April 8, 2026 updated by: Intergroupe Francophone du Myelome

Diagnostic Performance of Spot Urine Sample for the Monoclonal Components Detection in Patients With Multiple Myeloma RHU(M)M Random or H24 Urine in (Multiple) Myeloma

The primary objective of the study is to evaluate at Day 1 Cycle 2, the detection sensitivity of the urinary monoclonal component on a spot urine sample, compared to the reference measurement on 24-hour urine, in patients with Multiple Myeloma.

Study Overview

Status

Active, not recruiting

Conditions

Detailed Description

To evaluate the detection sensitivity of the urinary monoclonal component on a spot urine sample, compared to the reference measurement on 24-hour urine, in Multiple Myeloma patients.

180 evaluable patients are required. For each of them, both spot urine sample and 24h urine sample will be collected at Cycle1 Day1, Cycle 2 Day 1 and Cycle 4 Day 1.

The detection of urine monoclonal component will be performed by urine protein electrophoresis (quantitative) and urine immunofixation (qualitative).

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Evaluate the detection sensitivity of the urine monoclonal component on spot urine sample
Time Frame: at the first Day of Cycle n°2 (each cycle is 28 days or 21 days)

Evaluate the detection sensitivity of the urine monoclonal component on spot urine sample compared to the reference measurement of 24 hours urine.

Sensitivity is defined as the proportion, among the patients with positive urinalysis results on 24 hours urine, of positive results on spot urine sample. Evaluation is performed by urine protein electrophoresis and urine immunofixation

at the first Day of Cycle n°2 (each cycle is 28 days or 21 days)

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Evaluate the specificity of urine monoclonal component detection on spot urine sample
Time Frame: at the first Day of cycle n°2 (each cycle is 28 days or 21 days)

Evaluate the specificity of urine monoclonal component detection on sample at C2D1 compared to the reference measurement of 24 hours urine sample.

Specificity is defined as the proportion, among patients with negative urinalysis results on 24 hours urine, of negative results on the spot urine sample.

at the first Day of cycle n°2 (each cycle is 28 days or 21 days)
Evaluate the sensitivity and specificity of urine monoclonal component detection on spot urine sample
Time Frame: at the first day of cycle n°1 and cycle n°4 (each cycle is 28 days or 21 days)
Evaluate the sensitivity and specificity of urine monoclonal component detection on spot urine sample at C1D1 and C4D1 compared to reference measurement of 24hours urine sample
at the first day of cycle n°1 and cycle n°4 (each cycle is 28 days or 21 days)
Compare the responses rate
Time Frame: at the first day of cycle n° 2 and cycle 4 (each cycle is 28 days or 21 days)
Compare the rate of partial responses, very good partial responses and complete responses (IMWG criteria) but only on the urinary monoclonal component) at C2D1 and C4D1 between the two types of samples (spot urine sample and 24hours urine sample)
at the first day of cycle n° 2 and cycle 4 (each cycle is 28 days or 21 days)
Compare the monoclonal component / creatininuria ratios
Time Frame: at the first day of cycle n° 1,2 and 4
Compare the monoclonal component / creatininuria ratios in both samples (spot urine sample and 24hours urine sample) for components monoclonal which are quantifiable in both types of urine samples
at the first day of cycle n° 1,2 and 4
Define the equivalent of 200 mg / 24H (current consensus threshold of measurable urinary disease)
Time Frame: at the first day of cycle n° 1 (each cycle is 28 days or 21 days)
Define the equivalent of 200 mg / 24H (current consensus threshold of measurable urinary disease) at C1D1 and on the others points, if the monoclonal component is quantifiable)
at the first day of cycle n° 1 (each cycle is 28 days or 21 days)
Assess the association between the rate of serum light chains and concentration of monoclonal components
Time Frame: at first day of cycle 2 (each cycle is 28 days or 21 days)
To assess the association between serum light chains and concentration of monoclonal components for both types of urine samples.

Time Frame: at first day of cycle 2 (each cycle is 28 days or 21 days)
To Evaluate if the rate of urine monoclonal component (in g/L)could by calculated by the difference between proteinuria (in g/L) and albuminuria (in g/L)
