HEAL STUDY (Hepatic Encephalopathy and Albumin Study)
HEAL STUDY (Hepatic Encephalopathy and Albumin Study)
Patients with continued cognitive impairment after episodes of HE have few options beyond
 lactulose and rifaximin in the US. Therefore using IV albumin in a randomized, double-blind,
 placebo-controlled trial, which could beneficially impact inflammation, could be an
 additional approach to improve cognition.

 This 6 week trial will study changes in cognition, HRQOL and inflammation in patients with
 covert HE after prior overt HE using multiple IV albumin infusions vs. placebo.
Hepatic encephalopathy (HE) is a highly prevalent neuro-cognitive complication of cirrhosis
 characterized by cognitive dysfunction, and high rate of subsequent mortality and recurrence.
 HE also places a tremendous burden with a relentless increase in inpatient stay duration with
 charges topping $7244.7 million in 2009. There were almost 23,000 hospitalizations for HE in
 2009 and far more patients with HE who are being managed as an outpatient in the US. In the
 NACSELD (North American Consortium for the Study of End-Stage Liver Disease) experience
 supported by Grifols, HE in inpatients is an independent risk factor for mortality and also
 the leading cause of readmissions in patients with cirrhosis.

 HE has two major phases, an acute inpatient phase, where patients undergo evaluation for
 precipitating factors and HE treatment, and the post-discharge phase after HE resolution
 where the patient has a normal mental status but may be cognitively impaired. Furthermore, it
 is being increasingly recognized that even after the resolution of an acute HE episode with
 normal mental status and ability to understand and consent, patients do not regain their
 pre-HE cognitive function despite maximal therapy with the current standard of care. As many
 as 70% of patients with HE, despite standard of care, have residual significant cognitive
 impairments. Studies show that patients with HE, despite being on these medications which are
 standard of care, continue to have significant cognitive impairment translating into poor
 health-related quality of life (HRQOL), poor employment status, and very poor socio-economic
 status. This residual cognitive impairment is proportional to the number of HE episodes and
 places a heavy medical and socio-economic burden on patients, caregivers and society. In some
 cases, this approximates a dementia-like situation and makes this situation very difficult to
 manage.

 These patients have three options in the current therapeutic situation which can improve
 brain function. However all of these options have problems in widespread acceptance or
 eligibility. First, if the patients are hyponatremic, correction of hyponatremia using
 tolvaptan can help but tolvaptan is now not FDA-approved for cirrhosis. Second a selected
 group of patients can undergo porto-systemic shunt embolization if their MELD score is <11
 and they have a double shunt, which is the minority of individuals. Lastly a small trial done
 by our group showed improvement with fecal transplant but this requires several more years of
 study before this becomes mainstream.

 Therefore, there is a major need for treating this continued cognitive impairment for which
 there are currently no widely-available therapeutic agents available but which can improve in
 selected cases. A medication or strategy that shows improvement in this functioning will be
 rapidly assimilated into the therapeutic algorithm and will potentially affect several
 thousand patients and their caregivers who continue to suffer from this issue.

 There is strong evidence that this persistent cognitive impairment is accompanied by a
 sustained pro-inflammatory state that is not quenched by our current standard of care15.
 Ammonia, inflammation, endotoxemia, oxidative stress and endothelial dysfunction play an
 important role in the pathogenesis of HE. There is also evidence that in patients with
 advanced cirrhosis, i.e. those who are predisposed to HE, of reduction in albumin
 concentration and capacity to bind to these metabolites that precipitate HE.
