Revestive: Uses, Side Effects and Dosage

What REVESTIVE is used for:

REVESTIVE is used to treat adults and pediatric patients 1 year of age and above with Short Bowel Syndrome. Short Bowel Syndrome is a disorder arising from an inability to absorb food nutrients and fluid across the gastrointestinal tract (gut) due to not enough surface area. It is often caused by surgical removal of all or part of the small intestine.

How REVESTIVE works:

REVESTIVE improves the absorption of fluids from your remaining gut by increasing the surface area and function of your remaining gut.

The ingredients in REVESTIVE are:

Medicinal ingredients: teduglutide

One vial of powder contains 5 mg of teduglutide. After reconstitution with 0.5 mL of sterile water for injection, a 10 mg/mL sterile solution is obtained.

Non-medicinal ingredients: dibasic sodium phosphate heptahydrate, L-histidine, mannitol, monobasic sodium phosphate monohydrate. The diluent contains sterile water for injection that is provided in a pre-filled syringe.

REVESTIVE comes in the following dosage forms:

REVESTIVE is a powder and diluent for solution for under the skin (subcutaneous) injection (5 mg powder in a vial and 0.5 mL diluent in a pre-filled syringe). Pack size of 28 each.

The powder is white and the diluent is clear and colorless.

Do not use REVESTIVE if:

• you are allergic to teduglutide or any of the other ingredients of this medicine;
• you have or are suspected to have cancer in the gastrointestinal tract, including liver, gallbladder, bile ducts or pancreas;
• you have had cancer in the gastrointestinal tract, including liver, gallbladder, bile ducts or pancreas, within the last five years

To help avoid side effects and ensure proper use, talk to your healthcare professional before you take REVESTIVE. Talk about any health conditions or problems you may have, including if you:

• have a history of bowel obstruction. Your doctor will consider this when prescribing this medicine.
• suffer from certain cardiovascular diseases (affecting the heart and/or blood vessels) such as high blood pressure (hypertension) or have a weak heart (cardiac insufficiency). The symptoms include sudden weight gain, swollen ankles and/or shortness of breath. This may require closer monitoring and more frequent changes to the amount of parenteral nutrition/IV fluid that you receive.
• have decreased kidney function. Your doctor may need to give you a lower dose of this medicine.
• have severely decreased liver function. Your doctor will consider this when prescribing this medicine.

Medical check-ups before and during treatment with REVESTIVE

Colonoscopy Schedule in Adults

Before you start treatment with this medicine, your doctor will need to perform a colonoscopy (a procedure to see inside your colon and rectum) to check for the presence of polyps (small growths that may be normal or abnormal) and remove them. It is recommended that your doctor performs a follow-up colonoscopy between 1 to 2 years after starting treatment, and then at a minimum of 5 year intervals. If polyps are found either before or during your treatment with REVESTIVE, your doctor will decide whether you should continue using this medicine. REVESTIVE should not be used if a cancer is detected during your colonoscopy.Similarly, your doctor may check the upper part of the bowel before and during treatment with Revestive.

Colonoscopy Schedule in Children (ages 1 through 17 years)

Before your child starts treatment with this medicine, your doctor will need to test for any hidden blood in the stool. If there is sign of unexplained blood in the stool, a colonoscopy will be required (a procedure to see inside your child's colon, rectum and the large intestine). It is recommended that your child's doctor tests for hidden blood in the stool every year while your child is receiving REVESTIVE.

Colonoscopy is recommended for all children after 1 year of treatment, every 5 years thereafter while on continuous treatment with REVESTIVE, and if they have new or unexplained blood in the stool.

Laboratory Testing

Your doctor will take special care and monitor your small bowel function and monitor for signs and symptoms indicating problems with your gallbladder, liver and pancreas by conducting initial laboratory tests (bilirubin, alkaline phosphatase, lipase and amylase) within 6 months before starting treatment with REVESTIVE and every 6 months while you are using REVESTIVE. If there is significant increase in test results, more tests may be needed (for example, imaging of the biliary tract, liver, or pancreas).

Tell your healthcare professional about all the medicines you take, including any drugs, vitamins, minerals, natural supplements or alternative medicines.

REVESTIVE may affect how other medicines are absorbed from the gut and therefore how well they work. Your doctor may have to change your dose of other medicines.

How to take REVESTIVE:

Always use this medicine exactly as your doctor has told you. Check with your doctor, pharmacist or nurse if you are not sure.

REVESTIVE is injected under the skin (subcutaneously) once daily. The injection can be self-administered or given by another person, for example your doctor, his/her assistant or your home nurse. If you are injecting the medicine yourself, you must receive adequate training by your doctor or nurse. Do not use the same area each day for each injection.

NOTE: Before you start, make sure you have a clean work surface and that you have washed your hands before proceeding.

