A Bioequivalence Study of Losartan Potassium Tablets (Containing Losartan Potassium 100 mg) in Normal, Healthy, Adults Under Fasting Conditions

NCT ID: NCT03459911

Last Updated: 2018-11-02

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE1
• Total Enrollment: 66 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2018-02-16
• Study Completion Date: 2018-03-16

Brief Summary

To demonstrate bioequivalence of single dose test formulation of Losartan potassium tablets (containing Losartan potassium 100 mg) of Pharmtechnology LLC, Republic of Belarus with reference Cozaar® (containing Losartan potassium 100 mg) of "Merck Sharpe & Dohme B.V.", Haarlem, the Netherlands in normal, healthy, adult, human subjects under fasting conditions.To monitor adverse events and ensure the safety

Detailed Description

Total 66 normal healthy adult subjects will be enrolled in the study. Subjects will be administered either the Test or the Reference Product with 200 mL of water in each period as per the randomization schedule. Subjects will fast for at least 10 hours prior to administration of the study drugs and for four (4) hours after administration of the study drugs during each study period. Standardized meals will be provided in each study period. Water will not be accessible to the subjects 1 hour to administration of the study drugs and 1 hour after administration of the study drugs in each period. A total of 29 blood samples will be withdrawn for pharmacokinetic profiling during each study period. The plasma concentrations of losartan and its carboxylic acid metabolite will be measured by a validated LC-MS/MS analytical method. ANOVA will be performed on log transformed pharmacokinetic parameters Cmax, AUC0-t, AUC0-∞, and 90% confidence interval will be constructed for the ratio of geometric least square mean of the Test and Reference products, obtained from the log-transformed data. Bioequivalence will be concluded if the ratio estimate as well as its 90% confidence interval, both falls within the acceptable range of 80.00% to 125.00% for Cmax, AUC0-t.

4. Subjects should not have any medical history of significant diseases.

5. If subject is a female and is

• of child bearing potential, she should be practicing an acceptable method of birth control for the duration of the study as suggested by the investigator, such as a combination of male condom with either cap, diaphragm or sponge with spermicide (double barrier method), intrauterine device (IUD), or abstinence.

OR

• surgically sterile, bilateral tubal ligation done at least 6 months before the study should be documented.

8. Subjects who are non-smokers based on history.

9. Subjects willing to adhere to the protocol and the following study requirements:

• Should not consume xanthine containing products, such as coffee, tea, chocolate or soft drinks at least 48 hours prior to dosing (i.e. in-house monitoring and the remaining based on history) until the last sample collection.
• Should not consume alcohol at least 48 hours prior to dosing (i.e. during in-house monitoring and the remaining based on history) until the last sample collection.
• Should not consume grapefruit or its products at least 7 days prior to each dosing (i.e. during in-house monitoring and the remaining based on history) and until the last sample collection.

10. Subjects having no clinically significant medical history and no clinically significant abnormalities in general physical examination, laboratory assessments, 12-lead ECG, chest X-Ray or vital signs.

5. Subjects with abnormalities in resting heart rate (>100 beats/min or <50 beats/min), blood pressure either hypotensive episode (systolic blood pressure <90 mmHg or diastolic blood pressure <60 mmHg) or hypertension (systolic blood pressure ≥ 140 mmHg or diastolic blood pressure ≥90 mmHg), oral temperature (< 95.60F or > 990F) on the screening day.
