The present disclosure relates to, inter alia, antibodies, or antigen-binding fragments thereof, that bind to C5a and to use of the antibodies in methods for treating or preventing complement-associated disorders such as, but not limited to, atypical hemolytic uremic syndrome, age-related macular degeneration, rheumatoid arthritis, sepsis, severe burn, antiphospho lipid syndrome, asthma, lupus nephritis, Goodpasture's syndrome, and chronic obstructive pulmonary disease.

In some aspects, the present invention cell-penetrating compstatin analog and compositions comprising cell-penetrating compstatin analog. In some aspects, the invention further provides methods of using cell-penetrating compstatin analogs treat a complement-mediated disorder. e.g., to inhibit complement-mediated damage to a cell, tissue, or organ, to inhibit production or release of biologically active C3 cleavage products.

Recombinant vectors operably encoding a CR2-FH fusion protein comprising a CR2 portion comprising CR2 protein or a fragment thereof and a FH portion comprising a factor H protein or a fragment thereof, and pharmaceutical compositions comprising the recombinant vector, are described. Also provided are methods of using the compositions for treatment eye diseases such as macular degeneration or glaucoma.

The disclosure relates to methods of enhancing aqueous humor out-flow via the conventional outflow tract in the eye in a subject in need thereof, or reducing intraocular pressure in a subject in need thereof.

The invention relates to Factor H gene polymorphisms and haplotypes associated with an elevated or a reduced risk of AMD. The invention provides methods and reagents for diagnosis and treatment of AMD.

Compstatin analogues having improved binding and complement-inhibiting activity as compared to the 13 amino acid compstatin peptide (ICVVQDWGHHRCT (cyclic C2-C12)) are described, in particular compstatin analogues that additionally possess useful physicochemical properties, such as increased solubility. These analogues include variants with an isoleucine residue at position 3 in place of the wild type valine residue, which provides compstatin peptides with improved binding and complement-inhibiting activity and also enables the introduction of other modifications, for example modifications that are capable of increasing solubility, such as the introduction of charged or polar amino acids at position 9 and/or the introduction of N- and/or C-terminal sequences.

This invention relates to factor B inhibitors or nucleic acid molecules encoding thereof and selective inhibition of the alternative pathway (AP) of the complement system using said factor B inhibitors or nucleic acid molecules encoding thereof or compositions thereof. The invention also provides methods of treating an AP complement-mediated disease or AP complement-mediated disorder in a subject by administering a therapeutically effective amount of the factor B inhibitor or nucleic acid molecules encoding thereof or composition thereof.

The present invention relates to recombinant factor H and variants and conjugates thereof and methods of their production, as well as uses and methods of treatment involving the materials.

The present invention relates to novel ficolin-associated polypeptides, and polypeptides derived from these ficolin-associated polypeptides for the use in the treatment of conditions associated with inflammation, apoptosis, autoimmunity, coagulation, thrombotic or coagulopathic related diseases, as well as the use as biomarkers. The present invention further relates to antibodies recognising such novel ficolin-associated polypeptides, and polypeptides derived thereof, nucleic acid molecules encoding such polypeptides, vectors and host cells used in the production of the polypeptides.

An approach for modifying multiple types of bacteria to produce surface modifications that enhance the immunologic response when used as a vaccine. A series of plasmids (pYF, pYFC, pYFP, pSF, pSPF, and pSCF) may be used to transform bacteria which then produce surface-exposed ligands that bind to complement receptors on antigen presenting cells. When modified bacteria are used as a vaccine, the vaccine recipients produce significantly higher titers of specific antibodies and are better protected against challenges from the disease-causing bacteria.
