James McCullough, Chief Executive Officer of Renalytix, commented: "We are pleased with the breadth of cost reductions we have been able to achieve in this fiscal year, as we continue our work to align the business for commercial adoption with the inclusion of KidneyIntelX in clinical guidelines.  We are fortunate to have crossed all the key milestones necessary to become a standard of care in chronic disease - FDA approval, broad reimbursement, outcomes data and clinical guidelines. We are incredibly grateful to O. James Sterling for his contribution to Renalytix since inception, but we now move into a new phase for the business. Whilst we remain focused on optimizing shareholder value, we are now well-positioned to become a sales and marketing play in a large and open market space."
