Johnson & Johnson to Acquire Firefly Bio, Inc. to Expand Oncology Pipeline with Novel Degrader Antibody Conjugate Platform

NEW BRUNSWICK, N.J.--(BUSINESS WIRE)--Johnson & Johnson (NYSE: JNJ) today announced it has entered into a definitive agreement to acquire Firefly Bio, Inc., a biotechnology company advancing its proprietary Firelink™ degrader antibody conjugate (DAC) platform, for $1 billion in cash. The Firelink™ DAC platform for KRAS-driven tumors bolsters Johnson & Johnson’s oncology pipeline and ambition to develop targeted medicines for the most prevalent and hard-to-treat solid tumors with high unmet need1.

Antibody therapeutics have revolutionized the treatment of cancer through continuous innovations from monoclonal antibodies, to bi-and multi-specifics, antibody drug conjugates, and other antibody-based approaches. The Firelink™ DAC platform is a novel, innovative approach to overcome limitations of existing treatments by delivering a highly selective protein degrader to tumor cells, while avoiding healthy cells.

“KRAS has notoriously been considered an undruggable target and patients with KRAS-driven cancers continue to face limited treatment options with survival measured in months, not years,” said John Reed, M.D., Ph.D., Executive Vice President, Innovative Medicine, Research & Development, Johnson & Johnson. “We believe the proprietary Firelink™ platform will overcome the limitations of current treatments and diversify our pipeline with preclinical candidates for treating multiple types of solid tumors.”

Johnson & Johnson is at the forefront of oncology therapiesFor more than three decades, Johnson & Johnson has advanced innovative therapies to address some of the most complex cancers and improve outcomes for patients worldwide. Firefly Bio Inc.’s capabilities in emerging modalities complement Johnson & Johnson’s existing expertise in antibody engineering and accelerates the Company’s pioneering of more effective, durable treatments.

About the agreementUnder the terms of the agreement, Johnson & Johnson will acquire Firefly Bio, Inc. for $1 billion in cash. The closing of the transaction is expected to occur later this year, subject to applicable regulatory approvals and other customary closing conditions.
