Molecularly Targeted Theranostic Approach for the Detection and Treatment of Metastatic Carcinomas

Inclusion Criteria13

• Ability to understand and willingness to sign a written informed consent document.
• Age 18 or more years
• Pathologically confirmed GU, GI, GYN breast, cervical, uterine, or head and neck cancers with metastatic disease and measurable disease per RECIST (version 1.1) (i.e. at least 1 lesion > 1 cm or lymph node > 1.5 cm in short axis)
• Participant must have documented tumor progression for metastatic disease during or following at least one prior FDA approved systemic regimen (Androgen Deprivation allowed) as established by diagnostic imaging.
• Available archival tumor tissue (excisional, core, or FNA is acceptable). Tissue from a metastatic site is preferred when available.
• Eastern Cooperative Oncology Group Performance Status ≤ 2
• Participant must have completed prior systemic therapy at least 2 weeks (washout period) prior to \[68Ga\]Ga DOTA-5G PET scan. Any clinically significant toxicity (with the exceptions of hair loss and sensory neuropathy) related to prior therapy resolved to Grade 1 or baseline.
• Hematologic parameters defined as:
• Absolute neutrophil count (ANC) ≥ 1000 cells/mm3 Platelet count ≥ 100,000/mm3 Hemoglobin ≥ 8 g/dL
• Blood chemistry levels defined as:
• AST, ALT, alkaline phosphatase ≤ 5 times upper limit of normal (ULN) Total bilirubin ≤ 2 times ULN Creatinine ≤ 2 times ULN 10. Anticipated life expectancy ≥ 3 months 11. Able to remain motionless for up to 30-60 minutes per scan
• Completion of entry into \[68Ga\]Ga DOTA-5G PET study and completion of scan
• The presence of at least one measurable disease by \[68Ga\]Ga DOTA-5G PET/CT (SUVmax>2-fold above normal bone, brain, lung or liver and identified on standard of care diagnostic imaging)
