Study type
Description of intervention(s) / exposure
This is a first-in human study of ANB019. It is a double-blind, randomized, placebo controlled, ascending single (SAD) and multiple-doses (MAD) study in healthy participants with one single dose plaque psoriasis patient cohort.
The study is planned to have approximately seven cohorts in the SAD section (six for the healthy participants and one for the plaque psoriasis patients) and approximately three in the MAD section of the study (healthy participants only).
Eight (8) healthy participants will be assigned to all single and multiple dose healthy participants cohorts at predicted doses ranging from 10mg to 750mg. 15 plaque psoriasis patients will be assigned to a single dose cohort. The study drug will be administered by subcutaneous (SC) or intravenous (IV) infusion. For the MAD part and the plaque psoriasis patient cohort, the doses and administration method (SC or IV) will be determined based on the results from the healthy participant SAD part.. Participants in the single dose cohorts will be admitted to the clinical facility on Day -1 and will remain in the clinic for up to 3 days for a total of up to 4 days in-house. Dosing of ANB019 or placebo will occur on Day 1. Safety PK and PD assessments will be performed during the study.
Participants in the multiple-dose cohort(s) will be admitted to the clinical facility on Day-1 and will remain in the clinic for 3 days for a total of 4 days in-house. Following this in-house period, participants will be admitted the evening prior to their next dosing day and discharged the evening of the day of dosing for a total of 3 additional doses of ANB019 and 3 additional days in-house for a total of 7 days.
Intervention code [1] 297396 0
Treatment: Drugs
Comparator / control treatment
The placebo will be sterile normal saline (0.9% NaCl) for injection.
Control group

Primary outcome [1] 301365 0
Safety assessments of ANB019 administration will be based on medical review of adverse event reports and the results of vital sign measurements, ECGs, physical examinations, and clinical laboratory tests.

Intervention assignment
Other design features
This is an ascending dose study divided into three parts. The healthy participants SAD part, in which, depending on the safety of the drug observed on a cohort, the dose might be increased. If the safety and pharmacokinetic and pharmacodynamic parameters attain levels acceptable to the sponsor and Safety Review Team (SRT), the study will proceed to the plaque psoriasis patients part and the healthy participants multiple ascending dose (MAD) phase. As well, during the MAD part, the decision to escalated the dose will be taken by the SRT based on the safety parameters observed until that moment. The plaque psoriasis patients will be included in parallel with the healthy participants MAD cohorts.

Brief summary
This study will be conducted in three parts: the first part will investigate the effect of a single dose of ABN019 on healthy participants; the second part will investigate the effect of a single dose of ANB019 on psoriasis patients and the third part will investigate the effect of multiple (weekly) doses of ABN019 for 4 weeks on healthy participants. The single dose study will explore different doses of the study drug given either via a subcutaneous (under the skin) injection (SC) or via an intravenous (into the vein) infusion (IV). The results from this part will be used to determine the dose and route of administration to be used for the psoriasis patient part and the multiple dose part of the study.
Over the entire study a total of 87 people will be enrolled over 10 dosing groups/ cohorts. In each group of 8 healthy participants, 6 will receive the active drug, ANB019 and the other 2 will receive an equivalent placebo (an injection/ infusion that looks identical to the active drug, but contains no active drug). In the psoriasis patient group, out of the 15 patients, 10 will receive the active drug, ANB019, and the remaining 5 will receive placebo.
This study is a dose escalation study meaning that the first group/ cohort will receive the lowest dose of study drug. Results will be reviewed by a safety monitoring committee after each dose strength has been tested to make sure that it is safe to continue with the next higher dose strength in the next group. The next group will not be enrolled until the safety monitoring committee have confirmed it is safe to do so. The study can be stopped at any time, based on evaluation of the side effects of the study drug.
As this is a first in human study, the primary objective of the study is to assess the safety and tolerability of single and multiple doses of ANB019 administered to healthy humans.
