Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Functional and quantitative renal magnetic resonance imaging (MRI) has seen a number of recent advances, and techniques are now available that can generate quantitative imaging biomarkers with the potential to improve the management of kidney disease.

However, there are knowledge gaps that must be addressed before renal MRI methods could be more widely adopted in clinical research and ultimately be transferred to clinical practice, including the biological basis of different MRI biomarkers, and how the application of these biomarkers will improve patient care.

Among renal MRI techniques, renal diffusion weighted MRI (DWI) has been increasingly used in the last decade, showing high potential as a surrogate and monitoring biomarker for interstitial fibrosis in chronic kidney disease (CKD), as well as a surrogate biomarker for the inflammation in acute kidney diseases that may impact patient selection for renal biopsy in acute graft rejection.

Within the ready-to-start ACH471-205 clinical trial, an Open-Label Phase 2 Proof-of-Concept Study in Patients with C3 Glomerulopathy (C3G) or Immune-Complex Membranoproliferative Glomerulonephritis (IC-MPGN) treated with ACH-0144471, aimed at evaluating the efficacy of 12 months of oral ACH-0144471 in patients with C3G or IC-MPGN, patients will undergo baseline and 12-month follow-up renal biopsies, and renal function will be assessed over time by estimated or measured (when available) glomerular filtration rate (GFR). Adding multi-parametric NCE-MRI to the examinations under the ACH471-205 study protocol will give the opportunity to elucidate, in a well-defined cohort of patients, the potential of NCE-MRI as biomarker of renal microstructure and functional change.
