1. what sandostatin lar is and what it is used for

Sandostatin LAR is a synthetic compound derived from somatostatin. Somatostatin is normally found in the human body, where it inhibits the release of certain hormones such as growth hormone. The advantages of Sandostatin LAR over somatostatin are that it is stronger and its effects last longer.

• Sandostatin LAR is used to treat acromegaly, Acromegaly is a condition where the body produces too much growth hormone. Normally, growth hormone controls growth of tissues, organs, and bones. Too much growth hormone leads to an increase in the size of bones and tissues, especially in the hands and feet. Sandostatin LAR markedly reduces the symptoms of acromegaly, which include headache, excessive perspiration, numbness of the hands and feet, tiredness, and joint pain. In most cases, the overproduction of growth hormone is caused by an enlargement in the pituitary gland (a pituitary adenoma); Sandostatin LAR treatment may reduce the size of the adenoma.

Sandostatin LAR is used to treat people with acromegaly:

• – when other types of treatment for acromegaly (surgery or radiotherapy) are not suitable or haven’t worked; – after radiotherapy, to cover the interim period until the radiotherapy becomes fully effective.

• to relieve symptoms associated with overproduction of some specific hormones and other related substances by the stomach, bowels or pancreas,

Overproduction of specific hormones and other related natural substances can be caused by some rare conditions of the stomach, bowels or pancreas. This upsets the natural hormonal balance of the body and results in a variety of symptoms, such as flushing, diarrhoea, low blood pressure, rash, and weight loss. Treatment with Sandostatin LAR helps to control these symptoms.

• to treat neuroendocrine tumours located in the gut (e.g. appendix, small intestine or colon) Neuroendocrine tumours are rare tumours which can be found in different parts of the body. Sandostatin LAR is also used to control the growth of these tumours, when they are located in the gut (e.g. appendix, small intestine or colon).
• to treat pituitary tumours that produce too much thyroid-stimulating hormone (TSH).

Too much thyroid-stimulating hormone (TSH) leads to hyperthyroidism. Sandostatin LAR is used to treat people with pituitary tumours that produce too much thyroid-stimulating hormone (TSH):

• – when other types of treatment (surgery or radiotherapy) are not suitable or have not worked; – after radiotherapy, to cover the interim period until the radiotherapy becomes fully effective.

2. what you need to know before you use sandostatin lar

Follow all instructions given to you by your doctor carefully. They may differ from the information contained in this leaflet.

How much Sandostatin LAR to use

Acromegaly

It is recommended to start treatment with the administration of 20 mg Sandostatin LAR at 4-week intervals for 3 months. Patients on treatment with s.c. Sandostatin can start treatment with Sandostatin LAR the day after the last dose of s.c. Sandostatin. Subsequent dosage adjustment should be based on serum growth hormone (GH) and insulin-like growth factor-1/somatomedin C (IGF-1) concentrations and clinical symptoms.

For patients in whom, within this 3-month period, clinical symptoms and biochemical parameters (GH; IGF-1) are not fully controlled (GH concentrations still above 2.5 microgram/L), the dose may be increased to 30 mg every 4 weeks. If after 3 months, GH, IGF-1, and/or symptoms are not adequately controlled at a dose of 30 mg, the dose may be increased to 40 mg every 4 weeks.

For patients whose GH concentrations are consistently below 1 microgram/L, whose IGF-1 serum concentrations normalised, and in whom most reversible signs/symptoms of acromegaly have disappeared after 3 months of treatment with 20 mg, 10 mg Sandostatin LAR may be administered every 4 weeks. However, particularly in this group of patients, it is recommended to closely monitor adequate control of serum GH and IGF-1 concentrations, and clinical signs/symptoms at this low dose of Sandostatin LAR.

For patients on a stable dose of Sandostatin LAR, assessment of GH and IGF-1 should be made every 6 months.

Gastro-entero-pancreatic endocrine tumours

• Treatment of patients with symptoms associated with functional gastro-entero-pancreatic neuroendocrine tumours

It is recommended to start treatment with the administration of 20 mg Sandostatin LAR at 4-week intervals. Patients on treatment with s.c. Sandostatin should continue at the previously effective dosage for 2 weeks after the first injection of Sandostatin LAR.

For patients in whom symptoms and biological markers are well controlled after 3 months of treatment, the dose may be reduced to 10 mg Sandostatin LAR every 4 weeks.

