Umbralisib and Rituximab as Initial Therapy for Patients With Follicular Lymphoma and Marginal Zone Lymphoma

Study Description
Brief Summary:
This research is being done to assess Umbralisib and Rituximab as a first line therapy for Follicular Lymphoma or Marginal Zone Lymphoma.

Condition or disease Intervention/treatment Phase
Lymphoma Follicular Lymphoma Follicular Lymphoma, Grade 1 Follicular Lymphoma Grade 2 Follicular Lymphoma Grade IIIa Marginal Zone Lymphoma Marginal Zone B Cell Lymphoma Drug: Umbralisib Drug: Rituximab Phase 2

Detailed Description:

This research study is a Phase II clinical trial. Phase II clinical trials test the safety and effectiveness of an investigational drug to learn whether the drug works in treating a specific disease. "Investigational" means that the drug is being studied.

The U.S. Food and Drug Administration (FDA) has not approved Umbralisib as a treatment for any disease.

The FDA has approved Rituximab as a treatment option for this disease.

Umbralisib is an investigational drug which blocks a protein called PI3K. PI3K is a protein that plays a role in the way cells grow. In this type of cancer, PI3K is increased and more active than usual. This helps the cancer cells to grow and survive. Early clinical trials have shown that Umbralisib can kill cancer cells in some patients and cause their tumors to shrink.

  • A treatment cycle is defined as 28 consecutive days.
  • Umbralisib will be administered at 800 mg by mouth once daily on days 1-28 of cycles 1-24.
  • Rituximab will be administered at 375 mg/m2 by intravenous infusion on Cycle 1 Day 1 and may be administered at 375 mg/m2 by intravenous infusion or at 1400 mg by subcutaneous injection on days 8, 15, 22 of cycle 1, day 1 of cycles 2 to 6, then every 8 weeks starting on day 1 of cycle 7 until completion of 24 cycles of umbralisib (i.e. every other cycle for 18 cycles or 9 doses, for a total of 15 doses of rituximab), or until progression or intolerance.

Other Name: TGR-1202

Drug: Rituximab
Rituximab works by targeting the CD20 antigen on normal and malignant B-cells. Then the body's natural immune defenses are recruited to attack and kill the marked B-cells

Prior radiation to a single site of disease is allowed if completed at least 2 weeks prior to initiation of protocol therapy and there are additional sites of measurable disease outside of the radiation field.
  • For patients with marginal zone lymphoma: No prior systemic therapy for marginal zone lymphoma. Prior radiation or surgical resection is allowed if there are additional sites of measurable disease outside of the radiation field. Prior radiation must be completed at least 2 weeks prior to initiation of protocol therapy. Prior H. pylori eradication therapy is allowed.
  • Age >18 years.
  • ECOG performance status ≤2
  • Participants must have adequate organ function as defined below:

    • total bilirubin <1.5 x institutional upper limit of normal (ULN) or <3 x ULN if considered due to Gilbert's syndrome
    • AST(SGOT)/ALT(SGPT) ≤2.5 × institutional upper limit of normal
    • creatinine within normal institutional limits OR
    • creatinine clearance ≥30 mL/min for participants with creatinine levels above institutional normal.
  • Participants must have adequate marrow function as defined below (unless abnormalities are considered related to marrow involvement by lymphoma):

    • absolute neutrophil count ≥1,000/mcL (500/mcL is acceptable if due to marrow involvement by lymphoma)
    • platelets ≥70,000/mcL(30,000/mcL is acceptable if due to marrow involvement by lymphoma)
  • Female participants who are not of child-bearing potential and female participants of child-bearing potential who have a negative serum pregnancy test within 3 days prior to initial trial treatment. Female participants of child-bearing potential and all male partners, and male participants must consent to use a medically acceptable method of contraception throughout the study period and for a minimum of 1 year after the last dose of rituximab and for a minimum of 4 months after the last dose of umbralisib.

Exclusion Criteria:

  • Participants who require immediate cytoreduction per the treating investigator.
  • For patients with H. pylori related gastric extranodal marginal zone lymphoma in the absence of t(11;18): Patient must have relapsed or refractory marginal zone lymphoma despite appropriate H. pylori eradication.
  • For patients with hepatitis C virus related marginal zone lymphoma: Patient must have relapsed or refractory marginal zone lymphoma despite appropriate treatment of hepatitis C virus infection.
  • Active systemic therapy for another malignancy within 2 years. Local/regional therapy with curative intent such as surgical resection or localized radiation is allowed if patient is deemed at low risk for recurrence by treating physician.

  • Evidence of chronic active Hepatitis B (HBV, not including patients with prior hepatitis B vaccination; or positive serum Hepatitis B antibody) or chronic active Hepatitis C infection (HCV), active cytomegalovirus (CMV), or known history of HIV. If HBc antibody is positive, the patient must be evaluated for the presence of HBV DNA (by PCR). If HCV antibody is positive, the subject must be evaluated for the presence of HCV RNA by PCR. If the patient is CMV IgG or CMV IgM positive, the subject must be evaluated for the presence of CMV DNA by PCR. Patients with positive HBc antibody and negative HBV DNA via PCR are eligible, but prophylaxis with entecavir or lamivudine is recommended. Subjects who are CMV IgG or CMV IgM positive but who are CMV DNA negative by PCR are eligible, but antiviral prophylaxis should be considered per institutional protocol.

  • Psychiatric illness/social situations that would limit compliance with study requirements
  • Known history of drug-induced liver injury, alcoholic liver disease, non-alcoholic steatohepatitis, primary biliary cirrhosis, ongoing extrahepatic obstruction caused by stones, cirrhosis of the liver.
  • Pregnant women are excluded from this study because rituximab is an agent with known potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with rituximab or umbralisib, breastfeeding should be discontinued if the mother is treated with rituximab or umbralisib. These potential risks may also apply to other agents used in this study.
