Arm Intervention/treatment
Experimental: Standard Percentage Drug: Pantoprazole
40 mg delayed‑release tablet administered orally in the morning of Days 1-7
Drug: SCH 530348 (standard percentage)
2.5 mg tablet containing ~23% API as free base (STANDARD) administered orally on the morning of Day 5
Experimental: High Percentage Drug: Pantoprazole
40 mg delayed‑release tablet administered orally in the morning of Days 1-7
Drug: SCH 530348 (high percentage)
2.5 mg tablet containing ~46% active pharmaceutical ingredient (API) as free base (46+5%) administered orally on the morning of Day 5

Primary Outcome Measures :
  1. Area under the plasma concentration-time curve from 0 to 72 hours (AUC[0-72h]) of SCH 530348 [ Time Frame: Up to 72 hours after SCH 530348 dose on Day 5 ]
  2. Maximal plasma concentration (Cmax) of SCH 530348 [ Time Frame: Up to 72 hours after SCH 530348 dose on Day 5 ]

Secondary Outcome Measures :
  1. Number of participants experiencing clinical and laboratory adverse events (AEs) [ Time Frame: Up to 2 weeks after last dose ]
