En undersøgelse til evaluering af virkningen af ​​Venetoclax på deltagere, der modtager en kovalent Brutons tyrosinkinasehæmmer (cBTKi) for førstelinjes kronisk lymfatisk leukæmi (1L CLL) for at opnå dybe varige remissioner for at tillade en periode uden for behandling (BRAVE)

6. november 2026 opdateret af: Genentech, Inc.

Fase II, åbent, prospektivt enkelt-arm, multicenter klinisk forsøg for at evaluere, om tilføjelse af Venetoclax til patienter på kovalent BTKi til 1L CLL kan opnå dybe varige remissioner (ved UMRD 10^-4) for at tillade en periode uden for behandling

The main purpose of the study is to evaluate if adding venetoclax to participants receiving cBTKi for the 1L CLL can achieve deep durable remissions of undetectable measurable residual disease [uMRD < or 10^-4 in peripheral blood (PB)] by end of combination treatment (EOCT) to allow off-treatment period.

The acronym BRAVE stands for Btki Responders to Achieve deep remission (or off-treatment periods) with VEnetoclax.

Deltagergruppe / Arm
Intervention / Behandling
Eksperimentel: Venetoclax Added to cBTKi (Commercially Prescribed)

Participants will receive venetoclax, orally, once daily (QD) with a starting ramp-up dose of 20 milligrams (mg) on Day 1 of Cycle 1 (cycle length= 28 days). The dose will increase weekly; thereafter, treatment will continue with venetoclax at the target dose of 400 mg, QD from Week 5 up to Day 28 of Cycle 12. Participant will discontinue from venetoclax and/or cBTKi after 12 cycles. Participants with detectable measurable residual disease with the presence of less than 1 CLL cell in 10,000 leukocytes (< 10^-4) (MRD4) or uMRD4 with partial response (PR) may continue receiving cBTKi-monotherapy (i.e. ibrutinib or acalabrutinib, or zanubrutinib) as previously prescribed by the investigator according to the prescribing label.

Venetoclax tablets will be administered as per the schedule specified in the arm.

Andre navne:
