Efficacy and safety results of TQB3909,a novel BCL-2 inhibitor, in combination with azacitidine for patients with myeloid malignancies (ASH 2025) - P1/2 | "The median time to first CRc (mTTCRc) response was 0.95 months (95% CI, 0.92 to 1.97).The median duration of CRc was not reached (95% CI, 3.91 to NR) .In the 400mg cohort (n=25), ORR andCRc were 88% and 76%, respectively; mTTCRc was 0.95 months ((95% CI, 0.92 to 1.38); the medianduration of CRc was not reached (95% CI, 2.86 to NR); median OS was not reached (95% CI, 3.19 to NR).Among 9 pts with R/R AML treated with TQB3909+AZA, ORR and CRc were 75% and 62.5%, respectively.ConclusionsThis new BCL-2 inhibitor TQB3909 combined with AZA demonstrated significant efficacy in pts withelderly/unfit TN and R/R AML. No significant new safety findings were observed."

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.
