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.

Q

Why does a dentist need to know if patient is on avastin?

A

May need to be held if planning invasive dental work

17
Q

Zometa (zoledronic acid) use and dosage in oncology?

A

Bisphosphonate
Bone metastases - 4mg q 3-4wks
Hypercalcemia of malignancy - 4mg IV, q7d as needed if corrected Ca>12

18
Q

MOA zometa

A

Inhibits bone resorption by inhibiting osteoclast activity, inhibits skeletal calcium release induced by tumors, decreases serum Ca and Phos and increases their elimination

19
Q

Nivolumab/opdivo

A

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).

20
Q

Nivolumab dosing

A

240mg q2 weeks
480mg q4 weeks
May be weight-based dosing if in combination with other agents

21
Q

Nivolumab AEs

Infusion reaction, dermatologic tox, colitis, hyper/hypothyroidism, adrenal insufficiency, pulmonary toxicity, myocarditis, encephalitis, nephritis

Adverse rxn: give corticosteroids, hold or DC
