Takeda and TiGenix announce that Cx601 (darvadstrocel) has received a positive CHMP opinion to treat complex perianal fistulas in Crohn's disease

• First allogeneic stem cell therapy to receive positive CHMP opinion in Europe
• Cx601 offers potential new treatment option for patients who do not respond to current available therapies and are subject to numerous invasive surgeries^[1]

Osaka, Japan, December 15, 2017 and Leuven, Belgium, December 15, 2017, 13:10h CET - Takeda Pharmaceutical Company Limited (TSE: 4502) ("Takeda") and TiGenix NV (Euronext Brussels and NASDAQ: TIG) ("TiGenix") today announced that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA), in conjunction with the Committee for Advanced Therapies (CAT), has adopted a positive opinion recommending a marketing authorization (MA) for investigational compound Cx601 (darvadstrocel). Cx601 is expected to be indicated for the treatment of complex perianal fistulas in adult patients with non-active/mildly active luminal Crohn's disease, when fistulas have shown an inadequate response to at least one conventional or biologic therapy.^[2] This recommendation marks the first allogeneic stem cell therapy to receive a positive CHMP opinion in Europe.

"Following today's news, physicians and surgeons in Europe can look forward to offering these Crohn's disease patients a novel and minimally invasive alternative treatment option in the future, which in clinical trials achieved higher combined remission and lower relapse rates^[*] than the current standard of care," said Professor Julian Panés, Head of the Gastroenterology Department at the Hospital Clinic of Barcelona (Spain) and President of the European Crohn's and Colitis Organisation (ECCO). "Perianal fistulas are estimated to affect up to 28% of patients in the first two decades after Crohn's disease diagnosis and Cx601 offers new hope for those suffering from this severe and debilitating condition."

Cx601 was assessed by the CAT, the EMA's specialized scientific committee for Advanced Therapy Medicinal Products (ATMP), such as gene or cell therapies. The positive CHMP opinion was based on results from TiGenix's Phase III ADMIRE-CD pivotal trial. The ADMIRE-CD trial is a randomized, double-blind, controlled, Phase III trial designed to investigate the efficacy and safety of investigational compound Cx601.^[3] 24-week results were published in The Lancet and showed that Cx601 achieved statistically significant superiority versus the control group in the primary efficacy endpoint of combined remission.^[],1 In addition, the rates and types of treatment related adverse events (non-serious and serious) and number of discontinuations due to adverse events were comparable between Cx601 and control arms, the most common of which were anal abscess and proctalgia.¹ Further follow-up data indicated that Cx601 maintained long-term remission of treatment refractory complex perianal fistulas in patients with Crohn's disease over 52 weeks.^[4]

Dr. María Pascual, VP Regulatory Affairs and Corporate Quality at TiGenix, said, "We believe that this first approval recommendation for an allogeneic stem cell therapy in Europe reflects the maturity of our technology and its potential to offer new approaches for difficult to treat conditions. We have worked closely with the EMA and provided a robust data package from a well-designed clinical trial with challenging endpoints. In parallel, we will continue working hard to obtain regulatory approval in the U.S. and to develop Cx601 for additional indications, to fulfil our aim of allowing patients to benefit from the full potential of Cx601 across multiple geographies and diseases."

The opinion will now be referred to the European Commission with a decision anticipated in the coming months. An MA will allow Cx601 to be marketed in all 28 member states of the EU, plus Norway, Iceland and Lichtenstein.

Cx601 has been licensed to Takeda for the exclusive development and commercialization outside of the U.S. Receipt of the MA will trigger a milestone payment from Takeda to TiGenix of €15 million. The companies have been working closely together to advance preparations for commercialization, with a potential start of the commercial launch by Takeda anticipated after MA is transferred from TiGenix to Takeda.

"Today's positive CHMP opinion is a crucial step to bringing a new treatment option to patients with complex perianal fistulas in Crohn's disease," said Dr. Asit Parikh, Head of Takeda's Gastroenterology Therapeutic Area Unit. "We would like to thank the scientific community and patients involved in the ADMIRE-CD trial for their support in helping us reach this important milestone. We remain committed to delivering innovative, therapeutic options for patients suffering from gastrointestinal disorders."   

Complex perianal fistulas are considered one of the most disabling complications of Crohn's disease^[5] and can cause intense pain^[6] and swelling, infection and incontinence.¹ Despite available therapies and surgical advancements, they currently remain challenging for clinicians to treat^[7] and have a significant negative impact on patient quality of life.⁶

About Cx601

Cx601 is a local administration of allogeneic (or donor derived) expanded adipose-derived stem cells (eASCs) for the treatment of complex perianal fistulas in adult Crohn's disease patients that have previously shown an inadequate response to at least one conventional therapy or biologic therapy. Crohn's disease is a chronic inflammatory disease of the intestine and complex perianal fistulas are a severe and debilitating complication for which there is currently no effective treatment. Cx601 was granted orphan drug designation by the European Commission in 2009 and by the U.S Food and Drug Administration (FDA) in 2017. TiGenix completed a European Phase III clinical trial (ADMIRE-CD) in August 2015 in which both the primary endpoint and the safety and efficacy profile were met, with patients receiving Cx601 showing a 44% greater probability of achieving combined remission compared to control (placebo).¹ A follow-up analysis was completed at 52 weeks⁴ and 104 weeks post-treatment, confirming the sustained efficacy and safety profile of the product. The 24-week results of the Phase III ADMIRE-CD trial were published in The Lancet  in July 2016.¹ Based on the positive 24 weeks Phase III study results, TiGenix submitted a Marketing Authorization Application to the European Medicines Agency (EMA). A global Phase III clinical trial (ADMIRE-CD II) intended to support a future U.S. Biologic License Application (BLA) started in 2017, based on a trial protocol that has been agreed with the FDA through a special protocol assessment procedure (SPA) (clinicaltrials.gov; NCT03279081). ADMIRE-CD II is a randomized, double-blind, placebo-controlled study designed to confirm the efficacy and safety of a single administration of Cx601 for the treatment of complex perianal fistulas in Crohn's disease patients. In July 2016, TiGenix entered into a licensing agreement with Takeda, a global pharmaceutical company active in gastroenterology, under which Takeda acquired exclusive rights to develop and commercialize Cx601 for complex perianal fistulas in Crohn's patients outside of the U.S.
