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

15 subjects will be enrolled in each of the 3 cohorts. Once enrollment of the first 3 of 15 subjects is completed, Safety and Efficacy Review Committee (SERC) meeting involving the study Investigators and the Sponsor's clinical study team will be held after Day 43 (Week 6) visit of the third subject enrolled. After the data from enrolled subjects is reviewed in the meeting, dose escalation to the next dose will be determined, based on the number of subjects experiencing dose-limiting toxicity (DLT).

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. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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

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
Time Frame
Number of participants with adverse events (AEs) as graded by NCI CTCAE
Time Frame: Screening visit, up to 2 years
Screening visit, up to 2 years
Assessment of tumor response of target lesion where RZ-001 is administered based on the RECIST v1.1 and HCC mRECIST
Time Frame: Screening visit, every 2 cycles (each cycle is 3 weeks, 6 weeks) until week 54 & every 3 cycles (each cycle is 3 weeks, 9 weeks) after week 54, up to 2 years
