Methods and compositions for enhancing delivery of therapeutic agents to tissues
First Claim
1. A method for delivering a therapeutic agent to a tumor in a patient, which comprises the steps of:
- (a) administering a dose of an apoptosis inducing agent paclitaxel to a patient having a tumor;
(b) allowing a time ranging from between about 24 and about 96 hours to elapse for said apoptosis inducing agent to induce greater than about 20% reduced cell density in the tumor; and
(c) administering a dose of a therapeutic agent to said patient, such that the therapeutic agent is delivered to the tumor to a greater extent than if administered without said apoptosis inducing agent.

Abstract
The invention, at least in part, is directed to methods for enhancing delivery of therapeutic agents, such as macromolecules and drugs, into the interior of tissues, such as solid tissues or tumors. The method initially uses an apoptosis inducing agent, such as paclitaxel, in doses which create channels within the tissues, and enhance the penetration of therapeutic agents to the interior of the tissue. Current methods of treating tissues are often not effective because the therapeutic agents are not delivered to the interior of the tissue. By using the methods and the compositions of the current invention, therapeutic agents can be delivered to the interior of the tissue.
