Abstract
The present invention includes vaccine compositions and methods for using these vaccine compositions in active immunotherapy. The vaccine compositions include allogeneic activated Th1 memory cells. The compositions can also include one or more disease-related antigens. The methods include administering the vaccine compositions to provide a Th1 footprint in normal individuals or patients susceptible to disease or having minimal residual disease.
Claims19
A method for treating an individual susceptible to a disease comprising:
- developing an anti-alloantigen immunity in an individual by administering a priming composition comprising allogeneic activated Th1 memory cells to the individual, wherein the individual's immune system increases the titer of the circulating anti-alloantigen specific Th1 cells, the priming composition administered prophylactically, prior to onset of disease in the individual, the allogeneic Th1 memory cells activated by the cross-linking of CD3 and CD28 surface molecules at the time of formulation and administration, the priming composition comprising allogeneic Th1 memory cells, and cross-linking agents for cross-linking the CD3 and CD28 surface moieties on the Th1 memory cells, wherein the anti-alloantigen immunity is developed in the individual prior to administration of disease-related antigens;
- and
- administering an activating composition comprising allogeneic activated Th1 memory cells and the one or more disease-related antigens to the primed individual, wherein the activating composition is administered at or after the onset of the disease in the individual.
A method of reducing tumor recurrence in an individual comprising:
- developing an anti-alloantigen immunity in the individual when the individual is not exhibiting symptoms from the tumor-related disease by administering a priming composition causing increased Th1 anti-alloantigen specific titer in circulation by the individual's immune system, the priming composition comprising allogeneic activated Th1 memory cells and cross-linking agents for cross-linking the CD3 and CD28 surface moieties on the Th1 memory cells, wherein the allogeneic Th1 memory cells are activated by the cross-linking of CD3 and CD28 surface molecules at the time of administration, wherein administration of the priming composition causes increased Th1 anti-alloantigen specific titer in circulation;
- and
- administering one or more tumor-related antigens to the primed individual, wherein the priming composition and the one or more tumor-related antigens are administered prior to tumor recurrence in the individual.
