Abstract

Abstract The present invention discloses a new approach to the therapy of cancer in humans based on the administration of lymphokine activated killer (LAK) cells and interleukin-2 (IL-2). Twelve patients with metastatic cancer who had failed standard available therapy were treated. LAK cells were generated from peripheral blood mononuclear cells obtained at multiple leukaphereses and incubated in the recombinant-derived lymphokine, IL-2. Following three to four days of incubation in IL-2, the resulting LAK cells were capable of lysing fresh tumor cells but not normal cells. These LAK cells were reinfused into the autologous patient, along with the intravenous administration of recombinant IL-2 every 8 hours. Patients received up to 90 doses of IL-2 and from 2.8 to 12.6x1010 activated cells from up to 14 sequential leukaphereses. Six patients showed objective regression of established cancer.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 35 words
A method of treating cancer in humans comprising systemically administering to a human suffering from cancer other than sarcomas, an effective amount of interleukin-2 and interleukin-2-activated autologous human lymphocytes to cause regression of said cancer.
Claim 2
Independent Claim 35 words
A method of treating cancer in humans comprising systemically administering to a human suffering from cancer other than sarcomas, an effective amount of interleukin-2 and interleukin-2-activated autologous human lymphocytes to cause regression of said cancer.
Claim 3
Dependent Claim 20 words
The method of claim 1 wherein said cancer is melanoma, lung adenocarcinoma, renal cell cancer, colon cancer, or rectal cancer.
Claim 4
Dependent Claim 36 words
The method of claim 2 wherein the amount of interleukin-2 is in the range of about 1,000 to 10 6 units per kilogram body weight administered multiple times daily as tolerated by the human being treated.
Claim 5
Dependent Claim 23 words
The method of claim 2 wherein the amount of the lymphocytes is in the range of about 10 6 to 10 12 cells.
Claim 6
Dependent Claim 10 words

Claim 10
Dependent Claim 11 words
The method of claim 2 wherein said cancer is rectal cancer.
Claim 11
Independent Claim 49 words
A method of treating cancer in humans comprising intraveneously administering to a human suffering from cancer other than sarcomas about 10 6 to 10 12 interleukin-2-activated human lymphocytes and about 10 3 to 10 6 units, per kilogram body weight, of interleukin-2 multiple times as tolerated by said human.
Claim 12
Independent Claim 49 words
A method of treating cancer in humans comprising intraveneously administering to a human suffering from cancer other than sarcomas about 10 6 to 10 12 interleukin-2-activated human lymphocytes and about 10 3 to 10 6 units, per kilogram body weight, of interleukin-2 multiple times as tolerated by said human.
Claim 13
Dependent Claim 20 words
The method of claim 10 wherein said cancer is melanoma, lung adenocarcinoma, renal cell cancer, colon cancer, or rectal cancer.
