Influenza Clinical Trial
Official title:
A Phase II Study in Healthy Adult and Elderly Populations to Assess the Safety and Immunogenicity of an Unadjuvanted Sanofi Pasteur H1N1 Influenza Vaccine Administered at Two Dose Levels
The purpose of this study is to assess the safety and the body's immune response (body's defense against disease) to an experimental H1N1 influenza vaccine in healthy adult and elderly populations. The study will enroll up to 450 healthy adults ages 18 and older with no history of H1N1 infection or vaccination. Two hundred individuals will be 18-64 years old, and the other 200 will be greater than or equal to 65 years of age. Participants will be randomly assigned to 1 of 2 possible vaccine groups: group 1 will receive 15 mcg of H1N1 vaccine; group 2 will receive 30 mcg of H1N1 vaccine. Both groups will receive vaccine injections on days 0 and 21 in the arm muscle. Study procedures include: medical history, physical exam, maintaining a memory aid, and blood sample collection. Participants will be involved in study related procedures for approximately 7 months.

Inclusion Criteria: - Are males or non-pregnant females age 18 and older, inclusive. - Women of child-bearing potential (not surgically sterile via tubal ligation, bilateral oophorectomy or hysterectomy or who are not postmenopausal for greater than or equal to 1 year) must agree to practice adequate contraception that may include, but is not limited to, abstinence, monogamous relationship with vasectomized partner, barrier methods such as condoms, diaphragms, spermicides, intrauterine devices, and licensed hormonal methods during the study for at least 30 days following the last vaccination. - Are in good health, as determined by vital signs, medical history to ensure any existing medical diagnoses or conditions are stable and not considered clinically significant, and targeted physical examination based on medical history. A stable chronic medical condition is defined as no change in prescription medication, dose, or frequency of medication in the last 3 months and health outcomes of the specific disease are considered to be within acceptable limits in the last 6 months. Any change that is due to change of health care provider, insurance company etc, or that is done for financial reasons, as long as in the same class of medication will not be considered a violation of this inclusion criterion. Any change in prescription medication due to improvement of a disease outcome will not be considered a violation of this inclusion criterion. - Are able to understand and comply with planned study procedures. - Provide written informed consent prior to initiation of any study procedures. Exclusion Criteria: - Have a known allergy to eggs or other components of the vaccine (including gelatin, formaldehyde, octoxinol, thimerosal, and chicken protein). - Have a positive urine or serum pregnancy test within 24 hours prior to vaccination (if female of childbearing potential), or women who are breastfeeding. - Have immunosuppression as a result of an underlying illness or treatment, or use of anticancer chemotherapy or radiation therapy (cytotoxic) within the preceding 36 months. - Have an active neoplastic disease or a history of any hematologic malignancy. - Have long term use of glucocorticoids including oral, parenteral or high-dose inhaled steroids (>800 mcg/day of beclomethasone dipropionate or equivalent) within the preceding 6 months. (Nasal and topical steroids are allowed.) - Have a diagnosis of schizophrenia, bipolar disease, or other major psychiatric diagnosis. - Have been hospitalized for psychiatric illness, history of suicide attempt, or confinement for danger to self or others, within the past 10 years. - Are receiving psychiatric drugs (aripiprazole, clozapine, ziprasidone, haloperidol, molindone, loxapine, thioridazine, thiothixene, pimozide, fluphenazine, risperidone, mesoridazine, quetiapine, trifluoperazine, chlorprothixene, chlorpromazine, perphenazine, trifluopromazine, olanzapine, carbamazepine, divalproex sodium, lithium carbonate or lithium citrate). Subjects who are receiving a single antidepressant drug and are stable for at least 3 months prior to enrollment, without de-compensating symptoms will be allowed to be enrolled in the study. - Have a history of receiving immunoglobulin or other blood product within the 3 months prior to vaccination in this study. - Received an experimental agent (vaccine, drug, biologic, device, blood product, or medication) within 1 month prior to vaccination in this study or expect to receive an experimental agent during this study (prior to the Day 201 follow-up call - 180 days after the second vaccination). - Have received any live licensed vaccines within 4 weeks or inactivated licensed vaccines within 2 weeks prior to vaccination in this study or plan receipt of such vaccines within 21 days following the second vaccination. This is inclusive of seasonal influenza vaccines. - Have an acute or chronic medical condition that, in the opinion of the investigator, would render vaccination unsafe, or would interfere with the evaluation of responses. - Have a history of severe reactions following previous immunization with influenza virus vaccines. - Have an acute illness, including an oral temperature greater than 100.4 degrees Fahrenheit, within 3 days prior to vaccination. - Have any condition that would, in the opinion of the site investigator, place them at an unacceptable risk of injury or render them unable to meet the requirements of the protocol. - Participated in a novel influenza H1N1 2009 vaccine study in the past two years or have a history of novel influenza H1N1 2009 infection prior to enrollment. - Have known active human immunodeficiency virus (HIV), Hepatitis B or Hepatitis C infection. - Have a history of alcohol or drug abuse in the last 5 years. - Plan to travel outside of North America in the time between the first vaccination and 42 days following the first vaccination. - Have a history of Guillain-Barré Syndrome. - Have any condition that the investigator believes may interfere with successful completion of the study. |
