What is Portrazza?

Necitumumab is an anti-EGFR recombinant human monoclonal antibody of the IgG1 kappa isotype that specifically binds to the ligand binding site of the human EGFR. Necitumumab has an approximate molecular weight of 144.8 kDa. Necitumumab is produced in genetically engineered mammalian NS0 cells.

PORTRAZZA is a sterile, preservative free, clear to slightly opalescent and colorless to slightly yellow solution. PORTRAZZA is available in single-dose vials for intravenous infusion following dilution. Each vial contains 800 mg PORTRAZZA in 50 mL (16 mg/mL).

Each mL contains necitumumab (16 mg), citric acid anhydrous (0.256 mg), glycine (9.984 mg), mannitol (9.109 mg), polysorbate 80 (0.1 mg), sodium chloride (2.338 mg), sodium citrate dihydrate (2.55 mg), and water for injection, pH 6.0.

How should I use Portrazza?

PORTRAZZA™ is indicated, in combination with gemcitabine and cisplatin, for first-line treatment of patients with metastatic squamous non-small cell lung cancer.

The recommended dose of PORTRAZZA is 800 mg administered as an intravenous infusion over 60 minutes on Days 1 and 8 of each 3-week cycle prior to gemcitabine and cisplatin infusion. Continue PORTRAZZA until disease progression or unacceptable toxicity.

What might happen if I take too much Portrazza?

There has been limited experience with PORTRAZZA overdose in human clinical trials.

The highest dose of PORTRAZZA studied clinically in a human dose-escalation Phase 1 study was 1000 mg once a week and once every other week. Two out of 9 patients in the every other week cohort experienced dose-limiting toxicities (e.g., a combination of Grade 3 headache, vomiting, and nausea). There is no known antidote for PORTRAZZA overdose.

How should I store and handle Portrazza?

Store vials in a refrigerator at 2° to 8°C (36° to 46°F) until time of use. Keep the vial in the outer carton in order to protect from light. DO NOT FREEZE OR SHAKE the vial.

Clinical Pharmacology

Necitumumab is a recombinant human lgG1 monoclonal antibody that binds to the human epidermal growth factor receptor (EGFR) and blocks the binding of EGFR to its ligands. Expression and activation of EGFR has been correlated with malignant progression, induction of angiogenesis, and inhibition of apoptosis. Binding of necitumumab induces EGFR internalization and degradation in vitro. In vitro, binding of necitumumab also led to antibody-dependent cellular cytotoxicity (ADCC) in EGFR-expressing cells.

In in vivo studies using xenograft models of human cancer, including non-small cell lung carcinoma, administration of necitumumab to implanted mice resulted in increased antitumor activity in combination with gemcitabine and cisplatin as compared to mice receiving gemcitabine and cisplatin alone.

Non-Clinical Toxicology

Cabergoline should not be administered concurrently with D-antagonists, such as phenothiazines, butyrophenones, thioxanthenes, or metoclopramide.

Cardiopulmonary arrest or sudden death occurred in 15 (3%) of 538 patients treated with PORTRAZZA plus gemcitabine and cisplatin as compared to 3 (0.6%) of 541 patients treated with gemcitabine and cisplatin alone in Study 1. Twelve of the fifteen patients died within 30 days of the last dose of PORTRAZZA and had comorbid conditions including history of coronary artery disease (n=3), hypomagnesemia (n=4), chronic obstructive pulmonary disease (n=7), and hypertension (n=5). Eleven of the 12 patients had an unwitnessed death. Patients with significant coronary artery disease, myocardial infarction within 6 months, uncontrolled hypertension, and uncontrolled congestive heart failure were not enrolled in Study 1. The incremental risk of cardiopulmonary arrest or sudden death in patients with a history of coronary artery disease, congestive heart failure, or arrhythmias as compared to those without these comorbid conditions is not known.

Closely monitor serum electrolytes, including serum magnesium, potassium, and calcium prior to each infusion of PORTRAZZA during treatment and after PORTRAZZA administration for at least 8 weeks after the last dose. Withhold PORTRAZZA for Grade 3 or 4 electrolyte abnormalities; subsequent cycles of PORTRAZZA may be administered in these patients once electrolyte abnormalities have improved to Grade ≤2. Replete electrolytes as medically appropriate .
