NCT03499808 · STUDY IN CONTEXT
S1702 Isatuximab in Treating Patients With Relapsed or Refractory Primary Amyloidosis
Draft scope assessment: narrower. Linked by condition-string match at the cancer-entity level. The study's eligibility - stage, biomarker, treatment line and prior therapy - has not been reconciled against this page's definition, so its population is narrower than this page in ways not yet recorded. The condition was transformed or resolved through the terminology hierarchy to reach this cancer type, so the link itself is a candidate a reviewer must confirm. Found by searching ClinicalTrials.gov for this cancer type, restricted to studies that have posted results to the registry. No FDA notice, FDA label or NCI summary held by this site cites this study. Because the search asked for posted results, studies without posted results were never looked for, so their absence from this page means nothing.

Linked outcomes
To assess the efficacy as measured by the confirmed overall hematologic response rate (partial response, very good partial response, complete response) of isatuximab in relapsed/ refractory systemic light chain (AL) amyloidosis. Measured as rate of partial response or better. Partial response is defined as a dFLC decrease of ≥ 50%, but remaining \> 4.0 mg/dL. Very good partial response is defined as the difference between involved and uninvolved FLCs \[dFLC\] \< 4.0 mg/dL. Complete response is defined as laboratory values within the normal range free light chain (FLC) ratio (0.25 - 1.65) and negative serum and urine immunofixation.
Only adverse events that are possibly, probably or definitely related to study drug are reported.
Overall survival is measured from date of registration to date of death due to any cause. Patients last known to be alive are censored at date of last contact. While OS was assessed up to 4 years, 4 year estimates were not reached. We are reporting the 24 month estimate (how many participants reached survival time of at least 24 months).
Duration of response is measure as time between hematologic response and hematologic progression. Hematologic progression is defined as 50% increase from nadir. While duration of response was assessed up to 4 years, 4 year estimates were not reached. We are reporting the 24 month estimate (how many participants achieved 24 month duration of response)
To evaluate time to hematologic response. Partial response is defined as a dFLC decrease of ≥ 50%, but remaining \> 4.0 mg/dL. Very good partial response is defined as the difference between involved and uninvolved FLCs \[dFLC\] \< 4.0 mg/dL. Complete response is defined as laboratory values within the normal range free light chain (FLC) ratio (0.25 - 1.65) and negative serum and urine immunofixation.
To evaluate progression-free survival (24 month estimate) Hematologic progression is defined as 50% increase from nadir, or from baseline (if there was no response) in any ONE OR MORE of the following: 1. Serum M-protein: 50% increase in Serum M protein to a value greater than 0.5 g/dL. 2. Urine M protein: 50% increase in Urine M protein to a value greater than 200 mg/day (a visible peak must be present) 3. Free light chain increase of 50% to a value greater than 10 mg/dL
