Brief Summary:
This is an open-label, Phase II interventional study in order to assess efficacy and safety of single agent ublituximab as initial therapy for FL (Follicular lymphoma) and MZL (Marginal zone lymphoma ) with response driven addition of umbralisib for suboptimal response.

Condition or disease Intervention/treatment Phase
Marginal Zone Lymphoma Follicular Lymphoma Drug: Ublituximab Drug: Umbralisib Phase 2

Detailed Description:
Based on overall reporting in low tumor burden FL and MZL, CR rate of at least 30% was achieved when single agent rituximab was used in these subsets. The investigators assume that by administering ublituximab (both as a single agent and in combination with umbralisib for individuals who fail to achieve a CR [Complete response] with the single agent), the CR rate will increase to 50%. Efficacy will be assessed using the proportion of patients treated with ublituximab alone or with ublituximab administered in combination who have a complete response. Thus, the investigators will test the efficacy of ublituximab using a difference in proportions design by comparing an expected study population control rate of 50% to the comparison proportion being determined by the historical control CR rate of 30%. In other words, the null hypothesis is that the true response rate is 30%, and it will be formally tested against a one-sided alternative that the response rate is 50%.

Arm Intervention/treatment
Experimental: Treatment
Treatment-Naive Stage II (non-contiguous), Stage III, Stage IV FL + MZL will receive Ublituximab 900mg IV weekly x 4 doses. End of treatment assessment 8 weeks post last dose of single agent ublituximab will be performed. Patients who achieve less than a complete response will receive a combination of ublituximab AND umbralisib for a total of 12 cycles. (In the combination arm ublituximab will be administered on day 1,8 and 15 on cycle 1 and on day 1 on each cycle thereafter. Umbralisib will be administered at 800 mg daily for 12 cycles)
Drug: Ublituximab

Ublituximab will be administered as an intravenous infusion through a dedicated line. All infusions will be administered per institutional guidelines.

During ublituximab monotherapy (initial treatment), Cycle 1 Day 1 administration time frame: Over 4 hours. Cycle 1 days 8 and 15 will be over 3 hours, and Cycle 1 Day 22 will be over 90 minutes. During combination treatment with umbralisib, ublituximab will be administered over 90 minutes.


Drug: Umbralisib
Umbralisib will be administered orally once daily within 30 minutes of starting a meal.

  5. Measurable node must have an LDi greater than 1.5 cms. In the absence of nodal lesions, measurable extranodal disease should have an LDi greated than 1 cm. In patients with Splenic Marginal Zone lymphoma, in the absence of nodal lesions, spleen size should should be over 14 cms with evidence of lymphoma in the bone marrow biopsy.
  6. For low tumor burden lymphomas (as determined by GELF criteria) : Include patients diagnosed within 2 years of diagnosis. Low tumor burden patients diagnosed more than 2 years from study entry will be allowed provided patients have documented progression.

Prior Therapy Criteria

1. Patients must be untreated advanced stage disease (Stage III or Stage IV) or Stage II (noncontiguous). (Exception: Involved field or involved site radiation given for localized diagnosis is not considered a line of therapy).

Clinical/Laboratory Criteria

  1. Patients must be ≥ 18 years of age and be able to swallow and retain oral medication
  2. ECOG performance status of 0-2
  3. Patients must have adequate bone marrow function as evidenced by ANC ≥ 1000/µL and platelets ≥ 50,000µL and Hb >= 8g/dl within 28 days prior to registration unsupported by growth factors.
  4. Serum creatinine < 2.0 mg/dL or calculated creatinine clearance (CrCl) > 45 mL/min
