Detailed Description
The study aims to include 20 patients with multiple myeloma that are initiating bortezomib treatment. The patients must follow their normal treatment cycles while getting blood drawn during their treatment period however maximal 9 cycles.
Blood is dawn before treatment initiation and approximately once per cycle in order to measure neurofilament light chain (NFL) before and during treatment. The primary outcome is to relate the level of NFL during treatment with the level at baseline and as a secondary outcome to relate the level of NFL to the cumulative dose of bortezomib.

Outcome Measures
Primary Outcome Measures
- Level of plasma neurofilament light chain [Baseline (before treatment initiation)]
Plasma neurofilament light chain before treatment with bortezomib. (Cycle length can vary).
- Level of plasma neurofilament light chain [Between day 8 and 15 in cycle 1 (each cycle is often between 3-6 weeks)]
Plasma neurofilament light chain during treatment with bortezomib.
- Level of plasma neurofilament light chain [Day 1 in cycle 2 (each cycle is often between 3-6 weeks)]
Plasma neurofilament light chain during treatment with bortezomib. (Cycle length can vary).
- Level of plasma neurofilament light chain [Day 1 in cycle 3 (each cycle is often between 3-6 weeks)]
Plasma neurofilament light chain during treatment with bortezomib. (Cycle length can vary).
- Level of plasma neurofilament light chain [Day 1 in cycle 4 (each cycle is often between 3-6 weeks)]
Plasma neurofilament light chain during treatment with bortezomib. (Cycle length can vary).
- Level of plasma neurofilament light chain [Day 1 in cycle 5 (each cycle is often between 3-6 weeks)]
Plasma neurofilament light chain during treatment with bortezomib. (Cycle length can vary).
- Level of plasma neurofilament light chain [Day 1 in cycle 6 (each cycle is often between 3-6 weeks)]
Plasma neurofilament light chain during treatment with bortezomib. (Cycle length can vary).
- Level of plasma neurofilament light chain [Day 1 in cycle 7 (each cycle is often between 3-6 weeks)]
Plasma neurofilament light chain during treatment with bortezomib. (Cycle length can vary).
- Level of plasma neurofilament light chain [Day 1 in cycle 8 (each cycle is often between 3-6 weeks)]
Plasma neurofilament light chain during treatment with bortezomib. (Cycle length can vary).
- Level of plasma neurofilament light chain [Day 1 in cycle 9 (each cycle is often between 3-6 weeks)]
Plasma neurofilament light chain during treatment with bortezomib. (Cycle length can vary).
Secondary Outcome Measures
- Level of plasma neurofilament relative to cumulative dose of bortezomib [From cycle 1 (each cycle is often between 3-6 weeks) and forward, maximum 9 cycles in total. An average of 1 year.]
Plasma neurofilament light chain relative to the cumulative dose of bortezomib in patients.
- Degree of peripheral neuropathy [From cycle 1 (each cycle is often between 3-6 weeks) and forward, maximum 9 cycles in total. An average of 1 year.]
Using questionnaire Chemotherapy-induced peripheral neuropathy 20 (CIPN20), grading
- Degree of peripheral neuropathy [From cycle 1 (each cycle is often between 3-6 weeks) and forward, maximum 9 cycles in total. An average of 1 year.]
Using Common Terminology Criteria for Adverse Events (CTCAE) version 5, grading 1-5 with 1 being the mildest case and 5 being the worst.
