Details and patient eligibility

About

his clinical trial was conducted to determine the non-inferiority and safety of prophylactic antiviral treatment of Tenofovir alafenamide (TAF) compared to Tenofovir disoproxil fumarate (TDF) in patients with malignant hematological diseases requiring prophylactic hepatitis B antiviral treatment. Confirm.

In the case of TAF, domestic evidence when used as a first-line treatment is insufficient, so in this clinical trial, the virus suppression effect compared to TDF during the first administration of TAF to patients with malignant hematological diseases requiring prophylactic hepatitis B antiviral treatment was investigated. We aim to secure non-inferiority and additionally confirm the safety of TAF's known advantages of reducing renal function damage and protecting bone function.
