12. Subjects with a history of fainting from blood collections or vasovagal syncope
13. Subjects with prior exposure to P7435 or participation in any of the previous cohorts

15. Subjects with positive findings in urine drug screen
16. Subjects with a positive finding in urine alcohol screen
17. Subjects who have participated in another clinical trial within 30 days prior to the first drug administration
18. Subjects who are consuming any prescription drugs (including, but not limited to, sedatives and steroids); herbal supplements (including, but not limited to, St. John's Extract); or any other drugs likely to cause pharmacokinetic interaction within 30 days or 5 half lives, before first drug administration whichever is longer.

Arm && Interventions

Group	Intervention	Description
Placebo	Placebo	* In Part A, there will be up to 6 cohorts of 8 subjects each (for the 2 cohorts undergoing food effect study, there will be 12 subjects in each cohort). At each dose level, every subject will participate in two periods (one with active, P7435 and the second period with matching placebo or vice versa) separated by appropriate wash-out period between the two periods. The randomization scheme will ensure that no subject undergoes the placebo period twice. * In Part B, there will be up to 3 cohorts of 10 subjects each. Each of the 3 cohorts will participate in two study periods of 10 days of dosing in each (one period with active, P7435 and the other period with matching placebo or vice versa) separated by appropriate wash-out period.

Time to peak plasma concentration (t-max)	12- 14 Months	Part A: The PK profile will be derived from the P7435 plasma concentration data on Day 1.; Part B: The PK profile will be derived from the P7435 plasma concentration data on Days 1 and 10. Trough levels will be compared to assess steady state.
