Brief summary:
The goal is to see whether topiramate (an anti-epileptic agent) improves the outcome of babies with neonatal hypoxic encephalopathy who are receiving whole body cooling.

Detailed description:
Hypoxic ischemic encephalopathy (HIE) is a devastating and unexpected disease in newborns that affects 1.5-2.6 per 1000 live births. Hypoxic ischemic encephalopathy has a mortality rate of up to 30% and survivors are at significant risk for adverse long-term outcomes, including seizures, cerebral palsy, and developmental delay. The investigators propose a randomized controlled study comparing therapeutic hypothermia alone, or therapeutic hypothermia combined with topiramate. The investigators hypothesize that adjuvant therapy with topiramate will reduce short term severity of HIE including seizures (the primary outcome), a composite HIE severity score, and reduce the time of normalization of the amplitude integrated EEG (aEEG). The investigators further hypothesize, that it will improve longer term outcomes such as developmental outcome. The primary hypothesis is that seizures before hospital discharge (or before 4 weeks post-natal age (which ever is earlier)) will be significantly reduced in the topiramate group compared to the control group

Arms: arm 1: Subjects will receive the standard of care intervention for HIE at our institution (whole body cooling for 72h followed by gradual rewarming) arm 2: In addition to whole body cooling, infants assigned to the topiramate group will receive 5mg/kg of topiramate daily enterally for a total of 5 doses. The first dose will be administered as soon as possible on admission.
Interventions: intervention 1: Topiramate intervention 2: Placebo
Intervention descriptions: intervention 1: Infants assigned to the topiramate group will receive 5mg/kg of topiramate daily enterally for a total of 5 doses. The first dose will be administered as soon as possible on admission. intervention 2: A placebo identical in appearance to the active agent (topiramate)

Title: Topiramate for infants receiving whole body cooling in neonatal 
encephalopathy  
Protocol Version Date: May 25th, 2018  
2) Objectives 
a) Specific Aims: To determine the effect of adjuvant topiramate treatment on the 
outcome of newborns with perinatal depression (including neonatal 
encephalopathy) who are already receiving the therapeutic whole body cooling. 
b) Hypotheses: We hypothesize that adjuvant therapy with topiramate will reduce 
short term disease severity in infants with neonatal encephalopathy/perinatal 
depression who are receiving whole body cooling. Specifically, we hypothesize 
that adjuvant topiramate will reduce the incidence of seizures (the primary 
outcome) in these infants. Secondary objectives include assessing the effect of 
that adjuvant topiramate in infants with neonatal encephalopathy/perinatal 
depression on biochemical markers of neuronal damage (serum UCHL1/ urine 
S100ß levels), a composite score of aEEG/cEEG abnormality, and on 
developmental outcomes at 9m, 18m and 27m. 
c) Scientific Problem: Neonatal encephalopathy is a devastating and unexpected 
disease in newborns that affects 1.5 to 2.6 per 1000 live births (Kurinczuk 2010). 
Neonatal encephalopathy has a mortality rate of up to 30% and survivors are at 
significant risk for adverse outcomes, including seizures, cerebral palsy, and 
neurodevelopmental delay. Until recently, only supportive care could be offered 
to these infants, and no therapy was available to modify the natural history of the 
disease. However, therapeutic hypothermia, or whole body cooling, has been 
shown to be beneficial for these infants. Hypothermia reduces mortality and 
decreases the risk of moderate to severe handicap in survivors. (Shankaran 2005). 
Although whole body cooling is effective at reducing the mortality and 
morbidity of neonatal encephalopathy/perinatal depression, the long-term 
outcome for such babies remains poor. For example in a recent NICHD funded 
study, whole body cooling reduced the rate of death but had no significant effect 
on long-term neurodevelopmental outcome of the survivors or moderate or severe 
disability from 62% to 44% (Shankaran 2012).  
As the number of surviving newborns with neonatal encephalopathy undergo 
cooling increases there is an urgent need for additional pharmacological 
intervention to improve their outcome. A recent study reviewed Erythropoietin 
(Epo) as potential neuroprotective therapy in newborns undergoing whole body 
cooling if given in the first 1-2 weeks of life. This study was a Phase I/II Clinical 
Trial, “NEATO”, which revealed that when Epo was given with hypothermia it’s 
dose achieved/exceeded concentrations that are known to be neuroprotective in 
animals (Wu 2013). A more recent study, “HEAL”, high-dose erythropoietin for 
asphyxia and encephalopathy, found similar results that high dose Epo given with 
hypothermia for neonatal encephalopathy may result in less MRI brain injury and 
improved motor function by 1 year (Wu 2016).  
These new results of present studies are rather interesting; yet there still 
remains potential for further exploration being that we have not started utilizing 


PROTOCOL TITLE: Topiramate for infants receiving whole body cooling in neonatal 
encephalopathy

these newer findings in our routine care/treatment of neonatal encephalopathy. It 
is imperative that continuing studies investigate any other potentials therapies that 
could be neuroprotective and improve neurodevelopmental outcomes in the long-
term for these infants undergo whole body cooling.  
 
