The FDA has approved datopotamab deruxtecan (Datroway – Daiichi Sankyo/AstraZeneca), a trophoblast cell-surface antigen-2 (Trop-2)-directed antibody and topoisomerase inhibitor conjugate, for treatment of adults with unresectable or metastatic hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative breast cancer who received prior endocrine-based therapy and chemotherapy for unresectable or metastatic disease.

Avmapki Fakzynja Co-Pack (Verastem), a combination of the kinase inhibitors avutometinib and defactinib, has received accelerated approval from the FDA for treatment of KRAS-mutated recurrent low-grade serous ovarian cancer in women who had previously received systemic therapy.

Lefamulin (Xenleta – Nabriva), a semisynthetic pleuromutilin antibiotic, has been approved by the FDA for IV and oral treatment of community-acquired bacterial pneumonia (CABP) in adults. It is the first systemic pleuromutilin antibiotic to be approved in the US; retapamulin (Altabax), a 1% topical ointment for treatment of impetigo, was approved in 2007.

Rheumatoid arthritis (RA) is prevalent in 0.5% of adults in the US; it is about 2.5 times more common in women than in men.
