Description of intervention(s) / exposure
NVG-291 is a drug injected under the skin (subcutaneous). The trial is split into three parts, starting with Part 1 (SAD), then Part 2 (MAD - post-menopausal Females), and finally Part 3 (MAD - males and premenopausal females). In Part 1 (SAD), participants received 1 dose on 1 day only. Doses began with 0.032 mg/kg (Cohort 1) and increased until 0.864 mg/kg (Cohort 6). Each cohort began after a safety review committee reviewed the data from the previous cohort. An additional cohort was enrolled at the end of Part 1, to be dosed at 0.864 mg/kg, to assess CSF drug levels.
In Part 2 (MAD), postmenopausal female participants received 1 dose daily for for 14 consecutive days. The starting dose for Part 2 was 0.384 mg/kg (2 dose levels lower than the maximum dose achieved during Part 1). There were 3 cohorts in Part 2. The maximum daily dose in Part 2 did not exceed the maximum daily dose tolerated in Part 1.
In Part 3 (MAD), male and pre-menopausal female participants will received 0.547 mg/kg daily for for 14 consecutive days.
All study parts will be monitored by a qualified CRA to assure study procedures and dose administrations are performed as per protocol.

Treatment: Drugs
Comparator / control treatment
Salt water is being used as a placebo and will be injected under the skin (subcutaneous). In Part 1 (SAD), participants receive 1 dose on 1 day only and in Parts 2 and 3 (MAD), participants receive 1 dose every day for 14 days. Doses will start low and increase for every cohort in Parts 1 and 2. All participants in Part 3 will receive the same daily dose.
Control group
Placebo
