Un estudio clínico de MK-2870 solo o con quimioterapia para tratar cánceres gastrointestinales (MK-9999-02A)

28 de octubre de 2026 actualizado por: Merck Sharp & Dohme LLC

Un estudio de fase 1/2 para evaluar la seguridad y eficacia de MK-2870 en monoterapia o en combinación con otros agentes anticancerígenos en cánceres gastrointestinales

Researchers want to learn if sacituzumab tirumotecan (MK-2870) alone or with other treatments can treat certain gastrointestinal (GI) cancers. The GI cancers being studied are either advanced (the cancer has spread to other parts of the body), or unresectable (the cancer cannot be removed with surgery). The goals of this study are to learn:

  • About the safety of sacituzumab tirumotecan alone or with other treatments and if people tolerate it
  • How many people have the cancer respond (get smaller or go away) to treatment

Medidas de resultado primarias

Medida de resultado
Medida Descripción
Periodo de tiempo
Number of Participants Who Experience a Dose-limiting Toxicity (DLT)
Periodo de tiempo: Up to approximately 4 weeks

A DLT is a medical problem related to the study medicine that prevents giving participants a higher dose or may prevent giving the participant the same dose. The number of participants who experience a DLT will be reported.

Up to approximately 4 weeks
Number of Participants Who Experience One or More Adverse Events (AEs)
Periodo de tiempo: Up to approximately 63 months

An AE is a health problem that happens or worsens during the study. The number of participants who have an AE during the study will be reported.

Up to approximately 63 months
Number of Participants who Discontinue Study Treatment due to an AE
Periodo de tiempo: Up to approximately 63 months

An AE is a health problem that happens or worsens during a study. The number of participants who stop study treatment will be reported.

Up to approximately 63 months
Objective Response Rate (ORR) per Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 as Assessed by Blinded Independent Central Review (BICR)
Periodo de tiempo: Up to approximately 63 months

ORR is defined as the percentage of participants with 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. The percentage of participants who experience CR or PR as assessed by Blinded Independent Central Review (BICR) will be presented.

Up to approximately 63 months

Medidas de resultado secundarias

Medida Descripción
Periodo de tiempo
Duration of Response (DOR) per RECIST 1.1 as Assessed by BICR
Periodo de tiempo: Up to approximately 63 months

For participants who demonstrate a confirmed Complete Response or Partial Response, DOR is defined as the time from first documented evidence of CR or PR until progressive disease (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 63 months
Progression-free Survival (PFS) per RECIST 1.1 as Assessed by BICR
Periodo de tiempo: Up to approximately 63 months

PFS is defined as the time from start of study treatment to the first documented progressive disease (PD) or death due to any cause, whichever occurs first. According to RECIST 1.1, PD is defined as ≥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 ≥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 63 months
Overall Survival (OS)
Periodo de tiempo: Up to approximately 63 months

OS is the length of time from when the participant starts treatment until death from any cause
