Description of intervention(s) / exposure
Three parts:

Part A: Multiple Cohorts, Single Ascending Dose

Part B: Multiple Cohorts, Multiple Ascending Dose, dose TBD based on the safety data from Part A by a safety review committee

Part C: Multiple Cohorts of Asian Healthy Volunteers, Single Ascending Dose, dose TBD based on the safety data from Part A by a safety review committee.



Each Part will involve unique participant cohorts



Mode of Administration – subcutaneous (SC) injection or intravenous (IV) infusion. Participants must fast overnight for at least 8 hours for pre-dose safety labs prior to each dose.

All interventions will be administered only in the Phase 1 unit, and adherence will be monitored by supervised administration by site staff.

Cohort 6: ABBV-CLS-628 single dose on Day 1 – up to 900mg IV infusion

Cohort 6b: ABBV-CLS-628 single dose on Day 1 - Optional mg SC injection

Each Part A Cohort will include 2 sentinel participants (1 ABBV-CLS-628, 1 placebo) who will be dosed first prior to dosing the rest of the Cohort.

Outcomes
Primary outcome [1] 333334 0
To evaluate the safety and tolerability of escalating single and multiple doses of ABBV-CLS-628 following single and multiple IV infusions or SC injections



Adverse events will be assessed and documented in accordance with the NIH DAIDS grading scale. Possible AEs:



Decreases in the blood cells responsible for carrying oxygen from the lungs to other parts of the body and for protecting the body from infection will be assessed by standard blood chemistry.

Increase in a substance in the blood that helps it to form clots will be assessed by standard blood chemistry.

Pain, redness or swelling around the point of injection will be assessed by visual inspection.
