Phase 1 Study of a Self-amplifying RNA Vaccine (ITI-5000) in Stage 2-3 Triple Negative Breast Cancer (NCT07652242)
A Phase 1, Multicenter, Open-label, First-in-Human Study of ITI-5000 (Self-Amplifying RNA Vaccine) Alone and in Combination With Standard of Care Adjuvant Therapy in Participants With Stage II-III Triple-Negative Breast Cancer (TNBC)
🩺 Plain-English Summary (8th-Grade Level)
This study tests an investigational cancer vaccine called ITI-5000 in people who have completed standard treatment for early-stage triple-negative breast cancer (TNBC). ITI-5000 is a self-amplifying RNA (saRNA) vaccine that instructs the immune system to recognize and attack cancer cells expressing two proteins found on TNBC cells-HERV-K and CT83-fused with a molecule called LAMP-1 that helps the immune system respond more strongly. The vaccine is delivered inside lipid nanoparticles (LNPs), similar to other approved mRNA vaccines. The study has two parts: * Part A: Participants receive ITI-5000 alone at one of two dose levels (1 µg or 10 µg), given as an injection into the upper arm muscle every 28 days for 3 doses total. The goal is to find the safest dose. * Part B: Participants receive ITI-5000 at the best dose identified in Part A, combined with the following approved immunotherapy drugs pembrolizumab (Keytruda) and either olaparib or capecitabine.
