Study Details

Study Description

Brief Summary

Individuals with kidney failure receiving maintenance hemodialysis (HD) have high mortality rates, driven largely by cardiovascular causes. Volume-related factors are critical, modifiable contributors to cardiovascular complications. Reversing volume overload has been shown to improve blood pressure and cardiac remodeling. Use of loop diuretics may represent a pragmatic, low-cost, and low-burden strategy to improve outcomes in people receiving HD. Lack of data on optimal furosemide dosing, safety, and acceptability are barriers to expanded use. This study investigates whether oral furosemide is safe and effective at increasing urine volume in HD patients.

Study Design

• Study Type: Interventional
• Actual Enrollment: 39 participants
• Allocation: N/A
• Intervention Model: Single Group Assignment
• Intervention Model Description: This is a single-center (multi-clinic), open-label, non-randomized pilot study to test whether oral furosemide is safe and effective at increasing urine volume in HD patients. The study will consist of 2 periods: a 6-week dose escalation period (period 1) and a subsequent 12-week follow-up period (period 2). During period 1, all participants will receive escalating doses of furosemide as tolerated, and the short-term safety, tolerability, and efficacy of furosemide will be examined. During period 2, all participants will continue the maximally tolerated period 1 furosemide dose, and the acceptability of and adherence to furosemide and the longer-term safety and efficacy of furosemide will be examined.This is a single-center (multi-clinic), open-label, non-randomized pilot study to test whether oral furosemide is safe and effective at increasing urine volume in HD patients.

Intervention/Treatment

Experimental: Study drug administration: furosemide Study participants will receive furosemide oral tablets to be taken twice daily. During study period 1 (first 6 weeks), the drug dose will be escalated every 2 weeks if safe, tolerated, and acceptable to the participant. During study period 2 (subsequent 12 weeks), participants will take the maximum tolerated dose from study period 1, received every 4 weeks if safe, tolerated, and acceptable to the participant.

Drug: Furosemide (loop diuretic) Tablets; Open label dose escalation study of furosemide in people receiving maintenance hemodialysis. Participants will take furosemide oral tablets twice daily for 18 weeks. Doses will be titrated every 2 weeks for 6 weeks if safe, effective, tolerated, and accepted by the participant. First 2 weeks of the study: participants not taking oral furosemide at enrollment will take 80mg furosemide twice daily, those taking oral furosemide at enrollment will stay on their prescribed dose, and those taking another loop diuretic at enrollment will discontinue their prescription and take an equivalent oral furosemide dose. At week 4: dose escalation if tolerated (from 80mg to 120mg twice daily for the 1st group, and a 50% increased dose not >320mg/day for the 2nd & 3rd groups). At week 6: dose escalation if tolerated (from 120mg to 160mg twice daily for the 1st group, and a 50% increased dose not >320mg/day for the 2nd & 3rd groups). Final 12 weeks: all participants will take the maximum tolerated dose.

Study Results

Participant Flow

Arm/Group Title	Study Drug Administration: Furosemide
Arm/Group Description	Open label dose escalation study of furosemide in people receiving maintenance hemodialysis. Participants will take furosemide oral tablets twice daily for 18 weeks. This was a single-arm study with 2 periods. Period 1 is the dose escalation phase. During period 1 (first 6 weeks), the drug dose will be escalated every 2 weeks if safe, tolerated, and acceptable to the participant. Period 2 is the follow-up phase. During period 2 (subsequent 12 weeks), all participants will take the maximum tolerated dose from study period 1, received every 4 weeks if safe, tolerated, and acceptable to the participant. First 2 weeks of the study: participants not taking oral furosemide at enrollment will take 80mg furosemide twice daily, those taking oral furosemide at enrollment will stay on their prescribed dose, and those taking another loop diuretic at enrollment will discontinue their prescription and take an equivalent oral furosemide dose. At week 4: dose escalation if tolerated (from 80mg to 120mg twice daily for the 1st group, and a 50% increased dose not >320mg/day for the 2nd & 3rd groups). At week 6: dose escalation if tolerated (from 120mg to 160mg twice daily for the 1st group, and a 50% increased dose not >320mg/day for the 2nd & 3rd groups). Final 12 weeks: all participants will take the maximum tolerated dose (period 2). In this single-arm study, all participants received oral furosemide. The protocol was pre-specified to summarize outcome events as a single arm.

Title	Percentage of Participants Who Have a Defined Increase in 24-hour Urine Volume From Baseline to Week 5
Description	Participants will follow standard dialysis clinic protocols for 24-urine volume collection. Classifying participants as has having an increase in 24-hour urine volume will be contingent on the amount of urine the participant makes at baseline. Among participants with baseline 24-hour urine volume ≥200 mL: ≥25% increase in urine volume is considered an increase. Among participants with baseline 24-hour urine volume <200 mL: ≥50 mL increase in urine volume to a urine volume of at least 100 mL/24-hours is considered an increase. The percentage of participants who have a defined increase in 24-urine volume from baseline to week 5 will be determined.

