Filter by:Monocentric open-label phase I/II trial aiming at evaluating, in adjuvant setting, safety (primary outcome), immunological and clinical efficacy (secondary outcomes) of a non replicating recombinant vaccinia virus expressing cancer/testis antigen (CTA) derived epitopes and CD80 and CD40 ligand (CD40L, CD154) costimulatory molecules in patients with CTA expressing tumors.
This study will test an experimental antiviral drug called SIGA-246 for use against the smallpox virus (variola). Although smallpox has been universally eradicated, it could possibly be brought back as a bioweapon. In the event of a smallpox attack, it would be best to have an antiviral medication in addition to the smallpox vaccine. SIGA-246 has shown to have activity against other viruses from the same family (orthopoxvirus) that smallpox belongs to. Healthy volunteers who are 18-50 years of age and are not pregnant or breastfeeding may be eligible for this study. Candidates are screened with a medical history and physical examination, blood and urine tests, and an electrocardiogram. Participants are randomly assigned to receive a one-time dose of SIGA-246 (either 500 mg, 1000 mg, or 2000 mg) or a placebo (sugar pill) taken by mouth. They report to the clinic in the morning for the following procedures: - Insertion of intravenous (IV) line in the forearm. - Blood and urine tests before taking the study drug. - Drug administration within 30 minutes of eating a light breakfast. - Blood sampling from the IV line at 30 minutes and at 1, 1.5, 2, 2.5, 3, 3.5, 4, 5 and 6, 10 and 12 hours after taking SIGA-246 to determine how the drug is absorbed, distributed, broken down and excreted. Samples are also collected by needle stick at 24 and 48 hours for the same tests. - Electrocardiogram at 2 hours and 24 hours after taking SIGA-246. - 24-hour urine collection after taking the SIGA-246. - Complete diary card at home for 7 days after taking the SIGA-246. - Follow-up visits at about 2 weeks and about 4 weeks after taking SIGA-246. - Checks for health changes or problems at every visit.
The purpose of this study is to follow responses to treatment with vaccinia immune globulin (VIG) for safety and clinical benefit [during HIV vaccine research]. VIG is purified from human blood and used to treat serious infections of the vaccinia (smallpox vaccine) virus or similar viruses. It is the only treatment available for those viruses. The only available supply of VIG has developed a discoloration over time and therefore is considered an investigational new drug by the FDA. This study will allow it to be used for intramuscular injection in a controlled setting for people who may need it [during HIV vaccine research].
