Brief summary
This is a open label randomized, multi-center study conducted in Taiwan. The study aims to evaluate the effectiveness and safety of oral Rhynorm (A drug) and Rytmonorm (B drug) for the conversion of paroxysmal AF and is designed to evaluate the improvement in sinus rhythm restoration after the treatment with Rhynorm (A drug) and Rytmonorm (B drug) for 24 weeks.
Detailed description
This is a open label randomized, multi-center study conducted in Taiwan. The study aims to evaluate the effectiveness and safety of oral Rhynorm (A drug) and Rytmonorm (B drug) for the conversion of paroxysmal AF and is designed to evaluate the improvement in sinus rhythm restoration after the treatment with Rhynorm (A drug) and Rytmonorm (B drug) for 24 weeks. This study comprised of three phases: a screening phase, a washout run-in qualifying phase lasting about 7 days, and a treatment phase of 24 weeks. A total of 60 evaluable subjects is planned to be enrolled. With an estimation of 20% dropout rate, 72 patients will be enrolled to reach 60 evaluable patients at the end of study. After screening for eligibility, the eligible subjects will be randomly assigned to either of the two gruop. The two-group are shown in the following table. Group Treatment Drug Group A Rhynorm (A drug) Group B Rytmonorm (B drug) Patients with arrhythmia will be screened for eligibility after providing informed consent. Patients present with the symptoms of arrhythmia after withdrawn from other prohibited anti-AF agents for at least 7 days and completed run-in period event recorded will be qualified for entering this study and will be randomized to Rhynorm (A drug) treatment group or Rytmonorm (B drug) reference drud group in a 1:1 ratio. The clinical evaluation will be recorded during the study period. Before treating with Rhynorm (A drug) and Rytmonorm (B drug), the physical examination and condition will be tracked and recorded for at least 7 days as the historical data. During the treatment period, the subjects still had a routine OPD visit. Record symptom event and event recorder monitoring on OPD visit. Safety assessments on all randomized subjects include adverse events, vital signs, and laboratory tests (hematology and biochemistry). Any adverse events, symptom events and concomitant medications/therapies will be recorded on the CRFs throughout the study.
