Growth hormone-releasing hormone analog
Also known as: Egrifta, Egrifta SV, TH9507
Tesamorelin is a stabilized N-terminally modified analog of the 44-amino-acid human growth hormone–releasing hormone. It activates pituitary GHRH receptors, increasing endogenous growth-hormone release and downstream IGF-1 signaling. In the labeled population this pathway reduces visceral adipose tissue; it is not a general weight-loss mechanism.

To report the effects of tesamorelin, a growth hormone-releasing hormone analogue, on inflammatory and fibrinolytic markers and to relate these effects to changes in visceral adipose tissue (VAT). Four hundred and ten HIV-infected patients with abdominal adiposity were randomized to 2 mg tesamorelin (n = 273) or placebo (n = 137) subcutaneously daily for 26 weeks. Circulating plasminogen activator inhibitor-1 (PAI-1) antigen, tissue plasminogen activator (tPA) antigen, C-reactive protein (CRP), and adiponectin were assessed. At baseline, VAT was significantly associated with PAI-1 antigen (ρ = 0.36, P < 0.001), tPA antigen (ρ = 0.29, P < 0.001), CRP (ρ = 0.18, P < 0.001), and adiponectin...

Tesamorelin, a growth hormone-releasing hormone analogue, decreases visceral adipose tissue (VAT) by 15%-20% over 6-12 months in individuals with human immunodeficiency virus (HIV)-associated abdominal adiposity, but it is unknown whether VAT reduction is directly associated with endocrine and metabolic changes. In 2 phase III, randomized, double-blind studies, men and women with HIV-associated abdominal fat accumulation were randomly assigned (ratio, 2:1) to receive tesamorelin or placebo for 26 weeks. At week 26, patients initially receiving tesamorelin were randomly assigned to continue receiving tesamorelin or to receive placebo for an additional 26 weeks. In per-protocol analysis of...

Tesamorelin is a synthetic analogue of growth hormone-releasing factor (GRF), which increases basal and pulsatile growth hormone (GH) secretion and subsequently increases insulin-like growth factor (IGF)-1. Limited information is available about the pharmacokinetics of this compound. Consequently, the aim of this study was to characterize the population pharmacokinetics of tesamorelin in HIV-infected patients and healthy subjects. A total of 38 HIV-infected patients and healthy subjects receiving subcutaneous tesamorelin doses of 1 or 2 mg administered daily during 14 consecutive days were included in the analysis. An open one-compartment model with first- and zero-order absorption and...

The objective of this analysis was to characterize the time course of selected pharmacodynamic (PD) markers of tesamorelin: growth hormone (GH) and insulin-like growth factor (IGF-1) concentrations in HIV-infected patients and healthy volunteers. A total of 41 subjects in Phase I trials receiving subcutaneous daily doses of 1 or 2 mg of tesamorelin during 14 consecutive days were included in this analysis. A previous pharmacokinetic (PK) model of tesamorelin was used as the input function for the PD model of GH. Tesamorelin was hypothesized to stimulate the secretion of GH in an "episodic" manner, i.e., for a finite duration of time. The resulting PK/PD model of GH was used to describe...

Methodology: WPF-ESR-1.0
Treatment of HIV patients with daily tesamorelin, a growth hormone-releasing factor analogue, for 26 weeks resulted in a significant decrease in visceral adipose tissue (VAT) and improvement in lipids. The objective of the 26-week extension phase was to evaluate long-term safety and effects of tesamorelin. HIV patients with central fat accumulation in the context of antiretroviral therapy were randomized to tesamorelin 2 mg (n = 273) or placebo (n = 137) s.c. daily for 26 weeks. At week 26, patients originally on tesamorelin were rerandomized to 2 mg tesamorelin (T-T group, n = 154) or placebo (T-P group, n = 50), whereas patients originally on placebo were switched to tesamorelin (P-T...

Tesamorelin is the only FDA-approved therapy to treat abdominal fat accumulation in people with HIV (PWH). Phase III clinical trials were conducted prior to the introduction of integrase inhibitors (INSTIs), which are now a mainstay of HIV antiretroviral therapy. We leveraged a randomized double-blind trial of 61 PWH and metabolic dysfunction-associated steatotic liver disease to evaluate the efficacy and safety of tesamorelin 2 mg once daily vs. identical placebo among participants on INSTI-based regimens at baseline. In the parent clinical trial, visceral fat cross-sectional area, hepatic fat fraction, and trunk-to-appendicular fat ratio were quantified using magnetic resonance...

