Outcome Measures

Primary Outcomes (1)

  • Change in seizure frequency at 6 months of maintenance

    The effectiveness of adjunctive ASM is measured as change in seizure frequency at 6 months of maintenance compared to baseline

    At 6 months of maintenance compared to baseline

Secondary Outcomes (9)

  • Change in seizure frequency at 3, 9, 12 months of maintenance

    At 3, 9, 12 months of maintenance compared to baseline

  • 50, 75, 90 Percent Responder rate

    At 3, 6, 9, and 12 months of maintenance phase.

  • 100 Percent Responder rate

    At 3, 6, 9, and 12 months of maintenance phase.

  • Retention rate

    At 3, 6, 9, and 12 months of maintenance phase.

  • Anxiety assessment

    At baseline, immediately after completion of titration, at 3 months, 6 months, and 12 months of maintenance phase.

  • +4 more secondary outcomes

Study Arms (1)

Adult patients with focal-onset seizures starting a treatment with ASM as adjunctive therapy

Adult patients having focal-onset seizures not adequately controlled despite a history of treatment with at least 2 ASM. The patients should be eligible to start a treatment with ASM as adjunctive therapy.The patients will be prospectively observed up to 12 months after having completed the related titration.

Other: ASM as adjunctive therapy

Interventions

ASM approved as adjunctive therapy

Adult patients with focal-onset seizures starting a treatment with ASM as adjunctive therapy

Sampling MethodProbability Sample
Study Population

Adult patients with epilepsy having focal-onset seizures with or without secondary generalization not adequately controlled despite a history of treatment with at least 2 anti-seizure medications and who will meet all the inclusion and none of the exclusion study criteria. The patients should be eligible to start a treatment with ASM as adjunctive therapy according to the physician's judgement, that must be clearly separated from the physician's decision to include the patient in the current study. The patients will be prospectively observed up to 12 months after having completed the related titration.

You may qualify if:

  • Male and female patients of any ethnic origin ≥18 years old at baseline.
  • Patients with diagnosis of focal-onset seizures with or without secondary generalization.
  • Patients should have clinical history of treatment failure with at least 2 ASMs.
  • Patients using their seizure diary as part of their standard of care for at least 3 months prior to -the study entry (diary can be paper or electronic, filled in by patient and/or family members).
  • Written informed consent (including data privacy consent) signed by the patient, legal guardian, or legally authorized representative prior to entering the study in accordance with the ICH GCP guidelines

You may not qualify if:

  • Patients who meet any of the contraindications to the administration of adjunctive ASMs according to their approved SmPC.
  • Progressive neurological disease, including degenerative CNS diseases and progressive tumors.
  • Patients with unstable psychiatric diagnosis that may confound participants' ability to participate in the study or that may prevent completion of the protocol-specified assessments (e.g., in the judgement of the Investigator, pose an appreciable risk for suicide, including suicidal behavior and ideation within 6 months prior to enrollment, current psychotic disorder, acute mania).
  • Evidence of clinically significant disease (e.g., cardiac, respiratory, gastrointestinal, renal disease) that in the opinion of the Investigator could affect the participant's safety or interfere with study assessments.
  • Patients with substance abuse or dependence (except for caffeine and nicotine).
  • Patients participating in any pharmacological or nonpharmacological interventional study within 30 days prior to baseline.
