Elranatamab-bcmm (Elrexfio – Pfizer), a bispecific B-cell maturation antigen (BCMA)-directed CD3 T-cell engager, has been granted accelerated approval by the FDA for treatment of relapsed or refractory multiple myeloma in adults who received ≥4 prior lines of therapy, including a proteasome inhibitor, an immunomodulatory drug, and an anti-CD38 monoclonal antibody. Accelerated approval was based on the response rate and durability of response. Elranatamab is the second bispecific BCMA-directed CD3 T-cell engager to be approved for this indication; teclistamab (Tecvayli) was the...

The FDA has granted regular approval to the oral kinase inhibitor tepotinib (Tepmetko – EMD Serono) for treatment of adults with metastatic non-small cell lung cancer (NSCLC) harboring mesenchymal-epithelial transition (MET) exon 14 skipping alterations. MET exon 14 skipping mutations occur in 3-4% of NSCLC cases and are associated with advanced disease and a poor prognosis. Tepotinib received accelerated approval for the same indication in 2021 based on initial overall response rates and duration of response.

Lyme disease in the US is caused by the spirochete Borrelia burgdorferi, which is transmitted to humans by Ixodes scapularis (blacklegged [deer] tick) and I. pacificus (western blacklegged tick). Most cases of Lyme disease occur in late spring and early summer in northeastern and mid-Atlantic states, the upper Midwest, and in northern California. B. mayonii, which is also transmitted by I. scapularis, has been shown to cause a similar illness in the upper Midwest.

The FDA has licensed two new pneumococcal conjugate vaccines (PCVs) for prevention of invasive pneumococcal disease in adults: Prevnar 20 (PCV20; Pfizer), which contains antigens from 20 serotypes of pneumococcus, and Vaxneuvance (PCV15; Merck), which contains antigens from 15 serotypes. Two other pneumococcal vaccines are available in the US: Prevnar 13 (PCV13; Pfizer), a 13-valent conjugate vaccine licensed for use in persons ≥6 weeks old, and Pneumovax 23 (PPSV23; Merck), a 23-valent pneumococcal polysaccharide vaccine licensed for use in persons ≥2 years...

Most patients with multiple sclerosis (MS) present with the relapsing-remitting form of the disease. Pharmacologic treatment usually includes a disease-modifying drug, corticosteroids for acute exacerbations, and other drugs for managing symptoms such as fatigue, depression, and pain. Early use of disease-modifying therapy has improved clinical outcomes.

An intrathecal formulation of the muscle relaxant baclofen (Lioresal Intrathecal - Medtronic) has been approved by the US Food and Drug Administration for treatment of spasticity due to multiple sclerosis (MS) or spinal cord injury. Its use requires subcutaneous implantation of a drug pump, which infuses the drug into the subarachnoid space. Baclofen (Lioresal [Ciba-Geigy], and others) has been available as an oral formulation for many years (Medical Letter 20:43, 1978), but its use has been limited by central-nervous-system effects such as drowsiness and confusion.

Lansoprazole (Prevacid -TAP), a proton pump inhibitor similar to omeprazole (Prilosec - Medical Letter, 32:19, 1990), has been approved by the US Food and Drug Administration for short-term treatment of active duodenal ulcer and erosive reflux esophagitis and for long-term treatment of chronic hypersecretory conditions, including the Zollinger-Ellison syndrome.

Risedronate (Actonel - Procter & Gamble), a pyridinyl bisphosphonate, has been approved by the FDA for oral treatment of Paget's disease of bone. Characterized by excessive bone resorption, bony deformity, disorganized bone remodeling and structural weakness, Paget's disease occurs in up to 3% of people older than 55 in Europe and North America (PD Delmas and PJ Meunier, N Engl J Med, 336:558, 1997).

Infliximab, a monoclonal antibody that inhibits tumor necrosis factor, has received an accelerated approval from the FDA for intravenous treatment of moderate to severe Crohn's disease refractory to other medical treatment.
