Kaerus Bioscience's lead candidate KER-0193 granted Orphan Drug Designation and Rare Pediatric Drug Designation by U.S. FDA for treatment of Fragile X syndrome (FXS)
FDA's two designations demonstrate KER-0193's potential as a treatment for FXS Follows the successful completion of Phase 1 clinical trial Fragile X syndrome is the most common cause of inherited autism LONDON, May 14, 2025 /PRNewswire/ -- Kaerus Bioscience ("Kaerus" or "the Company"), a clinical stage biopharmaceutical company created by Medicxi for the development of therapeutics for rare genetic syndromes of neurodevelopment, today announces that its lead candidate KER-0193 has been granted both Orphan Drug Designation and Rare Pediatric Drug Designations for the treatment of Fragile X syndrome (FXS) by the U.S. Food and Drugs Administration (FDA). It follows the recent successful completion of a Phase 1 trial of KER-0193 in healthy volunteers, which confirmed the drug to be safe, well tolerated and exhibit excellent pharmacokinetics. FXS is an inherited condition, affecting about 1 in 7,000 males and 1 in 11,000 females, for which there are currently no approved treatments. It is the most common cause of inherited autism and intellectual disability, accounting for approximately 1 per cent of such cases globally. Dr Robert Ring, CEO of Kaerus Bioscience, said: "The FDA's granting of Orphan Drug Designation and Rare Pediatric Drug Designation for KER-0193 is an important step towards our objective of delivering an effective treatment for people with Fragile X syndrome. "Not only do these two FDA designations affirm the therapeutic potential of KER-0193 in Fragile X syndrome, they also provide Kaerus with access to significant regulatory and financial incentives as we look to progress the drug through clinical trials and ultimately take it to market." Paul Sekhri, Chairman of Kaerus Bioscience, said: "These important FDA designations are more excellent news for Kaerus, coming after the impressive Phase 1 results showing KER-0193 to be safe and well-tolerated. These developments put the Company in a superb position as we look to move into Phase 2 trials." Both FDA programmes are aimed at encouraging the development of treatments for rare diseases. Discovered by Kaerus, KER-0193 is a novel, orally-bioavailable small molecule designed to specifically address hyper-excitability of brain function commonly associated with Fragile X syndrome. KER-0193 does this by targeting BK channels (calcium-activated potassium channels), which have been described as master regulators of excitability across the nervous system. The genetic cause of FXS is directly linked to a reduction in BK channel function. Based on its broad efficacy profile in preclinical genetic models of FXS, Kaerus is excited by the therapeutic potential of KER-0193 to address the diversity of behavioural, sensory and cognitive challenges that adversely impact the lives of individuals with FXS. Kaerus's conviction has been strengthened by a pre-planned sub-study, conducted during the Phase 1 trial, in which the effects of KER-0193 on brain activity in healthy volunteers were investigated using electroencephalography (EEG). The study convincingly demonstrated that KER-0193 enters the brain and produces pharmcodynamic effects on brain activity in regions often implicated in patients with FXS. These results replicated observations from EEG profiling of KER-0193 in preclinical animal studies, demonstrating proof of mechanism. Beyond FXS, reduced BK channel activity has been implicated in a number of other neurological conditions, including epilepsy and several rare genetic epileptic encephalopathies. Dr Ring said: "We are actively exploring opportunities to expand the therapeutic potential of our BK modulator platform to these other indications, where patient populations struggle with significant unmet treatment needs." The company is finalising preparations for a Phase 2 proof-of-concept study in FXS patients.

Kaerus Bioscience Successfully Completes Phase 1 Trial and Demonstrates Proof of Mechanism with its Novel BK Channel Modulator KER-0193 being developed for Fragile X Syndrome
LONDON, March 11, 2025 (GLOBE NEWSWIRE) -- Kaerus Bioscience ( a clinical-stage biopharmaceutical company created by Medicxi for the development of therapeutics for rare genetic syndromes of neurodevelopment, today announces the successful completion of its Phase 1 clinical trial of KER-0193, a novel BK channel modulator the company is developing for Fragile X syndrome (FXS) and other neurodevelopmental conditions. In the trial, KER-0193 was found to be safe and well-tolerated in both single ascending dose and multiple ascending dose cohorts involving 56 healthy volunteers. The drug also exhibited an excellent, dose-proportional pharmacokinetic profile across a wide range of doses. A planned biomarker substudy profiling brain activity using electroencephalography (EEG) was also completed as part of the Phase 1 clinical trial. The results of this pharmaco-EEG study revealed significant pharmacodynamic effects of KER-0193 on multiple, translationally-relevant parameters of brain activity, providing clear clinical evidence of central target engagement for KER-0193. Pharmaco-EEG also revealed a unique topography of KER-0193 effects on brain excitability that specifically maps to cortical regions commonly reported as abnormal by EEG in patients with FXS. This pattern of regional effects on brain excitability replicates observations from EEG profiling of KER-0193 in preclinical animal studies, demonstrating proof of mechanism. 'These results are a significant milestone for Kaerus,' said Dr. Robert Ring, CEO, Kaerus Bioscience. 'The data clearly demonstrate our first-in-class BK channel modulator is active in the CNS, and is both safe and well-tolerated. Taken together with the positive 'proof of mechanism' with EEG, we feel extremely excited and confident heading into Phase 2 in the target population.' The company is currently finalizing preparations for a Phase 2 proof of concept study in FXS patients.
