Randomized Controlled Trial Multicenter Study
CYT003, a TLR9 agonist, in persistent allergic asthma - a randomized placebo-controlled Phase 2b study.
New treatment options are required for patients with asthma not sufficiently controlled with inhaled therapies. In a Phase 2a trial, CYT003, a Toll-like receptor-9 agonist immunomodulator, improved asthma control during inhaled glucocorticosteroid reduction in patients with allergic asthma. This double-blind Phase 2b study assessed the efficacy and safety of CYT003 in patients with persistent moderate-to-severe allergic asthma not sufficiently controlled on standard inhaled glucocorticosteroid therapy with/without long-acting beta-agonists (LABAs). ⋯ Toll-like receptor-9 agonism with CYT003 showed no additional benefit in patients with insufficiently controlled moderate-to-severe allergic asthma receiving standard inhaled glucocorticosteroid therapy with or without LABAs.

Randomized Controlled Trial Multicenter Study
Antisense Inhibition of Apolipoprotein C-III in Patients with Hypertriglyceridemia.
Apolipoprotein C-III (APOC3) is a key regulator of plasma triglyceride levels. Elevated triglyceride levels are associated with a risk of adverse cardiovascular events and pancreatitis. ISIS 304801 is a second-generation antisense inhibitor of APOC3 synthesis. ⋯ We found that treatment with ISIS 304801 was associated with significant lowering of triglyceride levels, among patients with a broad range of baseline levels, through selective antisense inhibition of APOC3 synthesis.

Randomized Controlled Trial Multicenter StudyResults of a proof of concept, double-blind, randomized trial of a second generation antisense oligonucleotide targeting high-sensitivity C-reactive protein (hs-CRP) in rheumatoid arthritis.
This randomized, double-blind, phase II study evaluated the pharmacodynamics, safety and tolerability of ISIS 329993 (ISIS-CRPRx), an antisense oligonucleotide, in patients with active rheumatoid arthritis (RA). ⋯ In this study, ISIS-CRPRx selectively reduced hs-CRP in a dose-dependent manner, and was well-tolerated in patients with RA. Its utility as a therapy in RA remains unclear.

Randomized Controlled Trial Multicenter Study
Mongersen, an oral SMAD7 antisense oligonucleotide, and Crohn's disease.
Crohn's disease-related inflammation is characterized by reduced activity of the immunosuppressive cytokine transforming growth factor β1 (TGF-β1) due to high levels of SMAD7, an inhibitor of TGF-β1 signaling. Preclinical studies and a phase 1 study have shown that an oral SMAD7 antisense oligonucleotide, mongersen, targets ileal and colonic SMAD7. ⋯ We found that study participants with Crohn's disease who received mongersen had significantly higher rates of remission and clinical response than those who received placebo.

Randomized Controlled Trial Multicenter Study Comparative Study
Factor XI antisense oligonucleotide for prevention of venous thrombosis.
Experimental data indicate that reducing factor XI levels attenuates thrombosis without causing bleeding, but the role of factor XI in the prevention of postoperative venous thrombosis in humans is unknown. FXI-ASO (ISIS 416858) is a second-generation antisense oligonucleotide that specifically reduces factor XI levels. We compared the efficacy and safety of FXI-ASO with those of enoxaparin in patients undergoing total knee arthroplasty. ⋯ This study showed that factor XI contributes to postoperative venous thromboembolism; reducing factor XI levels in patients undergoing elective primary unilateral total knee arthroplasty was an effective method for its prevention and appeared to be safe with respect to the risk of bleeding.
