 50 subjects with Relapsed Chronic Lymphocytic Leukemia and Small Lymphocytic Lymphoma. The primary objectives of this study are to assess the safety profile, to determine the maximum tolerated dose and establish the Recommended Phase Two Dose of ABT-199 when administered in combination with rituximab. The dose escalation portion of the study will include approximately 30 subjects. Once the recommended phase two dose and schedule have been determined, up to 20 additional subjects will be enrolled in an expanded safety portion of the study. Subjects who meet criteria for CR, CRi, or MRD-negative PR during the study may discontinue ABT 199. If disease progression occurs, as defined by iwCLL NCI/WG criteria for tumor response, or MRD progression, subjects may re-initiate ABT-199.
