The FDA has approved tisagenlecleucel (Kymriah — Novartis), an individualized, genetically-modified cellular product, for treatment of relapsed or refractory B-cell precursor acute lymphoblastic leukemia (ALL) in patients ≤25 years old. The patient's own T cells are genetically modified to express chimeric antigen receptors (CAR) and then reinfused. Kymriah is the first CAR T-cell immunotherapy to become available in the US. A CAR T-cell product for B-cell non-Hodgkin's lymphoma is expected to be approved soon.

The FDA has approved axicabtagene ciloleucel (Yescarta – Kite) for treatment of adults with relapsed or refractory CD19+ large B-cell lymphoma after ≥2 lines of systemic therapy. Yescarta is an individualized cellular product prepared from the patient's own T cells, which are genetically modified to express chimeric antigen receptors (CAR) and then infused back into the patient. It is the second CAR T-cell immunotherapy to become available in the US. Tisagenlecleucel (Kymriah), a CAR T-cell product previously approved for treatment of relapsed or refractory B-cell...

Quzyttir (TerSera), an IV formulation of the second-generation H1-antihistamine cetirizine, has been approved by the FDA for treatment of acute urticaria in patients ≥6 months old.

The FDA has approved a higher-dose injectable formulation of the opioid antagonist naloxone (Zimhi – Adamis) for emergency treatment of opioid overdose. A single IM or SC injection of the new formulation delivers 5 mg of naloxone; injectable formulations that deliver 0.4 mg or 2 mg of the drug have been available for years. Naloxone is also available in intranasal formulations for the same indication (see Table 1).

The FDA has approved idecabtagene vicleucel (Abecma – BMS), a B-cell maturation antigen (BCMA)-directed genetically-modified cellular product, for treatment of relapsed or refractory multiple myeloma in adults who received ≥4 prior lines of therapy, including a proteasome inhibitor, an immunomodulatory drug, and an anti-CD38 monoclonal antibody. Abecma is an individualized cellular product prepared from the patient’s own T cells, which are genetically modified to express chimeric antigen receptors (CAR) and then infused back into the patient. Ciltacabtagene autoleucel...

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.
