Tesamorelin: a growth hormone-releasing factor analogue for HIV-associated lipodystrophy.
Tesamorelin may help reduce visceral fat and improve body image in patients with HIV-related lipodystrophy, but cost and long-term safety data are concerns.

this study against the rest of the tesamorelin corpusSummary and findings
The study evaluated the efficacy and safety of tesamorelin, a growth hormone-releasing factor analogue, in patients with HIV-associated lipodystrophy. Significant decreases in waist circumference and visceral adipose tissue were observed after 26 weeks of treatment. The study also noted improvements in subjective body image parameters.
Abstract
<h4>Objective</h4>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.<h4>Data sources</h4>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.<h4>Study selection and data extraction</h4>All articles published in English identified from the data sources were evaluated and all pertinent information was included. All studies relevant to the evaluation of efficacy and safety of tesamorelin in the management of HIV-associated lipodystrophy were included, with a focus on trials completed in humans.<h4>Data synthesis</h4>In 2 Phase 3 clinical trials and their pooled analyses, tesamorelin was proven to significantly decrease waist circumference and visceral adipose tissue (VAT) following 26 weeks of treatment. Both trials also demonstrated significant improvements in some subjective body image parameters. Both studies had 26-week extension phases that confirmed maintenance of VAT improvements on treatment without adverse impact on blood glucose and lipid parameters. Limited data support off-label uses of tesamorelin at this time.<h4>Conclusions</h4>Tesamorelin is effective in improving visceral adiposity and body image in patients with HIV-associated lipodystrophy over 26-52 weeks of treatment. Potential limitations for its use include high cost and lack of long-term safety and adherence data. Tesamorelin provides a useful treatment option for management of patients with significant lipodystrophy related to HIV infection.
