Phase II Trial to Investigate the Safety and Efficacy of Three Dosing Regimens of OTL78 Injection

Description

This study is being done to compare how well Zopocianine (OTL78) in combination with Near InfraRed (NIR) fluorescent imaging may improve the detection of malignant (growing in an uncontrolled way) tissue in adult subjects undergoing prostatectomy and lymph node dissection for biopsy confirmed prostate cancer.

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.

For general information about clinical research, read Learn About Studies.

Eligibility Criteria

  • 1. Provision of signed and dated informed consent and HIPAA form
  • 2. Male subjects 18 years of age and older
  • 3. Known primary prostate cancer and Grade Group 3 to 5 (≥ cT3) with one or more of the following:
  • 1. Suspected extraprostatic disease (EPD) (extracapsular extension (ECE) and/or seminal vesicle infiltration (SVI)),
  • 2. 3 or more biopsy cores of grade group 3-5;
  • 3. Suspected lymph node metastasis (clinical stage cN1, or by magnetic resonance imaging (mriN+), or by Prostate Specific Membrane Antigen positron emission tomography (PSMA PET+));
  • 4. Planned to undergo a standard of care robotic prostatectomy and lymph node dissection
  • 5. Ability to understand the requirements of the study and agree to abide by the study restrictions and to return for the required assessments
  • 6. Agree to use a medically acceptable method of birth control (e.g., spermicide in conjunction with a barrier such as a condom) or sexual abstinence for the duration of the study, including through final study visit (6 weeks) after the dose of study drug. Sperm donation is prohibited during the study and for 3 months after the dose of study drug. Female partners must use hormonal or barrier contraception unless postmenopausal or abstinent.
  • 1. The surgeon plans to perform an extraperitoneal approach
  • 2. History of anaphylactic reactions to products containing indocyanine green
  • 3. History of allergy to any of the components of ZOPOCIANINE:
  • 1. 2-\[3-(1,3-dicarboxypropyl)ureido\] pentanedioic acid (DUPA)
  • 2. Polyethylene glycol-dipeptide linker
  • 3. Chlorodye
  • 4. Impaired renal or hepatic function:
  • 1. Renal: creatinine clearance (eGFR) \< 50 mL/min
  • 2. Hepatic: total bilirubin \> 2 × upper limit of normal or ALT/AST \> 3 × upper limit of normal.
  • 5. Patients with QTc interval ≥ 470 msec per electrocardiogram (ECG) at screening.
  • 6. Significant acute or chronic medical, neurologic, or illness in the subject that, in the judgment of the Principal Investigator, could compromise subject safety, limit the ability to complete the study, and/or compromise the objectives of the study
