Rumors of AstraZeneca Takeover

NEW YORK, March 12 (Reuters) - Biotechnology company Abivax on Thursday dismissed a report by French media publication La Lettre saying it had granted AstraZeneca exclusive access to confidential information until March 23 to allow the British drugmaker to formalize a takeover offer.

Official Denial from Abivax

"We deny the information, these are unfounded rumors," a spokesperson said.

Market Reaction and Previous Takeover Stories

Impact on Abivax Shares

Abivax shares were up as much as 17% earlier on Thursday after the initial report, but pared gains through the day, with the decline accelerating after the spokesperson's denial. The shares were last up 2.8%.

History of Denials

The French biotech has previously denied takeover stories by the French media. In January, Abivax Chief Executive Marc de Garidel dismissed another report by La Lettre that his company was an acquisition target of Eli Lilly.

Investor Interest and Acquisition Talks

Investors looking to profit from Abivax's fluctuating stock price have encouraged acquisition talks over the past months.

Abivax’s Business Focus and Future Outlook

Therapeutic Focus

The French clinical‑stage company focuses on treatments for chronic inflammatory diseases.

Upcoming Data and Acquisition Potential

Abivax is expected to report in late June initial Phase 3 maintenance data for obefazimod in ulcerative colitis. If successful, this would significantly reduce the risk in investing in the company and make it a safer, but likely more expensive, target for acquisition.

Key Takeaways

  • Abivax refutes French media claims that AstraZeneca was granted exclusive access to confidential data for a takeover: spokesperson calls them “unfounded rumors.”
  • Speculation about a possible acquisition by Eli Lilly also circulated after strong Phase III trial results for obefazimod, but both the French finance ministry and company dismissed these reports.
  • Abivax’s market appeal stems from its ulcerative colitis candidate obefazimod, whose Phase III success has significantly boosted investor interest and price targets.
