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.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring

Incidence of treatment related adverse events (AEs)
Timeframe: 2 years

Clinical Response
Timeframe: 2 years
3
Disease Control
Timeframe: 2 years
4
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.
. 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.
. 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.
