Title MON 102100: Local Lymph Node Assay (LLNA) in Mice

Date 25-OCT-19

2. a) Is an extension needed to translate the document?

No

3. Type of incident identified in the study

New health or environmental hazard

4. Describe the incident identified in the study (e.g. study demonstrates an increased risk to non-Hodgkin's Lymphoma after exposure to pesticide X)

Two LLNAs (local lymph node assays) in mice were conducted with separate manufacturing batches of tioxazafen, based on OECD Test Guideline 429. Five concentrations of the tioxazafen (1%, 3%, 6.25%, 12.5%, and 25%) in acetone/olive oil (4:1 v/v) (AOO) or in 1% Pluronic¿¿¿¿ L92 Surfactant w/w in distilled water (1% Pluronic¿¿¿¿ L92) were topically applied to groups of healthy mice (five mice/treatment group) for three consecutive days. As a SI (stimulation index) of greater than or equal to 3 was observed in the tioxazafen treated groups,tioxazafen was considered positive for dermal sensitization potential in both studies.
