Safety, Tolerability, and Immunogenicity of LK101 Alone in Participants With Incurable Solid Tumors

Summary

This is an open-labeled, single-center phase I study in patients with incurable advanced solid tumors, who failed with all previous standard therapy. The aim is to observe and evaluate the safety, tolerability, and immunogenicity of LK101 injection.

Eligibility

Inclusion Criteria:

* signed informed consent.
* Age 18-75.
* life expectancy ≥3 months.
* Eastern Cooperative Oncology Group (ECOG) Performance Status of 0 or 1.
* Subjects with histologically or cytologically confirmed advanced or metastatic solid tumors, unresponsive to standard treatment or for whom no standard treatment is available or appropriate.
* The sequencing of the tumor was qualified.
* Subject must have measurable diseases as per RECIST v1.1 criteria.
* According to the investigator's judgment, venous vascular conditions can meet the needs of apheresis.
* Adequate bone marrow, renal, and hepatic at screening and at Baseline.

Exclusion Criteria:

* Patients who have received therapeutic tumor vaccine products (including peptide vaccine, mRNA vaccine, DC vaccine, etc.).
* Diagnosis of malignant diseases other than study disease within 5 years before screening (except for malignant tumors that can be expected to recover after treatment).
* Patients received systemic antitumor treatment within 2 weeks before the apheresis, or receive research drugs or device therapy.
* Received radiotherapy within 4 weeks prior to screening.
* Toxicity caused by previous treatment did not recover to CTCAE (version 5.0) Grade 1 or below (except hair loss and peripheral neuropathy).
* Patients who have active brain metastases or cancerous meningitis.
* History of significant cardiovascular and cerebrovascular disease occurred in the 6 months prior to screening, Any of the following cardiac criteria:

  * Mean resting corrected QT interval (QTc) \> 470 ms;
  * Left ventricular ejection fraction (LVEF) ≤ 50%;
  * American New York heart association (NYHA) heart function ≥ 2 or higher;
  * serious arrhythmia;
  * poorly controlled hypertension;
  * other serious heart diseases;
  * Patients with interstitial pneumonia, except those inactive and do not require hormone therapy disease;
* Any of the following test results are positive: human immunodeficiency virus (HIV) antibody, treponema pallidum antibody, hepatitis C virus (HCV) antibody, hepatitis B virus (HBV) surface antigen (HBsAg), HBV DNA and novel coronavirus nucleic acid.
* Active tuberculosis (TB) during screening.
* Treatment with systemic steroids or other immunosuppressive agents within 14 days prior to screening;
* Vaccination within 4 weeks prior to screening.
* Major injuries and/or surgery =\< 4 weeks prior to screening.
* Persons with a history of psychotropic substance abuse and inability to abstain or with a history of mental disorders.
