Phase I/IIA Study of PET Imaging With 89Zr-Df-IAB2M in Metastatic Prostate Cancer (IAB2M)

February 10, 2020 updated by: ImaginAb, Inc.

A Phase I/IIA Study of PET Imaging With 89Zr-Df-IAb2M in Patients With Metastatic Prostate Cancer

This is a Phase I/IIa study evaluating the safety and feasibility of [89Zr]Df-IAB2M as an immunoPET tracer for metastatic prostate cancer. Individuals participating in this study will have a FDG PET scan, as well as four (4) PET scans (over a 3 day period) following the injection of [89Zr]Df-IAB2M PET tracer. Three different dosing levels will be explored. The purpose of the study is to demonstrate the safety of [89Zr]Df-IAB2M, ability to detect prostate cancer, and optimal time point and dose level for imaging.

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

IAB2M is an approximately 80 kDA molecular weight antibody fragment (a "Minibody"). Limited (Phase 0/Proof-of-concept) patient experience with this biologic targeting agent has been previously obtained with SPECT imaging Ex-US, demonstrating targeting of soft tissue and bone lesions in advanced metastatic prostate cancer.

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.

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

To assess the safety of a single dose of of [89Zr]Df-IAB2M
Day 1 (Infusion Day) through Day 7

Secondary Outcome Measures

Secondary Outcome Measures

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