3) Background 
The demonstration that a post-hoc intervention (i.e. beginning after the initial 
CNS insult) such as whole body cooling, can have beneficial effects has generated 
increased interest in the use of other adjuvant neuroprotective therapies in newborns 
receiving therapeutic hypothermia. Several potential adjuvant therapies are 
currently under investigation to improve the outcome of these babies. 
Erythropoietin for example has demonstrated potential neuroprotective effects (Wu 
2012/2016).  
We propose to study the adjuvant use of topiramate. We have selected this agent 
for several reasons:  
1. There are sound theoretical reasons why topiramate would be expected 
to improve outcome in neonatal encephalopathy. Neuronal damage following an 
ischemic event occurs in two waves, and glutamate plays a central role in both of 
these. Indeed, CSF glutamate levels in neonates following neonatal 
encephalopathy are strongly predictive of the degree of long-term impairment. 
Topiramate is effective at reducing glutamate release and this appears to be its 
prime biochemical action (Follet 2004). 
2. There is encouraging animal data on the effectiveness of topiramate in 
rodent (Noh 2006, Sfaello 2005) and porcine (Schubert 2005) models of neonatal 
encephalopathy, and topiramate may increase the therapeutic time window for 
initiation of therapeutic hypothermia (Liu 2004). 
3. There is good data on the safety of topiramate in neonates, including 
those with neonatal encephalopathy receiving whole body cooling. Topiramate is 
a widely used anticonvulsant in neonates (Novotny 2010). It has gained 
widespread acceptance because unlike phenobarbital and phenytoin (the 
traditional first-line agents), it does not lead to apoptosis in developing brain. A 
survey in 2008 (Silverstein) found that 55% of pediatric neurologists recommend 
topiramate for the treatment of neonatal seizures. Infants with neonatal 
encephalopathy and whole body cooling are a particularly high-risk group of 
neonates and both the underlying disease state (perinatal depression) and the 
treatment (whole body cooling) could alter the pharmacokinetics of topiramate. 
However, there is now good published peer-reviewed evidence of the 
pharmacokinetics of topiramate in neonates with neonatal encephalopathy who 
are being treatment with whole body cooling (Filippi 2009). Based on this data a 
safe and effective dose of topiramate was determined. Furthermore, there is also 
good peer-reviewed data on the safety of topitimate in neonates with neonatal 
encephalopathy who are being treated with whole body cooling (Filippi 2010), 
receiving doses used in the previous pharmacokinetic study. 
Although we now have good evidence on the appropriate dose of topiramate in 
newborns with neonatal encephalopathy/perinatal depression receiving whole body

cooling, and data on its safety, there is currently no published data on its efficacy in 
human newborns. The proposed study aims to address that deficit.

5) Study Timelines 
 We expect to complete this study within 2 years. We have 13 patients already 
enrolled and our goal is 42 total (study arm n=21 and control arm n=21). We have 
chosen a sample size of 42 as this sample size will have an 80% chance of detecting 
a reduction of seizure rate by 2/3 with a p-value of 0.05.  
 At our institution alone we have ample experience in whole body cooling having 
cooled 31 patients in 2015, 28 patients in 2016, and most recently 26 patients in 
2017. Patients will be asked to come for a one hour follow up outpatient clinic 
(MIND Institute) visit at the at 9, 18, and 27 months of age (all infants who receive 
cooling are asked to complete this follow-up, including those not in this study). 
 
6) Study Endpoints 
  
Our primary study endpoint remains to conclude if our current modality of whole-
body cooling coupled with topiramate results in seizures or no seizures.  
As well to determine the effect of adjuvant topiramate treatment on the outcome 
of newborns with perinatal depression (including neonatal encephalopathy) who are 
already receiving the therapeutic whole body cooling. 
 
