The aim of the present Phase III study is to evaluate the safety, efficacy and pharmacokinetics of Caffeine Citrate for treatment of apnea of prematurity in Japan.
Apnea of Prematurity
Drug: NPC-11 for intravenous or oral administration.
||Endpoint Classification: Safety/Efficacy Study
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
||A Phase III Clinical Study of NPC-11 in the Treatment of Apnea of Prematurity. - Investigation of Safety, Efficacy and Pharmacokinetics of Caffeine Citrate -
Primary Outcome Measures:
- Success rates for controlling of apnea episode in each observation day (at least 50% reduction of apnea episodes from baseline) [ Time Frame: 1, 2, 3, 4, 5, 6,7, 8, 9 and 10 day ] [ Designated as safety issue: No ]
Secondary Outcome Measures:
- The change of frequency of apnea episode from baseline in each observation day [ Time Frame: 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10 day ] [ Designated as safety issue: No ]
- Time to event：Days until next events occurred [ Time Frame: 1 to 10 day ] [ Designated as safety issue: No ]
Time to event：Days until next events occurred.
The definition of events are, Not at least 50% reduction of apnea episode Not improving the frequency of episode from baseline Needs mechanical/bag valve mask ventilation.
- The change of average duration time of apnea episode from baseline in each observation day [ Time Frame: 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10 day ] [ Designated as safety issue: No ]
- The change of lowest oxygen saturation during apnea episodes from baseline in each observation day [ Time Frame: 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10 day ] [ Designated as safety issue: No ]
- The proportion of less than 85% oxygen saturation during apnea episodes in each observation day [ Time Frame: 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10 day ] [ Designated as safety issue: No ]

- Loading Dose (Day 1): Caffeine citrate 20 mg/kg body weight will be administered intravenously using a syringe infusion pump over 30 minutes.
- Maintenance Dose (Day 2～Day 10): After an interval 24 hours, caffeine citrate 5 mg/kg body weight will be administered intravenously (over 10 minutes) or orally if the patients will be able to receive oral administration once a day. The maintenance dose can be increased to a maximum 10 mg/kg caffeine citrate once a day if apnea persists.
Drug: NPC-11 for intravenous or oral administration.
NPC-11, Each vial (3mL) contains 60 mg caffeine citrate (equivalent to 30mg caffeine).
Other Name: caffeine citrate
