Fenofibrate Role in the Prophylaxis From Peripheral Neuropathy Induced by Bortezomib, Lenalidomide and Dexamethasone (VRd) Protocol in the Treatment of Patients With Multiple Myeloma (MM)

This study aims at evaluating the possible beneficial role of Fenofibrate in attenuating the peripheral neuropathy associated with bortezomib (velcade), lenalidomide (revlimid), and dexamethasone (VRd) regimen in newly diagnosed multiple myeloma patients.The study aims to asses VRd protocol induced peripheral neuropathy through: 1. The implication of National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE, Version 5, 2017) and The use of Neurotoxicity-12 items questionnaire score (Ntx-12) from the validated Functional Assessment of Cancer Therapy/Gynecologic Oncology Group "FACT/GOG-Ntx-12 for grading of neuropathy at baseline and by the end of every two VRd cycles. 2. The assessment of biological markers: Brain -derived neurotrophic factor (BDNF) and Neuro-filament light chain (NfL). through comparing two groups: Group one: (Control group; n=22): which will receive 6 cycles of VRd regimen (each cycle will be given every 28 days). Group two: (Fenofibrate group; n=22): which will receive the same regimen plus Fenofibrate 160 mg once daily.

Inclusion Criteria:

* Age ≥ 18 years old.
* Newly diagnosed MM patients according to the revised International Myeloma Working Group Diagnostic Criteria for the diagnosis of Multiple Myeloma (IMWG).
* Patients being treated by bortezomib-based VRd chemotherapy regimen.
* Patients with performance status \<2 according to Eastern Cooperative Oncology Group (ECOG) score.

Exclusion Criteria:

* Patients with prior exposure to neurotoxic agents (Cis-platin, vincristine, taxanes, foscarnet, INH, etc..) in the last 6 months.
* Concomitant use of antioxidant vitamins (vitamin A, C, E), anticonvulsants, tricyclic antidepressants, other medications used for neuropathic pain (gabapentin, lamotrigine, carbamazepine).
* Preexisting peripheral neuropathy resulting from other causes such as diabetes and brain disorders, hypothyroidism, autoimmune diseases, hepatitis C.
* Patients with inflammatory diseases (ulcerative colitis, rheumatoid arthritis).
