ArmTypeDescription
Part A Single-ascending Dose (SAD) in Healthy ParticipantsEXPERIMENTALParticipants will be randomized into 4 + (optional) 1 dose escalating cohorts and will receive GS-4571 or placebo to match (PTM) GS-4571 on Day 1, to determine the maximum tolerated dose: * Cohort 1: Dose 1 GS-4571, administered orally as a single dose, in a fasting state. * Cohort 2: Dose 2 GS-4571, administered orally as a single dose, in a fasting state. * Cohort 3: Dose 3 GS-4571, administered orally as a single dose, in a fasting state. * Cohort 4: Dose 4 GS-4571, administered orally as a single dose, in a fasting state. * Cohort 5 (optional): Dose 5 GS-4571, administered orally as a single dose, in a fasting state.
Part B Food/PPI Effect in Healthy ParticipantsEXPERIMENTALParticipants will be randomized into 2 sequence groups in Cohort 6 and will receive the highest dose found to be safe and well tolerated in Part A of GS-4571 and omeprazole. The two sequential groups will receive the following treatments: * Treatment A: Up to the highest single dose of GS-4571 evaluated in Part A, fasting. * Treatment B: Up to the highest single dose of GS-4571 evaluated in Part A, nonfasting (high-fat/high-calorie meal). * Treatment C (optional): Omeprazole, once-daily (QD) for 5 days, fasting. * Treatment D (optional): Omeprazole followed by up to the highest single dose of GS-4571 evaluated in Part A, 2 hours later, fasting.
Part C Multiple-ascending Dose (MAD) in Nondiabetic Obese ParticipantsEXPERIMENTALParticipants randomized in Cohorts 7-9 will be randomized to receive up to 4 escalating doses of GS-4571 or PTM QD for 12 weeks, as follows: * Cohort 7: Up to dose determined from Part A of GS-4571 or PTM in obese participants, QD, in a non-fasting state * Cohort 8: Up to 3-fold the Cohort 7 dose of GS-4571 or PTM in obese participants, QD, in a non-fasting state * Cohort 9: Up to 2-fold the Cohort 8 dose of GS-4571 or PTM in obese participants, QD, in a non-fasting state * Cohort 10 is optional and will receive GS-4571 or PTM QD for 12 weeks in case it is opened for enrollment as follows: * Up to 2-fold the Cohort 9 dose of GS-4571 or PTM in obese participants, QD, in a non-fasting state.
Part D Multiple Dose in Nonobese Participants With T2DMEXPERIMENTALParticipants randomized in Cohort 11 will receive up to the highest dose of GS-4571 or PTM in T2DM, QD, in a non-fasting state for 12 weeks.
