Abstract: The invention relates to methods of sonodynamic therapy comprising the co-administration of a microbubble-chemotherapeutic agent complex together with a microbubble-sonosensitiser complex. It further relates to pharmaceutical compositions comprising these complexes and their use in methods of sonodynamic therapy and/or sonodynamic diagnosis. Such methods find particular use in the treatment of cancer, e.g. pancreatic cancer.

Abstract: The invention relates to a microbubble-chemotherapeutic agent complex comprising a microbubble carrying a combination of chemotherapeutic agents for use in a method of treating cancer in a patient, wherein said combination of chemotherapeutic agents comprises: (a) a 5-fluoropyrimidine or a derivative thereof; (b) irinotecan or a derivative thereof; and (c) a platinum-based chemotherapeutic agent or a derivative thereof; and wherein said method comprises simultaneous, separate or sequential administration of folinic acid or a derivative thereof. The invention is particularly suitable for use in the treatment of deep-sited tumours and associated metastatic disease, for example in the treatment of pancreatic cancer. The invention further relates to the microbubble- chemotherapeutic agent complexes themselves, to methods for their preparation and to pharmaceutical compositions which contain them, optionally in combination with folinic acid or a folinic acid derivative.
