About
The primary objective of the study is to estimate the difference in bone pain between breast cancer patients receiving chemotherapy and pegfilgrastim and either no prophylactic intervention, prophylactic naproxen, or prophylactic loratadine.
Full description
In this study, the investigational products are naproxen, a non-steroidal antiinflammatory drug (NSAID), and loratadine, an anti-histamine. Both agents are being investigated as prophylactic medications to reduce the incidence and/or severity of bone pain in breast cancer patients receiving adjuvant or neoadjuvant myelosuppressive chemotherapy and pegfilgrastim prophylaxis.
Pegfilgrastim treatment is used to stimulate bone marrow to produce more neutrophils to help fight infections in patients undergoing chemotherapy.

Exclusion Criteria
History of other malignancy within the past 5 years, with the following exceptions:
Planning to receive weekly chemotherapy
Ongoing chronic pain, or other painful conditions requiring treatment (including immediate post-operative treatment of surgical or procedural-associated pain) as determined by the investigator
Chronic oral steroid use. Premedication related to the administration of chemotherapy, and use of anti-emetics is allowed, per usual clinical practice
Chronic use of oral non-steroidal anti-inflammatory drug (NSAIDs) or oral antihistamines outside of those dictated by the randomization groups outlined in the protocol, with the following exception:
Prior chemotherapy treatment for cancer within 5 years of current breast cancer diagnosis
Prior use of granulocyte colony stimulating factor (G-CSF)
History of clinically significant gastrointestinal (GI) bleeding, history of GI ulcers or active GI bleeding within 6 months prior to randomization
History of clinically significant bleeding disorders, thromboembolism within 6 months prior to randomization
Currently enrolled in, or less than 30 days since ending, another clinical trial which includes language directing G-CSF (filgrastim, pegfilgrastim, other) or granulocyte-macrophage colony-stimulating factor (GM-CSF) (sargramostim) use
Currently enrolled in, or less than 30 days since ending, another interventional clinical trial which includes a blinded treatment or blinded treatment arm (whether or not the subject is randomized to the blinded arm)
Currently enrolled in, or less than 30 days since ending, another interventional clinical trial which includes the use of any agent not currently considered to be standard therapy for the adjuvant or neoadjuvant treatment of stage I-III breast cancer based on National Comprehensive Cancer Network (NCCN) Clinical Practice Guidelines in Oncology for Breast Cancer
Currently enrolled in, or less than 30 days since ending, any pain intervention study
Female subjects who are pregnant or lactating or of reproductive potential not willing to employ an effective method of birth control during treatment and for 17 days after discontinuing study treatment
History or evidence of any other clinically significant disorder, condition or disease (with the exception of those outlined above) that, in the opinion of the Investigator or Amgen, if consulted, would pose a risk to subject safety or interfere with the study evaluation, procedures or completion
