The present application relates to a method for enhancing the therapeutic index of a compound that is useful to treat tumors. More specifically, the present invention relates to a method for administering IL-2 to a tumor patient to maximize the therapeutic efficacy and minimize the toxicity.

Method for enhancing the anti-tumor therapeutic index of interleukin-2

A colony stimulating factor, CSF-1, is a lymphokine useful in treating or preventing bacterial, viral or fungal infections, neoplasms, leukopenia, wounds, and in overcoming the immunosuppression induced by chemotherapy or resulting from other causes. CSF-1 is obtained in usable amounts by recombinant methods, including cloning and expression of the murine and human DNA sequences encoding this protein.

Use of CSF-1 to treat tumor burden

Damage to cells, tissue and other body parts in a mammalian host may be treated by using a colony stimulating factor in conjunction with at least one biological modifier, which may be a free radical scavenger or a metabolic inhibitor. The biological modifier is preferably uric acid, buthionine sulphoximine, vitamin C, aspirin, or nordihydroguaiaretic acid. Such a combination may be used to treat, for example, cancer, infectious diseases, and damage caused by radiation therapy, high oxygen tension, and chemotherapy.

Damage to cells, tissue and other body parts in a mammalian host may be treated by using a tumor necrosis factor in conjunction with at least one biological modifier, which may be a free radical scavenger or a metabolic inhibitor. The biological modifier is preferably uric acid, buthionine sulphoximine, vitamin C, aspirin, or nordihydroguaiaretic acid. Such a combination may be used to treat, for example, cancer, infectious diseases, and damage caused by radiation therapy, high oxygen tension, and chemotherapy.

Damage to cells, tissue and other body parts in a mammalian host may be treated by using a lymphokine or cytotoxin in conjunction with at least one biological modifier, which may be a free radical scavenger or a metabolic inhibitor. The biological modifier is preferably uric acid, buthionine sulphoximine, vitamin C, aspirin, or nordihydroguaiaretic acid. Such a combination may be used to treat, for example, cancer, infectious diseases, and damage caused by radiation therapy, high oxygen tension, and chemotherapy.

Method for treating biological damage using a free-radial scavenger and

Anti-tumor activity in mammals can be augmented by administering to the mammalian host a synergistically effective amount of TNF and IL-2 or of TNF and IFN-.beta., or of TNF, IL-2 and IFN-.beta. in combination. The composition of TNF and IL-2 and/or IFN-.beta. may be prepared in vitro or administered separately to the host. If the TNF and IL-2 are administered sequentially, the TNF must be administered prior to the IL-2 to obtain synergy. The composition is useful for treating such cancers as mastocytoma, melanoma, leukemia, lymphoma, mammary adenocarcinoma, and pharyngeal squamous cell carcinoma.

Combination therapy using interleukin-2 and tumor necrosis factor

A colony stimulating factor, CSF-1, is a lymphokine useful in overcoming the immunosuppression induced by chemotherapy or resulting from other causes. CSF-1 is obtained in usable amounts by recombinant methods, including cloning and expression of the murine and human DNA sequences encoding this protein.

Uses of recombinant colony stimulating factor-1

Damage to cells, tissue and other body parts in a mammalian host may be treated by using a lymphokine or cytotoxin in conjunction with at least one biological modifier, which may be a free radical scavenger or a metabolic inhibitor. The lymphokine or cytotoxin is preferably tumor necrosis factor and the biological modifier is preferably uric acid, buthionine sulphoximine, vitamin C, aspirin, or nordihydroguaiaretic acid. Such a combination may be used to treat, for example, cancer, infectious diseases, and damage caused by radiation therapy, high oxygen tension, and chemotherapy.

Therapeutic combination of free-radical scavenger and tumor necrosis

Tumor necrosis factor and a suitable immuotoxin when administered simultaneously or in tandem produce a synergistic effect in treating tumor burden in warm-blooded animals. Methods and protocols for obtaining this syneristic effect are disclosed, as well as compositions effective in this treatment.

Combination therapy using antitumor immunotoxins with tumor necrosis

Anti-tumor activity in humans can be augmented by administering to the mammalian host a pharmacologically effective amount of mammalian IL-2 and at least one immunotoxin that binds selectively to human tumor cells. The IL-2 and immunotoxin are preferably administered separately to the host. The composition is useful for prophylactic or therapeutic treatment of such cancers as ovarian and breast cancer.
