This thesis project covers the design, development and in vivo evaluation of a novel self-assembled injectable biodegradable drug delivery system (DDS), composed of in situ hydrogel combined with nanocapsules for lipophilic anti-inflammatory drugs, aiming prolonged intra-articular (IA) residence time and controlled drug release. The moderate initial viscosity allows good syringeability, while rheological properties of the assembled DDS enable resistance to high deformations, displaying the hydrogel suitable for IA application. In this regard, to validate the new delivery system, dexamethasone was used as a model drug. Besides, a novel and potential lead compound for immunotherapeutic anti-rheumatic drug candidate – galectin-3 antagonist was synthesized, characterized and evaluated in this study. The preliminary in vivo results demonstrated remarkable suppression of acute joint inflammation by galectin-3 inhibitor encapsulated within hydrogel and administrated IA at microgram scale doses compared to non-treated control. Overall, the work presented here portrays the DDS with encapsulated synthetic galectin-3 inhibitor as a capable in situ nanotechnology-based platform for arthropathies treatment, intended to contribute to efficient joints therapies.

abstract = {Abstract: Intra-articular (IA) administration of drugs is an appealing route for the effective treatment of large-joint diseases. However, a key limitation of this route is the premature elimination of the injected drugs from the synovial cavity. The objective of this work was to develop an easily injectable controlled release system intended to prolong the activity of anti-inflammatory drugs in the articular cavity. The system was an in situ forming hydrogel, made of fibrin and hyaluronic acid (HA), loaded with nanocapsules (NCs). The NCs, consisting of an olive oil core surrounded by a HA shell, were loaded with two different drugs, dexamethasone (DMX) and a galectin-3 inhibitor. They presented a particle size in the range of 122–135 nm and a surface charge of − 29/− 31 mV. The gelation time, rheological properties and porosity of the system could be adjusted by different parameters, such as addition of fibrin crosslinkers factor XIII and α2-antiplasmin. The non-crosslinked HA-fibrin hydrogels containing 30% (v/v) NCs showed the capacity to control the release of the encapsulated drug, DMX, for 72 h in simulated synovial fluid. The preliminary in vivo evaluation of the system containing a galectin-3 inhibitor in an acute synovitis rat model showed a suppression of inflammation after IA administration compared with the non-treated control.
