Datopotamab deruxtecan plus Imfinzi showed promising clinical activity in the first-line advanced non-small cell lung cancer setting in TROPION-Lung04 Phase Ib trial



AstraZeneca and Daiichi Sankyo’s datopotamab deruxtecan plus Imfinzi with or without chemotherapy demonstrated objective response rates of 77% and 50% and disease control rates of 92% and 93%, respectively. Three ongoing pivotal trials are evaluating datopotamab deruxtecan and immune checkpoint inhibitor combinations in 1st-line advanced non-small cell lung cancer.

Initial results from the TROPION-Lung04 Phase Ib trial showed that datopotamab deruxtecan (Dato-DXd) in combination with Imfinzi (durvalumab), an anti-PD-L1 therapy, with or without carboplatin demonstrated encouraging responses and no new safety signals in patients with previously untreated advanced or metastatic non-small cell lung cancer (NSCLC) without actionable genomic alterations.

These data were presented today in a late-breaking oral presentation (#OA05.06) at the International Association for the Study of Lung Cancer (IASLC) 2023 World Conference on Lung Cancer (WCLC).

Datopotamab deruxtecan is a specifically engineered TROP2-directed DXd antibody drug conjugate (ADC) being jointly developed by AstraZeneca and Daiichi Sankyo.

More than one million people worldwide are diagnosed with advanced NSCLC each year.1,2 While 1st-line treatment with immune checkpoint inhibitors with or without chemotherapy has improved outcomes for patients with NSCLC without actionable genomic alterations, like EGFR or ALK, most patients eventually experience disease progression.3-5 TROP2 is a protein broadly expressed in a large majority of NSCLC tumours.6 There are currently no TROP2-directed ADCs approved for the treatment of patients with lung cancer.7,8

In previously untreated patients, datopotamab deruxtecan plus durvalumab (doublet; n=14) demonstrated an objective response rate (ORR) of 50.0%, including 7 partial responses (PR), and a disease control rate (DCR) of 92.9%. Response rates were higher in patients receiving datopotamab deruxtecan plus durvalumab and carboplatin (triplet; n=13) which demonstrated an ORR of 76.9%, including 10 PRs, and a DCR of 92.3%. Responses were observed across PD-L1 expression levels.

Saiama Waqar, MD, Siteman Cancer Center, Washington University School of Medicine, St. Louis, Missouri, and investigator in the trial, said: “Most patients with advanced non-small cell lung cancer experience disease progression after initial treatment, underscoring the need for more effective first-line treatment options. The TROPION-Lung04 results offer preliminary evidence for the efficacy of datopotamab deruxtecan in combination with durvalumab and chemotherapy in first-line advanced non-small cell lung cancer with no new safety signals. We eagerly await enrolment and results from the Phase III programme evaluating various datopotamab deruxtecan and immune checkpoint inhibitor combinations in this setting.”

Cristian Massacesi, Chief Medical Officer and Oncology Chief Development Officer, AstraZeneca, said: “Following the positive high-level results of TROPION-Lung01, these initial TROPION-Lung04 results in the first-line setting reinforce our confidence in datopotamab deruxtecan as a potential treatment option for patients with advanced non-small cell lung cancer. Through our robust clinical programme we are eager to continue evaluating this TROP2-directed antibody drug conjugate in lung cancer across treatment settings, alone and in novel combinations.”

Mark Rutstein, MD, Global Head, Oncology Clinical Development, Daiichi Sankyo, said: “These early trial results further demonstrate the potential for datopotamab deruxtecan to enhance response to immune checkpoint inhibitors in patients with advanced non-small cell lung cancer and without actionable genomic alterations. We look forward to continuing to evaluate this promising TROP2-directed antibody drug conjugate in multiple ongoing Phase III trials to address what has long been an unmet need for the lung cancer community across treatment settings.”

In both previously treated and untreated patients, the safety profiles of datopotamab deruxtecan and Imfinzi with and without carboplatin were consistent with other clinical trials and with the known safety profile of each agent. Grade 3 or greater treatment-emergent adverse events (TEAEs) occurred in 42.1% of patients receiving doublet therapy and 71.4% of patients receiving triplet therapy. In patients receiving triplet therapy, the most common Grade 3 or greater TEAEs (occurring in more than 15% of patients) were anaemia (36%) and thrombocytopenia (21%). No Grade 3 or greater TEAE occurred in more than 15% of patients receiving doublet therapy. Across treatment cohorts, there were four interstitial lung disease (ILD) events adjudicated as drug-related by an independent committee including one Grade 1 event, two Grade 2 events and one Grade 4 event. No Grade 5 ILD events were observed.

In the doublet cohort, 73.7% (n=14 of 19) of patients were previously untreated. In the triplet cohort, 92.9% (n=13 of 14) of patients were previously untreated. Both the doublet and triplet cohorts included patients with PD-L1 expression levels ranging from less than 1% (n=6, 6), 1-49% (n=6, 3) and 50% or greater (n=7, 5). As of the 6 March 2023 data cut-off, median study duration was six months for both cohorts and treatment was ongoing in 31.6% and 50.0% of patients in the doublet and triplet cohorts, respectively.

