Brief summary

This is a Phase III, randomised, open-label, multicentre, global study assessing the efficacy and safety of adjuvant Dato-DXd in combination with rilvegostomig compared with SoC, after complete surgical resection (R0) in participants with Stage I adenocarcinoma NSCLC who are ctDNA-positive, as determined by the Sponsor-designated ctDNA assay, or have at least one high-risk pathological feature.

Detailed description

The primary objective of the study is to assess the efficacy and safety of adjuvant Dato-DXd in combination with rilvegostomig relative to SoC, after complete surgical resection (R0) in participants with Stage I adenocarcinoma NSCLC who are ctDNA-positive, as determined by the Sponsor-designated ctDNA assay, or have at least one high-risk pathological feature.

Design outcomes

Primary

MeasureTime frameDescription
Disease-Free Survival (DFS) using BICR in participants with Stage I adenocarcinoma NSCLC who are ctDNA-positive or having at least one high-risk pathological feature treated with adjuvant Dato-DXd in combination with rilvegostomig relative to SoCFrom date of randomisation up to approximately 10 years.The analysis will include all randomised participants as randomised. All events will be included, regardless of whether the participant withdraws from randomised therapy or receives another anti-cancer therapy. The measure of interest is the HR of DFS. Descriptive analyses of Dato-DXd in combination with rilvegostomig versus rilvegostomig monotherapy and rilvegostomig monotherapy versus SoC will be performed to assess contribution of components.

Secondary

MeasureTime frameDescription
Overall Survival (OS) in participants with Stage I adenocarcinoma NSCLC who are ctDNA-positive or having at least one high-risk pathological feature treated with adjuvant Dato-DXd in combination with rilvegostomig relative to SoCFrom date of randomisation up to approximately 10 years.The analysis will include all randomised participants as randomised. All deaths will be included, regardless of whether the participant withdraws from therapy or receives another anti-cancer therapy. The measure of interest is the HR of OS. Descriptive analyses of Dato-DXd in combination with rilvegostomig versus rilvegostomig monotherapy and rilvegostomig monotherapy versus SoC will be performed to assess contribution of components.
Participant-reported physical function in participants with Stage I adenocarcinoma NSCLC who are ctDNA-positive or having at least one high-risk pathological feature treated with adjuvant Dato-DXd in combination with rilvegostomig relative to SoCMeasured at weeks 12, 24 and 48.The analysis will include all randomised participants as randomised. The physical function will be measured by the PROMIS SF PF 8c. Data from PROMIS SF PF 8c will capture participants' perceived ability to perform specific activities from daily life and will be scored on a 5-point rating scale. The measure of interest will be the between treatment group difference in adjusted mean in physical function scores. Descriptive analyses of Dato-DXd in combination with rilvegostomig versus rilvegostomig monotherapy and rilvegostomig monotherapy versus SoC will be performed to assess contribution of components.
Participant-reported GHS/QoL in participants with Stage I adenocarcinoma NSCLC who are ctDNA-positive or having at least one high-risk pathological feature treated with adjuvant Dato-DXd in combination with rilvegostomig relative to SoCMeasured at weeks 12, 24 and 48.The analysis will include all randomised participants as randomised. The GHS/QoL scores will be measured by the GHS/QoL scale from EORTC IL172. The measure of interest will be the between treatment group difference in adjusted mean in GHS/QoL scores. Descriptive analyses of Dato-DXd in combination with rilvegostomig versus rilvegostomig monotherapy and rilvegostomig monotherapy versus SoC will be performed to assess contribution of components.
Pharmacokinetics (PK)Up to 30 or 90 days post-last dose of study intervention.Concentration of Dato-DXd, total anti-TROP2 antibody, and MAAA-1181a (payload deruxtecan) in plasma or serum.
ImmunogenicityUp to 30 or 90 days post-last dose of study intervention.Presence of ADAs for Dato-DXd and rilvegostomig (confirmatory results: titres and neutralising antibodies for confirmed positive samples).
