On 5 February 2024, Rani Therapeutics published positive topline results from its phase I clinical trial regarding RT-111, a RaniPill® capsule containing Celltrion’s ustekinumab biosimilar, CT-P43 (biosimilar to Janssen’s Stelara®). The study shows that RT-111 was well-tolerated and delivered ustekinumab with high bioavailability.
In June 2023, Rani Therapeutics announced that it expanded its partnership with Celltrion to develop an orally administered adalimumab biosimilar (RT-105), following their earlier collaboration on ustekinumab (CT-P43).
