Immutep Chief Executive Officer, Marc Voigt, said, "The excellent pace of enrolment globally in the TACTI-004 trial speaks to the promise of efti and the need for more efficacious therapies in the first line setting for patients with advanced/metastatic non-small cell lung cancer. Our team continues to work hard to bring this innovative cancer immunotherapy to market and looks forward to delivering on additional important upcoming milestones ahead, including the futility analysis in the first quarter and completing patient enrolment in the third quarter this year."

The combination of efti with KEYTRUDA and chemotherapy has the potential to establish a new standard of care in 1L NSCLC, one of the largest and deadliest indications in oncology, by expanding the number of patients who respond to anti-PD-1 therapy, across all PD-L1 expression levels, along with enhancing clinical outcomes and extending patients’ survival.

The registrational TACTI-004 Phase III has enrolled 378 patients globally and enrolment continues its robust pace. Additionally, over 140 clinical sites are now activated across 27 countries. The futility analysis and completion of patient enrolment remain on track for the first quarter and the third quarter of CY2026, respectively.

KEYTRUDA is a registered trademark of Merck Sharp & Dohme LLC, a subsidiary of Merck & Co., Inc., Rahway, NJ, USA.

About TACTI-004
TACTI-004 (Two ACTive Immunotherapies) is a randomised, double-blind, controlled Phase III study evaluating eftilagimod alfa (efti), a first-in-class MHC Class II agonist, in combination with MSD’s (Merck & Co., Inc., Rahway, NJ, USA) anti-PD-1 therapy, KEYTRUDA (pembrolizumab), and chemotherapy as first line therapy for patients with advanced or metastatic non-small cell lung cancer with no EGFR, ALK or ROS1 genomic tumour aberrations. The global trial will enrol approximately 756 patients regardless of PD-L1 expression and with non-squamous or squamous tumours at over 150 clinical sites in over 25 countries. Patients will be randomised 1:1 to receive either efti in combination with pembrolizumab and chemotherapy in the treatment arm or pembrolizumab in combination with chemotherapy and placebo in the control arm. The study’s dual primary endpoints are progression-free survival and overall survival.

About Eftilagimod Alfa (Efti)
Efti is a novel immunotherapy that directly activates antigen-presenting cells or APCs (e.g. dendritic cells, monocytes) via the MHC Class II pathway to fight cancer. As an MHC Class II agonist, its activation of APCs engages the adaptive and innate immune system to initiate a broad anti-cancer immune response. This includes priming and activating cytotoxic T cells as well as generating important co-stimulatory signals & cytokines that further boost the immune system’s ability to combat cancer.

Efti is under evaluation for a variety of solid tumours including non-small cell lung cancer (NSCLC) in a pivotal Phase III trial called TACTI-004 (KEYNOTE-F91), as well as head and neck squamous cell carcinoma (HNSCC), soft tissue sarcoma, and breast cancer. Its favourable safety profile enables various combinations like with anti-PD-[L]1 immunotherapy, radiotherapy, and/or chemotherapy. Efti has received Fast Track designation in first line HNSCC and in first line NSCLC from the United States Food and Drug Administration (FDA).

On February 5, 2026 Ascentage Pharma Group International (NASDAQ: AAPG; HKEX: 6855), a global, commercial stage, integrated biopharmaceutical company engaged in the discovery, development and commercialization of novel, differentiated therapies to address unmet medical needs in cancer, reported that its novel next-generation Bruton’s tyrosine kinase (BTK)-targeted protein degrader, APG-3288, has received investigational new drug (IND) application clearance from the China Center for Drug Evaluation (CDE) and is poised to enter a clinical study in patients with relapsed/refractory hematologic malignancies. This IND clearance from the China CDE, which came shortly after the IND was cleared by the U.S. Food and Drug Administration (FDA), ushers in a new phase in the multicenter clinical development of APG-3288 and highlights Ascentage Pharma’s robust global development capabilities in the field of targeted protein degradation.

Ascentage Pharma will be conducting a multicenter, open-label Phase I study designed to evaluate the safety, tolerability, pharmacokinetic (PK) profile, and preliminary efficacy of APG-3288 in patients with relapsed/refractory hematologic malignancies.

BTK is a key kinase in the B-cell receptor (BCR) signaling pathway and plays a central role in the activation, proliferation, and survival of B-cells. Aberrant BTK activation is closely associated with the initiation and progression of multiple B-cell malignancies such as B-cell lymphoma (including diffuse large B-cell lymphoma, mantle cell lymphoma, and follicular lymphoma), chronic lymphocytic leukemia (CLL), and Waldenström’s macroglobulinemia (WM)1. BTK inhibitors have drastically improved treatment outcomes for patients with B-cell malignancies. However, BTK mutations and remodeling of signaling pathways often lead to acquired resistance during prolonged treatment. There remains an urgent clinical need for new drugs promising novel mechanisms of action.

