Tesamorelin was developed by Theratechnologies Inc. and is marketed under the brand name Egrifta (tesamorelin for injection).

Mechanism of Action # GHRH Receptor Activation # Tesamorelin binds to and activates the GHRH receptor (GHRHR), a G-protein coupled receptor expressed primarily on somatotroph cells of the anterior pituitary gland.

Downstream Metabolic Effects # The GH released in response to tesamorelin exerts its metabolic effects both directly and through hepatic production of IGF-1.

These effects may contribute to the improvements in lipid parameters observed in tesamorelin clinical trials, including reductions in triglycerides and total cholesterol in some study populations.

Notably, an extension study examining the durability of response found that discontinuation of tesamorelin led to reaccumulation of visceral fat, indicating that ongoing treatment is necessary to maintain the metabolic benefit.

An area of active investigation is the potential role of tesamorelin in nonalcoholic steatohepatitis (NASH) and hepatic steatosis.

A small randomized trial investigated tesamorelin's effects on cognitive function in healthy older adults and found improvements in executive function and verbal memory compared to placebo over a 20-week treatment period.

Glucose Metabolism Concerns # GH is a counter-regulatory hormone that opposes insulin action, and tesamorelin has been associated with modest increases in fasting glucose and HbA1c in some clinical trials.

The relative efficacy and safety of tesamorelin compared to these alternatives remain undefined.

Reported side effects of Tesamorelin include injection site reactions, arthralgia.

Most reported side effects are mild and transient.

Consult the detailed side effects profile for full information.

Given epidemiological associations between elevated IGF-1 and increased risk of certain malignancies, this is a theoretical concern, particularly in a population (HIV-infected individuals) with baseline elevated cancer risks.

Extrapolation of efficacy to non-HIV populations requires caution given the unique pathophysiology of HIV-associated lipodystrophy, including the contributions of antiretroviral drugs, chronic inflammation, and immune dysregulation.

For patients with pre-existing insulin resistance, a common feature of HIV-associated metabolic disease, the potential for glucose dysregulation warrants monitoring.

Hepatic and Cognitive Indications # The NASH and cognitive function data, while scientifically compelling, derive from relatively small trials with limited follow-up.

However, larger confirmatory trials with longer follow-up are necessary before any cognitive indications can be considered evidence-based.
