Safety and efficacy of the JAK/rock inhibitor rovadicitinib in combination with the bromodomain and extra-terminal inhibitor TQB3617 in patients with myelofibrosis: A phase ib/II study (ASH 2025) - P1, P1/2, P2 | "Rovadicitinib in combination with TQB3617 was generally safe, well-tolerated, and showed clinical activityin pts with MF who were either JAKi-naïve or had a suboptimal response to JAKi treatment. This regimenmay represent a new treatment option for such patients with MF. A phase III study is currently beingplanned in pts with MF who had a suboptimal response to JAKi treatment."

BCL-2 inhibitor TQB3909 combined with JAK inhibitors in patients with intermediate- or high-risk myelofibrosis: A two-cohort, open-label, Phase ib/II, multicenter study (ASH 2025) - P1/2 | "Previous studies of BCL-2 inhibitor plus ruxolitinib (RUX) have shown improved efficacycompared to JAKi monotherapy...Palpable splenomegaly (≥5 cm below LCM) or spleen volume ≥450 cm³ (MRI/CT) was required.Pts received either RUX or rovadicitinib (ROV) combined with TQB3909 based on investigator discretion.Dose escalation of TQB3909 (100 mg, 200 mg, 300 mg QD) was first explored in the RUX cohort, followedby a 3+3 dose-escalation design in the ROV cohort (10mg, 15 mg bid)... TQB3909 combined with JAKi demonstrated meaningful clinical activity in MF pts,particularly in combination with ROV, showing spleen reduction, symptom improvement, and potentialanemia benefit. However, TQB3909+ROV is associated with hematologic toxicities, and dose optimizationis ongoing to balance efficacy and tolerability.

New molecules in the therapy of chronic graft-versus-host disease. (PubMed, Curr Opin Hematol) - "Expanding therapeutic options in cGvHD require decision-making based on organ involvement, prior therapy, and tolerability. Emerging compounds offer the potential to modulate chronic inflammation and fibrosis more precisely, supporting a move toward personalized and combinatorial approaches in advanced-line settings."

Role of ROCK2 inhibitors in the Treatment of Chronic Graft-versus-Host disease. (PubMed, Expert Opin Investig Drugs) - "This includes a review of the current and ongoing clinical data with belumosudil, and an overview of current ROCK2 inhibitors in development for cGVHD including rovadicitinib, zelasudil and GV-101. Many of the recent novel agents with unique mechanisms such as ROCK2 inhibitors (i.e. belumosudil) provide high response rates but rarely yield complete responses in cGVHD. The future of management of cGVHD will rely on investigating combination therapy upfront that may achieve deeper complete responses, developing newer preventative therapies, and advancements in biomarker detection/risk stratification for cGVHD."

RESULTS FROM PHASE IB/IIA CLINICAL STUDY OF FIRST-IN-CLASS JAK/ROCK INHIBITOR “ROVADICITINIB” PUBLISHED IN BLOOD (HKEXnews) - P1b/2 | N=45 | NCT04944043 | Sponsor: Chia Tai Tianqing Pharmaceutical Group Co., Ltd. | "A total of 44 subjects were enrolled in the study, with 29 in a 10 mg twice-daily group and 15 in a 15 mg twice-daily group. The results showed that rovadicitinib was well tolerated, with no dose-limiting toxicity at both dosages and no rovadicitinib-related adverse events leading to discontinuation....The best overall response (BOR) for the overall study population was 86.4% (95% confidence interval (CI), 72.6-94.8), with no difference between the two dosage groups. Besides, BOR achieved 72.7% (8/11) in the glucocorticoid-refractory cohort and 90.9% (30/33) in the glucocorticoid-dependent cohort. All affected organs exhibited responses regardless of any prior therapy. The failure-free survival rate for 12 months was 85.2% (95% CI, 64.5-94.3)."
