To assess the pharmacokinetics of 3 doses and the food effect of a single high dose of BBI-5000 capsules in healthy adult subjects.

This is an open-label, randomized, 4-period, 4-way crossover, 4-sequence study to evaluate the pharmacokinetics (PK) and food effect of BBI-5000 capsules in healthy adult subjects.

Participating subjects will receive a single oral dose of BBI-5000 followed by a washout period of 7-14 days between doses. The treatment period will be followed by 5-10 day follow-up period.

PK and PD will be assessed by blood sampling through 72 hours postdose.

Safety will be assessed through collection of vital signs, adverse events, physical examination, ECGs and clinical laboratory tests.
