General comments

We, the signatories of this document represent European organisations where the majority of members and decision-makers are autistic. Our members are potential end users of the products of biomedical research that targets autism, as well as potential participants in clinical trials.

We feel that the EMA guidelines published in February 2016 do not serve the interests of our members. As autistic adults with long-term experience in supporting and advocating for others on the autism spectrum, we object to the following general features of the guideline.


01. The use of the words ‘disease’ and ‘patient’. As autistic people, we can be mildly, moderately or severely disabled, or merely different with the positive features of autism balancing the challenges. Autism, as such, is not a disease we suffer from, and the use of terminology that suggests this perpetuates distorted perceptions of our lives, adding to the stigma and daily challenges that we face. Most of us are not anyone’s ‘patients’ because of our autism, and even temporarily participating in biomedical research does not make us patients.

02. We object to the EMA describing autism as if it were a single condition that varies in intensity only, from mild through moderate to severe, and suggesting that one or a few medicinal products could be developed that benefit all or most people on the autism spectrum, at dosages adjusted to each level of severity. In the light of current research, as well as in our experience as autism advocates, autism spectrum conditions vary greatly in their genetic and other biological background, as well as their combinations of cognitive characteristics and the challenges each autistic person experiences (e.g. Wen et al., 2016, doi: 10.1371/journal.pone.0153329 ; Tordjman et al., 2014, doi: 10.3389/fpsyt.2014.00053 ).
This variation is not restricted to a single dimension of ‘severity’ only, in the manner the EMA draft implies. On the biological level, it means different genetic and epigenetic mechanisms affecting a large number of converging pathways, differences in hormonal and neurotransmitter levels and regulation, differences in synaptic functioning, differences in brain anatomy, connectivity and synchronization. Researchers should be warned that adjusting medication for autistic individuals is likely to never be a matter of adjusting the dosage only, based on perceived intensity of external autistic characteristics. Instead, completely different medicinal products are likely to benefit qualitatively different subgroups within the autism spectrum, and some medications that help one subgroup may harm others that appear superficially similar.

03. The guideline suggests that the ‘core symptoms’ of ASD to be targeted through biomedical interventions are the external behavioural features currently used as the key criteria for making a clinical diagnosis (e.g. “social communication and interaction, and repetitive behaviour which include sensory integration dysfunctions”, according to the DSM-5). Further, the guideline suggests that “A clinical effect on core symptoms of ASD should be demonstrated before efficacy on other associated symptoms can be claimed. Generally the development of treatments targeting single symptoms in autism is not encouraged”.
The external behavioural features do not reflect a single, shared set of biological features and they are not likely to respond to a single medicinal product in a large proportion of the autism spectrum. The characteristics assumed to be ‘associated’ or ‘single’ symptoms may actually often reflect the core biological characteristics of a subgroup within the spectrum, and thus be the more realistic target for a biomedical intervention. Rather than focusing on the idea of medicinal products for the entire autism spectrum as a single entity, researchers should focus on medicinal products that improve the quality of life for well-defined subgroups of the spectrum, where the target for biochemical intervention is a known or assumed core biological feature.

04. As autistic adults and advocates, we are keenly aware that for many of us the assumed core characteristics of autism are not the greatest obstacles in our lives. Many of us do not wish to change the way we interact socially, communicate, develop intense interests, engage in mannerisms that express our emotional states, or perceive sensory stimuli (the latter three being reduced to ‘repetitive behaviours’ in official clinical criteria). Many of us believe that these characteristics are inextricably linked to positive features and strengths associated with autism.
Instead, many of us have ‘single symptoms’ that do limit our ability to work or live independently, and such individuals often wish that these single issues could be addressed without extensive change to our personalities or general cognitive abilities. We insist that researchers should not be discouraged from, but rather encouraged to develop products that might help subgroups of autistic people to minimize harmful ‘associated symptoms’ such as anxiety, depression, problems with directing or maintaining attention, fatigue, sleep disorders, inertia (specific difficulty with initiating action), epilepsy, disturbances of energy metabolism, intestinal symptoms, or disorders of the immune system. This is not an entirely novel idea, as some researchers are already focusing on treating autism associated symptoms that impair well-being and daily functioning (Frye and Rossignol, 2016, 10.4137/CMPed.S38337 )

05. Researchers should be encouraged to involve potential end users, particularly autistic adults who are capable of reflecting on the potential benefits of medicinal products and associated ethical questions, in every stage of the research process. There is evidence that current autism research in general does not reflect the needs and wishes of autistic people or their families (e.g. Gotham et al., 2015 doi: 10.1177/1362361315583818 ), and is often distanced from the everyday reality of the people it is supposed to help. To avoid perpetuating this situation in research on medicinal products, it is necessary to engage autistic adults and carers of autistic children as active participants and decision-makers on ethics committees, project planning teams and steering groups, in the research process itself, and in discourse concerning results and their interpretation. Researchers should avoid arrangements where autistic people’s involvement is limited to taking the medication and answering pre-set questions defined by the researcher on a limited number of occasions.
It is particularly important that autistic people become involved in the development of functional scales for the assessment of efficacy, since these should reflect the goals, criteria and subjective experiences of well-being that autistic individuals consider important, not externally defined measures of functioning only. Whenever possible, results of research should be published in a form accessible to autistic individuals and their advocacy organizations, e.g. as open access articles, to prevent autistic people being excluded from discourse concerning their interests because of poverty or other effects of disability.
