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

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Estimated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

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

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Biopsy proven HER2-positive or HER2-low primary malignancy or metastatic disease

Note: HER2 positivity is defined according to American Society of Clinical Oncology guidelines or ERBB2 amplification on next generation sequencing Note: HER2-low is defined as low HER2 expression, with immunohistochemistry (IHC) 1+ or IHC 2+ and in situ hybridization [ISH]-negative, including FISH.

  • Biopsy proven primary malignancy or metastatic disease
  • At least one malignant lesion on CT, MR, or FDG PET/CT within 60 days of protocol enrollment
  • Age 18 years or greater
  • ECOG performance of 0-2

Exclusion Criteria:

  • Creatinine > 2 times normal limit (obtained with 8 weeks of enrollment)
  • AST/ALT > 2 times normal limit (obtained with 8 weeks of enrollment)
  • Life expectancy < 3 months
  • Pregnancy or lactation
  • Patients who cannot undergo PET/CT due to weight limits (over 450 pounds)

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

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: HER2-positive malignancy
Participants will have a diagnosis of HER2-positive malignancy
Combination product: 89Zr-ss-pertuzumab PET/CT
Patients will receive 89Zr-ss-pertuzumab. 89Zr-ss-pertuzumab PET/CT images will be reconstructed using iterative reconstruction and displayed in multiplanar reconstruction. In the event that 89Zr-ss-pertuzumab is unavailable, randomly labelled 89Zr-pertuzumab PET will be allowed to make HER2 PET imaging available for our patients. Once 89Zr-ss-pertuzumab is available, then patients will be imaged with 89Zr-ss-pertuzumab and randomly labelled 89Zr-pertuzumab will no longer be used.
Experimental: HER2-low malignancy
Participants will have a diagnosis of HER2-low malignancy
Combination product: 89Zr-ss-pertuzumab PET/CT
Patients will receive 89Zr-ss-pertuzumab. 89Zr-ss-pertuzumab PET/CT images will be reconstructed using iterative reconstruction and displayed in multiplanar reconstruction. In the event that 89Zr-ss-pertuzumab is unavailable, randomly labelled 89Zr-pertuzumab PET will be allowed to make HER2 PET imaging available for our patients. Once 89Zr-ss-pertuzumab is available, then patients will be imaged with 89Zr-ss-pertuzumab and randomly labelled 89Zr-pertuzumab will no longer be used.

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