7) Informed Consent 
One or both parents of the eligible infants are approached either 
(1) In person in the NICU at UCDMC by one of the investigators 
(2) By our Transport Nursing staff or Neonatal Fellow (if they are still at the 
outside referral center)  
In either case, the details of the study its risks and potential benefits will be 
explained by an investigator, and the parents are allowed to make an informed choice as 
to whether or not they decide to participate. If patient is transported the parents will be 
supplied with a copy of the consent form by the transport team and then contacted 
directly by an Investigator or when they arrive to our NICU.  
- 
Provide the consent form in person, give prospective subject sufficient time to 
review the consent form and discuss with friends/family. 
- 
Consent forms will also be given to the parents by the neonatology transport team 
and contacted directly by an Investigator.  
 
8) Procedures Involved 
This is a randomized double blind placebo controlled trial of newborns with 
neonatal encephalopathy undergoing our standard clinical protocol of whole body 
cooling. We will approach the parents of eligible infants, describe the study to them, and 
ask if they want their baby to participate in the study. Infants will be randomized by 
UCDMC pharmacy to receive cooling with placebo (control arm, n=21) or cooling with 
topiramate (study arm, n=21). At UC Davis, whole body cooling is a standard treatment 
for all infants with neonatal encephalopathy.  
     Active cooling will begin as soon as an infant is admitted to our NICU, using whole 
body cooling with a goal core temperature of 33.5 degrees Celsius and will be continued 
for 72 hours. Subject temperature will be monitored continuously using a rectal 
temperature probe and skin integrity is monitored closely with frequent turning of the

encephalopathy

infant. After 72h of cooling, babies are slowly rewarming back to normal body 
temperature over a period of 12h. 
     Infants assigned to the topiramate group will receive 5mg/kg of topiramate daily 
enterally for a total of 5 doses. This is the minimum therapeutic dose of topiramate for 
infants. The first dose will be administered on the day of enrollment and will continue 
through and after rewarming.  The duration of drug administration was chosen to 
encompass the cooling period as well as a brief period after rewarming is complete as this 
is a period where some infants develop seizures and display more signs of neurological 
damage. The control group will receive a placebo instead of topiramate. Pharmacy will 
prepare and send to NICU the placebo or study drug solutions in a way to be similar in 
appearance and volume. Initiation of cooling will not be delayed, but families will be 
approached for consent as soon as possible after cooling has started. 
      The cooling protocol includes a range of laboratory evaluations which will be carried 
out irrespective of whether the patient is enrolled in the study. These include: complete 
blood count, PTT/INR, DIC panel, complete metabolic panel, ammonia, lactate, troponin-
I, CK panel, blood gas, and urinalysis at the initiation of cooling and then every 24h until 
rewarming is complete (unless the Attending Neonatologist decides that more frequent or 
less reassessments are needed clinically). Blood gases, blood glucose and ionized calcium 
levels are measured at the initiation of cooling and then every 6h until rewarming is 
complete. Once labs have normalized per the discretion of the covering Attending some 
of these labs may be discontinued. These lab values will provide important data of the 
severity of each infant’s hypoxic-ischemic insult and for patient safety monitoring 
including information on liver function, kidney function, ammonia toxicity, metabolic 
status, and acidosis. Enrollment in the study will not change the frequency of these 
assessments.  
    A single channel EEG recording (an amplitude EEG, aEEG) or continuous video EEG 
is recorded continuously on all patients until rewarming is complete. This method 
measures the degree of encephalopathy and detects seizures. 
    The Pediatric Neurology service is by protocol consulted on all cooling patients. They 
will evaluate the infant and determine a neonatal encephalopathy score daily under the 
supervision of our Pediatric Neurologists. The presence of clinical seizures will be noted 
based on review of the bedside aEEG or cEEG.  The aEEG/cEEG data will be reviewed 
in 3 hour increments and document the time when the voltages on the aEEG/cEEG first 
return to normal. The aEEG/cEEG is used throughout the cooling phase and is generally 
discontinued after rewarming is completed but may be continued longer for abnormal 
tracings such as seizures at the discretion of the Neonatology Attending. In addition, the 
Attending Pediatric Neurologist will assess quality of movements, posture, reflexes, and 
muscular tone, each infant’s neurologic status will be categorized as normal (completely 
normal neurologic status), unspecific signs (eg, asymmetric muscle tone or reflexes) or 
abnormal with lack of reflexes and bilateral muscular hypotonia or hypertonia. 
      Additional tests in infants enrolled in this research study include: serum UCHL1 and 
urine levels of S100β, both will be measured at enrollment, at the start of rewarming, and 
at one-week of life. Topiramate trough drug levels will be collected 24 hours after the 
first, third, and fifth doses. The drug levels will be run by the UCDMC laboratory. These

