Early Post-Traumatic Seizures Prevention Trial (E-PTS Trial)
Assessing Phenytoin and Levetiracetam Efficacy, Cost-Effectiveness, and CYP2C9/SV2A Polymorphism in Early Post-Traumatic Seizures: A Multicentric Prospective Randomized Trial
Early Post-Traumatic Seizures Prevention Trial (E-PTS Trial) (NCT07072624) is a Phase 4 interventional studying Seizures and Traumatic Brain Injuries, sponsored by All India Institute of Medical Sciences, Jodhpur. RECRUITING as of the most recent ClinicalTrials.gov update. Talk to your doctor before contacting the trial site.
About This Trial
Rationale/gaps in existing knowledge: The prophylaxis for post-traumatic seizures (PTS) remains controversial due to a lack of class I evidence. Investigators plan to conduct a high-quality, prospective, multicentric, randomized study regarding seizure prophylaxis in traumatic brain injury (TBI) with phenytoin, levetiracetam, and the placebo in three respective treatment groups, along with the effect of drug polymorphism on seizure occurrence. Novelty: Literature is scarce regarding the ideal management of early PTS in traumatic brain injury (TBI), a major public health problem. Further, no study has evaluated the effect of genetic polymorphism on seizure occurrence in traumatic brain injury. This Multicentric study will be the first of its kind, not only in India but also globally. Objectives: To evaluate the seizure incidence \& efficacy of the respective anti-epileptic drug in each treatment arm. Assessment of clinical \& functional outcomes, safety profile, and cost-effectiveness in each group. Effect of genetic polymorphisms on seizure incidence among study participants Methods: A Multicentric prospective randomized placebo-controlled double-blinded clinical trial is planned. After satisfying eligibility criteria and informed consent, TBI patients will be randomly allocated into three arms 'phenytoin arm', 'levetiracetam arm', and 'placebo'. Drug polymorphism will be analyzed in all the patients using quantitative real-time PCR. Expected outcome: This study will provide high-quality evidence in PTS management and will establish the role of prophylactic anti-epileptics in PTS. This study also opens the plethora of undesignated roles of genetic polymorphism in the efficacy and safety of levetiracetam and phenytoin in traumatic brain injury patients.
What Stage of Research Is This?
Phase 4 studies happen after a treatment has been approved by the FDA. They monitor long-term safety, real-world effectiveness, and any rare side effects that only emerge in larger populations over longer periods. Phase 4 results sometimes lead to label changes, additional warnings, or — rarely — withdrawal of approval.
This trial is currently recruiting participants. The sponsor has registered the study with ClinicalTrials.gov as actively enrolling, which means new applicants who meet the eligibility criteria can be considered for screening. Trial status can change between updates — confirm current recruiting status with the study contact before traveling for a screening visit.
A target enrollment of 1,260 participants makes this a sizable late-stage trial. Studies in this range typically have enough power to detect clinically meaningful differences from a comparator and to characterize less-common side effects.

Treatments Being Tested
Phenytoin
The Phenytoin group will be given a loading dose of phenytoin 20 mg/kg intravenously (maximum, 2 gm) at 50 mg per minute and then started on a maintenance dose (5-6 mg/kg/d, rounded to the nearest 100 mg, intravenously administered every 8 hours). The intravenous will be switched to oral once the patient is fit to take it orally or via Ryles tube. The oral dose would be a single 300 mg ER (extended-release) tablet per day. Both IV and/or oral doses of phenytoin will be given only for 1 week after head trauma. Patient= Patients with Traumatic brain injury as per eligibility criteria. Intervention= Phenytoin loading dose IV (20 mg/kg) followed by 100 mg IV TDS till patient accepts orally. Oral dose will be administered as a single 300 mg ER tablet per day. Both IV and oral phenytoin will be given for 1 week after traumatic brain injury and then stopped. Comparator= Matching Placebo
Levetiracetam
The Levetiracetam group will receive 25-30 mg/kg/d in two divided doses (rounded to 750 mg, administered intravenously every 12 hourly). The intravenous dose will be switched to oral form once the patient is fit to take it orally or via Ryles tube. The oral dose would be two tablets of 750 mg ER (extended-release) levetiracetam daily. Both IV and/or oral doses of levetiracetam will be given only for 1 week after head trauma. Patient= Patients with Traumatic brain injury as per eligibility criteria. Intervention= Levetiracetam IV dosing will be 25-30 mg/Kg/d in 2 divided doses (rounded to 750 mg IV BD) followed by 2 tablets of 750 mg ER once patient fit to take orally or via Ryles tube. Comparator= Matching Placebo.
Placebo
The Placebo group will be administered normal saline intravenously of similar amount that of intervention group and matching placebo tablets orally (double dummy) once the patient is fit to take orally. Similar to the intervention group, both IV and oral placebo will be given till 1 week after traumatic brain injury.

Who can participate in NCT07072624?
Eligibility for this trial depends on the specific inclusion and exclusion criteria set by the sponsor. The plain-English summary above translates the most important criteria into accessible language; the official clinical text is preserved in the collapsible section underneath. Whether you fit any specific trial is a medical decision your doctor needs to confirm — bring the trial information to your treating physician for a full review against your medical history.
How do I contact the trial site for NCT07072624?
Contact information registered with ClinicalTrials.gov is shown in the sidebar of this page. Before reaching out, confirm with your treating physician that this trial is appropriate for your situation. The trial site will then walk you through the screening process to determine final eligibility.
Is participating in a clinical trial safe?
Clinical trials in the United States are regulated by the FDA and overseen by Institutional Review Boards (IRBs) that review the protocol for safety. Risk varies by trial — Phase 1 studies test new treatments in humans for the first time, while Phase 3 trials use treatments that have already passed earlier safety screening. The informed consent document for any specific trial details the known risks and what to expect. Discuss those risks with your physician before deciding whether to participate.
