Extended Use Protocol for Participants With Cancer to Receive Continued Treatment With CS-7017

Study Overview
=================
Brief Summary
-----------------
This is a study of CS-7017 designed to allow participants who completed participation in a clinical study of CS-7017 without experiencing disease progression or unacceptable toxicity to continue treatment with study drug. Participants who have not progressed while receiving CS-7017 will continue to benefit from longer administration of the agent.

Detailed Description
-----------------
This is an open-label non-randomized study of CS-7017 designed to allow participants who completed participation in a clinical study of CS-7017 without experiencing disease progression or unacceptable toxicity to continue treatment with study drug.

Participation Criteria

Eligibility Criteria
-----------------
Inclusion Criteria: Participant previously treated with CS-7017 as part of a study that included CS-7017 and has shown clinical benefits from treatment with CS-7017. Exclusion Criteria: Anticipation of need for a major surgical procedure or radiation therapy during the study. Any of the following conditions within 6 months prior to initiating study treatment: Myocardial infarction with significant impairment of cardiac function (eg, ejection fraction ≤ 50%), severe/unstable angina pectoris, coronary/peripheral artery bypass graft, New York Heart Association (NYHA) class II or higher congestive heart failure. Participants with clinically significant pleural or pericardial effusions. Clinically significant active infection, which requires antibiotic therapy, or human immune deficiency virus (HIV)-positive subjects receiving antiretroviral therapy. Participants with diabetes mellitus requiring treatment with insulin, sulfonylureas or thiazolidinediones (TZDs) agents, malabsorption syndrome, chronic diarrhea, inflammatory bowel disease, or partial bowel obstruction.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Best Response Following Extended Use of CS-7017 Upon Completion of Participation in a Clinical Study of CS-7017 in Participants With Cancer | 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). | From baseline and every 6 weeks postdose, up to 2 years 6 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Response/Stable Disease Duration and Time to Progression Following Extended Use of CS-7017 Upon Completion of Participation in a Clinical Study of CS-7017 in Participants With Cancer | 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. | Baseline and every 6 weeks postdose, up to 2 years 6 months | 
| Treatment-Emergent Adverse Events Occurring in Participants Following Extended Use of CS-7017 Upon Completion of Participation in a Clinical Study of CS-7017 in Participants With Cancer | 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. | Baseline up to 30 days after last dose, up to 2 years 6 months |
