- 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.

Group Intervention Description Isoniazid HRZE Subjects 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) Isoniazid with HUEXC030 and RZE Isoniazid with HUEXC030 and RZE Subjects who are genotyped as high risk group will be receiving 2 months of intensive treatment comprised of 4 drugs (Isoniazid with HUEXC030 \[H\], 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 with Isoniazid(H):300mg/600mg daily, rifampin \[R\]: 450\~600mg daily, pyrazinamide \[Z\]; 1000\~2000mg daily and ethambutol \[E\]: 800-1600mg daily)
- Primary Outcome Measures
Name Time Method ALT change from baseline to the 8 weeks of study treatment 8 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
Name Time Method Percentage of patients cured by the end of treatment 26 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 drugs 26 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 tests 26 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 drugs 26 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.