encephalopathy

are the only additional laboratory assessment that study infants will receive as a result of 
taking part in the study. 
     All infants on the cooling protocol, irrespective of the research study, will have an 
MRI with spectroscopy on day 5-7 of life.  For this study, these images will be read by a 
single radiologist, our collaborator Dr. Bobinski of Neuroradiology. The reporting of 
MRI and MRS results will be standardized in conjunction with Dr. Bobinski to create a 
more consistent scoring method. 
     Following discharge, each infant will receive long-term developmental follow-up 
through the MIND clinic our High Risk Infant follow-up clinic. Infants will be seen at 
approximately 9, 18, and 27 months. The infants will have standardized Bayley Scale of 
Infant Development (BSID) III neurodevelopmental screening at these clinic follow-ups 
supervised by Dr. Catherine Rottkamp.   
The BSID-III contains 3 domains: cognitive, language (receptive and expressive 
communication), and motor (fine and gross motor). The cognitive scale includes items 
that assess sensory perceptual development, exploration and manipulation, object 
relatedness, concept formation, memory, and other aspects of cognitive processing. To 
allow comparison of results from the 3 domains, a composite score is calculated for each 
domain (mean, 100). A composite score below -2 SD (<70) is considered a severe delay 
for all domains. A Pediatrician will assess the quality of movements, posture, reflexes, 
and muscular tone at each clinic visit. Each infant’s neurologic status will be categorized 
as normal gait and walking, unspecific neurological signs (eg, asymmetric muscle tone or 
reflexes, muscular hypotonia), or abnormal with upper and/or lower extremities muscular 
hypertonia (signs of cerebral palsy (CP) present). 
 
9) Data and/or Specimen Management and Confidentiality  
 
Power Calculation 
 
Our primary hypothesis is that topiramate will reduce the frequency of early 
seizures (i.e. before hospital discharge). From our current data, 64% of infants have 
seizures prior to hospital discharge; a sample size of 42 will have an 80% chance of 
detecting a reduction of seizure rate by 2/3 with a p-value of 0.05.  
 
Statistical Methods 
 
Our primary outcome is that seizures before hospital discharge will be 
significantly reduced in the topiramate group compared to the controls. This will be 
assessed by nominal logistic regression with the presence or absence of seizures as the 
nominal dependent variable, and treatment group (topiramate or control) as an 
independent variable. Other independent variables will include those that are unbalanced 
between the treatment groups at randomization, and factors that could affect the risk of 
seizures (these would include neonatal encephalopathy score at study entry, time to 
initiation of cooling (< or ≥ 3h), gender etc). 
 
The effect of treatment assignment on neonatal encephalopathy score (measured 
daily) will be assessed by repeated measures ANOVA with neonatal encephalopathy 
score as the dependent variable, time and treatment assignment as the independent 
variable, and addition independent variables included as appropriate (see above). Time to 
normalization of aEEG/cEEG in the two different groups will be assessed by Kaplan-


PROTOCOL TITLE: Topiramate for infants receiving whole body cooling in neonatal 
encephalopathy

Revised: February 12th, 2018 
Meier analysis. The effect of treatment on S100ß levels in the urine or UHCL1 in the 
blood and on other markers of tissue injury will be compared using ANOVA (for 
outcomes measured once) and by repeated measures ANOVA for those measured on 
more than one occasion, at predetermined times. 
 
Effect of treatment assignment of development assessments will be assessed 
individually at the 9m, 18m and 27m examinations. 
 
All tests will be considered significant at p<0.05. Where necessary, Tukey-
Kramer’s test will be used to account for multiple comparisons 
 
 
Data Specimen/Management  
 
 
Data specimens will be stored in the NICU and numerically coded, only those 
who are involved with this study will have access to the specimens. The specimens will 
only be stored for the duration of the study and thereafter discarded. 
 
10) Data and/or Specimen Banking  
 
 
There is no plan for specimen or tissue banking in the future.   
 
11) Provisions to Monitor the Data to Ensure the Safety of Subjects 
To monitor the safety of each newborn we will track the following variables closely 
during the intervention: blood gases, blood pressure (hypotensive episodes and required 
interventions), evidence of seizure activity, and serum topiramate levels. This study is 
only applicable to newborns with neonatal encephalopathy admitted to the NICU at UC 
Davis for cooling therapy. Neonatal encephalopathy is a life threatening disease with 
30% chance of death and 64% chance of seizures during the neonatal period. These 
patients receive 24 hours daily continuous extremely close physiological and biochemical 
monitoring based on their underlying disease state. 
 
