Study Endpoints

Primary Endpoints

Dose-Limiting Toxicity (DLT)
Cycle 1 (up to 21 days)

The occurrence of any of the following toxicities during Cycle 1 will be considered a DLT, if assessed by the investigator related to study intervention administration: * Grade 4 nonhematologic toxicity * Grade 4 hematologic toxicity lasting ≥7 days, except thrombocytopenia * Any nonhematologic AE ≥Grade 3 in severity, with exceptions * Any Grade 3 or Grade 4 nonhematologic laboratory value, as with pre-specified exceptions * Any Grade 3 or Grade 4 laboratory abnormalities, with the exceptions * Febrile neutropenia Grade 3 or Grade 4 * Prolonged delay (\>2 weeks) in initiating Cycle 2 due to intervention-related toxicity * Any study drug toxicity that causes the participant to discontinue study drug during Cycle 1 * Missing \>25% of MK-4700 doses as a result of drug-related AEs during the first cycle * Grade 5 toxicity

Percentage of Participants Who Experience an Adverse Event (AE)
Up to approximately 4.5 years

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.

Percentage of Participants who Discontinue Study Treatment Due to an AE
Up to approximately 4.5 years

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.

Frequently asked questions about MK-4700

What is MK-4700 used for?

MK-4700 is an investigational monoclonal antibody being studied for the treatment of malignant neoplasms, which are cancerous tumors. It is being developed by Merck & Company, Inc. for use in oncology, specifically in patients with advanced or metastatic solid tumors.

What does MK-4700 target?

The specific molecular target of MK-4700 is not disclosed in the available information. It is described as a monoclonal antibody, which typically works by binding to a specific protein involved in cancer growth, but the exact target has not been publicly specified.

Who makes MK-4700?

MK-4700 is being developed by Merck & Company, Inc., a pharmaceutical company traded on the New York Stock Exchange under the ticker symbol MRK. The company is conducting clinical research on this investigational drug for oncology indications.

What phase is MK-4700 in?

MK-4700 is in Phase 1 clinical development. It is an investigational drug, meaning it has not been approved by regulatory authorities and is still undergoing clinical trials to evaluate its safety and efficacy in patients with advanced or metastatic solid tumors.

What clinical trials is MK-4700 in?

MK-4700 has been studied in one clinical trial with the identifier NCT06894771, titled "A Study of MK-4700 Alone or With Pembrolizumab in Participants With Advanced or Metastatic Solid Tumors (MK-4700-001)." This Phase 1 trial has been completed and enrolled 5 participants.

Is MK-4700 the same as pembrolizumab?

No, MK-4700 is not the same as pembrolizumab. Pembrolizumab is a separate drug, also developed by Merck, that is being studied in combination with MK-4700 in clinical trial NCT06894771. MK-4700 is a distinct investigational monoclonal antibody being evaluated alone or with pembrolizumab.
