Scale-up of a peptide therapy to help brain blood flow and inflammation in people at risk for Alzheimer’s-related dementias
Official title: Scale-up GMP Manufacturing of Extended-Release PNA5 for Treating Cognitive Impairment in Patients at-risk for Alzheimer's Disease-Related Dementias and Vascular Dementia
Funded at Proneurogen, INC. · NIH-11307341 · Data updated 2026-11-12
A small US-based project will scale up manufacturing of a new peptide medicine (PNA5) intended to help people at risk for Alzheimer’s-related dementia and vascular dementia by improving brain blood flow and reducing inflammation.

Who could benefit from this research
✓Could help
Adults at risk for Alzheimer's-related dementias or vascular cognitive impairment who could participate in future trials through standard screening.
✕Less likely to help
As this is a manufacturing-focused grant, direct patient benefits will come only if the therapy proceeds to human testing.
What this research studies
This grant focuses on producing larger, GMP-grade batches of PNA5, a peptide designed to act on Mas receptors in the brain’s blood vessels and support better brain blood flow. The work aims to translate promising preclinical results into a manufacturable therapy that could eventually be tested in people at risk for ADRD and VCID. It is a Phase I SBIR project centered on manufacturing readiness and early safety signals, with the goal of enabling future human studies. By ensuring scalable, compliant production, the project helps pave the way for potential treatments that target vascular contributions to cognitive impairment.
Why it matters
Potential benefit: If successful, this could enable clinical trials of a new peptide therapy to slow or prevent cognitive decline in people at risk for ADRD and VCID.
How similar studies have gone: Preclinical data suggest that targeting vascular inflammation and brain blood flow may support cognition, but human data are needed to confirm benefit.