A Data Safety Monitoring Committee (DSMC) will be utilized for this study. A 
report will be sent to the chairman of the DSMC every 6 months. He will share this with 
the other members and meetings will be carried out either by e-mail or face-to-face as the 
chairman sees fit. The DSMC will remain blinded to study assignation, but will receive 
summary data for every patient including which agent the patient received (designated as 
"Study drug A" or "Study drug B"), their short term outcome (incidence of seizures and 
survival to hospital discharge) and the number of doses of sodium bicarbonate and 
bronchodilators they received (in order to assess for an increased need for these 
medications). If the DSMC identifies any trend (P<0.1) towards more seizures, reduced 
survival, an increased need for sodium bicarbonate or bronchodilators they will be 
allowed to unblind themselves. If the trend is for increased short term need for sodium 
bicarbonate or bronchodilators, decreased survival or increased seizures in the topiramate 
group they will be allowed to stop the trial if they wish. However, if the trend favors 
topiramate over placebo, the DSMC will be expected to allow the trial to continue. 
 
Below are the list and qualifications of DSMC Members: Francis Poulain 
(Neonatology Attending), Sandra Ellingson (Neonatal Nurse Practitioner), and Andrew 
Lee (Clinical Pharmacist).

This protocol has risk category 2; namely “research involving greater than minimal risk, 
but presenting the prospect of direct benefit to the individual subjects.” As such we 
have developed an adverse event grading scale that is detailed below: 
 
1. Adverse Event (AE) Grading and Attribution Scale 
 
If adverse events should occur, they will be assessed using the following grading 
scale: 
0= No adverse event or within normal limits 
1= Mild adverse event 
2= Moderate adverse event 
3= Severe and undesirable adverse event 
4= Life-threatening or disabling adverse event 
5= Death caused by adverse event 
Should adverse events occur, the following Attribution scale will be used to 
determine the relationship of the adverse event to the study.  
- 
Unrelated - AE is clearly not related to the study procedure /intervention/-
agent 
- 
Unlikely - Relationship to the study procedure/intervention/agent appears to 
be remote because the factors described with "Probable" and "possible" 
classification are missing and other factors suggest an alternative etiology 
exists; such as environmental factors, including common infectious diseases. 
- 
Possible - One or more of the above factors suggest a possible relationship to 
the use of the study procedure/intervention/agent, but other etiologies seem 
equally or more likely. 
- 
Probable - Relationship to the study procedure/intervention/agent seems 
probable because of such factors as a clear temporal association with the 
interaction or scanning process; lack of alternative explanations for the 
experience; or other factors. 
- 
Definite - AE is clearly related to the study procedure /intervention/agent. 
2. Plan for Unanticipated AE and SAE Reporting 
Any serious or unsuspected adverse events will be reported to the Data Safety 
Monitor Committee (DSMC) and the IRB within 72 hours of the occurrence, or 
immediately if the event is fatal or life threatening.  
3. A Plan for Annual Reporting of AEs 
 
The Principal Investigator will provide an annual patient safety progress report to 
the IRB, and a twice annual report to the DSMC.  
4. Plan for Safety Review 
 
This study will be reviewed by an independent data safety monitoring committee. 
The committee DSMC (as described above) will review recruitment, safety and efficacy

data every 6 months. In addition, the chair will receive copies of all adverse events and 
may call an additional meeting, based on the reports received. 
The responsibilities of this monitor will include:  
- 
Periodic analysis of the safety of the experimental therapy.  
- 
Review the research protocol, all informed consent documents, and plans for 
data and safety analysis.  
- 
Evaluate the progress of the intervention, including periodic assessment of 
data quality and timeliness of data entry, participant recruitment, accrual and 
retention, and any other factors that may affect the study outcome.  
- 
Review any factors external to the study when relevant, such as scientific or 
therapeutic developments that may have an impact on the safety of the 
subjects or the ethics of the trial. 
 
