A Phase III, Randomised, Open-label, Global Study of Adjuvant Datopotamab Deruxtecan (Dato-DXd) in Combination With Rilvegostomig or Rilvegostomig Monotherapy Versus Standard of Care, Following Complete Tumour Resection, in Participants With Stage I Adenocarcinoma Non-small Cell Lung Cancer Who Are ctDNA-positive or Have High-risk Pathological Features (TROPION-Lung12)

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.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
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 SoC
Time Frame: From 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.
From date of randomisation up to approximately 10 years.

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
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 SoC
Time Frame: From 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.
From date of randomisation up to approximately 10 years.
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 SoC
Time Frame: Measured 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.
Measured at weeks 12, 24 and 48.
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 SoC
Time Frame: Measured 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.
Measured at weeks 12, 24 and 48.
Pharmacokinetics (PK)
Time Frame: 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.
Up to 30 or 90 days post-last dose of study intervention.
Pharmacokinetics (PK)
Time Frame: Up to 30 or 90 days post-last dose of study intervention.
Concentration of rilvegostomig in plasma or serum.
Up to 30 or 90 days post-last dose of study intervention.
Pharmacokinetics (PK)
Time Frame: Up to 30 or 90 days post-last dose of study intervention.
PK parameters (peak and through concentrations).
Up to 30 or 90 days post-last dose of study intervention.
Immunogenicity
Time Frame: Up to 30 or 90 days post-last dose of study intervention.
