In two multicenter, randomized, placebo-controlled trials, patients experienced a:

Statistically Significant Reduction in excess visceral abdominal fat vs placebo

The safety and efficacy of EGRIFTA SV® (2 mg/vial formulation) have been established based on clinical studies with EGRIFTA® (1 mg/vial formulation), as well as a demonstration of comparable bioequivalence between the 1.4 mg EGRIFTA SV® dose (2 mg/vial formulation) and the 2 mg EGRIFTA® dose (1 mg/vial formulation).

Clinical trials:

Main phase – 26 Weeks

Treatment for at least 26 weeks resulted in significant reduction in excess visceral abdominal fat
Continued treatment through 52 weeks maintained the reduction in excess visceral abdominal fat

Extension phase – 52 Weeks†

Patients receiving tesamorelin for the full 52-week study period maintained reduction of excess visceral abdominal fat from weeks 26-52.

Change in Excess Visceral Abdominal Fat over time†

Patients on tesamorelin for injection for the full 52-week study period maintained reduction of excess visceral abdominal fat from weeks 26–52

†Change from week 26 to week 52 in excess visceral abdominal fat by treatment group (tesamorelin for injection week 0-52 or tesamorelin for injection week 0-26 and placebo week 26-52).

Post-hoc responder analysis

The results of the post-hoc analysis were not part of the New Drug Application (NDA), therefore were not reviewed by the FDA to support approval of EGRIFTA®.

In a post-hoc responder analysis of data from two multicenter, randomized, placebo-controlled trials:

Excess visceral abdominal fat significantly decreased from baseline in responders1,2

  • Amount of abdominal fat decreased toward a normal level (130 cm2) in responders.1 A level of <130 cm2 has been associated with lower risk of adverse health outcomes3,4
  • The responder rate (predefined criteria of ≥8% reduction in excess visceral abdominal fat) was 69% at 26 weeks and 72% at 52 weeks for patients treated with tesamorelin for injection1

EGRIFTA SV® is not approved for use in clinical conditions other than the reduction of excess visceral abdominal fat.
EGRIFTA SV® is not indicated for weight loss management.

Clinical study design

Two multicenter, randomized, double blind, placebo-controlled phase 3 studies in 816 HIV-infected patients with excess visceral abdominal fat (N=412 in study 1; N=404 in study 2). Each study consisted of a main phase (26 weeks) followed by an extension phase (26 weeks).

Patients were randomized for each phase of the study.

Patients were on a stable anti-retroviral treatment regimen for at least 8 weeks prior to randomization. The primary efficacy endpoint was percent change from baseline in excess abdominal fat vs placebo at week 26. Changes in visceral adipose tissue vs week 26 baseline were also calculated at week 52. Amounts of excess abdominal fat and any changes in this were assessed using computed tomography (CT) scans at the L4-L5 vertebral level.

Post-hoc analysis design

In multicenter, randomized, double-blind, placebo-controlled phase 3 studies, men and women with HIV-associated abdominal fat accumulation were randomly assigned (2:1 ratio) to receive tesamorelin for injection or placebo during the 26-week treatment phase. In the subsequent 26-week extension phase, patients who started on tesamorelin for injection were randomly assigned to continue receiving tesamorelin for injection or to switch to placebo, and patients who started on placebo were switched to tesamorelin for injection. In consultation with the FDA a decrease of ≥8% in excess visceral abdominal fat area was determined to be clinically significant and was used to define “responders,” as specified a priori in the data analysis plan. Post-hoc analyses were performed to assess differences between responders and non-responders.1

In this post-hoc analysis, responders were determined independently at 26 and 52 weeks. A per-protocol analysis of adherent patients (>80% compliance with daily tesamorelin injections) was used to analyze clinical effects of tesamorelin. The per-protocol population included patients who had no major protocol violations and underwent ≥1 post-dose abdominal CT scan for excess abdominal fat measurement. Responders were individuals whose CT scans showed ≥8% reduction in excess visceral abdominal fat from baseline.1

A post-hoc analysis of pooled data from two pivotal clinical trials of tesamorelin in HIV-infected patients with excess visceral abdominal fat was not part of NDA to support approval of EGRIFTA®. Although the results differentiate responders from non-responders, they were not reviewed and approved by the FDA. Caution should be exercised in interpreting the results of the analysis.
