Phase 1: Number of Participants With Dose-limiting Toxicities (DLTs)
DLTs are defined as the events pre-specified in the protocol and which are not clearly due to the underlying disease or extraneous causes. Toxicities will be graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) version 5.0.
Time frame: During Cycle 1 (cycle length = 21 days)
Phase 1: Number of Participants With Treatment-emergent Adverse Events (TEAEs)
An adverse event (AE) is any untoward medical occurrence in a participant administered a pharmaceutical product and that does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. TEAEs are defined as those AEs with start or worsening date during the on-treatment period (from the start date of trial intervention to 35 days \[28 (+7) days\] after the last dose date of trial intervention).
Time frame: Up to approximately 2.9 years
Phase 2: Objective Response Rate (ORR) as Assessed by Investigator
Objective response rate (ORR) is defined as the percentage of participants with a best overall response (BOR) of confirmed complete response (CR) or confirmed partial response (PR), as assessed by the investigator per RECIST v1.1.
Time frame: Up to approximately 2.9 years
Phase 1: ORR as Assessed by Investigator
ORR is defined as the percentage of participants with a BOR of confirmed CR or confirmed PR, as assessed by the investigator per RECIST v1.1.
Time frame: Up to approximately 2.9 years
Phase 2: Number of Participants With TEAEs
An AE is any untoward medical occurrence in a participant administered a pharmaceutical product and that does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. TEAEs are defined as those AEs with start or worsening date during the on-treatment period (from the start date of trial intervention to 35 days \[28 (+7) days\] after the last dose date of trial intervention).
Time frame: Up to approximately 2.9 years
Phase 1 and 2: Duration of Response (DoR) as Assessed by the Investigator
DoR is defined as the time (in months) from the date of initial response (CR or PR) to the earlier date of the first objective documentation of radiographic disease progression or death due to any cause.
Time frame: Up to approximately 2.9 years
Phase 1 and 2: Clinical Benefit Rate (CBR) as Assessed by the Investigator
CBR is defined as the percentage of participants with a BOR of confirmed CR, confirmed PR, or stable disease (SD) lasting ≥183 days, as assessed by the investigator per RECIST v1.1.
Time frame: Up to approximately 2.9 years
Phase 1 and 2: Disease Control Rate (DCR) as Assessed by the Investigator
DCR is defined as the percentage of participants with a BOR of confirmed CR, confirmed PR, or SD as assessed by the investigator per RECIST v1.1.
Time frame: Up to approximately 2.9 years
Phase 1 and 2: Time to Response (TTR) as Assessed by the Investigator
TTR is defined as the time (in months) from the start date of trial intervention (randomization for randomized cohort) to the date of the first documentation of objective response in responders (BOR of confirmed CR or confirmed PR as assessed by the investigator per RECIST v1.1).
Time frame: Up to approximately 2.9 years
Phase 1 and 2: Best Percentage Change in the SoD of Measurable Tumors as Assessed by Investigator
The best percentage change in SoD as assessed by the investigator per RECIST v1.1, defined as the percentage change in the smallest SoD from all postbaseline tumor assessments, taking as reference the baseline SoD.
Time frame: Up to approximately 2.9 years
Phase 1 and 2: Progression-free Survival (PFS) as Assessed by the Investigator
PFS is defined as the time (in months) from the start date of trial intervention (randomization for randomized cohort) to the earlier date of the first objective documentation of radiographic disease progression as assessed by investigator per RECIST v1.1 or death due to any cause.
Time frame: Up to approximately 2.9 years
Phase 1 and 2: Overall Survival (OS)
OS is defined as the time (in months) from the start date of trial intervention (date of randomization for randomized cohort) to the date of death due to any cause.

Started Oct 2026 (actual). Primary completion is estimated for Sep 2029, 35 months after the start.
Of 254 industry-sponsored phase 1/2 interventional studies under Carcinoma, Non-Small-Cell Lung, half reached primary completion within 64 months of starting (the median), counting those still running; a quarter within 41 and three quarters within 84. This study's planned 35 months is below that.
Counting every sponsor, half of 366 studies reached it within 66 months; a quarter within 42 and three quarters within 87.
