AbbVie Acquires ImmunoGen, for Approx. $10.1 Billion

AbbVie

AbbVie (NYSE: ABBV) acquired ImmunoGen (NASDAQ: IMGN), a Waltham, MA-based company developing antibody-drug conjugates (ADCs), for approx. $10.1 Billion.

The boards of directors of both companies have approved the transaction, which is expected to close in the middle of 2024, subject to ImmunoGen shareholder approval, regulatory approvals, and other customary closing conditions.  

The acquisition accelerates AbbVie’s commercial and clinical presence in the solid tumor space. Additionally, ImmunoGen’s follow-on pipeline of promising next-generation ADCs further complements AbbVie’s ADC platform and existing programs.

Led by Mark Enyedy, president and chief executive officer, ImmunoGen is developing antibody-drug conjugates (ADCs) to improve outcomes for cancer patients. Its flagship cancer therapy, ELAHERE® (mirvetuximab soravtansine-gynx), is approved for platinum-resistant ovarian cancer (PROC).

ELAHERE is a first-in-class ADC targeting folate receptor alpha (FRα) with a maytansinoid payload DM4, a potent tubulin inhibitor designed to kill the targeted cancer cells. It received U.S. Food and Drug Administration (FDA) accelerated approval in 2022 for the treatment of adult patients with FRα positive, platinum-resistant epithelial ovarian, fallopian tube, or primary peritoneal cancer, who have received one to three prior systemic treatment regimens. The positive Phase 3 results from the MIRASOL confirmatory trial will support a Marketing Authorization Application (MAA) to the European Union and a supplemental Biologic License Application (sBLA) submission to the U.S. FDA in order to gain full approval. Ongoing clinical development programs are underway to expand into earlier lines of therapy and enter other large patient segments of the ovarian market over the next 5-10 years.

ImmunoGen’s follow-on pipeline of promising next-generation ADCs expands AbbVie’s growing oncology pipeline of potentially transformative programs across multiple different solid tumors and hematologic malignancies. ImmunoGen’s Phase 1 asset, IMGN-151, is a next-generation anti-FRα ADC for ovarian cancer with the potential for expansion into other solid tumor indications. Pivekimab sunirine, currently in Phase 2, is an anti-CD123 ADC targeting blastic plasmacytoid dendritic cell neoplasm (BPDCN), a rare blood cancer, which was granted FDA breakthrough therapy designation for the treatment of relapsed/refractory BPDCN.
