AstraZeneca's Dato-DXd-Based Combo Therapies Show Promising Activity In Lung Cancer Patients

AstraZeneca Plc (NASDAQ:AZN) reported initial results from the TROPION-Lung02 phase 1b trial showing that datopotamab deruxtecan (Dato-DXd) in combination with pembrolizumab with or without platinum chemotherapy demonstrated promising clinical activity and a tolerable safety profile in non-small cell lung cancer (NSCLC) without actionable genomic alterations.
Datopotamab deruxtecan is jointly developed by Daiichi Sankyo (OTC:DSKNY) and AstraZeneca.
The interim analysis demonstrated an overall response rate in the overall population of 37% in patients receiving datopotamab deruxtecan plus Merck & Co Inc's Keytruda (pembrolizumab) (doublet therapy).
The data showed an ORR of 41% in patients receiving datopotamab deruxtecan plus pembrolizumab and platinum chemotherapy (triplet therapy).
A disease control rate (DCR) of 84% was seen with doublet and triplet combination therapy.
In previously untreated patients, ORRs of 62% (on doublet therapy) and 50% (on triplet therapy) were observed.
Eight partial responses (PRs) were seen in patients receiving doublet therapy, and 10 PRs (three pending confirmation) were seen in patients receiving triplet therapy.
A DCR of 100% was observed with doublet therapy and 90% with triplet therapy.
