Safety Study of IHL-305 (Irinotecan Liposome Injection) to Treat Advanced Solid Tumors

Phase 1

Completed

• Conditions: Cancer

• Registration Number: NCT00364143
• Lead Sponsor: Yakult Honsha Co., LTD

Brief Summary

The purpose of this study is to determine whether IHL-305 (irinotecan liposome injection) is safe and effective in the treatment of advanced solid tumors.

Detailed Description

This is a Phase I dose-escalation study of intravenous administration of IHL-305 in patients with advanced solid tumors. Patients will receive IHL-305 as an intravenous infusion over 60 minutes on Day 1 followed by a 27-day observation period for a total of 28 days (4 weeks) per cycle. Two patient populations will be evaluated separately; patients with UGT1A1\*28 genotype homozygous wild-type (wt/wt) and heterozygous (wt/\*28) variants as one group, and patients with UGT1A1\*28 homozygous variant (\*28/\*28) as another group.

7. Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, unstable angina pectoris, or psychiatric illness/social situations that would limit compliance with study requirements
8. Significant cardiac disease including heart failure that meets New York Heart Association (NYHA) class III and IV definitions; history of myocardial infarction within one year of study entry; uncontrolled dysrhythmias; or poorly controlled angina.
