Ascentage Pharma (NASDAQ: AAPG) presented four-year follow-up data from a randomized registrational Phase II trial of olverembatinib in TKI-resistant/intolerant chronic-phase CML (CML-CP) at ASH 2025. The olverembatinib arm showed median event-free survival (EFS) 21.2 months versus 2.9 months for investigator’s choice BAT (P < 0.0001). In patients without T315I, EFS was 11.9 vs. 3.1 months (P = 0.0159). Response rates favored olverembatinib (CHR 85% vs 35%; CCyR 38% vs 19%; MMR 30% vs 8%). Safety was described as favorable with 7% vascular occlusion and grade ≥3 hematologic toxicities reported. Olverembatinib is approved in China and covered by NRDL; global rights are subject to a Takeda option.
Ascentage Pharma (NASDAQ: AAPG) reported Phase Ib/II data for lisaftoclax (APG-2575) plus azacitidine presented at ASH 2025 on Dec 6, 2025. In a 103-patient study the combination showed a 31.8% ORR in venetoclax–exposed relapsed/refractory AML/MPAL (7/22) and an 80.0% ORR in newly diagnosed high‑risk MDS/CMML (12/15). No dose‑limiting toxicities were observed across dose‑escalation and expansion. Median overall survival was reported as 7.6 months for R/R AML/MPAL and 11.3 months for R/R HR MDS/CMML; median OS was not reached in ND HR MDS/CMML. Common grade ≥3 TEAEs included neutropenia (41.7%) and febrile neutropenia (35.0%).
Ascentage Pharma (NASDAQ: AAPG) presented registrational Phase II China data for lisaftoclax (APG-2575) at ASH 2025 showing durable efficacy in BTKi‑refractory relapsed/refractory CLL/SLL.
Among 77 enrolled patients (high‑risk enrichment: 42.9% complex karyotype, 39% del(17p)/TP53), lisaftoclax achieved an IRC‑confirmed ORR 62.5% and median PFS of 23.89 months (median follow‑up 22.01 months). MRD negativity was 21.8% in peripheral blood and 54.5% in bone marrow (n=11). Safety showed manageable profile with frequent grade ≥3 hematologic toxicities; no tumor lysis syndrome or treatment‑related deaths were reported. The data supported China NMPA approval in July 2025.
Ascentage Pharma (NASDAQ: AAPG) announced that the US FDA and the EMA cleared a global registrational Phase III study (POLARIS-1; NCT06051409) of olverembatinib plus chemotherapy for newly diagnosed Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph+ ALL).
The POLARIS-1 trial is a randomized, open-label, global study already initiated in China after CDE clearance in 2023 and is simultaneously enrolling across multiple countries to accelerate registration in the US and Europe. An ASH 2025 abstract reported ~65% MRD-negativity and molecular MRD-negative CR rates after three cycles and described a favorable safety profile. Olverembatinib is China-approved for drug-resistant CML, covered by the China NRDL, and is subject to an exclusive option agreement with Takeda (June 14, 2024). The drug is not yet FDA-approved in the US.

Ascentage Pharma (NASDAQ:AAPG) published Phase Ib data for olverembatinib in Signal Transduction and Targeted Therapy reporting activity in SDH-deficient GIST.
