SANCUSO- granisetron patch
Kyowa Kirin, Inc.
Sancuso® is indicated for the prevention of nausea and vomiting in adults receiving moderately and/or highly emetogenic chemotherapy regimens of up to 5 consecutive days duration.
The recommended dosage is a single transdermal system applied to the upper outer arm a minimum of 24 hours, up to a maximum of 48 hours, before chemotherapy. The transdermal system should be worn at minimum, 24 hours after chemotherapy is finished. The transdermal system can be worn for up to 7 days.
Application and Removal Instructions
- Each transdermal system releases 3.1 mg of granisetron per 24 hours for up to 7 days.
- Each transdermal system is packed in a pouch and should be applied directly after the pouch has been opened.
- Only wear one transdermal system at any time.
- Do not cut the transdermal system.
- Open the pouch and apply the transdermal system to clean, dry, nearly hairless, intact healthy skin on the upper outer arm.
- Do not place Sancuso transdermal system on skin that is red, irritated, or damaged.
- Do not apply a heat pad or heat lamp over or in vicinity of the transdermal system and avoid extended exposure to heat [see Warnings and Precautions (5.4)].
- Cover the application site of the transdermal system with clothing, if there is a risk of exposure to direct natural or artificial sunlight throughout the period of wear and for 10 days following its removal [see Warnings and Precautions (5.5)].
- After the transdermal system is applied, wash hands thoroughly.
- Remove the transdermal system by peeling off gently from the skin.
- Upon removal, fold the transdermal system in half with the sticky side together, and discard in the household trash in a manner that prevents accidental contact or ingestion by children, pets or others.
- Sancuso contains granisetron. Do not use other granisetron-containing products with Sancuso.
Transdermal System: a 52 cm2 thin, translucent, rectangular-shaped transdermal system with rounded corners imprinted on one side with “Granisetron 3.1 mg/24 hours”. The transdermal system releases 3.1 mg of granisetron per 24 hours for up to 7 days.
Sancuso is contraindicated in patients with known hypersensitivity to granisetron or to any of the components of the transdermal system [see Description (10)].
Sancuso may mask a progressive ileus and/or gastric distention. This should be particularly considered before use of Sancuso in patients who have had recent abdominal surgery. Monitor for decreased bowel activity, particularly in patients with risk factors for gastrointestinal obstruction.
The development of serotonin syndrome has been reported with 5-HT3 receptor antagonists. Most reports have been associated with concomitant use of serotonergic drugs (e.g., selective serotonin reuptake inhibitors (SSRIs), serotonin and norepinephrine reuptake inhibitors (SNRIs), monoamine oxidase inhibitors, mirtazapine, fentanyl, lithium, tramadol, and intravenous methylene blue). Some of the reported cases were fatal. Serotonin syndrome occurring with overdose of another 5-HT3 receptor antagonist alone has also been reported. The majority of reports of serotonin syndrome related to 5-HT3 receptor antagonist use occurred in a post- anesthesia care unit or an infusion center.
Symptoms associated with serotonin syndrome may include the following combination of signs and symptoms: mental status changes (e.g., agitation, hallucinations, delirium, and coma), autonomic instability (e.g., tachycardia, labile blood pressure, dizziness, diaphoresis, flushing, hyperthermia), neuromuscular symptoms (e.g., tremor, rigidity, myoclonus, hyperreflexia, incoordination), seizures, with or without gastrointestinal symptoms (e.g., nausea, vomiting, diarrhea). Patients should be monitored for the emergence of serotonin syndrome, especially with concomitant use of Sancuso and other serotonergic drugs. If symptoms of serotonin syndrome occur, discontinue Sancuso and initiate supportive treatment. Patients should be informed of the increased risk of serotonin syndrome, especially if Sancuso is used concomitantly with other serotonergic drugs. [see Drug Interactions (7)].
In clinical trials with Sancuso, application site reactions were reported that were generally mild in intensity and did not lead to discontinuation of use. The incidence of reactions was comparable with placebo.
If severe reactions, or a generalized skin reaction occur (e.g., allergic rash, including erythematous, macular, papular rash or pruritus), remove the Sancuso transdermal system.
Prolonged exposure to heat results in increasing plasma concentrations of granisetron during the period of heat exposure [see Clinical Pharmacology (12.3)]. Do not apply a heat pad or heat lamp over or in the vicinity of the Sancuso transdermal system and avoid extended exposure to heat [see Dosage and Administration (2)].
Granisetron may be affected by direct natural or artificial sunlight, including sunlamps. An in vitro study using Chinese hamster ovary cells suggests that granisetron has the potential for photogenotoxicity [see Nonclinical Toxicology (13.3)]. To avoid a potential skin reaction, advise patients to cover the application site of the transdermal system with clothing if there is a risk of exposure to direct natural or artificial sunlight throughout the period of wear and for 10 days following its removal.
The following are serious or otherwise clinically significant adverse reactions reported in other sections of labeling:
- Progressive ileus and gastric distention [see Warnings and Precautions (5.1)]
- Serotonin syndrome [see Warnings and Precautions (5.2)]
- Skin reactions [see Warnings and Precautions (5.3)]
- Increased drug exposure with use of external heat sources [see Warnings and Precautions (5.4)]
- Phototoxicity with ultraviolet light exposure [se Warnings and Precautions (5.5)]
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 clinical practice.
The safety of Sancuso was evaluated in a total of 404 patients undergoing chemotherapy who participated in two double-blind, comparator studies with transdermal system treatment durations of up to 7 days. The control groups included a total of 406 patients who received a daily dose of 2 mg oral granisetron, for 1 to 5 days.
Adverse reactions occurred in 9% (35/404) of patients receiving Sancuso and 7% (29/406) of patients receiving oral granisetron. The most common adverse reaction was constipation that occurred in 5% of patients in the Sancuso group and 3% of patients in the oral granisetron group.
Table 1 lists the adverse reactions that occurred in at least 3% of patients treated with Sancuso or oral granisetron.

5-HT3 receptor antagonists, such as granisetron, may be associated with arrhythmias or ECG abnormalities. Three ECGs were performed on 588 patients in a randomized, parallel group, double-blind, double-dummy study: at baseline before treatment, the first day of chemotherapy, and 5 to 7 days after starting chemotherapy. QTcF prolongation greater than 450 milliseconds was seen in a total of 11 (1.9%) patients after receiving granisetron, 8 (2.7%) on oral granisetron, and 3 (1.1%) on the transdermal system. No new QTcF prolongation greater than 480 milliseconds was observed in any patient in this study. No arrhythmias were detected in this study.
Adverse reactions reported in clinical trials with other formulations of granisetron include the following:
Gastrointestinal: abdominal pain, diarrhea, constipation, elevation of ALT and AST levels, nausea and vomiting
Cardiovascular: hypertension, hypotension, angina pectoris, atrial fibrillation and syncope have been observed rarely
Central Nervous System: dizziness, insomnia, headache, anxiety, somnolence and asthenia
Hypersensitivity: rare cases of hypersensitivity reactions, sometimes severe (e.g. anaphylaxis, shortness of breath, hypotension, urticaria) have been reported
Other: fever; events often associated with chemotherapy have also been reported: leucopenia, decreased appetite, anemia, alopecia, thrombocytopenia.
