A Phase I Safety and Immunogenicity Trial of the Facilitated HIV-1 Gag-Pol DNA Vaccine (APL-400-047, Apollon, Inc.) Given Intramuscularly by Needle and Syringe or Biojector 2000 Needle-Free Jet Injection System in HIV-1 Uninfected Adult Volunteers

• Status: Completed
• Trial end date: 2001-02-01

Summary

To evaluate the safety, tolerability and immunogenicity in humans of the APL-400-047 vaccine when administered intramuscularly by needle and syringe at 1 of 3 doses or by Biojector at the intermediate dose. [AS PER AMENDMENT 07/98: To evaluate the tolerability, safety, and immunogenicity of an increased dose in an additional group of volunteers.] DNA-based immunization mimics live-attenuated virus vaccination by stimulation of both the humoral and cellular arms of the immune system; thus, potentially providing the advantages of a live virus vaccination but without the potential risks. It is essential that novel vaccine strategies (including DNA-based immunizations) continue to be developed and enter Phase I human testing because to date, no candidate vaccine from any of the approximately 30 AVEG Phase I or II trials has progressed to a Phase III efficacy trial. Use of a Biojector jet gun for vaccine delivery may also have potential psychological, comfort, safety and immunologic advantages over the traditional needle and syringe method of delivery.
