3 Clinical Trials for Various Conditions
The objective of this Phase 1 safety study is to provide access to the potential therapeutic benefit of EBOV convalescent plasma containing antibodies to EBOV. The risk of exposure to plasma from donors who may be infected with other transfusion-transmitted pathogens, not detectable by current licensed donor testing procedures, will be mitigated by using pathogen inactivation to minimize the risk of the TTI from these donors, who would otherwise be deferred and ineligible for blood donation.
Primary Objective: • To evaluate the safety and tolerability of cAd3-EBO-S and cAd3 Marburg vaccines when administered Intramuscular (IM) at a dose of 1 x 10\^11 particle units (PU) to healthy adults. Secondary Objectives: * To evaluate the antibody response to Monovalent Chimpanzee Adenoviral Vectored Filovirus Ebola-S (cAd3-EBO-S) and Monovalent Chimpanzee Adenoviral Vectored Filovirus (Marburg) (cAd3 Marburg) vaccines as assessed by antigen glycoprotein (GP) specific (enzyme-linked immunosorbent assay) ELISA * To collect sufficient post-vaccination plasma to support further development of filovirus assays
This study will examine the safety of an experimental medication called Poly-ICLC, developed for preventing or reducing the severity of infections from influenza and other viruses acquired through the nose, mouth and lungs. The study is divided into two parts, in which Poly-ICLC is tested at different dose levels. Healthy people between 18 and 70 years of age who have no chronic medical problems may be eligible for this study. Participants undergo the following procedures: Part I * Up to 7 days before Poly-ICLC administration: Medical history, physical examination and blood tests. * Day 1: Nasal wash and Poly-ICLC administration. A small amount of salt water is placed into the front of the nose and then suctioned out. Poly-ICLC is then squirted into each nostril, one after the other, at a dose of 0.25, 0.5 or 1 mg. A small number of subjects are given a placebo (a solution with no active ingredient.) Subjects are observed in the clinic for 30 minutes after treatment. * Day 2: Subjects receive a second nasal wash and repeat blood tests. They keep a diary card for 1 week, recording any drug side effects. * Day 5: Subjects have repeat blood tests and a review of their diary card. The keep a diary card for another 3 weeks. * Day 12: Subjects are contacted by phone to review their diary card. * Day 28: Subjects are contacted by phone to review their diary card. Part II * Up to 7 days before Poly-ICLC administration: Medical history, physical examination and blood tests. * Day 1: Nasal wash and Poly-ICLC administration. Same as above for Part I participants. * Day 3: Subjects receive a second dose of medication and are observed again for 30 minutes. * Day 4: Subjects receive a second nasal wash and repeat blood tests. They keep a diary card for 1 week, recording any drug side effects. * Day 7: Subjects have repeat blood tests and a review of their diary card. The keep a diary card for another 3 weeks. * Day 14: Subjects are contacted by phone to review their diary card. * Day 28: Subjects are contacted by phone to review their diary card.
