Effects of genetics on methotrexate clearance in lymphoma patients

Pharmacogenomics Effects on High-Dose Methotrexate Clearance in Patients With Diffuse Large B-Cell Lymphoma

Observational Ohio State University Comprehensive Cancer Center · NCT06031194

This study is trying to see how genetic differences affect how well lymphoma patients clear high doses of methotrexate and if these differences lead to more side effects.

What this trial studies

This observational study evaluates how genetic variations affect the clearance of high-dose methotrexate in patients diagnosed with diffuse large B-cell lymphoma or primary central nervous system lymphoma. The primary objectives include identifying single nucleotide polymorphisms (SNPs) associated with delayed methotrexate clearance and exploring any links between these SNPs and increased toxicity. Participants will provide blood samples and have their medical records reviewed to gather relevant data. The study aims to enhance understanding of pharmacogenomics in cancer treatment.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older diagnosed with diffuse large B-cell lymphoma or primary central nervous system lymphoma who are scheduled to receive high-dose methotrexate.

Not a fit: Patients with currently active second malignancies or those who are pregnant or breastfeeding may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to personalized treatment approaches that optimize methotrexate dosing and reduce toxicity for lymphoma patients.

How similar studies have performed: Other studies have shown promise in pharmacogenomic approaches to cancer treatment, suggesting potential for success in this area.
