Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Active, not recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This first-in-human, dose escalation and dose expansion study is to evaluate the safety, tolerability, pharmacokinetics (PK), immunogenicity, pharmacodynamics (PD) and anti-tumor activity of MHB036C in patients with advanced solid tumor. The Phase I stage is to determine the maximum tolerated dose (MTD). The phase II stage is to determine the recommended Phase 2 dose (RP2D) according to safety and efficacy in specific tumor types.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Participants voluntarily agree to participate in the study and sign the Informed Consent Form (ICF).

  • Participants with Eastern Cooperative Oncology Group performance score of 0-1.
  • Participants with expected survival time of more than 3 months.
  • Eligible participants of childbearing potential (males and females) must agree to take reliable contraceptive measures (hormone or barrier method, or absolute abstinence, etc.) with their partners during the study and within at least 90 days after the last dose; female participants of childbearing potential must have a negative results of blood pregnancy test within 7 days before the first dose of the investigational product, and must be non-lactating.
  • Participants who are able to understand study requirements, and willing and able to comply with arrangements of study and follow-up procedures.

  • Participants who have received chemotherapy within 3 weeks prior to the first dose of investigational product, or have received anti-tumor therapy including radiation therapy, biologic therapy, endocrine therapy, immunotherapy, etc. within 4 weeks prior to the first dose; or participants with the following conditions:

    • Medication of nitrosourea or mitomycin C within 6 weeks prior to the first dose of MHB036C;

  • Medication of other disapproved investigational products or therapies within 4 weeks prior to the first dose of investigational product.
  • Presence of brain metastases and/or carcinomatous meningitis. Participants previously treated for brain metastases may be considered to be enrolled in this study, provided they have been in stable condition for at least 4 weeks, no evidence of new or enlarging brain metastases, or without steroid therapy within 14 days prior to the first dose of investigational product. This exception does not include carcinomatous meningitis, which should be excluded regardless of clinical stability.
  • Participants previously received same targeted therapy will be excluded.
  • Participants with adverse reactions from previous anti-tumor therapy that have not recovered to ≤Grade 1 as per CTCAE 5.0 (except for toxicities without safety risks as determined by the investigator, such as alopecia, hypothyroidism stably managed by hormone replacement therapy, etc.).

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Incidence of participants with adverse events (AE)
Time Frame: Until 30 days after last dose of MHB036C
An AE is defined as any untoward medical occurrence in a participant administered a pharmaceutical product temporally associated with the use of study treatment, whether or not considered related to the study treatment.
Until 30 days after last dose of MHB036C
Number of participants with dose-limiting toxicity (DLT)
Time Frame: At the end of Cycle 1 (each cycle is 21 days)
DLTs will be assessed during the dose-escalation phase and are defined as toxicities related to MHB036C which meet pre-defined severity criteria and occurs within the first cycle of treatment
At the end of Cycle 1 (each cycle is 21 days)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Maximum Plasma Concentration (Cmax)
Time Frame: Until 30 days after last dose of MHB036C
To analysis the serum concentrations at different timepoints to determine the Cmax
Until 30 days after last dose of MHB036C
The area under the plasma concentration-time curve (AUC)
Time Frame: Until 30 days after last dose of MHB036C
To analysis the serum concentrations at different timepoints to determine the AUC
Until 30 days after last dose of MHB036C
To detectable anti-drug antibodies with treated subjects
Time Frame: Until 30 days after last dose of MHB036C
The immunogenicity of MHB036C will be assessed by the number of subjects who produce anti-drug antibodies (ADAs)
Until 30 days after last dose of MHB036C
Objective response rate (ORR)
Time Frame: Until 30 days after last dose of MHB036C
The ORR is defined as the proportion of subjects with confirmed complete remission (CR) or confirmed partial response (PR), based on RECIST Version 1.1.
