Phase I Dose Escalation SARS-CoV Recombinant S Protein, With and Without Adjuvant, Vaccine Study

Withdrawn before enrolling · Phase 1 · Has a placebo group

Conditions studied: SARS

In brief

This is a multi-center, randomized, double-blinded, placebo-controlled, outpatient study. Recombinant deltaTM S Protein Severe Acute Respiratory Syndrome (SARS) Vaccine With and Without Aluminum Hydroxide Adjuvant (Provided through contract N01-AI-30023, manufactured by Protein Sciences Corporation), two doses, administered at 28 day interval. 1. S Protein Severe Acute Respiratory Syndrome (SARS) Vaccine without adjuvant: 5.0, 15.0 and 45.0 mcg per 0.5 ml dose. 2. S Protein SARS Adjuvanted Vaccine: 5.0, 15.0 and 45.0 mcg per 0.5 ml dose. PLACEBO: diluents/placebo without vaccine (Phosphate Buffer Saline (PBS) with lower phosphate concentration). Approximately 84 healthy male and nonpregnant female subjects 18 to 40 years of age will be enrolled.

You may qualify if…

Males or nonpregnant females between the ages of 18 and 40 years, inclusive.
Women of childbearing potential (not surgically sterile via tubal ligation, bilateral oophorectomy or hysterectomy or who have not been postmenopausal for >/=1 year) must agree to practice adequate contraception for the 30-day period before vaccination through 90 days after the second vaccination. Acceptable birth control methods for the purposes of this study may include, but are not limited to, abstinence, monogamous relationship with vasectomized partner, barrier methods such as condoms, diaphragms, spermicides, and intrauterine devices, and licensed hormonal methods.
In good health, as judged by the investigator and determined by vital signs [temperature < 38 degrees C, heart rate </= 100 bpm and > 50 bpm, systolic blood pressure </= 140 mmHg and > 89 mmHg, diastolic blood pressure </= 90 mmHg and >/= 60 mm Hg, respiratory rate >/= 12 breath per minute and < 17 breaths per minutes (see toxicity table in Section 9.1.2)], medical history and a targeted physical examination, as indicated, based on medical history.
Screening laboratory values must be within normal limits. These include blood hemoglobin, white blood cell (WBC) count, eosinophils, platelets, absolute eosinophil, neutrophil, and lymphocyte cell counts, creatinine, aspartate aminotransferase (AST), alanine transaminase (ALT), bilirubin (total), glucose (random), and urinalysis (proteinuria and hematuria). See toxicity table in Section 9.1.3.2. Note: creatinine values lower than the normal are acceptable.
Able to understand and comply with planned study procedures.
Willing to be available for all study-required procedures, visits and calls for the duration of the study.
Provide written informed consent before initiation of any study procedures and be available for all study visits.
Negative for IgG antibodies to S protein of Severe Acute Respiratory Syndrome coronavirus (SARS-CoV) measured by ELISA.
Negative for antibodies to Human Immunodeficiency Virus (HIV) and hepatitis C virus and for hepatitis B surface antigen.
Negative for IgG antibodies to S protein of Severe Acute Respiratory Syndrome coronavirus (SARS-CoV) measured by ELISA.
Negative for antibodies to Human Immunodeficiency Virus (HIV) and hepatitis C virus and for hepatitis B surface antigen.

You may not qualify if…

A known allergy to components of the vaccine.
A positive serum or urine pregnancy test within 24 hr prior to vaccination (if female of childbearing potential as defined in Inclusion Criterion 2), women who are planning to become pregnant from 30 days prior to entering the study until 90 days after the final study vaccination, or women who are breastfeeding.
Immunosuppression as result of underlying illness or treatment or use of anticancer chemotherapy or radiation therapy (cytotoxic) within the preceding 36 months.
An active neoplastic disease (excluding nonmelanoma skin cancer or prostate cancer that is stable in the absence of therapy) or a history of any hematologic malignancy. Nonactive neoplastic disease is defined as no neoplastic disease or treatment for neoplastic disease within the past 5 years.
A history of autoimmune disease (systemic lupus, rheumatoid arthritis, scleroderma, polyarteritis, thyroiditis, etc).
Used an immunosuppressive or immunomodulatory drug such as >0.5 mg/kg/day or >/=20 mg total dose/day of prednisone orally or >800 mcg of inhaled beclomethasone for 2 or more consecutive weeks within 6 months prior to the 1st vaccination. (Nasal and topical steroids are allowed.)
A known human immunodeficiency virus (HIV) infection, or active hepatitis B, or hepatitis C virus infection.
A diagnosis of schizophrenia, bipolar disease, or other major psychiatric diagnosis in the past 3 years.
Hospitalized for psychiatric illness, history of suicide attempt, or confinement for danger to self or others in the past 3 years.
Receiving psychiatric drugs listed below*. Subjects who are receiving a single antidepressant drug and are stable for at least 3 months prior to enrollment, without decompensating symptoms will be allowed to be enrolled in the study.

A history of receiving immunoglobulin or other blood product within the previous 3 months before vaccination.
Received or plan to receive any live licensed vaccines within 4 weeks or inactivated licensed vaccines within 2 weeks of each vaccination,
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 or is not generally seen in healthy, normal subjects. (This includes, but is not limited to, known cardiac disease, pulmonary disease, liver disease, renal disease, unstable or progressive neurological disorders, diabetes mellitus, and transplant recipients.)
A history of severe reactions following immunization with vaccines.
Received an experimental agent (vaccine, drug, biologic, device, blood product, or medication) within 1 month before vaccination in this study or expect to receive an experimental agent during the 24-month study period.
Any condition that would, in the opinion of the investigator, place them at an unacceptable risk of injury, render them unable to meet the requirements of the protocol, or that may interfere with successful completion of the study.
A history of alcohol or drug abuse during the previous 1 year; for example, daily excessive alcohol use or frequent binge drinking as determined by the investigator, or chronic marijuana abuse or any other illicit drug use.
