Bevacizumab dosing
(Avastin) VEGF inhibitor, 10mg/kg D1, D15 q28d OR 15mg/kg q21d
Infuse over 90min first time, then over 60min if tolerated.
Only PARPi to cross blood-brain barrier
Niraparib (Zejula)
Bevacizumab adverse effects
HTN (25%), hoarse voice, sore throat, bloody nose, GI (N/V/D), bowel perf (1-2% for ovarian, 2-3% for cervix d/t radiation), poor wound healing, VTE, PRES (rare), proteinuria (nephrotic syndrome), ovarian failure, change in taste perception, fistula (especially cervix), epistaxis, gingivitis
When do you need to hold avastin for proteinuria?
If >2+ protein on urine dip, get a 24hr urine protein. If >2g, hold avastin. Can restart once normalizes.
Describe MOA of bevacizumab.
Monoclonal antibody, VEGF inhibitor, inhibits angiogenesis.
VEGF-A interacts with receptor on epithelial cells (VEFG-R2). Bev binds VEGF-A extracellularly, making it unable to activate the receptor.
Absolute contraindications to bevacizumab
surgery within 28 days (especially abdominal or bowel), nephrotic syndrome, existing fistula or wound complication
Indications to discontinue bevacizumab
fistula, bowel perf, heart failure, hemorrhage, HTN crisis, PRES, VTE
Why does a dentist need to know if patient is on avastin?
May need to be held if planning invasive dental work
Zometa (zoledronic acid) use and dosage in oncology?
Bisphosphonate
Bone metastases - 4mg q 3-4wks
Hypercalcemia of malignancy - 4mg IV, q7d as needed if corrected Ca>12
MOA zometa
Inhibits bone resorption by inhibiting osteoclast activity, inhibits skeletal calcium release induced by tumors, decreases serum Ca and Phos and increases their elimination
Nivolumab/opdivo
Anti-PD1 monoclonal antibody, immune checkpoint inhibitor.
Binds PD1 receptor, blocking PDL1/2 from binding. Negative PD1 signaling that regulates T-cell activation and proliferation is disrupted causing release of PD1 mediated inhibition of immune response, including antitumor immune response.
(PDL1 normally binds PD1 to inhibit Tcell from killing tumor cell).
Nivolumab dosing
240mg q2 weeks
480mg q4 weeks
May be weight-based dosing if in combination with other agents
Nivolumab AEs
Infusion reaction, dermatologic tox, colitis, hyper/hypothyroidism, adrenal insufficiency, pulmonary toxicity, myocarditis, encephalitis, nephritis
Adverse rxn: give corticosteroids, hold or DC
