Brief summary
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.
Detailed description
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
Interventions
Pentixather radiolabeled with 212-lead to target malignant cells with the CXCR4 ligand.
Pentixather radiolabeled with 203-Lead to identify the CXCR4 ligand on the malignant lesions for dosimetric analysis and treatment planning.

Eligibility
Inclusion criteria
* 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
Exclusion criteria
* 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
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Determine the recommended phase 2 dose of 212-Lead Pentixather | 3 months | The recommended phase 2 dose is based on the number of dose limiting toxicities observed post-treatment. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Determine the targeting of atypical pulmonary neuroendocrine tumor and/or neuroendocrine carcinoma lesions with 203-Lead Pentixather SPECT/CT | baseline | The number of lesions identified with 203-Lead Pentixather SPECT/CT will compared to FDG PET/CT and diagnostic CT scans at baseline. |
| Determine tumor response | 3 months | Tumor response will be assessed using the Response Evaluation Criteria in Solid Tumours (RECIST, v 1.1). |
