Description:
A study to evaluate the safety and efficacy of venetoclax plus ibrutinib for participants
with T-cell Prolymphocytic Leukemia (T-PLL) and follows a 2-stage design as follows:
Stage 1: Enroll 14 participants with relapsed or refractory (R/R) T-PLL and move to Stage 2
if 4 or more participants meet protocol-specified response criteria. Response assessment will
be performed on a continued basis until all 14 participants have enrolled into Stage 1 and
have completed the Week 24 disease assessment.
Stage 2: Enroll up to an additional 23 participants.

Maximum Eligible Age: | N/A |
Minimum Eligible Age: | 18 Years |
Eligible Gender: | All |
Healthy Volunteers: | No |
Primary Outcome Measures
Measure: | Overall Response Rate (ORR) |
Time Frame: | Up to approximately 2 years |
Safety Issue: | |
Description: | ORR is defined as the percentage of participants achieving complete remission (CR), CR with incomplete bone marrow recovery (CRi), or partial response (PR) as their best response (per investigator assessment). |
Secondary Outcome Measures
Measure: | Progression-Free Survival (PFS) |
Time Frame: | Up to approximately 2 years |
Safety Issue: | |
Description: | PFS is defined as the time from the date of first dose of any study drug to the date of earliest disease progression or death. |
Measure: | Duration of Response (DOR) |
Time Frame: | Up to approximately 2 years |
Safety Issue: | |
Description: | DOR defined for participants who achieve a best overall response of CR, CRi, or PR, as the time from the date of first response (CR, CRi, or PR) to the earliest date of disease progression or death. |
Measure: | Time to Progression (TTP) |
Time Frame: | Up to approximately 2 years |
Safety Issue: | |
Description: | TPP is defined as the time from the date of the participant's first dose of any study drug to the date of earliest disease progression. |
Measure: | Event-free Survival (EFS) |
Time Frame: | Up to approximately 2 years |
Safety Issue: | |
Description: | EFS is defined as time from participant's first dose of any study drug to the date of earliest disease progression, death, or start of a new anti-T-PLL therapy. |
Measure: | Disease Control Rate (DCR) |
Time Frame: | Up to approximately 2 years |
Safety Issue: | |
Description: | DCR defined as the percentage of participants achieving CR, CRi, PR, or stable disease as best overall response. |
Measure: | Overall Survival (OS) Rate |
Time Frame: | Up to approximately 2 years |
Safety Issue: | |
Description: | OS is defined as the time from the date of the participant's first dose of any study drug to death from any cause. |
Measure: | Number of Eligible Participants Reaching Autologous or Allogeneic Transplantation |
Time Frame: | Up to approximately 2 years |
Safety Issue: | |
Description: | Number of eligible participants reaching autologous or allogeneic transplantation. |
Measure: | Number of Participants with Adverse Events (AE) |
Time Frame: | Up to approximately 2 years |
Safety Issue: | |
Description: | AE is defined as any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product and which does not necessarily have a causal relationship with this treatment. |
