Comparing Two Forms of Sacubitril and Valsartan Tablets in Healthy Volunteers to Check if They Work the Same Way in the Body

1 1 1

What is this study about?

This study involves healthy volunteers and examines two formulations of a medication that combines sacubitril and valsartan. The medications being tested are film-coated tablets containing 97 mg of sacubitril and 103 mg of valsartan. One formulation is a test product called Sacubitrilo/valsartán Normon, and the other is a reference product called Entresto. Both medications are taken by mouth and contain the same active substances in the same amounts.

The purpose of the study is to compare how the body absorbs and processes the test formulation compared to the reference formulation and to show that they work in a similar way in the body. This type of study is called a bioequivalence study, which means researchers want to demonstrate that the two formulations behave similarly when taken by healthy volunteers.

The study follows a crossover design, which means that participants will receive both formulations at different times with a break between doses. Volunteers will take a single dose of each medication under fasting conditions, meaning they will not have eaten before taking the tablets. Blood samples will be collected to measure the levels of sacubitril and valsartan in the body over time. This allows researchers to compare how quickly and how much of each active substance enters the bloodstream with each formulation.

1 Receiving study medication

You will receive a single dose of sacubitril/valsartan tablets. These tablets contain two active substances that work together.

The dose will be 97 mg of sacubitril and 103 mg of valsartan in the form of a film-coated tablet.

You will take the medication by mouth while fasting, which means you will not have eaten before taking the tablet.

2 Crossover design periods

The study uses a crossover replicated design. This means you will receive different formulations of the same medication on separate occasions.

During one period, you will receive the test formulation of sacubitril/valsartan tablets.

During another period, you will receive the reference formulation, which is the commercially available version of the medication.

There will be a washout period between each dose. This is a time gap that allows the previous medication to leave your body completely before you take the next dose.

3 Blood sample collection

Blood samples will be collected from you at specific times after taking each dose.

These samples are used to measure the amount of sacubitril and valsartan in your blood over time.

The measurements include AUC, which shows the total amount of medication absorbed by your body, and Cmax, which is the highest concentration of medication reached in your blood.

Additional measurements will include Tmax, which is the time it takes to reach the highest concentration, and other values that help assess how the medication is processed by your body.

4 Safety monitoring

Throughout the study, your health will be monitored through physical examinations.

Your vital signs such as blood pressure, heart rate, and temperature will be checked.

An electrocardiogram may be performed to monitor your heart’s electrical activity.

Laboratory tests will be conducted, including blood tests for general health markers and urine tests.

Who Can Join the Study?

  • You must be able to understand the study design, objectives, and possible risks, and you must provide your written consent to participate, which means you agree in writing to take part after being fully informed
  • You must be between 18 and 55 years old
  • You must not have any significant physical or mental health conditions that could affect the study
  • You must have normal results from a physical examination, which is when a doctor checks your body for any health problems, and your medical records must not show any important health issues
  • You must have normal results from blood tests, including tests for haematology (which checks your blood cells), coagulation (which checks how your blood clots), biochemistry (which checks chemicals in your blood), serology (which checks for infections like hepatitis B, hepatitis C, and HIV), and urinalysis (which is a urine test)
  • You must have normal vital signs, which include measurements like blood pressure, heart rate, and body temperature, and a normal electrocardiogram, which is a test that records the electrical activity of your heart
  • Both men and women can participate in this study

Who Cannot Join the Study?

  • The study does not include vulnerable populations, which means people who may need special protection or care, such as children, pregnant women, or people who cannot make decisions for themselves
  • You cannot participate if you are not a healthy volunteer, meaning you must be in good health without any significant medical conditions or diseases
  • You cannot participate if you do not meet the required age range set for this study
  • You cannot participate if you have any serious medical conditions that could affect the study results or put your health at risk
  • You cannot participate if you are taking medications that might interact with the study drug sacubitril/valsartan, which is a medicine normally used to treat heart problems
  • You cannot participate if you have allergies or bad reactions to sacubitril, valsartan, or similar medicines
  • You cannot participate if you are pregnant, breastfeeding, or planning to become pregnant during the study
  • You cannot participate if you have problems with your liver or kidneys that affect how your body processes medicines
  • You cannot participate if you have recently taken part in another clinical trial
  • You cannot participate if you use tobacco, alcohol, or drugs in ways that could affect the study results

Trial locations

Investigated drugs:

Sacubitril/valsartan is a combination medication that contains two active substances working together. This medicine is used to help the heart pump blood more effectively. In this trial, researchers are comparing different versions of this medication to make sure they work the same way in the body.

Healthy volunteers – This study involves healthy volunteers, which means the participants do not have any disease or medical condition being studied. Healthy volunteers are individuals who participate in clinical research to help test new medications or treatments without having the illness the drug is intended to treat. They serve as a comparison group to understand how a medication works in people without health problems. In this case, the study examines how the body processes a combination medication containing sacubitril and valsartan. The volunteers help researchers understand the basic effects of the drug in healthy bodies. No disease progression is involved since the participants are healthy individuals.
