CymaBay to be acquired by Gilead Sciences for USD 4.3 billion
An investment in CymaBay Therapeutics by both Arctic Aurora LifeScience and Biotech Select is bearing fruit today, as the liver disease specialist has agreed to be acquired by Gilead Sciences for USD 4.3 billion, or USD 32.5 per share, representing a 26.5% premium to last Friday's close, while the stock has returned 35.4% this year.
CymaBay's main asset is seladelpar, a potentially best-in-class molecule for the treatment of primary biliary cholangitis (PBC), an autoimmune disease that causes excruciating itching, among other symptoms. In PBC, the patient's immune system attacks the bile duct, causing it to become inflamed and slowly destroyed, which can ultimately lead to liver failure.
In a pivotal Phase 3 trial, seladelpar significantly improved patients' condition, with a particularly strong effect on pruritus, which has a positive impact on patients' quality of life. Based on these data, the company is awaiting the FDA's decision on the drug's approval, which is expected by 14 August this year.
Gilead has a historic presence in hepatitis and has been active in other fibrotic and inflammatory liver diseases, so the acquisition strengthens its presence in this area and has been well received by the markets.
