4 CONTRAINDICATIONS
HYFTOR is contraindicated in patients with a history of hypersensitivity to sirolimus or any other component of HYFTOR. Reactions to sirolimus have included anaphylactic/anaphylactoid reactions, angioedema, exfoliative dermatitis, and hypersensitivity vasculitis [see Warning and Precautions (5.1)] .
-
5 WARNINGS AND PRECAUTIONS
5.1 Hypersensitivity Reactions
Hypersensitivity reactions, including anaphylactic/anaphylactoid reactions, angioedema, exfoliative dermatitis, and hypersensitivity vasculitis have been associated with the oral administration of sirolimus. The concomitant use of HYFTOR with other drugs known to cause angioedema, such as angiotensin-converting enzyme (ACE) inhibitors, may increase the risk of developing angioedema. Elevated sirolimus levels (with or without concomitant ACE inhibitors) may also potentiate angioedema. Discontinue HYFTOR immediately if symptoms of hypersensitivity occur.
5.2 Serious Infection
Serious infections, including opportunistic infections, have been reported after oral administration of sirolimus. Cases of progressive multifocal leukoencephalopathy (PML), sometimes fatal have been reported in patients treated with oral sirolimus. Discontinue HYFTOR immediately if symptoms of infection occur.
5.3 Malignancy
Lymphoma and other malignancies, particularly of the skin, have been observed after oral administration of sirolimus. Patients should minimize or avoid exposure to natural or artificial sunlight (tanning beds or UVA/B treatment) while using HYFTOR. If patients need to be outdoors while using HYFTOR, they should wear protective clothing and discuss other sun protection measures with their physician.
5.4 Hyperlipidemia
Increased serum cholesterol and triglycerides requiring treatment have been observed with oral administration of sirolimus. Monitor for hyperlipidemia during treatment with HYFTOR.
5.5 Interstitial Lung Disease/Non-Infectious Pneumonitis
Cases of interstitial lung disease [ILD] (including pneumonitis, bronchiolitis obliterans organizing pneumonia [BOOP], and pulmonary fibrosis), some fatal, with no identified infectious etiology have occurred in patients receiving oral sirolimus. In some cases, the ILD has resolved upon discontinuation or dosage reduction of oral sirolimus. Discontinue HYFTOR immediately if symptoms of ILD occur.
5.6 Immunizations
During treatment with HYFTOR, vaccinations may be less effective. Complete all age-appropriate vaccinations as recommended by current immunization guidelines prior to initiating treatment with HYFTOR. The use of live vaccines should be avoided during treatment with HYFTOR.
5.7 Embryo-Fetal Toxicity
Based on animal studies and the mechanism of action, oral sirolimus can cause fetal harm when administered to a pregnant woman. In animal studies, oral sirolimus caused embryo-fetal toxicity when administered during the period of organogenesis at maternal exposures that were equal to or less than human exposures at the recommended lowest starting dose. HYFTOR is systemically absorbed after topical administration and may result in fetal exposure. Advise pregnant women of the potential risk to a fetus. Advise female patients of reproductive potential to avoid becoming pregnant. They should use effective contraception prior to, throughout treatment and for 12 weeks after the final dose of HYFTOR [see Use in Specific Populations (8.1, 8.3), Clinical Pharmacology (12.1, 12.3)].
5.8 Male Infertility
Azoospermia or oligospermia has been observed after oral administration of sirolimus [see Use in Specific Populations (8.3), Nonclinical Toxicology (13.1)]. Sirolimus is an anti-proliferative drug and affects rapidly dividing cells like the germ cells. Advise males that HYFTOR may impair fertility.

6 ADVERSE REACTIONS
6.1 Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
In a randomized, double-blind, vehicle-controlled trial, subjects aged 6 years and older with facial angiofibroma associated with tuberous sclerosis applied HYFTOR twice daily for 12 weeks. A total of 30 subjects were treated with HYFTOR and 32 with the vehicle. The majority of the subjects were female (54.8%). A total of 40.3% were less than 18 years of age.
The most common adverse reactions reported by ≥1% of subjects treated with HYFTOR and more frequently than in subjects treated with vehicle are presented in Table 1. Adverse reactions occurred with similar frequency in pediatric subjects 6 years of age and older.

