A Study of Oral Valcyte (Valganciclovir) in Pediatric Kidney Transplant Recipients

Phase 4
Completed
Conditions
Kidney Transplantation, Cytomegalovirus Infections
Interventions
Registration Number
NCT01376804
Lead Sponsor
Hoffmann-La Roche
Brief Summary

This open-label, single arm study will evaluate the tolerability and efficacy of Valcyte (valganciclovir) in the prevention of cytomegalovirus disease in pediatric renal transplant recipients. After transplantation, patients (aged 4 months to 16 years) will receive Valcyte orally daily for up to 200 days post-transplant and will be followed for 52 weeks post-transplantation.

GroupInterventionDescription
Valganciclovirvalganciclovir [Valcyte]Participants received a once daily oral dose (solution or tablets) of valganciclovir starting within 10 days of kidney transplant for up to 200 days post-transplant. Dose (in milligrams) was calculated using the algorithm \[7 \* Body Surface Area \* Creatinine Clearance\].
Primary Outcome Measures
NameTimeMethod
Number of Participants With Adverse Events (AE), Serious Adverse Events (SAE) or Withdrawal Due to AEs52 weeks

An AE was any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not considered related to the medicinal (investigational) product. Pre-existing conditions which worsen during a study were reported as AEs.

A SAE was any experience that: resulted in death, was life-threatening, required in-patient hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity, was a congenital anomaly/birth defect or was medically significant.

Secondary Outcome Measures
NameTimeMethod
Number of Participants With Cytomegalovirus (CMV) Infection in the First 52 Weeks Post-Transplant as Assessed by the Investigator52 weeks

A polymerase chain reaction (PCR) based assay or antigenaemia assay was used for the qualitative assessment of CMV viremia (presence of CMV in the blood) by each study center as part of the clinical assessment required for diagnosis of CMV infection.

Number of Participants With Cytomegalovirus (CMV) Disease in the First 52 Weeks Post-Transplant as Assessed by the Investigator52 weeks

A polymerase chain reaction (PCR) based assay or antigenaemia assay was used for the qualitative assessment of CMV viremia by each study center as part of the clinical assessment required for diagnosis of CMV infection. CMV disease included CMV syndrome or tissue invasive CMV. CMV syndrome required fever ≥ 38 degrees Celsius, severe malaise, leukopenia on 2 separate measurements, atypical lymphocytosis ≥ 5%, thrombocytopenia, elevation of hepatic transaminases and presence of CMV in blood. Tissue Invasive CMV required evidence of localized CMV infection in a biopsy or other appropriate symptom and relevant symptoms or signs of organ dysfunction.

Number of Participants With Peak Cytomegalovirus (CMV) Viral Load up to Week 52 Post-Transplant52 weeks

Blood samples were sent to a central lab for the quantitative assessment of CMV viral load (amount of CMV in the blood) by an FDA-approved molecular-based assay. The number of participants in each category is reported in copies/milliliter (CP/mL). CMV DNA is detected in all categories \< 150 CP/mL and above.

Number of Participants With Biopsy Proven Rejection52 Weeks

Renal biopsies were performed as medically indicated. Biopsies were assessed histologically using the updated Banff criteria 1997.

Number of Participants With Graft Loss52 Weeks

Graft loss was defined as the institution of chronic dialysis (at least 6 consecutive weeks), transplant nephrectomy, or retransplantation.

Number of Participants With Death52 Weeks
Number of Participants With Known Ganciclovir Resistance (Mutations in Either UL54 or UL97 Genes)52 Weeks

All patients with measurable CMV had both UL54 and UL97 genes sequenced to assess for known CMV resistance to ganciclovir.
