Ado-trastuzumab emtansine (Kadcyla – Genentech), a human epidermal growth factor receptor 2 (HER2)-targeted antibody and microtubule inhibitor conjugate, has been approved by the FDA for intravenous (IV) treatment of HER2-positive metastatic breast cancer in patients previously treated with trastuzumab (Herceptin) and a taxane. The prefix was added to the new conjugate’s name at the request of the FDA to distinguish it from trastuzumab.

Metreleptin (Myalept – Amylin), a recombinant leptin analog produced in E. coli, has been approved by the FDA to treat the complications of leptin deficiency in patients with congenital or acquired generalized lipodystrophy. It has not been approved to date for the treatment of partial lipodystrophies, including those associated with the use of protease inhibitors in patients with HIV. Metreleptin is approved in Japan for the treatment of any lipodystrophy disorder.

Olaratumab (Lartruvo – Lilly), a platelet-derived growth factor receptor alpha (PDGFR-α) blocking monoclonal antibody, has received accelerated approval from the FDA for use in combination with the anthracycline doxorubicin for first-line treatment of adults with soft-tissue sarcoma histologic subtypes considered susceptible to anthracyclines. Approval is limited to locally advanced or metastatic soft-tissue sarcomas that are not amenable to curative radiotherapy or surgery, and is contingent on verification of clinical benefit in a confirmatory phase 3 trial.

The FDA has approved setmelanotide (Imcivree – Rhythm), a subcutaneously injected melanocortin 4 (MC4) receptor agonist, for chronic weight management in patients ≥6 years old with obesity due to pro-opiomelanocortin (POMC) deficiency, proprotein subtilisin/kexin type 1 (PCSK1) deficiency, or leptin receptor (LEPR) deficiency.

Rilonacept (Arcalyst – Kiniksa), an interleukin-1 (IL-1) antagonist that has been available for years for treatment of cryopyrin-associated periodic syndromes, has now been approved by the FDA for treatment of recurrent pericarditis and prevention of further recurrences in patients ≥12 years old. It is the first drug to be approved in the US for this indication. Anakinra (Kineret), an IL-1 receptor antagonist FDA-approved for treatment of rheumatoid arthritis, has been used off-label for years for treatment of recurrent pericarditis.

The FDA has approved an over-the-counter (OTC) liquid-filled capsule formulation of aspirin (Vazalore – PLx Pharma). The manufacturer has been heavily promoting Vazalore with claims of fast, predictable absorption and antiplatelet activity and improved gastrointestinal safety compared to existing OTC aspirin formulations.

The oral kinase inhibitor alpelisib (Vijoice – Novartis) has been approved by the FDA for treatment of patients ≥2 years old with severe manifestations of PIK3CA-related overgrowth spectrum (PROS) who require systemic treatment. Alpelisib is the first drug to be approved in the US for this indication. It was also approved in 2019 as Piqray for use in combination with fulvestrant for treatment of certain types of breast cancer.
