Background
The sodium–glucose cotransporter 2 inhibitor ertugliflozin (ERTU) lowers serum uric acid (UA) levels. Using data from the VERTIS CV trial (NCT01986881), the impact of ERTU on eGFR and albuminuria was investigated in patients by baseline serum UA levels.
Methods
Patients with type 2 diabetes and atherosclerotic cardiovascular disease were randomized (1:1:1) to ERTU 5 mg, 15 mg (doses pooled for analyses), and placebo (PBO). Patients were categorized by baseline UA quintile (Table). UA over time, eGFR slopes (chronic from Weeks 6 to 260), and the time to first event of progression of albuminuria were analyzed for ERTU versus PBO.
Results
At baseline, there were notable differences by UA subgroup, such as sex, UACR, eGFR and diuretic use (Table). ERTU was associated with reductions in UA over time in all baseline UA subgroups (Fig. A). Treatment with ERTU resulted in a significantly slower rate of yearly eGFR decline in all UA subgroups compared with PBO (P<0.001; Fig. B). ERTU was associated with a reduced risk of albuminuria progression in all UA subgroups compared with PBO (Fig. C; Pinteraction=0.34).
Conclusion
In VERTIS CV, ERTU reduced UA while attenuating eGFR decline and albuminuria progression, irrespective of baseline UA quintile.
