Participants with non-follicular indolent non-Hodgkin's lymphoma (iNHL) with MZL as the histology type received umbralisib, 800 milligrams (mg), orally, once daily (QD), until disease progression, unacceptable toxicity, or withdrawal from the study whichever occurred first.

Participants with non-follicular iNHL with WM as the histology type received umbralisib, 800 mg, orally, QD, until disease progression, unacceptable toxicity, or withdrawal from the study whichever occurred first.

Umbralisib

Bruce Cheson, MD

This research study will evaluate the safety and efficacy of a study drug called Umbralisib (also known as TGR-1202) alone as a possible treatment for Waldenstrom's Macroglobulinemia that has come back or that has not responded to standard treatment.

Study to Assess the Efficacy and Safety of Umbralisib in Participants With Non-Follicular Indolent Non-Hodgkin's Lymphoma

A Phase 2 Study to Assess the Efficacy and Safety of TGR-1202 (Umbralisib) Monotherapy in Patients With Non-Follicular Indolent Non-Hodgkin's Lymphoma

ORR for MZL=percentage of participants with complete response (CR)/partial response (PR). ORR for WM=CR/PR/very good partial response (VGPR)/minor response (MR). Response assessed per revised Lugano Classification for MZL \&per IWWM for WM participants. Per Lugano criteria CR=complete disappearance of all evidence of disease \& disease-related symptoms. PR=regression of measurable disease \& no new disease sites. Regression=≥50% decrease in the sum of the products of the diameters (SPD) of index lesions, with no increase in size of other lymph nodes/liver/spleen.Per IWWM criteria CR=disappearance of serum monoclonal immunoglobulin M (IgM) protein by immunofixation with a normal serum IgM level. VGPR=reduction of monoclonal IgM protein \>90% from baseline. PR=reduction of monoclonal IgM protein between 50-90% from baseline with regression of measurable disease. Regression defined in similar manner as Lugano Classification. MR=reduction of monoclonal IgM protein \>25% but \<50% from baseline.

DOR is defined as the time from documentation of a response to treatment to the first documentation of tumor progression or death due to any cause, whichever comes first.

CR rate is defined as percentage of participants who achieved CR. CR was assessed using Revised Response Criteria for Non- Hodgkin's Lymphoma (Lugano Classification) for participants with MZL and Consensus-Based 6th IWWM for participants with WM.

Per Lugano Classification, CR= the complete disappearance of all evidence of disease and disease-related symptoms i.e., liver/spleen non palpable and normal in size and disappearance of nodules related to lymphoma.

Per IWWM criteria, CR=disappearance of serum monoclonal IgM protein by immunofixation with a normal serum IgM level, liver/spleen non palpable and normal in size and disappearance of nodes related to WM.

PFS is defined as the interval from Cycle 1 (1 cycle = 28 days) Day 1 to the earlier of the first documentation of definitive disease progression or death from any cause. Assessment of progressive disease (PD) was based on Revised Response Criteria for non-Hodgkin's lymphoma, Lugano Classification for participants with MZL and consensus-based 6th IWWM for participants with WM.

Per Lugano Classification, PD was defined as the appearance of any new lesion more than 1.5 centimeters (cm) in any axis, even if other lesions are decreasing in size. At least a 50% increase from nadir in one of the following: SPD of index lesions, greatest transverse diameter (GTD) of any individual previously involved node, or GTD of any previously involved node provided that the GTD of that node is now ≥ 1.5 cm.

Per IWWM criteria participants, PD was defined as more than 25% increase in serum IgM level from lowest nadir and/or progression in clinical features attributable to the disease.

TTF is defined as a composite endpoint measuring time from Cycle 1/Day 1 to discontinuation of treatment for any reason, including disease progression, treatment toxicity, and death. PD was assessed based on Revised Response Criteria for non-Hodgkin's lymphoma, Lugano Classification for participants with MZL and consensus-based 6th IWWM for participants with WM.

Per Lugano Classification, PD was defined as the appearance of any new lesion more than 1.5 cm in any axis, even if other lesions are decreasing in size. At least a 50% increase from nadir in one of the following: SPD of index lesions, GTD of any individual previously involved node, or GTD of any previously involved node provided that the GTD of that node is now ≥ 1.5 cm.

Per IWWM criteria PD was defined as more than 25% increase in serum IgM level from lowest nadir and/or progression in clinical features attributable to the disease.

An AE is any untoward medical occurrence in a participant that does not necessarily have to have a causal relationship with the treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporarily associated with the use of a medicinal product, whether or not considered related to the medicinal product.
