Accepts Healthy Volunteers
Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.
An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.
Searching Both is inclusive of interventional and observational studies.

Elevated whole blood A3AR expression level, defined as ≥ 1.5-fold over a predetermined normal population standard at Screening; 8. Females of child-bearing potential must have a negative serum pregnancy test at screening; 9. Females of child-bearing potential must be willing to use 2 methods of contraception deemed adequate by the Investigator (for example, oral contraceptive pills plus a barrier method) to be eligible for, and continue participation in, the study; 10. Ability to complete the study in compliance with the protocol; and. 11. Ability to understand and provide written informed consent.
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 1.5 times the laboratory's upper limit of normal at Screening; 9. Liver aminotransferase levels greater than 1.5 times the laboratory's upper limit of normal at Screening; 10. Electrocardiogram (ECG) at Screening shows abnormalities which, in the judgment of the Investigator, are clinically significant and could, in the judgment of the Principal Investigator, compromise subject safety; 11. Active gastrointestinal disease which could interfere with the absorption of oral medication; 12. Pregnancy, planned pregnancy, lactation, or inadequate contraception as judged by the Investigator; 13. Active drug or alcohol dependence; 14. History of depression or suicidal ideation within the past year; 15. Concomitant use of strong cytochrome P450 inducers, eg, rifampin, phenobarbital, phenytoin, carbamazepine; 16. Previous participation in a CF101 clinical trial; 17. 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; 18. Participation in another investigational drug or vaccine trial concurrently or within 30 days prior to the Screening visit.
This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.
Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.
Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.
Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

The disease, disorder, syndrome, illness, or injury that is being studied.
This is a multicenter, randomized, double-blind, placebo- and active-controlled, study in adult males and females, aged 18 to 80 years, inclusive, with a diagnosis of moderate-to-severe chronic plaque psoriasis. Eligible subjects will be randomly assigned to CF101 2 mg, 3 mg, matching apremilast 30 mg BID, or matching placebo, in a 3:3:3:2 ratio. Blinding will be maintained using a double-dummy technique. Medication will be taken orally BID for 32 weeks in a double-blinded fashion, with the option to continue treatment through an Extension Period to 48 weeks. Subjects initially assigned to the placebo group will be re-randomized at Week 16 to either CF101 2 mg, CF101 3 mg, or apremilast (with appropriate dose titration) in a 1:1:1 ratio and treated through Week 32, while subjects originally assigned to 1 of the active treatment groups will remain on that treatment through Week 32. The primary efficacy endpoint will be assessed at Weeks 16 and 32; at Week 32, all subjects will be offered the opportunity to remain on their assigned blinded drug through Week 48 (ie, the Extension Period of Weeks 33-48). Disease will be assessed using PASI , static PGA , the percentage of BSA involved, and PDI. Subjects will return for assessments and a new supply of study medication at Weeks 4, 8, 12, 16, 20, 24, and 28, and for final study assessments at Week 32. For those subjects continuing into the Extension Period, efficacy and safety assessments will also occur at Weeks 36, 40, 44, and 48. PK will be assessed in a subgroup of approximately 120 subjects at Weeks 0, 8, 16, 24 and 32. PK will be assessed through sparse sampling. Assessment of whole blood A3AR expression levels will occur at Screening, Week 16, and Week 32.
