Otsuka receives positive CHMP opinion for LupkynisTM (voclosporin)
for the treatment of active lupus nephritis

LONDON, UK, 22 July 2022 - Otsuka Pharmaceutical Europe Ltd. today announces that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) has adopted a positive opinion relating to the use of LupkynisTM (voclosporin) in combination with mycophenolate mofetil for the treatment of adult patients with active class III, IV or V (including mixed class III/V and IV/V) lupus nephritis (LN).

Lupus nephritis is a serious complication of systemic lupus erythematosus (SLE), a chronic and debilitating autoimmune disease1,2. Up to 210 in 100,000 people in Europe live with SLE3 and, while more prevalent in women, men who develop SLE may experience a more severe disease4,5,6. Between 40 and 60 percent (depending on ancestry) of those with SLE are at risk of developing LN during their lifetime7,8, which has been suggested to cause irreversible nephron loss.9

"Lupus nephritis can have severe consequences if inadequately managed, which is why the positive recommendation received today is a significant milestone as we continue to work towards being able to offer this treatment option to patients," said Andy Hodge, CEO of Otsuka Pharmaceutical Europe Ltd. "We look forward to the outcome of the European Commission (EC) decision which, if positive, would make voclosporin the first oral medicine approved in the EU to treat active LN in adult patients".

The positive CHMP opinion is based on the results of the pivotal Phase 3 AURORA 1 study10 and the recent AURORA 2 continuation study11. The results of the AURORA 1 study demonstrated that voclosporin, in combination with mycophenolate mofetil (MMF) and low-dose corticosteroids, led to statistically superior complete renal response rates at 52 weeks compared to treatment with MMF and low-dose corticosteroids alone, with a generally comparable safety profile12. The AURORA 2 study demonstrated long-term safety and tolerability of voclosporin with a generally similar safety profile and no unexpected safety signals compared to placebo (both taken in combination with MMF and low-dose oral steroids) in patients receiving treatment for an additional 24 months following their completion in the AURORA 1 study.13

The positive opinion from the CHMP will now be reviewed by the EC, which has the authority to approve medicines for EU member states, as well as Iceland, Norway, Liechtenstein, and Northern Ireland. The EC has 67 days from the CHMP opinion to issue a final decision.

About LupkynisTM (voclosporin)

Voclosporin is an oral calcineurin inhibitor (CNI) for the treatment of LN secondary SLE. It has a postulated dual mechanism of action, acting as an immunosuppressant through inhibition of T-cell activation and cytokine production, and promoting podocyte stability in the kidney12.

About the collaboration between Otsuka Pharmaceutical Co. Ltd and Aurinia

In December 2020, Otsuka Pharmaceutical Co., Ltd. entered into a collaboration and licensing agreement with Aurinia for the development and commercialisation of voclosporin for the treatment of LN in the European Union, Japan, the United Kingdom, Russia, Switzerland, Norway, Belarus, Iceland, Liechtenstein, and Ukraine. In February 2022, Swiss Medic granted Otsuka orphan drug status for voclosporin in LN.

The US Food and Drug Administration approved voclosporin in combination with a background immunosuppressive therapy regimen, as the first FDA-approved oral medicine to treat adult patients with active LN in 2021.
