What this trial studies

This early phase I trial investigates the effectiveness of loratadine, an antihistamine, in alleviating bone pain caused by granulocyte-colony stimulating factor (G-CSF) in patients with multiple myeloma undergoing stem cell mobilization. Participants are randomly assigned to receive either loratadine or a placebo starting five days before G-CSF treatment and continuing until five days after stem cell collection. The study aims to evaluate the efficacy of loratadine and assess the need for additional pain relief medications. Additionally, it seeks to identify risk factors for developing G-CSF induced bone pain.

Who should consider this trial

Good fit: Ideal candidates include patients with a confirmed diagnosis of multiple myeloma who are able to take oral medications.

Not a fit: Patients who are non-English speaking or have known allergies to the study medications may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new method for managing bone pain in multiple myeloma patients during stem cell mobilization.

How similar studies have performed: While this approach is novel in the context of G-CSF induced bone pain, similar studies using antihistamines for pain management have shown promise.
