Teilstudie 06C: Eine Studie zu Sacituzumab Tirumotecan (MK-2870) mit Pembrolizumab (MK-3475) und Chemotherapie bei Teilnehmern mit lokal fortgeschrittenem inoperablem/metastasiertem gastroösophagealem Adenokarzinom der ersten Wahl (MK-3475-06C/KEYMAKER-U06)

12. November 2026 aktualisiert von: Merck Sharp & Dohme LLC

Eine offene Phase-1/2-Umbrella-Plattform-Designstudie von MK-2870 mit Pembrolizumab (MK-3475) und Chemotherapie bei Teilnehmern mit 1 l lokal fortgeschrittenem inoperablem/metastasiertem gastroösophagealen Adenokarzinom (Magenadenokarzinom, Adenokarzinom des gastroösophagealen Übergangs und Adenokarzinom des Ösophagus): Teilstudie 06C

This is a phase 1/2, multicenter, open-label umbrella platform study that will evaluate the safety and tolerability of investigational agents with pembrolizumab and fluoropyrimidine chemotherapy for the first-line (1L) treatment of participants with locally advanced unresectable or metastatic human epidermal growth factor receptor 2 (HER2)-negative gastric, gastroesophageal junction, or esophageal adenocarcinoma.

This substudy will have two phases: a safety lead-in phase and an efficacy phase. The safety lead-in phase will be used to evaluate the safety and tolerability, and to establish a recommended Phase 2 dose (RP2D) for investigational agents in combination with chemotherapy and immunotherapy. There is no formal hypothesis in this study.

Was misst die Studie?

Primäre Ergebnismessungen

Ergebnis Maßnahme
Maßnahmenbeschreibung
Zeitfenster
Safety Lead-in Phase: Number of Participants Who Experience One or More Dose-Limiting Toxicities (DLTs)
Zeitfenster: Up to approximately 28 days

DLTs are defined as any treatment-emergent adverse events (TEAEs) not attributable to disease or disease-related processes that occur during the DLT evaluation period and are a Grade 3 or higher according to the National Cancer Institute Common Terminology for Adverse Events (NCI CTCAE) Version 5.0. The percentage of participants who experience at least one DLT will be reported.
Up to approximately 28 days
Safety Lead-in Phase: Number of Participants Who Experienced an Adverse Event (AE)
Zeitfenster: Up to approximately 28 days

An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study intervention.
Up to approximately 28 days
Safety Lead-in Phase: Number of Participants Who Discontinued Study Intervention Due to an AE
Zeitfenster: Up to approximately 28 days

An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study intervention.
Up to approximately 28 days
Objective Response Rate (ORR) Per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) as Assessed by Blinded Independent Central Review (BICR)
Zeitfenster: Up to approximately 28 months

ORR is defined as the percentage of participants in the analysis population who have a Complete Response (CR: Disappearance of all target lesions) or a Partial Response (PR: At least a 30% decrease in the sum of diameters of target lesions) per RECIST 1.1. The percentage of participants who experience CR or PR as assessed by BICR will be presented.
Up to approximately 28 months

Ergebnis Maßnahme
Maßnahmenbeschreibung
Zeitfenster
Progression-Free Survival (PFS) per RECIST 1.1 as Assessed by BICR
Zeitfenster: Up to approximately 55 months

PFS is defined as the time from randomization to the first documented progressive disease (PD) or death from any cause, whichever occurs first. Per RECIST 1.1, PD is defined as at least a 20% increase in the sum of diameters of target lesions. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. The appearance of one or more new lesions is also considered PD. PFS as assessed by BICR will be presented.
Up to approximately 55 months
Duration of Response (DOR) Per RECIST 1.1 as Assessed by BICR
Zeitfenster: Up to approximately 55 months

For participants who demonstrate a confirmed Complete Response (CR: disappearance of all target lesions) or Partial Response (PR: at least a 30% decrease in the sum of diameters of target lesions) per RECIST 1.1, DOR is defined as the time from first documented evidence of CR or PR until PD or death. Per RECIST 1.1, PD is defined as at least a 20% increase in the sum of diameters of target lesions. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. The appearance of one or more new lesions is also considered PD. DOR as assessed by BICR will be presented.
Up to approximately 55 months
Overall Survival (OS)
Zeitfenster: Up to approximately 55 months

OS is defined as the time from randomization to the date of death from any cause.
Up to approximately 55 months
Number of Participants Who Experience an Adverse Event (AE)
Zeitfenster: Up to approximately 55 months

An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study intervention.
Up to approximately 55 months
Number of Participants Who Discontinue Study Treatment Due to an AE
Zeitfenster: Up to approximately 55 months

An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study intervention.
Up to approximately 55 months
Incidence of Antidrug Antibodies (ADA) to investigational agents - (sacituzumab tirumotecan (sac-TMT, MK-2870) and patritumab deruxtecan (HER3-DXd))
Zeitfenster: At designated timepoints up to approximately 55 months

Blood samples collected at designated timepoints will be used to determine the ADA response to investigational agents. The incidence of ADAs over time will be presented.
At designated timepoints up to approximately 55 months
