Brief Summary

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.

Detailed Description

Multiple myeloma is considered an incurable disease so several regimens are available for the management of multiple myeloma.

Among these regimens there is the bortezomib, lenalidomide and dexamethasone (RVd or VRd) regimen which is the preferred induction regimen for most patients with newly diagnosed multiple myeloma (NDMM).

Bortezomib has hematologic and non-hematologic adverse reactions. From the non-hematologic adverse reactions there is the bortezomib-induced peripheral neuropathy (BIPN) that remains the most intractable common adverse reactions that occur during bortezomib treatment with no recommended therapies available for preventing or treating existing BIPN.

Fenofibrate a peroxisome proliferator-activated receptor-alpha (PPARα) agonist that is widely used in the management of hypercholesterolemia and hypertriglyceridemia has been proposed as a key lipid metabolism modulator and regulator of inflammation.

Preclinical studies showed that treatment with fenofibrate partially reversed and prevented the development of mechanical and cold hypersensitivity induced by paclitaxel through the regulation of peroxisome proliferator-activated receptor-alpha (PPAR-α) expression and decrease neuroinflammation in the dorsal root ganglia (DRG) without decreasing the antitumoral effect of paclitaxel.

Arm && Interventions

Group	Intervention	Description
Fenofibrate group	Bortezomib + Lenalidomide + Dexamethasone + Fenofibrate 160 mg tablet	22 participants will receive 6 cycles of (VRd) regimen plus Fenofibrate 160 mg tablet once daily during the period of the 6 cycles.
Control group	Bortezomib + Lenalidomide + Dexamethasone	22 participants will receive 6 cycles of VRd regimen (each cycle will be given for 28 days)

Primary Outcome Measures

Name	Time	Method
The change in percentage of patients with peripheral neuropathy grade ≥ 2 with the variation of both 12-item neurotoxicity questionnaire (Ntx-12) total score and NCI-CTCAE, v5.	The use of NCI-CTCAE, Version 5, 2017 and "FACT/GOG-Ntx-12" for the grading of peripheral neuropathy will be done at the baseline and by the end of every two VRd cycles ( the duration of each cycle is 28 days) during the 6 VRd cycles duration.	The change in percentage of patients with peripheral neuropathy grade ≥ 2 using the National Cancer Institute Common Terminology Criteria for Adverse Events, version 5 (NCI-CTCAE, v5) ( where the higher the score the more severity of the peripheral neuropathy) and the use of the Functional Assessment of Cancer Therapy/Gynecologic Oncology Group - Neurotoxicity 12 Item Version (FACT/GOG-NTX-12) to assess (where the higher the score, the better the Quality of life).

Secondary Outcome Measures

Name	Time	Method
The change in serum levels of the measured biological markers Brain -derived neurotrophic factor (BDNF) and Neuro-filament light chain (NfL).	The assessment of serum level of the biological markers Brain -derived neurotrophic factor (ng/ml) and Neuro-filament light chain (pg/ml) will be done at the baseline and within 1 week after the 6th VRd cycle ( the duration of each cycle is 28 days).	The assessment of serum level of the biological markers: Brain -derived neurotrophic factor (BDNF) (in ng/ml) and Neuro-filament light chain (NfL)( in pg/ml) will be done at the baseline (before the initiation of the treatment protocol) and within 1 week after the last VRd cycle (the 6th cycle) ( the duration of each cycle is 28 days).
