The FDA has approved the oral kinase inhibitor quizartinib (Vanflyta – Daiichi Sankyo) for use in combination with standard cytarabine and anthracycline induction and cytarabine consolidation, and as maintenance monotherapy following consolidation chemotherapy in adults with FLT3 internal tandem duplication (ITD)-positive, newly-diagnosed acute myeloid leukemia (AML).

Onychomycosis is caused most commonly by Trichophyton rubrum or T. mentagrophytes. About 10% of all persons worldwide and 40% of those ≥60 years old are believed to have the disease. Risk factors include older age, diabetes, poor peripheral circulation, smoking, HIV infection, psoriasis, and immunosuppression. Left untreated, onychomycosis can cause nail plate destruction, ingrown nails, and (particularly in patients with diabetes) secondary infections. Guidelines on treatment of onychomycosis have been published.

The FDA has approved afatinib (Gilotrif — Boehringer Ingelheim), an oral epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor, for first-line treatment of patients with metastatic non-small cell lung cancer (NSCLC) whose tumors have EGFR exon 19 deletions or exon 21 (L858R) substitution mutations. These mutations occur in about 10% of patients with NSCLC. Afatinib is the second EGFR inhibitor to be approved for first-line treatment of advanced lung cancer. The first was erlotinib (Tarceva), which is also approved for treatment of patients with locally advanced...

The FDA has granted accelerated approval to copanlisib (Aliqopa – Bayer), an intravenously administered phosphatidylinositol 3-kinase (PI3K) inhibitor, for treatment of adults with relapsed follicular lymphoma who have received at least two prior systemic therapies. Follicular lymphoma is a common subtype of non-Hodgkin's lymphoma. Copanlisib is the second PI3K inhibitor to be approved for this indication; idelalisib (Zydelig), which is administered orally twice daily, was the first.

The FDA has approved datopotamab deruxtecan (Datroway – Daiichi Sankyo/AstraZeneca), a trophoblast cell-surface antigen-2 (Trop-2)-directed antibody and topoisomerase inhibitor conjugate, for treatment of adults with unresectable or metastatic hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative breast cancer who received prior endocrine-based therapy and chemotherapy for unresectable or metastatic disease.

The FDA has approved the oral tyrosine kinase inhibitor ripretinib (Qinlock – Deciphera) for treatment of adults with advanced gastrointestinal stromal tumors (GISTs) who have previously received treatment with ≥3 kinase inhibitors, including imatinib (Gleevec, and generics).

The oral kinase inhibitor tucatinib (Tukysa – Seagen) has received accelerated approval from the FDA for use in combination with trastuzumab (Herceptin) for treatment of adults with RAS wild-type human epidermal growth factor receptor 2 (HER2)-positive unresectable or metastatic colorectal cancer that has progressed following treatment with fluoropyrimidine-, oxaliplatin-, and irinotecan-based chemotherapy regimens. Tucatinib was approved in 2020 for use in combination with trastuzumab and capecitabine (Xeloda, and generics) for treatment of adults with advanced unresectable or...

Talquetamab-tgvs (Talvey – Janssen), a bispecific GPRC5D-directed T-cell engager, has been granted accelerated approval by the FDA 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. Accelerated approval was based on the response rate and durability of response. Talquetamab is the first bispecific GPRC5D-directed T-cell engager to be approved in the US

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.

An extended-release formulation of carbamazepine, available since 1997 for treatment of epilepsy, has now been approved under a new name, Equetro, for acute mania and mixed episodes of bipolar disorder. Although the drug was effective in some patients for up to 6 months, it has not been approved for maintenance treatment. Carbamazepine has not been shown to be more effective than lithium or valproate, and it can cause serious adverse effects.
