(More Information)
ProgramVGX-3100Study PhasePhase 3SummaryHPV-303 is a prospective, randomized, double-blind, placebo-controlled phase 3 study of VGX-3100 delivered intramuscularly (IM) followed by electroporation (EP) delivered with CELLECTRA™ 5PSP in adult women with histologically confirmed high-grade squamous intraepithelial lesions (HSIL) (cervical intraepithelial neoplasia grade 2 [CIN2] or grade 3 [CIN3]) of the cervix, associated with HPV-16 and/or HPV-18.

ProgramINO-4800Study PhasePhase 1SummaryThis is an open-label trial to evaluate the safety, tolerability and immunological profile of INO-4800 administered by intradermal (ID) injection followed by electroporation (EP) using CELLECTRA® 2000 device in healthy adult volunteers.
DiseaseHepatitis C
(More Information)
ProgramGLS-6150Study PhasePhase 1SummaryHepatitis C virus (HCV) is an enveloped, single strand, positive sense RNA flavivirus. Infection by HCV is typically chronic, although an estimated ~10-20% may spontaneously clear the virus. HCV affects between 1.3 - 2 billion individuals, or 2-3% of the global population. HCV has a seroprevalence of approximately 1% in developed countries such as the US and Korea. Chronic HCV infection leads to hepatic fibrosis and cirrhosis. This Phase I study will evaluate the safety, tolerability and immunogenicity of GLS-6150 administered intradermally (ID) followed by electroporation at 1.0 mg and 2.0 mg/dose assessing 3 and 4-dose regimens.

ProgramPENNVAX-GPStudy PhasePhase 1/2SummaryThe central premise of our program is that durable control of HIV in the absence of antiretroviral therapy ("remission") will require the generation of de novo potent and sustained HIV-specific CD8+ cell responses that target evolutionarily conserved epitopes. A multi-clade gag/pol/env DNA vaccine administered with an IL-12 DNA plasmid (PENNVAX, Inovio) has been studied for HIV prevention and is known to be both safe and highly immunogenic. In a randomized placebo-controlled study we will compare the immunogenicity and anti-reservoir activities of gag/pol DNA versus gag/pol/env DNA (both administered with IL-12). We will determine for the first time in established HIV disease whether presence of env in a DNA vaccine blunts T cell responses to more conserved Gag-specific and Pol-specific epitopes. We will also determine if Env-specific responses (which will presumably be mediated by antibodies and ADCC) have a measurable effect on reservoir.
DiseaseMetastatic Castration-resistant Prostate Cancer
(More Information)
ProgramINO-5151Study PhasePhase 1/2SummaryThis study is designed to evaluate multiple clinical hypotheses and mechanistically-defined combinations to evaluate the safety and efficacy of immunotherapy combinations in participants with mCRPC who have received prior secondary androgen receptor signaling inhibitor therapy (eg, abiraterone, enzalutamide, apalutamide).
