About this trial

This is an interventional treatment trial for Carcinoma, Non-Small Cell Lung focused on measuring Neoantigen, Dentritic cell vaccine, Immunotherapy, Refractory lung cancer

Eligibility Criteria

18 Years - 70 Years (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Age ≥18 years ≤ 70 years at the time of informed consent
  • Signed informed consent to be provided
  • pathologically confirmed lung cancer
  • failed in previous standard chemotherapy and targeted therapy
  • Life expectancy not less than 90 days
  • Karnofsky performance status 0-1
  • adequate organ functions

Exclusion Criteria:

  • Actively infectious condition including hepatitis
  • Women of child-bearing potential who are pregnant or breastfeeding because of the potentially dangerous effects of the treatment on the fetus or infant.
  • Any form of primary immunodeficiency (such as Severe Combined Immunodeficiency Disease).
  • Concurrent opportunistic infections (The experimental treatment being evaluated in this protocol depends on an intact immune system. Patients who have decreased immune competence may be less responsive to the experimental treatment and more susceptible to its toxicities).
  • Active systemic infections, coagulation disorders or any other active major medical illnesses.
  • Patients who are receiving any other investigational agents.

Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

Vaccinated group

Arm Description

Neoantigen loaded-DC vaccination will be performed with 6 doses in total, once per week, adjacent lymph-node injection.

Outcomes

Primary Outcome Measures

Incidence of Treatment-Emergent Adverse Events [Safety]
Safety of personalized neoantigen vaccine will be measured by the number of subjects experiencing each type of adverse event. Adverse events will be graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events v4.0.
Immunogenicity of neoantigen-primed DC Vaccines
Immunogenicity of the DC vaccine will be measured to detect changes of neoantigen-specific T cells by flow cytometry.

Secondary Outcome Measures

Objective Response Rate
The objective response rate is equal to the proportion of participants achieving a best overall response of partial response or complete response (PR + CR). Percentage of Participants Achieving a Stable Disease (SD) or a confirmed CR or PR (Disease Control Rate) Participants achieved disease control if they had a best overall response of CR, PR or SD.
Overall Survival (OS)
OS was defined as the time in months from the date of randomization to the date of death from any cause. For participants not known to have died as of the cut-off date, OS was censored at the last known date alive.
Progression-free Survival (PFS)
PFS:duration of time from start of treatment to time of progression or death, whichever occurs first.

5. Study Description

Brief Summary
Various of immunotherapies are now widely applied in the treatment of lung cancer. Neoantigens arising from the mutations of the tumor genome expressed specifically on the tumor cell instead of normal cells, suggesting that vaccines targeting neoantigens should generate a highly tumor-specific response with minimal off-target effects. Neoantigens are highly suitable for the development of cancer vaccines. The study aims to evaluate the safety and efficacy of neoantigen-loaded dendritic cell (DC) vaccines for refractory lung cancer.
Detailed Description
Cancer genome research has exploded benefits from the application of modern high-throughput genome sequencing in the past few years. Since usually there are no common antigens expressed on the surfaces of different kinds of tumors, neoantigens which expressed specifically in the individual tumor are chosen to establish tumor-specific vaccines. 30 patients with refractory lung cancer would be enrolled and undergo tumor resection if all requirements are met. The whole-exome sequencing and the bioinformatic analysis of the resected specimens would be performed to identify the neoantigens. Then, candidate neoantigens would be synthesized to pulse the matured DC cells. Neoantigen-primed DC vaccines are provided to the corresponding patients. Each patient would be vaccinated 6 times in total, one shot per week. Patients enrolled would undergo the schemed follow-up, one time per three months. The side effects, overall survival, and progress-free survival would be recorded. At the end of the research, the safety and efficacy of neoantigen DC vaccines for refractory lung cancer would be evaluated.
