Valoctocogene roxaparvovec-rvox (Roctavian – Biomarin), an adeno-associated virus (AAV) vector-based gene therapy, has been approved by the FDA for one-time treatment of severe hemophilia A in adults without pre-existing antibodies to AAV serotype 5. It is the first gene therapy to be approved in the US for treatment of hemophilia A.

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.

Vimseltinib (Romvimza – Deciphera), an oral kinase inhibitor, has been approved by the FDA for treatment of symptomatic tenosynovial giant cell tumor in adults for whom surgical resection would cause worsening functional limitation or severe morbidity. The kinase inhibitor pexidartinib (Turalio) was approved for a similar indication in 2019.

Dordaviprone (Modeyso – Jazz), an oral protease activator, has received accelerated approval from the FDA for treatment of diffuse midline gliomas harboring a H3 K27M mutation in patients ≥ year old who had disease progression following prior treatment. It is the first drug to be approved in the US for this indication.

The FDA has approved the interleukin-2 (IL-2) receptor-directed fusion protein denileukin diftitox (Lymphir – Citius) for treatment of relapsed or refractory stage I-III cutaneous T-cell lymphoma in adults who received at least one prior systemic therapy. Lymphir is a reformulated, purified version of Ontak, which was voluntarily withdrawn from the market in 2014 because of manufacturing issues.

The FDA has approved Viekira Pak (Abbvie), a fixed-dose combination of two new direct-acting antiviral agents (ombitasvir, paritaprevir) with the pharmacologic enhancer ritonavir in one tablet, co-packaged with a third new direct-acting antiviral agent (dasabuvir) in a second tablet, for oral treatment of chronic hepatitis C virus (HCV) genotype 1 infection. Genotype 1 is responsible for 70-80% of HCV infections in the US.

The FDA has approved pitolisant (Wakix – Harmony), a histamine-3 (H₃)-receptor antagonist/inverse agonist, for treatment of excessive daytime sleepiness (EDS) or cataplexy in adults with narcolepsy. It is the first H₃-receptor antagonist/inverse agonist to become available in the US and the first non-controlled substance to receive FDA approval for these indications. Pitolisant has been available in Europe since 2016.

The FDA has approved Winlevi (Sun), a 1% cream formulation of the androgen receptor inhibitor clascoterone, for treatment of acne vulgaris in patients ≥12 years old. It is the first topical androgen receptor inhibitor to be approved by the FDA.

Alosetron hydrochloride (Lotronex - Glaxo Welcome), a selective serotonin receptor antagonist, has received FDA approval for treatment of irritable bowel syndrome (IBS) in women whose primary bowel symptom is diarrhea.
