Abstract

Randomized clinical trials are underway to evaluate the efficacy of novel agents targeting the alternative complement pathway in patients with C3G, a rare glomerular disease. The Kidney Health Initiative (KHI) convened a panel of experts in C3G to: (1) assess the data supporting the use of the prespecified trial endpoints as measures of clinical benefit; and (2) opine on efficacy findings they would consider compelling as treatment(s) for C3G in native kidneys. Two subpanels of the C3G Trial Endpoints Work group reviewed the available evidence and uncertainties for the association between the three prespecified endpoints -- (1) proteinuria; (2) estimated glomerular filtration rate (eGFR); and (3) histopathology -- and anticipated outcomes. The full work group provided feedback on the summaries provided by the subpanels and on what potential treatment effects on the proposed endpoints they would consider compelling to support evidence of an investigational product's effectiveness for treating C3G. Members of the full work group agreed with the characterization of the data, the evidence, and uncertainties, supporting the endpoints. Given the limitations of the available data, the workgroup was unable to define a minimum threshold for change in any of the endpoints that might be considered clinically meaningful. The workgroup concluded that a favorable treatment effect on all three endpoints would provide convincing evidence of efficacy in the setting of a therapy that targeted the complement pathway. A therapy might be considered effective in the absence of complete alignment in all three endpoints if there was meaningful lowering of proteinuria and stabilization or improvement in eGFR. The panel unanimously supported efforts to foster data sharing between academic and industry partners to address the gaps in the current knowledge identified by the review of the endpoints in the aforementioned trials.
