Current Primary Outcome Measures  ICMJE
 (submitted: March 2, 2020)
  • Time (weeks) to decrease of BKV plasma viral load by 1 log [ Time Frame: Study Week 1 - Study Week 12 ]
    The efficacy of MAU868 in treating BK viremia will be measured primarily by measuring the BK Viral Load in the plasma over time.
  • Time (weeks) to first decrease of BKV plasma viral load to less than Lower Limit of Quantification (LLOQ) [ Time Frame: Study Week 1 - Study Week 12 ]
    The efficacy of MAU868 in treating BK viremia will be measured primarily by measuring the BK Viral Load in the plasma over time.

Brief Title  ICMJE A Safety, Pharmacokinetics and Efficacy Study of MAU868 for the Treatment of BK Viremia in Kidney Transplant Recipients
Official Title  ICMJE A Randomized, Double-blind, Placebo-controlled Study to Assess the Safety, Pharmacokinetics and Efficacy of MAU868 for the Treatment of BK Viremia in Kidney Transplant Recipients (Neutra4)
Brief Summary This clinical research study will test the safety and efficacy of the investigational medication MAU868, compared to a placebo, in patients who have had a kidney transplant who have active BK virus.
Detailed Description Not Provided
Study Type  ICMJE Interventional
Study Phase  ICMJE Phase 2
Study Design  ICMJE Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Triple (Participant, Care Provider, Investigator)

Condition  ICMJE BK Virus Infection
Intervention  ICMJE
  • Drug: MAU868
    MAU868 is a human monoclonal antibody (IgG1) that binds the viral capsid protein, VP1, that is responsible for binding to the surface of host cells
  • Other: Placebo
    250 mL D5W placebo IV to be labeled to match that of MAU868
Study Arms  ICMJE

    Cohort 1: MAU868 1350 mg IV approximately every 28 days for a total of 4 doses
    Intervention: Drug: MAU868
  • Experimental: Cohort 2
    Cohort 2: MAU868 6750 mg IV on Study Day 1 and then 1350 mg IV approximately every 28 days for a total of 4 doses
    Intervention: Drug: MAU868
  • Experimental: Cohort 3
    Cohort 3: MAU868 6750 mg IV approximately every 28 days for a total of 4 doses
    Intervention: Drug: MAU868
  • Placebo Comparator: Placebo Cohort 1, 2, 3
    5% dextrose in water [D5W] IV delivered every 28 days for a total of 4 doses
    Intervention: Other: Placebo
