Carbon Nanoparticle-Loaded Iron [CNSI-Fe(II)] in the Treatment of Advanced Solid Tumor

The trial comprises a treatment period, including the DLT evaluation period with a duration of 21 days, and a maintenance treatment period. If the subject completes DLT evaluation without intolerable toxicity, an additional dose may be administered based on the investigator's determination of the benefits outweighing the risks. The original protocol planned for three dose groups: 30 mg, 60 mg, and 90 mg. The protocol was amended on March 28, 2024, to add 120 mg and 150 mg dose groups. A single tumor lesion amenable to intratumoral injection will be selected, regardless of tumor size, number, or location. The drug should be administered at the dose specified for the current dose cohort. The injection volume should be adjusted based on the size of the injected lesion.

The dosing regimen is the same as that for the 30 mg, 60 mg, and 90 mg dose groups. Additionally, if a single lesion cannot accommodate the full corresponding dose of the investigational drug, additional lesions may be selected for simultaneous injection. When multiple lesions are injected, the drug distribution should be allocated proportionally according to the size of each lesion or determined based on the investigator's assessment of an appropriate distribution.
