Study Endpoints

Primary Endpoints

Change in Early and Mild Alzheimer's Cognitive Composite (EMACC)
24 Weeks

Change from Baseline to Week 24 in the Early and Mild Alzheimer's Cognitive Composite (EMACC), a z-score composite of six neuropsychological tests (International Shopping List Test-Immediate Recall; Digit Span Forward/Backward; Category Fluency; Letter Fluency \[D-KEFS\]; Trail Making Test A and B; Digit Symbol Coding). Each component is standardized to the pooled baseline mean (0) and SD (1), then averaged. Higher scores indicate better cognitive performance; a positive change from baseline indicates improvement.

Frequently asked questions about XPro1595

What is XPro1595?

XPro1595 is an investigational small molecule developed by INmune Bio Inc. (ticker INMB) for Alzheimer disease. It is a Phase 2 candidate that has been studied in biomarker-selected patients with early Alzheimer disease and evidence of inflammation. It has received FDA Fast Track designation.

What is XPro1595 used for in Alzheimer disease?

XPro1595 is being developed for Alzheimer disease, specifically in patients selected for biomarkers of inflammation. Clinical testing has focused on early Alzheimer disease and related conditions including mild cognitive impairment. It is investigational and has not been approved for any indication.

What does XPro1595 target?

XPro1595 targets TNF, a cytokine involved in inflammatory signaling. By acting on this cytokine target, the small molecule is designed to address neuroinflammation, which is the rationale for testing it in biomarker-selected Alzheimer disease patients.

Who is developing XPro1595?

XPro1595 is being developed by INmune Bio Inc., which trades under the ticker INMB. The company is the sponsor of the clinical program evaluating the drug in Alzheimer disease.

What phase is XPro1595 in?

XPro1595 is in Phase 2 development. Two completed trials have evaluated it: a Phase 2 study in early Alzheimer disease with biomarkers of inflammation and an earlier Phase 1 biomarker-directed study. It is investigational and has not been approved by the FDA.

What clinical trials is XPro1595 in?

XPro1595 has been studied in two completed trials. NCT05318976 was a Phase 2 trial in early Alzheimer disease with biomarkers of inflammation that enrolled 207 patients across eight countries. NCT03943264 was a Phase 1 biomarker-directed study in Alzheimer disease that enrolled 20 patients in Australia.
