Uno studio clinico su MK-2870 da solo o con chemioterapia per il trattamento dei tumori gastrointestinali (MK-9999-02A)

28 ottobre 2026 aggiornato da: Merck Sharp & Dohme LLC

Uno studio di fase 1/2 per valutare la sicurezza e l'efficacia della monoterapia MK-2870 o in combinazione con altri agenti antitumorali nei tumori gastrointestinali

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

Cosa sta misurando lo studio?

Misure di risultato primarie

Misura del risultato
Misura Descrizione
Lasso di tempo
Number of Participants Who Experience a Dose-limiting Toxicity (DLT)
Lasso di tempo: 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)
Lasso di tempo: 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
Lasso di tempo: 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)
Lasso di tempo: 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

Misure di risultato secondarie

Misura del risultato
Misura Descrizione
Lasso di tempo
Duration of Response (DOR) per RECIST 1.1 as Assessed by BICR
Lasso di tempo: 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
Lasso di tempo: 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)
Lasso di tempo: Up to approximately 63 months

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

Up to approximately 63 months
