OTO-201 for the Treatment of Acute Otitis Externa: Results from a Phase 3 Randomized Clinical Study.

Objectives: OTO-201 is a ciprofloxacin otic suspension previously approved by the US Food and Drug Administration to treat children with bilateral otitis media with effusion requiring tympanostomy tube placement. In this phase 3, double-blind, randomized, prospective, sham-controlled, multicenter study, a single dose of OTO-201 was administered to the external auditory canal in subjects with unilateral or bilateral acute otitis externa.

Methods: Two hundred sixty-two subjects, 3 to 83 years of age, were randomized, and 260 subjects were included in the intent-to-treat analysis population: OTO-201 (0.

Immunogenicity and safety of an investigational hepatitis B vaccine with a toll-like receptor 9 agonist adjuvant (HBsAg-1018) compared with a licensed hepatitis B vaccine in patients with chronic kidney disease.

Background: Hemodialysis patients are at increased risk of hepatitis B virus (HBV) infection and patients with chronic kidney disease (CKD) are commonly hyporesponsive to HBV vaccines. Current recommendations for CKD patients are to utilize 4 double-doses (2×20 mcg HBsAg) of a licensed hepatitis B vaccine (HBsAg-Eng).

Methods: An observer-blind, randomized, active-controlled, parallel group, multicenter trial was conducted among 521 patients 18-75 years of age with CKD, comparing 3 single doses of an investigational hepatitis B vaccine (20 mcg rHBsAg+3000 mcg 1018, a toll-like receptor 9 agonist) given at 0, 4, and 24 weeks to 4 double-doses of HBsAg-Eng (2×20 mcg rHBsAg+500 mcg alum) given at 0, 4, 8, and 24 weeks (total of 8 injections).

Immunogenicity and safety of an investigational hepatitis B vaccine with a Toll-like receptor 9 agonist adjuvant (HBsAg-1018) compared to a licensed hepatitis B vaccine in healthy adults 40-70 years of age.

Background: The currently licensed hepatitis B vaccines have limitations including hyporesponsiveness in older adults, poor compliance, and the extended time for most persons to develop seroprotection (e.g. >6months).

Demonstration of safety and enhanced seroprotection against hepatitis B with investigational HBsAg-1018 ISS vaccine compared to a licensed hepatitis B vaccine.

Adults 40 years of age and older have been shown to be hypo-responsive immunologically to the currently available hepatitis B virus (HBV) vaccines. Three intramuscular doses of a Toll-like receptor 9 agonist, 1018 immunostimulatory sequence (1018 ISS) adjuvant, combined with recombinant hepatitis B surface antigen (HBsAg) demonstrated faster, superior, and more durable seroprotection than three doses of a licensed comparator HBV vaccine (Engerix-B(®)). This investigational vaccine, HBsAg-1018 ISS, was well tolerated with a safety profile similar to the comparator vaccine.

Results of PREVENT III: a multicenter, randomized trial of edifoligide for the prevention of vein graft failure in lower extremity bypass surgery.

Objective: The PREVENT III study was a prospective, randomized, double-blinded, multicenter phase III trial of a novel molecular therapy (edifoligide; E2F decoy) for the prevention of vein graft failure in patients undergoing infrainguinal revascularization for critical limb ischemia (CLI).

Methods: From November 2001 through October 2003, 1404 patients with CLI were randomized to a single intraoperative ex vivo vein graft treatment with edifoligide or placebo. After surgery, patients underwent graft surveillance by duplex ultrasonography and were followed up for index graft and limb end points to 1 year.

Risk factors, medical therapies and perioperative events in limb salvage surgery: observations from the PREVENT III multicenter trial.

Objectives: Patients who require infrainguinal revascularization for critical limb ischemia (CLI) are at elevated risk for cardiovascular events. The PREVENT III study was a prospective, randomized, multicenter, phase 3 trial of edifoligide for the prevention of vein graft failure in patients with CLI. We examined the baseline characteristics, perioperative medical therapies, and 30-day incidence of major cardiovascular events in the PREVENT III cohort.

Adefovir dipivoxil therapy for lamivudine-resistant hepatitis B in pre- and post-liver transplantation patients.

Three-hundred and twenty-four patients were enrolled in an open-label, multicenter, international study in which pre- and post-liver transplantation (LT) patients with recurrent chronic hepatitis B (CHB) and evidence of lamivudine-resistant HBV were treated with adefovir dipivoxil 10 mg once daily. In the pre- and post-LT cohorts, 128 and 196 patients were treated for a median duration of 18.7 and 56.
