E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
• Evaluate the efficacy of oral piclidenoson 2 mg or 3 mg twice daily (BID) in patients with moderate-to-severe plaque psoriasis, compared with placebo, as determined by the proportion of subjects who achieve a Psoriasis Area and Severity Index (PASI) score response of ≥75% (PASI 75) at Week 16 (superiority); and • Evaluate the safety of oral piclidenoson in this patient population. |
|
E.2.2 | Secondary objectives of the trial |
• Evaluate the efficacy of oral piclidenoson 2 mg or 3 mg BID, compared with placebo, as determined by the proportion of subjects who achieve, respectively, PASI 50, Physician Global Assessment (PGA) score of 0 or 1, and improvement on the Psoriasis Disability Index (PDI) at Week 16 (superiority) • Evaluate the efficacy of oral piclidenoson 2 mg or 3 mg BID, compared with apremilast, as determined by the proportion of subjects who achieve PASI 75, PGA score of 0 or 1, PASI 50 (non-inferiority), and improvement in PDI at Weeks 16 and 32; • Establish assay sensitivity within this trial by comparing the efficacy of apremilast 30 mg BID with that of placebo tablets BID, as determined by the proportion of subjects who achieve PASI 75, PGA score of 0 or 1, PASI 50, and improvement in PDI at Week 16(superiority); • Evaluate the efficacy and safety data for piclidenoson through the Extension Period of up to 48 weeks of treatment;

E.3 | Principal inclusion criteria |
1. Male or female, 18 to 80 years of age, inclusive; 2. Diagnosis of moderate-to-severe chronic plaque-type psoriasis with BSA involvement ≥10%, as judged by the Investigator; 3. PASI score ≥12 (Appendix 3); 4. Static PGA ≥3 (Appendix 2); 5. Candidate for systemic treatment or phototherapy for psoriasis; 6. Duration of psoriasis of at least 6 months; 7. Females of childbearing potential must have a negative serum pregnancy test at screening; 8. Female subjects of childbearing potential must use highly effective contraception throughout the course of the trial and for 3 months after. Highly effective methods include hormonal contraception (e.g., combined oral contraceptives, patch, vaginal ring, injectables, and implants; each method must be used with a barrier method, preferably male condom), intrauterine device or system, tubal ligation, partner vasectomy, or dual (male plus female) barrier methods (each barrier method must be used with a hormonal method). Female subjects who use a hormonally based method must agree to use it in conjunction with a barrier method. Female partners of male study subjects should consider using one of the above methods of contraception as well. Post-menopausal status is defined as menopause for at least 1 year prior to the Screening Visit and must be confirmed by an elevated serum FSH level. 9. Male subjects must refrain from sperm donation during treatment and until at least 90 days after the end of study drug dosing. Male subjects with fertile or pregnant partners must agree to use condoms throughout the course of the trial and for 3 months after. 10. Ability to complete the study in compliance with the protocol; and 11. Ability to understand and provide written informed consent. |

E.4 | Principal exclusion criteria |
1. Psoriasis limited to erythrodermic, guttate, palmar, plantar, or generalized pustular psoriasis in the absence of plaque psoriasis; 2. Prior treatment with apremilast within 4 weeks prior to the Baseline visit, or contraindication to apremilast; 3. Treatment with systemic retinoids, corticosteroids, tofacitinib, or immunosuppressive agents (e.g., methotrexate, cyclosporine) within 4 weeks of the Baseline visit; 4. Treatment with a biological agent (etanercept, adalimumab, efalizumab, infliximab, ustekinumab, alefacept, secukinumab, or others, including investigational agents) within a period of time equal to 5 times its circulating half-life, or 30 days, whichever is longer, prior to the Baseline visit; 5. Treatment with high potency topical dermatological corticosteroids (Class I-III in US, Class III-IV in Europe), Vitamin D analogs, keratolytics, or coal tar (other than on the scalp, palms, groin, and/or soles) within 2 weeks of the Baseline visit; 6. Ultraviolet or Dead Sea therapy within 4 weeks of the Baseline visit, or anticipated need for either of these therapies during the study period; 7. Treatment with lithium, hydroxychloroquine or chloroquine within 2 weeks of the Baseline visit, or anticipated need for such drugs during the study period, unless dose has been stable for 3 months prior to the Screening visit and will remain stable throughout the trial; 8. Serum creatinine level greater than 1.25 times the laboratory’s upper limit of normal atScreening; 9. Liver aminotransferase levels greater than 1.5 times the laboratory’s upper limit of normal at Screening; 10. QTcF interval on Screening Visit ECG or on average of triplicate Baseline Visit ECGs >450 milliseconds (msec) for males or > 470 msec for females (except when QT prolongation is associated with right or left bundle branch block, in which case enrollment is allowed); 11. A condition which increases proarrhythmic risk, including hypokalemia, hypomagnesemia, or congenital Long QT Syndrome; 12. Heart disease which is, in the Investigator’s judgment, clinically unstable; 13. Ongoing or planned use of a concomitant medication that is on the CredibleMedsTM list of drugs known to cause Torsades des Pointes (Appendix 7); 14. Active gastrointestinal disease which could interfere with the absorption of oral medication; 15. Pregnancy, planned pregnancy, lactation, or inadequate contraception as judged by the Investigator; 16. Active drug or alcohol dependence; 17. History of depression or suicidal ideation within the past year; 18. Concomitant use of strong cytochrome P450 inducers, e.g., rifampin, phenobarbital, phenytoin, carbamazepine; 19. Previous participation in a piclidenoson (CF101) clinical trial; 20. Significant acute or chronic medical or psychiatric illness that, in the judgment of the Investigator, could compromise subject safety, limit the subject’s ability to complete the study, and/or compromise the objectives of the study; 21. Participation in another investigational drug or vaccine trial concurrently or within 30 days prior to the Screening visit. |
