HspE7: Lead Product Candidate for the Treatment of CervicalIntraepithelial Neoplasia (CIN)

A recently completed Phase 1 clinical trial of HspE7, a novel therapeuticcandidate intended for the treatment of precancerous and cancerous lesionscaused by the human papillomavirus (HPV), demonstrated an excellent safetyprofile, while providing compelling data to support HspE7's immunologicactivity. Based on the positive Phase 1 trial results, the next plannedinitiatives include Phase 2 clinical studies that will evaluate HspE7 as apotential treatment for both low-grade cervical dysplasia (CIN 1) andhigh-grade cervical dysplasia (CIN 2/3). The planned Phase 2 trials consistof multi-center, randomized, double-blind, placebo-controlled studies in theU.S., Canada, Europe and Latin America. For the CIN 2/3 study, protocoldevelopment, discussions with the U.S. Food and Drug Administration and siteevaluations have been completed. A second protocol for the CIN 1 indicationis near completion. Partnering or adequate financing are required for thetrials to be initiated.

Poly-ICR -- Proprietary Toll-like Receptor 3 Agonist

-- Partnering Poly-ICR -- Nventa is currently providing Poly-ICR throughMaterial Transfer Agreements to leading vaccine developers in the U.S. andabroad who are evaluating Poly-ICR for potential incorporation into a widerange of vaccine products.
