Lead Sponsor:
Sun Yat-sen University
Conditions:
Solid Tumor
Advanced Cancer
Eligibility:
All Genders
18-75 years
Phase:
PHASE2
Brief Summary
The purpose of this study is to evaluate the response of toripalimab (JS001), a PD1 antibody, in participants with POLE or POLD-mutated and non microsatellite instability (non-MSI-H) advanced solid ca...
Detailed Description
Immune checkpoint inhibitor (ICI) therapy including antibodies targeting PD-1/PD-L1 or CTLA-4 has greatly advanced the cancer treatments. Recent studies have identified several predictive markers for ...
Eligibility Criteria
Inclusion

- Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤ 2.5 x (5 x in participants with liver metastasis) upper limit of normal (ULN)
- Albumin ≥ 3 g/dL
- Alkaline phosphatase ≤ 2.5 x ULN.
- Serum bilirubin \<1.5 mg/dL
- Creatinine ≤ ULN.
- Absolute neutrophil count ≥ 1.5X10E9/L
- Platelets ≥ 100 x 10E9/L
- Hemoglobin ≥ 90 g/L
- For females of childbearing potential (defined as \<2 years after last menstruation or not surgically sterile), a negative serum pregnancy test must be performed within 21 days of the first dose of study treatment.
- For females: agreement to contraception during the study treatment period and for at least 28 days after the last dose of study treatment
Exclusion
- Patients with confirmed or suspected brain metastases
- Patients with cancerous meningitis
- Patients without germline mutations or somatic mutations in POLE and POLD
- MSI-H (microsatellite instability-high) or dMMR
- Prior treatment with PD-1 inhibitors, PD-L1 inhibitors or CTLA-4 inhibitors (or other inhibitors in T cell co-stimulatory signals or checkpoint pathways)
- Known history or evidence of cytotoxic drug therapy, biologic drug therapy (such as monoclonal antibodies), immunotherapy (such as interleukin 2 or interferon), or other investigational drugs therapy in the 4 weeks before the first dose of study treatment
- Known history or evidence of significant immunodeficiency (including but not limited to: interstitial pneumonia, uveitis, enteritis, hepatitis, pituitary inflammation, nephritis, hyperthyroidism and hypothyroidism; Patients with vitiligo or asthma completely relieved can be included. Asthma that requires medical intervention cannot be included)
- Patients with a condition requiring systemic treatment with either corticosteroids (\> 10 mg daily prednisolone equivalent) or other immunosuppressive medications
- Patients with active tuberculosis. Known history of antituberculosis drugs treatment in 1 year before the first dose of study treatment
- Administration of an anti-infection vaccine (e.g. influenza vaccine, chickenpox vaccine) in the 4 weeks before the first dose of study treatment
- Symptomatic heart failure, coronary heart disease (CHD), myocardial infarction in the 6 months before the first dose of study treatment
- Known allergy to JS001 or its excipients
- Pregnant or breastfeeding females
- Other prior malignancy active within the previous 5 years except for non-melanoma skin cancer
- Persons without legal capacity
- Positive test for HIV or AIDS
