Safety and Efficacy of KRT-232 in Combination With Acalabrutinib in Subjects With R/R DLBCL or R/R CLL
Study Details
Study Description
Brief Summary
This study evaluates KRT-232, a novel oral small molecule inhibitor of MDM2, combined with acalabrutinib for the treatment of adults with Diffuse Large B-Cell Lymphoma and Chronic Lymphocytic Leukemia. Participants must be relapsed/refractory (having failed prior therapy)

Outcome Measures
Primary Outcome Measures
- Primary Objective Phase 1b:To determine the KRT-232 maximum tolerated dose/ maximum administered dose (MTD/MAD) and recommended Phase 2 Dose (RP2D) in combination with acalabrutinib in subjects with R/R DLBCL or R/R CLL [56 Days]
Endpoint/Outcome Measures: Dose-limiting toxicities will be used to establish the MTD/MAD of KRT-232 in combination with acalabrutinib. The Safety Review Committee will determine the RP2D based on safety data of the combination of KRT-232 and acalabrutinib.
- Primary Objective Phase 2: Cohort 1: To determine the complete response (CR) [1 Year]
Endpoint/Outcome Measures: Cohort 1: The proportion of subjects with CR as assessed by investigators per the Lugano Classification.
- Primary Objective Phase 2: Cohort 2: To determine the rate of CR/complete remission with incomplete hematologic recovery (CRi) rate in R/R CLL [1 Year]
Endpoint/Outcome Measures: Cohort 2: The proportion of subjects with CR/CRi as assessed by investigators per iwCLL Response Criteria.
Secondary Outcome Measures
- Phase 1b Secondary Objective: Pharmacokinetic (PK) profile [Baseline, 1, 2, 4, 6 and 24 hours post dose on days 1 and 2 of cycle 1 (each cycle is 28 days); Baseline and 2 hours post dose on day 1 and 24 hours post dose on day 8 of cycle 2]
Endpoint/Outcome Measures: Will be measured using liquid chromatography/tandem mass spectrometric method. Standard descriptive methods (point estimates and confidence intervals, scatterplots) will be used to summarize the baseline levels and the changes from baseline (i.e. after treatment). The individual PK parameter from a single dose will be estimated maximum concentration (Cmax).
- Phase 1b Secondary Objective: Pharmacokinetic (PK) profile [Baseline, 1, 2, 4, 6 and 24 hours post dose on days 1 and 2 of cycle 1 (each cycle is 28 days); Baseline and 2 hours post dose on day 1 and 24 hours post dose on day 8 of cycle 2]
Endpoint/Outcome Measures: Will be measured using liquid chromatography/tandem mass spectrometric method. Standard descriptive methods (point estimates and confidence intervals, scatterplots) will be used to summarize the baseline levels and the changes from baseline (i.e. after treatment). The individual PK parameters from a single dose will be area under the curve (AUC).
- Phase 1b Secondary Objective: Pharmacokinetic (PK) profile [Baseline, 1, 2, 4, 6 and 24 hours post dose on days 1 and 2 of cycle 1 (each cycle is 28 days); Baseline and 2 hours post dose on day 1 and 24 hours post dose on day 8 of cycle 2]
Endpoint/Outcome Measures: Will be measured using liquid chromatography/tandem mass spectrometric method. Standard descriptive methods (point estimates and confidence intervals, scatterplots) will be used to summarize the baseline levels and the changes from baseline (i.e. after treatment). The individual PK parameters from a single dose will be half-life (T1/2).
- Phase 1b Secondary Objective: Pharmacokinetic (PK) profile [Baseline, 1, 2, 4, 6 and 24 hours post dose on days 1 and 2 of cycle 1 (each cycle is 28 days); Baseline and 2 hours post dose on day 1 and 24 hours post dose on day 8 of cycle 2]
Endpoint/Outcome Measures: Will be measured using liquid chromatography/tandem mass spectrometric method. Standard descriptive methods (point estimates and confidence intervals, scatterplots) will be used to summarize the baseline levels and the changes from baseline (i.e. after treatment). The individual PK parameter from a single dose will be apparent clearance.
- Phase 1b Secondary Objective: Pharmacokinetic (PK) profile [Baseline, 1, 2, 4, 6 and 24 hours post dose on days 1 and 2 of cycle 1 (each cycle is 28 days); Baseline and 2 hours post dose on day 1 and 24 hours post dose on day 8 of cycle 2]
Endpoint/Outcome Measures: Will be measured using liquid chromatography/tandem mass spectrometric method. Standard descriptive methods (point estimates and confidence intervals, scatterplots) will be used to summarize the baseline levels and the changes from baseline (i.e. after treatment). The individual PK parameters from a single dose will be apparent volume of distribution using non-compartmental or compartmental PK methods with the software WinNonlin.
- Phase 2 Secondary Objective: Cohort 1 (R/R DLBCL): To determine the overall response rate (ORR) for R/R DLBCL subjects. [2 Years]
Endpoint/Outcome Measures: The proportion of subjects who achieve a partial response (PR) or better at any time point while on study.
- Phase 2 Secondary Objective: Cohort 2 (R/R CLL): To determine the ORR for R/R CLL subjects [2 Years]
Endpoint/Outcome Measures: The proportion of subjects who achieve a PR or better at any time point while on study, as assessed by iwCLL Response Criteria
