2023 was a big year for hematology, neurology and oncology, with the medical specialties seeing the most FDA approvals. In terms of sponsors, Pfizer had the most approvals with six total, followed by UCB and Chiesi, each with three apiece.
When looking at commercial prospects, AstraZeneca’s respiratory syncytial virus antibody Beyfortus could be the biggest blockbuster from the 2023 cohort with expected peak sales of $1.9 billion. Alzheimer’s drug Leqembi could also be a major success, making up for the tepid demand for Aduhelm, which won conditional approval in 2021. While Aduhelm’s sales have sputtered, Leqembi could see peak revenue of $4.8 billion according to analysts.
Oncology continues to be a hot specialty with the most competition among the newly approved drugs, as the FDA continues to green light new entrants in crowded target classes such as PD-1 inhibitors.