AstraZeneca and Daiichi Sankyo have three Phase III trials evaluating datopotamab deruxtecan-based combinations as potential 1st-line treatment options for patients with advanced or metastatic NSCLC without actionable genomic alterations compared to the respective standard of care for the patient population of each study.

  • AVANZAR is evaluating datopotamab deruxtecan plus Imfinzi and carboplatin in patients regardless of PD-L1 expression or tumour histology.
  • TROPION-Lung07 is evaluating datopotamab deruxtecan plus pembrolizumab with or without chemotherapy in patients with non-squamous disease and PD-L1 expression less than 50%.
  • TROPION-Lung08 is evaluating datopotamab deruxtecan plus pembrolizumab in patients with PD-L1 expression of 50% or greater.


Non-small cell lung cancer
More than one million people worldwide are diagnosed with advanced NSCLC each year.1,2 While targeted therapies and immune checkpoint inhibitors have improved patient outcomes, advanced NSCLC has a poor prognosis and is associated with worsening outcomes after each line of subsequent therapy.3-5

Most patients with NSCLC have tumours that do not express a known actionable genomic alteration (e.g., EGFR, ALK, ROS1, NTRK, BRAF, RET or MET).9-11 The current 1st-line standard of care for these patients is immune checkpoint inhibitors with or without platinum-based chemotherapy. Approximately 40-60% of tumours will not respond to this initial treatment and while these therapies may improve survival for patients whose tumours do respond, most will experience disease progression.5,7

TROP2, a transmembrane glycoprotein, is broadly expressed in a large majority of NSCLC tumours.6 There are currently no TROP2-directed ADCs approved for the treatment of lung cancer.

TROPION-Lung04 is an ongoing global, open-label, 11-cohort Phase Ib trial evaluating the efficacy and safety of datopotamab deruxtecan (4 mg/kg or 6 mg/kg) in combination with immunotherapy (Imfinzi, AZD2936 or MEDI5752) with or without up to four cycles of carboplatin in patients with advanced or metastatic NSCLC without actionable genomic alterations. Patients enrolled in the cohorts evaluating Imfinzi were previously untreated or had received one or fewer lines of systemic chemotherapy without concomitant immunotherapy. The primary endpoints of TROPION-Lung04 are safety and tolerability. Secondary endpoints include ORR, DCR, duration of response and progression-free survival as assessed by investigator. TROPION-Lung04 will enrol approximately 230 patients globally.

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, DXd) 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-negative breast cancer. Beyond the TROPION programme, datopotamab deruxtecan is also being evaluated in novel combinations in several ongoing trials. AstraZeneca is also researching a potential diagnostic test to help identify patients most likely to benefit from treatment with datopotamab deruxtecan.

Imfinzi (durvalumab) is a human monoclonal antibody that binds to the PD-L1 protein and blocks the interaction of PD-L1 with the PD-1 and CD80 proteins, countering the tumour’s immune-evading tactics and releasing the inhibition of immune responses.

Imfinzi is the only approved immunotherapy and the global standard of care in the curative-intent setting of unresectable, Stage III NSCLC in patients whose disease has not progressed after chemoradiation therapy based on the PACIFIC Phase III trial.

Imfinzi is also approved in the US, EU, Japan, China and many other countries around the world for the treatment of extensive-stage SCLC based on the CASPIAN Phase III trial. In an exploratory analysis in 2021, updated results from the CASPIAN trial showed Imfinzi plus chemotherapy tripled patient survival at three years versus chemotherapy alone. Additionally, Imfinzi is approved in combination with a short course of Imjudo (tremelimumab) and chemotherapy for the treatment of metastatic NSCLC in the US, EU and Japan based on the POSEIDON Phase III trial.

In addition to its indications in lung cancer, Imfinzi is also approved in combination with chemotherapy in locally advanced or metastatic biliary tract cancer in the US, EU, Japan and several other countries; in combination with Imjudo in unresectable hepatocellular carcinoma in the US, EU and Japan; and in previously treated patients with advanced bladder cancer in a small number of countries.

Since the first approval in May 2017, more than 200,000 patients have been treated with Imfinzi.

AstraZeneca has several ongoing registrational trials focused on testing Imfinzi in earlier stages of lung cancer, including in resectable NSCLC (ADJUVANT BR.31) and unresectable NSCLC (PACIFIC-2, 4, 5, 8 and 9), and in limited-stage SCLC (ADRIATIC).

As part of a broad development programme, Imfinzi is being tested as a single treatment and in combinations with other anti-cancer treatments for patients with SCLC, NSCLC, bladder cancer, several gastrointestinal (GI) cancers, ovarian cancer, endometrial cancer and other solid tumours.

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.
