Clinical Outcomes With Immune Checkpoint Inhibitors in Patients With FGFR2/3, MTAP or ERBB2 Genomic Alterations in Advanced Urothelial Carcinoma.

Background: FGFR2/3, MTAP and ERBB2 genomic alterations have treatment targets in advanced urothelial carcinoma (aUC). These alterations may affect tumor microenvironment and outcomes with immune checkpoint inhibitors (ICIs) in aUC.

Patients And Methods: We identified patients with available genomic data in our multi-institution cohort of patients with aUC treated with ICI.

Real-world Effectiveness of Single-Agent Enfortumab Vedotin in Patients With Advanced Urothelial Carcinoma.

Background: Enfortumab vedotin (EV) is a nectin-4-directed antibody and microtubule inhibitor conjugate indicated for patients with metastatic urothelial carcinoma (mUC) who have received prior platinum-based chemotherapy and PD-1/L1 inhibitors or are ineligible for cisplatin-containing regimens and have undergone at least 1 prior line of therapy. EV is also indicated in combination with pembrolizumab in the first-line setting. However, real-world effectiveness of EV based on treatment line and impact of prior therapy remains unclear.

An Upgraded Solid-Phase Assembly of Chelators (DOTA and NOTA) Enabled Bacterial Uptake Studies of Radiolabeled Peptide.

Among popular radio metal chelators, DOTA and NOTA have been remarkably considered in radionuclide therapy and imaging studies due to several advantages in pharmacology. Here, we developed a practical and general method for assembling DOTA and NOTA in the solid phase peptide (pseudo-dilute conditions) using a wide range of solvents with easily accessible and economical feedstocks, which mitigated unprecedented challenges associated with previously reported methods. This upgraded approach enabled an efficient installation of these two chelators on various bioactive peptide sequences.

Isoprene nitrates drive new particle formation in Amazon's upper troposphere.

New particle formation (NPF) in the tropical upper troposphere is a globally important source of atmospheric aerosols. It is known to occur over the Amazon basin, but the nucleation mechanism and chemical precursors have yet to be identified. Here we present comprehensive in situ aircraft measurements showing that extremely low-volatile oxidation products of isoprene, particularly certain organonitrates, drive NPF in the Amazonian upper troposphere.
