CLINICAL RATIONALE

Tuberous Sclerosis Complex(2-5)

Tuberous sclerosis complex (TSC) is an autosomal dominant genetic disorder caused by a mutation in either the TSC1 gene or the TSC2 gene. TSC is characterized by the development of a variety of benign tumors in multiple organs, including the brain, heart, skin, eyes, kidney, lung, and liver. Seizures are the most frequent presenting neurologic feature of TSC, with more than 80% of patients developing seizures during childhood. Facial angiofibromas, the most obvious cutaneous manifestation of TSC, appear as innumerable pink papules that progressively enlarge and multiply over time. The lesions, which are highly visible markers of disease, may spontaneously bleed, impair vision, and cause emotional distress. 

International guidelines for TSC recommend a detailed skin examination at the time of diagnosis and annually thereafter. There is no significant risk of malignant transformation of skin lesions associated with RSC. When not prominent, the skin lesions do not require treatment. However, closer surveillance and intervention is recommended for skin lesions that rapidly change in size or number, and for those that cause pain, bleeding, functional impairment, or social problems.

Procedures to improve the appearance of skin lesions include dermabrasion, laser therapy, or surgical removal (excision) of a lesion. These procedures are not effective, however, in preventing early lesions and therefore have less than satisfactory outcomes. Sirolimus topical gel is FDA approved for the treatment of facial angiofibroma associated with TSC in patients age 6 years and older. Although there is rapid response in practically all patients, the possibility of recurrence is quite high. For severely disfiguring facial angiofibromas, a combination of laser therapy or dermabrasion in conjunction with topical sirolimus can be very useful. 

Efficacy(1)

Tuberous sclerosis complex (TSC) is associated with genetic defects in the TSC1 and TSC2 genes which results in overactivation of the mTOR pathway and benign tumor formation in multiple organs. Sirolimus inhibits mTOR activation. 

A single, randomized, double-blind, vehicle-controlled, multicenter, Phase 3 trial evaluated Hyftor for the treatment of adults and pediatric patients 6 years of age and older with facial angiofibroma associated with TSC. 

Safety(1)

HYFTOR is contraindicated in patients with a history of hypersensitivity to sirolimus or any other component of HYFTOR.
