Brief summary

The primary purpose of the study is to evaluate the safety and tolerability of escalating doses of KER-065 administered as single and multiple subcutaneous doses in healthy adult volunteers.

Interventions

IP Name: KER-065 Treatment Drug - KER-065 Treatment Drug - Placebo There are 2 parts (Part 1 and Part 2) in this study. Single Ascending Dose (SAD) Cohorts - Part 1 SAD 1 - Participants will receive 1mg per kg of single dose of subcutaneous KER-065 or placebo on Day 1 SAD 2- Participants will receive 3mg per kg of single dose of subcutaneous KER-065 or placebo on Day 1 SAD 3 - Participants will receive 5mg per kg of single dose of subcutaneous KER-065 or placebo on Day 1 Multiple Ascending D

IP Name: KER-065 Treatment Drug - KER-065 Treatment Drug - Placebo There are 2 parts (Part 1 and Part 2) in this study. Single Ascending Dose (SAD) Cohorts - Part 1 SAD 1 - Participants will receive 1mg per kg of single dose of subcutaneous KER-065 or placebo on Day 1 SAD 2- Participants will receive 3mg per kg of single dose of subcutaneous KER-065 or placebo on Day 1 SAD 3 - Participants will receive 5mg per kg of single dose of subcutaneous KER-065 or placebo on Day 1 Multiple Ascending Dose (MAD) Cohorts - Part 2 MAD 1 - Participants will receive 2mg per kg subcutaneous KER -065 or placebo on Days 1, 29 and 57. MAD 2 - Participants will receive subcutaneous KER -065 or placebo on Days 1, 29 and 57. Study drug will be administered as a SC injection by trained personnel at the study site. Initial MAD 1 dose level is 2mg/kg based on the review by the safety review committee (SRC) of SAD 1 and SAD2 safety and available PK data. MAD 2 dose is based on the review by SRC of MAD 1 safety and available PK data. In SAD 1-3 the ratio is 4:2, in MAD 1 the ratio is 6:2 and MAD 2 the ratio is 8:4. Participants are dosed whilst in confinement only and participants in MAD cohorts will be contacted and reminded of their readmission dates for their second and third doses.
