* 2. males or females, ages ≥18 to ≤70 years；
* 3. Patients with advanced solid tumors confirmed by histopathology and/or cytology, who are ineffective or unable to tolerate standard treatment, or who have no standard effective treatment plan (preferred target tumors such as colorectal cancer, gastric cancer, esophageal cancer, pancreatic cancer, small cell lung cancer, soft tissue sarcoma, cervical cancer, etc.);
* 4. At least one measurable lesion (according to RECIST 1.1 criteria);
* 5.ECOG \< 2;
* 6.

* 8. Electrolyte disturbances with clinical significance judged by the researcher still existed before study administration;
* 9. Severe gastrointestinal disorders (such as gastrointestinal bleeding, infection, chronic enteritis, obstruction, or CTCAE grade 1 or above diarrhea) at the time of screening;lts for drug.
* 10.A past or ongoing history of neuropathy or mental disorder (including epilepsy or dementia);
* 11.Patients with other major organ diseases (such as nervous system, cardiovascular system, urinary system, digestive system, respiratory system, rheumatic immune system or metabolic and endocrine system diseases) who are not suitable for inclusion;
* 12.Homozygous mutation of UGT1A1\*28 allele (UGT1A1 TA 7/7 genotype)- Only for the dose escalation phase;
* 13.Previous irinotecan treatment;
* 14.Received systemic antitumor therapy (including radiotherapy, chemotherapy or other treatment) within 4 weeks prior to the first administration of study drug;
* 15.CYP3A4 strong inducers (phenytoin or carbamazepine, barbiturates, ripfampicin, or ripapentine, hypericum perforatum, etc.) have been used in the concomitant medication or within 14 days prior to treatment with the experimental drug;
* 16.CYP3A4 strong inhibitors (clarithromycin, ketoconazole or itraconazole, indenavir, lopinavir, nafazoldone, nerfinavir, ritonavir, saquinavir, terapivir, voriconazole, etc.) have been used in the concomitant medication or within 14 days before treatment with the experimental drug;
* 17.The use of UGT1A1 strong inhibitors (azanavir, gefirozil, indinavir, etc.) within 14 days prior to the treatment with the experimental drug.
