First Phase III results for AstraZeneca and Daiichi Sankyo’s TROP2-directed antibody drug conjugate demonstrated statistically significant improvement in progression-free survival vs. standard chemotherapy in previously treated locally advanced or metastatic disease
Trial will continue to assess the dual primary endpoint of overall survival
LONDON, UK I July 03, 2023 I Positive high-level results from the TROPION-Lung01 Phase III trial showed datopotamab deruxtecan (Dato-DXd) demonstrated a statistically significant improvement for the dual primary endpoint of progression-free survival (PFS) compared to docetaxel, the current standard of care chemotherapy, in patients with locally advanced or metastatic non-small cell lung cancer (NSCLC) treated with at least one prior therapy.
For the dual primary endpoint of overall survival (OS), the data were not mature and an early trend was observed in favour of datopotamab deruxtecan versus docetaxel that did not meet the prespecified threshold for statistical significance at this interim analysis. The trial will continue as planned to assess OS with greater maturity. The investigators and participants will remain blinded to the results.
The safety profile of datopotamab deruxtecan was consistent with previous clinical trials with no new safety signals identified. All grade interstitial lung disease was generally consistent with prior clinical trials, with the majority being low grade. Some Grade 5 events were observed.
Datopotamab deruxtecan is a specifically engineered TROP2-directed DXd antibody drug conjugate (ADC) being jointly developed by AstraZeneca and Daiichi Sankyo.
Susan Galbraith, Executive Vice President, Oncology R&D, AstraZeneca, said: “With TROPION-Lung01, we met the dual primary endpoint of progression-free survival, challenging the entrenched standard of care in a previously treated and unselected patient population that has long deserved an alternative to chemotherapy. These first Phase III trial results from the datopotamab deruxtecan clinical programme provide compelling evidence for the potential role this TROP2-directed antibody drug conjugate can play in treating patients with lung cancer.”
Ken Takeshita, MD, Global Head, Oncology R&D, Daiichi Sankyo, said: “We are encouraged by the statistically significant results of the dual primary endpoint of progression-free survival seen with datopotamab deruxtecan and look forward to the final overall survival analysis. We plan to share these data with regulatory authorities to discuss next steps.”
More than one million people worldwide are diagnosed with advanced NSCLC each year.1,2 While immunotherapy and targeted therapies have improved outcomes in the 1st-line metastatic setting, most patients eventually experience disease progression and receive chemotherapy.3-5 For decades, chemotherapy has been the last treatment available for patients with advanced NSCLC in the absence of other treatment options and despite limited effectiveness and known side effects.3-5 TROP2 is a protein highly expressed in a large majority of lung cancers. There are currently no TROP2-directed ADCs approved for the treatment of patients with lung cancer.6-8
TROPION-Lung01 enrolled patients with and without actionable genomic alterations, such as EGFR and ALK. Patients with actionable genomic alterations were previously treated with platinum-based chemotherapy and an approved targeted therapy. Patients without actionable genomic alterations were previously treated, concurrently or sequentially, with platinum-based chemotherapy and a PD-1 or PD-L1 inhibitor.
The data will be presented at a forthcoming medical meeting and shared with health authorities.

TROPION-Lung01
TROPION-Lung01 is a global, randomised, multicentre, open-label Phase III trial evaluating the efficacy and safety of datopotamab deruxtecan (6.0 mg/kg) versus docetaxel (75 mg/m2) in patients with locally advanced or metastatic NSCLC, with or without actionable genomic alterations, treated with at least one prior therapy. Patients without actionable genomic alterations were previously treated, concurrently or sequentially, with platinum-based chemotherapy and a prior PD-1 or PD-L1 inhibitor. Patients with actionable genomic alterations were previously treated with platinum-based chemotherapy and targeted therapy as approved for their detected genomic alteration.
The dual primary endpoints of TROPION-Lung01 are PFS as assessed by blinded independent central review (BICR) and OS. Key secondary endpoints include investigator-assessed PFS, objective response rate, duration of response, time to response and disease control rate as assessed by both BICR and an investigator, and safety.
TROPION-Lung01 enrolled approximately 600 patients at sites in Asia, Europe, North America and South America. For more information visit ClinicalTrials.gov.
Datopotamab deruxtecan (Dato-DXd)
Datopotamab deruxtecan (Dato-DXd) is an investigational TROP2-directed ADC. Designed using Daiichi Sankyo’s proprietary DXd ADC technology, datopotamab deruxtecan is one of five lead ADCs in the oncology pipeline of Daiichi Sankyo, and one of the most advanced programmes in AstraZeneca’s ADC scientific platform. Datopotamab deruxtecan is comprised of a humanized anti-TROP2 IgG1 monoclonal antibody, developed in collaboration with Sapporo Medical University, attached to a number of topoisomerase I inhibitor payloads, an exatecan derivative, via tetrapeptide-based cleavable linkers.
A comprehensive development programme is underway globally with more than 12 trials evaluating the efficacy and safety of datopotamab deruxtecan across multiple TROP2-targetable tumours, including NSCLC, triple-negative breast cancer and hormone receptor-positive, HER2-low or negative breast cancer. Beyond the TROPION programme, datopotamab deruxtecan is also being evaluated in novel combinations in several ongoing trials.
In NSCLC, the TROPION-Lung07, TROPION-Lung08 and AVANZAR Phase III trials are evaluating datopotamab deruxtecan and immune checkpoint inhibitor combinations as potential 1st-line treatment options for patients with advanced or metastatic disease, a strategy informed by the results of two early trials. AstraZeneca is also researching a potential diagnostic test to help identify patients most likely to benefit from treatment with datopotamab deruxtecan.
AstraZeneca and Daiichi Sankyo collaboration
AstraZeneca and Daiichi Sankyo entered into a global collaboration to jointly develop and commercialise Enhertu in March 2019 and datopotamab deruxtecan in July 2020, except in Japan where Daiichi Sankyo maintains exclusive rights for each ADC. Daiichi Sankyo is responsible for the manufacturing and supply of Enhertu and datopotamab deruxtecan.
