Clinical
Sirolimus (with albumin) injection is used to treat a certain type of epithelioid cell tumor (soft tissue cancer that can form in any part of the body). Sirolimus is in a class of medications called kinase inhibitors. It works by blocking the action of the abnormal protein that tells the cancer cells to multiply. This may help slow the growth of tumors.

Availability & generic status
We did not find an FDA-approved generic match for this exact strength, form and route. Patent/protection dates below may affect future generic timing.
Why the date isn’t exact: Generic timing can change because patents may be challenged, settled, licensed, added, removed, or worked around with a narrower label — and FDA approval does not always mean a pharmacy can get the generic today.
🛈 What do these terms mean?
- Patent
- Legal protection listed in the Orange Book that may delay generic approval or launch. Issued by the U.S. Patent & Trademark Office.
- Substance patent
- Covers the active drug molecule itself — the hardest to design around. A generic generally can’t launch until it expires.
- Formulation (product) patent
- Covers a specific formulation or dosage form. A generic can sometimes work around it with a different formulation.
- Method-of-use patent
- A patent covering one specific approved use of the drug — not necessarily the whole molecule. A generic can sometimes launch with a “skinny label” that carves out the protected use and keeps the others.
- Skinny label
- A generic label that omits a still-patented use when the FDA allows it — letting a generic reach the market for the unprotected uses.
- Exclusivity
- FDA-granted marketing protection, separate from patents — e.g. 5-yr new chemical entity, 7-yr orphan drug, or a +6-month pediatric extension.
- Paragraph IV
- A generic applicant’s formal challenge to a listed patent. It can potentially lead to earlier generic entry, but often involves litigation or a settlement.
- RLD / RS
- Reference Listed Drug — the brand product the FDA uses as the reference for generic applications. Reference Standard — the product the FDA expects generics to compare against in bioequivalence testing.
- TE / AB rating
- FDA therapeutic-equivalence rating. An AB rating generally means the FDA considers a generic therapeutically equivalent to — and substitutable for — the brand.
- LOE (loss of exclusivity)
- The latest patent or exclusivity currently listed — the loss-of-exclusivity / latest-listed-protection date shown on this page. Paragraph-IV challenges and settlements can move the real date earlier; FDA approval and a manufacturer’s decision to market can move it later.
Built from the FDA Orange Book. The bars above are scaled to each protection’s expiry; the red LOE marker is the last one to lapse.

6.1Clinical 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. The safety of FYARRO was assessed in a single-arm study (AMPECT). Thirty-four patients received FYARRO 100 mg/m 2 on Days 1 and 8 of 21-day cycles until disease progression or unacceptable toxicity [see Clinical Studies ( 14.1 )] .
Among the 34 patients who received FYARRO, 16 (47%) were exposed for 6 months or longer and 7 (21%) were exposed for greater than 1 year. The median age of patients who received FYARRO was 59.5 years (range 27 to 78 years), 82% were female and Eastern Cooperative Oncology Group (ECOG) Performance Status was 0 (76%) or 1 (24%). Race was 71% White, 9% Black, 9% Asian, 3% Hawaiian/Pacific Islander and 9% Other/Not Reported.
Ethnicity was 82% not Hispanic or Latino, 15% Hispanic or Latino, and 3% Not Reported. Serious adverse reactions occurred in 14 (41%) patients who received FYARRO. Serious adverse reactions in >5% of patients, including 4 (12%) patients with infection and 2 (6%) patients each with abdominal pain, dehydration, and upper gastrointestinal hemorrhage.
Fatal adverse reactions occurred in 1 (2.9%) patient who received FYARRO and experienced upper gastrointestinal hemorrhage. Permanent discontinuation of FYARRO due to an adverse reaction occurred in 3 (9%) patients. Adverse reactions which resulted in permanent discontinuation of FYARRO included pneumonitis, anemia, and noninfective cystitis.
Dosage interruptions of FYARRO due to an adverse reaction occurred in 22 (65%) patients. Adverse reactions which required dosage interruption in >5% of patients included stomatitis in 6 (18%) patients, pneumonitis in 5 (15%) patients, anemia in 3 (9%) patients, and dehydration, dermatitis acneiform, and thrombocytopenia in 2 (6%) patients each. Dose reductions of FYARRO due to an adverse reaction occurred in 12 (35%) patients.
Adverse reactions which required dose reductions in >5% of patients included stomatitis and pneumonitis in 3 (9%) patients each. The most common adverse reactions (≥30%) were stomatitis in 27 (79%) patients, fatigue and rash in 23 (68%) patients each, infection in 20 (59%) patients, nausea and edema in 17 (50%) patients each, diarrhea, musculoskeletal pain and decreased weight in 16 (47%) patients each, decreased appetite in 15 (44%) patients, cough in 12 (35%) patients, and vomiting and dysgeusia in 11 (32%) patients each.

