Recurrent Pericarditis

Brief summary

Patients with recurrent pericarditis who are refractory or intolerant to current therapeutic management options or who require long-term administration of corticosteroids to control their disease are particularly challenging to manage. The pathogenesis of pericarditis involves the activation of the inflammasome. CardiolRxTM (a pure cannabidiol \[CBD\] solution) is known to have anti-inflammatory properties, including modulation of inflammasome signaling. This pilot study is to assess the tolerance and safety of CardiolRxTM during the resolution of pericarditis symptoms, assess improvement in objective measures of disease, and during the extension period, assess the feasibility of weaning concomitant background therapy including corticosteroids while taking CardiolRxTM.

Detailed description

Multi-center, open label Pilot Study. Patients who present with recurrent pericarditis will be screened and informed consent obtained. Baseline assessments include the following: Clinical assessment, including vital signs, highest NRS pain score within the past 7 days of Day 1, 12-lead ECG; C-SSRS as well as hematology and blood chemistry and a pregnancy test for women with child-bearing potential. Concomitant medications are recorded and any (S)AEs after informed consent has been obtained. Study treatment will be initiated in the evening of Day 1, after all baseline assessments are completed. Oral administration is as follows: * Initial starting dose (Day 1 p.m. dose to Day 3 a.m. dose): 5 mg/kg of body weight CardiolRxTM * Day 3 p.m. dose to Day 10 a.m. dose: 7.5 mg/kg of body weight CardiolRxTM b.i.d. * Day 10 p.m. dose to end of treatment period: 10.0 mg/kg of body weight CardiolRxTM b.i.d. If the next higher dose after each study drug increase is not tolerated, the dose will be reduced to the previous tolerated dose. Unless contraindicated in the opinion of the investigator, after 8 weeks of treatment, patients will enter an 18-week extension period (EP), in which they continue study treatment while their concomitant medications will be weaned. Follow-up Procedures Every visit (before the next dose increase) the patient will be re-evaluated. This includes ECG monitoring at approximately 5 hours post-morning dose (Tmax) to surveil for deleterious effects on ECG intervals (particularly the QTc interval) and rhythm. Drug titration will be dependent on investigator or designate interrogation of the ECGs and the absence of new, clinically significant abnormalities on those ECGs. Vital signs, concurrent medication and (S)AEs will be recorded at all visits. Blood chemistry including liver function tests, hematology as well as INR assessments will be carried out at selected visits. Final efficacy assessments will take place after 26 weeks of study treatment and include a clinical assessment, vital signs, pain score NRS, a 12-lead ECG, the C-SSRS, as well as laboratory assessments. For patients who do not enter the EP, Final assessments will be done after 8 weeks.