12) Withdrawal of Subjects 
Babies will be ineligible if they have major congenital abnormalities. If the baby 
had a proven (i.e. electrically confirmed seizure) prior to enrollment they would not  
be eligible for the study. If a seizure occurred after enrollment/ randomization but before 
the first dose of study medication the protocol would continue based on the intention to 
treat. Treatment of seizures will be guided by our Pediatric Neurologists (who will be 
unaware of treatment assignment). Currently we do not use topiramate for treatment of 
seizures, and do not intend to change our management of seizures in the foreseeable 
future. Our first line treatment is phenobarbital, second line is levetiracetam, and the third 
line treatment is ativan. So, any baby who developed seizures during the protocol would 
receive our current standard of care, but continue to be in the study. The study protocol 
will not change the management of seizures should they occur. Once enrolled, a baby 
would not be withdrawn because of seizures (irrespective of number). We would manage 
these seizures according to our current clinical practice (see above). Although our  
primary endpoint (seizures) has been met, we would continue to collect data on 
secondary endpoints and on safety measures. Patients with renal deficiency (creatinine >2 
mg/dL) and liver failure (ammonia >100mcmol/L) will not be eligible for the study. 
 
13) Risks to Subjects 
Newborns with neonatal encephalopathy are very vulnerable. Given the high risk of 
lifelong neurologic injury and the low risk of the proposed intervention, the risk to 
benefit ratio of this study is reasonable. Every effort will be made to ensure that the 
infants receive excellent care and that the parents of the infants fully understand the 
benefit/risk of the study. Topiramate has been extensively used to treat variety of 
neurological diseases including seizures in adults, children, and infants. It is a widely 
used drug with minimal side effects. In adults, topiramate can cause side effects not likely 
to be obvious in neonates (e.g. paresthesias, dizziness, fatigue, drowsiness, depression, 
coordination problems, nausea, and difficulty concentrating). These should not be a 
problem in study infants as babies who receive whole body cooling are routinely sedated 
with morphine, and any additional sedative effect from topiramate is likely to be minor. 
Babies who receive whole body cooling are NPO so the possible side effect of nausea by 
topiramate should be be minimized.   


PROTOCOL TITLE: Topiramate for infants receiving whole body cooling in neonatal 
encephalopathy  
Page 12 of 15 
HRP-503-PROTOCOL TEMPLATE-General  
Revised: February 12th, 2018 
     Pharmacological, pharmacokinetic, and therapeutic studies of chronic administration 
of topiramate have been conducted to determine its effective dose and to demonstrate its 
safety in newborn infants (2,4,5). We propose the use of the minimum therapeutic dose of 
5 mg/kg/day topiramate for 5 days. However even side effects associated with long term 
(months) administration of topiramate to infants appear to be minimal. In this study, the 
serum level of the drug will be monitored in addition to arterial blood gases, blood 
pressure, and clinical evidence of seizure for any possible side effects. Several studies 
have used topiramate for treatment of epilepsy or neonatal encephalopathy in infants. In a 
recent large double-blind placebo controlled prospective study of different doses of 
topiramate as an adjunctive therapy to conventional antiepileptic drugs in infants a 10% 
increased rate of fever, diarrhea, vomiting, weight decrease, and viral infection was 
reported (15). These side effects were dose related and occurred only in infants treated 
with a higher dose (25 mg/kg/day) of topiramate.  
     Adverse effects of topiramate administration in this age and population of infants that 
are not published but have been reported to FDA include: viral infection, bronchitis, 
pharyngitis, rhinitis, otitis media, upper respiratory infection, cough, and bronchospasm. 
An increased risk for infections (any topiramate dose 12%, placebo 0%). Topiramate 
resulted in an increased incidence of patients with increased creatinine (any topiramate 
dose 5%, placebo 0%), BUN (any topiramate dose 3%, placebo 0%), and an increased 
incidence of decreased potassium (any topiramate dose 7%, placebo 0%). Monitoring of 
creatinine, BUN, potassium, and urine output is the standard of care in all patients with 
neonatal encephalopathy. The risk of viral infections is unlikely given the short duration 
of therapy. Many infants receiving whole body cooling may require mechanical 
ventilation due to their underlying disease so bronchospasm is unlikely, and easily 
treatable should it occur. 
     One concern on the use of topiramate is the potential to produce metabolic acidosis. 
From the data of Filippi (2010), although there were no significant effects of topiramate 
on metabolic acidosis, there was the suggestion in a post-hoc sub-group analysis that 
topiramate might increase metabolic acidosis in infants receiving deep hypothermia 
(cooled to 30-33 degrees Celsius) but not in those with moderate hypothermia. As we 
will be using moderate (not deep hypothermia) we do not foresee this as a problem. 
However, all infants undergoing cooling will have monitoring of their blood gases, and 
the detection of acidosis (especially metabolic acidosis) is common and easily treatable- 
sodium bicarbonate. Should this become a problem, we will therefore, be able to identify 
it early and respond to it promptly.  
    For severe adverse events, the drug will be discontinued and clinical intervention will 
be carried out. Any serious adverse events will be reported to the IRB immediately. 
     We will prospectively collect data on the number of doses of sodium bicarbonate each 
baby receives whilst receiving topiramate (or placebo), and the total number of doses of 
sodium bicarbonate received during their entire hospitalization. We will do the same for 
the number of doses of bronchodilators (for bronchospasm) the subjects receive. This 
information will be provided to the DSMC every 6 months for their review. 
Potential side effects relevant to the population of this study are also described in lay 
terms in the informed consent form.   
    We have enough theoretical and experimental evidence to believe that the benefit of 
using topiramate in this group of patient outweighs the risk.  


