At the time of the interim analyses, patients received treatment for a mean duration of These data are exciting as they help us better understand the potential of TAKHZYRO to provide sustained prevention and reduce attack frequency long-term, across a range of patient demographics,' said Donatello Crocetta, M. A sustained reduction in attack rate was observed in this group, with numerically lower mean monthly attack rates of 0.

The median attack rate reduction was consistent across all subgroups, including patient sex, race, HAE type, age, BMI, history of prophylaxis use, history of laryngeal attacks, and baseline attack rate.

Lanadelumab is well-tolerated and effective across patient subgroups: findings from the HELP open-label extension study ; OAS 21 Recorded scientific content In this interim analysis, treatment with TAKHZYRO mg every two weeks was well-tolerated and effectively reduced attack rates over an extended treatment period across different patient demographic and disease characteristics.

According to the interim analysis, the median attack rate reduction was consistent regardless of patient sex All of the presentations are available throughout the duration of the digital congress via the online scientific programme. Non-rollover patients were treated with one mg dose every two weeks, beginning on Day 0. One hundred and ninety-three participants completed at least 12 months of treatment and 27 participants completed at least 24 months of treatment at the time of the interim analyses.

About Hereditary Angioedema Hereditary angioedema HAE is a rare genetic disorder that results in recurrent attacks of oedema - swelling - in various parts of the body, including the abdomen, face, feet, genitals, hands and throat.

The swelling can be debilitating and painful. It is often under-recognized, under-diagnosed and under-treated. Contraindication Hypersensitivity to the active substance or to any of the excipients.

Warnings and Precautions Traceability: In order to improve the traceability of biological medicinal products, the name and the batch number of the administered product should be clearly recorded. Hypersensitivity reactions have been observed. In case of a breakthrough HAE attack, individualized treatment should be initiated with an approved rescue medication. Interference with coagulation test: Lanadelumab can increase activated partial thromboplastin time aPTT due to an interaction of lanadelumab with the aPTT assay.

The reagents used in the aPTT laboratory test initiate intrinsic coagulation through the activation of plasma kallikrein in the contact system. Inhibition of plasma kallikrein by lanadelumab can increase aPTT in this assay. There were no differences in international normalised ratio INR between treatment groups. Sodium content: This medicinal product contains less than 1 mmol sodium 23 mg per vial, that is to say essentially 'sodium-free'.

Interactions No dedicated drug-drug interaction studies have been conducted. Based on the characteristics of lanadelumab, no pharmacokinetic interactions with co-administered medicinal products is expected. As expected, concomitant use of the rescue medication C1 esterase inhibitor results in an additive effect on lanadelumab-cHMWK response based on the mechanism of action MOA of call another sub vba and C1 esterase inhibitor.

Immunogenicity Treatment with lanadelumab has been associated with development of treatment emergent anti-drug antibodies ADA in All antibody titres were low. Adverse Reactions The most commonly observed adverse reaction The data in the poster show that the statistically significant improvements from baseline that were observed at week 12 were sustained in each subscale score of the Aberrant Behavior Checklist for Fragile X ABC-C FXS through two years for patients who participated in the open label extension.

These data were published in the August 2 ndonline edition of Journal of Neurodevelopmental Disorders. Press release. Zygel was added on to other medications being administered. At the completion of the week study Period 1patients could enter an extension study Period 2.

Thirteen patients who completed the Period 1 rolled into Period 2. One patient who withdrew during Period 2 for reasons unrelated to safety or efficacy had no efficacy data post week 12 and therefore was not included in the analyses.

Ten patients exceeded two years of therapy. Statistically significant improvements from baseline were observed at week 12 in all six subscale scores of the ABC-C FXS in Period 1 and these statistically significant improvements were sustained through two years in subjects who entered Period 2. The persistence of effect over the two-year period is as follows. In addition, statistically significant improvements from baseline were observed at week 12 in the total score and all five subscale scores of ADAMS and these statistically significant improvements persisted to two years.

At weekthe range of The boundaries of the polygon at screening and endpoint allow visualization of change across all domains cross-sectionally and over time. These radar charts suggest global and sustained reductions in severity with Zygel treatment in patients who entered Period 2.

Zygel was well tolerated in the FAB-C trial over two years. Treatment-emergent adverse events TEAEs — any event occurring during a trial period whether unrelated or related to study drug - are common in children and expected over a two-year period. No treatment-related TEAEs occurred in more than one patient. Only one serious adverse event constipation was reported over two years of treatment and was not related to treatment.

About Fragile X Syndrome FXS Fragile X syndrome is a rare genetic developmental disability that is the leading known cause of both inherited intellectual disability and autism spectrum disorder, affecting 1 in 3, to 4, males and 1 in 4, to 6, females. It is the most common inherited intellectual disability in males and a significant cause of intellectual disability in females, and the leading genetic cause of autism spectrum disorder ASD.

FXS is caused by a mutation in the Fragile X Mental Retardation gene FMR1 located on the X chromosome and leads to dysregulation of the endocannabinoid pathway including the reduction in endogenous cannabinoids 2-AG and anandamide. The disorder negatively affects synaptic function, plasticity and neuronal connections, and results in a spectrum of intellectual disabilities and behavioral symptoms, such as social avoidance and irritability.

I am excited that this recently approved and important new treatment option is now available for my patients. We thank GW and all our partners who invest in a better tomorrow for people with epilepsy. Patients aged years with a confirmed diagnosis of drug-resistant Dravet syndrome currently uncontrolled on one or more concomitant anti-epileptic drugs AEDs were eligible to participate in this Phase 3, randomized, double-blind placebo-controlled trial.

The average age of trial participants was nine years range The median baseline convulsive seizure frequency per month was 12 and the median baseline total seizure frequency per month was The primary endpoint of the study was the change in convulsive seizure frequency over the week treatment period 2-week titration followed by week maintenance at the target dose compared to baseline. The currently available safety data from this trial are consistent with the previous Phase 3 clinical trials.

Detailed findings from this clinical trial will be reported at a future medical conference and subsequently published in a medical journal. Dravet syndrome is a severe infantile-onset and highly treatment-resistant epileptic encephalopathy frequently associated with genetic mutations in the SCN1A sodium channels. Onset of Dravet syndrome occurs typically during the first year of life in previously healthy and developmentally normal infants.

Initial seizures are often body temperature related, severe, and long-lasting. Over time, patients with Dravet syndrome often develop multiple types of seizures, including tonic-clonic, myoclonic, and atypical absences and are prone to bouts of prolonged seizures including status epilepticus, which can be life threatening. Risk of premature death including SUDEP sudden unexpected death in epilepsy is elevated in patients with Dravet syndrome.

Additionally, the majority will develop moderate to severe intellectual and development disabilities and require lifelong supervision and care. GW is currently conducting an additional Phase 3 clinical trial in the treatment of seizures associated with TSC.

EPIDIOLEX cannabidiol oral solution is contraindicated in patients with a history of hypersensitivity to cannabidiol or any ingredients in the product. Concomitant use of valproate and elevated transaminase levels at baseline increase this risk. Transaminase and bilirubin levels should be obtained prior to starting treatment, at one, three, and six months after initiation of treatment, and periodically thereafter, or as clinically indicated.

Dose adjustment and slower dose titration is recommended in patients with moderate or severe hepatic impairment. EPIDIOLEX can cause somnolence and sedation that generally occurs early in treatment and may diminish over time; these effects occur more commonly in patients using clobazam and may be potentiated by other CNS depressants.

If these symptoms occur, consider if they are related to the AED or the underlying illness. Hematologic abnormalities were also observed.
