Three extended-release injectable formulations of second-generation antipsychotic drugs — two of risperidone (Rykindo, Uzedy) and one of aripiprazole (Abilify Asimtufii) — have been approved by the FDA for treatment of schizophrenia in adults. Rykindo and Abilify Asimtufii are also approved for maintenance treatment of bipolar I disorder in adults. Other extended-release injectable formulations of risperidone and aripiprazole have been available in the US for years (see Table 1).

The antisense oligonucleotide viltolarsen (Viltepso – NS Pharma) has received accelerated approval from the FDA for treatment of Duchenne muscular dystrophy (DMD) in patients who have mutations of the dystrophin gene that are amenable to exon 53 skipping (DMD-53). It is the second drug to be approved for this indication; the antisense oligonucleotide golodirsen (Vyondys 53) was approved in 2019.

Lecanemab-irmb (Leqembi – Eisai/Biogen), the IV amyloid-directed monoclonal antibody that received accelerated approval from the FDA in January 2023 for treatment of early Alzheimer's disease, has now received full approval from the FDA based on a trial showing that it slowed cognitive and functional decline in patients with mild cognitive impairment (MCI) or mild Alzheimer's disease dementia and confirmed presence of brain amyloid. The IV amyloid-directed monoclonal antibody aducanumab (Aduhelm) has received only an accelerated FDA-approval for the same indication.

Concizumab (Alhemo – Novo Nordisk), a subcutaneously injected tissue factor pathway inhibitor (TFPI) antagonist, has been approved by the FDA for routine prophylaxis to prevent or reduce the frequency of bleeding episodes in patients ≥12 years old who have hemophilia A with factor VIII inhibitors or hemophilia B with factor IX inhibitors. It is the second TFPI antagonist to be approved in the US for treatment of hemophilia A or B; the TFPI antagonist marstacimab (Hympavzi) is approved for use in patients without inhibitors.

Penpulimab-kcqx (Anniko – Akeso Biopharma), a programmed death receptor-1 (PD-1)-blocking antibody, has been approved by the FDA for use in combination with cisplatin or carboplatin plus gemcitabine for first-line treatment of recurrent or metastatic nonkeratinizing nasopharyngeal carcinoma and for use as monotherapy for metastatic disease in adults with disease progression on or after platinum-based chemotherapy and at least one other prior line of therapy. Penpulimab is the second immune checkpoint inhibitor to be approved in the US for treatment of nasopharyngeal carcinoma;...

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...

The sodium-glucose cotransporter 2 (SGLT2) inhibitor dapagliflozin (Farxiga – AstraZeneca) was approved by the FDA in 2020 to reduce the risk of cardiovascular death and hospitalization for heart failure (HF) in adults with heart failure with reduced ejection fraction (HFrEF). The indication has now been expanded to include a reduction in the risk of urgent HF visits and use in adults with any left ventricular ejection fraction (LVEF).

A new 2023-2024 formulation of the adjuvanted protein subunit COVID-19 vaccine manufactured by Novavax that was developed to more closely target currently circulating SARS-CoV-2 variants has been made available in the US under an FDA Emergency Use Authorization (EUA) for use in persons ≥12 years old. The original formulation of the Novavax vaccine is no longer authorized for use in the US. In September, updated formulations of the mRNA COVID-19 vaccines manufactured by Pfizer/BioNTech (Comirnaty) and Moderna (Spikevax) were licensed by the FDA for use in persons ≥12 years old and...
