The study is designed for patients whose tumors have specific mutations identifiable through genomic sequencing. These mutations, known as neoantigens, are unique to each patient's cancer and serve as the target for the personalized vaccine.\n\nEligible patients will undergo genomic analysis, including whole exome sequencing and RNA sequencing, to identify these neoantigens. A custom peptide vaccine will then be produced and formulated to target these neoantigens. The trial consists of a preparation phase, a treatment phase with priming and booster vaccinations, and a follow-up/maintenance period of one year. The study will assess immune responses, clinical efficacy, and potential toxicities. By leveraging the immune system's ability to recognize and attack cancer cells, this vaccine aims to provide a new treatment option for patients with limited alternatives.", "detailedDescription"=>"This Phase Ib/II, open-label, single-center study investigates the safety, immunogenicity, and preliminary efficacy of a personalized neoantigen peptide vaccine in patients with advanced cancer or high risk of recurrence. The trial aims to enroll 15-35 eligible patients and is divided into three phases: preparation, treatment, and follow-up.\n\nPreparation Phase: Patients undergo genomic analysis using whole exome sequencing and RNA sequencing to identify specific neoantigens from their tumor tissues. Based on these findings, a personalized neoantigen peptide vaccine is produced and formulated. Poly-ICLC, an immune adjuvant, is administered intramuscularly twice weekly for four weeks prior to the first vaccine dose to enhance immune readiness.\n\nTreatment Phase: The neoantigen peptide vaccine is administered alongside Poly-ICLC on days 1, 4, 8, 15, and 22. A checkpoint inhibitor (e.g., anti-PD-1 or anti-PD-L1) will be introduced once neoantigen-specific T cell responses are detected, to prevent immune exhaustion and sustain the immune response. Booster injections of the neoantigen vaccine are scheduled for weeks 12 and 20. Immune responses and adverse events will be closely monitored throughout this phase.\n\nFollow-up Phase: During the follow-up phase, checkpoint inhibitors (administered per standard regimen) and Poly-ICLC (administered twice monthly) will be continued to maintain immune activity and ensure a lasting anti-tumor response. Safety, immune activity, and clinical outcomes will be closely monitored over a one-year period.\n\nThe primary endpoints include safety and immunogenicity, measured by adverse event monitoring and T-cell activation assays. Secondary endpoints will assess clinical efficacy, including tumor response rates, progression-free survival, and overall survival. Exploratory endpoints will involve biomarker analysis and immune profiling to correlate clinical outcomes with specific immune responses.\n\nThis study aims to validate the hypothesis that personalized neoantigen peptide vaccines, in combination with immune adjuvants and checkpoint inhibitors, can elicit strong immune responses and improve clinical outcomes in patients with advanced or high-risk recurrent cancers, especially where standard therapies have failed."}, "eligibilityModule"=>{"sex"=>"ALL", "stdAges"=>["ADULT", "OLDER_ADULT"], "minimumAge"=>"18 years", "healthyVolunteers"=>false, "eligibilityCriteria"=>"Inclusion Criteria:\n\nCancer patients will be selected from those receiving treatment at the Cancer Center, Vejthani Hospital.
