The development follows an agreement in April 2025 in which Novartis signed an agreement to acquire Regulus and its oligonucleotide therapy, farabursen.
The transaction received unanimous approval from both companies’ boards and includes a significant premium over recent stock prices for Regulus shareholders as well as contingent value rights (CVRs) tied to future regulatory successes.
56.4 million shares were tendered by the expiration date of 24 June 2025.
Farabursen is a next-generation oligonucleotide targeting miR-17 designed to combat autosomal dominant polycystic kidney disease (ADPKD).