PROTOCOL TITLE: Topiramate for infants receiving whole body cooling in neonatal 
encephalopathy  
Page 13 of 15 
HRP-503-PROTOCOL TEMPLATE-General  
Revised: February 12th, 2018 
    Increased risk of brain injury can be detected by measuring the level of S-100 and 
UCHL1 in the urine/blood respectively in both groups of infants. Neurological 
examination at 18 month will identify infants in need of further follow up and/or 
intervention. 
    Therefore the risk-benefit ratio of this study is reasonable.  
 
14) Potential Benefits to Subjects 
Topiramate has been successfully used for treatment of epilepsy in infants, and has 
a good safety record for newborns with neonatal encephalopathy treated with whole body 
cooling. We have enough theoretical and experimental evidence to believe that the 
benefit of using topiramate in this group of patient outweighs the risk. There is potential 
benefit in using the drug for prevention of epilepsy and neurodevelopmental delay in 
these infants. Increased risk of brain injury can be detected by measuring the levels of 
S100ß levels in urine and UCHL1 in serum in both groups of infants. Neurological 
examination at 18 month will identify infants in need of further follow up and/or 
intervention. The risk-benefit ratio of this study is reasonable.

You are being asked to take part in this study because you have a newborn child with perinatal 
depression or neonatal encephalopathy who will receive whole body cooling upon admission to our NICU.  
 
We hope to learn more about perinatal depression, epilepsy and neonatal encephalopathy. Perinatal 
depression is a sign of poor brain function in the newborn shortly after birth that can be caused by many things 
one of which is neonatal encephalopathy. Neonatal encephalopathy is reduced blood and oxygen supply to the 
brain of a baby and can appear as over-activity, startling easily, floppiness, extreme sleepiness, coma, abnormal 
movements, reflexes or seizures. These are very serious problems for newborn babies and can lead to handicap 
and/or even death.  
 
We know that whole body cooling helps these babies; this procedure is used at UC Davis and 
nationwide. However, many babies still have problems and do poorly. Many of these infants develop seizures 
and a third of the surviving infants develop moderate or severe neurological disabilities.  
 
This study examines whether administration of an antiepileptic drug called topiramate helps babies with 
neonatal encephalopathy who receive whole body cooling. Topiramate is a drug that might limit damage to the 
brain while still letting the brain develop normally. However, it is not known whether it will really help babies 
with perinatal depression or neonatal encephalopathy.

The purpose of this research study is to find out whether topiramate will help babies with perinatal 
depression or neonatal encephalopathy, and whether it will reduce seizures (convulsions), quicken the recovery 
from perinatal depression/ neonatal encephalopathy, or improve long-term development. We also want to see 
whether a urine test called S100ß (marker for brain cell damage in the urine) and a blood test of UCHL1 
(marker for brain cell damage in the blood) will help us identify babies who are at more risk of seizures or poor 
development. S100ß and UCHL1 are released from damaged brain cells and may let us see which babies might 
be at highest risk in the future.   
General information about this research:  
• 
Participants will be in this study as long as the following: 
o You as Parents will be asked to have your baby participate for a period of 5 days in which the 
study drug/Topiramate or placebo is administered. You and your baby are also expected to come 
to our clinic for 1 hour follow up neurodevelopmental test when your baby is 9, 18 and 27 
months old. Participation in this study will not change the period of admission to our NICU and 
follow ups because infants with neonatal encephalopathy are usually in the hospital for several 
weeks and are all eligible for follow outpatient clinic visits. 
• 
The main risks of participation include the following: 
o Every baby taking part in the study will be watched carefully for any side effects. However, the 
Researcher may not know all the side effects or risks. Side effects may be mild or very serious. 
The Researchers may give the baby medicines to help lessen side effects. Many side effects go 
away soon after the baby stops taking the drug. In some cases, side effects can be serious, long 
lasting, or may never go away.  
o Side Effects:   
1. Increased risk of infection- viral infection, upper respiratory infection, bronchitis, 
pharyngitis, rhinitis, otitis media 
2. Cough 
3. Bronchospasm 
4. Fever  
5. Diarrhea  
6. Vomiting 
7. Weight decrease 
8. Renal Issues- increased creatinine (measure of kidney function), BUN (measure of 
kidney function), and decreasd potassium (electrolyte)  
9. Metabolic Acidosis (also a side of effect of whole body cooling) 
o Risks and side effects related to the minimum clinical dose of topiramate administered in this 
study are minimal. Topiramate may cause changes in the acid level in your baby's blood. 
However, these are checked for very carefully in all babies getting whole body cooling whether 
or not they are getting topiramate. If these changes happen, they are relatively easy to treat and 
many babies getting whole body cooling need these types of treatment whether or not they are 
getting topiramate. The extra amount of blood to be taken (less than 3 teaspoons) is small and 
much less than is needed to be taken for routine tests. It should not affect your baby. The urine 
collection involves using a cotton ball to collect the urine from the diaper area. It is safe, and 
should not affect your baby.

