Estimated Enrollment: 67
Study Start Date: July 2018
Estimated Study Completion Date: June 2024
Estimated Primary Completion Date: June 2022
Arms Assigned Interventions

Experimental:Duvelisib +Venetoclax,

Duvelisib will be given alone for the first seven days. On day 8 Venetoclax will be added. Duvelisib will be administered orally twice daily Venetoclax will be administered orally daily All patients will be admitted for administration of the initial dose of venetoclax at each dose escalation
Venetoclax targets a protein called BCL-2, which helps cancer cells survive.


Ages Eligible for Study: N/A-N/A

Genders Eligible for Study: All

  • Adequate hepatic function defined as:
  • -Serum aspartate transaminase (AST) and alanine transaminase (ALT) = 3.0 x upper limit of normal (ULN), bilirubin =1.5 x ULN (unless bilirubin rise is due to Gilbert's syndrome or of non-hepatic origin
  • Adequate renal function as defined as:
  • -Serum creatinine =1.5 times the upper limit of normal or creatinine clearance = 50 mL/min using a 24-hour urine collection
  • Women of child-bearing potential and men must agree to use adequate contraception (hormonal, barrier method or abstinence) prior to study entry and for the duration of study participation
  • Ability to understand and the willingness to sign a written informed consent document

Exclusion Criteria:

  • Previous treatment with venetoclax or duvelisib
  • Patients receiving cancer therapy (i.e., chemotherapy, radiation therapy, immunotherapy, biologic therapy, surgery within 2 weeks of Cycle 1/Day 1 with the following exceptions:
  • For patients on targeted therapies, a washout of least five half lives is required
  • Patients who experience clinical deterioration may start therapy after a shorter washout period with prior approval by the PI
  • Corticosteroid therapy (prednisone or equivalent <20 mg daily) is allowed
  • Confirmed central nervous system involvement
  • Allogeneic hematologic stem cell transplant within 6 months of starting study treatment or active graft vs. host disease (GVHD) requiring treatment or prophylaxis
  • History of active malignancy requiring therapy with the exception of hormonal therapy
  • Any active systemic infection requiring IV antibiotics or uncontrolled, active infections
  • Known history of human immunodeficiency virus (HIV), hepatitis C virus (HCV), or hepatitis B virus (HBV)
