Study to Determine the Maximum Tolerated Dose of the PARP Inhibitor CEP-9722 in Participants With Solid Tumors
January 23, 2024 updated by: Teva Branded Pharmaceutical Products R&D, Inc.
An Open-Label Study to Determine the Maximum Tolerated Dose of the PARP Inhibitor CEP-9722 When Administered as a Single Agent in Patients With Advanced or Metastatic Solid Tumors
CEP-9722 is an inhibitor of poly-adenosine diphosphate (ADP) ribose polymerase -1 and -2 (PARP).
The primary purpose of this study is to (Part 1) determine the maximum tolerated dose (MTD) of CEP-9722 administered daily to participants with advanced or metastatic solid tumors, (Part 2) to evaluate the safety and tolerability of that dose, and to investigate whether CEP-9722 has antitumor activity as a single agent.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Part 1: Maximum Tolerated Dose (MTD) of Oral CEP-9722
Time Frame: Cycle 1 (28 days)
|
MTD was defined as the highest dose level with 0 or 1 participant experiencing a dose-limiting toxicity (DLT) during cycle 1.
DLT was defined as any adverse event (AE) that was considered by the investigator as related or potentially related to CEP-9722 as follows: 1) hematologic: grade 4 hematologic adverse events, grade 3 or greater febrile neutropenia, grade 3 thrombocytopenia lasting 7 days or more, grade 3 thrombocytopenia with bleeding; 2) nonhematologic: grade 3 or 4 nonhematologic AEs; grade 4 vomiting or diarrhea; grade 3 nausea, vomiting, or diarrhea that persisted for 48 hours or more despite optimal medical intervention; QTcF (QTc by Fridericia's cube root formula) greater than 500 milliseconds (msec) (confirmed by a repeat measurement on the same visit).
During Cycle 1 of Part 1, any toxicity possibly related to treatment with CEP-9722 that caused a cumulative interruption of dosing for 7 or more days was considered dose limiting.
|
Cycle 1 (28 days)
|
Part 2: Number of Participants With Adverse Events
Time Frame: Up to 8 months
|
An AE was defined as any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship.
SAEs were defined as death, a life-threatening AE, inpatient hospitalization or prolongation of existing hospitalization, persistent or significant disability or incapacity, a congenital anomaly or birth defect, or an important medical event that jeopardized participant and required medical intervention to prevent 1 of the outcomes listed in this definition.
A summary of other non-serious AEs and all serious AEs, regardless of causality is located in Reported AE section.

|
Predose (0 hour), 2 and 6 hours postdose on Days 1 and 15 of Cycle 1
|
|
Part 1: Overall Response Rate (ORR) - Percentage of Participants With the Best Tumor Response
Time Frame: From the start of the treatment until disease progression/recurrence (up to 168 days)
|
ORR was assessed by the best tumor response (complete response [CR], partial response [PR], stable disease [SD], and progressive disease [PD]) during the study using Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST 1.1).
CR: Disappearance of all target and non-target lesions.
PR: At least a 30% decrease in the sum of the longest diameter (LD) of target lesions, taking as reference the baseline sum.
SD: neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum LD since the treatment started.
PD: At least a 20% increase in the sum of the LD of target lesions, taking as reference the smallest sum LD recorded since the treatment started or the appearance of 1 or more new lesions and/or unequivocal progression of existing nontarget lesions.