The following are the drugs you may receive during this research:  
 
 
If you as Parents allow your baby to be in this study, your baby may receive topiramate an anti-epileptic 
medication or a placebo.   
 
 
 
Topiramate is considered investigational in this study because the U.S. Food and Drug Administration 
(FDA) has not been approved this drug for use in patients with perinatal depression or neonatal encephalopathy. 
Topiramate is approved for use in patients with epilepsy. Topiramate will be given 5mg/kg daily enterally for a 
total of 5 doses. Parents or your baby’s insurance company will not be charged for the test drug.    
 
The risks of the drug described can be found above. 
 
How your baby will be assigned to either receive the study drug vs the placebo: 
 
 
The treatment the baby will get will be chosen by chance, like flipping a coin or drawing a number out 
of hat.  Your baby has a 50/50 chance of getting each treatment.  The study team and you will not and cannot 
choose which treatment you will get. The study doctor and you will not know which treatment your baby is 
receiving.  
 
The following procedures will be done for this research:  
 
 
If your baby takes part in this study, you as Parents will be asked to read and agree with the following: 
Parts of this study involve standard medical care. Standard care being what is normally done to prevent, 
diagnose, or treat a certain condition or illness. Other parts of this study involve the study drug or placebo.

or not your baby qualifies for the study.  
• Whole body cooling - your baby will be 
looked after on a cooling blanket that will 
lower their temperature to 33.5°C (92.3 
degrees Fahrenheit) for 72h. After this 
your baby will be slowly rewarmed back 
to a normal temperature  
• Continuous monitoring of your baby's 
brain wave activity to look for seizures 
(aEEG/cEEG) for 3-5 days by electrodes 
placed externally on the head  
• Vital signs - will be measured constantly 
for at least the first 4 days  
• Blood gases - will be measured every 6h 
(unless your Doctor thinks more or less 
frequent measurements are needed)  
• Blood chemistry- will be measured every 
24h (unless your Doctor thinks more or 
less frequent measurements are needed)  
• Blood glucose - will be measured every 
6h (unless your Doctor thinks more or less 
frequent measurements are needed)  
• Blood calcium - will be measured every

The following procedures WILL ONLY 
BE DONE IF YOUR BABY JOINS THE 
STUDY:  
• Your baby will be randomized to get a 
solution orally once a day for five days. 
The solution will either be topiramate or 
placebo.  
• A small amount of extra blood (about 1/2 
teaspoon) will be taken three times to 
measure a special protein (UCHL1) that 
may detect brain injury. This blood will 
be taken at the same time as your baby 
needs a routine blood test.  
• A small amount of extra blood (less than 
1⁄2 teaspoon) will be taken three times to 
measure the level of topiramate in your 
baby’s blood. This blood will be taken at 
the same time as your baby needs a 
routine blood test.  
• A small amount of urine (1 to 3 
teaspoons) will be collected from a cotton 
ball in your baby's diaper to measure a 
special protein (S100B) three times during 
the study.

occurred after enrollment/ randomization but before the first dose of study medication the protocol would 
continue based on the intention to treat.  
Treatment of seizures will be guided by our Pediatric Neurologists (who will be unaware of treatment 
assignment). Currently we do not use study drug topiramate as first-line treatment for seizures, and do not 
intend to change our management of seizures in the foreseeable future.  
If your baby develops seizures during the study he or she would receive our current standard of care, but 
will continue to be in the study. If your baby develops any issues with their kidneys or liver they will not be 
eligible for the study.
