- Growth Hormone Releasing Factor
Tesamorelin binds to pituitary growth hormone-releasing factor (GRF) receptors and stimulates the secretion of endogenous growth hormone which has anabolic and lipolytic properties. Growth hormone exerts its effects by interacting with receptors on target cells such as osteoblasts, myocytes, hepatocytes, and adipocytes to promote the reduction of total fat mass. These effects are primarily mediated by IGF-1 produced in the liver and in peripheral tissues.

Use provided diluent only. Reconstitute 2 mg vial with 2.1 mL diluent; gently roll vial for 30 seconds to mix; do not shake. When using 1 mg vials, reconstitute the first 1 mg vial with 2.2 mL diluent; gently roll vial (do not shake) for 30 seconds to mix; reconstitute the second 1 mg vial with the entire solution from first vial; gently roll vial (do not shake) for 30 seconds to mix. Use reconstituted solution immediately after prepared.
SubQ: The abdomen is the preferred site of administration; rotate site within the abdomen. Avoid injection into scar tissue, bruises, or the navel.
Store intact vials refrigerated at 2°C to 8°C (36°F to 46°F). Protect from light and store in original container until time of use. Store diluent, (sterile water for injection), syringes, and needles at 20°C to 25°C (68°F to 77°F). Use reconstituted solution immediately after prepared; do not refrigerate or freeze. Discard if not used immediately.
Cortisone: Tesamorelin may decrease serum concentrations of the active metabolite(s) of Cortisone. Consider therapy modification
Macimorelin: Growth Hormone Products may diminish the diagnostic effect of Macimorelin. Avoid combination
PredniSONE: Tesamorelin may decrease serum concentrations of the active metabolite(s) of PredniSONE. Consider therapy modification
The incidence of adverse reactions generally decreases with treatment continued beyond 26 weeks.

Concerns related to adverse effects:
• Hypersensitivity reactions: Hypersensitivity reactions (eg, pruritus, erythema, flushing, urticaria, rash) may occur. If hypersensitivity is suspected, discontinue and instruct patient to seek immediate medical attention.
• Fluid retention: Use may result in peripheral edema manifested by increased skin turgor and musculoskeletal discomfort. May be transient or resolve upon treatment discontinuation.
• Injection site reactions: Injection site reactions (including erythema, pruritus, pain, irritation, and bruising) may occur; incidence decreases with treatment continued beyond 26 weeks. Rotating the site of injection to different areas of the abdomen may reduce incidence of reactions.
• Diabetes: May increase risk of development of diabetes due to glucose intolerance. Evaluate glucose status prior to treatment initiation; monitor periodically for glucose metabolism changes. Patients with diabetes should be monitored for the development or worsening of retinopathy due to increased IGF-1 levels.
• Malignancy: Release of endogenous growth hormone and increased serum IGF-1 may increase the risk for development or reactivation of malignancies. Use is contraindicated in patients with active malignancies; treatment for prior malignancy should be completed prior to initiation of tesamorelin. IGF-1 levels should be monitored during treatment; consider discontinuing with persistent IGF-1 elevations (eg, >3 standard deviation scores).
• Acute critical illness: Growth hormone is associated with an increased risk of mortality in patients with acute critical illness due to complications following open heart surgery, abdominal surgery, trauma, or acute respiratory failure. Consider discontinuing in critically ill patients.
• Pediatric: Should not be used in children due to risk of excess growth (gigantism) when epiphyses are open.
• Appropriate use: Not indicated for weight loss management. Due to a lack of long-term cardiovascular safety/benefit data, carefully consider whether continuation of treatment is warranted in patients who do not demonstrate efficacy (based on degree of reduction of visceral adipose tissue). There is no data supporting improved compliance of antiretroviral therapy with concomitant tesamorelin.
Serum IGF-1 levels should be monitored at baseline and during therapy due to the potential increased risk of malignancy from sustained elevation of IGF-1 levels. Serum glucose (prior to treatment initiation); monitor periodically for glucose metabolism changes. Monitor for retinopathy in patients with diabetes. Visceral adipose tissue (by waist circumference or CT scan). Monitor for fluid retention.
Pregnancy Risk Factor
Use is contraindicated in pregnant females.
During pregnancy, there is an increased deposition of visceral adipose tissue due to metabolic and hormonal changes. Tesamorelin decreases the deposition of visceral fat and could potentially cause harm to the unborn fetus. If pregnancy occurs during treatment, discontinue tesamorelin.
• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)
• Patient may experience muscle pain, muscle soreness, nausea, or vomiting. Have patient report immediately to prescriber signs of high blood sugar (confusion, fatigue, increased thirst, increased hunger, polyuria, flushing, fast breathing, or breath that smells like fruit), tachycardia, dizziness, passing out, shortness of breath, severe joint pain, painful extremities, burning or numbness feeling, edema, or injection site pain, redness, edema, itching, bleeding, or irritation (HCAHPS).
• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
