Primary Outcome Measures
NameTimeMethod
Progression-Free Survival (PFS) in TROP2 biomarker positive participants.Approximately 4 years

PFS is defined as time from randomisation until progression per RECIST 1.1 as assessed by BICR, or death due to any cause.

The analysis will include all randomised participants, as randomised, regardless of whether the participant withdraws from randomised therapy, receives another anti-cancer therapy or clinically progresses prior to RECIST 1.1 progression, in the following population:

• TROP2 biomarker positive population

The measure of interest is the HR of PFS. PFS by investigator will be reported as a sensitivity analysis.

Overall Survival (OS) in TROP2 biomarker positive participants.Approximately 6 years

OS is defined as the time from randomisation until the date of death due to any cause.

The analysis will include all randomised participants, as randomised, regardless of whether the participant withdraws from randomised therapy or receives another anti-cancer therapy, in the following population:

• TROP2 biomarker positive population The measure of interest is the HR of OS.

Secondary Outcome Measures
NameTimeMethod
Progression-Free Survival (PFS) in the FAS population.Approximately 4 years

PFS is defined as time from randomisation until progression per RECIST 1.1 as assessed by BICR, or death due to any cause.

The analysis will include all randomised participants, as randomised, regardless of whether the participant withdraws from randomised therapy, receives another anti cancer therapy or clinically progresses prior to RECIST 1.1 progression, in the following population:

• FAS population

The measure of interest is the HR of PFS. PFS by investigator will be reported as a sensitivity analysis.

Overall Survival (OS) in the FAS population.Approximately 6 years

OS is defined as the time from randomisation until the date of death due to any cause.

The analysis will include all randomised participants, as randomised, regardless of whether the participant withdraws from randomised therapy or receives another anti-cancer therapy, in the following population:

• FAS population The measure of interest is the HR of OS.

Assessment of Objective Response Rate (ORR) by BICR in TROP2 biomarker positive and FAS populationsApproximately 4 years

ORR is defined as the proportion of participants who have a CR or PR, as determined by BICR per RECIST 1.1.

The analyses will include all randomised participants, as randomised, with measurable disease at baseline, in the following populations:

* TROP2 biomarker positive population

* FAS population Data obtained from randomisation up until progression, or the last evaluable assessment in the absence of progression, will be included in the assessment of ORR, regardless of whether the participant withdraws from therapy. Participants who go off treatment without a response or progression, receive a subsequent therapy, and then respond will not be included as responders in the ORR.

The measure of interest is the OR of the ORR. ORR by investigator will be reported as a sensitivity analysis.

Assessment of Duration of Response (DoR) by BICR in TROP2 biomarker positive and FAS populationsApproximately 4 years

DoR is defined as the time from the date of first documented response until date of documented progression per RECIST 1.1, as assessed by BICR and investigator assessment or death due to any cause.

The analyses will include all randomised participants who have a response, as randomised, regardless of whether the participant withdraws from randomised therapy, receives another anti cancer therapy or clinically progresses prior to RECIST 1.1 progression, in the following populations:

* TROP2 biomarker positive population

* FAS population The measure of interest is the median of DoR. DoR by investigator will be reported as a sensitivity analysis.

Participant-reported lung cancer symptoms of NSCLC and participant-reported GHS/QOL in participants treated with Dato-DXd in combination with rilvegostomig relative to pembrolizumab.Approximately 6 years

Time to deterioration in: pulmonary symptoms (dyspnoea, cough, and chest pain) as measured by the NSCLC-SAQ, in overall lung cancer symptoms as measured by the NSCLC-SAQ, and in GHS/QoL as measured by the GHS/QoL scale from EORTC IL172.

Time to deterioration is defined as the time from randomisation until the date of deterioration. Deterioration is defined as change from baseline that reaches a clinically meaningful deterioration threshold. The analyses will include all randomised participants, in the following populations:

* TROP2 biomarker positive population

* FAS population The measure of interest is the HR of time to deterioration in pulmonary symptoms, HR of time to deterioration in overall lung cancer symptoms, and HR of time to deterioration in GHS/QoL.

Participant-reported physical functioning in participants treated with Dato DXd in combination with rilvegostomig relative to pembrolizumab.Approximately 6 years

Time to deterioration in physical functioning as measured by PROMIS Physical Function short form 8c.

Time to deterioration is defined as the time from randomisation until the date of deterioration. Deterioration is defined as change from baseline that reaches a clinically meaningful deterioration threshold. The analyses will include all randomised participants, in the following populations:

* TROP2 biomarker positive population

* FAS population The measure of interest is the HR of time to deterioration in physical functioning.

Pharmacokinetics (PK)Approximately 6 years

Concentration of rilvegostomig, Dato-DXd, total anti TROP2 antibody, and MAAA 1181a (payload deruxtecan) in plasma or serum and PK parameters (peak and trough concentrations).

ImmunogenicityApproximately 6 years

Presence of ADA for Dato-DXd and rilvegostomig (confirmatory results, titres and neutralising antibodies for confirmed positive samples).

Second Progression-Free Survival (PFS2).Approximately 6 years

PFS2 is defined as the time from randomisation to the earliest of the progression events (following the initial progression), subsequent to first subsequent therapy, or death. Progression event includes radiological (RECIST 1.1) or clinical disease progression.

The date of second progression will be recorded by the investigator in the eCRF and defined according to local standard practice.

The analyses will include all randomised participants, as randomised, regardless of whether the participant withdraws from subsequent therapy and regardless of missed visits, in the following populations:

* TROP2 biomarker positive population

* FAS population The measure of interest is the HR of PFS2.
