TORISEL must be administered under the supervision of a physician experienced in the use of antineoplastic medicinal products.
The vial of TORISEL concentrate must first be diluted with 1.8 ml of diluent withdrawn from the supplied vial to achieve a concentration of temsirolimus of 10 mg/ml. Withdraw the required amount of the temsirolimus-diluent mixture ( 10 mg/ml) and then inject rapidly into sodium chloride 9 mg/ml (0.9%) solution for injection.
For instructions on preparation and to help ensure correct dosing, see section 6.6.
Posology
Patients should be given intravenous diphenhydramine 25 to 50 mg (or similar antihistamine) approximately 30 minutes before the start of each dose of temsirolimus.
Treatment with TORISEL should continue until the patient is no longer clinically benefiting from therapy or until unacceptable toxicity occurs. No special dose modification is required for any of the populations that have been studied (gender, elderly).
Renal cell carcinoma
The recommended dose of temsirolimus for advanced renal cell carcinoma administered intravenously is 25 mg infused over a 30- to 60-minute period once weekly (see section 6.6 for instructions on dilution, administration and disposal).
Management of suspected adverse reactions may require temporary interruption and/or dose reduction of temsirolimus therapy. If a suspected reaction is not manageable with dose delays, then temsirolimus may be reduced by 5 mg/week decrements.
Mantle cell lymphoma
The recommended dosing regimen of temsirolimus for mantle cell lymphoma is 175 mg, infused over a 30-60 minute period once weekly for 3 weeks followed by weekly doses of 75 mg, infused over a 30-60 minute period. The starting dose of 175 mg was associated with a significant incidence of adverse events and required dose reductions/delays in the majority of patients. The contribution of the initial 175 mg doses to the efficacy outcome is currently not known.
Management of suspected adverse reactions may require temporary interruption and/or dose reduction of temsirolimus therapy according to the guidelines in the following tables. If a suspected reaction is not manageable with dose delays and/or optimal medical therapy, then the dose of temsirolimus should be reduced according to the dose reduction table below.
