Safety and efficacy of letetresgene autoleucel alone or with pembrolizumab for relapsed/refractory multiple myeloma.

This pilot study assessed the safety and efficacy of letetresgene autoleucel (lete-cel; GSK3377794), a genetically modified autologous T-cell therapy targeting New York esophageal squamous cell carcinoma-1 (NY-ESO-1)/L antigen family member 1 isoform A (LAGE-1a)-positive myeloma cells, alone or in combination with pembrolizumab in patients with relapsed/refractory multiple myeloma. Eligible patients expressed NY-ESO-1 and/or LAGE-1a and either HLA-A∗02:01, ∗02:05, or ∗02:06. Patients received lete-cel single infusion alone (arm 1) or with pembrolizumab (arm 2).

The Utility of Preoperative Vascular Grading in Patients Undergoing Surgery First for Pancreatic Cancer: Does Radiologic Arterial or Venous Involvement Predict Pathologic Margin Status?

Controversy exists on accurately grading vascular involvement on preoperative imaging for pancreatic ductal adenocarcinoma. We reviewed the association between preoperative imaging and margin status in 137 patients. Radiologists graded venous involvement based on the Ishikawa classification system and arterial involvement based on preoperative imaging.

Cerenkov Luminescence Imaging as a Modality to Evaluate Antibody-Based PET Radiotracers.

Unlabelled: Antibodies, and engineered antibody fragments, labeled with radioisotopes are being developed as radiotracers for the detection and phenotyping of diseases such as cancer. The development of antibody-based radiotracers requires extensive characterization of their in vitro and in vivo properties, including their ability to target tumors in an antigen-selective manner. In this study, we investigated the use of Cerenkov luminescence imaging (CLI) as compared with PET as a modality for evaluating the in vivo behavior of antibody-based radiotracers.

Oligoclonal antibodies to target the ErbB family.

Introduction: Use of mAbs to inhibit signaling through the ErbB receptor tyrosine kinase family has proven to be an effective strategy for treating ErbB-driven cancers. Advances in the field of antibody engineering and manufacturing now allow us to more effectively mimic the natural immune response by generating oligoclonal mixtures of antibodies against desired targets of interest.

Areas Covered: In this review, we examine the literature describing the development of oligoclonal mixtures of antibodies against ErbB family members and the impact of those mixtures on preclinical and clinical efficacy.

Combining anti-ERBB3 antibodies specific for domain I and domain III enhances the anti-tumor activity over the individual monoclonal antibodies.

Background: Inappropriate signaling through the epidermal growth factor receptor family (EGFR1/ERBB1, ERBB2/HER2, ERBB3/HER3, and ERBB4/HER4) of receptor tyrosine kinases leads to unregulated activation of multiple downstream signaling pathways that are linked to cancer formation and progression. In particular, ERBB3 plays a critical role in linking ERBB signaling to the phosphoinositide 3-kinase and Akt signaling pathway and increased levels of ERBB3-dependent signaling is also increasingly recognized as a mechanism for acquired resistance to ERBB-targeted therapies.

Methods: We had previously reported the isolation of a panel of anti-ERBB3 single-chain Fv antibodies through use of phage-display technology.

Spread of extensively resistant VIM-2-positive ST235 Pseudomonas aeruginosa in Belarus, Kazakhstan, and Russia: a longitudinal epidemiological and clinical study.

Background: Multidrug-resistant and extensively-drug-resistant Pseudomonas aeruginosa are increasing therapeutic challenges worldwide. We did a longitudinal epidemiological and clinical study of extensively-drug-resistant P aeruginosa in Belarus, Kazakhstan, and Russia.

Methods: The study was done in three prospectively defined phases: Jan 1, 2002-Dec 31, 2004; Jan 1, 2006-Dec 31, 2007; and Jan 1, 2008-Dec 31, 2010.
