Self-Replicating RNA-based Shingles Vaccine Candidate Launches Clinical Study

Immorna today announced that the first subject had been dosed in the Company's First-In-Human Phase 1 multi-center study of JCXH-105, a self-replicating RNA (srRNA) vaccine being developed for the prevention of Shingles.

The U.S. Food and Drug Administration (FDA) cleared its investigational new drug application on January 9, 2023, to conduct a Phase 1 multi-center study of JCXH-105.

NgocDiep Le, M.D., Ph.D., Global Chief Medical Officer of Immorna, commented in a press release on May 30, 2023, "If proven successful in clinical studies, JCXH-105 may become a valuable alternative to current standard-of-care to meet the large world-wide medical need for Shingles prevention."

"Due to its self-replicating nature, JCXH-105 may be effective at a significantly reduced dose level compared to non-replicating conventional mRNA vaccines and thereby may cause less reactogenicity and substantially reduce the cost of production."

"In addition, due to the synthetic nature of all JCXH-105 vaccine components, there are no raw material limitations or production bottlenecks."

This Phase 1 study is a randomized, double-blinded, multi-center, active-controlled study to assess the safety, immunogenicity, and determine the Recommended Phase 2 Dose for JCXH-105 for seniors.

In this study, JCXH-105 will be compared to GSK's U.S. FDA-approved Shingrix® vaccine.
