Safety and Efficacy of Neoantigen-Based Personalized Immunotherapy as Consolidation Therapy After Standard Adjuvant Treatment in Resectable Stage III Colorectal Cancer or Non-Small Cell Lung Cancer
China6 participantsStarted 2020-10-30
Plain-language summary
The primary objective of this study is to evaluate the safety, efficacy, and methodological feasibility of sequential administration of neoantigen-based personalized immunotherapy following completion of standard adjuvant therapy in patients with colorectal cancer or non-small cell lung cancer who have undergone radical resection.
Based on previous safety clinical trial results of personalized anti-tumor neoantigen injections, the 300 μg/peptide dose is well tolerated.
Therefore, this study will assess the safety and preliminary efficacy of personalized anti-tumor neoantigen injections at a dose of 300 μg/peptide as consolidation therapy after standard postoperative adjuvant treatment in patients with stage III resectable colorectal cancer or non-small cell lung cancer, aiming to provide novel personalized therapeutic strategies to improve disease-free survival (DFS) and overall survival (OS) in these patients.

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
1
Safety and Tolerability Parameters:Number of participants with treatment-related adverse events as assessed by CTCAE v5.0
. Received postoperative adjuvant therapy in accordance with standard guideline-recommended regimens, completed the full guideline-recommended treatment cycles, and no new lesions were detected on imaging examinations;
. Complete imaging records must be available within 1 week prior to initiation of personalized immunotherapy, including but not limited to whole-body PET-CT and brain MRI. If whole-body PET-CT is not feasible, chest CT, contrast-enhanced abdominal CT, or bone ECT is required;
Exclusion criteria
. Poor general condition unsuitable for surgery or postoperative adjuvant therapy;
. New lesions detected on imaging after completion of postoperative adjuvant therapy;
. Received immunotherapy or other investigational medicinal products prior to surgery;
. Presence of other malignancies, except for cured basal cell carcinoma, thyroid carcinoma, cervical dysplasia, etc., and those who have been disease-free for more than 5 years and are considered at low risk of recurrence by the investigator;
. No actionable neoantigens identified for personalized immunotherapy after analysis of sequencing data;
. Prior history of bone marrow transplantation or stem cell transplantation;
. Concomitant use of any other anti-tumor drugs, anti-tumor therapies in other clinical trials, immunosuppressive agents, or long-term systemic glucocorticoids;
. Received any other vaccination within 4 weeks before treatment; Infection with HIV, HCV, or HBV; severe asthma; autoimmune disease or immunodeficiency; or immunosuppressed status (excluding vitiligo, type 1 diabetes, autoimmune hypothyroidism requiring hormonal therapy, and psoriasis not requiring systemic treatment);
