Biomarkers for Neoadjuvant Pembrolizumab in Non-Metastatic Prostate Cancer Positive by 18FDG-PET Scanning (NCT04009967)
Phase II Clinical and Translational Study of Neoadjuvant Pembrolizumab Before Radical Prostatectomy in Non-metastatic Gleason ≥8 Prostate Cancer Patients Positive by 18FDG-PET Scanning ( PICT-01)
🩺 Plain-English Summary (8th-Grade Level)
Various approaches are currently being developed for prostate cancer immunotherapy. However, a major challenge facing the development of cancer immunotherapy is the identification of tumors that would best respond to this type of treatment. Different studies suggest that prostate cancer more likely to progress are more infiltrated by exhausted T cells expressing the cell surface protein PD1 (Programmed cell death 1). Therefore, there is a strong rationale for selecting patients at higher risk of progression for testing the efficacy of anti-PD1 therapy. High glucose metabolism as detected by fludeoxyglucose F18 (FDG)-positron emission tomography (PET) (18FDG-PET) imagery is an innovative biological biomarker-based method to identify patients at higher risk of recurrence and early failure to hormonotherapy. Recent study demonstrated that high intra-prostatic 18-FDG-uptake was associated with higher Gleason grades. Therefore the one third of Gleason ≥ 8 prostate cancer patients with higher 18FDG uptake would be ideal candidates for early immunotherapy treatments based on anti-PD-1 such as pembrolizumab. The study aimed to identify biomarkers predictive the response to Pembrolizumab given prior to radical prostatectomy in participants with primary prostate cancer at high risk of progression.
