入选标准
- •Is a male or female between the ages of 18 and 65 years, inclusive.
- •Has been clinically diagnosed with CSU and experiences an acute flare of moderate to severe urticaria symptoms (itch and hive severity UAS score ≥ 2) approximately 1-2 times a month or every other month consistently during the past year while on a chronic treatment. Enrolled subjects will record UAS daily for urticaria and VAS daily for angioedema during the screening period, which will serve as baseline.
- •Has been on a daily chronic treatment for ≥ 6 weeks.
- •Is willing to use a smartphone study application to record study assessments and AEs.
- •Has no medical history of clinically significant hypertension and cardiovascular disease in the last 10 years. Controlled hypertension without beta blocker confirmed by the Investigator is acceptable.
- •At screening, has stable vital signs in the following ranges (after 5 minutes of rest): • Systolic blood pressure (SBP) ≥90 and ≤140 milliliters of mercury (mmHg) • Diastolic blood pressure (DBP) ≥50 and ≤90 mmHg • Heart rate (HR) ≥45 and ≤100 beats per minute (bpm) Note: Each blood pressure (BP) should be taken after at least 5 minutes rest in a chair with back supported, legs uncrossed, and upper arm bared (slight recline for comfort ispermitted). If vital signs are out of range, the Investigator may obtain two additional readings, so that up to 3 consecutive assessments are made within 1 hour.
- •If female, is not pregnant or breastfeeding based on a negative urine pregnancy test at baseline and each clinical site visit.
- •Is able to communicate clearly with the Investigator and staff; able to read, complete questionnaires, and perform study procedures on the smartphone study application.
- •Is willing and able to provide written informed consent prior to participating in the study
排除标准
- •Has a history of clinically significant gastrointestinal, renal, hepatic, neurologic, hematologic, endocrine, oncologic, pulmonary, immunologic, psychiatric, or cardiovascular disease or any other condition which, in the opinion of the Investigator, would jeopardize the safety of the subject or impact the validity of the study results.
- •Has any clinically significant medical condition or physical exam (PE) finding as deemed inappropriate by the Investigator
- •Has abnormal cardiovascular exam at screening including any prior history of myocardial infarction or clinically significant abnormal electrocardiogram (ECG) (e.g., second- or third-degree heart block, uncontrolled arrhythmia, QTcF [Fridericia’s correction] interval >450 msec for male subjects and >470 msec for female subjects).
- •Has had significant traumatic injury or major surgery within 30 days prior to study screening
- •Known hypersensitivity to any compound in the test product, or any other closely related compound (e.g., dihydropyridine-derived molecules).
- •Has participated in a clinical trial within 30 days prior to the first dose of study drug. Participation in an observational (non-interventional) study is not excluded as long as there are no scheduling conflicts with this study
- •Has an immediate family member of the Investigator, or an employee of the study center, with direct involvement in the proposed study, or other studies under the direction of the Investigator or study center or is in a dependent relationship with a study center employee who is involved in the conduct of this study (e.g., spouse, parent, child, sibling), or may consent under duress.