1. 1. Assemble the pre-filled syringe

Once you have all the materials ready, you need to assemble the pre-filled syringe. The following procedure shows how you do this.

1. 1.1 Take the pre filled syringe with diluent and flip off the top part of the white plastic cap so that it is ready for the reconstitution needle to be attached.

1. 1.2 Attach the reconstitution needle (e.g. 22G, 1½" (0.7 x 40 mm)) to the assembled pre-filled syringe by screwing it on in a clockwise direction.
2. 2. Dissolve the powder

Now you are ready to dissolve the powder with the diluent.

1. 2.1 Remove the green flip-off button from the powder vial, wipe the top with an alcohol wipe and allow to dry. Do not touch the top of the vial.

1. 2.2 Uncap the reconstitution needle on the assembled pre-filled syringe with diluent without touching the tip of the needle.

1. 2.3 Taking the powder vial, insert the reconstitution needle attached to the assembled pre-filled syringe into the centre of the rubber stopper and gently push the plunger all the way down to inject all the diluent into the vial.

1. 2.4 Leave the reconstitution needle and empty syringe in the vial. Let the vial rest for approximately 30 seconds.

1. 2.5

   Gently roll the vial between your palms for about 15 seconds. Then gently turn the vial upside-down once with the reconstitution needle and empty syringe still in the vial.

   NOTE: Do not shake the vial. Shaking the vial may produce foam, which makes it difficult to extract the solution from the vial.

1. 2.6 Let the vial rest for about two minutes.
2. 2.7 Observe the vial for any undissolved powder. If any powder remains, repeat steps 2.5 and 2.6. Do not shake the vial. If there is still some undissolved powder, discard the vial and start the preparation again from the beginning with a new vial.

NOTE: The final solution should be clear. If the solution is cloudy or contains particulate matter, do not inject it.

NOTE: The product should be used within 3 hours after reconstitution.

1. 3. Prepare the injection syringe

1. 3.1 Remove the reconstitution syringe from the reconstitution needle which is still in the vial and discard the reconstitution syringe.

1. 3.2 Take the injection syringe and attach it to the reconstitution needle which is still in the vial.

1. 3.3 Turn the vial upside down, slide the tip of the reconstitution needle close to the stopper and allow ALL the medicine to fill the syringe by pulling the plunger back gently.

NOTE: If your doctor has told you that you need two vials, prepare a second pre-filled syringe with diluent and a second powder vial as shown in the main steps 1 and 2. Withdraw the solution from the second vial into the same injection syringe by repeating step 3.

1. 3.4 Remove the injection syringe from reconstitution needle leaving the needle in the vial. Discard the vial and reconstitution needle together into the sharps disposal container.

1. 3.5 Take the injection needle (Adults: e.g. 26G, 5/8" [0.45 x 16 mm]) or (Pediatrics: e.g. 30G, ½" [0.31 x 12.7 mm]), but do not remove the plastic needle cap. Attach the needle to the injection syringe containing the medicine.

1. 3.6 Check for air bubbles. If air bubbles are present, gently tap the syringe until they rise to the top. Then gently push up the plunger to expel the air.

1. 3.7 Your dose in mL has been calculated by your doctor. Expel any excessive volume from the syringe with the needle cap still on until your dose is reached.
2. 4. Inject the solution

1. 4.1 Find an area on your belly, upper arm, or on your thigh where it is easy for you to give the injection (see the diagram).

NOTE: Do not use the same area each day for each injection - rotate sites (use upper, lower, and left and right side of your belly, or either upper arm or thigh) to avoid discomfort. Avoid areas that are inflamed, swollen, scarred or covered by a mole, birthmark or other lesion.

1. 4.2 Clean the intended site of injection on your skin with an alcohol swab, using a circular motion, working outwards. Allow the area to air-dry.

1. 4.3 Remove the plastic cap from the needle of the prepared injection syringe. Gently grasp the cleaned skin at the injection site with one hand. With the other hand, hold the syringe as you would with a pencil. Bend your wrist back and quickly insert the needle at a 45° angle.
2. 4.4 Pull back the plunger slightly. If you see any blood in the syringe, withdraw the needle and replace the needle on the injection syringe with a clean one of the same size. You can still use the medicine that is already in the syringe. Try to inject in another place in the cleaned skin area.
3. 4.5 Inject the medicine slowly by pushing steadily on the plunger until all the medicine is injected and the syringe is empty.
4. 4.6 Pull the needle straight out of the skin and discard the needle and syringe together into the sharps disposal container. A small amount of bleeding may occur. If necessary, press gently on the injection site with an alcohol swab or 2x2 gauze until any bleeding has stopped.

Dispose all needles and syringes in a sharps disposal container or hard-walled container (for example, a detergent bottle with a lid). This container must be puncture proof (top and sides). If you need a sharps disposal container, please contact your doctor.
