The present invention provides a compound, preferably a peptide, having the following characteristics:

Immune checkpoint inhibitor combinations

The present invention provides a compound, preferably a peptide, having the following characteristics: a) consisting of 9 amino acids in a linear arrangement; b) of those 9 amino acids, 5 are cationic and 4 have a lipophilic R group; c) at least one of said 9 amino acids is a non-genetically coded amino acid (e.g. a modified derivative of a genetically coded amino acid); and optionally d) the lipophilic and cationic residues are arranged such that there are no more than two of either type of residue adjacent to one another; and further optionally e) the molecule comprises two pairs of adjacent cationic amino acids and one or two pairs of adjacent lipophilic residues; for use in the treatment of a tumour by combined, sequential or separate administration with a cytotoxic chemotherapeutic agent that inhibits immune tolerance, wherein the chemotherapeutic agent is administered at a sub-cytotoxic dose. The present invention further provides pharmaceutical packs or compositions comprising these active agents and methods of treating a tumour comprising administration of these active agents.

Chemotherapeutic combinations of cationic antimicrobial peptides and chemotherapeutics

The present invention provides a compound, preferably a peptide, having the following characteristics: a) consisting of 9 amino acids in a linear arrangement; b) of those 9 amino acids, 5 are cationic and 4 have a lipophilic R group; c) at least one of said 9 amino acids is a non-genetically coded amino acid (e.g. a modified derivative of a genetically coded amino acid); and optionally d) the lipophilic and cationic residues are arranged such that there are no more than two of either type of residue adjacent to one another; and further optionally e) the molecule comprises two pairs of adjacent cationic amino acids and one or two pairs of adjacent lipophilic residues; for use in the treatment of a tumour by combined, sequential or separate administration with an immune checkpoint inhibitor. The present invention further provides pharmaceutical packs or compositions comprising these active agents and methods of treating a tumour comprising administration of these active agents. Also provided are the peptidic compounds as defined above for use in the destabilisation of a mitochondrial membrane, and a peptidic compound as defined above and an immunotherapeutic agent as a combined preparation for separate, simultaneous or sequential use in treating tumours.
