The treatment

How it is intended to work

This is how the treatment is meant to work. Whether it helps, and how safe it is, is what this trial is testing.

Treatments listed in the registry

  • Acalabrutinib (Drug): Acalabrutinib is an orally available cBTKi that inhibits the activity of BTK and prevents the activation of the B-cell antigen receptor (BCR) signaling pathway.
  • Venetoclax (Drug): Venetoclax is an orally bioavailable inhibitor of the anti-apoptotic protein BCL-2

The study

Treatment groups

Non Randomized · Single Group · masking: None

Acalabrutinib and Venetoclax (Experimental)

For Cohort 1, each participant will be in the study for approximately 5 years (60 months) counting from C1D1, starting with 2 cycles of acalabrutinib lead-in treatment, followed by 12 cycles of AV combination treatment, and 4 years of follow-up. For Cohort 2, each participant will be in the study for approximately 5 years (60 months) counting from C1D1 starting with 2 cycles of acalabrutinib lead-in treatment, followed by 22 cycles of AV combination treatment, and 3 years of follow-up.

Goals

What the study measures

Main goals

  • Overall Response Rate (ORR) (ORR assessed at multiple timepoints during treatment period (each cycle is 28 days) and then every 12 months through the study completion, for 5 years. Timepoint for primary analysis is at completion of cycle 14.)

Other goals

  • Progression Free Survival (PFS)
  • Duration of Response (DoR)
  • Event Free Survival (EFS)
  • Time to Next Treatment (TTNT)
  • Overall Survival (OS)
  • Rate of undetectable Minimal Residual Disease (uMRD)
  • Treatment-Emergent Adverse Events (safety and tolerability) of second-line (2L) treatment with Acalabrutinib and Venetoclax after relapse following 1L cBTKi + BCL2i

Planned enrollment: 80 (estimated).
