February 28, 2023 updated by: M. Carmen Cabellos Minguez

Efficacy of Phenytoin in the Prophylaxis of Seizures of Patients With Pneumococcal Meningitis at Least 50 Yrs Old. A Multi-center Comparative Randomized Double-blind and Placebo-controlled Clinical Trial

To evaluate the efficacy of the prophylaxis with phenytoin in the prevention of seizures in patients with pneumococcal meningitis. Hypothesis: Administration of prophylactic phenytoin will reduce the incidence of seizures in patients with pneumococcal meningitis older than 50 yrs.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Background: Bacterial meningitis has still a high morbi-mortality despite the global improvement in therapy.

Among complications, the presence of seizures may contribute to increase the morbi-mortality. Prophylactic phenytoin is used in clinical practice in high risk patients but this use is variable because there are not controlled clinical trials demonstrating efficacy along with antibiotics and corticosteorids. Pneumococcal episodes are associated to a higher number of seizures and a higher mortality especially in elderly patients.

Objectives: To evaluate the efficacy of the prophylaxis with phenytoin in the prevention of seizures in patients with pneumococcal meningitis. Hypothesis: Administration of prophylactic phenytoin will reduce the incidence of seizures in patients with pneumococcal meningitis older than 50 yrs.

Methodology: Multicentre, randomized, double blind placebo controlled clinical trial. Patients will be included mostly from hospitals from REIPI and CAIBER and randomly assigned to receive phenytoin or placebo.

Sample size has been estimated in 61 patients per group. Antibiotic therapy and ICP prophylaxis will be standardized in all centres. Phenytoin administration will be maintained during antibiotic therapy. End point will be incidence of seizures during hospital stay and overall mortality will be a secondary end-point. Followup visits at 1 and 3 month will be performed.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

50 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

Adult patients > or = 50 years old.

Diagnosed of pneumococcal meningitis due to clinical characteristics plus a positive CSF Gram stain and/or a detection of pneumococcal antigen or PCR

or

Suspected pneumococcal meningitis since it is an episode related to otitis, pneumonia, sinusitis or pericranial fistula or in patients with known risk factors such as myeloma or splenectomy.

Exclusion Criteria:

To have seizures prior to arrive to the hospital or the inclusion in the study.

Pregnancy or breastfeeding.

To have conduction abnormalities in ECG.

History of allergy or intolerance to phenytoin.

Patients with meningitis as a complication of neurosurgical procedures.

Epileptic patients taking usually anticonvulsivants.

Refusal by the patient or family to participate and/or to sign the informed consent.

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available.

Placebo Comparator: placebo
placebo vials and pills labeled as phenytoin prophylaxis vials and pills
Drug: placebo
Placebo 18 mg /Kg/day iv as loading dose. 24 hours later placebo 6 mg/Kg/d in 3 divided doses iv shifting to oral route at the same dose when the patient is able to use oral route.

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
