Harmony Biosciences Acquires Asset With Novel Mechanism Of Action For The Potential Treatment Of Narcolepsy And Other Rare Neurological Diseases
"The acquisition of HBS-102 represents our first addition to the pipeline beyond WAKIX® (pitolisant), and our intention is to continue to pursue additional assets in line with our vision of becoming a leading rare neurological disease company with a robust portfolio of products," said
HBS-102 is a Melanin Concentrating Hormone Receptor 1 (MCHR1) antagonist that has the potential to offer a novel approach to the treatment of narcolepsy including the symptoms of
"Similar to WAKIX, this asset offers Harmony another opportunity to lead with the science and potentially bring another first-in-class treatment option to patients living with narcolepsy and other rare neurological diseases," said
Narcolepsy is a rare, chronic, debilitating neurological disease of sleep-wake state instability that impacts approximately 165,000 Americans and is primarily characterized by excessive daytime sleepiness (EDS) and cataplexy – its two cardinal symptoms – along with other manifestations of REM sleep dysregulation (hallucinations and sleep paralysis), which intrude into wakefulness. EDS is the inability to stay awake and alert during the day and is the symptom that is present in all people living with narcolepsy. In most patients, narcolepsy is caused by the loss of hypocretin/orexin, a neuropeptide in the brain that supports sleep-wake state stability. This disease affects men and women equally, with typical symptom onset in adolescence or young adulthood; however, it can take up to a decade to be properly diagnosed.

Important Safety Information
WAKIX is contraindicated in patients with known hypersensitivity to pitolisant or any component of the formulation and in patients with severe hepatic impairment. WAKIX is extensively metabolized by the liver and there is a significant increase in WAKIX exposure in patients with moderate impairment.
WAKIX prolongs the QT interval. Avoid use of WAKIX in patients with known QT prolongation or in combination with other drugs known to prolong the QT interval. Avoid use of WAKIX in patients with a history of cardiac arrhythmias, as well as other circumstances that may increase the risk of the occurrence of torsade de pointes or sudden death, including symptomatic bradycardia, hypokalemia or hypomagnesemia, and the presence of congenital prolongation of the QT interval.
The risk of QT prolongation may be greater in patients with hepatic or renal impairment due to higher concentrations of pitolisant; monitor these patients for increased QTc. Dosage modification is recommended in patients with moderate hepatic impairment and moderate or severe renal impairment. WAKIX is not recommended in patients with end-stage renal disease (ESRD).
In the placebo-controlled clinical trials conducted in patients with narcolepsy with or without cataplexy, the most common adverse reactions (≥5% and twice placebo) for WAKIX were insomnia (6%), nausea (6%), and anxiety (5%). Other adverse reactions that occurred at ≥2% and more frequently than in patients treated with placebo included headache, upper respiratory infection, musculoskeletal pain, heart rate increased, hallucinations, irritability, abdominal pain, sleep disturbance, decreased appetite, cataplexy, dry mouth, and rash.

HBS-102 is an investigational compound being developed as a potential treatment for narcolepsy and other rare neurological diseases. HBS-102 is a potential first-in-class molecule with a novel mechanism of action which targets melanin concentrating hormone (MCH) neurons in the hypothalamus, which make up the control center for REM sleep and related behaviors. In the setting of orexin deficiency (as occurs in patients with type 1 narcolepsy), there is an imbalance between orexin and MCH which could result in the control center for REM sleep going unchecked that could lead to REM sleep intruding into wakefulness. If that occurs, the clinical symptoms are experienced as cataplexy, hallucinations, and/or sleep paralysis. HBS-102, an MCHR1 antagonist, blocks the activity of the MCH neurons, which could potentially reduce REM intrusions into wakefulness and therefore reduce the debilitating symptoms of cataplexy, hallucinations and sleep paralysis.
