Many patients were on multiple medications, indicating a complex treatment landscape [43][46][55] 4. Recruitment Success: The company successfully dosed 61 patients in the trial, demonstrating that patient recruitment for focal epilepsy studies is feasible, contrary to common beliefs [31][32] 5. Background Therapy Impact: The drug's efficacy was observed even in patients already on sodium channel blockers, suggesting that it can provide additional benefits in a heavily medicated population [20][62] 6. Discontinuation Rates: 23% of patients discontinued the study, which is consistent with industry norms. The reasons for discontinuation were primarily patient choice rather than adverse events [78][90] 7.
