Patient case: 47-year-old male with melanoma; genetic feature: APC loss of function

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

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.

Eligibility: Inclusion Criteria:
  1. Histologically confirmed malignant solid tumor and not a candidate for known regimens or protocol treatments of higher efficacy or priority
  2. Failed conventional therapy for their cancer or have a malignancy for which a conventional therapy does not exist
  3. Recovered from all acute adverse effects of prior therapies, excluding alopecia (hair loss)
  4. ECOG performance status of 0, 1, or 2
  5. 18 years of age or older
  6. Normal organ and bone marrow function as defined by:
  -  absolute neutrophil count greater than or equal to 1,500 cells/microliter
  -  platelets greater than or equal to 100,000 cells/microliter
  -  total bilirubin within normal institutional limits
  -  AST (SGOT)/ALT (SGPT) less than or equal to 2.5 x institutional upper limit of normal (ULN) or less than or equal to 5.0 x ULN in patients with liver metastases
  -  plasma creatinine less than or equal to 1.5 x institutional ULN OR
  -  creatinine clearance greater than or equal to 60 mL/min/1.73 m2 for patients with creatinine levels above institutional normal
  7. Ability to understand and the willingness to sign a written informed consent document
  Exclusion Criteria:
  1. Previously treated with irinotecan, or had chemotherapy or radiotherapy within 4 weeks (6 weeks for nitrosoureas or mitomycin C) prior to entering the study, or not recovered from adverse effects due to agents administered more than 4 weeks earlier
  2. Receiving any other investigational agent
  3. Known brain metastases
  4. History of allergic reactions attributed to compounds of similar chemical composition to IHL-305
  5. Concurrent serious infections (i.e., requiring an intravenous antibiotic)
  6. Pregnant women or women of childbearing potential and not using methods to avoid pregnancy; a negative pregnancy test (urine or serum) must be documented at baseline for women of childbearing potential; no breast-feeding while on study.
  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.
  9. History of serious ventricular arrhythmia (ventricular tachycardia [VT] or ventricular fibrillation [VF], greater than or equal to 3 beats in a row); QTc greater than or equal to 450 msec for men and 470 msec for women; or left ventricular ejection fraction (LVEF) less than or equal to 40% by multi-gated acquisition scan (MUGA).
