Genocea Announces Positive Top-Line Phase 2 Data for Genital Herpes Immunotherapy GEN-003
- Highly statistically significant 55 percent reduction in viral shedding rate with best dose -
- Company to host conference call at
In a planned secondary analysis to assess impact on patient-reported genital lesion rates, a self-assessed measurement of clinical disease, all dose groups, including the placebo group, demonstrated a statistically significant reduction from baseline.
"We are extremely pleased with these positive top-line results which have successfully allowed us to identify the optimal dose to advance into further trials," said
The Phase 2 study showed that GEN-003 was generally safe and well tolerated by patients, with no serious adverse events related to the vaccine. Safety data throughout the trial is monitored by an independent data safety monitoring board. Although reactogenicity increased with adjuvant dose, there was no difference in discontinuations in patient dosing due to adverse events across the different treatment arms.
"People living with genital herpes are seeking treatments that deliver on efficacy and provide them with peace of mind that they are at less risk of transmitting the infection to their sexual partners," said
About the GEN-003 Phase 2 Clinical Trial
The Phase 2 study enrolled 310 subjects from 17 institutions in
A prior Phase 1/2a clinical trial demonstrated, at the corresponding immediate post dosing 28-day observation period, a highly statistically significant 52 percent reduction in the viral shedding rate and a highly statistically significant 48 percent reduction in the genital lesion rate compared to baseline at a dose of 30 µg per protein/50 µg of Matrix-M2TM adjuvant.

Inducing a T cell response against HSV-2 is critical to treating the clinical symptoms of disease and controlling transmission of the infection. GEN-003 is a first-in-class T-cell directed immunotherapy designed to elicit both a T cell and B cell (antibody) immune response. The immunotherapy was designed using Genocea's ATLAS™ platform, which profiles the comprehensive spectrum of actual T cell responses mounted by humans in response to disease, to identify antigen targets that drive T cell response. GEN-003 includes the antigens ICP4 and gD2 along with Matrix-M2TM adjuvant, which Genocea licensed from Novavax, Inc.

About Genital Herpes
Genital Herpes affects more than 400 million people worldwide and causes recurrent, painful genital lesions. It can be transmitted to sexual partners, even when the disease is asymptomatic. Current genital herpes therapies only partially control clinical symptoms and viral shedding, a process which drives disease transmission. Incomplete control of genital lesions and transmission risk, expense and the perceived inconvenience of taking a daily medication are hurdles for long-term disease management. Immunity through T cells is believed to be particularly critical to the control and possible prevention of genital herpes infections.
Genocea is harnessing the power of T cell immunity to develop life-changing vaccines and immunotherapies. T cells are increasingly recognized as a critical element of protective immune responses to a wide range of diseases, but traditional discovery methods have proven unable to identify the targets of such protective immune response. Using ATLAS™, its proprietary technology platform, Genocea identifies these targets to potentially enable the rapid development of medicines to address critical patient needs. Genocea's pipeline of novel clinical stage T cell-enabled product candidates includes GEN-003 for genital herpes, GEN-004 for the prevention of infection by all serotypes of pneumococcus, and earlier-stage programs in chlamydia, genital herpes prophylaxis, malaria and cancer immunotherapy.
