Sevelamer carbonate (Renvela – Genzyme), a buffered form of the anion-exchange resin sevelamer hydrochloride (Renagel – Genzyme),1 has been approved by the FDA for use in patients with chronic kidney disease on dialysis. According to the manufacturer, Renvela will replace Renagel, which has been shown to induce or exacerbate metabolic acidosis in patients on dialysis. Two randomized, crossover studies found the two sevelamer salts equivalent in their ability to lower serum phosphate.2,3 Patients taking the carbonate had higher serum bicarbonate concentrations and fewer gastrointestinal...

The FDA has approved abiraterone acetate (Zytiga – Centocor Ortho Biotech) for oral treatment, in combination with prednisone, of metastatic castration-resistant prostate cancer in patients previously treated with docetaxel (Taxotere, and others). It is the first oral drug approved for this indication. Zytiga will compete with cabazitaxel (Jevtana) and sipuleucel-T (Provenge).

Efgartigimod alfa-fcab (Vyvgart – Argenx), a first-in-class neonatal Fc receptor (FcRn) antagonist, has been approved by the FDA for IV treatment of generalized myasthenia gravis in adults who are anti-acetylcholine receptor (AChR) antibody positive. The IV complement inhibitor eculizumab (Soliris) was approved for the same indication in 2017.

The oral kinase inhibitor futibatinib (Lytgobi – Taiho) has received accelerated approval from the FDA for treatment of adults with previously treated, unresectable, locally advanced or metastatic intrahepatic cholangiocarcinoma with fibroblast growth factor receptor 2 (FGFR2) fusions or other rearrangements. Accelerated approval was based on the overall response rate and duration of response. Futibatinib is the second drug to be approved for this indication; pemigatinib (Pemazyre) was approved earlier.

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.

Revumenib (Revuforj – Syndax), an oral menin inhibitor, has been approved by the FDA for treatment of relapsed or refractory acute leukemia in patients ≥1 year old with a lysine methyltransferase 2A gene (KMT2A) translocation. It is the first menin inhibitor to be approved in the US.

Many nitrates, beta-blockers, and calcium-channel blockers have now been approved by the US Food and Drug Administration for treatment of stable angina pectoris. The table beginning on page 112 lists the individual drugs, their dosage, and their cost.

The FDA has approved nivolumab (Opdivo – BMS), an IV programmed death receptor-1 (PD-1) blocking antibody, for treatment of unresectable or metastatic melanoma that has progressed following treatment with ipilimumab (and a BRAF inhibitor in patients who are BRAF V600 mutation positive) and for treatment of metastatic squamous non-small cell lung cancer (NSCLC) that has progressed on or after platinum-based chemotherapy. It is the second PD-1 inhibitor to be marketed in the US after pembrolizumab (Keytruda), and the first to be approved for treatment of NSCLC.

Cerebral arterial spasm frequently causes ischemic neurological damage after subarachnoid hemorrhage from a ruptured intracranial aneurysm. Nimodipine (Nimotop - Miles), a 1,4-dihydropyridine calcium-entry blocker, was recently approved by the US Food and Drug Administration (FDA) for oral treatment of such patients; an intravenous preparation is available only for investigational use.

Bupropion (Wellbutrin - Burroughs Wellcome) was recently marketed in the USA for treatment of depression. First approved by the Food and Drug Administration in late 1985, the drug was withdrawn from the market in early 1986 because of a high incidence of seizures in one study.
