MRNA Neoantigen Vaccine in Non-Small Cell Lung Cancer

Официальное название

An Exploratory Study of the Personalized MRNA Neoantigen Vaccine in Combination with Adebrelimab As Adjuvant Treatment for Patients with Resected Non-small Cell Lung Cancer

Обзор

Brief Summary: This study is an open, prospective, exploratory clinical trial designed to evaluate the safety,ability, immunogenicity, and preliminary efficacy of a personalized neoantigen mRNA vaccine in combination with adebelimab as adjuvant treatment for patients with non-small cell lung cancer (NSCLC). The primary objectives of this study are to answer the following key questions: 1. The incidence of dose-limiting toxicities (DLTs) during the designated observation period. 2. The incidence and severity of adverse events (AEs) and serious adverse events (SAEs). 3. The determination of the maximum tolerated dose (MTD) or maximum administered dose (MAD).

Вмешательства

• Препарат mRNA Neoantigen Vaccine
  mRNA Neoantigen Vaccine
• Препарат Adebrelimab
  Adebrelimab is a programmed death-ligand 1 antibody.

Первичные конечные точки

• safety and tolerability [Срок оценки: From the start of study treatments until 30 days after last dose of study treatments.]
• MTD or MAD [Срок оценки: From the start of study treatments until the end of the safety run-in phase, about 4 months.]

Вторичные конечные точки (2)

• immunogenicity [Срок оценки: From the sugery til the end of study treatment，about 18 months.]
• Preliminary efficacy [Срок оценки: 3years]

• Any person who is not suitable for immunotherapy as assessed by the investigator
• Presence of autoimmune diseases, except for hypothyroidism due to autoimmune thyroiditis that only requires hormone replacement therapy
• Evidence of active tuberculosis infection within 1 year prior to initiation of study treatment, regardless of treatment
• Subjects with a known history of interstitial pneumonia or a high suspicion of interstitial pneumonia, or evidence of active interstitial pneumonia on chest CT during the pre-screening period; Known history of idiopathic pulmonary fibrosis, history of organizing pneumonia (such as bronchiolitis obliterans or cryptogenic organizing pneumonia); and subjects who may interfere with the detection or management of suspected drug-related pulmonary toxicity
• Severe infection (such as intravenous infusion of antibiotics, antifungal or antiviral drugs required according to clinical diagnosis and treatment standards) within 28 days before starting study treatment, or active infection that has received therapeutic intravenous or oral antibiotics within 14 days before starting study treatment
• Known allergy to the study drug or any of its excipients, or history of severe allergic reactions to other vaccines
• Subject has a history of other malignancies within the past 5 years or at the same time, excluding cured carcinoma in situ of the cervix, basal cell carcinoma of the skin or squamous cell carcinoma of the skin, localized prostate cancer after radical resection, ductal carcinoma in situ after radical resection (hormonal therapy for non-metastatic prostate cancer or breast cancer is allowed), and papillary thyroid carcinoma

• In the opinion of the investigator, the subject has a history of other serious systemic diseases, or other reasons are not suitable for participating in this clinical study (such as any other disease that may affect the subject's compliance with the study treatment, interfere with the interpretation of the study results, or expose the subject to safety risks, or the tumor tissue sequencing data analysis results show that there are not enough neoantigens available for vaccine preparation, or the vaccine preparation fails); Other circumstances judged by the investigator that may affect the conduct of clinical research and the judgment of research results
