A Study of MRG006A in the Treatment of Patients With Advanced Solid Tumors
- Registration Number
- NCT07093970
- Lead Sponsor
- Shanghai Miracogen Inc.
- Brief Summary
The objective of this study is to assess the safety, efficacy, pharmacokinetics, and immunogenicity of MRG006A in patients with advanced solid tumors.
- Detailed Description
This study consists of two parts. Phase I is a dose escalation study to determine the maximum tolerated dose (MTD) and recommended phase II dose (RP2D) of MRG006A. Phase II is a dose expansion study to further assess the efficacy, safety, pharmacokinetics and immunogenicityof MRG006A at confirmed RP2D.

Group Intervention Description MRG006A MRG006A All patients in Phase I and Phase II will be administrated MRG006A on Day 1 of every 3 weeks (21-day cycle).
- Primary Outcome Measures
Name Time Method Maximum Tolerated Dose (MTD) - Phase I Baseline to the end of the first treatment cycle (each cycle is 21 days). The highest dose confirmed wherein less than 2 out of 6, or \< 33% of evaluable patients in a treatment cohort experiences dose-limiting toxicity (DLT).
Recommended Phase II Dose (RP2D) - Phase I Baseline to study completion (up to 24 months). The dose level of MRG006A recommended for further clinical studies based on assessment of the safety, efficacy and PK data from this study.
Serious Adverse Events (SAEs) - Phase I 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.
Adverse Events (AEs) - Phase I 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 whether or not the event is considered related to the study drug.
Objective Response Rate (ORR)- Phase II Baseline to study completion (up to 24 months). ORR is defined as the proportion of subjects with CR and PR assessed by IRC and investigator according to RECIST v1.1 and mRECIST（HCC patients）. And determine the objective response rate (CR + PR) and its 95% confidence interval.
- Secondary Outcome Measures
Name Time Method Overall Survive (OS)- Phase II Baseline to study completion (up to 24 months). The time from start of study treatment to date of death as a result of any cause.
Incidence of anti-drug antibody (ADA) Baseline to 30 days after the last dose of study treatment. The proportion of patients with positive ADA results.
Duration of Response (DoR) Baseline to study completion (up to 24 months). The time interval between the date of the earliest qualifying response and the date of disease progression or death for any cause, whichever occurs earlier.
QT interval corrected by Fridericia's formula（QTcF） Baseline to 15 days after the third dose of study treatment. Evaluate the effect of MRG006A on the prolongation of QT interval corrected by heart rate using Fridericia's formula (QTcF) in patients with advanced solid tumors.
Objective Response Rate (ORR) - Phase I Baseline to study completion (up to 24 months). ORR is defined as the proportion of subjects with CR and PR assessed by IRC and investigator according to RECIST v1.1 and mRECIST（HCC patients）. And determine the objective response rate (CR + PR) and its 95% confidence interval.
Cmax Baseline to 30 days after the last dose of study treatment. Maximum observed blood concentration
Adverse Events (AEs) - Phase II 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 whether or not the event is considered related to the study drug.
Disease Control Rate (DCR) Baseline to study completion (up to 24 months). The proportion of patients who achieve CR, PR, or stable disease (SD) after treatment.
Progression Free Survival (PFS) Baseline to study completion (up to 24 months). The time from the date of first study dose to disease progression or death whichever occurs first.
Tmax Baseline to 30 days after the last dose of study treatment. Time to reach the maximum blood concentration.
AUC0-t Baseline to 30 days after the last dose of study treatment. Area under the blood concentration-time curve from time 0 to the time of last quantifiable concentration.
Serious Adverse Events (SAEs) - Phase II 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.
