History of another malignancy within 5 years of protocol entry, with the exception of
localized carcinomas cured by surgical resection such as basal cell carcinoma, stage I
breast or bladder cancer, or in situ carcinoma of the cervix.

Significant allergy history: these criteria will be assessed via the Allergy History CRF
Patients with any of the following concurrent conditions are not eligible:
No history of positive allergy tests to insect venoms (either skin or RAST).
No history of seasonal or recurrent asthma within the preceding 10 years.
No asthmatic symptoms (e.g. wheezing) related to a current respiratory tract infection.
No anaphylactic/anaphylactoid-type event manifested by disseminated urticaria, laryngeal
edema, and/or bronchospasm (or for example: food, insect bites, etc.) Patients with drug
allergies, manifest solely by rash, and/or urticaria are not excluded.
No history of angioedema or recurrent urticaria (an isolated episode of urticaria is not a

fever greater than or equal to 38.2 degrees Celsius.
No known allergy to E. coli-derived products.
No concurrent use of beta adrenergic blocking agents.
No concurrent use of other investigative agents.
No pregnancy or breast-feeding. Men and women of child-bearing potential, admitted to the
trial are to be advised to take adequate measures to prevent conception.
Patients maintained on interferon, chemotherapy or hematopoietic growth factors must have
these treatments discontinued for at least four weeks prior to entry into this study.
