Description of intervention(s) / exposure
The study consists of 2 Parts: Part A & Part B

Part A is open-label where subjects with CPP will receive a single topical treatment with ZL-1102 to a suitable psoriatic plaque followed by a 1-week observation period for safety/tolerability.
Subjects who are eligible for the study will report to study sites on Day 1 for baseline evaluations.
There will be pre-dose PK sampling and intensive PK sampling for 24 hours post-dose. After completion of the safety evaluation in Part A, and in the absence of findings that would trigger stop criteria, enrollment of subjects for Part B will be started
the dose of ZL-1102 administered: 2.3g/tube, recommended dosage to target plaque is approximately 0.15mg~0.3mg /cm2 [ZL-1102, 1% (w/w) Gel. Topical application should be based on the initial size of target plaque.

Part B
Part B is a double-blind, two-arm comparison of ZL-1102 Gel vs. Vehicle (placebo only). Approximately 44 subjects with CPP will be randomized in a 1:1 ratio to receive study medication of ZL-1102 Gel or Vehicle.

Part B will consist of a screening period, (Day -30 till Day -1), a 4-week treatment period during which study drug will be applied topically to a suitable psoriatic plaque, and a 2- week follow-up period.
study treatment: twice daily (BID)
the dose of ZL-1102 administered: 2.3g/tube, recommended dosage to target plaque is approximately 0.15mg~0.3mg /cm2 [ZL-1102, 1% (w/w) Gel. Topical application should be based on the initial size of target plaque.

The overall study duration is approximately 6 months (4.5 months recruitment plus 1.5 months study observation period).

Route of Administration is Topical
Dosage Formulation: gel
clinician or research nurse administers the gel.
adherence or fidelity will be assessed: in Part B, only the 1 tube each time study drug applied in clinic at D1, D8, D15 and D22. The weights should be recorded to the nearest 0.01gat minimum. And the subjects are trained to apply study drug as clinician or research nurse do, and record it in the patient diary.

frequency of administration in Part B: Study drug (ZL-1102 or matching placebo) will be applied twice daily for 28 days. No participants in Part A can participate in Part B.
