Study to Evaluate the Safety, Pharmacokinetics, Tissue Distribution, Metabolism and Dosimetry of Two Prostate Cancer Imaging Agents

October 7, 2011 updated by: Molecular Insight Pharmaceuticals, Inc.

A Phase I Study Evaluating the Safety, Pharmacokinetics, Tissue Distribution, Metabolism of Small Molecule Inhibitors of Prostate Specific Membrane Antigen: Determination of I-123 Radiation Dosimetry for 123-I-MIP-1072 and 123-I-MIP-1095

This is a single blinded, randomized, cross-over design. Up to 12 patients will be randomly administered a single 10.0 mCi dose of 123I-MIP-1072 or 123I-MIP-1095 (study drugs). The second (alternate) study drug will be administered approximately 14 days after the first. A final follow-up visit will occur approximately 2 weeks after the injection of the alternate study drug.

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.

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

Genders Eligible for Study

Male

    2. PSA> 20 if intact prostate
  • Have platelet count of > 50,000/mm3
  • Have neutrophil count of > 1,000/mm3
  • Provide written informed consent and willing to comply with protocol requirements
  • Greater than or equal to 18 years of age

  • Have any medical condition or other circumstances which, in the opinion of the Investigator, would significantly decrease the chances of obtaining reliable data, achieving study objectives, or completing the study and/or post dose follow-up examinations
  • Is determined by the Investigator that the patient is clinically unsuitable for the study
  • Have had any other malignancies within 5 years other than basal or squamous cell carcinoma of the skin.

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 examine the pharmacokinetics and organ radiation dosimetry of 123-I-MIP-1072 and 123I-MIP-1095 in patients with prior histological diagnosis of prostate cancer with evidence of recurrent metastatic disease.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
To examine whole body excretion and metabolism of 123-I-MIP-1072 and 123-I-MIP-1095 in patients with recurrent metastatic prostate cancer.
To evaluate the safety of administering a 10.0 mCi dose of 123-I-MIP-1072 and 123-I-MIP-1095 to patients with recurrent metastatic prostate cancer.

Primary Completion (Actual)

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.
