A Phase 1, Randomized, 3-Part Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of Single and Multiple Ascending Doses of CC-92252 in Healthy Adult Subjects and Adult Subjects With Psoriasis.
A Phase 1, Randomized, 3-Part Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of Single and Multiple Ascending Doses of CC-92252 in Healthy Adult Subjects and Adult Subjects With Psoriasis.
This is a phase 1, randomized, single-center, 3-part, study to assess the safety, tolerability, PK, and PD, of single and multiple doses of CC-92252 in healthy adult subjects and multiple doses of CC-92252 in adult subjects with psoriasis.
Inclusion Criteria:
Subjects must satisfy the following criteria to be enrolled in the study:
Part 1, Part 2, and Part 3
Subject is ≥ 18 and ≤ 55 years (Part 1 and Part 2) and age is ≥ 18 and ≤ 60 years (Part 3) of age at the time of signing the ICF.
Subject has provided informed consent prior to initiation of any study specific activities/procedures
Subject has a body mass index (BMI) ≥ 18 and ≤ 30 kg/m2 (Part 1 and Part 2) and BMI ≥ 18 and ≤ 33 kg/m2 (Part 3), at screening.
Subject has clinical laboratory safety test results that are within normal limits or considered not clinically significant by the Investigator.
Applicable to Part 3 only
Subject has a clinical diagnosis of stable plaque-type PsO at least 6 months prior to screening, defined as:
BSA ≥ 5% (at both screening and baseline), and sPGA score ≥ 3 (at both screening and baseline)

Part 1 and Part 2 only: Subject has used any non-prescribed systemic or topical medication within 14 days prior to the first dose administration. Exceptions may apply on a case-by-case basis if considered not to interfere with the study objectives as agreed to and documented by the Investigator and Sponsor's Medical Monitor.

Vaccination within 30 days prior to the first dose administration or subject has plans to receive a vaccination during the course of the study
Subject has received immunization with a live or live attenuated vaccine within 2 months prior to the first dose administration or is planning to receive immunization with a live or live attenuated vaccine for 2 months following the last dose administration
Subject has a positive QuantiFERON®-TB Gold (or equivalent) TB test at screening or 2 successive indeterminate QuantiFERON®-TB Gold (or equivalent) TB tests at screening

Subjects must not use these treatments within 24 hours prior to each clinic visit.
