E.1.1 | Medical condition(s) being investigated |
Chronic Lymphocytic Leukemia |
|
E.1.1.1 | Medical condition in easily understood language |
CLL is a type of cancer that starts from cells that become certain white blood cells (called lymphocytes) in the bone marrow. The cancer cells start in the bone marrow but then go into the blood. |

E.2.1 | Main objective of the trial |
For subjects previously on Arms B, C, & D of Study UTX-TGR-304: To observe the overall response rate (ORR) defined as the sum of complete responses (CR) and partial responses (PR)
For subjects previously on Arm A of Study UTX-TGR-304: To evaluate the progression-free survival (PFS) and duration of response (DOR) |
|
E.2.2 | Secondary objectives of the trial |
For subjects previously on Arms B, C, & D of Study UTX-TGR-304: • To observe the progression-free survival (PFS) and duration of response (OR) • To observe the % of subjects that achieve MRD negativity • To observe the safety of ublituximab in combination with TGR-1202

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1.Prior treatment in clinical trial UTX-TGR-304 a.Confirmed progression by IRC from Arms B, C, or D after at least two cycles of treatment in trial UTX-TGR-304. There is no required timeframe to begin treatment on the UTX-TGR-204 protocol; however, if other therapies to treat the disease are implemented in the interim, the subject will not be eligible to enroll in the study. b.Non-progressing subjects from Arm A may be eligible for enrollment when protocol UTX-TGR-304 is completed 2.Adequate organ system function, defined as follows: a.Absolute neutrophil count (ANC) > 750 x 103/mm3 (0.75 K/μL) mL of blood / platelet count > 40 x 103/mm3 (40 K/μL) mL of blood unless cytopenias are related to bone marrow involvement. b.Total bilirubin ≤1.5 times the upper limit of normal (ULN) with the exception of Gilbert's Disease and Autoimmune Hemolytic Anemia. c.Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤2.5 x ULN if no liver involvement or ≤5 x the ULN if known liver involvement d.Calculated creatinine clearance >30 mL/min (as calculated by the Modified Cockcroft-Gault formula (using ideal body mass [IBM]). 3.ECOG performance status ≤ 2 4.Ability to swallow and retain oral medication 5.Willingness and ability to comply with trial and follow-up procedures, give written informed consent |
|
E.4 | Principal exclusion criteria |
1.Prior treatment with obinutuzumab + chlorambucil (Arm B subjects) or ublituximab (Arm C subjects) within 7 days of Cycle 1/Day 1. 2.Subjects refractory to (progressing on) UTX-TGR-304 Treatment Arm A (ublituximab + TGR-1202). 3.Known histological transformation from CLL to an aggressive lymphoma (i.e. Richter's transformation). 4.Evidence of chronic active Hepatitis B defined as Hepatitis B surface antigen positive or Hepatitis B DNA positive by PCR (HBV, NOT including subjects with prior hepatitis B vaccination who are Hepatitis B surface antibody positive only;) or chronic active Hepatitis C infection (HCV) defined as Hepatitis C RNA positive by PCR, cytomegalovirus (CMV) DNA positive by PCR, or known history of HIV. If HBc antibody, HCV antibody or CMV IgG and/or IgM antibody is positive the subject must be evaluated for the presence of HBV, HCV, or CMV by PCR - See Appendix D. 5.Evidence of ongoing systemic bacterial, fungal or viral infection, except localized fungal infections of skin or nails. NOTE: Subjects may be receiving prophylactic antiviral or antibacterial therapies at investigator discretion. Use of anti-pneumocystis pneumonia prophylaxis is required prior to Cycle 1/Day 1 and for the first 2 cycles. After cycle 2, is per investigator discretion. 6.Woman who are pregnant or lactating. 7.Live virus vaccines four (4) weeks prior to or during ublituximab therapy. |

E.5 End points |
E.5.1 | Primary end point(s) |
Overall response rate (ORR) ORR is defined as sum of CR and PR rates. Complete Response (CR) Rate CR rate is defined as the proportion of subjects who achieve a CR. Progression-free survival (PFS) PFS is defined as the interval from enrollment to the earlier of the first documentation of definitive disease progression or death from any cause. Definitive disease progression based on standard criteria (Hallek et al. 2008) and occurring for any reason (i.e., increasing lymphadenopathy, organomegaly or bone marrow involvement; decreasing platelet count, hemoglobin, or neutrophil count; or worsening of disease-related symptoms) other than lymphocytosis. Minimal Residual Disease (MRD) Negativity Rate MRD negativity rate is defined as the proportion of subjects who are MRD negative. Duration of response (DOR) DOR is defined as the interval from the first documentation of CR or PR to the earlier of the first documentation of definitive disease progression or death from any cause. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
During the study period, all subjects will be evaluated for response by CT and/or MRI. Evaluations are to be obtained at approximately cycles 3, 6 and 12. Following cycle 12, evaluations should occur at least every 12 cycles unless clinically indicated more frequently. The determination of response and progression will be based on IWCLL criteria (Hallek M, 2008) by the treating investigator |
|
E.5.2 | Secondary end point(s) |
For subjects previously on Arms B, C, & D of Study UTX-TGR-304: Progression-free survival (PFS) PFS is defined as the interval from enrollment to the earlier of the first documentation of definitive disease progression or death from any cause. Definitive disease progression based on standard criteria (Hallek et al. 2008) and occurring for any reason (i.e., increasing lymphadenopathy, organomegaly or bone marrow involvement; decreasing platelet count, hemoglobin, or neutrophil count; or worsening of disease-related symptoms) other than lymphocytosis. Duration of response (DOR) DOR is defined as the interval from the first documentation of CR or PR to the earlier of the first documentation of definitive disease progression or death from any cause. Minimal Residual Disease (MRD) Negativity Rate MRD negativity rate is defined as the proportion of patients who are MRD negative. For subjects previously on Arm A of Study UTX-TGR-304: Safety All Adverse Events (AE's) will be reported and evaluated using National Cancer Institute's Common Terminology Criteria (CTCAE) v4.0. |
