Outcome Measures

Primary Outcomes (2)

  • Safety and tolerability of 2 and 15 day repeat consumption of Hoodia gordonii Purified Extract (H.g.PE)

    Safety and tolerability (Adverse Events (AEs), vitals signs, Electrocardiogram (ECG), laboratory assessments) of twice daily consumption of 1110 mg of formulated Hoodia gordonii purified extract (H.g.PE) consumed over a period of 2 or 15 days were assessed up to 41 days after start of the intervention

    41 days

  • Efficacy of 15-day repeat consumption of H.g.PE

    Efficacy of twice daily consumption of 1110 mg of formulated H.g.PE during 15-day repeat intake was assessed. Appetite scores, ad libitum energy intake, body weight and body composition were assessed during the 15-day intervention.

    15 days

Secondary Outcomes (1)

  • Assessment of the pharmacokinetics of PYM50057 a marker of the steroid glycosides in H.g.PE

    41 days
