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.

Drugs for gout are used to reduce the pain and inflammation of acute flares, decrease the frequency of exacerbations, and lower serum urate levels to prevent recurrent flares, development of tophi, and joint damage.

The investigational monoclonal antibodies casirivimab and imdevimab (REGEN-COV – Regeneron) have been available in the US under an Emergency Use Authorization (EUA) since late 2020 for use together to treat mild to moderate COVID-19 in persons ≥12 years old who weigh ≥40 kg and are at high risk of progression to severe disease or hospitalization. The FDA has now expanded this EUA to allow use of the antibodies together for post-exposure prophylaxis of COVID-19 in such persons, if they are not fully vaccinated against COVID-19 or are unlikely to have an adequate immune response...

Tarlatamab-dlle (Imdelltra – Amgen), a first-in-class bispecific delta-like ligand 3 (DLL3)-directed CD3 T-cell engager, has received accelerated approval from the FDA for treatment of extensive-stage small cell lung cancer (SCLC) in adults who had disease progression on or after platinum-based chemotherapy. It is the first bispecific DLL3-directed CD3 T-cell engager to be approved in the US for this indication. Most patients with SCLC have a response to initial treatment, but progression generally occurs within a few months and overall survival is usually less than 8 months....

Marstacimab-hncq (Hympavzi – Pfizer), a 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 without factor VIII inhibitors or hemophilia B without factor IX inhibitors. It is the first hemophilia treatment to be approved in the US that targets an inhibitor of coagulation and the first to become available in prefilled pens and syringes for subcutaneous administration.

IV antiviral drug remdesivir (Veklury) has now been FDA-approved for treatment of COVID-19 in patients ≥28 days old who weigh ≥3 kg and are either hospitalized or at high risk for progression to severe disease. Remdesivir was already FDA-approved for these indications in patients ≥12 years old who weigh ≥40 kg; it was available under an Emergency Use Authorization (EUA) for younger or lighter patients. Remdesivir is the first drug to be FDA-approved for treatment of COVID-19 in children <12 years old.

Rozanolixizumab-noli (Rystiggo – UCB), a neonatal Fc receptor (FcRn) blocker, has been approved by the FDA for treatment of generalized myasthenia gravis in adults with anti-acetylcholine receptor (AChR) or anti-muscle-specific tyrosine kinase (MuSK) antibodies. It is the first drug to be approved for treatment of generalized myasthenia gravis in patients with anti-MuSK antibodies. Four other biologic drugs – the FcRn blocker efgartigimod alfa (Vyvgart; Vyvgart Hytrulo) and the complement inhibitors eculizumab (Soliris), ravulizumab (Ultomiris), and zilucoplan (Zilbrysq) – are...

The motor symptoms of Parkinson's disease (PD) are caused primarily by degeneration of dopaminergic neurons in the substantia nigra. The nonmotor symptoms of the disease are thought to be caused by degeneration of other neurotransmitter systems. No disease-modifying drugs are available for treatment of PD.

Ocrevus Zunovo (Genentech), a subcutaneous (SC) formulation of the anti-CD20 monoclonal antibody ocrelizumab plus human recombinant hyaluronidase-ocsq has been approved by the FDA for treatment of primary progressive and relapsing forms of multiple sclerosis (MS). Intravenous ocrelizumab (Ocrevus), which was approved for the same indications in 2017, is one of the most commonly prescribed drugs for treatment of MS. Ocrelizumab remains the only drug approved for treatment of primary progressive MS.

The investigational monoclonal antibody bebtelovimab (LY-CoV1404 – Lilly) has been granted an FDA Emergency Use Authorization (EUA) for IV treatment of mild to moderate COVID-19 in patients ≥12 years old who weigh ≥40 kg and are at high risk of progressing to severe disease, including hospitalization and death, and for whom alternative treatment options are unavailable or inappropriate. Bebtelovimab is active against the Omicron variant of SARS-CoV-2; sotrovimab (VIR-7831) is the only other monoclonal antibody currently available for treatment of COVID-19 that is active...
