Abstract: The present invention relates to cross polymers composed at least of polysaccharides and polyamino acids, and more particularly to hydrogels composed of said cross polymers. The invention also relates to a process for preparing them, as well as their use in the delivery of active agents for pharmaceutical, diagnostic and/or dermo-cosmetic applications.

Abstract: The invention relates to 3-arms star-shaped polypeptides derivatives which are able to self-assemble to form bioresponsive nanometric globular structures with controllable size and shape. These multivalent constructs also present the ability of disassemble under specific physiological conditions and of linking to at least one active agent so that they can be used as carries in biomedical applications.

Abstract: Polyglutamates are well known to be highly biocompatible, biodegradable and multifunctional polymers, which have been already used as building blocks in polymer drug conjugates and polymeric micelles. Those systems have been applied to various medical applications ranging from therapy to molecular imaging. Furthermore a polyglutamic acid (PGA) paclitaxel conjugate has already entered clinical studies (Opaxio™ PGA-PTX conjugate currently in phase III of Clinical trials). In this context, a synthetic pathway to a plethora functional polyglutamates (homopolymers, block-co-polymers, tribocks) with well-defined structure, adjustable molecular weight (Mw) and low dispersity (D=Mw/Mn<1.2) applying the ring opening polymerization (ROP) of N-carboxyanhydrides (NCA) has been developed.

Abstract: The present invention is referred to novel polymeric conjugates to which at least it is linked a fibril disruptor agent and/or a aggregates blocking agent, and additionally a targeting moiety and/or a probe for therapy and diagnosis. In the polymer-drug conjugate, the polymeric platform transports at least one bioactive agent, selected from the group of anthracyclines antibiotics which includes tetracycline, rolitethracycline, minocycline and/or doxycycline and their derivatives, etc. . . . , able to disaggregate or break the amyloid fibrils and/or block the aggregates. This conjugate could contain in its structure one or several targeting moieties, which will provide an effective targeting of the polymer-drug conjugate to the selected diseased area for drug activity, increasing the therapeutic efficacy in the treatment of amyloidosis related diseases, including amyloidosis related to polyneuropathic disorders and neurodegenerative diseases like FAP and AD.

Abstract: Conjugates of a polymer having attached thereto an angiogenesis targeting moiety and a therapeutically active agent such as an anti-cancer agent or anti-angiogenesis agent, and processes of preparing same are disclosed. Pharmaceutical compositions containing these conjugates and uses thereof in the treatment of angiogenesis-related medical conditions such as cancer and cancer metastases are also disclosed.
