Background:
The lack of adequate randomized clinical trials (RCT) has hindered identification of new therapies that are safe and effective for patients with primary focal segmental glomerulosclerosis (FSGS), especially in patients who fail to respond to corticosteroids and immunosuppressive therapies. Recent basic science advances have led to development of alternative treatments that specifically target aberrant pathways of fibrosis which are relevant to disease progression in FSGS. There is a need for a flexible Phase II study design which will test such novel antifibrotic strategies in order to identify agents suitable for phase III testing.
Methods/Design:
The Novel Therapies for Resistant Focal Segmental Glomerulosclerosis (FONT) project is a multicenter Phase I/II RCT designed to investigate the potential efficacy of novel therapies for resistant FSGS. Adalimumab and galactose will be evaluated against conservative therapy consisting of the combination of lisinopril, losartan and atorvastatin. The sample size is defined to assure that if one of the treatments has a superior response rate compared to that of the other treatments, it will be selected with high probability for further evaluation. Comparison of primary and secondary endpoints in each study arm will enable a choice to be made of which treatments are worthy of further study in future Phase III RCT.
Discussion:
This report highlights the key features of the FONT II RCT including the two-step outcome analysis that will expedite achievement of the study objectives. The proposed phase II study design will help to identify promising agents for further testing while excluding ineffective agents. This staged approach can help to prevent large expenditures on unworthy therapeutic agents in the management of serious but rare kidney diseases.
Insights
This study introduces a flexible Phase II trial design to identify effective antifibrotic therapies for focal segmental glomerulosclerosis (FSGS). The Novel Therapies for Resistant Focal Segmental Glomerulosclerosis (FONT) project aims to find promising treatments for future Phase III trials.
Area of Science:
- Nephrology
- Clinical Trial Design
- Pharmacology
Background:
- Primary focal segmental glomerulosclerosis (FSGS) lacks sufficient randomized clinical trials (RCTs) for novel therapies, particularly for corticosteroid-resistant cases.
- Advances in basic science offer new antifibrotic strategies targeting fibrosis pathways relevant to FSGS progression.
- There is a critical need for adaptable Phase II study designs to evaluate these novel antifibrotic agents.
Purpose of the Study:
- To investigate the efficacy of novel therapies for resistant FSGS using a multicenter Phase I/II RCT.
- To identify agents with superior response rates for further evaluation in Phase III trials.
- To efficiently select promising treatments and exclude ineffective ones for FSGS management.
Main Methods:
- The Novel Therapies for Resistant Focal Segmental Glomerulosclerosis (FONT) project is a multicenter Phase I/II RCT.
- Adalimumab and galactose will be compared against a conservative therapy (lisinopril, losartan, atorvastatin).
- A two-step outcome analysis will be employed to expedite the selection of agents for Phase III testing.
Main Results:
- The study is designed to have high probability of selecting a superior treatment if one exists.
- Comparison of primary and secondary endpoints across study arms will guide the choice of treatments for future Phase III RCTs.
- The sample size is calculated to ensure statistical power for treatment selection.
Conclusions:
- The FONT II RCT utilizes a two-step outcome analysis to accelerate the identification of effective FSGS therapies.
- This phased approach efficiently identifies promising agents for Phase III testing while discarding ineffective ones.
- The study design aims to prevent significant investment in non-efficacious treatments for rare kidney diseases like FSGS.
