A Safety/Tolerance Phase, Ascending Single Dose Study to Evaluate the Safety and Tolerability of G3P-01, a Food-Grade Pectic Product, in Healthy Volunteers

A Safety/Tolerance Phase, Ascending Single Dose Study to Evaluate the Safety and Tolerability of G3P-01, a Food-Grade Pectic Product, in Healthy Volunteers

This is an interventional, open-label study to evaluate the safety, tolerability and PK of escalating single doses of G3P-01 in 10 healthy adult subjects. All participants will receive G3P-01 in sequential, escalating doses of 50mg (Period 1), 500mg (Period 2), 1,000mg (Period 3), and 2,000mg (Period 4). A wash out period of at least 7 days will occur between doses in each sequential treatment period. Subjects will be admitted Day 1 and stay overnight until the morning of Day 2 for each treatment period. There will be a follow up call 14 days (+/- 2 days) following the last dose of the IP.

4. Non-pregnant, non-lactating females who are either post-menopausal (natural or surgical) or are using at least one (1) of the following forms of contraception:

   • Cervical cap, diaphragm, or sponge with spermicide,

   • A combination of male condoms with either cervical cap, diaphragm, or sponge with spermicide (double-barrier methods)

   • Combined (estrogen- and progestogen-containing) hormonal contraception associated with inhibition of ovulation

     • oral
     • intravaginal
     • transdermal
     • injectable

   • Progestogen-only hormone contraception associated with inhibition of ovulation

     • oral
