Badanie doustnego stosowania tazemetostatu u pacjentów z umiarkowanymi i ciężkimi zaburzeniami czynności wątroby z zaawansowanymi nowotworami

12 listopada 2026 zaktualizowane przez: Epizyme, Inc.

Otwarte badanie fazy I dotyczące farmakokinetyki i bezpieczeństwa wielodawkowego tazemetostatu doustnego u pacjentów z umiarkowanymi i ciężkimi zaburzeniami czynności wątroby i zaawansowanymi nowotworami

This main aim of this trial will be to study the blood levels (known as pharmacokinetics) of the study drug tazemetostat.

The pharmacokinetics of the study drug in participants with advanced solid tumors and moderate or severe hepatic (liver) impairment will be compared with participants with advanced malignancies and normal hepatic function.

An advanced malignancy is a cancer that has recurred (come back) after prior treatment or hasn't controlled with treatment.

The trial will also study the safety of the study drug in participants (how well it is tolerated).

Szczegółowy opis

The study will be conducted in 2 parts for subjects with advanced malignancies and either normal liver function, or advanced malignancies and moderate, or severe hepatic impairment. Subjects in Part 1 of the study will receive a single oral, 800 mg dose of tazemetostat on Day 1 and Day 15. In addition, the subjects will receive tazemetostat (oral 800 mg dose) tablets to be taken twice daily from Day 5 to Day 14. Blood samples for PK analysis will be obtained on Day 1 through Day 4 and again on Day 15 through Day 18. Part 1 ends on Day 18.

Subjects continuing treatment in Part 2 will receive tazemetostat (oral 800 mg dose) tablets to be taken twice daily in repeated 28-day cycles beginning on Day 19 until Investigator-assessed clinical progression per standard practice, or unacceptable toxicity, or until another discontinuation criterion is met. Subjects must have an end of study visit for safety assessment 30 days after the last dose of tazemetostat or prior to initiation of a subsequent anticancer therapy, whichever occurs first. Supplementary study conduct information not mandated to be present in this protocol is provided in the accompanying procedure manuals (i.e., laboratory, pharmacy, ECG manuals). Such manuals will provide the site personnel with administrative and detailed technical information that does not impact subject safety.

Parts 1 and 2: Number of Participants With Treatment-Emergent Adverse Events (TEAEs) and Treatment-Emergent Serious Adverse Events (TESAEs)
Ramy czasowe: From first dose of study drug (Day 1) up to 30 days after last dose of study drug, approximately 78 weeks

An adverse event (AE) was any untoward medical occurrence in a participant or clinical investigation participant administered a medicinal product and which did not necessarily have a causal relationship with this study drug. A serious AE was an AE that occurred during any study phase (i.e., baseline, treatment, washout, or follow-up), and at any dose of the study drug, comparator, or placebo, that fulfilled one or more of the following: resulted in death, was life-threatening, required hospitalization or prolongation of existing hospitalization, resulted in disability or incapacity, was a congenital abnormality or birth defect or was an important medical event that jeopardized the participant or required medical intervention to prevent one of the outcomes listed above. TEAEs were AEs that started or worsened in severity on or after the day of the first dose of study drug through 30 days after the end of study drug.

From first dose of study drug (Day 1) up to 30 days after last dose of study drug, approximately 78 weeks
