Brief Summary:
The present study is designed to assess the effects of Rifampin on the pharmacokinetics of N91115 in healthy subjects.

Condition or disease Intervention/treatment Phase
Drug Interaction Potentiation Drug: N91115 Drug: Rifampin Phase 1

Detailed Description:

This study will assess the effects of multiple oral dose administration of rifampin on the steady state plasma pharmacokinetics (PK) of N91115 in healthy subjects.

Eligible subjects (n=15) will receive oral doses of N91115 twice daily (approximately every 12 hours) on Study Days 1 through the morning of Day 13. On Study Days 8 through 12, rifampin administered 600 mg once daily will be added to the N91115 regimen. Study subjects will be monitored for safety while housed in the clinical research unit (CRU) until discharge on Day 14. Pharmacokinetics will be followed from Study Day 1 through Study Day 14. A follow-up phone call will be made on Day 20 (1 day). Participation of an individual subject may last up to approximately 48 days from the time of screening until the end-of-study follow-up call.

Primary Outcome Measures :
  1. Assess the Potential Effects of Rifampin on N91115 Steady State Area Under the Curve (AUC) Values [ Time Frame: On Study Day 14 ]
    To assess the effects of multiple oral dose administration of rifampin on the steady state AUC on Day 14 of N91115 in healthy subjects.


Secondary Outcome Measures :
  1. Effects of Rifampin on the AUC vs time of Metabolites of N91115 [ Time Frame: On Study Day 14 ]
    make a preliminary non statistical assessment on the effects of multiple oral dose administration of rifampin on steady state plasma PK of N91288 and metabolites, in healthy subjects

  2. The number of participants with adverse events [ Time Frame: Over the 21 days of the study ]
    To evaluate the safety and tolerability of multiple oral doses of N91115 in the presence and absence of multiple oral doses of rifampin

  3. Effects of Rifampin on N91115 and its Metabolites on Urine 12 Hour drug concentrations [ Time Frame: Day 14 assessment ]
    To make a preliminary non statistical assessment on the effects of multiple oral dose administration of rifampin on the 12 hour steady state urine PK of N91115 and its primary metabolites in healthy subjects
