Adjuvant Nivolumab versus Placebo in Muscle-Invasive Urothelial Carcinoma.

Background: The role of adjuvant treatment in high-risk muscle-invasive urothelial carcinoma after radical surgery is not clear.

Methods: In a phase 3, multicenter, double-blind, randomized, controlled trial, we assigned patients with muscle-invasive urothelial carcinoma who had undergone radical surgery to receive, in a 1:1 ratio, either nivolumab (240 mg intravenously) or placebo every 2 weeks for up to 1 year. Neoadjuvant cisplatin-based chemotherapy before trial entry was allowed.

Fibroblast Growth Factor Receptor 3 Alterations and Response to PD-1/PD-L1 Blockade in Patients with Metastatic Urothelial Cancer.

Prior studies have demonstrated that fibroblast receptor 3 (FGFR3)-mutant urothelial cancers (UCs) are associated with decreased T-cell infiltration. As FGFR3 mutations are enriched in luminal-like UC and luminal-like UC has been shown to be relatively less responsive to PD-1/PD-L1 inhibition (checkpoint inhibition [CPI]), these data have led to the speculation that FGFR3 mutations may be causally related to poor T-cell infiltration and that UC patients harboring FGFR3 mutations may be suboptimal candidates for CPI. Using data derived from two clinical trials exploring CPI in metastatic UC, we demonstrate no statistically significant difference in response rates in patients with FGFR3-mutant versus wild-type UC.

Nivolumab Alone and With Ipilimumab in Previously Treated Metastatic Urothelial Carcinoma: CheckMate 032 Nivolumab 1 mg/kg Plus Ipilimumab 3 mg/kg Expansion Cohort Results.

Purpose: CheckMate 032 is an open-label, multicohort study that includes patients with unresectable locally advanced or metastatic urothelial carcinoma (mUC) treated with nivolumab 3 mg/kg monotherapy every 2 weeks (NIVO3), nivolumab 3 mg/kg plus ipilimumab 1 mg/kg every 3 weeks for four doses followed by nivolumab monotherapy 3 mg/kg every 2 weeks (NIVO3+IPI1), or nivolumab 1 mg/kg plus ipilimumab 3 mg/kg every 3 weeks for four doses followed by nivolumab monotherapy 3 mg/kg every 2 weeks (NIVO1+IPI3). We report on the expanded NIVO1+IPI3 cohort and extended follow-up for the NIVO3 and NIVO3+IPI1 cohorts.

Methods: Patients with platinum-pretreated mUC were enrolled in this phase I/II multicenter study to receive NIVO3, NIVO3+IPI1, or NIVO1+IPI3 until disease progression or unacceptable toxicity.

A multi-arm phase I dose escalating study of an oral NOTCH inhibitor BMS-986115 in patients with advanced solid tumours.

Background Inhibiting Notch is a promising anti-cancer strategy as it plays a critical role in cancer stem cells maintenance and tumour angiogenesis. BMS-986115 is an orally active, selective inhibitor of gamma-secretase mediated Notch signalling. Method Two dose escalation schedules (Arm-A continuous daily schedule and Arm-B intermittent 2 times weekly schedule) of BMS-986115 were evaluated in advanced solid tumour patients.

Gamma Secretase Inhibition by BMS-906024 Enhances Efficacy of Paclitaxel in Lung Adenocarcinoma.

Notch signaling is aberrantly activated in approximately one third of non-small cell lung cancers (NSCLC). We characterized the interaction between BMS-906024, a clinically relevant Notch gamma secretase inhibitor, and front-line chemotherapy in preclinical models of NSCLC. Chemosensitivity assays were performed on 14 human NSCLC cell lines.

Discovery of Clinical Candidate BMS-906024: A Potent Pan-Notch Inhibitor for the Treatment of Leukemia and Solid Tumors.

Structure-activity relationships in a series of (2-oxo-1,4-benzodiazepin-3-yl)-succinamides identified highly potent inhibitors of γ-secretase mediated signaling of Notch1/2/3/4 receptors. On the basis of its robust in vivo efficacy at tolerated doses in Notch driven leukemia and solid tumor xenograft models, 12 (BMS-906024) was selected as a candidate for clinical evaluation.

The effects of liver impairment on the pharmacokinetics of brivanib, a dual inhibitor of fibroblast growth factor receptor and vascular endothelial growth factor receptor tyrosine kinases.

Purpose: Hepatic impairment may impede tyrosine kinase inhibitor metabolism. This phase I study compared the pharmacokinetics of brivanib in patients with hepatocellular carcinoma (HCC) and varying levels of hepatic impairment with those with non-HCC malignancies and normal liver function.

Methods: Patients were assigned to the following groups: Groups A, B, and C (HCC plus mild, moderate, or severe hepatic impairment, respectively) and Group D (non-HCC malignancy and normal hepatic function).

Metabolism, excretion, and pharmacokinetics of oral brivanib in patients with advanced or metastatic solid tumors.

The goal of this study was to evaluate the pharmacokinetics, mass balance, metabolism, routes and extent of elimination, and safety of a single oral dose of (14)C-labeled brivanib alaninate and the safety and tolerability of brivanib after multiple doses in patients with advanced or metastatic solid tumors. This was a two-part, single-center, open-label, single oral-dose (part A) followed by multiple-dose (part B) study in patients with advanced or metastatic solid tumors. In part A, patients received a single dose of [(14)C]brivanib alaninate and in part B patients received 800 mg of nonradiolabeled brivanib alaninate every day.

JAK2 V617F patients with essential thrombocythemia present with clinical features of polycythemia vera.

Recent studies have shown that Janus tyrosine kinase 2 (JAK2) V617F mutation is found in nearly all patients with polycythemia vera (PV) and underlie the basis of PV molecular pathogenesis. Moreover, JAK2 V617F patients with essential thrombocythemia (ET) have been found to have some clinical features similar to PV. To determine whether the same is true in a different Chinese patient population, we employed Allele-specific polymerase chain reaction in combination with sequence analysis to investigate the point mutation in a series of Chinese patients with hematological malignancies.
