Technetium [99mTc]-H7ND injection to detect peritoneal metastasis in gastrointestinal cancer

A Multicenter, Open-access, Self-controlled Phase II Clinical Study to Evaluate the Efficacy and Safety of Technetium [99mTc]-H7ND Injection in the Diagnosis of Peritoneal Metastasis of Gastrointestinal Malignancies.

PHASE2 · Jiaxing Pharmadax Genesis Pharmaceutical Technology Co.,Ltd. · NCT07107633

This trial will test whether a technetium [99mTc]-H7ND injection can help detect peritoneal metastases in adults with confirmed gastrointestinal cancers who are scheduled for surgical exploration.

What this trial studies

This Phase II interventional study gives a radiolabeled tracer, technetium [99mTc]-H7ND, to adults with histologically confirmed gastrointestinal malignancies who are planned for surgical removal or exploration. Participants will receive the injection prior to surgery and imaging findings will be compared to intraoperative and pathological results to determine diagnostic performance and an optimal threshold for tracer uptake. Safety outcomes and adverse events related to the radiotracer will be recorded throughout the study period. The trial aims to define both how well the tracer detects peritoneal disease and whether it is safe in this patient population.

Who should consider this trial

Good fit: Adults (≥18 years) with histologically or cytologically confirmed gastrointestinal malignancy who are scheduled for surgical exploration or resection and can provide informed consent are the intended candidates.

Not a fit: Patients who are not surgical candidates, have non-gastrointestinal primary tumors, are pregnant, or cannot receive a radiotracer are unlikely to benefit from this diagnostic approach.

Why it matters

Potential benefit: If successful, the tracer could improve detection of peritoneal metastases and help guide surgical decision-making and staging for patients with gastrointestinal cancer.

How similar studies have performed: Related radiotracer imaging approaches for peritoneal disease have shown mixed results in prior work, and the specific 99mTc-H7ND tracer appears to be a novel agent with limited prior clinical data.
