Brief Summary
The purpose of study EP0073 is to assess the long-term safety, tolerability, and efficacy during 5 years of treatment with the drug UCB0942 in patients with highly drug-resistant focal epilepsy. Also, the effects of UCB0942 on the patient's quality of life will be explored.

Primary Outcomes (20)
Percentage of Participants Experiencing at Least One Treatment-Emergent Adverse Event (TEAE) From the Beginning at Entry Visit (EV) of the Evaluation Period to End of Safety Follow-Up Visit During the EP0073 Study
An adverse event (AE) is any untoward medical occurrence in a patient or clinical investigation participant administered a pharmaceutical product that does not necessarily have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product. Percentage of participants experiencing at least one treatment-emergent adverse event (reported by the participant and/or caregiver or observed by the Investigator or inpatient staff) are reported.
From Entry Visit to End of Safety Follow-Up Visit (up to 5 years)
75% Responder Rate by 3-month Interval (Month 0 to 3) Over the Evaluation Period
A 75% responder is defined as a participant with a ≥75% reduction in partial-onset seizure (POS) frequency for observable focal-onset seizures relative to the 2-week Prospective Outpatient Baseline Period defined in EP0069. Observable focal-onset seizures refer to Type IA1 (simple partial seizures with motor signs), IB (complex partial seizures), and IC (partial seizures evolving to secondarily generalized seizures) of the International League Against Epilepsy (ILAE) Classification of Epileptic Seizures, 1981.

Study Arms (1)
UCB0942
EXPERIMENTALUCB0942 400 mg bid or a tapered UCB0942 dose of 200 mg bid. The Investigator will be allowed to increase or decrease the dose of UCB0942 to optimize tolerability and seizure control for each subject. Increases or decreases to the dose of UCB0942 should be made in steps not exceeding 200 mg/day per week; an exception is Taper Week 1 where a step of 800 mg/day to 500 mg/day is allowed. A faster decrease of the dose than 200 mg/day per week is allowed when it is clinically appropriate in the Investigator's medical judgment. Daily UCB0942 doses during this study may be 100 mg (50 mg bid), 200 mg (100 mg bid), 400 mg (200 mg bid), 600 mg (300 mg bid), or 800 mg (400 mg bid); intermediate doses will not be allowed except for tapering and titration unless agreed by the UCB Study Physician or PRA Medical Monitor. The dose of UCB0942 must always be administered as bid morning and evening doses, approximately 12 hours apart.
Interventions
* Active Substance: UCB0942 * Pharmaceutical form: Film-coated tablet * Concentration: 25 mg, 100 mg or 200 mg * Route of Administration: oral
Eligibility Criteria
You may qualify if:
- A written Informed Consent form approved by the Independent Ethics Committee is signed and dated by the subject, after the Investigator assesses whether the subject is able to understand the potential risks and benefits of participating in the study
- Subject must have completed Visit 13 (V13) of the Outpatient Maintenance Period of EP0069 to be eligible for enrollment into EP0073
- In EP0069, the subject demonstrated a reduction in frequency and/or severity of seizures as compared to baseline that is considered clinically significant by the Investigator and significant by the subject
- In EP0069, the subject experiences substantial benefit from UCB0942 with acceptable tolerability according to the subject and Investigator
- No tolerability issues that can outweigh attained benefits, in the opinion of the Investigator
- Female subjects of nonchildbearing potential (premenarcheal, postmenopausal for at least 2 years, bilateral oophorectomy or tubal ligation, and complete hysterectomy) are eligible. Female subjects of childbearing potential are eligible if they use medically accepted contraceptive methods
You may not qualify if:
- Subject has active suicidal ideation as indicated by a positive response ('Yes') to either Question 4 or Question 5 of the 'Since Last Visit' version of the Columbia Suicide Severity Rating Scale. The subject should be referred immediately to a Mental Healthcare Professional and must be withdrawn from the study
- Subject has taken other (non-Anti-Epileptic Drug) prescription, non-prescription, dietary (eg, grapefruit or passion fruit), or herbal products that are potent inducers or inhibitors of the CYP3A4 pathway for 2 weeks (or 5 half lives whichever is longer) prior to study entry
- Subject has an abnormality in the 12-lead electrocardiography that, in the opinion of the Investigator, increases the risks associated with participating in the study. In addition, any subject with any of the following findings will be excluded:
- Prolonged QTc (Bazett's, machine-read) interval defined as \> 450 ms for males and \> 470 ms for females
- Bundle branch blocks and other conduction abnormalities other than mild first degree atrioventricular block (defined as PR interval \>= 220 ms)
- Irregular rhythms other than sinus arrhythmia or occasional, rare supraventricular or rare ventricular ectopic beats
- In the judgment of the Investigator, T-wave configurations are not of sufficient quality for assessing QT interval duration
- Subject has a clinically significant abnormality on echocardiography at the Entry Visit (V2) of EP0073
- Upper limit of normal (ULN) of any of the following: alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), or \>ULN total bilirubin (\>=1.5xULN total bilirubin if known Gilbert's syndrome) at the EV (V2) of EP0073 (V15 of EP0069). If subject has elevations only in total bilirubin that are \>ULN and \<1.5xULN, fractionate bilirubin to identify possible undiagnosed Gilbert's syndrome (ie, direct bilirubin \<35%).
