Datroway (datopotamab deruxtecan or Dato-DXd) has been approved in the US for the treatment of adult patients with locally advanced or metastatic EGFR-mutated non-small cell lung cancer (NSCLC) who have received prior EGFR-directed therapy and platinum-based chemotherapy.Learn more about our TROP2 catalog.
This indication is approved under accelerated approval based on objective response rate (ORR) and duration of response (DoR). Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial.
The approval follows Priority Review and Breakthrough Therapy Designation by the Food and Drug Administration (FDA) based on results from a subgroup analysis of the TROPION-Lung05 Phase II trial and supported by data from the TROPION-Lung01 Phase III trial.
Jacob Sands, MD, Medical Oncology, Dana-Farber Cancer Institute and investigator in both trials, said: “Addressing disease progression in patients with advanced EGFR-mutated lung cancer after prior targeted therapy and chemotherapy is very challenging with limited later-line treatment options available. The US approval of datopotamab deruxtecan introduces a novel and needed treatment option to patients with advanced disease.”
Dave Fredrickson, Executive Vice President, Oncology Haematology Business Unit, AstraZeneca, said: “This first approval of Datroway in lung cancer provides a much-needed option to patients with advanced EGFR-mutated lung cancer whose disease has become resistant to past treatments, regardless of the driving mutation. We have long supported patients with EGFR-mutated lung cancer and are proud to bring another innovative treatment option to this community.”
Ken Keller, Global Head of Oncology Business, and President and CEO, Daiichi Sankyo, Inc, said: “With today’s accelerated approval, Datroway is now the first TROP2-directed medicine available for certain patients in the US living with lung cancer. We remain committed to our extensive clinical development programme to further identify where Datroway may be used in other types of lung and breast cancer.”
Andrea E. Ferris, President and CEO, LUNGevity, said: “For people with advanced EGFR-mutated non-small cell lung cancer whose disease progresses on initial treatments, additional options are limited. Today’s approval of Datroway offers a new treatment option for patients whose disease has progressed following treatment with an EGFR-directed therapy and chemotherapy.”
In TROPION-Lung05 and TROPION-Lung01, Datroway demonstrated a confirmed ORR of 45% (95% confidence interval [CI]: 35-54) in patients with previously treated locally advanced or metastatic EGFR-mutated NSCLC (n=114) as assessed by blinded independent central review (BICR). Complete responses were seen in 4.4% of patients and partial responses were seen in 40% of patients. The median DoR was 6.5 months (95% CI: 4.2-8.4).
The safety profile of Datroway was evaluated in a pooled analysis of 125 patients in the TROPION-Lung05, TROPION-Lung01 and TROPION-PanTumor01 trials. The safety profile observed across these trials was consistent with the known profile of this medicine with no new safety concerns identified.
Datroway is a specifically engineered TROP2-directed DXd antibody drug conjugate (ADC) discovered by Daiichi Sankyo and being jointly developed and commercialised by AstraZeneca and Daiichi Sankyo.
AstraZeneca and Daiichi Sankyo are evaluating Datroway alone and with Tagrisso (osimertinib) in other advanced or metastatic EGFR-mutated NSCLC settings in the TROPION-Lung14 and TROPION-Lung15 Phase III trials.
