Risky extrapolation to dc of data
WebA method is introduced to assess the "statistical risk" associated with the extrapolation of the initial clinical (phase I) dose from experimental animal data. The best clinical prediction is obtained when one uses the experimental MTD expressed in mg/kg for the more sensitive of the large animal species (dogs or monkeys). Webthe basis of additional available data, e.g. from studies of a lower reliability rating or from non-testing methods, if these show a distinct tendency in support of a certain result. R.10.2.2.1 Use of data from laboratory toxicity tests . The data used for derivation of the PNECs are usually results from single species laboratory toxicity tests.
