News update



February 2024: Presentation of preliminary results of IBIS study at Late-Breaking Sciences - International Stroke Conference 2024, Phoenix Arizona. Title Poster: Safety, pharmacokinetics and preliminary efficacy of the neuroprotectant 2-iminobiotin in patients with Ischemic Stroke treated with mechanical thrombectomy.


September 2023: Enrollment of patients completed in IBIS study (phase II double blind randomised placebo controlled trial) in acute ischemic stroke.

September 2023: Neurophyxia is invited as panellist and participates at the Conect4Children Multi-Stakeholder Meeting on Perinatal Asphyxia, Rome. 

September 2023: Neurophyxia announces the publication of the article entitled “2-iminobiotin, a selective inhibitor of nitric oxide synthase, improves memory and learning in a rat model after four vessel occlusion, mimicking cardiac arrest”.  The results of the study, published in PLOS ONE (see link), demonstrate that 2-Iminobiotin, administered directly upon reperfusion, significantly improves long term memory and learning in a 4VO rat model model of global ischemia. On top of the results of Neurophyxia’s lead compound 2-Iminobiotin in Phase IIa clinical trials, showing excellent safety and tolerability and predictive PK in adults after cardiac arrest and neonates with perinatal asphyxia, this study underscores the unique potential of 2-Iminobiotin as a neuroprotectant in cerebral hypoxia ischemia and reperfusion injury.

June 2023: The results of the phase IIa TIBOHCA study, investigating safety, tolerability and pharmacokinetics of 2-iminobiotin after cardiac arrest in adults, have been published in Frontiers in Neurology (see link). The study shows that 2-iminobiotin has an excellent safety profile with predictable PK after correction for renal function on admission. Promising – though preliminary-  neuronal biomarker, mortality and CPC data have been obtained, for reference (see link). Based on the results of the TIBOHCA study, the optimal dose for next phases of clinical development was identified.

May 2023: recruitment of IBIS trial in acute ischemic stroke half way without any safety concerns.

February 2023:  Neurophyxia successfully passed the GMP inspection by the Health and Youth Care Inspectorate (Inspectie Gezondheidszorg en Jeugd, IGJ) on February 2nd 2023. The IGJ inspection confirmed Neurophyxia to be compliant with the principles and guidelines of Good Manufacturing Practices (GMP) and no major or critical observations were issued. As a result from this successful inspection, a GMP Certificate has been issued extending Neurophyxia’s GMP status.
