SNG100, a novel topical treatment for moderate atopic dermatitis, in patients aged 6 years or older: A randomised, double-blind, active-controlled trial.

Background: Atopic dermatitis (AD) is one of the most common inflammatory skin diseases. It is associated with significant itch and impaired quality of life. Systemic treatments are efficient but associated with side effects.

Subcutaneous Administration of Carbidopa Enhances Oral Levodopa Pharmacokinetics: A Series of Studies Conducted in Pigs, Mice, and Healthy Volunteers.

Objectives: Although commercially available levodopa (LD) formulations include carbidopa (CD) or benserazide for gastrointestinal L-aromatic amino acid decarboxylase inhibition, little is known how manipulating CD delivery affects the pharmacokinetics of LD. Our research systematically evaluated the peripheral and central pharmacokinetics of LD during continuous subcutaneous CD delivery.

Methods: We conducted pharmacokinetic experiments in pigs, mice, and humans to characterize effects of continuous subcutaneous CD delivery co-administered with LD as compared with oral LD/CD administration on LD pharmacokinetics.

Ninety-day Local Tolerability and Toxicity Study of ND0612, a Novel Formulation of Levodopa/Carbidopa, Administered by Subcutaneous Continuous Infusion in Minipigs.

A 90-day study in Göttingen minipigs was conducted to test the local tolerability and systemic toxicity of ND0612, a novel aqueous solution of carbidopa (CD)/levodopa (LD) intended for the treatment of Parkinson's disease by continuous subcutaneous administration using a discrete infusion pump. To evaluate tissue site reactions, we used a unique study design involving multiple infusion sites to evaluate the effect of dose per site (270/63, 360/45, and 360/84 mg LD/CD), volume of infusion per site (4.5 and 6 ml per site), formulation concentration (60/14 and 60/7.

Magnetic Resonance Imaging as a Noninvasive Method for Longitudinal Monitoring of Infusion Site Reactions Following Administration of a Novel Apomorphine Formulation.

Infusion site reactions are common following subcutaneous infusion of drugs. Such reactions can lead to discontinuation of the treatment. Therefore, assessment of such reactions is essential during preclinical safety studies, and magnetic resonance imaging (MRI) can assist in evaluation.

Heparanase is expressed in osteoblastic cells and stimulates bone formation and bone mass.

Heparan sulfate proteoglycans (HSPGs) are ubiquitous macromolecules. In bone, they are associated with cell surfaces and the extracellular matrix (ECM). The heparan sulfate (HS) chains of HSPGs bind a multitude of bioactive molecules, thereby controlling normal and pathologic processes.

Heparanase accelerates wound angiogenesis and wound healing in mouse and rat models.

Orchestration of the rapid formation and reorganization of new tissue observed in wound healing involves not only cells and polypeptides but also the extracellular matrix (ECM) microenvironment. The ability of heparan sulfate (HS) to interact with major components of the ECM suggests a key role for HS in maintaining the structural integrity of the ECM. Heparanase, an endoglycosidase-degrading HS in the ECM and cell surface, is involved in the enzymatic machinery that enables cellular invasion and release of HS-bound polypeptides residing in the ECM.

Activation, processing and trafficking of extracellular heparanase by primary human fibroblasts.

Heparanase is a heparan-sulfate-degrading endoglycosidase that has important roles in various biological processes, including angiogenesis, wound healing and metastatsis. Human heparanase is synthesized as a 65 kDa latent precursor, which is proteolytically processed into a highly active 50 kDa form. Extracellular heparanase is found in various tissues and is utilized by both normal cells and metastatic cancer cells to degrade heparan sulfate moieties in basement membranes and extracellular matrices.
