5. Summary of Data Reported and Evaluation

5.1 Exposure data

Prednimustine has been used as a cytostatic drug, mainly for the treatment of malignancies of lymphatic tissue.

5.3 Human carcinogenicity data

No data were available to the Working Group.

5.4 Other relevant data

In humans, prednimustine causes leukopenia and thrombocytopenia; in experimental animals, it causes lymphopenia. It is hydrolysed to chlorambucil and prednisolone in vivo.
