    Many endpoints in toxicity testing can be adressed by a combination of approaches such as TTC, read-across powered by sophisticated computational chemistry, targeted in vitro testing, and refined exposure assessments. Thus, there is a much reduced need for testing if more science is introduced. Some of the reduced testing may increase uncertainty.

    Unlike pharmaceuticals agro-chemicals,general chemicals and other substaces rely almost totally on experimental toxicology to determine the potential hazard and risk to those occupationally exposed or others through adventitious exposure. At present there is no substitute for the use of integrated organ systems provided by whole animal experiments. If anything there has been a progressive loss in the quality of animal experimentation due to the desire to substitute in vivo studies with in vitro experiments that do nowhere to substitute for relevant in vivo studies. The political rather than science based movement to more in vitro testing has resulted in faster, cheaper and less meaningful results.
    If you mandate for poor science you will certainly be successful.

    While I might agree on limiting research using primates or domestic animals or wildlife in general, in general, research on experimental animals is still indispensable in toxicology, pharmacology and oncology. Contrary to public belief, in most instances, this type of research involves selected breeds with well known genetic features, specifically developed for research purposes. There are strict guidelines on protecting animal welfare in the stabulary and during the experiments. Ethics approval for animal experiments is already in place. Introducing further restrictions would limit scientific progress and human wellbeing in perspective.

    While I certainly support the aim of reducing animal testing in the framework of 3R (reduce, refine, replace), I do not support a complete abolishment of animal testing as I do not believe that current in vitro or in silico methods are sufficiently advanced to replace complex biological systems. Of course there are good replacements for some specific types of testing like acute toxicity or irritation; longer-term studies, however, cannot be modelled by alternative systems (yet).

    While many non-animal test methods are being developed, it is too early to use them to replace animal testing. There is a limit it what non-animal tests can tell you and much of the complaint about animal testing is that it doesn't model the human well. However, taking a step back into non-animal tests will decrease how well the tests model humans even more. Animal testing is not nice, but it is necessary and can't be fully replaced yet. What should be done is to demand non-animal testing be incorporated into animal tests to see how well they do or more likely do not correlate with results before ever considering eliminating animal testing.

    It is becoming increasingly clear that the current non-animal tests do not provide sufficiently reliable information about human toxicity compared to alternative tests. And with roughly 70,000 chemicals in commerce and only a thousand or so with sufficient data that provide sufficient, reliable data to inform important regulatory (not screening level priority setting), such as for National Ambient Air Quality and Drinking Water Standards, and Pesticide regulation decisions, it would take far too long and be far too costly to thoroughly evaluate each with the traditional animal based testing strategy. Thus, there is a critical need for the more informative and efficient alternative testing approaches called for in the memo calling for the agency to move to alternative approaches by 2035

    While animal models are not humans, they provide an inherently systems-based perspective on how a chemical or drug functions in a biological context. Multiple pathways including repair, pharmacokinetic, and compensatory processes are fully functional to provide a view of biological risk that isolated pathway indicators, no matter how many one can put on a plate can show. Modeling those comptox indicators and adverse outcome pathways remain a primitive science no matter how sophisticated the visual models area. They need much more sophistication and validation to be of any reliable value - in my opinion. If a food additive or drug is excluded with these test methods, there is little lost except perhaps something that might perhaps have been of value - likely not earth shattering. On the other hand, something that gets through has the potential of untoward damage. I believe the comptox approaches can be very valuable used in conjunction with judicious animal testing perhaps one day replacing animal test approaches. I would say dosing regimes including timing, species selection, and assessments have been overly standardized impeding their full interpretive value. Let the science evolve without knee-jerk responses to uninformed sentiments.

    Alternatives to animal testing include sophisticated tests using human cells and tissues (also known as in vitro methods), advanced computer-modeling techniques (often referred to as in silico models), and studies with human volunteers. These and other non-animal methods are not hindered by species differences that make applying animal test results to humans difficult or impossible, and they usually take less time to complete.

    The in vitro tests developed to date do not adequately address toxicity assessment for several critical organ systems, especially from gestation through adolescence, or behavior and cognitive function at the whole animal level. There is no wholistic or integrated approach to this in vitro work: just short-term assessment of organs or cells at different steps of development or adulthood using laboratory-derived tissues or cells in culture media that do no adequately represent the whole animal.
