Zr89 + PET Companion Trial

Prior treatment

• Females who report they are pregnant or breast-feeding at the time of screening will not be eligible for this study. Female participants of child-bearing potential will have a urine pregnancy test prior to infusion of the study radiotracer to confirm they are not pregnant.

Other illness

• Patients who have any splenic disorders, or had splenectomy, that in the opinion of an investigator could compromise protocol objectives.
• Serious or unstable medical or psychological conditions that, in the opinion of the investigator would compromise the subject's safety or successful participation in the study.

Other

• Inability to tolerate imaging procedures in the opinion of the investigator or treating physician.
• Ineligible for the LIMIT Melanoma Trial.

• Adult patients, at least 18 years of age
• History of histologically confirmed melanoma as assessed per medical record review.
• At least one site of measurable disease (per RECIST 1.1) that is seen on CT, MRI, or FDG PET/CT.
• Potentially eligible to participate in the LIMIT Melanoma Trial.
• Patients must have adequate baseline organ function as determined per LIMIT Melanoma Trial (IRB 835033) (these tests will be completed as part of LIMIT trial screening and will not be repeated for the imaging companion study)
  • Adequate organ function: per LIMIT Melanoma Trial (IRB 35033)
  • System Laboratory Values Hematologic Absolute Neutrophil Count (ANC) ≥ 1.0 x 109/L Hemoglobin ≥ 9 g/dL Platelet Count ≥ 100 x 109/L PT/INRa and PTT ≤ 1.3 x ULN Hepatic Total Bilirubinb ≤ 1.5 x ULN AST and ALT ≤ 2.5 x ULN Renal Serum Creatinine ≤ 1.5 mg/dL Abbreviations: ALT = alanine transaminase; ANC = absolute neutrophil count; AST = aspartate aminotransferase; INR = international normalized ratio; LLN = lower limit of normal; PT = prothrombin time; PTT = partial thromboplastin time; ULN = upper limit of normal.
  • a Subjects receiving anticoagulation treatment may be allowed to participate with INR established within the therapeutic range prior to enrollment.
  • b Subjects with known Gilbert's syndrome must have a total bilirubin \< 3.0 x ULN).
  • c If serum creatinine is \> 1.5 mg/dL, calculate creatinine clearance using standard Cockcroft-Gault formula. Creatinine clearance must be ≥ 50 mL/min to be eligible.
• Participants must be informed of the investigational nature of this study and provide written informed consent in accordance with institutional and federal guidelines prior to study-specific procedures.
