Lumasiran, an RNAi Therapeutic for Primary Hyperoxaluria Type 1.

Background: Primary hyperoxaluria type 1 (PH1) is a rare genetic disease caused by hepatic overproduction of oxalate that leads to kidney stones, nephrocalcinosis, kidney failure, and systemic oxalosis. Lumasiran, an investigational RNA interference (RNAi) therapeutic agent, reduces hepatic oxalate production by targeting glycolate oxidase.

Methods: In this double-blind, phase 3 trial, we randomly assigned (in a 2:1 ratio) patients with PH1 who were 6 years of age or older to receive subcutaneous lumasiran or placebo for 6 months (with doses given at baseline and at months 1, 2, 3, and 6).

Patisiran, an RNAi Therapeutic, for Hereditary Transthyretin Amyloidosis.

Background: Patisiran, an investigational RNA interference therapeutic agent, specifically inhibits hepatic synthesis of transthyretin.

Methods: In this phase 3 trial, we randomly assigned patients with hereditary transthyretin amyloidosis with polyneuropathy, in a 2:1 ratio, to receive intravenous patisiran (0.3 mg per kilogram of body weight) or placebo once every 3 weeks.

Potent Antiviral Activities of the Direct-Acting Antivirals ABT-493 and ABT-530 with Three-Day Monotherapy for Hepatitis C Virus Genotype 1 Infection.

ABT-493 is a hepatitis C virus (HCV) nonstructural (NS) protein 3/4A protease inhibitor, and ABT-530 is an HCV NS5A inhibitor. These direct-acting antivirals (DAAs) demonstrated potent antiviral activity against major HCV genotypes and high barriers to resistance in vitro. In this open-label dose-ranging trial, antiviral activity and safety were assessed during 3 days of monotherapy with ABT-493 or ABT-530 in treatment-naive adults with HCV genotype 1 infection, with or without compensated cirrhosis.

Safety, tolerability, and efficacy of GSK1322322 in the treatment of acute bacterial skin and skin structure infections.

GSK1322322 represents a new class of antibiotics that targets an essential bacterial enzyme required for protein maturation, peptide deformylase. This multicenter, randomized, phase IIa study compared the safety, tolerability, and efficacy of GSK1322322 at 1,500 mg twice daily (b.i.

Expression of antimicrobial peptides in the normal and involved skin of patients with infective cellulitis.

Background: Endogenous antimicrobial peptides participate in the innate defense of skin against a variety of pathogens. The systemic expression of these peptides in normal-appearing skin of patients with infective cellulitis is unknown.

Methods: Study patients were adults with infective cellulitis and signs of systemic inflammation.

Telavancin versus standard therapy for treatment of complicated skin and skin structure infections caused by gram-positive bacteria: FAST 2 study.

Telavancin is a bactericidal lipoglycopeptide with a multifunctional mechanism of action. We conducted a randomized, double blind, active-control phase II trial. Patients > or = 18 years of age with complicated skin and skin structure infections caused by suspected or confirmed gram-positive organisms were randomized to receive either telavancin at 10 mg/kg intravenously every 24 h (q24h) or standard therapy (antistaphylococcal penicillin at 2 g q6h or vancomycin at 1 g q12h).

Telavancin versus standard therapy for treatment of complicated skin and soft-tissue infections due to gram-positive bacteria.

Background: Telavancin, a novel lipoglycopeptide, exerts concentration-dependent, rapid bactericidal activity on account of its multiple mechanisms of action. Telavancin is highly active against gram-positive bacteria, including methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-intermediate, and vancomycin-resistant strains.

Methods: We conducted a randomized, double-blind, controlled, phase-2 clinical trial.
