Brief Summary

This is a phase 1 randomized double blind, first in human (FIH) study with the novel oral Alzheimer drug candidate REM0046127, which consists of two main parts, a single ascending dose (SAD) study with 7 cohorts followed by a multiple ascending dose (MAD) study with 2 cohorts.

Detailed Description

SAD

As a baseline, 5 cohorts of 8 young healthy males are foreseen, with a repeat to assess food impact and an additional elderly cohort. Depending on the early FIH findings, the number of cohorts could be more or less. FIH studies include initially only males due to the incomplete nature of preclinical reproductive toxicology studies

• Treatment duration: single day
• Each cohort:

• 2 volunteers on placebos, of which 1 sentinel
• 6 volunteers on study drug, of which 1 sentinel
• Timing for each cohort will be about 21 days

• Subjects will be screened for selection from day -21 to day -1 before starting the experimental phase of each cohort
• First the 2 sentinels will be dosed
• Following the review of sentinel safety and tolerability data through the Data Safety Monitoring Board (DSMB) after one day or 2 half-life times following the sentinel dosing, the remaining 1+5 subjects will be randomized and dosed approximately 7 days after the sentinels

MAD

• First cohort of 10 healthy young male subjects. This cohort can be initiated after the food interaction has been assessed in the last safe SAD cohort, and does not need to wait for the elderly cohort.
• Second cohort of 12 healthy elderly subjects:

• The 1st cohort of healthy young male at about 75% of the Maximum Tolerated Dose (MTD) of the SAD
• The 2nd cohort of healthy older male and female (not of child-bearing potential) at about 50 or 100% of the highest tolerable dose of the SAD, depending on the observations in the 1st MAD cohort to assess potential impact of age on Pharmacokinetics (PK)
• Treatment duration: 7 days
• Timing for each cohort will be about 35 days
• Subjects will be screened for selection from day -21 to day -1 before starting the experimental phase each cohort
• First the sentinels will be dosed
• Following the review of sentinel safety and tolerability data through the DSMB, the remaining subjects will be randomized and dosed approximately 14 days later
• According to plan the sentinels of the 2nd cohort will be dosed about 35 days after the sentinels of the 1st cohort.

Study Groups

Study Drug

Each subject receives either a single dose (SAD) or a multiple dose (MAD) of REM0046127 as oral solution with a concentration of 100 mg/mL REM0046127. The starting dose for the first cohort in the SAD is 35mg up to a maximum of 2000mg at cohort 5. The starting dose for the MAD study is 0,75 of the Maximum Tolerated Dose (MTD) from the SAD.
