  • Patent number: 9981007
    Abstract: A drug and/or pharmaceutical composition comprising recombinant mistletoe lectins for treating metastatic tumors, including malignant melanoma such as stage IV malignant melanoma, and use of said drug, particularly in select patient populations, are described. Recombinant mistletoe lectin polypeptides can be a mistletoe lectin A-chain or fragments thereof. Alternatively, the recombinant mistletoe lectin polypeptides can be mistletoe lectin B-chain or fragments thereof. The drug can be used for the treatment of stages III and IV of a metastatic tumor or skin cancer, as well as to treat non-responders and therapeutic failures of a standard tumor therapy. The drug can be used in a dosage in a range of 3-7 ng recombinant mistletoe lectin per kg body weight. The dosage of the recombinant mistletoe lectin can also be 200-500 ng, independently of body weight. The drug can be administered once a week, or more frequently.
