Dosing

Advanced Renal Cell Carcinoma 25 mg administered as an intravenous infusion over a 30-60 minute period once weekly; continue until disease progression or unacceptable toxicity. Premedicate with IV diphenhydramine 25-50 mg approximately 30 minutes before each dose.

Dose Modification - Hepatic Impairment Reduce dose to 15 mg/week in patients with mild hepatic impairment (bilirubin >1-1.5x ULN or AST >ULN but bilirubin <=ULN); contraindicated if bilirubin >1.5x ULN.

Dose Modification - Strong CYP3A4 Inhibitors Avoid concomitant use; if unavoidable, reduce dose to 12.5 mg/week and allow approximately 1-week washout after inhibitor discontinuation before returning to prior dose.

Dose Modification - Strong CYP3A4 Inducers Avoid concomitant use; if unavoidable, increase dose from 25 mg/week up to 50 mg/week, then return to prior dose once inducer is discontinued.

Dose Modification - Toxicity Hold for ANC or platelet nadirs meeting threshold criteria or NCI CTCAE grade >=3 adverse reactions; once resolved to grade <=2, restart at dose reduced by 5 mg/week to no lower than 15 mg/week.

Metastasis from malignant neoplasm of colon and/or rectum 5 mg/kg IV every 2 weeks with bolus-IFL; 10 mg/kg IV every 2 weeks with FOLFOX4; 5 mg/kg IV every 2 weeks or 7.5 mg/kg IV every 3 weeks with fluoropyrimidine-irinotecan- or fluoropyrimidine-oxaliplatin-based chemotherapy after progression on a first-line bevacizumab product-containing regimen.

Non-Small Cell Lung Carcinoma 15 mg/kg IV every 3 weeks in combination with carboplatin and paclitaxel.

Glioblastoma 10 mg/kg IV every 2 weeks.

Renal Cell Carcinoma 10 mg/kg IV every 2 weeks in combination with interferon alfa.

Cervix carcinoma 15 mg/kg IV every 3 weeks in combination with paclitaxel and cisplatin or paclitaxel and topotecan.

Malignant neoplasm of ovary, Fallopian Tube Carcinoma, Primary Peritoneal Cancer Stage III/IV following initial surgical resection: 15 mg/kg IV every 3 weeks with carboplatin and paclitaxel for up to 6 cycles, followed by 15 mg/kg every 3 weeks as a single agent for up to 22 cycles. Platinum-resistant recurrent: 10 mg/kg IV every 2 weeks with paclitaxel, pegylated liposomal doxorubicin, or topotecan (weekly); or 15 mg/kg IV every 3 weeks with topotecan (every 3 weeks). Platinum-sensitive recurrent: 15 mg/kg IV every 3 weeks with carboplatin and paclitaxel or carboplatin and gemcitabine for 6-10 cycles, followed by 15 mg/kg every 3 weeks as a single agent.

Pharmacology

Temsirolimus binds to the intracellular protein FKBP-12, and the resulting protein-drug complex inhibits mTOR (mammalian target of rapamycin), blocking its ability to phosphorylate downstream effectors p70S6k and S6 ribosomal protein, leading to G1 growth arrest in tumor cells and reduced levels of HIF-1, HIF-2 alpha, and vascular endothelial growth factor.

Bevacizumab-bvzr binds VEGF and prevents its interaction with receptors Flt-1 and KDR on the surface of endothelial cells, inhibiting endothelial cell proliferation, new blood vessel formation, and metastatic disease progression.
