This is an investigator-initiated trial aimed at evaluating the safety and preliminary efficacy of a novel red blood cell-based therapy, where engineered red blood cells are conjugated with checkpoint inhibitors.
The present study has 2 parts,including dose escalation and dose expansion。The dose escalation part is carried out according to the "3+3" increasing principle. At least four dose groups are predefined based on the number of engineered red blood cells, specifically 1e11, 2e11, 3e11, 3.5e11,etc. Dose expansion part will be decided according to dose escalation part.

RECRUITINGNumber of Participants Experiencing Dose-Limiting Toxicities (DLTs) According to National Cancer Institute Common Terminology Criteria for Adverse Events Version 5.0 (NCI-CTCAE v.5.0) in Participants in escalating part.
DLTs were assessed according to NCI-CTCAE v.5.0 during the first cycle (21 days) and were defined as occurrence of any of the following toxicities if judged by the investigator to be possibly, probably or definitely related to study drug administration。
Time frame: 21 days
Number of Participants Who Experienced an Adverse Event (AE)
An AE was defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the Sponsor's product, whether or not considered related to the use of the product. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a pre-existing condition which was temporally associated with the use of the Sponsor's product was also an AE. The number of participants who experienced an AE was reported for all patients.
Time frame: Up to approximately 24 months
Overall Response Rate (ORR) According to Response Evaluation Criteria In Solid Tumors Version 1.1 (RECIST 1.1)
ORR was defined as the percentage of participants in the analysis population who had a confirmed Complete Response (CR: disappearance of all lesions) or Partial Response (PR: at least a 30% decrease in the sum of diameters \[SOD\] of target lesions, taking as reference the baseline SOD) according to RECIST 1.1(only for solid tumor) or Lugano2014( only for lymphomas)
Time frame: per 6 weeks
Anti-drug antibody (ADA)
Describe the number and percentage of anti-drug antibodies (ADA) produced by subjects at each time point after treatment, and the time of producing ADA.
Time frame: 1 year
Maximum Concentration (Cmax) of engineered red blood cells in all Participants
This platform is for informational purposes only and does not constitute medical advice. Always consult a qualified healthcare professional.
Blood samples were collected at specified intervals for the determination of Cmax. Cmax was defined as the maximum concentration of engineered red blood cells reached. Cmax was based on noncompartmental analysis and reported for all participants
Time frame: Cycle 1: Pre-dose, post-dose at 0.5, 6 and 12 hours and Days 2, 3, 8 and 15
Time to Maximum Concentration (Tmax) f engineered red blood cells in all Participants
Blood samples were collected at specified intervals for the determination of Tmax. Tmax was defined as time to the maximum concentration of engineered red blood cells reached. Tmax was based on noncompartmental analysis and reported for all participants
Time frame: Cycle 1: Pre-dose, post-dose at 0.5, 6 and 12 hours and Days 2, 3, 8 and 15
