ClinConnect Summary

This clinical trial is studying a new injection called INR101, which is being tested for its effectiveness in helping doctors see images of prostate cancer using a special type of scan called PET/CT imaging. The goal is to improve how prostate cancer is diagnosed and monitored, which can be very important for treating patients effectively.

To be eligible for this trial, participants must be males aged 18 or older who have been diagnosed with prostate cancer and are planning to have surgery to remove the prostate. They should be in relatively good health, as indicated by specific tests, and must agree to use contraceptive measures during the trial period. The trial is not yet recruiting participants, but once it begins, those who join can expect to receive the INR101 injection and undergo imaging tests to see how well the treatment works in visualizing their cancer. It’s important for potential participants to understand the trial's purpose and procedures, and they will need to sign a consent form to take part.

Eligibility criteria

• Inclusion Criteria:
• • 1. Males aged ≥18 years old
• • 2. ECOG score of 0 or 1
• • 3. Participants confirmed as prostate adenocarcinoma by histological pathological diagnosis before surgery, and meets the diagnostic criteria for intermediate-risk and above localized prostate cancer in the 2023 CSCO (Chinese Society of Clinical Oncology) guidelines (clinical T stage ≥ T2b; or PSA \> 10 ng/mL; or Gleason \> 6 score)
• • 4. Intended to undergo radical prostatectomy accompanied by pelvic lymph node dissection
• 5. Routine blood tests, liver and kidney function, and coagulation function meet the corresponding conditions:
• • Platelet count \> 100×10⁹/L.
• • Blood urea nitrogen/urea and serum creatinine ≤ 1.5 x ULN.
• • AST, ALT, and ALP ≤ 2.5 x ULN.
• • Total bilirubin≤ 1.5 x ULN.
• • PT and APTT≤ 1.5 x ULN.
• • 6. Life expectancy of at least 6 months as assessed by investigator
• • 7. Agree to use contraceptive measures from the date of signing the informed consent form to 3 months after medication administration, and avoid sperm donation
• • 8. The participant/legal authorized representative understands the purpose and procedures of the trial and signs the informed consent form
• Exclusion Criteria:
• • 1. Participants who are unable to complete the imaging as required
• • 2. Having had ≥ 2 types of malignant tumors within 5 years prior to the first administration, with the exception of fully treated non-metastatic thyroid cancer, basal cell carcinoma of the skin, superficial squamous cell carcinoma of the skin, and superficial bladder cancer.
• • 3. Participants who have previously received, are currently receiving, or plan to receive (from the signing of the informed consent form until the acquisition of the pathological sample) androgen deprivation therapy or any anti-tumor therapy such as radiotherapy, chemotherapy, or endocrine therapy during the trial period.
• • 4. Participants in other interventional clinical trials and within 5 half-lives of the investigational medicinal product or participants in other interventional clinical trials before signing the informed consent form; or participants in clinical trials of radioactive therapeutic drugs before signing the informed consent form and the time from the drug withdrawal to the signing date of the informed consent form is less than 3 months.
• • 5. Have received intravenous iodine contrast agent within 24 hours prior to the administration of INR101, or have received any high-density oral contrast agent within 5 days (except for those who, as judged by the investigator, have no residual contrast agent in the intestines; oral water-soluble contrast agents are acceptable).
• • 6. Participants with a history of salivary gland diseases or Paget's disease
• • 7. Participants with hip joint prostheses
• • 8. Known allergy to the active ingredients of INR101 or its components
• • 9. Serum virology examination, including positive treponema pallidum antibody, positive HIV antibody, positive hepatitis C antibody with positive hepatitis C virus ribonucleic acid (HCV RNA), or active hepatitis B (for those with positive hepatitis B surface antigen, hepatitis B virus deoxyribonucleic acid (HBV DNA) needs to be detected, and if the HBV DNA is positive). (Note: If the investigator assesses and determines that active hepatitis B is not a contraindication for surgery, the participant may be enrolled in the study.)
• • 10. Investigators judge that there are any medical diseases or other conditions that may affect safety, compliance or may affect the study results.
