Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Early identification of tumor progression may reduce unnecessary therapy cycles and their associated risk of adverse events as well as reducing costs and improving patient care by initiating an earlier change in treatment towards a possibly more efficacious therapy.
Response Evaluation Criteria In PSMA-imaging (RECIP) version 1.0 is an evidence-based framework to evaluate therapeutic efficacy in metastatic prostate cancer using PSMA-imaging\[2,3\]. Interim PSMA-PET/CT by RECIP 1.0 criteria performed at 10 weeks after two cycles of PSMA theranostics (\[177Lu\]Lu-PSMA- 617 or \[177Lu\]Lu-PSMA-I\&T) is prognostic for overall survival\[2\]. RECIP 1.0 criteria were validated based on overall survival outcome for measuring response in metastatic prostate cancer during androgen receptor-signaling inhibitors\[4\], as well as in early-stage prostate cancer in patients with biochemical recurrence after initial therapy\[5\].
Lutetium-177 is a beta therapy that also emits 11% gamma rays, which can be utilised to derive whole-body tomographic images similar to PSMA-PET/CT. Serial Lutetium-177 PSMA-targeted single photon emission tomography/computed tomography \[177Lu\]Lu-PSMA-SPECT/CT henceforth referred to as LuPSMASPECT/ CT has potential as an imaging response biomarker for 177Lu-PSMA therapy. This principle enables image quantitation and evaluation after every treatment dose. SPECT/CT post \[177Lu\]Lu-PSMA administration represents a potentially cost-effective alternative to interim PSMA-PET/CT.
Preliminary results have shown a good correlation between changes in LuPSMASPECT/ CT during PSMA theranostics and clinical outcome. LuPSMA-SPECT/CT can provide effective response information as early as 6 weeks after initiation of \[177Lu\]Lu-PSMA-I\&T, i.e. any increase in total tumor volume on SPECT/CT imaging was associated with shorter PSA-PFS (median: 3.7 vs 6.7 months; HR, 2.5; 95% CI 1.5-4.2; p\<0.001)\[6\]. Changes in total tumor volume on 12-week LuPSMASPECT/ CT were also found to be correlated with progression-free survival after \[177Lu\]Lu-PSMA-I\&T\[7\].
The growing evidence suggesting that LuPSMA-SPECT/CT is a new, early surrogate marker for assessing response to treatment has several potential upsides, including the potential replacement of interim PSMA-PET/CT, therefore costsaving, radiation exposure-saving, and SPECT/CT imaging being more convenient and widely available.
Given that data regarding SPECT/CT-based treatment response monitoring during PSMA theranostics are limited, this study aims to prospectively investigate the role of LuPSMA-SPECT/CT imaging for response evaluation during treatment with \[177Lu\]Lu-PSMA in mCRPC patients.
