Olutasidenib (Rezlidhia – Rigel), an oral isocitrate dehydrogenase-1 (IDH1) inhibitor, has been approved by the FDA for treatment of relapsed or refractory acute myeloid leukemia (AML) in adults with a susceptible IDH1 mutation. It is the second drug that targets cancer metabolism to be approved for this indication; ivosidenib (Tibsovo) was approved in 2022.

The oral cyclin-dependent kinase (CDK) 4/6 inhibitor abemaciclib (Verzenio – Lilly) has been approved by the FDA for use in combination with endocrine therapy (tamoxifen or an aromatase inhibitor) for adjuvant treatment of patients with hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative, node-positive, early breast cancer at high risk of recurrence.1It was previously approved for the same indication, but patients were also required to have a Ki-67 score ≥20%. About 70% of all breast cancers are HR-positive and HER2-negative. Ki-67 is a...

The FDA has granted regular approval to the oral kinase inhibitor capmatinib (Tabrecta – Novartis) for treatment of metastatic non-small cell lung cancer (NSCLC) in adults whose tumors have a mutation that leads to mesenchymal-epithelial transition (MET) exon 14 skipping. MET exon 14 skipping mutations occur in 3-4% of NSCLC cases. The drug received accelerated approval for the same indication in 2020 based on initial overall response rates and duration of response.

The oral kinase inhibitor pemigatinib (Pemazyre – Incyte) has been approved by the FDA for treatment of adults with relapsed or refractory myeloid/lymphoid neoplasms (MLNs) with fibroblast growth factor receptor 1 (FGFR1) rearrangements. It is the first targeted therapy to be approved in the US for this indication. The drug received accelerated approval from the FDA in 2020 for treatment of adults with previously treated, unresectable, locally advanced or metastatic cholangiocarcinoma with FGFR2 fusions or other rearrangements.

Eflornithine (Iwilfin – US WorldMeds), an oral ornithine decarboxylase inhibitor, has been approved by the FDA to reduce the risk of relapse in children and with high-risk neuroblastoma who had at least a partial response to prior multiagent, multimodality therapy, including anti-GD2 immunotherapy. About 40-50% of neuroblastoma cases are classified as high-risk and they account for ~15% of all pediatric cancer deaths. Eflornithine is the first drug to be approved to reduce the risk of relapse in children with high-risk neuroblastoma. Eflornithine was previously available in the US...

Cosibelimab (Unloxcyt – Checkpoint Therapeutics), a programmed death ligand-1 (PD-L1) blocking antibody, has been approved by the FDA for treatment of locally advanced or metastatic cutaneous squamous cell carcinoma in adults who are not candidates for curative surgery or radiation. It is the first PD-L1 inhibitor to be approved in the US for this indication. The PD-1 inhibitors pembrolizumab (Keytruda) and cemiplimab (Libtayo) are also approved for treatment of cutaneous squamous cell carcinoma.

The tissue plasminogen activator (tPA) tenecteplase (TNKase – Genentech) has been approved by the FDA for treatment of acute ischemic stroke in adults. It is the second tPA to be approved in the US for this indication; alteplase (Activase) was approved in 1996. Tenecteplase was approved in 2000 to reduce the risk of death associated with acute ST-elevation myocardial infarction (STEMI).

Zusduri (UroGen), a mitomycin-based solution for intravesical instillation, has been approved by the FDA for treatment of recurrent low-grade intermediate-risk nonmuscle invasive bladder cancer (NMIBC) in adults. It is the first drug to be approved in the US for this indication. Mitomycin has been available for years for treatment of various malignancies.

Misoprostol (Cytotec - Searle), a synthetic methyl analog of prostaglandin E1, was recently approved by the US Food and Drug Administration for prevention of gastric ulcers in high-risk patients taking nonsteroidal anti-inflammatory drugs (NSAIDs). In other countries, the drug is also marketed for treatment of idiopathic peptic ulcers unrelated to NSAIDs.

Desmopressin acetate (DDAVP -Rorer), a synthetic analog of the natural human antidiuretic hormone arginine vasopressin, was recently approved by the US Food and Drug Administration for treatment of primary nocturnal enuresis. DDAVP Nasal Spray, which is similar to an intranasal solution that has been available in the USA for treatment of central diabetes insipidus (Medical Letter, 20:26, 1978), will be used for the new indication.
