NBI-827104§
Rare Pediatric Epilepsy: EE-CSWS
EE-CSWS is a rare pediatric epilepsy syndrome characterized by onset of seizures with a unique electroencephalogram (EEG) pattern referred to as electrical status epilepticus in sleep (ESES). Cognitive stagnation and regression typically develop one to two years after onset. Following puberty, seizures tend to improve; however developmental delays often remain.
EE-CSWS impacts less than 2% of children living with epilepsy worldwide. There is no approved treatment for the disorder.
NBI-827104§ is an investigational, selective, orally active, and brain-penetrating T-type calcium channel blocker (Cav 3.1, Cav 3.2, Cav 3.3) currently under development for the potential treatment of EE-CSWS. Neurocrine Biosciences acquired the exclusive rights to NBI-827104§ from Idorsia.
We are conducting the STEAMBOAT Phase 2 study to evaluate NBI-827104§ in pediatric patients with EE-CSWS.

Congenital Adrenal Hyperplasia in Children & Adolescents
crinecerfont
Congenital Adrenal Hyperplasia in Adults
CAH is a rare genetic condition that results in an enzyme deficiency that alters the production of adrenal hormones that are essential for life. Approximately 95% of CAH cases are caused by a mutation that leads to deficiency of 21-hydroxylase (21-OHD). 21-OHD is an enzyme that is essential for making cortisol and aldosterone, two hormones that are critical to numerous physiologic functions. Cortisol allows the body to respond to injury, stress, or illness; and aldosterone maintains proper blood pressure and sodium levels. Severe deficiency of this enzyme can lead to an inability of the adrenal glands to produce cortisol and, in approximately 75% of cases, aldosterone. If left untreated, CAH can result in salt wasting, dehydration, and even death. This condition also results in overproduction of androgens, which can affect growth and sexual development and reduce fertility.
Glucocorticoids (GCs), the current standard of care, are used to correct the endogenous cortisol deficiency but doses used are higher than cortisol replacement needed (supraphysiologic) to lower levels of adrenocorticotropic hormone (ACTH) and androgens. However, glucocorticoid treatment at supraphysiologic doses has been associated with serious and significant complications of steroid excess, including metabolic issues, such as weight gain and diabetes, cardiovascular disease, and osteoporosis, and may also have psychological and cognitive impact, such as changes in mood and memory. On the other hand, androgen excess as a result of insufficient GC doses has been associated with abnormal bone growth and development in pediatric patients, female health problems such as acne, excess hair growth, and menstrual irregularities, testicular rest tumors in males and fertility issues in both sexes.
Crinecerfont is an investigational, oral, selective corticotropin-releasing factor type 1 (CRF1) receptor antagonist being studied to reduce and control excess adrenal androgens in people with CAH. Blocking CRF1 receptors in the pituitary gland has been shown to decrease ACTH levels, which in turn decreases the production of adrenal androgens and potentially the symptoms associated with classic CAH. Our data also suggests that lowering androgen levels enables lower, more physiologic dosing of GCs and thus could potentially reduce the complications associated with exposure to greater-than-normal GC doses in patients with classic CAH. Crinecerfont has been granted orphan drug designation in the US and European Union.
In September and October 2023, we announced top-line data from our CAHtalyst™ Pediatric and CAHtalyst™ Adult studies evaluating the efficacy, safety, and tolerability of crinecerfont in children, adolescents, and adults with CAH due to 21-OHD. The data from the CAHtalyst Pediatric and Adult studies, including data from the open-label treatment periods, supported regulatory submissions to the FDA in April 2024. The FDA granted Priority Review with Prescription Drug User Fee (PDUFA) target action dates in late December 2024.

Adrenal Insufficiency
Modified-release hydrocortisone
Adrenal insufficiency is a chronic endocrine condition that occurs when the body does not make enough of certain adrenal hormones, including cortisol and often aldosterone. Steroids such as hydrocortisone and glucocorticoids are used to replace the missing cortisol, but they cannot match the natural diurnal rhythm of the body’s cortisol production.
Modified-release hydrocortisone is an investigational therapy being developed to mimic the circadian rhythm of the body’s natural cortisol production as a potential treatment for adrenal insufficiency.
Congenital Adrenal Hyperplasia
Modified-release hydrocortisone
Classic CAH is a genetic disorder that causes little to no cortisol production and increased secretion of adrenocorticotropic hormone (ACTH) and androgens. In approximately 75% of cases, the adrenal glands cannot produce aldosterone, which can result in salt wasting adrenal crisis, causing extreme weakness, low blood pressure, shock, and even death. Steroids such as hydrocortisone and glucocorticoids are used to replace the missing cortisol, but they cannot match the natural diurnal rhythm of the body’s cortisol production.
Modified-release hydrocortisone is an investigational therapy being developed to mimic the circadian rhythm of the body’s natural cortisol production as a potential treatment for congenital adrenal hyperplasia.
Mental health disorders occur in more than 792 million people globally. New treatment options are critical to help lessen the personal, social, and economic toll on people who suffer from them.
Our pipeline includes early-to-mid-stage programs evaluating potential novel therapies for schizophrenia and major depressive disorder.
valbenazine*
Adjunctive Treatment of Schizophrenia
Schizophrenia is a serious and complex mental disorder that affects how a person thinks, feels, and behaves. As one of the leading causes of disability worldwide, it often results in significant emotional burden for those who experience symptoms, as well as their family and friends. Approximately 33% of the people living with schizophrenia fail to respond to current antipsychotic therapy.
Scientists believe that elevated dopamine in an area of the brain called the striatum is associated with symptoms of schizophrenia. Valbenazine* is an investigational, selective, orally active vesicular monoamine transporter 2 (VMAT2) inhibitor that is being investigated as a potential adjunctive treatment for patients with schizophrenia.
We are currently conducting the Journey™ Study, a Phase 3 study of valbenazine* as an adjunctive treatment in patients with schizophrenia.
