Clinical Trial Summary

The NeuralNET Cerebral Palsy Pilot Study is testing a genetic testing pathway in the NHS for children with cerebral palsy (CP). Other studies suggest that almost one in three peoples' CP is caused by a change in their genes, but more studies are needed to confirm this. A genetic test called whole genome sequencing (WGS) will be used for children who have CP to look for rare changes in genes that cause the condition, and the results of the test will be given to children's doctors within 12 weeks. Knowing that CP has a genetic cause could lead to changes being made to a child's care or treatment that could improve their condition. The study will test 66 children with CP from 3 hospitals, and also their biological parent(s), if they're available. Following informed consent, the investigators will collect a blood sample from everyone taking part which will be sent for WGS. It is important to understand what families think and feel about the testing. The investigators will ask parents/guardians of the children taking part to fill in two questionnaires, one before and one after WGS. Some parents/guardians will also be interviewed after getting the WGS result, to ask about their experience of the testing. The study will take up to 16 months per family. The results of this pilot study will tell the investigators if it is feasible for the NHS to use WGS to test children with CP. If so, a larger study testing more children with CP can then be carried out to help decide if this type of WGS-based testing should be made available through the NHS to children with CP whose clinical care might be changed by the result. The genetic findings from this study will also be made available to other researchers and doctors to do more research into CP that might help improve general understanding of the condition and its potential treatment.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Feasibility of rapid whole-genome sequencing of children with cerebral palsy	The investigators will measure feasibility of rapid whole-genome sequencing of children with cerebral palsy by successful delivery of WGS results to 66 children with a clinical diagnosis of CP within 12 weeks of blood sample receipt in the laboratory.	16 months
Secondary	Uptake of WGS testing by families with a child with CP	The percentage of uptake of WGS testing by families with a child with CP will be measured by comparing the number of families invited to the study to the number who proceed with testing at baseline	Baseline
Secondary	Reasons for declining offer of WGS	The reasons for declining the offer of WGS provided by families voluntarily to the referring clinician will be measured in aggregate using a questionnaire at the close of the recruitment	16 months
Secondary	Identification of specific genetic contributors to CP in the UK	Specific genetic contributors to CP in children in the UK will be measured using the collation of WGS results at the close of the recruitment	16 months
Secondary	Parent/guardian intolerance for uncertainty	Intolerance of uncertainty of parent/guardian will be measured with the short version of the validated Intolerance for Uncertainty scale, which is a 12-item self-administered questionnaire where items are rated on a 5-point Likert scale where a higher score means higher intolerance of uncertainty.	baseline
Secondary	Parent/guardian attitude to genome sequencing	Four-item scale via self-administered questionnaire examining general attitudes (eg harmful vs. beneficial, unimportant vs. important, etc.) of parent/guardian to genome sequencing measured on a five-point Likert scale, where a higher score means more positive attitude.	baseline and 16 months
Secondary	Parent/guardian decisional conflict	Parent/guardian decisional conflict will be measured with validated sixteen-item self-administered questionnaire which assesses decisional certainty or conflict about a healthcare decision on a five-point Likert scale, where a higher score indicates higher uncertainty or conflict.	baseline
Secondary	Parent/guardian empowerment	Parent/guardian empowerment relating to genomic medicine will be measured with the Genomics Outcome Scale, a validated six-item self-administered questionnaire with a 5-point Likert scale, where a higher score indicates higher theoretical construct of empowerment.	baseline, 16 months
Secondary	Parent/guardian decisional regret	Parent/guardian decisional regret about WGS will be measured with a validated 5-item self-administered Decisional Regret Scale, which uses a 5-point Likert scale where higher scores indicate greater decisional regret.	16 months
Secondary	Parent/guardian psychological impact of WGS	Parent/guardian psychological impact of WGS will be measured with adapted 10-item version of the validated Feelings About genomic Testing Results (FACToR) scale, which uses a 5-point Likert scale to measure agreement with specific feelings about the impact of result disclosure after genomic testing, where a higher score indicates greater agreement with those feelings.	16 months
Secondary	Impact of WGS on family quality of life	Impact of WGS on the family's quality of life will be measured using the Family Impact Module of The PEDS-QL, which is a 36-item validated self-administered scale. It uses a 5-point Likert scale where higher scores indicated greater agreement with specific items.	16 months
Secondary	Clinical utility of WGS testing in children with CP	The clinical utility of WGS testing in children with CP from the Paediatrician's perspective will measured using the validated Clinician-reported Genetic testing Utility InDEx (C-GUIDE), a self-administered questionnaire which includes 17 items related to results received for the primary indication for testing and 9 items related to secondary variant results received. Individual items scores range from -1 to 2. An item score >0 indicates positive utility, item scores <0 indicate presence of negative utility, and item scores of 0 indicate absence of utility.	16 months
Secondary	Number of candidate variants which warrant further investigation of pathogenicity	Number of candidate variants which warrant further investigation of pathogenicity via collaborative studies will be measured by collating potentially pathogenic variants of uncertain significance at the completion of the study.	16 months
Secondary	Generation of data to support the refinement of clinical criteria for WGS for CP	Data to support the refinement of clinical criteria for assessing CP patient suitability for WGS testing will be measured using the correlation of clinical features with identification of causative variants by WGS	16 months
