Treatment and study plan

THIAA

Dietary Supplement

A tablet containing 400 mg tetrahydro iso-alpha acids, 3 times a day

Placebo

Dietary Supplement

Placebo tablet

Primary outcomes

  1. Weight loss maintenance

    Time frame: Baseline, 64 weeks

    The primary endpoint is the absolute pounds of weight change from baseline to the end of the 64 weeks.

Secondary outcomes

  1. Weight loss

    Time frame: Baseline, 12 weeks

    Percent weight loss at the end of 12 weeks (i.e. the Stage 1 of the trial where subjects participate in HP2).

  2. Weight loss

    Time frame: Baseline, 12 weeks

    Absolute amount of weight loss at the end of 12 weeks (i.e. the Stage 1 of the trial where subjects participate in HP2).

  3. Short-term THIAA effect

    Time frame: Baseline, 12 weeks

    Comparing the difference in absolute amount of weight loss between 2 arms at the end of 12 weeks (i.e. the Stage 1 of the trial).

  4. Short-term THIAA effect

    Time frame: Baseline, 12 weeks

    Comparing the difference in percent weight loss between 2 arms at the end of 12 weeks (i.e. the Stage 1 of the trial).

  5. Weight loss

    Time frame: 12 weeks, 64 weeks

    To evaluate absolute amount of weight loss during Stage 2 of the trial where subjects participate in MLGL (i.e. 12 weeks to 64 weeks).

  6. Weight loss

    Time frame: 12 weeks, 64 weeks

    To evaluate percent weight loss during Stage 2 of the trial where subjects participate in MLGL (i.e. 12 weeks to 64 weeks).

  7. Long-term THIAA effect

    Time frame: baseline, 64 weeks

    To evaluate the difference between 2 arms the amount of weight loss during the trial (i.e. baseline to 64 weeks).
