Background• The development of G-CSF,
particularly pegfilgrastim, has enabled oncologists to maintain dose intensity and to utilize “dose-dense” chemotherapy ( by limiting the severity and duration of neutropenia)
• This may lead to an improvement in patient survival
• The toxicity of pegfilgrastim is minimal and usually limited to bone pain
![Page 4: Prevention of Pegfilgrastim-induced Bone Pain (PIP): A URCC CCOP Randomized, Double-blind, Placebo-controlled Trial of 510 Cancer Patients Jeffrey J. Kirshner,](https://reader036.fdocuments.us/reader036/viewer/2022062719/56649ec05503460f94bcae0e/html5/thumbnails/4.jpg)
Background
• The incidence of pegfilgrastim-induced bone pain ranges from 26-59 % and can be “severe” in up to 24 % of patients
• Discontinuation of pegfilgrastim could lead to less effective chemotherapy dosing and a decrease in patient survival
![Page 5: Prevention of Pegfilgrastim-induced Bone Pain (PIP): A URCC CCOP Randomized, Double-blind, Placebo-controlled Trial of 510 Cancer Patients Jeffrey J. Kirshner,](https://reader036.fdocuments.us/reader036/viewer/2022062719/56649ec05503460f94bcae0e/html5/thumbnails/5.jpg)
Community Based Survey of 100 Patients (Kirshner, et al: Community Oncology 2007)
• 59% incidence of pegfilgrastim-induced pain• 24% incidence of severe pain (>5/10)• NSAIDs seemed to be the most effective
analgesic for relief of pain, particularly naproxen
![Page 6: Prevention of Pegfilgrastim-induced Bone Pain (PIP): A URCC CCOP Randomized, Double-blind, Placebo-controlled Trial of 510 Cancer Patients Jeffrey J. Kirshner,](https://reader036.fdocuments.us/reader036/viewer/2022062719/56649ec05503460f94bcae0e/html5/thumbnails/6.jpg)
“An Ounce of Prevention Is Worth a Pound of Cure”• It is better to prevent pain than to treat it
once it occurs• This could improve QOL and possibly
keep more patients on their chemotherapy schedule
• NSAIDs seem to be somewhat effective in relieving pegfilgrastim-induced pain
• NSAIDs have few side-effects and are relatively inexpensive
![Page 7: Prevention of Pegfilgrastim-induced Bone Pain (PIP): A URCC CCOP Randomized, Double-blind, Placebo-controlled Trial of 510 Cancer Patients Jeffrey J. Kirshner,](https://reader036.fdocuments.us/reader036/viewer/2022062719/56649ec05503460f94bcae0e/html5/thumbnails/7.jpg)
Study Objectives• To determine if naproxen can reduce the
incidence, severity and duration of pegfilgrastim-induced pain
• To better assess the true incidence of this pain in a large cross-section of patients treated by community oncologists
• To determine if there are risk factors which predict the development of such pain
• To determine if there are factors which predict efficacy of naproxen

Study Drug
• Naproxen 500 mg or matching placebo was begun at BID dosing on the morning of pegfilgrastim administration
• Drug was continued for a minimum of 5 days and up to 8 days if pain continued
![Page 10: Prevention of Pegfilgrastim-induced Bone Pain (PIP): A URCC CCOP Randomized, Double-blind, Placebo-controlled Trial of 510 Cancer Patients Jeffrey J. Kirshner,](https://reader036.fdocuments.us/reader036/viewer/2022062719/56649ec05503460f94bcae0e/html5/thumbnails/10.jpg)
Questionnaires• Patient rated their pain on a daily
basis, using a scale of 0-10 (Brief Pain Inventory)
• Quality of Life (QOL) assessments before and after treatment, utilizing “Symptom Inventory”
• Any additional medications to control pain were documented (additional NSAIDs were excluded)
![Page 11: Prevention of Pegfilgrastim-induced Bone Pain (PIP): A URCC CCOP Randomized, Double-blind, Placebo-controlled Trial of 510 Cancer Patients Jeffrey J. Kirshner,](https://reader036.fdocuments.us/reader036/viewer/2022062719/56649ec05503460f94bcae0e/html5/thumbnails/11.jpg)
Statistical Measures
• Primary outcome was measurement of the AUC from baseline to Day 5 (Day 1= Day of pegfilgrastim administration)
• Incidence of any pain and severe pain (>5/10) was measured as well as duration of pain

Duration of Pain
• 2.40 days (placebo) vs. 1.92 days (naproxen)
• P= 0.005
![Page 24: Prevention of Pegfilgrastim-induced Bone Pain (PIP): A URCC CCOP Randomized, Double-blind, Placebo-controlled Trial of 510 Cancer Patients Jeffrey J. Kirshner,](https://reader036.fdocuments.us/reader036/viewer/2022062719/56649ec05503460f94bcae0e/html5/thumbnails/24.jpg)
Risk Factors for Pain
• No relationship to age, types of cancer nor chemotherapy
• Suggestion that pegfilgrastim induced pain may be more frequent in African-Americans (but only 33 patients): AUC 12.88 vs 6.48
![Page 25: Prevention of Pegfilgrastim-induced Bone Pain (PIP): A URCC CCOP Randomized, Double-blind, Placebo-controlled Trial of 510 Cancer Patients Jeffrey J. Kirshner,](https://reader036.fdocuments.us/reader036/viewer/2022062719/56649ec05503460f94bcae0e/html5/thumbnails/25.jpg)
Relationship to Efficacy of Naproxen• No effect of age, race, type of cancer
nor chemotherapy regimen
![Page 26: Prevention of Pegfilgrastim-induced Bone Pain (PIP): A URCC CCOP Randomized, Double-blind, Placebo-controlled Trial of 510 Cancer Patients Jeffrey J. Kirshner,](https://reader036.fdocuments.us/reader036/viewer/2022062719/56649ec05503460f94bcae0e/html5/thumbnails/26.jpg)
Adverse Events
• None reported on either study arm• Specifically, no reports of
gastrointestinal bleeding or GI distress
![Page 27: Prevention of Pegfilgrastim-induced Bone Pain (PIP): A URCC CCOP Randomized, Double-blind, Placebo-controlled Trial of 510 Cancer Patients Jeffrey J. Kirshner,](https://reader036.fdocuments.us/reader036/viewer/2022062719/56649ec05503460f94bcae0e/html5/thumbnails/27.jpg)
Conclusions• Naproxen 500 mg BID is effective in
reducing the incidence, severity and duration of pegfilgrastim induced bone pain
• It should be considered for patients beginning pegfilgrastim, providing there are no contraindications
• A significant percentage of patients still will experience pegfilgrastim induced pain and there is a need to develop more effective preventive treatments
