Systemic Bioavailability of Sublingual Atropine Ophthalmic Solution: a Phase I Study in Healthy Volunteers with Implications for Use as a Contingency Medical Countermeasure.

Introduction: Atropine sulfate is an FDA-approved medical countermeasure (MCM) for the treatment of organophosphorus nerve agent and organophosphate pesticide toxicity. Sufficient MCM supplies must be available in an incident involving a mass human exposure either from an accidental chemical release or a terrorist attack.

Methods: We performed a randomized, 3-sequence, 3-period phase I crossover study to assess the bioavailability and pharmacokinetics (PK) of a single dose (0.

Adjuvanted recombinant hemagglutinin H7 vaccine to highly pathogenic influenza A(H7N9) elicits high and sustained antibody responses in healthy adults.

An unprecedented number of human infections with avian influenza A(H7N9) in the fifth epidemic wave during the winter of 2016-2017 in China and their antigenic divergence from the viruses that emerged in 2013 prompted development of updated vaccines for pandemic preparedness. We report on the findings of a clinical study in healthy adults designed to evaluate the safety and immunogenicity of three dose levels of recombinant influenza vaccine derived from highly pathogenic A/Guangdong/17SF003/2016 (H7N9) virus adjuvanted with AS03 or MF59 oil-in water emulsions. Most of the six study groups meet the FDA CBER-specified vaccine licensure criterion of 70% seroprotection rate (SPR) for hemagglutination inhibition antibodies to the homologous virus.

Evaluation of BioThrax® and AV7909 anthrax vaccines in adults 66 years of age or older.

Background: Multiple Anthrax vaccines are licensed or in development for post-exposure prophylaxis in individuals 18 to 65 years of age. No information exists on anthrax vaccines in populations over the age of 65. It is critical that we assess the capacity of anthrax vaccines to generate a protective immune response in older individuals.

Efficacy and safety of oral solithromycin versus oral moxifloxacin for treatment of community-acquired bacterial pneumonia: a global, double-blind, multicentre, randomised, active-controlled, non-inferiority trial (SOLITAIRE-ORAL).

Background: Community-acquired bacterial pneumonia (CABP) is a leading cause of morbidity and mortality, and treatment recommendations, each with specific limitations, vary globally. We aimed to compare the efficacy and safety of solithromycin, a novel macrolide, with moxifloxacin for treatment of CABP.

Methods: We did this global, double-blind, double-dummy, randomised, active-controlled, non-inferiority trial at 114 centres in North America, Latin America, Europe, and South Africa.

Early phase evaluation of SQ109 alone and in combination with rifampicin in pulmonary TB patients.

Objectives: SQ109, an asymmetrical diamine, is a novel anti-TB drug candidate. This first study in patients was done to determine safety, tolerability, pharmacokinetics and bacteriological effect of different doses of SQ109 alone and in combination with rifampicin when administered over 14 days.

Patients And Methods: Smear-positive pulmonary TB patients were randomized into six groups of 15 to receive once-daily oral treatment with 75, 150 or 300 mg of SQ109, rifampicin (10 mg/kg body weight), rifampicin plus 150 mg of SQ109, or rifampicin plus 300 mg of SQ109 for 14 days.

The immunogenicity and safety of a nicotine vaccine in smokers and nonsmokers: results of a randomized, placebo-controlled phase 1/2 trial.

This randomized, placebo-controlled phase 1/2 trial evaluated the safety and immunogenicity of four doses of a nicotine vaccine in smokers and nonsmokers. Subjects were 21 smokers and 9 nonsmokers in good physical and mental health. They were aged 24-60 years, were recruited from the general public using newspaper advertisements, and were evaluated at University Hospital Maastricht.

Protective antibody levels and dose requirements for IV 5% Nabi Hepatitis B immune globulin combined with lamivudine in liver transplantation for hepatitis B-induced end stage liver disease.

Lamivudine combined with Hepatitis B immune globulin (HBIg) prevents post liver transplant (LT) HBV recurrence. The study was designed to assess the impact of lamivudine on hepatitis B antibody (anti-HBs) and dosage requirements of intravenous 5% HBIg (Nabi-HB) in the first 36 weeks post LT. Adults undergoing LT for chronic HBV received lamivudine prior to or at LT, and IV HBIg 20,000 IU on day of LT, 10,000 on days 1-7, weeks 4 and 8, and 5,000 every 4 weeks thereafter.

Safety and immunogenicity of a nicotine conjugate vaccine in current smokers.

Immunotherapy is a novel potential treatment for nicotine addiction. The aim of this study was to assess the safety and immunogenicity of a nicotine conjugate vaccine, NicVAX, and its effects on smoking behavior. Smokers (N = 68) were recruited for a noncessation treatment study and assigned to 1 of 3 doses of the nicotine vaccine (50, 100, or 200 microg) or placebo.

Safety and immunogenicity of a booster dose of Staphylococcus aureus types 5 and 8 capsular polysaccharide conjugate vaccine (StaphVAX) in hemodialysis patients.

StaphVAX, an unadjuvanted, bivalent vaccine composed of Staphylococcus aureus (S. aureus) capsular polysaccharides (CPS) types 5 and 8 bound to the mutant non-toxic recombinant Pseudomonas aeruginosa exotoxin A (rEPA) conferred approximately 60% protection for 10 months against bacteremia caused by this pathogen in hemodialysis patients. A protective level of 80 microg/ml was estimated based upon geometric mean (GM) antibody levels at the end of the efficacy period.

Staphylococcus aureus types 5 and 8 capsular polysaccharide-protein conjugate vaccines.

Background: Staphylococcus aureus, the first or second most common pathogen isolated from patients, is capsulated; there are at least 12 capsular types, and types 5 and 8 comprise approximately 85% of blood. Types 5 and 8, composed of a trisaccharide repeat unit including a mannose uronic acid and 2 fucoses, are non-immunogenic. As protein conjugates, they induce opsonophagocytic antibodies that confer type-specific active and passive protection in mice.

Development of StaphVAX, a polysaccharide conjugate vaccine against S. aureus infection: from the lab bench to phase III clinical trials.

Staphylococcus aureus is the most common nosocomial pathogen and is responsible for approximately one-third of hospital-acquired bacteremias. The emergence of strains with multidrug resistance, including resistance to vancomycin, the antibiotic of last resort, presents the medical community with a major public health problem. Alternative therapies, including immunotherapy, have been in development for several decades.

Use of a Staphylococcus aureus conjugate vaccine in patients receiving hemodialysis.

Background: In patients with decreased resistance to infection, Staphylococcus aureus is a major cause of bacteremia and its complications. The capsular polysaccharides are essential for the pathogenesis of and immunity to S. aureus infection and are targets for vaccines.
