The FDA has warned that the investigational long-acting monoclonal antibodies tixagevimab and cilgavimab (Evusheld – AstraZeneca) are unlikely to neutralize the XBB.1.5 Omicron variant of SARS-CoV-2. Evusheld is available under an Emergency Use Authorization (EUA) for IM pre-exposure prophylaxis of COVID-19 in persons ≥12 years old who weigh ≥40 kg and have either a history of a severe adverse reaction that prevents their vaccination against COVID-19 or moderate or severe immune compromise.
Recently published guidelines from the American Diabetes Association (ADA) and the Kidney Disease: Improving Global Outcomes (KDIGO) Diabetes Work Group recommend addition of the oral nonsteroidal mineralocorticoid receptor antagonist (MRA) finerenone (Kerendia) to standard treatment in patients with type 2 diabetes and chronic kidney disease (CKD).

The short-acting formulation of mixed amphetamine salts (Adderall, and generics) FDA-approved for treatment of attention-deficit hyperactivity disorder (ADHD) and narcolepsy, is currently in short supply in the US. Until an adequate supply is restored, patients may be looking for alternatives.
The FDA has approved Furoscix (scPharmaceuticals), a subcutaneous formulation of the loop diuretic furosemide administered via a single-use, on-body infusor, for treatment of congestion due to fluid overload in adults with New York Heart Association (NYHA) Class II-III chronic heart failure (HF). Furosemide (Lasix, and generics) has been available for years in oral and IV formulations.
In Brief: A New Indication for Dabrafenib (Tafinlar) and Trametinib (Mekinist) Combination Therapy (online only)
The oral kinase inhibitors dabrafenib (Tafinlar – GSK) and trametinib (Mekinist – Novartis) have received accelerated approval by the FDA for use together for a fifth indication: treatment of unresectable or metastatic solid tumors with a BRAF V600E mutation in patients ≥6 years old who have progressed following prior treatment and have no satisfactory alternative treatment options. The combination is not approved for treatment of colorectal cancer because of known intrinsic resistance to BRAF inhibition and dabrafenib is not approved for use in patients with wild-type BRAF melanoma, anaplastic thyroid cancer (ATC), or solid tumors.
Lecanemab-irmb (Leqembi – Biogen/Eisai), an IV amyloid beta-directed monoclonal antibody, has received accelerated approval from the FDA for treatment of Alzheimer's disease. The label states that treatment with Leqembi should be initiated in patients with mild cognitive impairment (MCI) or mild dementia, the population in which the drug was initiated in clinical trials. Lecanemab is the second IV amyloid-beta directed monoclonal antibody to be approved for this indication; aducanumab (Aduhelm) was approved in 2021 and has the same restrictions on treatment initiation.
Etranacogene dezaparvovec-drlb (Hemgenix – CSL Behring), an adeno-associated virus vector-based gene therapy, has been approved by the FDA for treatment of hemophilia B in adults who currently receive factor IX prophylaxis therapy or have had life-threatening or repeated, serious, spontaneous bleeding episodes. It is the first gene therapy to be approved in the US for this indication.
The FDA has approved the subcutaneously injected interleukin (IL)-4 receptor alpha antagonist dupilumab (Dupixent – Sanofi/Regeneron) for treatment of eosinophilic esophagitis (EoE) in patients ≥12 years old who weigh ≥40 kg and treatment of prurigo nodularis in adults. Dupilumab is the first drug to be approved in the US for each of these indications. It is also FDA-approved for treatment of atopic dermatitis, asthma, and chronic rhinosinusitis with nasal polyposis.
Epsolay (Galderma), a 5% benzoyl peroxide cream, has been approved by the FDA for treatment of inflammatory lesions of rosacea in adults. It is the first product containing benzoyl peroxide to be approved in the US for treatment of rosacea. Benzoyl peroxide formulations approved for acne have been used off-label to treat rosacea for years, but itching and burning have limited their use.
The FDA has approved a dextroamphetamine transdermal patch (Xelstrym – Noven) for once-daily treatment of attention-deficit/hyperactivity disorder (ADHD) in patients ≥6 years old. Xelstrym is the first transdermal amphetamine product to be approved in the US. A methylphenidate transdermal patch (Daytrana, and generics) has been available for years for treatment of ADHD.