🔄 Drug Interactions ▾
7 DRUG INTERACTIONS Strong CYP3A4 and/or P-gp Inhibitors or Inducers : Avoid concomitant use. ( 2.3 , 7.1 ) Moderate or Weak CYP3A4 Inhibitors : Reduce FYARRO dose. ( 2.3 , 7.1 )
7.1Effects of Other Drugs on FYARRO CYP3A4 and/or P-gp Inhibitors or Inducers CYP3A4 and/or P-gp inhibitors may increase sirolimus concentrations, which may increase the risk of FYARRO adverse reactions. CYP3A4 and/or P-gp inducers may decrease sirolimus concentrations, which may reduce FYARRO effectiveness. Strong CYP3A4 and/or P-gp Inhibitors or Inducers: Avoid concomitant use of FYARRO with strong CYP3A4 and/or P-gp inhibitors or strong CYP3A4 and/or P-gp inducers [see Dosage and Administration ( 2.3 ), Clinical Pharmacology ( 12.3 )] .
Grapefruit or Grapefruit Juice: Avoid concomitant use of FYARRO with grapefruit or grapefruit juice. Moderate or Weak CYP3A4 Inhibitors: Reduce the dosage of FYARRO when used concomitantly with a moderate or weak CYP3A4 inhibitor [see Dosage and Administration ( 2.3 ), Clinical Pharmacology ( 12.3 )] . Moderate or Weak CYP3A4 Inducers: Use of FYARRO may result in decreased effectiveness.
👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS Hepatic Impairment : Reduce the dose of FYARRO in patients with mild or moderate hepatic impairment. Avoid use in patients with severe hepatic impairment. ( 2.4 , 8.6 ) Lactation : Advise not to breastfeed. ( 8.2 ) Females and Males of Reproductive Potentia l: May impair fertility in females and males. ( 5.9 , 5.10 , 8.3 )
8.1Pregnancy Risk Summary Based on animal studies and the mechanism of action, FYARRO can cause fetal harm when administered to a pregnant woman [see Clinical Pharmacology ( 12.1 )] . Although there are no data on the use of FYARRO in pregnant women, there are limited data on the use of sirolimus during pregnancy. In animal studies, oral sirolimus was embryo/fetotoxic in rats [see Data ] at sub-therapeutic doses.
Advise pregnant women of the potential risk to a fetus. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively.
Data Animal Data Reproductive studies in animals have not been performed with FYARRO. Studies with an oral formulation of sirolimus have shown that it crosses the placenta and is toxic to the conceptus. In rat embryo-fetal development studies, pregnant rats were administered an oral formulation of sirolimus during the period of organogenesis (Gestational Day 6-15).
Sirolimus produced embryo-fetal lethality at 0.5 mg/kg and reduced fetal weight at 1 mg/kg. The no observed adverse effect level (NOAEL) for fetal toxicity in rats was 0.1 mg/kg. Maternal toxicity (weight loss) was observed at 2 mg/kg.
The NOAEL for maternal toxicity was 1 mg/kg. In rabbit embryo-fetal development studies, pregnant rabbits were administered an oral formulation of sirolimus during the period of organogenesis (Gestational Day 6-18). There were no effects on embryo-fetal development at doses up to 0.05 mg/kg; however, at doses of 0.05 mg/kg and above, the ability to sustain a pregnancy was impaired (i.e., embryo-fetal abortion or early resorption).
Maternal toxicity (decreased body weight) was observed at 0.05 mg/kg. The NOAEL for maternal toxicity was 0.025 mg/kg. In a pre- and post-natal development study in rats, pregnant females were dosed with an oral formation of sirolimus during gestation and lactation (Gestational Day 6 through Lactation Day 20).
An increased incidence of dead pups occurred at 0.5 mg/kg, resulting in reduced live litter size. At 0.1 mg/kg, there were no adverse effects on offspring. Sirolimus did not cause maternal toxicity or affect developmental parameters in the surviving offspring (e.g., morphological development, motor activity, learning, or fertility assessment) at 0.5 mg/kg, the highest oral dose tested.
8.2Lactation Risk Summary There are no data on the presence of FYARRO in human milk or its effects on the breastfed child or on milk production. It is not known whether sirolimus is present in human milk. There are no data on its effects on the breastfed infant or milk production.
The pharmacokinetic and safety profiles of sirolimus in infants are not known. Sirolimus is present in the milk of lactating rats. There is potential for serious adverse effects from sirolimus in breastfed infants based on mechanism of action [see Clinical Pharmacology ( 12.1 )] .
Because of the potential for serious adverse reactions in breastfed infants from FYARRO, advise women not to breastfeed during treatment with FYARRO and for 2 weeks after the last dose.
8.3Females and Males of Reproductive Potential FYARRO can cause fetal harm when administered to a pregnant woman [see Warnings and Precautions ( 5.9 ), Use in Specific Populations ( 8.1 )]. Pregnancy Testing Verify pregnancy status of females of reproductive potential prior to initiating FYARRO. Contraception Females Advise females of reproductive potential to use effective contraception during… [Excerpted — this section continues on DailyMed.]

🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Sirolimus in FYARRO is an inhibitor of mechanistic target of rapamycin kinase (mTOR, previously known as mammalian target of rapamycin). mTOR, a serine threonine kinase, is downstream of the PI3K/AKT pathway, controls key cellular processes such as cell survival, growth, and proliferation, and is commonly dysregulated in several human cancers. In cells, sirolimus binds to the immunophilin, FK Binding Protein-12 (FKBP-12), to generate an immunosuppressive complex. The sirolimus-FKBP-12 complex binds to and inhibits activation of the mechanistic target of rapamycin complex 1 (mTORC1).
Inhibition of mTOR by sirolimus has been shown to reduce cell proliferation, angiogenesis, and glucose uptake in in vitro and in vivo studies. In a nonclinical study in athymic mice bearing human tumor xenografts, intravenous administration of FYARRO resulted in higher tumor accumulation of sirolimus, inhibition of an mTOR target in the tumor, and tumor growth inhibition compared to administration of an oral formulation of sirolimus at the same weekly total dose.
12.2Pharmacodynamics Sirolimus exposure-response relationship has not been fully characterized. Cardiac Electrophysiology The effect of FYARRO on the QTc interval has not been adequately characterized.
12.3Pharmacokinetics Absorption Following administration of FYARRO at the recommended dosage, the estimated mean (%CV) C max and AUC 0-inf of sirolimus in patients with advanced solid tumors were 2590 ng/mL (30% CV) and 22100 ng∙h/mL (50% CV), respectively. Distribution The protein binding of sirolimus is >99%, primarily to serum albumin in vitro . Elimination The mean elimination half-life of sirolimus is approximately 59 hours (41% CV).
Metabolism Sirolimus is metabolized by CYP3A4. Excretion Following a single radiolabeled sirolimus oral dose to human subjects, 91% and 2% of the radioactivity was recovered in feces and urine, respectively. Specific Populations There were no clinically significant differences in the pharmacokinetics of sirolimus based on age (18 to 78 years), sex, mild or moderate renal impairment (creatinine clearance 30 to 89 mL/min).
The effect of race, severe renal impairment, and hepatic impairment on the pharmacokinetics of sirolimus is unknown. Drug Interaction Studies No studies evaluating the drug interaction potential of FYARRO have been conducted. Sirolimus is a substrate for both CYP3A4 and P-gp.

