INCREASING ELECTRO-GENE TRANSFER OF NUCLEIC ACID MOLECULES INTO HOST TISSUE

摘要

A method of delivering a pharmaceutical agent, such as a nucleic acid molecule, to a vertebrate host is disclosed which comprises combining the synergistic steps of electrical stimulation with administration of a biologically active amount of hyaluronidase. Additionally, formulations whic h comprise hyaluronidase and a pharmaceutical agent, such as a nucleic acid molecule, are disclosed. The hyaluronidase preparation is preferably administered prior to or simultaneous with the pharmaceutical agent and in conjunction with an applied electrical stimulation, thus affecting increased transfer of the population of a pharmaceutical agent into the target tissue when compared to the affect of electrical stimulation alone. The combination of hyaluronidase administration and electrostimulation results in a substantial increase in the transfer of the pharmaceutical agent, such as a nucleic acid molecule, to the target vertebrate host tissue.
