ASCO GU 2018: Erdafitinib, a Pan-fibroblast Growth Factor Receptor Inhibitor, in Patients with Metastatic or Unresectable Urothelial Carcinoma and FGFR Alterations

San Francisco, CA ( Although immune checkpoint inhibitors (ICI) have improved outcomes in some patients with platinum-resistant metastatic or unresectable urothelial carcinoma (mUC), many patients (eg, patients with TCGA luminal 1 tumors, many of whom are FGFR alterations (FGFRa)) may not benefit. Erdafitinib (ERDA; JNJ-42756493), a pan-fibroblast growth factor receptor (pan-FGFR) (1-4) inhibitor, demonstrated promising phase 1 activity: 11 partial responses among 24 FGFRa mUC pts. We report efficacy and safety of ERDA in the ongoing global open-label phase 2 study BLC2001 (NCT02365597).

ASCO GU 2018: Phase II Trial of 6 Months ADT/Abiraterone Acetate Plus Prednisone and Definitive Radiotherapy - Intermediate to High Risk Localized Prostate Cancer - AbiRT Trial

San Francisco, CA ( Combined external beam radiotherapy (RT) and androgen deprivation therapy (ADT) improves survival over RT alone for high risk prostate cancer (PC). Long-term ADT use, currently recommended for high risk PC, also increases toxicity. Recent data suggests synergistic efficacy with the addition of abiraterone acetate plus prednisone (AAP) to RT/ADT. Potent androgen blockade may provide biochemical control with short-term ADT course in men with aggressive but localized PC.

ASCO GU 2018: Expression of Immune Checkpoints on Circulating Tumor Cells in Men with Metastatic Prostate Cancer 

San Francisco, CA ( Most immune checkpoint inhibitors have shown limited efficacy in unselected men with mPC, and there is limited understanding about which immune checkpoints (ICs) are relevant in mPC. We evaluated ICs on the cell surface of circulating tumor cells (CTCs) in patients with mPC.

ASCO GU 2018: Clinical Utility of Foundation One Tissue Molecular Profiling in Men with Metastatic Prostate Cancer

San Francisco, CA ( In the era of precision medicine, significant effort has been placed on identifying clinically actionable molecular targets to aid in the treatment of metastatic prostate cancer (mPC). Recent data supports homologous repair and mismatch repair deficiencies to guide the use of PARP inhibitors/platinum chemotherapy or pembrolizumab, respectively. We analyzed the clinical utility of Foundation One (FO) somatic genomic profiling in men with mPC.

ASCO GU 2018: Patterns of Progression in Bone and Soft Tissue Following Treatment with Ra-223 in Metastatic Castrate Resistant Prostate Cancer

San Francisco, CA ( Bone scans were not obtained in the phase 3 ALSYMPCA trial, and retrospective series have reported varying rates of development of new lesions and resolution of existing lesions, following treatment with Radium-223 (Ra-223).

ASCO GU 2018: The CLEAR study: A Phase 3 Trial to Compare Efficacy and Safety of Lenvatinib in Combination with Everolimus or Pembrolizumab Versus Sunitinib Alone in First-line Treatment of Patients with Metastatic Renal Cell Carcinoma

San Francisco, CA ( Lenvatinib (LEN) is a multikinase inhibitor of vascular endothelial growth factor (VEGF) receptor 1–3, fibroblast growth factor receptor 1–4, platelet-derived growth factor receptor alpha, and RET and KIT. Based on a phase 2 study,1 LEN was approved in combination with everolimus (EVE) for the treatment of metastatic renal cell carcinoma (RCC) following 1 prior VEGF-targeted therapy. A phase 1b/2 study of LEN in combination with pembrolizumab (PEM) in patients (pts) with RCC is also underway.

ASCO GU 2018: Self-reported Quality of Life as a Predictor of Survival in Renal Cell Carcinoma

San Francisco, CA ( While biomarkers for various malignancies continue to be developed, sometimes there can be no substitute for a physical and mental exam. Clinical evaluation of the patient may provide guidance into their cancer-related status and perhaps even serve as a biomarker.
