Johnson & Johnson has entered into an agreement to acquire Halda Therapeutics for approximately $3,05 billion. The acquisition gives J&J access to Halda’s “RIPTAC” platform, which is designed to selectively kill cancer cells by linking a tumor-specific protein to a protein essential for cell survival, enabling targeted treatment even in resistant tumors. Halda’s lead candidate HLD-0915 is in clinical development for metastatic castration-resistant prostate cancer.
