简要总结
Comparative randomized, Single dose, Two-treatment, Four-period, Two-sequence, Replicate Crossover Bioequivalence Study to determine the bioequivalence of Amlodipine / valsartan from Amlodipine/Valsartan 10/160 film coated tablets and Exforge10/160 mg film coated tablets (Novartis Pharma, USA).
详细描述
The primary objective of this bioequivalence study is to assess and compare the rate and extent of absorption of a test formulation against a reference formulation, with an additional focus on evaluating the safety profiles of both formulations. This study aims to provide critical insights into the bioequivalence of the two formulations, shedding light on their pharmacokinetic parameters and overall safety in the context of therapeutic efficacy.
Study Design:
The study adopts an Open-label, Two-treatment, Four-period, Two-sequence, Replicate Crossover Bioequivalence Study design to ensure robustness and reliability in the evaluation of bioequivalence. The Replicate Crossover design minimizes the impact of inter-individual variability, allowing for a more accurate assessment of the formulations' performance.
Participant Selection:
A total of 48 healthy Thai volunteers will be recruited to participate in the study. The inclusion criteria involve individuals who meet specific health standards and are willing to comply with the study requirements. The emphasis on recruiting healthy volunteers aims to establish a baseline for comparison, ensuring that any observed differences in absorption and safety can be attributed to the formulations under investigation.

- •Injectable contraceptives e.g. Depo-Provera® will be discontinued at least 6 months prior to check-in in Period
- •Subjects agree to use acceptable non-hormonal contraceptive methods such as condom, diaphragm, foams, jellies, or abstinence for at least 14 days prior to check-in in Period 1 until 14 days after the end of study in Period
- •Female subjects of non-childbearing potential must meet at least one of the following criteria prior to check-in in Period 1:Postmenopausal for at least 1 year or Surgically sterile (bilateral tubal ligation, bilateral oophorectomy or hysterectomy) at least 6 months
- •Male subjects who are willing or able to use effective contraceptive e.g. condom or abstinence after check-in in Period 1 until 14 days after the end of study in Period
- •Able to understand and voluntarily given written informed consent (signed and dated) by the subject prior to participating in this study.
- •Adequate venous access in both arms for the collection of a number of samples during the study
排除标准
- •History of allergic reaction or hypersensitivity to simvastatin or to any excipients of tablet
- •History or evidence of clinically significant renal, hepatic, gastrointestinal, hematological (e.g. anemia), endocrine (e.g. hyper-/ hypothyroid, diabetes), pulmonary or respiratory (e.g. asthma), cardiovascular (e.g. hyper-/hypotension), psychiatric (e.g. depression), neurologic (e.g. convulsant), allergic disease (including drug allergies, but excluding untreated, asymptomatic, seasonal allergies at time of dosing) or any significant ongoing chronic medical illness
- •History or evidence of muscular disease e.g. muscle pain, tenderness, weakness, myopathy or rhabdomyolysis
- •Have high risk for coronavirus infection based on risk assessment questionnaire or diagnosed as confirmed case of coronavirus disease starting in 2019 (COVID-19)

- •History of problems with swallowing tablet or capsule
- •History or evidence of galactose intolerance, the Lapp lactase deficiency or glucose-galactose malabsorption
- •History of sensitivity to heparin or heparin-induced thrombocytopenia
- •Any condition possibly affecting drug absorption e.g. gastrectomy, enterectomy, gastritis or duodenal or gastric ulceration other than appendectomy
- •History of diarrhea or vomiting within 24 hours prior to check-in in each period
- •12-lead ECG demonstrating corrected QT interval (QTc) >450 msec, a QRS Complex (QRS interval) >120 msec or with an abnormality considered clinically significant at screening. If QTc exceeds 450 msec, or QRS exceeds 120 msec, the ECG will be repeated two more times and the average of the three QTc or QRS values will be used to determine the subject's eligibility.
