Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to identifying the intramuscular dose equivalent to the 4mg intravenous dose and assess its safety and tolerability as a weekly injection.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The purpose of this bridging study is to advance the therapeutic development of Allopregnanolone (Allo) by using the intramuscular (IM) route of administration as an alternative to the intravenous (IV) route. In order to identify the equivalent IM dose we will conduct pharmacokinetic (PK) analysis previously informed by simulations and modeling. We will recruit a total of 12 participants, both males and females equally distributed, into this single-arm, open-label study.

PK analysis and dose finding will take place for the initial 4 weeks; some participants may not require all 4 weeks of initial dosing to establish maintenance dose. Once maintenance dose is established all participants will receive weekly administration of Allo IM until they complete 12 weeks total of Allo exposure (5 or 6 clinic visits and 6 or 7 home-nurse visits).
