NCT06538077

Brief Summary

Rationale

  • Patients who recover from an episode of overt HE(OHE) are at risk of recurrent episodes of HE and persistent minimal hepatic encephalopathy, impacting their daily functioning and mental health.
  • A multicentric pan-India team will evaluate the role of oral branched-chain amino acids (BCAA) vs Rifaximin as secondary prophylaxis following overt HE as compared with improvement in cognitive function. Novelty:
  • This study is intended to investigate the role of BCAA vs rifaximin as the ideal second-line therapy for HE management, recurrence, and overall health, including cognitive function, depression and anxiety.
  • The head-to-head comparison of BCAA+lactulose+ pill-placebo vs rifaximin+ lactulose+ powder-placebo ensures minimization of bias and has adequate power to determine rates of recurrence, Objectives:
  • To assess the 1st breakthrough episode of HE during 6months in BCAA vs rifaximin groups as ideal secondary prophylaxis in HE. Methodology
  • Double-blind placebo-controlled double-dummy randomized trial of BCAA supplementation vs rifaximin as the ideal second-line therapy in patients with cirrhosis who have recovered from an episode of OHE. Expected Outcome
  • Ideal second line agent HE prophylaxis (rifaximin or BCAA) following 1st line lactulose is unclear in an Indian context where dysbiosis and sarcopenia are prevalent, and cost of therapy needs to be optimized.
  • Optimal HE management prevents recurrence episodes of HE, and improves prognosis, neurocognitive function, and overall health-related quality of life(HRQOL).
  • Creation of a management algorithm based deductive models incorporating etiology and severity of liver disease, cognitive performance, sarcopenia, and ammonia, and neuropsychiatric impact of using BCAA vs Rifaximin will be created.

Outcome Measures

Primary Outcomes (1)

  • Number of breakthrough event of overt hepatic encephalopathy in BCAA vs rifaximin arm
