Active Research

Clinical Trials

International experts agree that most novel diagnostic and therapeutic techniques remain investigational and should be performed under an IRB-approved protocol and/or contribute to an IRB-approved registry – the HALO way. Below are HALO’s active and completed clinical trials, and related peer-reviewed publications.

Recruiting · NCT06112418

TRANSFORM Cardiovascular Prevention Study

A randomized, multi-center trial comparing the Cleerly Coronary Artery Disease (CAD) Staging System — which visualizes and quantifies coronary atherosclerosis — against traditional risk factor-based care for the primary prevention of cardiovascular events in patients with type 2 diabetes, prediabetes, or metabolic syndrome.

HALO Diagnostics (Indian Wells, CA) is a participating site, with Dr. John F. Feller as site contact. Sponsored by Cleerly, Inc. in collaboration with CPC Clinical Research; estimated enrollment of 7,500 patients nationwide.

Published Phase I Research · ISRCTN10201650

First-in-Human Oncolytic Vaccinia Virus Research

John F. Feller, MD and Bernadette M. Greenwood coauthored a first-in-human Phase I study investigating TK-positive oncolytic vaccinia virus delivered using autologous adipose stromal vascular fraction cells in people with advanced solid tumors or acute myeloid leukemia. The published early-phase study assessed feasibility and tolerability and supported additional research.
