Prospective Feasibility Pilot Study Evaluating the Value of [68Ga]Ga-PENTIXAFOR PET-CT in Patients With Metastatic Small Cell Lung Cancer (SCLC) at Diagnosis and Disease Progression
[68Ga]Ga-PentixaFor PET-CT will be performed in patients with Small cell lung cancer (SCLC) to confirm the targeting of CXCR4 by [68Ga]Ga-PentixaFor
Small cell lung cancer (SCLC) accounts for approximately 15% of lung cancers, but remains a cancer with a poor prognosis, often detected at a metastatic stage and associated with a high rate of early recurrence.
Therapeutic options for unresectable SCLC are limited and essentially rely on first-line radiochemotherapy for limited disease or chemo-immunotherapy, possibly supplemented by radiotherapy, for extensive disease.
CXCR4 is a chemokine receptor that is highly expressed in this cancer. By targeting CXCR4 with [177Lu]Lu-PentixaTher or [90Y]Y-PentixaTher, patients with SCLC could benefit from a new type of treatment in this indication: Peptide Receptor Radionuclide Therapy (PRRT).
However, there is a need for a preliminary diagnostic study due to a lack of published data.
[68Ga]Ga-PentixaFor is an experimental compound that binds with high affinity to CXCR4 and appears to be a promising candidate for PET-CT imaging of SCLC. This initial step is crucial to confirm CXCR4 targeting by [68Ga]Ga-PentixaFor before considering PRRT with therapeutic radionuclides such as Lu-177 or Y-90 in future trials.
