11 Long-Term Follow-Up from the OMNIVORE Trial: Response-Adaptive Nivolumab and Ipilimumab in Advanced Renal Cell Carcinoma (NCT03652142)

Abstract Background Immune checkpoint inhibitor-based combinations represent the standard of care for advanced renal cell carcinoma (RCC). The OMNIVORE trial (NCT03652142) investigated a response-adaptive strategy including treatment discontinuation in early nivolumab responders (Arm A) and salvage ipilimumab addition...

70 Lymphocyte Hsp70 is a Novel Predictive Biomarker for Response to Immune Checkpoint Inhibitors in Metastatic Renal Cell Carcinoma

A scRNA-seq atlas of tumors from metastatic RCC found a novel factor, Hsp70, that in lymphocytes strongly predicts response and greatly extended PFS after ICI, indicating that Hsp70 expression in lymphocytes predicts response to ICI across timepoints and cohorts.

Panitumumab-Based EGFR Blockade in SMARCB1-Deficient Renal Medullary Carcinoma: Preclinical Basis and Prospective Clinical Activity

Purpose: SMARCB1-deficient renal medullary carcinoma (RMC) is an ultra-rare, lethal malignancy refractory to therapies approved for other renal cell carcinomas, and its rarity makes randomized trials logistically unfeasible. We investigated whether wild-type epidermal growth factor receptor (EGFR) is a therapeutically...

74 HIF2α Downregulation and Clinical Outcomes in Patients with Clear Cell Renal Cell Carcinoma with and without Sarcomatoid Differentiation

Abstract Background Clear cell renal cell carcinoma (ccRCC) with sarcomatoid differentiation (sRCC) is associated with poor survival. Recent studies have shown downregulation of hypoxia-related pathways in sRCC (Motzer et al., Cancer Cell, 2020; El Zarif, Semaan et al., Cell Reports, 2024). In this study, we sought to...

8 Single Cell Transcriptomic Investigation of Renal Cell Carcinoma (RCC) Reveals Tissue Resident Memory Exhausted CD8+ T Cell Signature Associated with Resistance to Immune Checkpoint Inhibition (ICI)

A tissue residency gene program in Tex cells associated with non-response to immunotherapy was identified and nominates resident memory exhausted CD8+ T cells as a targetable subset of cells to improve CD8+ T cell-mediated anti-tumor immunity.

51 Discovery of Exhausted CD8+ T-cell States Associated with Clinical Outcomes in Renal Cell Carcinoma

It is found that baseline tumor infiltration by exhausted T cells with a resident memory phenotype (Tex-rm) is significantly associated with worse PFS in advanced RCC patients receiving ICI monotherapy or ICI+TKI combination therapy.
