Freeline releases initial data for FLT180a

01 November 2018

Syncona Ltd, a leading healthcare company focused on investing in and building global leaders in life science, today announces that its portfolio company, Freeline, has released an abstract with initial data from the ongoing B-AMAZE Phase 1/2 clinical trial investigating a novel gene therapy, FLT180a for Haemophilia B.

Freeline is a leading, clinical stage AAV gene therapy company focused on liver expression for chronic systemic diseases. Syncona founded Freeline with Professor Amit Nathwani from University College London in 2015. FLT180a is a next generation gene therapy using a proprietary adeno-associated virus (AAV) capsid developed to better transduce human liver cells, and a codon optimised cassette. The trial is continuing.

The abstract notes that in the trial's first patient cohort:

· Two patients with severe Haemophilia B received FLT180a at a single dose of 4.5 x 1011 vector genomes/kg body weight, which was well-tolerated with no serious adverse events.

· Within four weeks of infusion, FIX activity[1] in both participants rose to more than 30% and has since stabilised at 46% and 48%, respectively.[2]

Initial results will be presented by the Chief Scientific Officer of Freeline, UCL Professor Amit Nathwani, at the 60th annual meeting of the American Society of Hematology (ASH) December 2018 in San Diego.

Syncona remains the sole institutional investor in Freeline alongside UCL Technology Fund. Syncona has an 80 per cent fully diluted stake in Freeline which is valued at cost and held at £63.5 million[3] following the first tranche of the Series B investment.