During study period 1 (first 6 weeks), the drug dose will be escalated every 2 weeks if safe, tolerated, and acceptable to the participant. During study period 2 (subsequent 12 weeks), participants will take the maximum tolerated dose from study period 1, received every 4 weeks if safe, tolerated, and acceptable to the participant. Furosemide (loop diuretic) Tablets: Open label dose escalation study of furosemide in people receiving maintenance hemodialysis. Participants will take furosemide oral tablets twice daily for 18 weeks. Doses will be titrated every 2 weeks for 6 weeks if safe, effective, tolerated, and accepted by the participant. First 2 weeks of the study: participants not taking oral furosemide at enrollment will take 80mg furosemide twice daily, those taking oral furosemide at enrollment will stay on their prescribed dose, and those taking another loop diuretic at enrollment will discontinue their prescription and take an equivalent oral furosemide dose. At week 4: dose escalation if tolerated (from 80mg to 120mg twice daily for the 1st group, and a 50% increased dose not >320mg/day for the 2nd & 3rd groups). At week 6: dose escalation if tolerated (from 120mg to 160mg twice daily for the 1st group, and a 50% increased dose not >320mg/day for the 2nd & 3rd groups).

23 participants completed the week 19 pill counts. Thus, the analysis population is 23 participants.

Arm/Group Title	Study Drug Administration: Furosemide
Arm/Group Description	Study participants will receive furosemide oral tablets to be taken twice daily. During study period 1 (first 6 weeks), the drug dose will be escalated every 2 weeks if safe, tolerated, and acceptable to the participant. During study period 2 (subsequent 12 weeks), participants will take the maximum tolerated dose from study period 1, received every 4 weeks if safe, tolerated, and acceptable to the participant. Furosemide (loop diuretic) Tablets: Open label dose escalation study of furosemide in people receiving maintenance hemodialysis. Participants will take furosemide oral tablets twice daily for 18 weeks. Doses will be titrated every 2 weeks for 6 weeks if safe, effective, tolerated, and accepted by the participant. First 2 weeks of the study: participants not taking oral furosemide at enrollment will take 80mg furosemide twice daily, those taking oral furosemide at enrollment will stay on their prescribed dose, and those taking another loop diuretic at enrollment will discontinue their prescription and take an equivalent oral furosemide dose. At week 4: dose escalation if tolerated (from 80mg to 120mg twice daily for the 1st group, and a 50% increased dose not >320mg/day for the 2nd & 3rd groups). At week 6: dose escalation if tolerated (from 120mg to 160mg twice daily for the 1st group, and a 50% increased dose not >320mg/day for the 2nd & 3rd groups). Final 12 weeks: all participants will take the maximum tolerated dose.

Adverse Events

Time Frame	From the time informed consent was obtained to study participation end (up to 24 weeks).
Adverse Event Reporting Description	All participants received oral furosemide. Per protocol, adverse events were collected irrespective of dose received and were summarized as a single arm. Of those participants reporting severe or very severe patient-reported outcomes, only severe tinnitus and hearing change were study-defined adverse events per the study protocol.
Arm/Group Title	Study Drug Administration: Furosemide
Arm/Group Description	Open label dose escalation study of furosemide in people receiving maintenance hemodialysis. Participants will take furosemide oral tablets twice daily for 18 weeks. This was a single-arm study with 2 periods. Period 1 is the dose escalation phase. During period 1 (first 6 weeks), the drug dose will be escalated every 2 weeks if safe, tolerated, and acceptable to the participant. Period 2 is the follow-up phase. During period 2 (subsequent 12 weeks), all participants will take the maximum tolerated dose from study period 1, received every 4 weeks if safe, tolerated, and acceptable to the participant. First 2 weeks of the study: participants not taking oral furosemide at enrollment will take 80mg furosemide twice daily, those taking oral furosemide at enrollment will stay on their prescribed dose, and those taking another loop diuretic at enrollment will discontinue their prescription and take an equivalent oral furosemide dose. At week 4: dose escalation if tolerated (from 80mg to 120mg twice daily for the 1st group, and a 50% increased dose not >320mg/day for the 2nd & 3rd groups). At week 6: dose escalation if tolerated (from 120mg to 160mg twice daily for the 1st group, and a 50% increased dose not >320mg/day for the 2nd & 3rd groups). Final 12 weeks: all participants will take the maximum tolerated dose (period 2). All participants received oral furosemide. Per protocol, adverse events were collected irrespective of dose received and were summarized as a single arm.
