Brief Summary

Assess the Efficacy of HUEXC030 as Add-on Excipient to Eradicate Anti-Tuberculosis Drugs Induced Hepatic Injury ( ATDH ) in Subjects with Pulmonary Tuberculosis

Detailed Description

The study drug is Isoniazid formulated with HUEXC030 as excipient for eradicating ATDH, whereas the reference control is Isoniazid formulated with inactive excipient. Subjects who fulfill all the entry criteria and have written informed consent will be enrolled to the study. Eligible subjects will be randomized in a 1:1 ratio to receive study drug or reference control drug. Subjects will be genotyped according to a selected panel of single nucleotide polymorphisms (SNPs) and categorized into high risk or low risk groups for occurring ATDH via a specific haplotype consists of CYP2E1 and NAT2 SNPs. Based on an extensive study result during 2007 to 2011,the estimated frequency for patients bearing high risk genotypes in Taiwanese population is around 25%. Approximately 352 subjects will be enrolled for genotype screening in order to recruit 88 high risk subjects for each of 44 subjects in the intervention and control arms.

Subjects who are stratified as high risk groups will be administered the test drug or reference control drugs oral daily for 6 months or until treatment completion, i.e. bacteriologically confirmed negative of active M. tuberculosis. Subjects who are of low risk genotype will be removed from study after 8 weeks of study treatment, then return to conventional TB medication under the care of their investigator for at least one follow-up visit at 4 weeks after the End of Study.

IsoniazidHRZESubjects who are genotyped as high risk group will be receiving 2 months of intensive treatment comprised of 4 drugs (Isoniazid \[H\], rifampin \[R\], pyrazinamide \[Z\] and ethambutol \[E\]), followed by 4 months of continual chemotherapy consist of Isoniazid, Rifampin (2HRZE/4HR regimen). Subjects who are of low risk genotype will be removed from study after 8 weeks of study treatment, then return to conventional TB medication at least one follow-up visit at 4 weeks after the end of study treatment visit. Dosage is as below: Isoniazid (H):300mg daily, rifampin \[R\]: 450\~600mg daily, pyrazinamide \[Z\]; 1000\~2000mg daily and ethambutol \[E\]: 800-1600mg daily)

Primary Outcome Measures
NameTimeMethod
ALT change from baseline to the 8 weeks of study treatment8 weeks

The primary efficacy endpoint is the time-interval weighted area under the curve (AUC) of change from baseline in serum ALT, primarily in patients with high risk genotypes. The area under ALT change curve was estimated using the linear trapezoidal rule. The AUC was a measure of cumulative ALT differences from baseline to the 8 weeks of double-blind treatment period.

Secondary Outcome Measures
NameTimeMethod
Percentage of patients cured by the end of treatment26 weeks

At 26 weeks or at treatment completion, the investigational product is not inferior in effectiveness of TB treatment to the control drug, primarily in patients with high risk genotypes.

The overall reduced incidence of ATDH in subjects treated with investigational drugs26 weeks

Compared to control drugs, the overall reduced incidence of ATDH in all enrolled subjects treated with investigational drugs at study ends.

The lowering average level of liver function tests26 weeks

Compared to control drugs, the lowering average level of liver function tests in all enrolled subjects treated with investigational drugs at study ends.

Incidence of ATDH in high risk genotype subjects treated with investigational drugs26 weeks

Primarily in patients with high risk genotypes, the lowering incidence of ATDH in subjects treated with anti-TB drugs in combination with HUEXC030 for 26 weeks or at treatment completion.
