Excerpt:
...- Cohort 2: Untreated patients with high-risk features (del(17p), or mutated TP53, or del(11q), or unmutated IGHV, or >= 65 years of age) are eligible (cohort 2) provided they have active disease requiring treatment as defined by the International Working Group for CLL (IWCLL)...

Title:
4635 Combined Ibrutinib and Venetoclax for First-Line Treatment of Patients with Chronic Lymphocytic Leukemia (CLL): 5-Year Follow-up Data
Published date:
11/02/2023
Excerpt:
We report long term follow-up of combined IBR and VEN in first-line CLL (n=120) with a 5-year PFS of 90.1%. The 5-year PFS for pts with del(17p)/TP53 mutation is 86.1%. Retreatment with BTK inhibitor appears effective for pts with disease relapse.

Fixed-duration ibrutinib + venetoclax for first-line treatment of chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma (SLL): 4-y follow-up from the FD cohort of the phase 2 CAPTIVATE study.
Published date:
05/25/2023
Excerpt:
Pts aged ≤70 y with previously untreated CLL/SLL received 3 cycles of I then 12 cycles of I+V (I 420 mg/d orally; V ramp-up to 400 mg/d orally)….4 y PFS rates were numerically lower in pts with uIGHV (73%) or del(17p) and/or TP53 mutation (63%), while OS rates remained consistently high (Table)....With 4 y follow-up, fixed-duration I+V continues to provide deep, durable remissions with clinically meaningful PFS and time off treatment, including in pts with high-risk disease features.

Ibrutinib Plus Venetoclax for First-line Treatment of Chronic Lymphocytic Leukemia
Published date:
06/10/2021
Excerpt:
Patients were required to have at least 1 of the following features: del(17p), TP53-mutated CLL, del(11q)...Therapy consisted of ibrutinib, 420 mg/d, monotherapy for 3 cycles, thereafter combined with venetoclax....The 3-year progression-free survival was 93%, and 3-year overall survival was 96%....Remissions appeared to be durable during a follow-up of more than 3 years, with activity seen across high-risk disease subgroups, including those with del(17p)/TP53-mutated CLL.

Fixed-duration (FD) first-line treatment (tx) with ibrutinib (I) plus venetoclax (V) for chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma (SLL): Primary analysis of the FD cohort of the phase 2 captivate study.
Published date:
05/21/2021
Excerpt:
In pts with del(17p)/TP53 mutation (n=27), CR rate was 56%, uMRD rate was 81% (PB) and 41% (BM), and 24-mo PFS was 84% (95% CI 63–94). Of 34 pts with high baseline TLS risk based on tumor burden, 32 (94%) shifted to medium or low risk after I lead-in; no TLS occurred....First-line I+V is an all-oral, once-daily, chemotherapy-free, fixed-duration regimen that provides deep, durable responses in pts with CLL/SLL, including those with genomic high-risk features.
