Description

Inclusion Criteria:

1. The expected survival time is not less than 3 months.
2. Clinical performance status of Eastern Cooperative Oncology Group (ECOG) 0-1.
3. Patients with advanced solid tumors confirmed by histology or cytology: advanced Melanoma, cervical cancer/ovarian cancer, head and neck squamous cell cancer, non-small cell lung cancer, esophageal cancer and other solid tumors that have failed standard treatment regimens, cannot tolerate standard treatment, refuse or do not have standard treatment regimens available.
4. The patient has lesions that can be used for surgical resection (>1.5 cm3) or biopsy puncture (no less than 6 lesions) for LM103 manufacturing.
5. At least one measurable lesion as the target lesion after collecting tumor tissue from the patient (RECIST v1.1 criteria).
6. Laboratory tests results during the screening period indicate that the subjects have sufficient organ function.

Exclusion Criteria:

1. Have a medical history of other malignant tumors other than the disease under study in the past 5 years, except for malignant tumors that can be expected to recover after treatment (including but not limited to thyroid cancer, cervical Carcinoma in situ, basal or squamous cell skin cancer or Ductal carcinoma in situ of the breast treated by radical surgery).
2. LM103 received systematic therapy of antineoplastic drugs (including chemotherapy, small molecule targeted drug therapy, Hormone replacement therapy, etc.), or local antineoplastic therapy (such as radiotherapy, palliative radiotherapy for bone metastases>2 weeks before the start of the study and intracranial stereotactic radiotherapy or resection of a single brain metastasis>3 weeks before the start of the study were acceptable) within 4 weeks before LM103 infusion; Or received clinical investigational drugs or equipment treatment.
3. Adverse reactions caused by previous treatment have not recovered to CTCAE (version 5.0) level 1 or below (excluding hair loss and neurotoxicity, which have been determined by the researchers to be irreparable and level 2 hypothyroidism for a long time).
4. Previously received allogeneic hematopoietic stem cell transplantation or solid organ transplantation.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Adverse events (AE), Serious adverse event (SAE) and immune related adverse events (irAE)	Incidence and severity of AE, SAE and irAE; Abnormal changes in laboratory and other tests with clinical significance.	through study completion, an average of 1 year estimate

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Objective response rate (ORR)	The Objective Response Rate (ORR) was defined as the percentage of participants who achieved a best overall response of confirmed Complete Response (CR) or Partial Response (PR), assessed by investigator assessment based on RECIST version 1.1.	through study completion, an average of 1 year estimate
Duration of response (DOR)	Duration of Response (DOR) was defined as the time from the date of the first documentation of objective response (complete response [CR] or partial response [PR]) to the date of the first objective documentation of progressive disease (PD) or death due to any cause.	through study completion, an average of 1 year estimate
Disease control rate (DCR)	Disease control rate (DCR) was defined as the percentage of participants with a best overall response of CR, PR or SD as defined by RECIST version 1.1.	through study completion, an average of 1 year estimate
Time to disease progression (TTP)	Time to progression (TTP) is defined as the interval between the date of randomization and the earliest date of progression of disease (PD) or death due to the solid tomor.	through study completion, an average of 1 year estimate
Progression free survival (PFS)	Progression-free survival (PFS) was defined as the time from the date of enrollment to the earlier of the dates of the first objective documentation of disease progression (as per RECIST version 1.1) or death due to any cause.	through study completion, an average of 1 year estimate
Overall survival (OS)	OS was defined as the time from first dose to date of death from any cause.	through study completion, an average of 1 year estimate
Time to response (TTR)	Time to progression (TTP) is defined as the interval between the date of randomization and the earliest date of progression of disease (PD) or death due to the solid tomor.	through study completion, an average of 1 year estimate
