Eligibility Criteria

Eligibility Criteria

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Experimental: 177Lu-NYM032 injection
Drug: 177Lu-NYM032 injection
Radionuclide 177Lu will be used as a therapeutic nuclide for this study. The precursor of NYM032 will be labeled with 177Lu to form the chelation product, 177Lu-NYM032 injection which will be used in this study as a intravenous injection dose of 177Lu-NYM032. The radiation dose is chosen within the range of 50-200 mCi for an individual patient at every dose.

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: 28 days
Dose limiting toxicity is determined by monitoring for adverse events following therapy.
28 days
Maximum Tolerated Dose (MTD)
Time Frame: 28 days
Maximum tolerated dose (MTD) is determined by monitoring dose-limiting toxicity and adverse events in the dosing cohorts
