Sanofi Completes Acquisition of Inhibrx, Inc.

Sanofi announced the completion of its acquisition of Inhibrx, Inc. The acquisition adds SAR447537 (formerly INBRX-101) to Sanofi’s rare disease pipeline, underscoring the company’s commitment to pursuing differentiated and potential best-in-class medicines that build upon our existing strengths and capabilities.

SAR447537 is a human recombinant protein that holds the promise of allowing alpha-1 antitrypsin deficiency (AATD) patients to achieve normalization of serum AAT levels with less frequent (monthly vs. weekly) dosing. AATD is an inherited rare disease characterized by low levels of AAT protein, predominantly affecting the lung with progressive deterioration of the tissue. SAR447537 may help to reduce inflammation and prevent further deterioration of lung function in affected individuals.

The former holders of shares of Inhibrx common stock voted to approve the acquisition at a special meeting of stockholders on May 24, 2024. Upon the closing of the acquisition, former shareholders of Inhibrx became entitled to receive $30.00 per share in cash, which represents a total equity value of approximately $1.7 billion (on a fully diluted basis), as well as one contingent value right per share to receive $5.00 upon the achievement of a regulatory milestone.

Sanofi completed its acquisition of Inhibrx through the merger of an indirect, wholly-owned subsidiary of Sanofi with and into Inhibrx, with Inhibrx continuing as the surviving corporation and becoming an indirect, wholly-owned subsidiary of Sanofi.
