study of bisoprolol (nerkardou - nerhadou international) 5 and 10 mg oral dissolvable film (odf) treatment in egyptian patients with essential hypertension

Conditions: Essential Hypertension

Summary: the trial is designed to assess the safety and investigation of the efficacy of a single oral dose of bisoprolol (nerkardou - nerhadou) oral dissolvable film (odf) 5 \& 10 mg, and patients' compliance in the treatment of essential hypertension. this is a phase iv, open-label, single-arm, prospective trial where subjects will receive: 1. bisoprolol (nerkardou) at an initial dose of 5 (mg) milligrams once daily for 2 weeks. 2. if the blood pressure would be greater than or equal to 130/80 mmhg after 2 weeks, then the dose will be titrated to 10 mg once daily (non-responders). dose-titration will be done at any follow-up visit based on the response. 3. the total duration of study treatment will be 12 weeks ±2 days, and the total sample size of the study will be 406 participants.

the trial is designed to assess the safety and investigation of the efficacy of a single oral dose of bisoprolol (nerkardou - nerhadou) oral dissolvable film (odf) 5 \& 10 mg \& patients' compliance in the treatment of essential hypertension. this is a phase iv, open-label, single-arm, prospective trial where subjects will receive: the subject will initially administer once daily 5 mg bisoprolol (nerkardou) oral dissolvable film (odf) for 2 weeks. after the assessment of the subject being a responder, study medication will be maintained till week 12. response will be assessed for each patient every 2 weeks and dose-titration will be done based on the response and pi decision at any visit. then, for responders, once daily 5 mg bisoprolol (nerkardou) oral dissolvable film (odf will be administered for the subsequent 2 weeks. for non-responders once daily 10 mg bisoprolol (nerkardou) oral dissolvable film (odf) will be administered for the subsequent 2 weeks. for those who are still not responding to the higher dose will be shifted to other alternatives according to their merit and they will be included to intention to treat. a responder is defined by bp response, which is represented in the form of a ≥20 mmhg decreases in sitting through sbp and a ≥10 mmhg decreases in sitting through dbp, or a sitting through sbp of \<130 mmhg and a sitting through dbp of \<80 mmhg. the total duration of study treatment will be 12 week (±2days). (flow chart of trail design appendix iii) and the total sample size of the study will be 406 participants. the trial has a duration of approximately 14 weeks, including: 1. screening (assessments to determine eligibility for entry into the trial, occurring within 14 days to day 1 before treatment initiation (week -2) to (week 0). 2. treatment duration (5 mg or 10 mg bisoprolol (nerkardou) based on the response) (duration of 12 weeks); from day 1 (week 1) to the end of day 84 ±2days (week 12 ±2days) 3. premature withdrawal/ early discontinuation
