Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Objective Response Rate (ORR) Based on Blinded Independent Central Review (BICR) Per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) | From first dose of trial drug up to a minimum of last dose + 65 days or data cutoff date; median (min, max) time on trial was 3.4 (2.2, 6.5) months at data cut off | ORR based on BICR was defined as the percentage of participants with best overall response (BOR) of complete response (CR) plus partial response (PR). CR: Disappearance of all target non-nodal lesions. Any target lymph node must have had a reduction in short axis to \<10 mm, NOT total disappearance. PR: At least a 30% decrease in the sum of the diameters of target lesions, taken as reference the baseline sum of diameters. The percentage of participants who experience a CR or PR as assessed by BICR based on RECIST 1.1 is presented. |
| Secondary | Duration of Response (DOR) Based on BICR Per RECIST 1.1 | Approximately 24 months | DOR was defined as time from the first documentation of OR until the first documentation of disease progression (PD) or death due to any cause, whichever occured first. Only participants who had achieved OR were evaluated for DOR. CR: Disappearance of all target non-nodal lesions. Any target lymph node must have reduction in short axis to \<10 mm, NOT total disappearance. PD: At least 20% increase in the sum of the diameters of target lesions, taken as reference smallest sum on trial (this included the baseline sum if that is the smallest on trial). In addition to the relative increase of 20%, the sum must have also demonstrated an absolute increase of at least 5 mm. If a participant was missing lesion data at a disease assessment and yet progressive disease criteria was met despite the missing data, the participant would be classified as having PD. |
| Secondary | Disease Control (DC) Based on BICR Per RECIST 1.1 | Approximately 24 months | DC was defined as CR + PR + stable disease (SD). CR: Disappearance of all target non-nodal lesions. Any target lymph node must have had a reduction in short axis to \<10 mm, NOT total disappearance. PR: At least a 30% decrease in the sum of the diameters of target lesions, taken as reference the baseline sum of diameters. SD: Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD. PD: At least 20% increase in the sum of the diameters of target lesions, taken as reference smallest sum on trial (this included the baseline sum if that is the smallest on trial). In addition to the relative increase of 20%, the sum must have also demonstrate an absolute increase of at least 5 mm. If a participant was missing lesion data at a disease assessment and yet progressive disease criteria was met despite the missing data, the participant would be classified as having PD. |
| Secondary | Duration of DC Based on BICR Per RECIST 1.1 | Approximately 24 months | Duration of DC was defined as time from first documentation of CR,PR, or SD until first documentation of disease progression or death due to any cause, whichever occurred first. Only participants who had achieved CR,PR, or SD would be evaluated for Duration of DC. CR:Disappearance of all target non-nodal lesions.Any target lymph node must have reduction in short axis to \<10 mm,NOT total disappearance.PR:At least a 30% decrease in sum of diameters of target lesions, taken as reference baseline sum of diameters. SD:Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD. PD:At least 20% increase in sum of diameters of target lesions, taken as reference smallest sum on trial.In addition to relative increase of 20%, sum must have also demonstrated an absolute increase of at least 5 mm.If participant was missing lesion data at disease assessment and yet progressive disease criteria was met despite missing data, participant would be classified as having PD. |
| Secondary | Progression-free Survival (PFS) Based on BICR Per RECIST 1.1 | Approximately 24 months | PFS was defined as the time from first dose of tarlatamab until PD or death from any cause, whichever occurred first. At least a 20% increase in the sum of the diameters of target lesions, taken as reference the smallest sum on trial (this included the baseline sum if that was the smallest on trial). In addition to the relative increase of 20%, the sum must have also demonstrated an absolute increase of at least 5 mm. If a participant was missing lesion data at a disease assessment and yet progressive disease criteria was met despite the missing data, the participant would be classified as having PD. |
| Secondary | ORR Based on Investigator Assessment Per RECIST 1.1 | Approximately 24 months | ORR based on investigator assessment was defined as the percentage of participants with BOR of CR plus PR. CR: Disappearance of all target non-nodal lesions. Any target lymph node must have had a reduction in short axis to \<10 mm, NOT total disappearance. PR: At least a 30% decrease in the sum of the diameters of target lesions, taken as reference the baseline sum of diameters. |
| Secondary | DOR Based on Investigator Assessment Per RECIST 1.1 | Approximately 24 months | DOR was defined as time from the first documentation of OR until the first documentation of PD or death due to any cause, whichever occurred first. Only participants who had achieved OR would be evaluated for DOR. PD: At least 20% increase in the sum of the diameters of target lesions, taken as reference smallest sum on trial (this included the baseline sum if that was the smallest on trial). In addition to the relative increase of 20%, the sum must have also demonstrated an absolute increase of at least 5 mm. If a participant was missing lesion data at a disease assessment and yet progressive disease criteria was met despite the missing data, the participant would be classified as having PD. |
| Secondary | DC Based on Investigator Assessment Per RECIST 1.1 | Approximately 24 months | DC was defined as CR + PR + SD. CR: Disappearance of all target non-nodal lesions. Any target lymph node must have had a reduction in short axis to \<10 mm, NOT total disappearance. PR: At least a 30% decrease in the sum of the diameters of target lesions, taken as reference the baseline sum of diameters. SD: Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD. PD: At least 20% increase in the sum of the diameters of target lesions, taken as reference smallest sum on trial (this included the baseline sum if that was the smallest on trial). In addition to the relative increase of 20%, the sum must have also demonstrated an absolute increase of at least 5 mm.

In addition to the relative increase of 20%, the sum must have also demonstrated an absolute increase of at least 5 mm.
