Adverse Reactions

Nimotuzumab has been found to be very well tolerated in most clinical trials.

Adverse reactions seen in 58% of patients in a Phase I trial after a single dose of 50 to 400 mg of Nimotuzumab included:

Tremors
Fever
Nausea and vomiting
Dryness of mouth
Asthenia
Hypertension
Flushing

All adverse events were mild to moderate and were considered infusion reactions. No patient developed acne-form rash or other dermatological toxicity. (Crombet et al. 2004) Similar adverse event profile was seen in further clinical trials with Nimotuzumab. Grade 3 somnolence was reported in one patient following a 400 mg dose of Nimotuzumab. (Crombet et al. 2003)

In a Phase II trial, the most common adverse reactions were fever (4.28%), dizziness and hypotension (2.86%) and mild skin rash (1.43%). (Guozhen X, Li G , 2004) One case of anaphylactic reaction with skin rash requiring discontinuation of therapy was seen in a phase II clinical trial. (Clinigene International, 2006).

These adverse reactions respond to treatment with conventional doses of analgesics and antihistamines.
