研究概览

简要总结

This is a first-in-human clinical trial evaluating the safety of an alpha-radiation treatment (Lead-212 labelled Pentixather) in patients who have been diagnosed with, and previously treated, for atypical carcinoid lesions of the lung.

详细描述

This is a study to determine what dose is acceptably safe for further testing.

In this study, participants are asked to:

  • undergo SPECT/CT imaging with Lead-203 Pentixather (a radiotracer) to ensure the tumor lesions have the needed receptors
  • undergo serial blood sampling for during and after the SPECT/CT scan for radiation and dosimetry calculations (to determine how much of the Lead-212 Pentixather to administer)
  • receive up to 2 infusions of arginine & lysine as a kidney protectant
  • receive up to 2 infusions of Lead-212 Pentixather, 6 weeks between each infusion
  • undergo imaging at 3 months post treatment to determine disease response

入选标准

  • ability to provide independent consent
  • adequate bone marrow function (platelet count ≥ 100,000; hemoglobin of ≥ 10 g/dL; neutrophil count ≥ 1,500 cells/mm3)
  • adequate kidney function (creatinine clearance of ≥ 50 mL/min using the Cockcroft-Gault equation
  • adequate liver function (serum bilirubin ≤ 3x the upper limit of normal, AST ≤ 5x the upper limit of normal, and ALT ≤ 5x the upper limit of normal)
  • failed initial therapy or declined further therapy known to confer benefit
  • have at least one lesion ≥ 2 cm that is positive for CXCR4 as demonstrated by Lead-203 Pentixather SPECT/CT

排除标准

  • major surgery within 4 weeks of consent
  • antoher investigational agent within 4 weeks of consent
  • uncontrolled illness including, but not limited to, ongoing or active infection that would necessitate a delay in therapy or cause a hospital admission, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, hepatic cirrhosis or severe impairment, or psychiatric illness/social situations that would limit compliance with study requirements.
  • prior solid organ transplant
  • cytotoxic or antineoplastic therapy within 21 days of consent (42 days for nitrosoureas)
  • antibody therapy within the 21 days of consent
  • allogenic bone marrow or stem cell transplant, or any stem cell infusion, within 84 days of consent
  • pregnancy
  • breastfeeding
  • refusal to comply with birth control requirements during study

研究组 & 干预措施

212-Lead Pentixather

Experimental

Single intravenous infusion of Pentixather radiolabeled with Lead-212. Administered activity to participant is calculated from bone marrow and renal radiation constraints.

Treatment is administered in 2 cycles with 6 weeks between the cycles.

干预措施: 203-Lead Pentixather SPECT/CT (Diagnostic Test)

结局指标

主要结局

Determine the recommended phase 2 dose of 212-Lead Pentixather

时间窗: 3 months

The recommended phase 2 dose is based on the number of dose limiting toxicities observed post-treatment.

次要结局

  • Determine the targeting of atypical pulmonary neuroendocrine tumor and/or neuroendocrine carcinoma lesions with 203-Lead Pentixather SPECT/CT(baseline)
  • Determine tumor response(3 months)
