Bempegaldesleukin plus nivolumab in first-line advanced/metastatic urothelial carcinoma: Results from a phase II single-arm study (PIVOT-10).

Background: In PIVOT-02, bempegaldesleukin (BEMPEG), a pegylated interleukin-2 cytokine prodrug, in combination with nivolumab (NIVO), a Programmed cell death protein 1 inhibitor, demonstrated the potential to provide additional benefits over immune checkpoint inhibitor monotherapy in patients with urothelial carcinoma, warranting further investigation. We evaluated BEMPEG plus NIVO in cisplatin-ineligible patients with previously untreated locally advanced or metastatic urothelial carcinoma.

Methods: This open-label, multicenter, single-arm, phase II study enrolled patients with locally advanced/surgically unresectable or metastatic urothelial carcinoma and who were ineligible for cisplatin-based treatment.

Efficacy and safety of pembrolizumab in patients with advanced urothelial carcinoma deemed potentially ineligible for platinum-containing chemotherapy: Post hoc analysis of KEYNOTE-052 and LEAP-011.

Background: First-line pembrolizumab monotherapy is a standard of care for platinum-ineligible patients with advanced urothelial carcinoma (UC). No global standardized definition of platinum ineligibility exists. This study aimed to evaluate the efficacy and safety of pembrolizumab monotherapy in patients with UC who met various criteria for platinum ineligibility.

A Pilot Study of the CD38 Antagonist Daratumumab in Patients with Metastatic Renal Cell Carcinoma or Muscle-Invasive Bladder Cancer.

Prognostic Value of Fibroblast Growth Factor Receptor Genetic Alterations in Metastatic Urothelial Carcinoma.

Introduction: Evidence is limited on whether fibroblast growth factor receptor gene alterations (FGFRalt) impact clinical outcomes in patients with locally advanced or metastatic urothelial cancer (mUC). This study evaluated progression-free survival (PFS) in patients with mUC based on FGFRalt status in the first-line setting (1L).

Patients And Methods: Data on mUC patients were retrieved via convenience sampling of oncologists/urologists surveyed between August and September 2020 who treated at least 1 FGFRalt patient between July 2017 and June 2019.

A Phase 2 Study of Sitravatinib in Combination with Nivolumab in Patients with Advanced or Metastatic Urothelial Carcinoma.

Background And Objective: Checkpoint inhibitor therapy (CPI) has demonstrated survival benefits in urothelial carcinoma (UC); however, not all patients benefit from CPI due to resistance. Combining sitravatinib, a multitargeted receptor tyrosine kinase inhibitor of TYRO3, AXL, and MERTK (TAM) receptors and VEGFR2, with CPI may improve antitumor responses. Our objective was to assess the efficacy and safety of sitravatinib plus nivolumab in patients with advanced/metastatic UC.

Long-Term Oncological Outcomes in Patients Diagnosed With Nonmetastatic Plasmacytoid Variant of Bladder Cancer: A 20-Year University of Texas MD Anderson Cancer Center Experience.

Purpose: The treated natural history of nonmetastatic plasmacytoid variant of bladder cancer (PV-BCa) is poorly understood owing to its rarity. We sought to examine the disease recurrence and metastasis patterns in this select group of patients in order to identify opportunities for intervention.

Materials And Methods: We conducted a natural language processing algorithm-augmented retrospective chart review of 56 consecutive patients who were treated with curative intent for nonmetastatic PV-BCa at our institution between 1998 and 2018.

Plain language summary of erdafitinib in locally advanced or metastatic urothelial carcinoma: a phase 2 study with long-term follow-up.

What Is This Summary About?: This is a plain language summary of two articles describing the results from a study called BLC2001. The study examined the effect of a medication called erdafitinib on participants with a type of cancer known as urothelial carcinoma that had either spread beyond the bladder or urinary tract into surrounding organs and/or nearby muscles (locally advanced) and was not removable by surgery (unresectable) or had spread to other parts of the body (metastatic). In this study, researchers wanted to learn if erdafitinib was safe and effective at stopping or reducing tumor growth in participants with locally advanced and unresectable or metastatic urothelial carcinoma with certain genetic alterations (changes in DNA sequence) in two related genes called fibroblast growth factor receptor 2 () and 3 ().

Erdafitinib or Chemotherapy in Advanced or Metastatic Urothelial Carcinoma.

Background: Erdafitinib is a pan-fibroblast growth factor receptor (FGFR) inhibitor approved for the treatment of locally advanced or metastatic urothelial carcinoma in adults with susceptible alterations who have progression after platinum-containing chemotherapy. The effects of erdafitinib in patients with -altered metastatic urothelial carcinoma who have progression during or after treatment with checkpoint inhibitors (anti-programmed cell death protein 1 [PD-1] or anti-programmed death ligand 1 [PD-L1] agents) are unclear.

Methods: We conducted a global phase 3 trial of erdafitinib as compared with chemotherapy in patients with metastatic urothelial carcinoma with susceptible alterations who had progression after one or two previous treatments that included an anti-PD-1 or anti-PD-L1.

Objective: To analyze the outcomes of patients with mUC and any (mutations or fusions) who received anti-PD-(L)1 therapy.

Design Setting And Participants: In this noninterventional, retrospective, multicenter study, clinical practice data were collected from - patients who received prior immunotherapy between May 2018 and July 2019.

Outcome Measurements And Statistical Analysis: Investigator‑determined overall response rate (ORR), disease control rate (DCR), and overall survival (OS) were assessed in multivariate and unadjusted analyses.

Targeting the FGFR Pathway in Urothelial Carcinoma: the Future Is Now.

As we come to better understand cancer genomics, we are increasingly shifting towards precision medicine. FGFR has been elucidated as one of the oncogenic driver pathways in urothelial carcinoma, leading to exciting targeted drug development. Although many agents are being investigated, erdafitinib is the only FGFR inhibitor currently approved by the FDA for treating platinum-refractory metastatic urothelial carcinoma harboring susceptible FGFR2/3 alterations, with seemingly higher response rates than second-line chemotherapy or immunotherapy.

Longitudinal GFR trends after neoadjuvant chemotherapy prior to nephroureterectomy for upper tract urothelial carcinoma.

Bempegaldesleukin plus nivolumab in first-line renal cell carcinoma: results from the PIVOT-02 study.

Background: Immune checkpoint inhibitor-based combinations have expanded the treatment options for patients with renal cell carcinoma (RCC); however, tolerability remains challenging. The aim of this study was to evaluate the safety and efficacy of the immunostimulatory interleukin-2 cytokine prodrug bempegaldesleukin (BEMPEG) plus nivolumab (NIVO) as first-line therapy in patients with advanced clear-cell RCC.

Methods: This was an open-label multicohort, multicenter, single-arm phase 1/2 study; here, we report results from the phase 1/2 first-line RCC cohort (N=49).

MTAP deficiency creates an exploitable target for antifolate therapy in 9p21-loss cancers.

Methylthioadenosine phosphorylase, an essential enzyme for the adenine salvage pathway, is often deficient (MTAP) in tumors with 9p21 loss and hypothetically renders tumors susceptible to synthetic lethality by antifolates targeting de novo purine synthesis. Here we report our single arm phase II trial (NCT02693717) that assesses pemetrexed in MTAP urothelial carcinoma (UC) with the primary endpoint of overall response rate (ORR). Three of 7 enrolled MTAP patients show response to pemetrexed (ORR 43%).