8 USE IN SPECIFIC POPULATIONS
8.1 Pregnancy
Risk Summary
Based on animal studies and mechanism of action, oral sirolimus can cause fetal harm when administered to a pregnant woman. HYFTOR is systemically absorbed after topical administration and may result in fetal exposure. The available data from case reports on HYFTOR use in pregnant women are insufficient to evaluate for a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. Animal reproduction studies have not been conducted with HYFTOR. In an animal reproduction study, oral administration of 0.5 mg/kg/day sirolimus caused embryo-fetal lethality in pregnant rats when administered during the period of organogenesis (see Data). The available data do not allow the calculation of relevant comparisons between the systemic exposure of sirolimus observed in animal studies to the systemic exposure that would be expected in humans after topical use of HYFTOR.
The background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively.
Data
Animal Data
In embryo-fetal development studies in rats, oral administration of sirolimus to pregnant rats during the period of organogenesis (gestation days 6 -15) induced embryo-fetal lethality at 0.5 mg/kg/day, reduced fetal body weight at 1.0 mg/kg/day and caused maternal toxicity at 2.0 mg/kg/day. No treatment related embryo-fetal developmental effects were observed at 0.1 mg/kg/day.
In embryo-fetal development studies in rabbits, oral administration of sirolimus to pregnant rabbits during the period of organogenesis (gestation days 6 -18) induced maternal toxicity (decreased body weight) at 0.05 mg/kg/day, which was associated with embryo-fetal loss or early resorption. No treatment related developmental effects were observed at 0.025 mg/kg/day.
In a pre- and postnatal development toxicity study, oral administration of sirolimus to pregnant rats during gestation and lactation (gestation day 6 through lactation day 20) increased the incidence of dead pups, resulting in reduced live litter size at 0.5 mg/kg/day. No treatment related developmental effects were observed at 0.1 mg/kg/day.
Sirolimus did not cause maternal toxicity or affect developmental parameters in the surviving offspring (morphological development, motor activity, learning, or fertility assessment) at 0.5 mg/kg/day, the highest dose tested.
8.2 Lactation
Risk Summary
There are no available data on the presence of sirolimus in human milk, the effects on the breastfed infant, or the effects on milk production. After oral administration, sirolimus was present in the milk of lactating rats. Because of the potential for serious adverse reactions in the breastfed infant, breastfeeding is not recommended during treatment with HYFTOR.
8.3 Females and Males of Reproductive Potential
Contraception
Based on animal studies with oral sirolimus, HYFTOR may cause fetal harm when administered to pregnant women. Females of reproductive potential are recommended to avoid becoming pregnant and to use an effective contraceptive method. Effective contraception should be initiated before HYFTOR therapy and used throughout treatment and for 12 weeks after the final dose of HYFTOR [see Warnings and Precautions (5.7), Use in Specific Populations (8.1)] .
Infertility
Based on clinical findings and findings in animal studies, male and female fertility may be compromised by the treatment with sirolimus [see Warnings and Precautions (5.8), Nonclinical Toxicology (13.1)]. Ovarian cysts and menstrual disorders (including amenorrhea and menorrhagia) have been reported in females with the use of oral sirolimus. Azoospermia has been reported in males with the use of oral sirolimus and have been reversible upon discontinuation of sirolimus in most cases.
8.4 Pediatric Use
The safety and effectiveness of HYFTOR have been established in pediatric patients aged 6 years and older for the topical treatment of facial angiofibroma associated with tuberous sclerosis. Use of HYFTOR in this age group is supported by data from a randomized, vehicle-controlled, double-blind 12-week trial along with additional efficacy and long-term safety data from a 104-week open label safety trial. A total of 13 pediatric subjects aged 6 years to 17 years received HYFTOR in the Phase 3 clinical trial along with 48 pediatric subjects aged 3 years to 17 years in the 104-week open label safety trial. Adverse reactions occurred with similar frequency in adult and pediatric subjects [see Adverse Reaction (6.1), Clinical Studies (14)].
The safety and effectiveness of HYFTOR for this indication have not been established in pediatric patients less than 6 years of age.
8.5 Geriatric Use
Clinical studies of HYFTOR did not include sufficient numbers of subjects aged 65 years and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients.

-
12 CLINICAL PHARMACOLOGY
12.1 Mechanism of Action
The mechanism of action of sirolimus in the treatment of angiofibroma associated with tuberous sclerosis is unknown. Tuberous sclerosis is associated with genetic defects in TSC1 and TSC2 which leads to the constitutive activation of mammalian target of rapamycin (mTOR). Sirolimus inhibits mTOR activation.
