简要总结
The purpose of this study was to investigate how vamorolone affects the CYP3A4 enzyme in humans by measuring the pharmacokinetics of midazolam and its metabolite, 1'-hydroxymidazolam, in healthy subjects. The pharmacokinetics of midazolam were measured on Day 1 and then on Day 14 to investigate the potential interaction between the two compounds.
The safety and the tolerability was also investigated.
详细描述
This was a non-randomized, single-center, open-label, single-sequence, single-arm Phase I study.
- Day 1: Participants received a single dose of 2.5 mg midazolam in fasted state in the morning.
- Day 2: Wash-out period.
- Days 3 to 13: Participants received daily doses of 6 mg/kg vamorolone in the morning within 30 minutes after start of a standard breakfast.
- Day 14: Participants received single doses of 2.5 mg midazolam and 6 mg/kg vamorolone in fasted state in the morning.
- Safety and tolerability parameters were collected during the entire study phase from screening to follow-up.
- Blood samples for PK assessment of midazolam and 1'-hydroxymidazolam were collected from predose through 10 hours following the midazolam doses on Days 1 and 14.
- Blood samples for PK assessment of vamorolone were collected throughout the vamorolone dosing period.
- Blood and urine biomarkers samples for CYP3A4 induction assessment were collected throughout the treatment period.
- On Day 28, a follow-up safety phone call was done

- •Body weight ≥ 50 kg and a BMI ≥ 18 kg/m2 and ≤ 29.9 kg/m2 at screening.
- •Male and female. Contraceptive use by men and women should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies.
- •Male subjects:
- •If the subject is a sexually active man and not surgically sterilized, he must be willing to:
- •Abstain from sexual intercourse or
- •Use a condom plus another form of contraception, (e.g., spermicide, IUD, birth control pills taken by female partner) if engaging in sexual intercourse with a woman who could become pregnant.
- •Use a condom during sexual intercourse with pregnant or lactating women.
- •Must not father a child and must refrain from donating sperm from administration of the first dose and up to 3 months after the last dose of study treatment.
- •Female subjects:
- •All women (regardless of their status, i.e. WOCBP and WONCBP; for definitions see Section 10.4.1) must have a negative serum β-hCG pregnancy test prior to the initiation of the study treatments. FSH levels of suspected postmenopausal females must be > 30 mIU/mL.
- •Vamorolone has the potential to induce CYP3A4, which may result in a reduction in the effectiveness of contraceptives that are metabolized by CYP3A4 such as hormonal contraceptives when co-administered with vamorolone. Therefore, hormonal contraceptives by any route of administration are contraindicated.
- •Women participating in the study must be either:
- •WONCBP or
- •WOCBP using, during the length of the study and for at least 3 months after the stop of the study treatments, 1 of the following contraceptive methods plus a condom:

- •Any IUD with published data showing that the lowest expected failure rate is less than 1% per year (not all IUDs meet this criteria)
- •Any other methods with published data showing that the lowest expected failure rate for birth control is less than 1% per year, or
- •Abstinent from intercourse for 2 weeks before exposure to the study treatments, throughout the clinical trial until 3 months following discontinuation of the study treatments, or
- •Have a male partner who is sterile prior to the woman's entry into the study and is the sole sexual partner for that woman during the study period.
- •The Investigator is responsible for review of medical history, menstrual history, and recent sexual activity to decrease the risk for inclusion of a woman with an early undetected pregnancy.
- •Subject is a non-smoker for at least 3 months prior exposure to the study treatments. Subject must also have abstained from use of other nicotine containing products (e.g., nicotine patch, chewing gum or e-cigarettes) for at least 3 months before exposure to the study treatments.
- •Capable of giving signed informed consent as described in Section 10.1, which includes compliance with the requirements and restrictions listed in the ICF and in this protocol prior to any clinical study specific procedure.
- •Supine systolic blood pressure ≥ 90 mmHg and ≤ 140 mmHg; diastolic blood pressure ≥ 50 mmHg and ≤ 90 mmHg and pulse rate ≥ 45 bpm and ≤ 90 bpm, and tympanic body temperature ≥ 35.0 °C and ≤ 37.5 °C at screening.
