Study information

Scientific title


Study hypothesis

Several reports have indicated that the chemokine receptor CCR5 and its ligands, especially CCL5 (formerly known as RANTES), may play a role in the pathogenesis of psoriasis. CCR5 targeted treatment could therefore be a therapeutic option for psoriasis patients.

Ethics approval

Approval received from the local ethics board (Medical Ethics Committe AMC) on the 31st March 2004 (ref: 04/44).

Study design

Randomised, placebo-controlled, parallel group, double blinded multicentre trial

Primary study design


Secondary study design

Randomised controlled trial

Trial setting

Not specified

Trial type


Patient information sheet




Subjects with moderate/severe chronic plaque psoriasis were enrolled in a randomised double-blind, placebo-controlled, parallel-group study exposed to either SCH 351125 50 mg twice daily (BID) or matched placebo, in a 2:1 ratio, for 28 days.

Intervention type



Not Specified

Drug names

SCH 351125

Primary outcome measure

1. To determine the effects of SCH 351125, a CCR5 receptor antagonist, on psoriatic plaque cellularity
2. To determine safety and tolerability of SCH 351125 in psoriatic patients

Secondary outcome measures

1. Expression of chemokine messenger RiboNucleic Acid (mRNA) within the psoriatic plaque and peripheral blood
2. Peripheral blood chemokines and CCR5 expressing cells
3. Psoriasis Area and Severity Index (PASI) and Physician Global Assessment (PGA)

Participant inclusion criteria

1. Patients 18 to 75 years of age, of either sex, and of any race
2. Patients must not be currently receiving treatment and have a diagnosis of moderate to severe psoriasis vulgaris (Psoriasis Area and Severity Index [PASI] more than eight) which must be established and must have been present for at least one year
3. The target lesion selected must be located on the trunk, arms or legs and be at least 10 cm^2 in size
4. The selected target lesion’s total numerical ratings for erythema, induration, and scaling must be at least six out of the possible nine using the following definitions for each sign: zero = none, one = mild, two = moderate, three = severe. The severity score for scaling must be at least two
5. Subjects’ clinical laboratory tests (Complete Blood Count [CBC], blood chemistries, and urinalysis) must be within normal limits or clinically acceptable to the investigator/sponsor
6. Subjects must be free of any clinically significant disease (other than psoriasis) that would interfere with the study evaluations and/or study safety
7. Subjects must be willing to give written informed consent and able to adhere to dose and visit schedules
8. Females must not be breastfeeding, and either be of non-childbearing potential (I.e., sterilised via hysterectomy or bilateral tubal ligation or at least one year postmenopausal) or if of child bearing potential, must be practicing effective contraceptive methods from at least two weeks prior to day one and until 30 days following cessation of dosing
9. Female subjects of childbearing potential must have a negative serum pregnancy test (beta-human Chorionic Gonadotropin [hCG]) at screening

4. Subjects with any pre-existing cardiovascular disease
5. Individuals who have received any vaccinations within 30 days prior to screening or a scheduled to receive a vaccination during the study
6. Subjects who are positive for hepatitis B surface antigen, hepatitis C antibodies or for Human Immunodeficiency Virus (HIV) antibodies
7. Subjects who are in a situation or have any condition that, in the opinion of the investigator, may interfere with optimal participation in the study
8. Subjects who have used any investigational drugs within 28 days of screening
9. Subjects who are not willing to follow the study restrictions or procedures
10. Individuals with any clinically significant history of food or drug allergy or allergy to any component of SCH 351125
11. Subjects who are participating in any other clinical study
