Trial summary

The treatment of latent TB with 3HP is an important issue for the prevention of active TB. However, significant proportion of subjects receiving 3HP had adverse reaction. The main purpose of this observation study is to identify subjects who have higher risk to develop adverse reaction. Read more about this study

About this study

The treatment of latent TB with 3HP is an important issue for the prevention of active TB. However, significant proportion of subjects receiving 3HP had adverse reaction. The main purpose of this observation study is to identify subjects who have higher risk to develop adverse reaction. Clinical characteristics and biomarker will be used to predict adverse reaction.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. sTREM1 between >= grade 2 adverse reaction (SAR group) and< grade 2 adverse reaction (Non-SAR group)

    Measured: Change from Baseline sTREM1 at 2 weeks

  2. sTREM1 between >= grade 2 adverse reaction (SAR group) and< grade 2 adverse reaction (Non-SAR group)

    Measured: Change from Baseline sTREM1 at SARs

  3. sTREM2 between >= grade 2 adverse reaction (SAR group) and< grade 2 adverse reaction (Non-SAR group)

    Measured: Change from Baseline sTREM1 at 2 weeks

  4. sTREM2 between >= grade 2 adverse reaction (SAR group) and< grade 2 adverse reaction (Non-SAR group)

    Measured: Change from Baseline sTREM1 at SARs
