Randomized, Placebo Controlled Study of Loratadine for Pegfilgrastim Induced Bone Pain in Patients With Aggressive Lymphoma
Randomized, Placebo Controlled Study of Loratadine for Pegfilgrastim Induced Bone Pain in Patients With Aggressive Lymphoma
The goal of this clinical research study is to learn if loratadine can control bone pain caused by pegfilgrastim (a drug given after chemotherapy to help raise white blood cell counts).
Study Groups:
If you are found to be eligible to take part in this study, you will be randomly assigned (as in the flip of a coin) to 1 of 2 groups. You will have an equal chance of being in either group.
A placebo is not a drug. It looks like the study drug but is not designed to treat any disease or illness. It is designed to be compared with a study drug to learn if the study drug has any real effect.
Both groups will receive pegfilgrastim after standard of care chemotherapy.
Neither you nor the study staff will know when you are receiving the study drug or the placebo. However, if needed for your safety, the study staff will be able to find out what you are receiving.
Study Drug Administration:
Each study cycle is 21 days.
On Day 1 of Cycles 1-6, you will receive pegfilgrastim through a needle under the skin.
On Days 1-7 of Cycles 1-4, you will take loratadine/placebo by mouth 1 time every day.
If you have any bone pain during Cycles 1-4, you will take loratadine on Days 1-7 of Cycles 5 and 6. If you do not have bone pain, you will be off study after Cycle 4.
The study doctor will decide if you need any extra pain medication.
You will be given a diary to write down when you take loratadine/placebo, and to write down the amount and time of any pain medications they need, and to describe the location, severity, and description of the pain you experience.
Study Visits:
During Cycles 1-4 (and if you have pain, during Cycles 6-7), before you receive pegfilgrastim and on Day 7, you will complete 3 questionnaires about your bone pain and how you are feeling. The should take about 20 minutes to complete. If you are not coming into the clinic, you will be asked to mail in the questionnaires and your diary.
Before each cycle starts, blood (about 2-4 teaspoons) will be drawn for routine tests and to test your liver, bone, and kidneys.
On Day 1 of Cycles 2-6, you will have a physical exam, and blood (about 3-4 teaspoons) will be drawn for routine tests.
On Days 7 and 14 of each cycle (+/- 3 days), blood (about 2-4 teaspoons) will be drawn for routine tests.
Length of Study:
You may continue taking the study drugs for up to 18 weeks (6 cycles). You will no longer be able to take the study drug if the disease gets worse, if intolerable side effects occur, or if you are unable to follow study directions.
Your participation in this study will be over after the end-of-study visit.
End-of-Study Visit:
Within 8 weeks after your last dose of study drugs:
This is an investigational study. Loratadine is FDA approved and commercially available for the treatment of seasonal allergies. Pegfilgrastim is FDA approved and commercially available for improvement of chemotherapy-related neutropenia. The use of loratadine to control bone pain is investigational.
Up to 56 participants will be enrolled in this study. All will take part at MD Anderson.
