Study Endpoints

Primary Endpoints

Dose Limiting Toxicity (DLT) - Phase Ia
Baseline to Day 21 of the first treatment cycle
Serious Adverse Events (SAEs)
Baseline to 30 days after the last dose of study treatment

Adverse events that are fatal, life-threatening, or result in hospitalization or prolonged hospitalization, persistent or significant disability/incapacity/substantial disruption of the ability to lead a normal life, congenital anomaly/birth defect or major medical events or reactions

Treatment-Emergent Adverse Event (TEAE)
Baseline to 30 days after the last dose of study treatment

AEs that occur or worsen on or after the first dose of study treatment

Treatment-Related Adverse Event
Baseline to 30 days after the last dose of study treatment

Any reaction, side effect, or untoward event that occurs during the course of the clinical trial is considered related to the study drug.

Objective Response Rate (ORR) as assessed by investigator - Phase Ib

Frequently asked questions about MRG007

What is MRG007 used for?

MRG007 is an investigational small molecule being developed for the treatment of locally advanced or metastatic solid tumors, including colorectal cancer, gastric cancer, and pancreatic cancer. It is currently in Phase 1 clinical development and is not yet approved by the FDA.

What does MRG007 target?

MRG007 targets CDH17, a protein involved in cell adhesion. By binding to CDH17, the drug aims to interfere with tumor growth and progression in solid tumors. This mechanism is being evaluated in early-stage clinical trials for patients with advanced cancers.

Who makes MRG007?

MRG007 is being developed by ArriVent BioPharma, Inc., a biopharmaceutical company traded on the NASDAQ under the ticker symbol AVBP. The company is conducting clinical trials to evaluate the safety and efficacy of this investigational drug in patients with advanced solid tumors.

What phase is MRG007 in?

MRG007 is currently in Phase 1 clinical development. It is an investigational drug, meaning it has not been approved by regulatory authorities. The ongoing Phase 1 trial is recruiting patients to assess the drug's safety, tolerability, and preliminary efficacy in advanced solid tumors.

What clinical trials is MRG007 in?

MRG007 is being studied in a Phase 1 clinical trial with the identifier NCT07066657, titled 'A Study of MRG007 (ARR-217) in Patients With Advanced Solid Tumors.' This recruiting trial plans to enroll approximately 572 participants across the United States and China, including patients with colorectal, gastric, and pancreatic cancers.

Is MRG007 the same as ARR-217?

Yes, MRG007 is also known as ARR-217. The clinical trial NCT07066657 refers to the drug as MRG007 (ARR-217), indicating that both names are used interchangeably for the same investigational compound being developed by ArriVent BioPharma.
