London, UK & Shanghai, China – [Insert Date] – In a significant move to bolster the therapeutic landscape for non-small cell lung cancer (NSCLC), pharmaceutical giants AstraZeneca and Abbisko Therapeutics have announced a strategic collaboration to investigate the synergistic potential of Tagrisso (osimertinib) and lumipodlin (ABSK043). This landmark partnership will see the two companies jointly conduct a multicentre, open-label Phase I/II clinical trial, aiming to evaluate the safety and efficacy of this novel combination in patients with epidermal growth factor receptor (EGFR)-mutated and programmed death-ligand 1 (PD-L1) positive locally advanced or metastatic NSCLC.
The investigational new drug (IND) application for this pivotal trial received a crucial green light from China’s National Medical Products Administration (NMPA) on May 20, 2026, marking a significant step forward in the development of this promising therapeutic strategy. Under the terms of the agreement, Abbisko Therapeutics will spearhead the leadership of the clinical study, with both AstraZeneca and Abbisko sharing comprehensive responsibilities for the execution and oversight of the trial. This collaborative approach underscores a shared commitment to accelerating the delivery of innovative treatments to patients in urgent need.
This alliance brings together AstraZeneca’s established expertise in oncology, particularly with its highly successful EGFR tyrosine kinase inhibitor (TKI) Tagrisso, and Abbisko’s pioneering work in developing novel immuno-oncology agents, exemplified by its investigational oral small molecule PD-L1 inhibitor, lumipodlin. The combination of a targeted therapy that inhibits cancer cell growth driven by specific genetic mutations and an immunotherapy agent designed to unleash the body’s own immune system against cancer cells holds immense promise for overcoming treatment resistance and achieving more durable responses in NSCLC patients.
Unveiling the Therapeutic Potential: Tagrisso and Lumipodlin in Concert
Tagrisso (Osimertinib): A Pillar in EGFR-Mutated NSCLC Treatment
Tagrisso, a third-generation, irreversible EGFR-TKI developed by AstraZeneca, has revolutionized the treatment of EGFR-mutated NSCLC. Available in convenient oral formulations of 40mg and 80mg once daily, Tagrisso has already been prescribed to over one million patients worldwide. Its efficacy in targeting specific EGFR mutations, including the T790M resistance mutation, has significantly improved outcomes for a substantial segment of NSCLC patients. AstraZeneca’s commitment to Tagrisso extends beyond its current indications, with ongoing research exploring its potential across a spectrum of EGFR-mutant NSCLC subtypes and settings. The drug’s established track record of safety and efficacy makes it an ideal backbone for combination therapies aimed at further enhancing treatment benefits.
Lumipodlin (ABSK043): A Novel Oral PD-L1 Inhibitor
Lumipodlin, the investigational compound from Abbisko Therapeutics, represents a significant advancement in the field of immuno-oncology. It is an oral small molecule inhibitor designed to selectively target the PD-L1 receptor. Unlike traditional antibody-based immunotherapies that target the PD-1/PD-L1 pathway, lumipodlin is engineered to bind directly to PD-L1, promoting its internalization and subsequent degradation. This mechanism effectively blocks the interaction between PD-1 on T-cells and PD-L1 on tumor cells, thereby diminishing the immunosuppressive microenvironment and reactivating anti-tumor T-cell responses.
The development of orally bioavailable small molecule PD-1/PD-L1 inhibitors is a significant unmet need in oncology. Such agents offer the potential for improved patient convenience, easier administration, and potentially different pharmacokinetic and pharmacodynamic profiles compared to intravenous antibody therapies. Preclinical studies have demonstrated that lumipodlin exhibits anti-tumor activity comparable to approved PD-L1 antibodies, suggesting a robust therapeutic potential. Lumipodlin is currently under investigation in an ongoing Phase I study in Australia and China for patients with advanced solid tumors, providing valuable preliminary data on its safety and tolerability.
A Strategic Collaboration: Uniting Strengths for a Common Goal
The collaboration between AstraZeneca and Abbisko Therapeutics is a testament to the power of strategic alliances in driving pharmaceutical innovation. By pooling their respective strengths and expertise, the companies aim to accelerate the development and potential approval of a combination therapy that could address the persistent challenges in treating NSCLC.
Key Aspects of the Collaboration:
- Shared Clinical Trial Responsibilities: While Abbisko will lead the study, both companies will actively participate in the design, execution, and interpretation of the Phase I/II trial data. This ensures a comprehensive approach and leverages the distinct capabilities of each organization.
- Focus on a Critical Patient Population: The trial specifically targets patients with EGFR-mutated and PD-L1 positive NSCLC, a group that may benefit from the dual action of targeted therapy and immunotherapy. Understanding the interplay between these mechanisms in this specific context is crucial.
- Leveraging Existing Infrastructure and Expertise: AstraZeneca brings its extensive experience in conducting global clinical trials, regulatory affairs, and market access, while Abbisko contributes its specialized knowledge in small molecule drug development and immuno-oncology research.
- Accelerated Development Pathway: The early clearance of the IND application from the NMPA signifies a streamlined regulatory process, allowing for a faster initiation of the trial and quicker generation of critical data.

Supporting Data and Preclinical Insights
The rationale for combining Tagrisso and lumipodlin is rooted in a deep understanding of NSCLC biology and the mechanisms of action of both drugs.
EGFR Mutations and Treatment Resistance: While Tagrisso is highly effective against common EGFR mutations, resistance mechanisms can emerge, often involving alterations in downstream signaling pathways or the tumor microenvironment. The PD-1/PD-L1 axis is a known contributor to immune evasion in cancer, and its modulation could potentially overcome resistance to targeted therapies.
Preclinical Efficacy of Lumipodlin: Preclinical models have provided compelling evidence of lumipodlin’s anti-tumor activity. Its ability to selectively target PD-L1 and induce receptor internalization suggests a potent and potentially differentiated mechanism of action compared to existing immunotherapies. The absence of approved orally bioavailable PD-1/PD-L1 small molecule drugs positions lumipodlin as a potential first-in-class agent.
Synergistic Potential: The combination strategy aims to achieve a multi-pronged attack on NSCLC. Tagrisso directly targets cancer cells driven by EGFR mutations, while lumipodlin aims to unleash the patient’s immune system to identify and eliminate these cancer cells. This dual approach has the potential to:
- Enhance Efficacy: By blocking tumor growth and simultaneously stimulating anti-tumor immunity, the combination may lead to higher response rates and deeper tumor regressions.
- Overcome Resistance: The combinatorial approach could circumvent resistance mechanisms that may develop with monotherapy.
- Improve Durability of Response: A more robust and sustained anti-tumor immune response could translate into longer progression-free survival and overall survival.
