A Phase 1 interventional study of 12mg clofutriben in Moderate Renal Impairment, sponsored by Sparrow Pharmaceuticals. Recruiting at 1 site in United States. Open to participants aged 18 Years to 83 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2025-12-23.
Sponsored by Sparrow Pharmaceuticals · Phase 1, Interventional, and Treatment
This is a Phase 1, single-center, open-label, single-dose trial. Sixteen participants are planned: 8 participants with moderate renal impairment and 8 matched control participants with normal renal function.
Following Screening, enrolled participants will be confined to a clinical research unit for 6 days. Each participant will receive a single oral dose of clofutriben. Clofutriben PK, safety, and tolerability will be assessed. The participants will be contacted by telephone 4 weeks after clofutriben administration for safety follow-up.
Sparrow Pharmaceuticals is the lead sponsor of 8 studies on the registry; 2 are open to participants now.
Of its 6 completed or terminated interventional studies of FDA-regulated products, 0 (0%) have results posted.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².
Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.
Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.
A recording of the heart’s electrical activity, taken with stickers on the chest, arms and legs. It takes a few minutes and does not hurt.

Drug: 12mg clofutriben
Each participant will receive a single oral dose of clofutriben
1. Maximum plasma concentration (Cmax)
Conclusions that clofutriben and AS2570469 exposures (separately) are not altered by moderate renal impairment will be reached if the 95% CIs of the geometric mean estimates of AUC0-t, AUC0-inf, and Cmax of clofutriben and AS2570469 fall within the \[60%, 140%\] range.
Time frame: from enrollment through treatment for 6 days.
2. Area under the plasma time-concentration curve (AUC0-t, AUC0-inf)
Conclusions that clofutriben and AS2570469 exposures (separately) are not altered by moderate renal impairment will be reached if the 95% CIs of the geometric mean estimates of AUC0-t, AUC0-inf, and Cmax of clofutriben and AS2570469 fall within the \[60%, 140%\] range.
