Clinical Trial Summary
Children with West syndrome are prone to refractory seizures with poor neurocognitive outcome
overall. The current standard of care consists of treatment with ACTH, but the grade of
evidence is not high and not much RCTs are available. Ketogenic diet is an effective and well
tolerated treatment option in drug refractory epilepsy and also in refractory west syndrome.
In view of minimal side effects, better cost parameters and ability to continue for a longer
duration our study aiims to investigate the efficacy of ketogenic diet as a first line
therapy in comparison to ACTH therapy. Children with west syndrome after satisfying the
inclusion and exclusion criteria will be randomised into the two treatment arms and primary
response will be noted at the end of 6 weeks of therapy in terms of mean percentage of spasm
reduction.
Description:
- Consecutive children with West Syndrome (clinical spasm with EEG correlate) will be
screened in the study centre for eligibility, and after applying inclusion and exclusion
criteria they will be worked up for etiology.
- History will be taken and clinical examination will be done and if either are suggestive
of any underlying etiology specific investigations will be performed as indicated (Ex.
Neurocutaneous markers in tuberous sclerosis).
- If there are no other etiological pointers available from history and examination or if
there is any history suggestive of adverse perinatal events, MRI brain with epilepsy
protocol will be done.
- If MRI is not suggestive of structural etiology they will be given a vitamin
trial(pyridoxine 30mg/kg/day, pyridoxal phosphate- 20mg/kg/day, biotin 10mg/day and
folinic acid 15mg/day) for a period of 10 days for response. Those who respond to
Vitamin trial will be excluded from the study.
- Written informed consent will be taken from legal guardians who are willing to
participate in the study. Their anti-epileptic drugs will be optimised. Inappropriate
AEDs like phenytoin, phenobarbitone and carbamazepine will be discontinued and replaced
with valproate/levetiracetam and clonazepam in adequate doses and will be made in tablet
form.
- There will be an observation period of 2 weeks where the participants will be sensitised
about proper counting of spasms and the mean no. of spasms per week of the 2nd week will
form the baseline and they will be randomised into two groups as mentioned above during
the same period with no further changes in AEDs till the duration of completion of
primary objective. Those who require hiking/titrating of AEDs during the initial period
of 6 weeks plus run in period of 2 weeks will be treated as deviates and excluded from
the study.
- DASII will be administered by child psychologist and will be repeated at 3 months and at
6 months of followup wherever feasible.
- Appropriate screening for Tuberculosis as per unit protocol (Mantoux and CXR screening)
will be done if going to the ACTH therapy arm.
- Workup for ketogenic diet will also be done ECG, RFT, LFT, CBC, Lipid profile, Urine
calcium creatinine ratio and USG KUB for nephrocalcinosis if going to the KD arm
Group 1 ACTH arm:
- Children randomised into ACTH arm will be started on high dose regimen(45)(46) of
150U/m2 or 6U/kg of ACTH.
- This high dose will be continued for 2 weeks following which they will be slowly tapered
over remaining 4 weeks, for a total treatment duration of 6 weeks.
- EEG will be done at 6 weeks and 3 months of therapy in case of clinical spasm cessation
and wherever clinically indicated
- First followup will be at 6 weeks of treatment initiation, then at 8 weeks and from then
on once a month for a minimum period of 3 months (+/- 7 days) upto 6 months(+/- 7 days)
wherever feasible.
- Those who have had complete electroclinical spasm cessation will be continued of oral
AEDs.
- Those who have <50% spasm reduction rate will be shifted to KD.
- Those who have >/=50% spasm reduction rate will be given trial of other oral AEDs as per
protocol.
- The overall spasm reduction will be calculated from the mean number of spasms from the
observation period week and the mean number of spasms from the 6th week of therapy.
Adverse effects will be noted down in their seizure diary.
- For sustained electroclinical cessation those who had complete electroclinical response
will be rechecked at the end of 3 months (+/- 7 days) upto 6 months(+/- 7 days) wherever
feasible.
- Compliance rate, adverse events, >50% spasm reduction rate, clinical spasm cessation
rate, complete electroclinical spasm cessation rate will also be calculated from patient
seizure log and EEG correlate.
- RBS and BP monitoring to be done twice weekly
Group 2 KD arm:
- Children randomised into this arm will be admitted in ward and initiated on Ketogenic
diet under supervision.
- KD will be initiated in a ratio of 2:1 and then hiked to 2.5:1 in the next day and
subsequently to 3:on day 3. Urine ketones will be checked daily using ketone dipsticks.
- For better assurance of ketosis and tolerance the indigenous KD will be supplemented
with readymade formula for the initial period of 4 weeks and then shifted to complete
indigenous KD gradually over 1 week.
- If ketosis is not achieved by day 5 of starting KD, the ratio will be hiked to a maximum
of 4:1 from day 6.
- Patient will be discharged as soon as the desired ratio of KD is achieved, and the
parents are adequately motivated and confident. Telephonic contacts will be made in
regular intervals to further ensure compliance at home.
- Those children who are unable to tolerate taking adequate ketogenic diet therapy
requiring discontinuation of therapy, will be considered as deviates.
- The overall spasm reduction will be calculated from the mean number of spasms from the
observation period week and the mean number of spasms from the 4th week of therapy.
- Failure of KD: Children with response rate if not >50% spasm reduction by 6 weeks or no
electroclinical cessation of spasm by 3 months, will be considered to have failed KD and
shifted to standard ACTH therapy as per protocol.
- KD will be continued if there is more than 50% spasm reduction.
- EEG will be done at 6 weeks and 3 months of therapy in case of clinical spasm cessation
and wherever clinically indicated
- First followup will be at 6 weeks of treatment initiation,8weeks and then once monthly
for a minimum period of 3 months and 6 months wherever feasible. For sustained
electroclinical cessation those who had complete electroclinical response will be
rechecked at the end of 3 months (+/- 7 days) upto 6 months(+/- 7 days) wherever
feasible.
- Compliance rate, adverse events, >50% spasm reduction rate, clinical spasm cessation
rate, complete electroclinical spasm cessation rate will also be calculated from patient
seizure log and EEG correlate. .
- Formula based KD would be supplied to the patient free of cost. But the company will
play no part in the study design, conduct, data collection or analysis
