Scientific title	Mature Autologous Dendritic Cell Vaccines in Advanced Non-Small Cell Lung Cancer
Study objectives	To evaluate the feasibility, safety and immunologic responses in use in mature, antigen-pulsed autologous dendritic cell (DC) vaccine in non-small cell lung cancer (NSCLC) patients.
Ethics approval(s)	Human Research Ethics Committee from State University of Campinas, 27th September 2005 (ref: 452/2005)
Health condition(s) or problem(s) studied	Non-Small Lung Cancer
Intervention	1. All selected patients received conventional treatment (chemotherapy with or without radiotherapy). 2. The chemotherapy protocols included paclitaxel 175 mg/m2 and cisplatinum 70 mg/m2 on day 1. These cycles were then repeated four times every 21 days. 3. After the fourth chemotherapy cycle, the patients were submitted to 3.1. computed tomography (CT) scan of thorax, abdomen and brain to evaluate the tumor response 3.2. Leukapheresis 4. Immunization Protocol: a prime vaccine and a single boost were given fifteen days apart. For each dose of vaccine, two aliquots were prepared in separate syringes with saline solution. First, a dose was subcutaneously administered in the arm and after 1 hour the second dose was given intravenously in the other arm. After the second dose, the patient remained under observation for 1 hour for evaluation of immediate unexpected adverse events.
Intervention type	Drug
Phase	Not Applicable
Drug / device / biological / vaccine name(s)	Dendritic Cell Vaccines
Primary outcome measure(s)	1. Measurable immunologic response: The cellular composition of the immune system, before and after vaccination with the dendritic cells, was assessed from peripheral blood samples using flow cytometry. The day of immunisation was considered as Day 0. The peripheral blood samples were collected one week before vaccination (Day -7), two weeks after the first dose of vaccine (Day 14), two weeks after the second dose of vaccine (Day 28) and one month (Day 43) after the end of the vaccination protocol. The lymphoproliferation test was used to assess the ability of dendritic cells to stimulate specific lymphocytes in vivo. 2. Safety was evaluated by the clinical and laboratorial evolution according Cancer Therapy Evaluation Program (CTEP) and Common Terminology Criteria for Adverse Events (CTCAEv3)
Key secondary outcome measure(s)	Therapeutic effects of immunotherapy: tumor response to the vaccine was evaluated by RECISTs criteria
Completion date	30/04/2009
