Brief Summary:
The study is being conducted to investigate the effect of itraconazole treatment in the pharmacokinetics of RG1662. It is also to evaluate the exposure of RG1662 vs. QTc response relationship and the safety and tolerability of RG1662 when given in combination with itraconazole in healthy subjects.

Arm Intervention/treatment
Experimental: Combination therapy RG1662 + itraconazole
Days 20-29: Oral administration RG1662 twice daily within 30 minutes of a meal + 2 x 100 mg itraconazole once daily with food
Drug: RG1662
Drug: itraconazole
Experimental: RG1662 Monotherapy
Days 1-10: RG1662 120 mg twice daily (b.i.d.) within 30 minutes of a meal for 10 days (Days 1 to 9, Day 10 only a.m. dose). (Cohort A subjects will receive 1 x 120 mg RG1662 tablets twice daily. In Cohorts B and C the dose of RG1662 will be decided upon following review of the interim safety and pharmacokinetic data of the 4 subjects in Cohort A.)
Drug: RG1662
Experimental: itraconazole Monotherapy
Days 15-19: 200 mg of itraconazole twice daily for 5 days (Days 15 to 18, Day 19 only a.m. dose)
Drug: itraconazole

Primary Outcome Measures :
  1. Area under the plasma concentration-time curve from 0-t (AUC0-t) [ Time Frame: Within 29 days ]
  2. Maximum observed plasma concentration (Cmax) [ Time Frame: Within 29 days ]
  3. Time to maximum observed plasma concentration (Tmax) [ Time Frame: Within 29 days ]

Secondary Outcome Measures :
  1. Change from baseline in QTcF [ Time Frame: Up to 29 days ]
  2. Incidence of adverse events [ Time Frame: Within 43 days ]
  3. Clinically significant changes from baseline in physical examination or laboratory parameters [ Time Frame: Within 29 days ]
  4. Mean model parameters of RG1662 concentration vs. QTcF changes [ Time Frame: Within 29 days ]