📋 Description ▾
11 DESCRIPTION FYARRO (sirolimus protein-bound particles for injectable suspension) (albumin-bound) is sirolimus formulated as albumin-bound nanoparticles. The active ingredient in FYARRO is sirolimus bound to albumin which exists in the nanoparticles in a non-crystalline, amorphous state. Sirolimus is a mechanistic target of rapamycin kinase (mTOR) inhibitor.
Sirolimus is a macrocyclic lactone produced by Streptomyces hygroscopicus . The chemical name of sirolimus is [3S[3R*[S*(1R*,3S*,4S*)),6S*,7E,9S*,10S*,12S*,14R*,15E,17E,19E,21R*,23R*,26S*, 27S*,3 4aR*]]-9,10,12,13,14,21,22,23,24,25,26,27,32,33,34,34a-Hexadecahydro-9,27-dihydroxy 3-[2-(4-hydroxy-3-methoxycyclohexyl)-1-methylethyl]-10,21-dimethoxy-6,8,12,14,20,26-hexamethyl-23,27-epoxy-3H-pyrido[2,1-c][1,4]oxaazacyclohentriacontine-1,5,11,28,29(4H,6H,31H)-pentone. Its empirical formula is C 51 H 79 NO 13 , and the molecular weight is 914.2.
The structural formula of sirolimus is illustrated as follows: Sirolimus is a white to off-white crystalline powder and is insoluble in water but freely soluble in benzyl alcohol, chloroform, acetone, and acetonitrile. FYARRO is supplied as a white to yellow, sterile, lyophilized powder for reconstitution with 20 mL of 0.9% Sodium Chloride Injection, USP prior to intravenous infusion. Each single-dose vial contains 100 mg of sirolimus (bound to human albumin) and approximately 850 mg of human albumin (containing sodium caprylate and sodium acetyltryptophanate).
Each milliliter (mL) of reconstituted suspension contains 5 mg sirolimus formulated as albumin-bound particles. Figure

14 CLINICAL STUDIES
14.1Perivascular Epithelioid Cell Tumor (PEComa) The efficacy of FYARRO was assessed in AMPECT (NCT02494570), a multi-center, single-arm clinical trial in 31 patients with locally advanced unresectable or metastatic malignant PEComa. Patients were required to have measurable disease at baseline, centrally confirmed diagnosis by pathology of malignant PEComa, and Eastern Cooperative Oncology Group (ECOG) Performance Status (PS) of 0 or 1. Patients with lymphangioleiomyomatosis and prior treatment with a mTOR inhibitor were excluded.
Patients received FYARRO at a dose of 100 mg/m 2 on Days 1 and 8 of 21-day cycles until disease progression or unacceptable toxicity. The efficacy population of 31 patients had the following demographic characteristics: median age 60 years (range 34 to 78), 81% female, 74% White, 10% Black, and 81% ECOG PS of 0. Five (16%) patients had locally advanced disease and 26 (84%) had metastatic disease.
Ninety-four percent of patients had prior surgery,19% had prior radiation therapy, and 13% had prior systemic therapy. The major efficacy outcome measures were overall response rate (ORR) and duration of response (DOR) as assessed by blinded independent central review (BICR) using RECIST v.1.1. The efficacy results are summarized in Table 6 .

🧪 Nonclinical Toxicology ▾
13 NONCLINICAL TOXICOLOGY
13.1Carcinogenesis, Mutagenesis, Impairment of Fertility No carcinogenicity, mutagenesis, or fertility studies were conducted with FYARRO. Carcinogenicity studies have been conducted in mice and rats with an oral formulation of sirolimus. In an 86-week female mouse study, there was a statistically significant increase in malignant lymphoma at all dose levels compared with controls.
In a second mouse study, hepatocellular adenoma and carcinoma in males were considered sirolimus-related. In a 104-week rat study, there were no significant findings. Sirolimus was not genotoxic in an in vitro bacterial reverse mutation assay, a Chinese hamster ovary cell chromosomal aberration assay, a mouse lymphoma cell forward mutation assay, or an in vivo mouse micronucleus assay.
When female rats were treated by gavage with an oral formulation of sirolimus and mated to untreated males, female fertility was decreased at 0.5 mg/kg due to decreased implantation. In addition, reduced ovary and uterus weight were observed. The NOAEL for female rat fertility was 0.1 mg/kg.
When male rats were treated by gavage with an oral formulation of sirolimus and mated to untreated females, male fertility was decreased at 2 mg/kg. Atrophy of testes, epididymides, prostate, seminiferous tubules, and reduced sperm counts were observed. The NOAEL for male rat fertility was 0.5 mg/kg.
Testicular tubular degeneration was also seen in a 4-week intravenous study of sirolimus in monkeys at 0.1 mg/kg.
