Nectin-4 Expression in Prostatic Adenocarcinoma: An Immunohistochemical Study.

Background: The Nectin-4 directed antibody drug conjugate enfortumab vedotin (EV) has emerged as frontline systemic therapy in combination with immune checkpoint blockade for urothelial carcinoma (UC), capitalizing on the ubiquitous expression of this protein in UC. There is limited data available regarding expression of Nectin-4 by immunohistochemistry in prostate cancer, but this is of interest as a substantial number of UC patients likely to receive EV have concomitant prostate cancer.

Methods: Nectin-4 protein expression was evaluated by immunohistochemistry in tissue microarrays encompassing a cohort of 302 prostatic adenocarcinomas spanning Grade Groups 1-5.

Discovery of VU0467319: an M Positive Allosteric Modulator Candidate That Advanced into Clinical Trials.

Herein we detail the of VU0467319 (VU319), an M Positive Allosteric Modulator (PAM) clinical candidate that successfully completed a Phase I Single Ascending Dose (SAD) clinical trial. VU319 () is a moderately potent M PAM (M PAM EC = 492 nM ± 2.9 nM, 71.

Traumatic Unilateral Internuclear Ophthalmoplegia in a 5-Year-Old Child.

The authors present the case of a 5-year-old boy who developed a unilateral internuclear ophthalmoplegia (INO) following mild head trauma with supporting magnetic resonance imaging (MRI) findings of damage to the medial longitudinal fasciculus. At 2 months of follow-up, the patient had resolution of diplopia and only minimal residual nystagmus. Although rare in the children, INO can develop following head trauma.

Primary Chemoablation of Recurrent Low-Grade Intermediate-Risk Nonmuscle-Invasive Bladder Cancer With UGN-102: A Single-Arm, Open-Label, Phase 3 Trial (ENVISION).

Purpose: We evaluate the efficacy and safety of UGN-102 chemoablation for the primary treatment of patients with recurrent low-grade intermediate-risk nonmuscle-invasive bladder cancer.

Materials And Methods: ENVISION is an ongoing, multinational, single-arm, phase 3 study in patients with a biopsy-proven recurrence of untreated low-grade intermediate-risk nonmuscle-invasive bladder cancer. Patients received 6 weekly intravesical instillations of UGN-102 (mitomycin; outpatient setting) and were evaluated at 3 months.
