Clinical Trial Summary

The purpose of this study is to evaluate the safety and tolerability of MASCT-I in patients with metastatic or recurrent solid tumors who failed standard therapy.

Description:

The study is divided into two stages. The first stage is divided into two groups, both of which adopted 3+3 design. The first group is given MASCT-I by administration method 1, and the second group is given by method 2. One of the administration method will be used in the second stage according to DLT and adverse events found in the first stage.

Patients with potential fertility need to use a medically approved contraceptive measure (such as intrauterine device, contraceptive pill or condom) during the study treatment period and within 3 months after the end of the study treatment period; The serum or urine HCG test must be negative within 7 days before the study was included; And must be non lactating.

Exclusion Criteria:

• 1. Organ transplanters;
• 2. Allergic to sodium citrate or human albumin;
• 3. Patients who have undergone major surgery within 30 days before 1st apheresis (according to the investigator's definition);
