CAR-DC Vaccine and ICIs in Local Advanced/Metastatic Solid Tumors
China9 participantsStarted 2023-04-03
Plain-language summary
This is a pilot clinical trial for subjects with local advanced/metastatic solid tumors to determine the safety, efficacy and immune response of autologous EphA2-targeting CAR-DC vaccine loaded with KRAS mutant peptide (KRAS-EphA-2-CAR-DC) in combination with ICIs. It aims to: assess the safety and antitumor effects of KRAS-EphA-2-CAR-DC vaccine; detect T cell response against KRAS mutant peptide and tumor neoepitopes after the treatment with KRAS-EphA-2-CAR-DC vaccine and ICIs.

Inclusion criteria
✓. Age 18-75 (inclusive).
✓. ECOG performance status ≤2 and Estimated life expectancy of more than 3 months.
✓. Local advanced/metastatic solid tumors confirmed by histopathology or cytology with documentation of tumor EphA2 positive (≥20%) and KRAS mutation (G12V or G12D or G12C) within 6 months prior to screening. The second malignancy is allowed.
✓. No clinical response to standard frontline therapy, or no standard therapy exists. Patients who have declined standard therapy or have no access to standard therapy may be enrolled and the reasons for lack of access need to be documented. Previous treatment with anti-PD-1/PD-L1 antibodies or anti-CTLA4 antibody are allowed, regardless of the level of PD-1/PD-L1 expression, dMMR and TMB.
✓. At least one measurable lesion at baseline per RECIST version 1.1.
✓. Adequate organ function as defined by the following criteria: ANC ≥1000 cells/μL; Platelet count ≥80,000/μL; Hemoglobin ≥8.0 g/dL; Serum AST and serum ALT, ≤3.0 x ULN (≤5 x ULN for patients with liver metastases); Total serum bilirubin ≤3.0 x ULN); Serum creatinine ≤2 x ULN or creatinine clearance of ≥45 mL/min.
✓. Willing to undergo either excised or large-needle lymph node or tissue biopsy, or provide formalin-fixed paraffin-embedded (FFPE) tumor tissue block or freshly cut unstained slides.
✓. Willing to complete all scheduled visits and assessments at the institution administering therapy.
Exclusion criteria
✕. Having KRAS (G12V or G12D or G12C) germline mutation.

Immune Response
Timeframe: Peripheral blood: baseline, weekly before Week 9, prior to each vaccination after Week 9 until last vaccination and 1 year after last vaccine. Tumor tissue: baseline, Week 3, and following timing will be performed according to subject's condition.
✕. Active central nervous system disease involvement (but allow patients with prior brain metastases treated at least 4 weeks prior to enrollment that are clinically stable and do not require intervention), or prior history of NCI CTCAE Grade ≥3 drug-related CNS toxicity.
✕. Prior organ allograft transplantations or allogeneic hematopoietic stem cell transplantation.
✕. Evidence of active uncontrolled viral, bacterial, or systemic fungal infection.
✕. Known positive test result for human immunodeficiency virus (HIV) or acquired immune deficiency syndrome (AIDS).
✕. Active infection of hepatitis B virus (HBV), or hepatitis C virus (HCV).
✕. Patients with history (within the last 5 years) or risk of autoimmune disease who have immunosuppressive medications or immunosuppressive doses of systemic corticosteroids (\>10 mg/day prednisone or equivalent) within 28 days prior to enrollment. However, patients who received a short course of corticosteroids (eg, premedication prior to antibody drug) will be eligible for study entry.
✕. Major trauma or major surgery within 4 weeks prior to enrollment.
