U.S. Renal Care Begins Enrollment for VOICE Trial Evaluating Vafseo® Outcomes in CKD Dialysis Patients

Exploring the VOICE Collaborative Clinical Trial for Vafseo® in CKD Patients

Akebia Therapeutics has recently embarked on an important clinical journey with the commencement of the VOICE collaborative trial, which aims to investigate the effects of Vafseo® (vadadustat) in patients suffering from chronic kidney disease (CKD) undergoing dialysis. Announced at the end of November 2024, this significant endeavor involves the first patient enrollment by U.S. Renal Care, aiming to provide critical insights into the treatment of anemia related to CKD.

Dr. Steven K. Burke, Chief Medical Officer of Akebia, expressed eagerness about the start of treatment for CKD anemia patients. The VOICE trial is designed to assess the safety and efficacy of Vafseo when administered thrice weekly, synchronizing with the dialysis schedule of the patients involved. This approach is significant as it may yield additional benefits for the patients while maintaining their routine care protocol.

In March 2024, Vafseo received FDA approval specifically for treating anemia due to CKD in adults who have been on dialysis for at least three consecutive months. It is designed for oral once-daily administration and is expected to be commercially available in the U.S. by January 2025.

Trial Objectives and Design

The VOICE trial plans to enroll around 2,200 participants who will be administered 300 mg of oral Vafseo tablets three times weekly. The preliminary aim is to assess Vafseo's efficacy with respect to all-cause mortality, evaluating its performance in comparison to standard care practices involving erythropoiesis-stimulating agents. Additionally, the trial will assess hospitalizations among the participants, providing a dual assessment of benefits associated with Vafseo use in this demographic.

The trial is expected to conclude approximately 18 months after the last patient is enrolled, promising to deliver fresh insights into the management of anemia in CKD patients on dialysis. The primary endpoint will focus on non-inferiority concerning all-cause mortality, whereas the secondary aim is to establish the superiority of Vafseo in reducing hospitalizations arising from timely interventions.

Background on Vafseo®

Vafseo® acts as a hypoxia-inducible factor prolyl hydroxylase inhibitor, stimulating the endogenous production of erythropoietin in a patient’s body to increase hemoglobin and red blood cell production. This medication has been approved in 37 countries so far, indicating its potential as a vital component in anemia management among CKD patients globally.

While Vafseo shows promising effectiveness, it carries certain safety warnings. There is an increased risk of significant cardiovascular events, particularly among patients targeting hemoglobin levels above 11 g/dL. Thus, careful monitoring and management of dosages will play a crucial role in patient outcomes.

Acknowledgments and Future Directions

The initiation of the VOICE trial is a collaborative success, particularly credited to Dr. Geoff Block and his team at U.S. Renal Care for their swift actions in patient consent and trial launch. Their dedication signifies a valuable contribution to the future of kidney disease treatment.

In conclusion, the VOICE trial embodies a promising step towards optimizing the management of anemia due to CKD in dialysis patients, enhancing patient quality of life, and potentially reshaping treatment methodologies upon Vafseo's launch in the market. As patient enrollment progresses, the medical community eagerly awaits the outcomes that could improve standards of care within nephrology.
