Which antibiotic combo is safer for kidneys in serious hospital infections
Official title: A Randomized Controlled Trial Comparing Renal Effects of Vancomycin Combined With Either Piperacillin/Tazobactam or Meropenem: VPT Patient Safety (VPS) Study
Run by Bassett Healthcare · NCT07556107 · Data updated 2026-11-12
This trial tests whether vancomycin with piperacillin/tazobactam is gentler on the kidneys than other common broad-spectrum antibiotics for adults with serious infections in the hospital.

Is this trial a fit for you?
✓Likely a good fit
Adults (18+) hospitalized with a serious infection where VPT or VM are considered standard care options.
✕Probably not a fit
Patients with moderate-to-severe preexisting kidney disease or beta-lactam allergy may not benefit or could be excluded.

What this trial studies
The VPS trial compares two FDA-approved antibiotic regimens used for serious infections in hospitalized patients to see if one leads to more acute kidney injury (AKI). It uses kidney function tests, including cystatin C, to assess safety. The study aims to help doctors choose the safer option when treating severe infections in the hospital. Enrollment targets adults with suspected serious infection where VPT or VM could be used, and excludes those with moderate-to-severe preexisting kidney disease or beta-lactam allergy. The trial is conducted at multiple centers and led by Bassett Healthcare with collaboration from Johns Hopkins and PCORI.
Why it matters
Potential benefit: If successful, the trial could clarify which antibiotic strategy minimizes kidney injury, guiding safer prescribing for seriously ill patients.
How similar studies have gone: Prior research with improved kidney testing did not show a clear excess of kidney problems with VPT, but consensus remains unsettled and this study addresses that gap.

Inclusion criteria 1. Hospitalized or being hospitalized. 2. Age \>/=18 yr old. 3. Serious or suspected serious infection for which VPT or VM considered a broad-spectrum combination antibiotic backbone standard of care by clinician. 4. Enrollment can be completed before the first dose of abx (ideally) and no later than before the second dose (alternatively). 5. Consenting/enrollment will not clinically significantly delay abx administration. 6. Baseline and \>/=1 prior Scr available (within 1 yr). 7. Pt or LAR able to provide IC. Exclusion criteria 1\. AKI (\>/=moderate) (KDIGO stage 2-3) (Scr increase \>/=2-fold from chronic BL) (Scr based). 2\. CKD (\>/=moderately to severely decreased eGFR) (KDIGO stage G3b-G5) (by history or eGFR \</=44 mL/min/1.73M2) (Scr based). 3\. Beta lactam allergy. 4. Contraindication to VPT or VM. 5. Infection requiring VPT or VM specifically or another abx regimen. 6. Participation in another research study with interventions that may impact study endpoints.
