Interventional
Description of intervention(s) / exposure
Treatment: Drugs - ibrutinib
Treatment: Drugs - venetoclax
Treatment: Drugs - Placebo

Experimental: Fixed Duration (FD) Cohort: Open Label Ibrutinib + Venetoclax - Participants receive 420 mg of single-agent ibrutinib for first 3 cycles followed by ibrutinib plus venetoclax combination treatment (ibrutinib 420 mg and venetoclax 400 mg orally once daily on a continuous schedule) for 12 cycles (a cycle is defined by 28 days) or until disease progression or unacceptable toxicity.

Experimental: MRD Cohort/Confirmed Undetectable MRD (uMRD): Randomized to Ibrutinib (Blinded) - Participants receive 420 mg of single-agent ibrutinib for the first 3 cycles followed by ibrutinib plus venetoclax combination treatment for at least 12 cycles (a cycle is defined as 28 days) prior to randomization (pre-randomization phase).

Participants with confirmed uMRD are randomized to receive ibrutinib 420 mg orally once daily on a continuous schedule until MRD-positive relapse, disease progression (PD), or unacceptable toxicity.

After MRD-positive relapse or disease progression (PD) by iwCLL criteria, participants can reintroduce 400 mg venetoclax with a 5-week ramp up. If venetoclax is to be reintroduced, venetoclax treatment is to continue at the dose of 400 mg/day for up to approximately 2 years (cumulative) until PD or unacceptable toxicity.

Placebo comparator: MRD Cohort/Confirmed uMRD: Randomized Placebo (Blinded) - Participants receive 420 mg of single-agent ibrutinib for the first 3 cycles followed by ibrutinib plus venetoclax combination treatment for at least 12 cycles (a cycle is defined as 28 days) prior to randomization (pre-randomization phase).

Participants with confirmed uMRD are randomized to receive placebo orally once daily on a continuous schedule until MRD-positive relapse, PD or unacceptable toxicity.

If MRD-positive relapse or PD is confirmed after restaging per iwCLL criteria, participants can first reintroduce oral daily ibrutinib with the option of subsequently reintroducing 400 mg venetoclax with a 5-week ramp up, if subsequent disease relapse per iwCLL criteria occurs after ibrutinib reintroduction. If venetoclax is to be reintroduced, venetoclax treatment is to continue at the dose of 400 mg/day for up to approximately 2 years (cumulative) until PD or unacceptable toxicity.

Experimental: MRD Cohort/uMRD Not Confirmed: Randomized to Ibrutinib (Open-Label) - Participants receive 420 mg of single-agent ibrutinib for the first 3 cycles followed by ibrutinib plus venetoclax combination treatment for at least 12 cycles (a cycle is defined as 28 days) prior to randomization (pre randomization phase).

Participants with uMRD not confirmed are randomized to receive open-label ibrutinib 420 mg orally once daily on a continuous schedule until PD or unacceptable toxicity.

In case of confirmed PD after restaging per iwCLL criteria, participants can continue ibrutinib and reintroduce venetoclax treatment. If venetoclax is to be reintroduced, venetoclax treatment is to continue at the dose of 400 mg/day for up to approximately 2 years (cumulative) until PD or unacceptable toxicity.

Experimental: MRD Cohort/uMRD Not Confirmed: Randomized Ibrutinib + Venetoclax (Open-Label) - Participants receive 420 mg of single-agent ibrutinib for the first 3 cycles followed by ibrutinib plus venetoclax combination treatment for at least 12 cycles (a cycle is defined as 28 days) prior to randomization (pre randomization phase).

Participants with uMRD not confirmed are randomized to receive open-label ibrutinib 420 mg and venetoclax 400 mg orally once daily on a continuous schedule until PD or unacceptable toxicity. Venetoclax was allowed for administration up to 2 years cumulatively from first dose started in the pre-randomization phase to last dose in the randomization phase.


Treatment: Drugs: ibrutinib
ibrutinib administered orally once daily (three 140 mg capsules)

Treatment: Drugs: venetoclax
venetoclax tablets will be administered orally once daily starting with a 5 week ramp up of 20 mg, 50 mg, 100 mg, 200 mg and 400 mg. After ramp up, venetoclax will be administered at 400 mg.

Treatment: Drugs: Placebo
