Amivantamab in EGFR Exon 20 Insertion-Mutated Non-Small-Cell Lung Cancer Progressing on Platinum Chemotherapy: Initial Results From the CHRYSALIS Phase I Study.

J Clin Oncol 2021 Aug 2:JCO2100662. Epub 2021 Aug 2.

Janssen R&D, Spring House, PA.

Purpose: Non-small-cell lung cancer (NSCLC) with epidermal growth factor receptor () exon 20 insertion (Exon20ins) mutations exhibits inherent resistance to approved tyrosine kinase inhibitors. Amivantamab, an EGFR-MET bispecific antibody with immune cell-directing activity, binds to each receptor's extracellular domain, bypassing resistance at the tyrosine kinase inhibitor binding site.

Methods: CHRYSALIS is a phase I, open-label, dose-escalation, and dose-expansion study, which included a population with Exon20ins NSCLC. Read More

Review of chemotherapy-associated paronychia.

Int J Dermatol 2021 Jul 9. Epub 2021 Jul 9.

Department of Dermatology, Weill Cornell Medicine, New York City, New York, USA.

Chemotherapy-associated paronychia (CAP) is an inflammation of the nail folds in response to various chemotherapeutic medications. Altered proliferation of keratinocytes or nail matrix stem cells is thought to be a major causative factor. Prophylactic tetracyclines, topical povidone-iodine, and general irritation avoidance measures are among some of the recommended interventions for CAP. Read More

In many nail unit infections, the clinical presentation is nonspecific: in these cases, diagnostic tests are mandatory before treatment, to avoid spread of the infection and drug resistance. The most common forms of bacterial and viral infections that may affect the nail unit are herein described in detail, with diagnostic and treatment options provided. Read More
