• Treatment with a monoclonal antibody or other biologic agent for psoriasis within 8 weeks for etanercept, adalimumab, or infliximab, or within 12 weeks for all other agents, prior to the Baseline visit;

• Ultraviolet or Dead Sea therapy within 4 weeks of the Baseline visit, or anticipated need for either of these therapies during the study period;
• 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;
• Ongoing or planned use of a concomitant medication that is on the CredibleMedsTM list of drugs known to cause Torsades des Pointes;
• Active drug or alcohol dependence;
• Concomitant use of strong cytochrome P450 inducers, e.g., rifampin, phenobarbital, phenytoin, carbamazepine;
• Previous participation in a piclidenoson (CF101) clinical trial;
• Participation in another investigational drug or vaccine trial concurrently or within 30 days prior to the Screening visit.

Más betegség

• Active gastrointestinal disease which could interfere with the absorption of oral medication;
• Any significant/uncontrolled neuropsychiatric illness judged as clinically significant by the investigator during screening or at Day 1, or any lifetime history of suicidal ideation, suicidal behavior, or suicidal attempts by medical history or by Columbia Suicide Severity Rating Scale (C-SSRS) documentation, or by answering "yes" to Question 4 or 5 for suicidal ideation on the C-SSRS at screening or at Day 1, or is clinically deemed to have a suicide risk by the investigator;
• 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; and

Laborértékek

• Liver aminotransferase levels greater than 1.5 times the laboratory's upper limit of normal at Screening;
• QTcF interval \> 450 milliseconds (msec) for males or \> 470 msec for females on Screening Visit and Baseline visit ECGs (average of triplicate ECGs at each visit) (except when QT prolongation is associated with right or left bundle branch block or cardiac pacemaker, in which case enrollment is allowed);
• A condition which increases proarrhythmic risk, including hypokalemia, hypomagnesemia, or congenital Long QT Syndrome;
