Background: To assess the efficacy and safety of a combination therapy involving fimasartan, amlodipine, and rosuvastatin in patients with essential hypertension and dyslipidemia who fail to respond to fimasartan monotherapy.
Methods: This phase III, randomized, double-blind, multicenter study was conducted in adults aged 19-70 years. Patients who voluntarily consented were screened for eligibility to enroll in the study.
Background: Fimasartan (Kanarb; Boryung Pharmaceutical Co., Ltd., Seoul, Republic of Korea) is a non-protein angiotensin II receptor blocker that selectively blocks the AT1 receptor.

The multi-center, prospective, open-label and non-interventional study. A total of 3,945 patients (3,729 patients for safety assessment and 3,473 patients for efficacy assessment) were screened in patients with essential hypertension in 89 study centers from 9 September 2010 through 8 September 2016.

Here, we report an initial evaluation of the preclinical safety of AcHERV-HPV16L1 vaccine. In an acute toxicity study, a single administration of AcHERV-HPV16L1 DNA vaccine given intramuscularly (i.

Here, we report tetraiodothyroacetic acid (tetrac) as a promising new targeting moiety for delivery of anticancer drugs to tumor tissues. Tetrac, an antagonist that blocks the binding of thyroid hormone to integrin αvβ3, was covalently linked to the activated end of pegylated lipid and used to formulate tetrac-tagged pegylated liposomes (TPL).

This would amplify in situ homing signals and thus drug delivery by apoptosis-targeted drugs. To examine this possibility, we prepared apoptosis-targeted liposomes containing doxorubicin by labeling them with the CQRPPR peptide (ApoPep-1) that recognizes apoptotic cells by binding to histone H1.

Cationic mPEI was electrostatically complexed to a plasmid encoding the human papillomavirus (HPV) type 16L1 protein (pHPV16L1), and further complexed to a maltose binding protein (MBP)-fused human papillomavirus type 16L1 fusion protein (HPV16L1-MBP). The HPV16L1-MBP/mPEI/pHPV16L1 complexes were characterized by gel-retardation properties, zeta potentials and sizes.

Here we have screened a phage-displayed peptide library to identify peptides that selectively bind to lung tumor cells. Evaluation of individual phage clones after screening revealed that a phage clone displaying the CSNIDARAC peptide bound to H460 lung tumor cells at higher extent than other phage clones.

Among various oligolysine-based lipid derivatives differing in lysine residue number and lipid moiety, trilysinoyl oleylamide (TLO)-based liposomes (TLOL) showed the highest delivery efficiency combined with minimal cytotoxicity. Delivery of siRNA using TLOL silenced target genes both in vitro and in vivo.

In aqueous medium, the tocopherol oligochitosan conjugates self-assembled to single layered oligomersomes. The sizes of α-tocopherol-oligochitosan-based oligomersomes (TCOsomes) could be controlled by chain lengths of oligochitosans.

We aimed to develop optimized liposomes for mitoxantrone (MTO) administration that provide high encapsulation efficiency and increase the therapeutic index. Cationic MTO was loaded onto anionic liposomes by electrostatic surface complexation.

Here, we described the synthesis of a new cationic lipid, N,N''-dioleylglutamide (DG), and evaluated DG-based liposomes as an siRNA delivery system. DG, an amino acid derivative, was synthesized by peptide bond linkage of oleylamine to each carboxylic acid group of glutamic acid.