For patients in whom symptoms are only partially controlled after 3 months of treatment, the dose may be increased to 30 mg Sandostatin LAR every 4 weeks.

For days when symptoms associated with gastro-entero-pancreatic tumours may increase during treatment with Sandostatin LAR, additional administration of s.c. Sandostatin is recommended at the dose used prior to the Sandostatin LAR treatment. This may occur mainly in the first 2 months of treatment until therapeutic concentrations of octreotide are reached.

• Treatment of patients with advanced Neuroendocrine Tumours of the midgut or of unknown origin where non-midgut sites of origin have been excluded

The recommended dose of Sandostatin LAR is 30 mg administered every 4 weeks. Treatment with Sandostatin LAR for tumour control should be continued in the absence of tumour progression.

Treatment of TSH-secreting adenomas

Treatment with Sandostatin LAR should be started at a dose of 20 mg at 4-weekly intervals for 3 months before considering dose adjustment. The dose is then adjusted on the basis of the TSH and thyroid hormone response.

Instructions for preparation and intramuscular injection for Sandostatin LAR

FOR DEEP INTRAMUSCULAR INJECTION ONLY

Included in the injection kit:

• a. One vial containing Sandostatin LAR powder,

• b. One prefilled syringe containing the vehicle solution for reconstitution,

• c. One vial adapter for drug product reconstitution,

• d. One safety injection needle.

Follow the instructions below carefully to ensure proper reconstitution of Sandostatin LAR before deep intramuscular injection.

There are 3 critical actions in the reconstitution of Sandostatin LAR. Not following them could result in failure to deliver the drug appropriately.

• The injection kit must reach room temperature. Remove the injection kit from the fridge and let the kit stand at room temperature for a minimum of 30 minutes before reconstitution, but do not exceed 24 hours.
• After adding the diluent solution, ensure that the powder is fully saturated by letting the vial stand for

5 minutes.,

• After saturation, shake the vial moderately in a horizontal direction for a minimum of 30 seconds until a uniform suspension is formed. The Sandostatin LAR suspension must only be prepared immediately before administration.

Sandostatin LAR should only be administered by a trained healthcare professional.

Step 1

• Remove the Sandostatin LAR injection kit from refrigerated storage.

ATTENTION: It is essential to start the reconstitution process only after the injection kit reaches room temperature. Let the kit stand at room temperature for a minimum of 30 minutes before reconstitution, but do not exceed 24 hours.

Note: The injection kit can be re-refrigerated if needed.

Step 2

• Remove the plastic cap from the vial and clean the rubber stopper of the vial with an alcohol wipe.
• Remove the lid film of the vial adapter packaging, but do NOT remove the vial adapter from its packaging.
• Holding the vial adapter packaging, position the vial adapter on top of the vial and push it fully down so that it snaps in place, confirmed by an audible “click.”
• Lift the packaging off the vial adapter with a vertical movement.
• At this stage prepare the patient for injection.
• After the saturation period, make sure that the plunger is pushed all the way down in the syringe.

ATTENTION : Keep the plunger pressed and shake the vial moderately in a horizontal direction for a minimum of 30 seconds so that the powder is completely suspended (milky uniform suspension). Repeat moderate shaking for another 30 seconds if the powder is not completely suspended.

Step 6

• Turn syringe and vial upside down, slowly pull the plunger back and draw the entire contents from the vial into the syringe.
• Unscrew the syringe from the vial adapter.
• Screw the safety injection needle onto the syringe.
• If immediate administration is delayed, gently re-shake the syringe to ensure a milky uniform suspension
• Prepare injection site with an alcohol wipe.
• Pull the protective cover straight off the needle.
• Gently tap the syringe to remove any visible bubbles and expel them from the syringe.
• Proceed immediately to Step 8 for administration to the patient. Any delay may result in sedimentation.
• Sandostatin LAR must be given only by deep intramuscular injection, NEVER intravenously.
• Insert the needle fully into the left or right gluteus at a 90° angle to the skin.
• Slowly pull back the plunger to check that no blood vessel has been penetrated (reposition if a blood vessel has been penetrated).
• Depress the plunger with steady pressure until the syringe is empty. Withdraw the needle from the injection site and activate the safety guard (as shown in Step 9).

Step 9

• Activate the safety guard over the needle in one of the two methods shown:

• – either press the hinged section of the safety guard down onto a hard surface (figure A)

• – or push the hinge forward with your finger (figure B).

• An audible “click” confirms the proper activation.
• Dispose of syringe immediately (in a sharps container).
