Aducanumab-avwa (Aduhelm – Biogen/Eisai), an IV amyloid beta-directed monoclonal antibody, has received accelerated approval from the FDA for treatment of Alzheimer's disease. The approval was based on the surrogate endpoint of reduction in amyloid beta plaques in the brain. The manufacturer is required to conduct an additional randomized controlled trial to establish that reducing amyloid beta plaques with aducanumab improves clinical outcomes in patients with Alzheimer's disease.

Zanidatamab-hrii (Ziihera – Jazz), a bispecific HER2-directed antibody, has received accelerated approval from the FDA for treatment of unresectable or metastatic HER2-positive (IHC 3+) biliary tract cancer in patients who received prior therapy. Biliary tract cancer includes gallbladder cancer and intrahepatic and extrahepatic cholangiocarcinoma. Zanidatamab is the first dual HER2-targeted therapy to be approved in the US for this indication. Accelerated approval was based on the overall response rate and duration of response.

The FDA has approved tremelimumab-actl (Imjudo – AstraZeneca), a cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) blocking antibody, for use in combination with the programmed death-ligand 1 (PD-L1) blocking antibody durvalumab (Imfinzi) and platinum-based chemotherapy for treatment of metastatic non-small cell lung cancer (NSCLC) in adults with no sensitizing epidermal growth factor receptor (EGFR) mutations or anaplastic lymphoma kinase (ALK) genomic tumor aberrations.

The FDA has approved the recombinant chimeric anti-CD20 antibody ublituximab-xiiy (Briumvi – TG Therapeutics) for IV treatment of adults with relapsing forms of multiple sclerosis (MS), including clinically isolated syndrome (initial neurological episode), relapsing-remitting disease, and active secondary progressive MS (SPMS). Two other anti-CD20 antibodies, IV ocrelizumab (Ocrevus) and SC ofatumumab (Kesimpta), are also FDA-approved for these indications.

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.

The FDA has issued an Emergency Use Authorization (EUA) for Regeneron's investigational monoclonal antibodies casirivimab and imdevimab (REGEN-COV) to be administered together by IV infusion or SC injection for treatment of mild to moderate COVID-19 in adults and pediatric patients (≥12 years old and weigh ≥40 kg) who are at high risk of progressing to severe COVID-19 and/or hospitalization.

Donanemab-azbt (Kisunla – Lilly), an IV amyloid beta-directed monoclonal antibody, has been approved by the FDA for treatment of Alzheimer's disease (AD). The label states that the drug should only be started in patients with mild cognitive impairment (MCI) or mild dementia. Donanemab is the third IV amyloid beta-directed monoclonal antibody to be marketed in the US. Lecanemab (Leqembi – Biogen/Eisai) was approved by the FDA in 2023 for the same indication as donanemab. Aducanumab (Aduhelm – Lilly) was granted accelerated approval in 2021, but it was withdrawn from the market...

The FDA has approved Combogesic IV (Hikma), an IV solution containing acetaminophen and ibuprofen, to treat mild to moderate pain (alone) or moderate to severe pain (in combination with an opioid) in adults when IV analgesia is considered clinically necessary.

The FDA has approved Aurlumyn (Eicos Sciences), an IV formulation of the prostacyclin analog iloprost, to reduce the risk of digit amputation in adults with severe frostbite. Iloprost is the first drug to be approved by the FDA for treatment of severe frostbite; it has been used off-label for this indication in the EU and elsewhere for decades. In the US, iloprost is also available as an inhaled formulation (Ventavis) for treatment of pulmonary arterial hypertension.

Betibeglogene autotemcel (Zynteglo — Bluebird Bio), an autologous lentiviral vector cell-based gene therapy, has been approved by the FDA for one-time treatment of transfusion-dependent beta thalassemia in children and adults. Exagamglogene autotemcel (Casgevy), a cell-based gene therapy that uses CRISPR/Cas9 gene-editing technology, was approved earlier this year for the same indication in patients ≥12 years old.
