Centessa Pharmaceuticals Plc Stock Price, News & Analysis

Centessa Pharmaceuticals plc (Nasdaq: CNTA) is a clinical-stage pharmaceutical company that aims to discover, develop and ultimately deliver medicines that are transformational for patients. According to the company’s disclosures, Centessa is focused on developing a new class of potential therapies built around its orexin receptor 2 (OX2R) agonist program, targeting symptoms such as excessive daytime sleepiness (EDS), impaired attention, cognitive deficits and fatigue across neurological, neurodegenerative and neuropsychiatric disorders.

Core focus: orexin receptor 2 (OX2R) agonist pipeline

Centessa describes orexin as a neuropeptide that regulates the sleep–wake cycle, leading to arousal and promoting wakefulness. The company is developing a pipeline of OX2R agonist drug candidates designed to modulate this pathway. Its program includes:

• ORX750 for the treatment of sleep–wake disorders, including narcolepsy type 1 (NT1), narcolepsy type 2 (NT2) and idiopathic hypersomnia (IH). ORX750 is being evaluated in the Phase 2a CRYSTAL‑1 study in central disorders of hypersomnolence.
• ORX142, a novel, highly potent and selective OX2R agonist being developed for select neurological and neurodegenerative disorders and evaluated in a first‑in‑human Phase 1 clinical study in healthy volunteers.
• ORX489, an OX2R agonist drug candidate in IND‑enabling studies for neuropsychiatric disorders.

Centessa states that ORX750, ORX142 and ORX489 are investigational candidates that have not been approved by the U.S. Food and Drug Administration (FDA) or any other regulatory authority.

Therapeutic areas and indications

Based on company communications, Centessa’s OX2R agonist pipeline is being developed to address:

• Central disorders of hypersomnolence, including NT1, NT2 and IH, through ORX750.
• Select neurological and neurodegenerative disorders through ORX142.
• Neuropsychiatric disorders through ORX489.

The company highlights that targeting the orexin pathway with novel OX2R agonists may offer a way to address EDS, impaired attention, cognitive deficits and fatigue associated with a broad range of neurological, neurodegenerative and neuropsychiatric conditions.

Clinical development activities

Centessa reports that the CRYSTAL‑1 Phase 2a study of ORX750 is an adaptive, randomized, double‑blind, placebo‑controlled trial in central disorders of hypersomnolence. The study is designed to evaluate safety, tolerability, pharmacokinetics and pharmacodynamic measures, and to identify optimal doses for future registrational development in NT1, NT2 and IH. The company has disclosed Phase 2a data from initial dosing cohorts in these indications, including assessments using the Maintenance of Wakefulness Test (MWT), Epworth Sleepiness Scale (ESS) and Weekly Cataplexy Rate (WCR) in NT1.

For ORX142, Centessa describes an ongoing first‑in‑human Phase 1 study in healthy adult participants, including single‑ascending and multiple‑ascending dose cohorts, as well as a placebo‑controlled crossover pharmacodynamic assessment in acutely sleep‑deprived volunteers using the MWT and Karolinska Sleepiness Scale (KSS). The company has reported Phase 1 data indicating a rapid onset of action, differentiated pharmacokinetics and pharmacodynamic effects in sleep‑deprived volunteers.

ORX489 is described as the company’s most potent OX2R agonist candidate to date, advancing through IND‑enabling studies with planned clinical evaluation following regulatory clearance.
