Phase 2a Study Evaluating the Arsenic Trioxide (ATO) in Systemic Lupus (SLE) (Protocol LUPSENIC)

Phase 2
Terminated
Conditions
Systemic Lupus
Interventions
Registration Number
NCT01738360
Lead Sponsor
Nantes University Hospital
Brief Summary

Primary objectives :

* To investigate the safety and the tolerability of ATO by IV infusions to patients with SLE,

* To determine the maximum tolerated dose of ATO.

Secondary objectives :

* Evaluation of the clinical and biological response of the SLE to ATO,

* Time of relapse in case of positive response,

* Determination of the efficacy,

* Pharmacokinetic study of ATO.

GroupInterventionDescription
Arsenic trioxideArsenic trioxideThirteen patients will be successively included in this study at 6 different dose levels of arsenic trioxide (0.075, 0.10, 015, 0.20, 0.25 and 0.30 mg / kg / day).
Primary Outcome Measures
NameTimeMethod
Cardiac adverse events whatever grade and any adverse event of grade 3 or 430 days after the last infusion

The definition of toxicity will be based on "Common Terminology Criteria for Adverse Events, version 4" of the U.S. Department of Health and Human Services, National Institutes of Health / National Cancer Institute.

The investigators will consider the occurrence of a significant toxicity if at least one of the following events is observed :

* Any symptomatic toxicity (and / or abnormality) cardiac and / or QTc prolongation \> 480 msec.,

* Apart from cardiac toxicity, toxicity of any grade 3 or 4 and irreversible toxicity (within 30 days) of any grade 1 or 2.

Secondary Outcome Measures
NameTimeMethod
Composite response of SLE30 months

Combined clinical response using the composite response of SLE or SRI (SLE Responder Index) (SLEDAI + BILAG (British Isles Lupus Assessment Group) + PGA) : a positive response is defined by a reduction of SELENA SLEDAI of at least 4 points, no worsening ( \> 0,3 point) of the physician's global assessment (PGA), no new score "A" and no more than one new score "B" about BILAG. This composite index is now the benchmark tool for evaluating therapeutic protocols in SLE.
