Abstract: The disclosure provides molecules for use in compositions, medicaments and methods for the treatment or prevention of RSV infections, its symptoms and associated pathologies and potentially infections caused or contributed to by viral pathogens which do not bind or do not primarily bind sialic acid containing receptors during pathogenesis. Specifically, the disclosure is based on the finding that molecules with affinity for (or an ability to bind to) sialic acid (and in particular sialoglycoconjugates) on cell surfaces (these including sialic acid containing glycoproteins and cell surface sialic acid receptors), find utility in the treatment and/or prevention of symptoms, infections, diseases and/or conditions associated with respiratory syncytial vims (RSV).

Abstract: The present disclosure a cohort of sialic acid binding molecules which comprise one or more modified carbohydrate binding modules (CBMs). The modified CBMs reduce the risk of adverse events related to the host immune response and/or the production of anti-drug antibodies (ADAs). The modified CBMs can be used in therapy or as medicaments and find specific application as molecules for the modulation of an immune response and/or cell growth. The modified CBMs may also be used as adjuvants, for example mucosal adjuvants and in the treatment and/or prevention of cancer, sepsis and/or diseases caused or contributed to by a pathogen that binds cell surface sialic acid-containing receptors.
