Trial Outcomes & Findings for Extended Use Protocol for Participants With Cancer to Receive Continued Treatment With CS-7017 (NCT NCT00881569)

NCT ID: NCT00881569

Last Updated: 2020-09-28

Results Overview

At each evaluation, the participant's status was assessed as complete response (CR), partial response (PR), stable disease (SD), or progressive disease (PD); the best response was then identified. CR was defined as a disappearance of all target lesions, PR was defined as at least a 30% decrease in the sum of diameters of target lesions, and stable disease (SD) was defined as neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease (PD; at least a 20% increase in the sum of diameters of target lesions).

Participant Flow

A total of 2 participants who met all inclusion and no exclusion criteria were enrolled in this extension study at 1 clinic site in the United States.

This extension study was designed to allow continuation of treatment in participants who demonstrated clinical benefit from previous treatment with CS-7017 in CS7017-A-U102 study.

PRIMARY outcome

Timeframe: From baseline and every 6 weeks postdose, up to 2 years 6 months

Population: Best response was assessed in All Enrolled Participants.

At each evaluation, the participant's status was assessed as complete response (CR), partial response (PR), stable disease (SD), or progressive disease (PD); the best response was then identified. CR was defined as a disappearance of all target lesions, PR was defined as at least a 30% decrease in the sum of diameters of target lesions, and stable disease (SD) was defined as neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease (PD; at least a 20% increase in the sum of diameters of target lesions).

SECONDARY outcome

Timeframe: Baseline and every 6 weeks postdose, up to 2 years 6 months

Population: Duration of response/stable disease and time to progression were assessed in All Enrolled Participants.

Duration of response was to be calculated as the date of progression minus the earliest date of complete response (CR) or partial response (PR), plus 1. The earliest date of CR or PR was to be taken from the earlier study (CS7017-A-U102). If any participant entered the study with stable disease (SD), then the duration of SD was to be calculated as the date of progression minus the date of first dose, plus 1. Time to progression was to be calculated as the date of progression minus the date of first dose of study medication in the earlier study, plus 1.

SECONDARY outcome

Timeframe: Baseline up to 30 days after last dose, up to 2 years 6 months

Population: Safety events were assessed in the Safety Population.

Adverse events (AEs) were graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) version 3.0. AE intensity was assessed according to the following scale: Mild (Grade 1), Awareness of sign or symptom, but easily tolerated, ie, does not interfere with subject's usual function; Moderate (Grade 2), Discomfort enough to cause interference with usual activity; Severe (Grade 3), Incapacitating with inability to work or do usual activity, ie, interferes significantly with participant's usual function. Severe (Grade 3) AEs indicate worse outcomes.
