Arms Assigned Interventions
Experimental: CF101 2 mg Drug: CF101
orally q12h
Other Name: IB-MECA
Placebo Comparator: Placebo Drug: Placebo
orally q12h
Other Name: Dummy pills

Detailed Description:

Eligible patients will be randomly assigned to parallel dosing groups of CF101 2 mg or matching placebo tablets twice daily (BID) in a 1:1 ratio for the 16-week controlled treatment period. Approximately 94 patients will be assigned to each group.

Medication will be taken orally BID for 16 weeks in a double-blinded fashion. At the end of 16 weeks, all patients assigned to CF101 will continue CF101, while patients originally assigned to placebo will be reassigned to CF101.

Assessment of peripheral blood mononuclear cell (PBMC) adenosine A3 receptor (A3AR) expression at baseline and during treatment with CF101 in selected sites.
