Core Viewpoint - The approval of the clinical trial application for TQ05105 by the FDA marks a significant milestone for the company, enabling it to conduct trials in the U.S. and potentially benefit more patients, showcasing the company's innovative drug development capabilities and international strategic efforts [1][2]. Group 1: Product Development - TQ05105 (Rovastinib) is a novel JAK/ROCK inhibitor developed by the company, aimed at treating chronic graft-versus-host disease (cGVHD), a major complication post-transplantation [1]. - The drug effectively inhibits JAK family kinase activity and ROCK kinase activity, suppressing the JAK/STAT signaling pathway and exhibiting anti-tumor activity while selectively inhibiting ROCK2 to restore immune balance [1]. - Previous studies in China indicated that TQ05105 has a 90.9% objective response rate in cGVHD patients, with 88.6% of patients reducing steroid dosage [1]. Group 2: Strategic Implications - The FDA's approval is seen as a testament to the company's exceptional drug innovation capabilities and a proactive step in its internationalization strategy [2]. - The company is accelerating multiple combination studies for TQ05105, including trials with BET inhibitors or BCL-2 inhibitors for treating high-risk myelofibrosis, with preliminary results appearing positive [2].
