Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older with lymphoma or multiple myeloma who are scheduled for an autologous stem cell transplant.

Probably not a fit

Patients with hypersensitivity to antihistamines or those who have recently used G-CSF may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study investigates whether loratadine is more effective than a placebo in preventing bone pain associated with G-CSF during autologous hematopoietic stem cell transplants in patients with lymphoma or multiple myeloma. The trial will involve adult participants who meet specific eligibility criteria, including a documented diagnosis of lymphoma or multiple myeloma and the need for a stem cell transplant. Participants will be randomly assigned to receive either loratadine or a placebo, and the severity of bone pain will be monitored throughout the treatment period.

Why it matters

Potential benefit: If successful, this study could provide a new method to alleviate bone pain for patients undergoing stem cell transplants.

How similar studies have gone: While similar studies have explored pain management in stem cell transplant patients, the specific use of loratadine for G-CSF-related bone pain is a novel approach.
