Mepolizumab is a humanized monoclonal antibody that targets interleukin-5, a cytokine that plays a central role in eosinophilic inflammation, which is present in 20 to 40% of patients with chronic obstructive pulmonary disease (COPD).

The β2 common integrin subunit CD18 is essential for leukocyte-endothelial adhesion and extravasation to inflamed or infected tissue. Damaging variants in ITGB2, which encodes CD18, cause leukocyte adhesion deficiency type I (LAD-I), an inborn error of immunity that leads to frequent life-threatening infections and a high risk of death among affected children. Allogeneic hematopoietic stem-cell transplantation (HSCT) represents a curative treatment but is limited by donor availability, a high incidence of graft-versus-host disease, and graft failure.

Secondary erythrocytosis often results from conditions that cause tissue hypoxia or an improper increase in erythropoietin (EPO) production. EPO, the major regulator of erythropoiesis, has a complex and tightly regulated expression during development, with a liver-to-kidney switch shortly after birth.

Innovative oral targeted therapies are warranted for patients with human epidermal growth factor receptor 2 (HER2)-mutant non-small-cell lung cancer (NSCLC). Zongertinib is an oral, irreversible, HER2-selective tyrosine kinase inhibitor that has been shown to have efficacy in persons with advanced or metastatic solid tumors with HER2 alterations in a phase 1 study.

Among patients with mismatch repair-deficient (dMMR), locally advanced rectal cancer, neoadjuvant checkpoint blockade eliminated the need for surgery in a high proportion of patients. Whether this approach can be extended to all early-stage dMMR solid tumors, regardless of tumor site, is unknown.
