Mvasi Drug Interactions

Effect of antineoplastic agents on bevacizumab pharmacokinetics: No clinically relevant pharmacokinetic interaction of co-administered chemotherapy on bevacizumab pharmacokinetics has been observed based on the results of a population PK analysis.
There was neither statistical significance nor clinically relevant difference in clearance of bevacizumab in patients receiving bevacizumab monotherapy compared to patients receiving bevacizumab in combination with interferon alfa 2a or other chemotherapies (IFL, 5-FU/LV, carboplatin/paclitaxel, capecitabine, doxorubicin or cisplatin/gemcitabine).
Effect of bevacizumab on the pharmacokinetics of other antineoplastic agents: No clinically relevant interaction of bevacizumab was observed on the pharmacokinetics of co-administered interferon-alfa 2a, or the chemotherapies irinotecan (and its active metabolite SN38), capecitabine, oxaliplatin (as determined by measurement of free and total platinum), and cisplatin. Conclusions on the impact of bevacizumab on gemcitabine pharmacokinetics cannot be drawn.
Combination of bevacizumab and sunitinib malate: In two clinical studies of metastatic renal cell carcinoma, microangiopathic haemolytic anaemia (MAHA) was reported in 7 of 19 patients treated with bevacizumab (10 mg/kg every two weeks) and sunitinib malate (50 mg daily) combination.
MAHA is a haemolytic disorder which can present with red cell fragmentation, anaemia, and thrombocytopenia. In addition, hypertension (including hypertensive crisis), elevated creatinine, and neurological symptoms were observed in some of these patients. All of these findings were reversible upon discontinuation of bevacizumab and sunitinib malate (see General: Hypertension, Proteinuria, Posterior Reversible Encephalopathy Syndrome (PRES) under Precautions).
Radiotherapy: The safety and efficacy of concomitant administration of radiotherapy and bevacizumab has not been established.
