determination of maximum tolerated dose (MTD) and recommended Phase 2 dose for patients with UGT1A1*28 genotype (wt/wt and wt/*28)

Study Overview

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.

  • •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
  • •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.

Outcomes

Primary Outcomes

determination of maximum tolerated dose (MTD) and recommended Phase 2 dose for patients with UGT1A1*28 genotype (wt/wt and wt/*28)

Incidence of dose-limiting toxicity within 28 days of treatment administration for patients with UGT1A1*28 genotype (wt/wt and wt/*28)

Secondary Outcomes

  • Tumor shrinkage per Response Evaluation Criteria in Solid Tumors (RECIST) every 8 weeks/2 cycles while receiving study drug for patients with UGT1A1*28 genotype (wt/wt and wt/*28)
  • limited pharmacokinetics (PK) for patients with UGT1A1*28 genotype (wt/wt and wt/*28)
  • limited incidence and severity of adverse events (AEs) and PK for UGT1A1 homozygous (*28/*28) patients
