Brief summary
This was a multicenter, multi-reader, open-label, Phase 2 study assessing the safety and performance characteristics of MIP 1404 imaging in the detection of prostate gland and pelvic lymph node cancer. Comparative performance characteristics between MIP 1404 imaging and MRI were also assessed, as judged by histopathology results.
Detailed description
This is a single arm, open label study of approximately 100 high-risk prostate cancer patients scheduled for prostatectomy and extended pelvic lymph node dissection. Patients receive a single IV dose of 99mTc-MIP-1404 (study drug) followed by SPECT/CT scan 3-6 hours after injection. As standard of care, patients will undergo prostatectomy and extended pelvic lymph node dissection (EPLND) within three weeks of study drug dosing. 99mTc-MIP-1404 image data will be evaluated for visible uptake and compared with histopathology.
Interventions
A single dose of 20 ±3 mCi intravenous (IV) injection of 99mTc-MIP-1404

Outcome results
Assess the Ability of 99mTc-MIP-1404 to Detect Prostate Cancer Within the Prostate Gland.
For the prostate gland, sensitivity values refer to the number of subjects in the study, i.e., the percentages of true positive subjects correctly identified by the imaging technique. Pathology results were used as the truth standard for all imaging analyses.
Time frame: Within 3-6 hours of dosing SPECT/CT images will be taken
Population: The primary analysis population is defined as all subjects who completed prostate and lymph node SPECT/CT MIP-1404 imaging, underwent EPLND, and had histopathology results. This population is one less than the safety population (n=105)
