Layout table for study information
Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 35 participants
Allocation: N/A
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase 2 Study to Assess the Efficacy, Safety, Pharmacokinetic and Pharmacodynamic Parameters of Umbralisib in Treatment Naïve Patients With Chronic Lymphocytic Leukemia (CLL)
Actual Study Start Date : November 12, 2019
Estimated Primary Completion Date : November 2022
Estimated Study Completion Date : November 2023

Arm Intervention/treatment
Experimental: Treatment with Umbralisib Drug: Umbralisib
800 mg Umbralisib will be self-administered on an outpatient basis. Umbralisib will be taken orally once daily within 30 minutes of a meal until removal from study. This treatment will be administered in 4 week (28-day) cycles.
Other Name: TGR-1202

Primary Outcome Measures :
  1. Overall Response Rate (Complete Response and Partial Response) [ Time Frame: Up to 24 months ]
    Overall Response Rate (ORR) of Umbralisib Treatment will be determined according to the criteria of the International Workshop on Chronic Lymphocytic Leukemia. ORR is defined as the percent of participants who achieve Complete Response (CR) or Partial Response (PR).

Secondary Outcome Measures :
  1. Progression Free Survival (PFS) [ Time Frame: Up to 24 months ]
    Progression Free Survival (PFS) is defined as the interval from registration to the earlier of the first documentation of definitive disease progression or death from any cause.

  2. Number of Participants with Serious Adverse Events [ Time Frame: Up to 24 months ]
    Number of participants with adverse events after receiving one dose of Umbralisib..

Exclusion Criteria:

  • Has ever received any form of treatment for CLL.
  • Corticosteroid therapy of prednisone > 10 mg or equivalent started at least 7 days prior to Cycle 1, Day 1 is prohibited. Prednisone ≤ 10 mg daily or equivalent is allowed as clinically warranted. Topical or inhaled corticosteroids are permitted.
