* 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.

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.

Umbralisib

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

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

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.