Nonalcoholic fatty liver disease (NAFLD) is a common comorbidity among people living with HIV that has a more aggressive course than NAFLD among the general population. In a recent randomized placebo-controlled trial, we demonstrated that the growth hormone-releasing hormone analog tesamorelin reduced liver fat and prevented fibrosis progression in HIV-associated NAFLD over 1 year. As such, tesamorelin is the first strategy that has shown to be effective against NAFLD among the population with HIV. The current study leveraged paired liver biopsy specimens from this trial to identify hepatic gene pathways that are differentially modulated by tesamorelin versus placebo. Using gene set...

Methodology: WPF-ESR-1.0
In people with HIV who are virally suppressed with antiretroviral therapy, abdominal obesity (AO) is linked to neurocognitive impairment (NCI), potentially due to visceral adiposity, inflammation, and reduced insulin-like growth factor 1 (IGF-1). Tesamorelin, a growth hormone-releasing hormone, reduces AO and increases IGF-1, suggesting that it might mitigate NCI in people with HIV and viral suppression. This 6-month phase 2 randomized open-label clinical trial compared tesamorelin vs standard of care (SOC) for NCI in people with HIV who were virally suppressed and abdominally obese (elevated waist circumference [WC]). Exclusions included conditions other than HIV causing NCI, active...

BackgroundHIV-associated lipodystrophy, a complication of combined antiretroviral therapy (CART), causes significant physical and psychological distress in people living with HIV (PLWH), compromising treatment adherence. Tesamorelin, a growth hormone-releasing hormone (GHRH) analogue, has emerged as a therapeutic option.ObjectiveTo systematically evaluate the efficacy and safety of tesamorelin in HIV-infected individuals with lipodystrophy receiving CART, incorporating GRADE assessment.MethodsWe searched PubMed, https://ClinicalTrials.gov, and Scopus from inception to February 9, 2026, for randomized controlled trials evaluating tesamorelin in HIV-associated lipodystrophy. Mean...

HIV-associated lipodystrophy leads to visceral fat accumulation, metabolic complications, body image concerns, medication non-adherence, and increased cardiovascular risks. We thought to assess the effects of Tesamorelin, a synthetic growth hormone-releasing hormone analogue, that has been proposed as a targeted therapy. We systematically searched PubMed, Embase, Scopus, Web of Science, and CENTRAL through July 2025 for randomized controlled trials (RCTs) evaluating Tesamorelin versus placebo in adults with HIV. Random-effects meta-analysis was applied. Outcomes included changes in body composition, hepatic and metabolic parameters, hormonal markers, and adverse events. Risk of bias was...

Tesamorelin (Egrifta™) is a synthetic analog of human growth hormone-releasing hormone (also known as growth hormone-releasing factor) that stimulates the synthesis and release of endogenous growth hormone. It is the first and, so far, only treatment indicated for the reduction of excess abdominal fat in patients with HIV-associated lipodystrophy. This article reviews the pharmacological properties, clinical efficacy and tolerability of tesamorelin in patients with HIV-associated central fat accumulation. Subcutaneous tesamorelin was effective in reducing visceral adipose tissue (VAT), but did not affect subcutaneous adipose tissue to a clinically significant extent in two 26-week, well...

To evaluate the efficacy and safety of tesamorelin, a growth hormone releasing factor analogue approved by the Food and Drug Administration in November 2010 for the treatment of lipodystrophy associated with HIV infection. Literature was obtained through MEDLINE (1948-November 2011) and International Pharmaceutical Abstracts (1970-October 2011) using the search terms tesamorelin, TH9507, growth hormone releasing factor, and HIV-associated lipodystrophy syndrome. Additional publications were obtained through review of references within primary literature publications as well as pertinent Web sites. All articles published in English identified from the data sources were evaluated and all...

The combination of clinical effectiveness with a variety of adverse side effects from the use of recombinant human growth hormone (rhGH) in therapy for growth hormone (GH)-deficient disorders has led to the development of human growth hormone releasing factor (GFR) analogues, which may be better tolerated. Tesamorelin, a synthetic GFR, has been developed as a potential treatment for a variety of conditions that may be associated with a relative deficiency of GH including HIV-related lipodystrophy. This article reviews the development of tesamorelin and its purported role in HIV-related lipodystrophy and other potential indications. Relevant articles and abstracts were obtained from...
