A method of increasing an average time between seizures in a human patient diagnosed with Dravet syndrome, comprising administering to the patient a therapeutically effective dose of fenfluramine or a pharmaceutically acceptable salt, base, acid or amine thereof, and repeating the administering over a period of days until the patient exhibits an increase from baseline in average time between convulsive seizures of 6 hours, days weeks or more.

Disclosed herein are methods of improving cognitive function in a patient as measured by, for example, improvement in score on a validated scale that measures cognitive function, such as the Behavior Rating Inventory of Executive Function (BRIEF), by administering the test to a patient and obtaining a pre-treatment test score, treating the patient with fenfluramine or its pharmaceutically acceptable salt, and after treatment, re-administering the test of cognitive function to the patient and obtaining a post-treatment score, to allow observation of an improvement in the test score. In some embodiments, the patient is also being treated for the symptoms of epilepsy.

Provided herein is a method of treating a selected patient population, wherein the patient population is selected based on a determination that the patients have previously been non-responsive when treated with cannabidiol. In some embodiments, the method comprises selecting the patient based on a previously failed treatment with cannabidiol, based on lack of efficacy or tolerability. Pharmaceutical compositions and formulations for use in practicing the subject methods are also provided. The method comprises identifying a population of patients diagnosed with Dravet syndrome who were found previously to have been non-responsive when treated with cannabidiol. The selected population of patients is then treated by administering, to each identified patient, a therapeutically effective dose of fenfluramine or a pharmaceutically acceptable salt, base, acid or amine thereof, and repeating the administering over a period of a day or days, or over a period of weeks, months or years, until the patient exhibits a reduction from baseline in convulsive seizure frequency.

A method of reducing convulsive seizure frequency in a human patient diagnosed with Dravet syndrome, comprising administering to the patient a therapeutically effective dose of fenfluramine or a pharmaceutically acceptable salt, base, acid or amine thereof, and repeating the administering over a period of days until the patient exhibits a significant reduction (e.g., 40% or greater) from baseline in convulsive seizure frequency. In some embodiments of the method, convulsive seizures are completely eliminated for 10 days or more, 20 days or more, 30 days or more, 50 days or more, 100 days or more.

Functional analogs of fenfluramine are provided. The subject fenfluramine functional analogs find use in the treatment of a variety of diseases. For example, methods of treating epilepsy by administering a fenfluramine analog to a subject in need thereof are provided. Also provided are methods of treating a neurodegenerative disease in a subject in need thereof. Pharmaceutical compositions for use in practicing the subject methods are also provided.

A method of treating and / or preventing symptoms of Doose syndrome in a patient such as a patient previously diagnosed with Doose syndrome, by administering an effective dose of fenfluramine or its pharmaceutically acceptable salt to that patient. Doose syndrome patients are treated at a preferred dose of less than about 10.0 to about 0.01 mg / kg / day.

The present invention relates to the use of cannabidiol (CBD) in combination with an agonist of 5-HT2B receptors. Such a combination provides protection against the adverse effects caused by agonists of 5-HT2B receptors. The invention further relates to the use of CBD in combination5 with an amphetamine or amphetamine derivative in the treatment of epilepsy. In one embodiment the CBD is used in combination with the amphetamine derivative fenfluramine to produce a significant reduction in seizures. Preferably the CBD used is in the form of a highly purified extract of cannabis such that the CBD is present at greater than 98% of the total extract (w / w) and the other components of the extract are characterised. In particular the cannabinoid10 tetrahydrocannabinol (THC) has been substantially removed, to a level of not more than 0.15% (w / w) and the propyl analogue of CBD, cannabidivarin, (CBDV) is present in amounts of up to 1%. Alternatively, the CBD may be a synthetically produced CBD. In use the CBD in combination with an agonist of 5-HT2B receptors, amphetamine or amphetamine derivative may be formulated for administration separately, sequentially or simultaneously with the15 amphetamine or amphetamine derivative or the combination may be provided in a single dosage form. Where the CBD is formulated for administration separately, sequentially or simultaneously it may be provided as a kit or together with instructions to administer the one or more components in the manner indicated.
