Loratadine for Improvement of Bone Pain in Patients With Chronic Granulocyte-Colony Stimulating Factor (G-CSF) Use

Phase 2
Terminated
Conditions
Bone Pain
Interventions
Drug: Loratadine
Drug: Placebo
Registration Number
NCT03883386
Lead Sponsor
University of Michigan
Brief Summary

G-CSF causes a release of histamine that may be a cause of chronic bone pain. Loratadine targets histamine, and so may be effective in reducing bone pain.The researchers plan to prospectively assess the effectiveness of loratadine for chronic bone pain in patients with chronic G-CSF use.

Primary Outcome Measures
NameTimeMethod
Change in Pain Severity Scores as Measured by the Brief Pain Inventory (BPI)Week 1 (baseline week), week 2 (placebo or loratadine), and week 4 (placebo or loratadine).

The Brief Pain Inventory (BPI) rapidly assesses the severity of pain and its impact on functioning. The questions ask participants to rate their pain in the prior 24-hours OR prior 7-day on a 0 to 10 Numerical Rating Scale (NRS), where "0" indicates "No pain" and "10" indicates "Pain as bad as you can imagine."

Modified BPI: Included the pain intensity subscale, it is a Numerical Rating Scale with 4 questions (3-6): each item is ranked where 0 is no pain - 10 the worst pain.

The Modified BPI will be measured on Days 2, 4, and 6. The full BPI will be measured on Day 7. On day 7 only responses from questions 3-6 will be analyzed for this outcome and a mean composite score for Days 2, 4, 6, and 7 will be calculated.

Secondary Outcome Measures
NameTimeMethod
Change in Pain Interference in Patients as Measured by the Brief Pain Inventory (BPI)Week 1 (baseline week), week 2 (placebo or loratadine), and week 4 (placebo or loratadine).

Brief Pain Inventory (BPI) asks the participant to rate how their pain interferes with daily activities where "0" indicates "does not interfere and "10" indicates "completely interferes". The Pain Intensity Scale scores (Numerical Rating Scale (NRS)) for 7 questions: general activity, mood, walking ability, normal work, relations with other people, sleep, enjoyment of life from (BPI question 9A-G); 0 no life interference - 10 complete interference. Pain interference will be assessed on day 7 of each week.
