The FDA has approved the neoadjuvant (preoperative) use of pertuzumab (Perjeta – Genentech) in combination with trastuzumab (Herceptin) and docetaxel (Taxotere, and generics) for treatment of locally advanced, inflammatory, or early-stage HER2 (human epidermal growth factor receptor 2)-positive breast cancer patients with tumors >2 cm in diameter or node-positive disease. Pertuzumab in combination with trastuzumab and docetaxel was approved earlier for treatment of HER2-positive metastatic breast cancer. Pertuzumab is the first drug to be approved for neoadjuvant treatment of...

A reader asked whether healthcare providers should avoid prescribing the angiotensin receptor blocker (ARB) olmesartan medoxomil (Benicar, and others) because it can cause severe GI adverse effects.In 2013, the FDA warned that olmesartan can cause sprue-like enteropathy, a condition characterized by intestinal villous atrophy, severe chronic diarrhea, and significant unintended weight loss. The warning was based on 23 cases of serious sprue-like enteropathy associated with use of olmesartan, some occurring years after starting the drug. All patients improved after stopping olmesartan; 10 had a...

The FDA has approved the oral tyrosine kinase inhibitor neratinib (Nerlynx – Puma Biotechnology) for extended adjuvant treatment of adults with early-stage, human epidermal growth factor receptor 2 (HER2)-positive breast cancer, following adjuvant trastuzumab (Herceptin)-based therapy. HER2 is overexpressed in about 20% of breast cancers. Up to 30% of early-stage, HER2-positive breast cancer cases treated with trastuzumab-based adjuvant therapy recur.

The FDA has approved lutetium lu 177 vipivotide tetraxetan (Pluvicto – Novartis) for treatment of prostate-specific membrane antigen (PSMA)-positive metastatic castration-resistant prostate cancer (mCRPC) in adults previously treated with androgen receptor (AR) pathway inhibitors and taxane-based chemotherapy.

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...

The oral poly(ADP-ribose) polymerase (PARP) inhibitor talazoparib (Talzenna – Pfizer) has been approved by the FDA for use in combination with the androgen receptor blocker enzalutamide (Xtandi) for treatment of adults with homologous recombination repair (HRR) gene-mutated metastatic castration-resistant prostate cancer (mCRPC). The drug has been available since 2018 for treatment of deleterious or suspected deleterious germline BRCA-mutated (gBRCAm), HER2-negative locally advanced or metastatic breast cancer.

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...

The FDA has required a new warning in the labels of the recombinant respiratory syncytial virus (RSV) vaccines Arexvy (GSK) and Abrysvo (Pfizer) about an increased risk of Guillain-Barré syndrome (GBS) within 42 days of administration of either vaccine. Both vaccines are FDA-approved to prevent lower respiratory tract disease (LRTD) caused by RSV in adults.Abrysvo is also approved for use in pregnant women at 32-36 weeks' gestation to prevent RSV-associated LRTD in their infants from birth through 6 months of age.

Clevidipine (Cleviprex - The Medicines Company), a dihydropyridine calcium channel blocker (CCB), has been approved by the FDA for intravenous (IV) use in lowering high blood pressure. It is the second IV CCB to be marketed in the US; nicardipine has been available in an IV formulation (Cardene IV) for more than 10 years. Like IV nicardipine, clevidipine will probably be used mainly for urgent treatment of hypertension in intensive care units, operating rooms and emergency departments.

Rufinamide (Banzel - Eisai), a triazole derivative structurally unrelated to other marketed antiepileptic drugs (AEDs), has been approved by the FDA for treatment of seizures associated with Lennox-Gastaut syndrome (LGS) in patients ≥4 years old.