12.3 Pharmacokinetics
Absorption
Following 12 weeks of treatment with HYFTOR in adult and pediatric subjects aged 6 years and older, sirolimus blood concentrations ranged from undetectable to 0.50 ng/mL after multiple doses of HYFTOR in the Phase 3 trial. Periodic blood samples were obtained in the 52-week trial and the maximum sirolimus concentration measured at any time in adult subjects was 3.27 ng/mL and the maximum sirolimus concentration measured at any time in pediatric subjects was 1.80 ng/mL.
Distribution
There was no evidence based on blood concentrations that sirolimus accumulates systemically upon topical application in patients with tuberous sclerosis for periods of up to 1 year.
Elimination
Metabolism
Studies evaluating the metabolism of HYFTOR have not been conducted.
Sirolimus is a substrate for both CYP3A4 and P-gp. Sirolimus is extensively metabolized after oral administration in the intestinal wall and liver and undergoes counter-transport from enterocytes of the small intestine into the gut lumen. Inhibitors of CYP3A4 and P-gp increase sirolimus concentrations. Inducers of CYP3A4 and P-gp decrease sirolimus concentrations. Sirolimus is extensively metabolized by O-demethylation and/or hydroxylation. Seven (7) major metabolites, including hydroxy, demethyl, and hydroxydemethyl, are identifiable in whole blood. Some of these metabolites are also detectable in plasma, fecal, and urine samples. Sirolimus is the major component in human whole blood and contributes to more than 90% of the immunosuppressive activity.
Excretion
Studies evaluating the excretion of HYFTOR have not been conducted.
After a single dose of [ 14C] sirolimus oral solution in healthy volunteers, the majority (91%) of radioactivity was recovered from the feces, and only a minor amount (2.2%) was excreted in urine. The mean ± SD terminal elimination half-life (t½) of sirolimus after multiple dosing in stable renal transplant patients was estimated to be about 62 ± 16 hours.
Drug Interaction Studies
Drug interaction studies with HYFTOR have not been conducted. Sirolimus is known to be a substrate for both cytochrome P-450 3A4 (CYP3A4) and p-glycoprotein (P-gp). [see Drug Interactions (7.1, 7.2)] .
-
13 NONCLINICAL TOXICOLOGY
13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility
Oral carcinogenicity studies were conducted in mice and rats. In an oral carcinogenicity study conducted in female mice, sirolimus administered once daily for 86 weeks was associated with a statistically significant increase in malignant lymphoma at all dose levels compared with control animals. In a second oral mouse carcinogenicity study, sirolimus-related hepatocellular adenoma and carcinoma were induced in male mice. In an oral carcinogenicity study conducted in rats with sirolimus there were no significant findings.
Sirolimus was not genotoxic in the in vitro bacterial reverse mutation assay, the Chinese hamster ovary cell chromosomal aberration assay, the mouse lymphoma cell forward mutation assay, or the in vivo mouse micronucleus assay.
Fertility was decreased in both male and female rats following oral administration of sirolimus 2.0 and 0.5 mg/kg, respectively. In male rats, atrophy of testes, epididymides, prostate, seminiferous tubules and/or reduced sperm counts were observed. In female rats, decreased ovarian and uterine weights and decreased implantation were observed. Testicular tubular degeneration was also seen in a 4-week intravenous study of sirolimus in monkeys at 0.1 mg/kg.
-
14 CLINICAL STUDIES
A single, randomized, double-blind, vehicle-controlled, multi-center, Phase 3 trial was conducted in Japan to evaluate HYFTOR for the treatment of adults and pediatric patients 6 years of age and older with facial angiofibroma associated with tuberous sclerosis (NCT02635789). A total of 62 Japanese subjects with 3 or more angiofibromas (≥2 mm in diameter with redness in each) on the face were enrolled in this trial. Overall, 28 subjects (45%) were male and 34 (55%) were female. A total of 25 subjects (40%) were between 6 and <18 years of age. In this trial, subjects applied either HYFTOR or vehicle twice daily to the skin of their face affected with angiofibroma for 12 weeks.
The efficacy was assessed by the investigator (live assessment) based on the composite improvement from baseline in size and redness of facial angiofibroma, using subjects' baseline photographs as reference. The proportion of subjects assessed as 'Improved' or 'Markedly Improved' at Week 12 is presented in Table 3. An assessment of 'Improved' was defined as at least a 50% reduction in the size and a 2-level reduction in redness and an assessment of 'Markedly Improved' was defined as at least a 75% reduction in the size and a 3-level reduction in redness.
