Abstract: The invention relates to RNA constructs encoding (i) at least one therapeutic biomolecule; and (ii) at least one innate inhibitor protein (IIP). The constructs are RNA replicons and saRNA molecules, and the invention includes genetic constructs or vectors encoding such RNA replicons. The invention extends to the use of such RNA constructs and replicons in therapy, for example in treating diseases and/or in vaccine delivery. The invention extends to pharmaceutical compositions comprising such RNA constructs, and methods and uses thereof.

Abstract: The disclosure provides a sub-micron particle comprising a first payload molecule, a lipid structure and a plurality of amphiphilic polymer chains surrounding the lipid structure. The first payload molecule is a macromolecule, optionally a nucleic acid. Additionally, the hydrophobicity of the amphiphilic polymer chains changes in response to an external stimulus.

Abstract: The invention relates to a sub-micron particle comprising a payload molecule and a lipid structure being surrounded by an outer layer comprising an amphiphilic copolymer. The invention extends to method of producing the sub-micron particle. The invention also encompasses pharmaceutical compositions and vaccines comprising the sub-micron particle and medical uses thereof.

Abstract: The invention relates to polymeric compositions, nanoparticles and vaccines comprising polymeric compositions. The invention extends to medical uses of the polymeric compositions, nanoparticles and vaccines. The invention further extends to methods of producing the polymeric compositions and nanoparticles.

Abstract: The invention relates to vaccines, and in particular, to vaccines for preventing, treating or ameliorating coronavirus infections, such as severe acute respiratory syndrome coronavirus (SARS), SARS-CoV-2 and Middle East respiratory syndrome-related coronavirus (MERS). The invention is especially concerned with self-amplifying RNA replicons and genetic constructs or vectors encoding such RNA replicons, and their use in vaccine delivery for preventing infections of coronavirus. The invention extends to pharmaceutical compositions comprising such RNA constructs, and methods and uses thereof.

Abstract: Described are drug delivery systems incorporating electrospun fibers that comprise and deliver physicochemically diverse drug compounds. Such fibers provide significant advantages in drug agent release, such as adaptability for solid dosage delivery to mucosal tissues. This is in addition to allowing for controlled drug release. Systems and methods for large-scale electrospinning productivity are described, including novel microarchitectures allowing for variable pharmacokinetics in drug release.
