~ Conference call for analysts to be held at 2:30pm BST / 9:30am ET (see details below)

Oxford, UK- 06 June 2018: Oxford BioMedica plc (LSE:OXB) ("Oxford BioMedica" or "the Group"), a leading gene and cell therapy group, today announces that it has entered into an exclusive worldwide licensing agreement with Axovant Sciences (NASDAQ: AXON) to develop and commercialise OXB-102, a gene therapy developed by Oxford BioMedica for Parkinson's disease utilising the LentiVector® platform.

Under the terms of the agreement, Oxford BioMedica will receive a $30 million upfront payment (approximately £22 million) including $5 million as pre-payment for manufacturing activities related to OXB-102, now renamed, AXO-Lenti-PD. Oxford BioMedica is also eligible to receive $55 million upon the achievement of specified development milestones and $757.5 million upon the achievement of specified regulatory and sales milestones, with 7% to 10% tiered royalties on net sales of AXO-Lenti-PD.

Axovant Sciences, a clinical-stage biopharmaceutical company dedicated to advancing treatments for patients with life-altering neurologic conditions and a member of the Roivant family of companies, will fund all clinical development costs and manufacturing process development and scale-up activities for AXO-Lenti-PD. The agreement also allows for both parties to put in place a clinical and commercial supply agreement for GMP manufacturing of AXO-Lenti-PD at Oxford BioMedica. Roivant remains committed to Axovant's success and are excited about the scientific potential of AXO-Lenti-PD. Axovant will be able to harness the full Roivant drug development platform to ensure its rapid development.

Axovant Sciences expects to initiate a Phase I/II dose escalation study of AXO-Lenti-PD in patients with advanced Parkinson's disease by the end of 2018.

John Dawson, Chief Executive Officer of Oxford BioMedica, said: "We are delighted to sign this significant agreement which not only underlines our LentiVector® enabled platform and product development strategy but further demonstrates Oxford BioMedica's ability to build multiple partnerships with leaders in their respective therapeutic fields. This agreement with Axovant also successfully demonstrates Oxford BioMedica's pre-stated strategy to externalise product development beyond the end of the pre-clinical phase.

"Axovant's expertise and focus on neurological disorders, which includes Parkinson's disease, makes them an ideal development and commercialisation partner for this programme. Coupled with strong support from parent company Roivant, we believe Axovant is perfectly positioned to bring AXO-Lenti-PD to the market as quickly as possible to treat patients with Parkinson's, a disease which still has a high unmet need."

Commenting on the deal, Pavan Cheruvu, Chief Executive Officer of Axovant Sciences, said: "Axovant, together with our parent company Roivant, remains committed to developing innovative treatments for serious degenerative conditions such as Parkinson's disease, and we are excited to partner with Oxford BioMedica, a recognised global leader in cell and gene therapy. OXB-102 is a potentially best-in-class gene therapy with the potential to transform Parkinson's disease treatment. This is an area of significant unmet medical need and a major market opportunity. Advancing this high-quality candidate is a key priority for the team at Axovant and we very much look forward to working with Oxford BioMedica."

About OXB-102 (AXO-Lenti-PD)

OXB-102, now known as AXO-Lenti-PD, is a lentiviral gene therapy with a clinically validated mechanism of action for the delivery of the three genes that encode the enzymes required for endogenous dopamine synthesis. Unlike current drug treatment, in which efficacy diminishes with long-term use, AXO-Lenti-PD is designed to provide patient benefit for multiple years following a single administration. AXO-Lenti-PD is a second-generation vector construct of OXB-101, also known as ProSavin®, with greater potency and increased transgenic expression observed in preclinical studies. Oxford BioMedica has successfully completed a Phase I/II study for OXB-101, which met its primary endpoint. The results, which were published in Lancet in 2014, demonstrate favourable safety and tolerability and a statistically significant improvement of motor function as measured by the UPDRS Part III score at 6 and 12 months following a one-time administration. This improvement was sustained in most patients for up to four years despite the progressively degenerative nature of Parkinson's disease.
