Study Overview

Phase I Study to evaluate124I-A11 PSCA Minibody in Patients With Metastatic Prostate, Bladder and Pancreatic Cancer

The purpose of the study is to determine whether positron emission tomography (PET), using the new imaging drug [124 I] PSCA-Minibody can be used for imaging prostate, pancreatic or bladder cancer that has spread to the bones and soft tissues (e.g., lymph nodes, lungs, etc.). The PET imaging drug tested in this study binds to the cell marker called Prostate Stem Cell Antigen (PSCA), which is present on certain prostate, pancreatic and bladder cancers.

The people doing this study want to find out: 1. Can the [124 I] PSCA-Minibody be used to image prostate, pancreatic and bladder cancer? 2. How much of the PSCA Minibody needs to be used to see the prostate, pancreatic or bladder cancer? 3. Does the PSCA Minibody see more/same/fewer lesions than are identified on traditional scans such as bone scan or CT scan? To answer these questions, we want to evaluate how [124 I] PSCA-Minibody is distributed throughout the body in 20 patients with prostate, pancreatic or bladder cancer. This is done with PET/CT imaging. A PET/CT scan is a non-invasive x-ray test that uses a special camera to take pictures of the inside of your body. It can "see" the radiation given off by tiny particles called positrons in the radioactive drug injected into you while also taking pictures of the organs within the body. For this study the radioactive substance is [124 I] PSCA-Minibody. The scanning for this study is done with an imaging procedure in the department of Nuclear Medicine during which the experimental drug [124 I] PSCA-Minibody will be administered by intravenous (i.v.) infusion. An experimental drug is one that is not yet approved by the US Food and Drug Administration (FDA). [124 I] PSCA-Minibody is a combination of a monoclonal antibody, and I-124, a radioactive type of iodine. The iodine will make the antibody and the cancer cells visible in a PET scan. PET stands for positron emission tomography and uses radioactivity to image the inside of the body. A CT scan uses x-rays to look at the internal organs in the body. This study will use a combination PET/CT to look at the cancer cells in your body that have taken up the study agent as well as to see their location in your body.

Arms and Interventions

Participant Group/ArmIntervention/Treatment
EXPERIMENTAL: All patients

Patients will receive one intravenous dose of 4 mg, 20mg or 40 mg of A11 minibody labeled with 5 mCi (185 MBq) of 124I, followed by [124I] PSCA-Minibody PET/CT imaging of the whole body.

RADIATION: [124I] PSCA-Minibody PET/CT imaging of the whole body

  • Whole body Imaging
Primary Outcome MeasuresMeasure DescriptionTime Frame
Assess the safety of [124I] PSCA-MinibodySafety measures: adverse events including laboratory adverse events will be graded and summarized according to the National Cancer Institute CTCAE, version 4.03. * Laboratory tests (CBC with differential, platelets, serum electrolytes, BUN, creatinine, chemistry, urine analysis) * Vital signs (upright and supine blood pressure, heart rate, respiratory rate, oral temperature, and weight) * Physical examination * HAMBA tier in serumup to 3 months
Secondary Outcome MeasuresMeasure DescriptionTime Frame
Assess the ability of [124I] PSCA-Minibody to image known metastatic diseaseBinary qualitative reading of [124I] PSCA-Minibody based PET imaging in subjects with known metastatic prostate, pancreatic, or bladder cancer to decide on the presence or absence of targeting to this cancer.1 Day of scan
Compare the sensitivity and specificity of [124I] PSCA-Minibody with conventional imagingNumber, localization and size of metastatic lesions by 124I-A11 based PET/CT imaging and comparison to standard of care imaging with CT and bone scan.1 Day of scan

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.

Ages Eligible for Study:
ALL

Sexes Eligible for Study:
18 Years

Accepts Healthy Volunteers:

    Inclusion Criteria (subjects must meet all of the following criteria in order to be enrolled in this study):

Evidence of recurrent metastatic disease demonstrated by an abnormal bone scan, CT scan or MRI, or FDG-PET within 6 weeks (with no new interval treatment before imaging trial) 3. Expected survival ≤ 6 months 4. Provide written informed consent and willing to comply with protocol requirement 5. ≥ 18 years of age 6. The following laboratory results should be within the following limits within 4 weeks prior to study day 1:

Aspartate amino transaminase (AST) ≤ 2.5 x ULN 6. Alanine aminotransferase (ALT) ≤ 2.5 x ULN 7. Serum creatinine ≤ 2.0 mg/dl (calculated creatinine clearance > 45 ml/min) 7. Able to undergo imaging studies, as well as conventional bone and body imaging, as well as 124I-A11 PSCA minibody experimental scan.
    Exclusion Criteria (subjects meeting any of the following criteria will not be enrolled in this study):
    1. Inadequate venous access (two antecubital or equivalent venous access sites) 2. Administration of a radionuclide within 5 physical half-lives prior to projected administration of 124I-A11 PSCA minibody 3. New York Heart Association Class III/IV cardiac disease. 4.

Subjects weighing ≥ 350 lbs or are unable to fit in the imaging gantry 7. Any other condition or personal circumstance that, in the judgment of the investigator, might interfere with the collection of complete good quality data. 8. Iodine Allergy, hyperthyroidism, or Grave's disease. 9. Any other disease or medical or psychiatric condition or laboratory abnormality that may increase the risk associated with study participation or investigational product administration or may interfere with the interpretation of study results and, in the judgment of the investigator, would make the participant inappropriate for entry into this study.
