Previous preclinical studies^3,4 have already shown that the choice of epit= ope is an important efficacy determinant for therapeutic anti-Tau antibodie= s. This first in human, randomised, subject blind, investigator blind, plac= ebo-controlled, single-ascending-dose study has been selected as a late bre= aking highlight by the MDS congress organisers, reflecting the importance o= f these data.=C2=A0 The aim of the research was to evaluate the safety, tolerability and pharma= cokinetics of UCB0107 in healthy volunteers. =C2=A0=E2=80=9CWe=E2=80=99re learning more and more about the role of Tau d= eposits and the extent to which they are closely linked to symptoms of neur= odegeneration such as movement disorders, memory loss and dementia=E2=80=9D= explained Colin Ewen, UCB Development Lead, UCB0107. =E2=80=9CDevelopment = of a medicine with a positive safety and tolerability profile, which could = tackle the build-up of Tau, would offer hope to many millions of people imp= acted by neurodegenerative diseases=E2=80=9D. The primary endpoint used in the study was incidence of adverse events. Dat= a relating to other safety assessments (neurological examination, MRI, ECG,= clinical chemistry, haematology, coagulation, urinalysis and vital signs) = were also collected. Additional secondary endpoints measured serum and cere= brospinal (CSF) PK parameters.=C2=A0 52 healthy male adults were randomized and assigned to one of seven dose co= horts to receive UCB0107 or placebo by iv infusion. All participants comple= ted the study.=C2=A0 Over the course of the study, the most common treatment-emergent adverse ev= ent (TEAE) in the total UCB0107 and placebo groups was headache (15.8% and = 35.7%, respectively). One severe TEAE of leg varicose ulceration was report= ed in one participant with a history of varicose veins and varicose-vein st= ripping. No serious or drug-related TEAEs were reported. There were no clin= ically relevant changes in other safety results.=C2=A0 =E2=80=9CThe UCB development process combines insights from patients and ca= regivers, collaborations with leading experts from around the world, and cu= tting-edge scientific methods to address important unmet medical challenges= . This approach provides a uniquely holistic view about the unmet needs fac= ing patients and the potential for an effective anti-Tau antibody in the tr= eatment of neurodegenerative diseases=E2=80=9D, explained Charl van Zyl, He= ad of Neurology Patient Value Unit & Executive Vice President, UCB. =E2=80= =9CThese first in human safety and tolerability results support our belief = in the potential for UCB0107 to provide value for people living with neurod= egenerative disorders who currently have very limited or no treatment optio= ns. They validate our decision to continue the clinical development of this= new asset.=E2=80=9D Results from this study, combined with results from pre-clinical research^3= ,4 support progression of UCB0107 clinical development in patients with tau= opathies such as PSP.=C2=A0 Preparations are underway to initiate an adequate and well controlled study= in Q2 2020. About UCB0107 UCB0107 is a recombinant, humanised, full-length IgG4 monoclonal antibody, = targeting a central Tau epitope, which is being developed to block/reduce t= he spread of Tau pathology.
