Merck & Co Inc’s $10 billion acquisition of Verona Pharma Plc is set to close in the 2025 fourth quarter marking one of the larger transactions in the biopharma space in recent times. The deal will give Merck a recently approved asset for chronic obstructive pulmonary disease (COPD) that is on a promising trajectory. When Merck announced its offer on 9 July, some share analysts were already predicting blockbuster status for the asset, Ohtuvayre (ensifentrine), which was approved by the US Food and Drug Administration on 26 June 2024.
