Chugai Pharmaceutical Co., Ltd. (TOKYO: 4519) announced that the U.S. Food and Drug Administration (FDA) has approved the pH-dependent binding humanized anti-IL-6 receptor monoclonal antibody, Enspryng™ (US generic name: satralizumab-mwge) (hereafter, Enspryng) created by Chugai for the treatment of adults living with anti-aquaporin-4 (AQP4) antibody positive neuromyelitis optica spectrum disorder (NMOSD). Enspryng is administered subcutaneously every four weeks**. Enspryng was granted Breakthrough Therapy Designation in December 2018 and the US Biologics License Application (BLA) was filed in August 2019 by Genentech Inc., a member of Roche Group.

This approval is based on the results from two global phase III clinical studies in patients with NMOSD: SAkuraSky Study (NCT02028884) and SAkuraStar Study (NCT02073279). SAkuraSky is a study to evaluate Enspryng in combination with baseline immunosuppressive treatment, and SAkuraStar is a study to evaluate Enspryng as monotherapy.

Enspryng, created by Chugai, is a pH-dependent binding humanized anti-IL-6 receptor antibody, which was the first product developed by applying our proprietary recycling antibody technology. The drug is believed to prevent relapse of NMOSD by inhibiting IL-6 signal signaling which is a key driver in NMOSD. Enspryng has been approved in Canada, Japan and Switzerland. Enspryng is designated as an orphan drug in Europe. The application was accepted for review by the European Medicines Agency in 2019.

*Self-administration is not included in Japanese package insert
**Subcutaneous administration at 2-week intervals up to the fourth week of treatment and at 4-week intervals thereafter

About neuromyelitis optica spectrum disorder (NMOSD)

NMOSD is an autoimmune disease of the central nervous system characterized by inflammatory lesions in the optic nerves and spinal cord, and cause continual and significant decrease in quality of life due to permanent neurological disability. Patients with NMOSD frequently experience a relapsing disease course with repeated attacks leading to accumulating neurological damage and disability. Symptoms may include visual impairment, motor disability, pain leading to decreased quality of life. In some cases, attacks of NMOSD result in death. Aquaporin-4 antibodies (AQP4-IgG), pathogenic antibodies, are detected in at least two-thirds of NMOSD people. AQP4-IgG is known to target and damage a specific central nervous cell type called astrocytes, resulting in inflammatory demyelinating lesions of the optic nerve(s), spinal cord and brain 1-4. The inflammatory cytokine IL-6 is now emerging as an important factor in NMOSD pathogenesis 5-9.

Diagnostic criteria introduced in 2006 for NMO were characterized by inflammation of the optic nerve (optic neuritis) and the spinal cord (myelitis). These were revised in 2007 with the definition of NMOSD, proposed for diseases with either optic neuritis or myelitis. In 2015, the definition of NMOSD further revised to include a broader spectrum of diseases. The diagnostic term NMOSD is now widely used 10.

Corcept Announces CHMP Opinion Recommending EU Marketing Authorization for Lifyorli ® (Relacorilant)18.9.2026 15:00:00 EEST | Press release

Corcept Therapeutics Incorporated (NASDAQ: CORT), a commercial-stage company engaged in the discovery and development of medications to treat severe endocrinologic, oncologic, metabolic and neurologic disorders by modulating the effects of the hormone cortisol, today announced that the European Medicines Agency’s Committee for Medicinal Products for Human Use (CHMP) has recommended that the European Commission (EC) should approve relacorilant, combined with the chemotherapy drug nab-paclitaxel, for the treatment of patients with platinum-resistant ovarian cancer. The CHMP’s recommendation is based on positive data from Corcept’s Phase 2 and pivotal Phase 3 ROSELLA trials, in which patients receiving relacorilant combined with nab-paclitaxel experienced improved progression-free and overall survival compared to patients who received nab-paclitaxel alone. The safety profile of relacorilant plus nab-paclitaxel in these trials was consistent with the safety profile of nab-paclitaxel monoth

Enhertu® (trastuzumab deruxtecan) has been recommended for approval in the European Union (EU) as a monotherapy for the adjuvant treatment of adult patients with resected HER2 positive breast cancer who have residual invasive disease after neoadjuvant taxane-based and HER2 targeted treatment. Enhertu is a specifically engineered HER2 directed DXd antibody drug conjugate (ADC) discovered by Daiichi Sankyo (TSE: 4568) and being jointly developed and commercialized by Daiichi Sankyo and AstraZeneca (LSE/STO/NYSE: AZN). The Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) based its positive opinion on results from the DESTINY-Breast05 phase 3 trial presented at the 2025 European Society for Medical Oncology (#ESMO25) Congress and subsequently published in The New England Journal of Medicine. The recommendation will now be reviewed by the European Commission, which has the authority to grant marketing authorizations for medicines in the EU. In DES
