Chỉ định và Liều dùng
Advanced renal cell carcinoma
Adult: 25 mg once a week via infusion over 30-60 minutes. Continue until disease progression or unacceptable toxicity. Treatment interruption and/or dose reduction may be required if toxicity occurs. Premedication with antihistamine is recommended to prevent hypersensitivity reactions.

Mantle cell lymphoma
Adult: Relapsed or refractory type: 175 mg once a week for 3 weeks, then 75 mg once a week thereafter, given via infusion over 30-60 minutes. Treatment interruption and/or dose reduction may be required if absolute neutrophil count (ANC) falls below 1,000 cells/mm3 and platelet count is below 50,000 cells/mm3. Restart treatment with reduced dose as follows: if last dose is 175 mg, reduce to 75 mg; if last dose is 75 mg, reduce to 50 mg; if last dose is 50 mg, reduce to 25 mg. If neutrophil and platelet counts are not maintained at or above these levels on the new dose, treatment should be withheld and the next lower dose given once the counts have recovered. Premedication with antihistamine is recommended to prevent hypersensitivity reactions.
Nhóm bệnh nhân đặc biệt
Advanced renal cell carcinoma:
Patients taking strong CYP3A4 inhibitors: 12.5 mg once a week. If concomitant strong CYP3A4 inhibitor is discontinued, allow at least 1 week to elapse before increasing to the dose used prior to initiation of CYP3A4 inhibitor.
Patients taking strong CYP3A4 inducers: 50 mg once a week. If concomitant strong CYP3A4 inducer is discontinued, reduce to the dose used prior to initiation of CYP3A4 inducer.
Suy gan
Advanced renal cell carcinoma: Mild (bilirubin >1-1.5 x ULN or AST >ULN with bilirubin ≤ULN): Reduce dose to 15 mg once a week. Moderate to severe (bilirubin >1.5 x ULN): Contraindicated.

Mantle cell lymphoma:
Moderate to severe: Contraindicated.

Thông tin tư vấn bệnh nhân
Avoid exposure to sunlight or UV light.
Chỉ số theo dõi
Monitor CBC with differential and platelets weekly; serum glucose, cholesterol and triglycerides, renal and hepatic functions at baseline and during treatment; symptoms or radiographic changes of interstitial lung disease.
Tương tác
Decreased exposure with CYP3A4 inducers (e.g. rifampicin, carbamazepine, phenytoin). Increased exposure with CYP3A4 inhibitors (e.g. clarithromycin, ritonavir, ketoconazole). May increase the risk of intracerebral bleeding when given with anticoagulants. Concomitant use with sunitinib may result in dose-limiting toxicities. Increased risk of angioneurotic oedema with ACE inhibitors or Ca channel blockers.
Potentially Fatal: May diminish the therapeutic effect of live vaccines.
Tương tác với thức ăn
Increased plasma levels with grapefruit and grapefruit juice. Decreased plasma levels with St John’s wort.
Tác dụng
Description: Temsirolimus is an inhibitor of mammalian target of rapamycin (mTOR) kinase, a protein which controls cell division. It binds to the intracellular protein FKBP-12 to form a complex that inhibits the activation of mTOR, thus inhibiting angiogenesis and tumour cell proliferation, growth and survival.
Absorption: Time to peak plasma concentration: At end of infusion (temsirolimus); 0.5-2 hours after infusion (sirolimus).
Metabolism: Metabolised by CYP3A4 to sirolimus (major active metabolite) and 4 minor metabolites.
Excretion: Mainly via faeces (78%); via urine (approx 5%). Elimination half-life: Approx 17 hours (temsirolimus); approx 55 hours (sirolimus).
