Brief Summary

Chronic lymphocytic leukemia (CLL) is the most common leukemia in Western countries. The purpose of this study is to assess how well ABBV-453 works adult participants with relapsed/refractory (R/R) untreated CLL/small lymphocytic lymphoma (SLL). Adverse events, pharmacokinetics, and change in disease activity will be assessed. ABBV-453 is an investigational drug for the treatment of CLL and SLL. Participants will be enrolled with a specific target dose and receive obinutuzumab during the debulking period followed escalating doses of ABBV-453, until the appropriate target dose is achieved. Approximately 60 adult participants with previously R/R CLL/SLL will be enrolled in the study in approximately 40 sites across the world. Participants will receive intravenous (IV) obinutuzumab as part of the debulking period, followed by escalating doses of oral ABBV-453 until the appropriate target dose is achieved. The estimated study duration is 3 years. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, and checking for side effects.

Outcome Measures

Primary Outcomes (3)

  • Percentage of Participants With Adverse Events (AEs)

    An adverse event (AE) is defined as any untoward medical occurrence in a patient or clinical investigation participant administered a pharmaceutical product which does not necessarily have a causal relationship with this treatment. The investigator assesses the relationship of each event to the use of study. A serious adverse event (SAE) is an event that results in death, is life-threatening, requires or prolongs hospitalization, results in a congenital anomaly, persistent or significant disability/incapacity or is an important medical event that, based on medical judgment, may jeopardize the participant and may require medical or surgical intervention to prevent any of the outcomes listed above.

    Up to 3 Years

  • Maximum Administered Dose (MAD) of ABBV-453

    MAD is defined as the highest administered dose if no maximum tolerated dose (MTD) is determined.

    Up to 18 Months

  • Maximum Tolerated Dose (MTD) of ABBV-453

    MTD is defined as the highest dose administered that does not result in a final determination of de-escalate at that dose level.

    Up to 18 Months

Secondary Outcomes (10)

  • Maximum Observed Plasma Concentration (Cmax) of ABBV-453

    Up to 30 Months

  • Time to Maximum Observed Concentration (Tmax) of ABBV-453

    Up to 30 Months

  • Area Under the Plasma/Serum Concentration Versus Time Curve (AUC) of ABBV-453

    Up to 30 Months

  • Overall Response Rate (ORR)

    Up to 3 Years

  • Duration of Response (DOR) for Participants with PR/nPR or Better

    Up to 3 Years

  • +5 more secondary outcomes

Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Relapsed/refractory (R/R) chronic lymphocytic leukemia (CLL)/ small lymphocytic lymphoma (SLL) that has received at least 2 prior systemic therapies and have no available (or established) therapies known to provide clinical benefit and to which the participant would consent to receiving.
  • Laboratory values meeting those listed in the protocol.

You may not qualify if:

  • QT interval corrected for heart rate (QTc) using Fridericia's correction of \> 470 msec (females) or \> 450 msec (males), Grade 3 arrythmia, and/or other clinically significant cardiac abnormalities.
  • Known to be B-cell leukemia/lymphoma 2 inhibitor (BCL-2i) refractory or has received a BCL-2i-containing regimen within (6 months) of starting study drug (e.g., venetoclax, lisaftoclax, BGV-11417).
  • Has active human immunodeficiency virus (HIV) infection. HIV testing is not required unless required locally.
  • Recent history (within 6 months) of:
  • Congestive heart failure (defined as New York Heart Association, Class 2 or higher).
  • Ischemic cardiovascular event.
  • Cardiac arrhythmia requiring pharmacological or surgical intervention.
  • Pericardial effusion.
  • Pericarditis.
  • Consumes known moderate or strong inhibitors of cytochrome P450 3A isoform subfamily (CYP3A) within 14 day or 5 half-lives of the drug (whichever is shorter) before the first dose of ABBV-453.
