简要总结
This research study is assessing a new drug, duvelisib, in combination with a drug that is already FDA approved, venetoclax, as a possible treatment for participants with CLL or those with Richter's Syndrome
详细描述
This is a Phase I/II clinical trial. A Phase I clinical trial tests the safety of an investigational drugs and also tries to define the appropriate dose of the investigational drugs to use for further studies. "Investigational" means that the drugs are being studied together for the first time.
This phase I study tests the safety of the drug duvelisib when used in combination with the drug venetoclax. Duvelisib is still being studied, but the FDA (the U.S. Food and Drug Administration) has approved the use of Duvelisib in patients with CLL/SLL with relapsed or refractory CLL after having received 2 or more prior therapies.
Duvelisib is a drug that is given in capsule form and taken by mouth. This drug is designed to stop cancer growth by blocking a protein called phosphatidylinositide 3-kinase (PI3K), which is important for the survival of CLL cells. In laboratory studies and in other clinical trials that included participants with CLL, duvelisib was effective at killing CLL cells.
Venetoclax is a tablet that is taken by mouth. Venetoclax targets a protein called BCL-2, which helps cancer cells survive. Venetoclax is an effective treatment for many participants with CLL who do not respond to chemotherapy or other approved drugs or who have relapsed after prior therapy.Venetoclax is FDA approved for participants with CLL who have never had therapy before or whose CLL has worsened after prior therapy.
In the phase I portion of this study, the investigators are looking to determine the dose of venetoclax that is safe to give with duvelisib and to see what the side effects are of this combination.

- •Platelet count ≥25,000 cells/mm3 (25 x 109/L) independent of transfusion within 7 days of screening
- •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

排除标准

结局指标
主要结局
Complete Response Rate (CRR)
时间窗: Response assessment on the end of cycle 3, 6 and 13. With 28 days per cycle.
The overall response rate (ORR) was defined as the proportion of participants achieving complete response (CR) based on IWCLL 2008 and Lugano 2014 criteria for RS.
