The FDA has issued an Emergency Use Authorization (EUA) for Lilly's investigational monoclonal antibodies bamlanivimab (LY-CoV555) and etesevimab (LY-CoV016) to be administered together for 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 and/or hospitalization (see Table 1). Bamlanivimab received an EUA for use as monotherapy in such patients in November 2020. Regeneron's investigational monoclonal antibodies casirivimab (REGN10933) and imdevimab (REGN10987) are also authorized for use...

Panitumumab (Vectibix - Amgen), a fully human IgG₂ monoclonal antibody that inhibits the epidermal growth factor receptor (EGFR), has been approved by the FDA for treatment of patients with EGFR-expressing metastatic colorectal cancer that has progressed despite standard chemotherapy. It is the second monoclonal antibody EGFR inhibitor to be approved for metastatic colorectal cancer; cetuximab (Erbitux), a human-murine chimeric IgG₁ monoclonal antibody, was approved in 2004.

Reteplase (Retavase - Boehringer Mannheim), a recombinant protein derivative of human tissue plasminogen activator (t-PA), has been marketed in the USA for thrombolysis in patients with acute myocardial infarction.

Axatilimab-csfr (Niktimvo – Incyte), a colony stimulating factor-1 receptor-blocking antibody, has been approved by the FDA for intravenous treatment of chronic graft-versus-host disease (cGVHD) after failure of at least 2 lines of systemic therapy in patients weighing ≥40 kg. Corticosteroids are generally the first-line treatment for cGVHD. The oral kinase inhibitors ibrutinib (Imbruvica), ruxolitinib (Jakafi), and belumosudil (Rezurock) are also approved for treatment of cGVHD. Extracorporeal photopheresis has been used off-label.

Isatuximab-irfc (Sarclisa – Sanofi), a CD38-directed cytolytic antibody, has been approved by the FDA for treatment of newly diagnosed multiple myeloma in adults who are not eligible for autologous stem cell transplantation (ASCT). The drug was approved earlier for treatment of relapsed or treatment-refractory multiple myeloma.

Disodium pamidronate (Aredia - Ciba-Geigy), an aminohydroxypropilidene bisphosphonate, has been approved by the US Food and Drug Administration for intravenous (IV) treatment of hypercalcemia associated with malignancy, with or without bone metastases. The drug is also being investigated for use in Paget's disease of bone, hyperparathyroidism, and postmenopausal osteoporosis. An oral formulation of pamidronate has been used in Europe, but is not available in the USA.

The FDA has approved ibalizumab-uiyk (Trogarzo – Theratechnologies/TaiMed), a CD4-directed monoclonal antibody, for IV treatment of multidrug-resistant HIV-1 (MDR-HIV) infection in heavily antiretroviral-experienced adults with treatment failure on their current regimen.
