Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The primary objective of this study is to characterize the long term (ie, 96 weeks of follow up) bone safety profile of open-label tenofovir disoproxil fumarate (tenofovir DF) treatment in CHB-infected adolescents. This includes prospectively evaluating and comparing the bone mineral density (BMD) change between CHB-infected adolescents 12 to \< 18 years of age treated with tenofovir DF in European treatment centers who are assigned to one of two schedules for renal and bone laboratory monitoring and BMD measurement.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Tenofovir DF + increased bone/renal monitoring

Participants will receive tenofovir DF, plus laboratory bone biomarker testing and lumbar spine and whole-body DEXA scans every 24 weeks from baseline to Week 96 (5 scans), and monitoring of renal function at 4 and 12 weeks after baseline and every 12 weeks thereafter. With the exception of an enhanced monitoring protocol for bone and renal outcomes, participants will be managed according to local standards of care.

Group Type OTHER

Tenofovir DF

Intervention Type DRUG

300 mg tablet administered orally once daily for up to 96 weeks

DEXA Scan

Tenofovir DF + prespecified bone monitoring

Participants will receive tenofovir DF, plus laboratory bone biomarker testing and lumbar spine and whole-body DEXA scans at baseline, Week 48, and Week 96. With the exception of pre-specified bone monitoring, participants will be managed according to local standards of care.
