The use of intracoronary stents in angioplasty procedures has improved both short- and long-term success rates. In recent years, drug-eluting stents (DESs) have largely replaced bare-metal stents (BMSs).

Apremilast (Otezla – Celgene), an oral phosphodiesterase type-4 (PDE4) inhibitor, has been approved by the FDA for treatment of active psoriatic arthritis in adults. It is the fi rst PDE4 inhibitor to be approved for this indication.

Eteplirsen (Exondys 51 – Sarepta), an antisense oligonucleotide, has received accelerated approval from the FDA for treatment of Duchenne muscular dystrophy (DMD) in patients who have a mutation of the dystrophin gene that is amenable to exon 51 skipping. It is the first drug to be approved for treatment of DMD.

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 an auto-injector formulation of testosterone enanthate (Xyosted – Antares Pharma) for once-weekly subcutaneous self-administration in adult males with conditions associated with a deficiency or absence of endogenous testosterone. It is the first subcutaneous formulation of testosterone to be approved by the FDA. Xyosted is contraindicated for treatment of low testosterone levels associated with aging.

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 has approved cantharidin 0.7% solution (Ycanth – Verrica) for topical treatment of molluscum contagiosum in patients ≥2 years old. Ycanth was the first drug to be approved in the US for this indication. A 10.3% gel formulation of berdazimer (Zelsuvmi), a nitric oxide-releasing agent, has also been approved by the FDA for treatment of molluscum contagiosum (in patients ≥1 year old); it will be reviewed in a future issue.

Taletrectinib (Ibtrozi – Nuvation Bio), an oral kinase inhibitor, has been approved by the FDA for treatment of locally advanced or metastatic ROS1-positive non-small cell lung cancer (NSCLC) in adults. It is the fourth oral kinase inhibitor to be approved in the US for this indication; crizotinib (Xalkori), entrectinib (Rozlytrek), and repotrectinib (Augtyro) were approved earlier.

Bemotrizinol (bis-ethylhexyloxyphenol methoxyphenol triazine), a broad-spectrum, organic ultraviolet (UV) filter that has been available in Europe since 2000, is the first new active ingredient with broad availability to be added to the FDA's OTC sunscreen monograph in more than 25 years, and the first organic UV filter to be generally recognized as safe and effective (GRASE). Data with other organic UV filters are insufficient for a GRASE designation.

Recombinant interferon alfa-2b (Intron A - Schering) was recently approved by the US Food and Drug Administration (FDA) for intralesional treatment of genital warts (condylomata acuminata). Interferon was previously available only for treatment of hairy-cell leukemia (Medical Letter, 28:78, 1986).
