简要总结
Phase I study aiming at:
- assessing the absolute bioavailability, pharmacokinetic profile, and dose proportionality of interferon beta-1a (HSA-free solution in pre-filled syringes) after i.v. and s.c. administration as well as the pharmacodynamic profile to create the link with available surrogate markers investigated with both formulations used clinically, lyophilisate with HSA (HSA+) and solution without HSA (HSA-);
- gathering further information on safety and tolerability of interferon beta-1a over dose range,including local and systemic tolerance, body temperature, vital signs, and a battery of exploratory sickness behavior tests.

- •Dark skin preventing local tolerance assessment or abnormal cutaneous reaction e.g. urticaria or papular dermographism
- •Intense sport activities.
- •Any clinically significant laboratory value on screening that were not within normal range on single repeat
- •Positive hepatitis B & C antigen screen
- •Positive HIV antibody screen or screen not performed
- •Any recent acute illness or sequelae thereof which could expose the subject to a higher risk or might confound the results of the study
- •Treatment in the previous three months with any drug known to have well-defined potential for toxicity to a major organ
- •History of hypersensitivity to any drug if considered as serious
- •History of alcohol or drug abuse
- •Positive qualitative urine drug test at screening
- •Use of any medication in 2 weeks prior to study and throughout study, including aspirin or other over-the-counter preparation.
- •Blood (500 mL) donation or hemorrhage during the previous three months
- •Participation in a clinical trial in the previous 3 months

- •Present consumption of a large quantity of alcohol or wine or equivalent
- •Psychological status which could have had an impact on subject's ability to give informed consent or behavioral tests
- •Any feature of subject's medical history or present condition which, in the investigator's opinion, could confound the results of the study, complicate its interpretation, or represent a potential risk for the subject
研究组 & 干预措施
0.5 MIU i.v. and 1.5 MIU s.c.
All 12 subjects participated in 4 periods, receiving 4 different doses of interferon beta-1a from 2 of the 4 possible pairs of treatments.
The number of treatment sequences was limited to 6 and the subjects were randomized among the 6 sequences, as one male and one female per sequence. Thus 6 subjects received each dose. The washout period between two injections (Day 1 of subsequent periods) was of 7 days or more.

结局指标
主要结局
Composite of interferon beta-1a PK parameters
时间窗: 0, 0.25, 0.5, 0.75, 1, 2, 4, 6, 8, 10, 12, 24, 48, 72 [hours post-dose]
Area under the concentration-time curve from time zero (pre-dose) extrapolated to infinite time (AUC\[0-inf\]) and maximum observed concentration (Cmax) following single dose administration will be assessed. Mean residence time (MRT), half-life of elimination (t1/2), clearance (CL), and volume of distribution at steady-state (Vss) will be calculated.
Composite of interferon beta-1a PD markers
时间窗: 0, 6, 12, 24, 48, 72, 96, 120, 168 [hours post-dose]
Serum concentration of three surrogate markers (neopterin and beta2-microglobulin and 2',5' OAS) will be measured
次要结局

- Composite of local reactions as a measure of local tolerance(0, 0.5, 1, 2, 4, 6, 8, 10, 12, 24 [hours post-dose] and then daily if needed until Day 5 or longer until resolution in case of local reaction)
- Composite of clinical laboratory tests as a measure of safety and tolerability(Screening and 0, 24 [hours post-dose])
- Composite of vital signs as a measure of safety and tolerability(Screening and 0, 1, 2, 4, 6, 8, 10, 12, 24 [hours post-dose])
