For Part 2, it is mandatory to collect archival tumor tissue sample (preferably 12 with a minimum number of 10 sections) performed within 6 months prior to consent or fresh tumor tissue sample at Biomarker-screening or screening visit
• Exclusion Criteria：
• Any other malignancy within 2 years prior to the first dose of the study treatment except for localized cancers that are considered to have been cured and in the opinion of the Investigator present a low risk for recurrence (e.g., basal or squamous cell skin cancer, superficial bladder cancer, or carcinoma in situ of the prostate, cervix or breast)
• Participants with symptomatic central nervous system (CNS) metastases, or CNS metastases requiring CNS-directed local therapy (such as radiotherapy or surgery), or CNS metastases requiring corticosteroids therapy within 2 weeks of first dose of study treatment.
• History of bowel obstruction within 3 months prior to the first dose of study treatment.
• Known psychiatric disorder or drug abuse that would interfere the study requirements

• Has not recovered (i.e., to Grade 1 or to baseline) from previous anticancer therapy-induced AEs.
• Participant is currently participating or has participated in a study of an investigational agent or using an investigational device within 4 weeks of first dose of SIM0613.
• Major surgery within 2 weeks of receiving the first dose of study treatment (minor procedures such as mediastinoscopy, insertion of a central venous access device, insertion of a feeding tube, needle biopsy and percutaneous nephrostomy are not considered major surgery)
• Prior exposure to topoisomerase I (TOP-I) inhibitor inhibitor-based antibody-drug conjugate (ADC) therapies or LRRC15-targeted therapies.
