Details and patient eligibility

About

This is a randomized, single blind study to determine whether AXA1125 or AXA1957, novel compositions of amino acids, are safe and well tolerated. Subjects have non-alcoholic fatty liver disease (NAFLD) and the study will also examine liver biology using blood tests and magnetic resonance imaging (MRI).

Full description

This was a 16-week, single-blind, randomized, placebo-controlled food study of the safety and tolerability of AXA1125 and AXA1957 in subjects with NAFLD.

Subjects signed an informed consent form and were screened for eligibility, per the inclusion and exclusion criteria below, up to 6 weeks before the start of the administration period. Subjects were randomized as soon as eligibility was confirmed.

Eligible subjects were randomized in a 2:2:2:1 ratio to receive either AXA1125 24 g twice daily (BID), AXA1957 20.3 g BID, AXA1957 13.5 g BID, or placebo 24 g BID. Randomization occurred via an interactive web response system after eligibility was confirmed and approximately 3 to 5 days prior to the Day 1 visit. Assigned study food product (AXA1125, AXA1957, or placebo) were shipped to the study site upon randomization of each subject.

Once randomization had occurred, subjects presented to the study site on Day 1 (Baseline/Visit 2) for their baseline assessments per the schedule of events. Study Day 1 was the beginning of the 16-week administration period.

Subjects returned to the study site at Week 1 (Visit 3), Week 2 (Visit 4), Week 4 (Visit 5), Week 8 (Visit 6), Week 12 (Visit 7), and Week 16 (Visit 8) to receive their study food product and/or to return any unused study food product, provide blood samples for biomarker and other laboratory testing, undergo liver imaging, and complete other study safety assessments per the schedule of events.

The Safety Follow-up Visit, which occurred approximately 2 weeks after the last visit in the administration period (ie, after the Week 16 visit or at the time of early termination), was the End of Study Visit (Visit 9).

There were 9 study visits in total, including the Screening and Follow-up Visits.

Inclusion and exclusion criteria

Key Inclusion Criteria:

• Willing to participate in the study and provide written informed consent.
• Male and female adults aged > 18 years.
• Subjects must not have participated in any diet/lifestyle intervention or observational studies, or engaged in any body weight altering regimens that resulted in body weight fluctuations (i.e. body weight loss or gain by 5%) in the preceding 3 months prior to Screening.
• A screening MRI consistent with liver inflammation and fibrosis.

Key Exclusion Criteria:

• Current or history of significant alcohol consumption.
• History or presence of liver disease (other than NAFLD/NASH).
• History or presence of cirrhosis and/or history or presence of hepatic decompensation.
• Any diabetes other than Type 2.
• Other poorly controlled medical condition (for example, uncontrolled hypertension with a systolic blood pressure > 100 mmHg).
• Known sensitivity and/or history of clinically significant food intolerance/allergies to proteins (including whey, soy, casein, amino acids, etc.).
• Unable or unwilling to adhere to contraception requirements.
• Any contraindications to a MRI scan.
• Any other condition that, in the opinion of the Investigator, renders the subject at risk for compliance, compromises the well-being of the subject, or hinders study completion.