APG-3288 is a highly potent and selective BTK degrader developed utilizing Ascentage Pharma’s proprietary proteolysis-targeting chimera (PROTAC) technology platform. This candidate induces the formation of a ternary complex consisting of the BTK target, the PROTAC, and the Cereblon E3 ubiquitin ligase, leading to proteasome-mediated degradation of the BTK target. Unlike conventional BTK inhibitors, APG-3288 is designed to act through degradation rather than inhibition, inducing rapid, potent, highly selective, and sustained degradation of both wild-type BTK and multiple BTK mutants associated with resistance to existing BTK inhibitors. Critically, this approach blocks the BCR-BTK signaling axis at its source, thereby overcoming resistance to BTK inhibitors and potentially providing a novel and differentiated therapeutic strategy for BTK-targeted treatment3.

As a company focused on developing innovative drugs for cancer treatment, Ascentage Pharma has dedicated many years building a strong presence in the field of hematologic malignancies with a portfolio that includes Olverembatinib and Lisaftoclax, two products that have already been approved in China. This IND clearance for APG-3288 in China will further strengthen the Company’s pipeline in hematologic malignancies and lay a strong foundation for potential combinations with other key assets within the pipeline.

Yifan Zhai, M.D., Ph.D., Chief Medical Officer of Ascentage Pharma, said, "After receiving IND clearances for APG-3288 from the U.S. FDA and then the China CDE, we have reached a significant milestone in the field of targeted protein degradation, taking another major step forward with our global innovation strategy. There is considerable unmet clinical need in patients with hematologic malignancies, particularly those drug-resistant patients who desperately lack treatment options. We will expeditiously advance this global clinical development program for APG-3288 and actively explore its combinatory potential in efforts to bring this innovative therapeutic to patients in China and around the world as soon as possible."

*APG-3288 is currently under investigation and has not been approved by the U.S. FDA

The assay is available to detect key AML-associated KMT2A rearrangements, which account for the vast majority of KMT2A fusion partners in AML1 and those most commonly targeted in menin-inhibitor clinical development programs. Later this year, the assay will be enhanced with four additional KMT2A rearrangements which are frequently found in acute lymphocytic leukemia (ALL), expanding its utility across leukemias.

The LeukoStrat KMT2A + MRD Assay accurately identifies and quantifies common KMT2A rearrangements that drive KMT2A-translocated acute leukemias, offering translational researchers and biopharmaceutical partners a critical tool to assess MRD and to evaluate therapeutic response. With unprecedented sensitivity down to 0.005% (5×10-5) and precise quantitation through normalization against a control gene, the assay enables far more rapid turnaround time and more sensitive detection of low-level KMT2A rearrangements that traditional cytogenetics and FISH methods miss. The LeukoStrat KMT2A + MRD Assay and Software streamline both initial screening and longitudinal MRD monitoring from a single workflow, facilitating efficient implementation both in research laboratories and as a service supporting clinical research.

"Invivoscribe is setting a new standard for how researchers and biopharmaceutical partners can identify, monitor and understand disease response," said Jeff Miller, CEO and CSO at Invivoscribe. "Our LeukoStrat KMT2A + MRD Assay provides partners with a powerful tool for exploratory and pivotal analyses in menin-inhibitor trials, offering precise insights into subject response throughout treatment. This assay builds on our international reputation as the ideal partner for pharmaceuticals looking to accelerate KMT2A trials using MRD as a surrogate endpoint and for companion diagnostic development as these therapies advance toward approval."

The assay integrates with LeukoStrat KMT2A + MRD Software for rapid, objective analysis, enabling labs and biopharmaceutical partners to unlock complex molecular insights. When paired with Invivoscribe’s globally standardized LabPMM network and regulatory expertise, it supports the full development pathway from early-phase trials through CDx validation and commercialization.

For a comprehensive approach to therapy development, biopharmaceutical partners can combine the LeukoStrat KMT2A + MRD Assay for treatment monitoring with Invivoscribe’s established myeloid portfolio of IVDR and research use only LeukoStrat CDx and MRD assays, including prognostic biomarkers such as FLT3 and NPM1.2,3,4,5 Invivoscribe’s proven track record in companion diagnostics (CDx) development and successful global regulatory submissions positions the company as a trusted strategic partner for menin-inhibitor programs progressing toward approval.
