Clinical Application of Lutetium [177Lu]-Catalase in Tumor Radionuclide Therapy

Early Phase 1

Recruiting

• Conditions: Advanced Malignant Neoplasm
• Interventions: Drug: [ Lu-177]-Catalase

• Registration Number: NCT05985278
• Lead Sponsor: Peking University Cancer Hospital & Institute

Brief Summary

The purpose of this study is to evaluate the retention in tumour and distribution behavior of \[Lu-177\]-Catalase after intratumoral injection,and preliminary evaluation the efficacy and safety of \[Lu-177\]-Catalase.

Detailed Description

After being informed about the study and potential risks, all patients giving written informed consent will undergo a 2-week screening period to determine eligibility for study entry. At day1, patients who meet the eligibility requirements will be intratumoral injection the \[Lu-177\]-Catalase.The efficacy evaluation will be conducted at one month p.i., whether to continue intratumoral injection the \[Lu-177\]-Catalase, depending on the patient's efficacy and safety results.

Inclusion Criteria

1. Male or female patients, aged 18-70 years; ECOG score 0 or 1;
2. Patients with advanced malignant tumors, such as liver cancer, ovarian cancer, prostate cancer, and so on, clearly diagnosed by pathology and/or cytology;
3. Patients with advanced solid tumors who have failed or cannot tolerate standard treatment;
4. Expected survival of more than 3 months;
