Over the years, Arena Pharmaceuticals made significant strides in the biotech industry, advancing its pipeline of drug candidates aimed at treating cardiovascular, autoimmune, and other diseases. The company's innovative approach and dedication to addressing unmet medical needs positioned it as a notable player in the pharmaceutical landscape.

The acquisition was completed in March 2022, with Pfizer purchasing Arena Pharmaceuticals for approximately $6.7 billion in cash. This acquisition was driven by Pfizer's interest in Arena's promising treatment candidates, particularly those targeting diseases affecting the stomach and intestines.

The acquisition marked a significant milestone in Arena Pharmaceuticals' history, highlighting its success in developing potential therapies and attracting the attention of a major industry player like Pfizer. Today, Arena Pharmaceuticals' legacy continues under Pfizer's umbrella, contributing to the advancement of innovative treatments in the pharmaceutical industry.
