Approval of Sculptra for Treating Facial Lipoatrophy
August 3, 2004
The Food and Drug Administration today, August 3, 2004, approved Sculptra, an injectable filler to correct facial fat loss in people with human immunodeficiency virus (HIV).
Sculptra is the first such treatment approved for a condition known as lipoatrophy, or facial wasting, a sinking of the cheek, eye and temple areas of the face caused by the loss of fat tissue under the skin which can affect HIV patients. FDA expedited review of the product because of its importance in treating people living with AIDS.
Sculptra is an injectable form of poly-L-lactic acid, a biodegradable, biocompatible synthetic polymer from the alpha-hydroxy-acid family that has been widely used for many years in dissolvable stitches, bone screws and facial implants.
FDA approval of Sculptra was based on data from four studies, totaling 277 HIV-positive patients with severe facial lipoatrophy. The patients, who were all being treated with antiretroviral drugs, were primarily white males, mostly ages 41 to 45. Patients were given three to six injections of Sculptra at two-week intervals and were followed for two years.
Skin thickness measurements and serial photographs from clinical studies were assessed, as well as other data submitted by the manufacturer, Dermik Laboratories, of Berwyn, Pa. Analysis indicated that the product significantly improved facial appearance, and was safe for restoration and/or correction of shape and contour deficiencies resulting from facial fat loss in patients with HIV/AIDS. Sculptra was shown to produce significant increases in dermal thickness (up to 2 to 3 times baseline values), adding volume to facial tissue and restoring shape to areas of the face with fat loss.
After an initial treatment series, repeat treatments may be needed to maintain the correction.
Most adverse events were related to the injection itself and included nodules, redness, swelling and bruising in the injection area.
The studies also demonstrated significant improvement in quality of life, and measures of anxiety and depression, conditions which can be associated with lipoatrophy.
Sculptra should only be used in patients with HIV by health care providers who are fully familiar with the product training materials provided by Dermik and the entire product package insert. The use of the product for other indications, such as to treat wrinkles, has not been approved by FDA.
Sculptra should not be used in anyone who is allergic to any of the product's components.
As a condition of approval, Dermik has agreed to conduct an open-label registry study of 100 patients for five years to evaluate Sculptra's long-term safety. The study will include at least 30 females and 30 people with dark skin types.
