The FDA has approved Phexxi (Evofem), a nonhormonal prescription-only vaginal gel containing lactic acid, citric acid, and potassium bitartrate, for prevention of pregnancy. The gel is intended for on-demand contraception; it is not effective when used after intercourse. It was previously approved for use as a vaginal lubricant (Amphora), but was never marketed.

The FDA has approved ozanimod (Zeposia – Celgene), a sphingosine 1-phosphate (S1P) receptor modulator, for 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). It is the third oral S1P receptor modulator to be approved in the US for treatment of relapsing forms of MS; siponimod (Mayzent) is also indicated for use in adults, and fingolimod (Gilenya) is approved for use in patients ≥10 years old.

A new CDC guideline for prescribing opioids for pain recently became available. Nonopioid drugs for pain were reviewed in a previous issue.

The FDA has approved the oral tyrosine kinase inhibitor avapritinib (Ayvakit – Blueprint Medicines) for treatment of unresectable or metastatic gastrointestinal stromal tumors (GISTs) harboring a platelet-derived growth factor receptor alpha (PDGFRA) D842V or other PDGFRA exon 18 mutation. Avapritinib is the first drug to be approved for this indication in the US.

The Bruton's tyrosine kinase (BTK) inhibitor pirtobrutinib (Jaypirca – Lilly) has received accelerated approval from the FDA for treatment of relapsed or refractory mantle cell lymphoma (MCL) in adults who received ≥2 prior lines of systemic therapy, including a BTK inhibitor. Accelerated approval was based on the response rate. The BTK inhibitors ibrutinib (Imbruvica), acalabrutinib (Calquence), and zanubrutinib (Brukinsa) are also approved for treatment of MCL.

Belzutifan (Welireg – Merck), a first-in-class hypoxia-inducible factor inhibitor, has been approved by the FDA for treatment of advanced renal cell carcinoma (RCC) in adults who received prior treatment with a programmed death receptor-1 (PD-1) or programmed death-ligand 1 (PD-L1) inhibitor and a vascular endothelial growth factor tyrosine kinase inhibitor (VEGF-TKI). Belzutifan was previously approved for use in patients with von Hippel-Lindau disease.

Fensolvi (Tolmar), a long-acting subcutaneous formulation of the gonadotropin-releasing hormone (GnRH) agonist leuprolide acetate, has been approved by the FDA for treatment of central precocious puberty (CPP) in children ≥2 years old. It is the first formulation of the drug to be approved for SC administration once every 6 months. IM formulations of leuprolide acetate, which are given once monthly or every 3 months, and the GnRH agonists histrelin acetate (Supprelin LA) and triptorelin (Triptodur) have been available for years for treatment of CPP.

The FDA recently approved axicabtagene ciloleucel (Yescarta – Kite), a CD19-directed genetically modified cellular product, for treatment of large B-cell lymphoma that is refractory to first-line chemoimmunotherapy or that relapses within 12 months of first-line treatment. It was previously approved for treatment of relapsed or refractory B-cell lymphoma after ≥2 lines of systemic therapy and for treatment of relapsed or refractory follicular lymphoma after ≥2 lines of systemic therapy. Yescarta is an individualized cellular product prepared from the patient's own T cells,...

The FDA has approved lisocabtagene maraleucel (Breyanzi – BMS) for treatment of adults with large B-cell lymphoma (LBCL), including diffuse large B-cell lymphoma (DLBCL) not otherwise specified, high-grade B-cell lymphoma, primary mediastinal large B-cell lymphoma, or follicular lymphoma grade 3B who have disease refractory to first-line chemoimmunotherapy, relapsed within 12 months of or after first-line chemoimmunotherapy, are not eligible for hematopoietic stem cell transplantation due to comorbidities or age, or have relapsed or refractory disease after ≥2 lines of...
