This phase I trial studies the best dose and side effects of tazemetostat in treating patients with solid tumors or B-cell lymphomas with liver dysfunction that have spread to other places in the body or cannot be removed by surgery. Tazemetostat may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.
Name: Laboratory Biomarker Analysis
Name: Pharmacological Study
Name: Tazemetostat
Description: Frequency and severity of adverse events will be tabulated using counts and proportions detailing frequently occurring, serious and severe events of interest. Adverse events will be summarized using all adverse events experienced, although a sub-analysis may be conducted including only those adverse events in which the treating physician deems possibly, probably or definitely attributable to study treatment.
Measure: Incidence of adverse events of tazemetostat in patients with varying degrees of hepatic dysfunction assessed using Common Terminology Criteria for Adverse Events version 5.0 Time: Up to 2 yearsDescription: RP2D will be determined.
Measure: Recommended phase 2 dose (RP2D) of tazemetostat in patients with varying degrees of hepatic dysfunction Time: Up to 2 yearsDescription: Plasma concentrations will be measured by Q2 Solutions using a validated Liquid chromatography (LC)/mass spectrometry (MS)/MS assay. Molecular and clinical predictors of clinical outcomes will be investigated using logistic regression and Cox proportional hazards models. Potential predictors include clinical predictors and molecular correlates. Descriptive statistics and plotting of data will also be used to better understand potential relationships. Given the small sample size, and exploratory nature of these endpoints, all pharmacodynamic analyses conducted will be considered exploratory. All analyses will be considered exploratory and inference will be performed with appropriate caution.
Measure: Pharmacokinetic (PK) profiles of tazemetostat in patients with varying degrees of hepatic dysfunction Time: Up to course 4 day 1 (day 85)Description: Molecular and clinical predictors of clinical outcomes will be investigated using logistic regression and Cox proportional hazards models. Potential predictors include clinical predictors and molecular correlates. Descriptive statistics and plotting of data will also be used to better understand potential relationships. All analyses will be considered exploratory and inference will be performed with appropriate caution.
Measure: Antitumor activity of tazemetostat Time: Up to 2 yearsDescription: Molecular and clinical predictors of clinical outcomes will be investigated using logistic regression and Cox proportional hazards models. Potential predictors include clinical predictors and molecular correlates. Descriptive statistics and plotting of data will also be used to better understand potential relationships. All analyses will be considered exploratory and inference will be performed with appropriate caution.
Measure: Antitumor activity of tazemetostat in population with tumors with aberrations in EZH2 or SWI/SNF complex pathways Time: Up to 2 yearsDescription: Response will be assessed using the Response Evaluation Criteria in Solid Tumors (RECIST) criteria 1.1
Measure: Objective confirmed response Time: Up to 2 yearsDescription: Response will be assessed using the RECIST criteria 1.1.
Measure: Duration of response Time: Up to 2 yearsDescription: Response will be assessed using the RECIST criteria 1.1.
Measure: Best response Time: Up to 2 yearsAllocation: N/A
