The oral poly(ADP-ribose) polymerase (PARP) inhibitor olaparib (Lynparza – AstraZeneca) has now been approved by the FDA for use in combination with abiraterone (Zytiga, and others) and either prednisone or prednisolone for treatment of adults with deleterious or suspected deleterious BRCA-mutated (BRCAm) metastatic castration-resistant prostate cancer (mCRPC). Olaparib was previously approved by the FDA for treatment of adults with deleterious or suspected deleterious germline or somatic homologous recombinant repair (HRR) genemutated mCRPC who progressed on prior treatment with...

The FDA has approved osimertinib (Tagrisso – AstraZeneca), an oral kinase inhibitor, for adjuvant treatment of non-small cell lung cancer (NSCLC) after tumor resection in adults who have epidermal growth factor receptor (EGFR) exon 19 deletions or exon 21 L858R mutations. Osimertinib is the first targeted therapy to be approved in the US for this indication. The drug was previously approved for first-line treatment of adults with NSCLC with EGFR exon 19 deletions or exon 21 L858R mutations and for treatment of EGFR T790M mutation-positive NSCLC in adults whose disease progressed...

Akeega (Janssen), a fixed-dose combination of the oral poly(ADP-ribose) polymerase (PARP) inhibitor niraparib (Zejula) and the antiandrogen abiraterone acetate (Zytiga, and others), has been approved by the FDA for use in combination with prednisone for treatment of adults with deleterious or suspected deleterious BRCA-mutated (BRCAm) metastatic castration-resistant prostate cancer (mCRPC). Niraparib has been available since 2017 for treatment of epithelial ovarian, fallopian tube, or primary peritoneal cancer. Abiraterone acetate has been available since 2011 for treatment of CRPC...

Low-intensity extracorporeal shockwave therapy similar to that used to fragment kidney stones or gallstones is a new option for treatment of erectile dysfunction that is now being advertised extensively in the US. It has not been approved by the FDA for treatment of erectile dysfunction.

The FDA has authorized over-the-counter (OTC) sale of a nonmedicated alcohol-based gel (Eroxon – Futura) for treatment of erectile dysfunction (ED) in males ≥22 years old. Eroxon is the only FDA-approved OTC and topical treatment for erectile dysfunction. It is also available in the UK and the EU.

The FDA has approved two new oral formulations of testosterone undecanoate — Kyzatrex (Marius) and Tlando (Antares) — for treatment of males with a deficiency of endogenous testosterone due to conditions such as Klinefelter syndrome, orchiectomy, toxic damage from chemotherapy or alcohol, or pituitary-hypothalamic injury caused by tumors, trauma, or radiation. Jatenzo, another oral testosterone undecanoate formulation, was approved for the same indication in 2019. No testosterone products are approved for treatment of low testosterone levels due solely to...

The FDA has approved daprodustat (Jesduvroq – GSK), a hypoxia-inducible factor prolyl hydroxylase inhibitor (HIF-PHI), for oral treatment of anemia due to chronic kidney disease (CKD) in adults who have been on dialysis for at least 4 months. It is the first HIF-PHI and the first oral drug to be approved in the US for this indication.

Rozanolixizumab-noli (Rystiggo – UCB), a neonatal Fc receptor (FcRn) blocker, has been approved by the FDA for treatment of generalized myasthenia gravis in adults with anti-acetylcholine receptor (AChR) or anti-muscle-specific tyrosine kinase (MuSK) antibodies. It is the first drug to be approved for treatment of generalized myasthenia gravis in patients with anti-MuSK antibodies. Four other biologic drugs – the FcRn blocker efgartigimod alfa (Vyvgart; Vyvgart Hytrulo) and the complement inhibitors eculizumab (Soliris), ravulizumab (Ultomiris), and zilucoplan (Zilbrysq) – are...
