The European Commission Grants Orphan Drug Designation to NS-229 for the Treatment of Eosinophilic Granulomatosis with Polyangiitis
PARAMUS, NJ: January 22, 2024 – NS Pharma, Inc. (NS Pharma), a subsidiary of Nippon Shinyaku Co., Ltd, announced today that the European Commission (EC) has granted orphan drug designation to NS-229, which is being developed for the treatment of the rare disease eosinophilic granulomatosis with polyangiitis (EGPA).
The orphan drug designation by the EC is issued for drugs which are intended to treat diseases that affect fewer than five in 10,000 people in the European Union and are life- threatening or chronically debilitating. The Orphan Drug Designation provides NS Pharma with a ten-year marketing exclusivity period, supporting the company’s continued development and evaluation of this therapy.
EGPA is an autoimmune disease that is generally preceded by symptoms of bronchial asthma and allergic rhinitis. This inflammation in the small blood vessels can cause tissue and organ damage to the lungs, sinuses, peripheral nerves, skin, and kidneys. The cause of EGPA is unknown.
“EGPA is a serious, life-threatening disease with unmet medical need,” explained NS Pharma Vice President, Research & Development, Takeshi Seita. “We are encouraged that our innovative therapy will proceed in development for the patients who need
treatment.”
NS-229 is a potent and selective Janus kinase (JAK) 1 inhibitor, developed in-house, which suppresses excessive activation of T cells, B cells and certain white blood cells. As a result, it is anticipated that NS-229 could reduce tissue damage and curb various symptoms of EGPA. A Phase II global study of NS-229 is scheduled to be conducted by NS Pharma.

NS-089/NCNP-02 Receives Orphan Drug Designation from the European Commission for the Treatment of Duchenne Muscular Dystrophy
PARAMUS, NJ: December 21, 2023 – NS Pharma, Inc. (NS Pharma), a subsidiary of Nippon Shinyaku Co., Ltd., announced that, on December 13, 2023, the European Commission (EC) has granted orphan drug designation for NS-089/NCNP-02, which is being developed for the treatment of Duchenne muscular dystrophy (Duchenne), a rare and deadly genetic disorder that occurs primarily in males. There are various genetic mutations that cause Duchenne, and NS-089/NCNP-02 targets a gene mutation that can be treated by exon 44 skipping.
The orphan drug designation by the EC is issued to drugs which are intended for diseases that affect fewer than five in 10,000 people in the European Union (EU) and are life- threatening or chronically debilitating. The designation provides NS Pharma with a ten- year marketing exclusivity period, supporting the company’s continued development and evaluation of this therapy.
NS-089/NCNP-2 was previously granted rare pediatric disease designation in June 2023, designated as a breakthrough therapy in July 2023, and designated as an orphan drug in July 2023 by the U.S. Food and Drug Administration (FDA).
“We are one step closer to helping patients with Duchenne who are amenable to exon 44 skipping access life-changing treatment,” said NS Pharma Vice President, Research & Development, Takeshi Seita. “Our team is ready and excited to continue our development of this innovative science.”
NS-089/NCNP-02 is an antisense nucleic acid discovered through joint research between Nippon Shinyaku and the National Center of Neurology and Psychiatry (NCNP). It skips part of the genetic information of the dystrophin gene and produces a functional dystrophin protein with a slightly shorter chain length, which is expected to have the effect of suppressing muscle function deterioration.
NS Pharma has been actively working to develop agents for the treatment of intractable and rare diseases, with a goal of launching treatments for patients with Duchenne as soon as possible.

NS Pharma Unveils Duchenne Heroes, a Program to Inspire and Amplify the Voices of People Living with Duchenne Muscular Dystrophy
Paramus, NJ: November 21, 2023 – NS Pharma, Inc. (“NS Pharma”) today announced the launch of Duchenne Heroes a program created to raise awareness and champion the voices of people affected by Duchenne muscular dystrophy (Duchenne). Duchenne Heroes are individuals, caregivers and family members who hope to inspire others by sharing their personal experiences in navigating diagnosis and daily life with Duchenne.
Duchenne Heroes share their authentic insights on a new educational website, WeSpeakDuchenne.com, which provides straightforward information to help families navigate the complexities of the Duchenne journey, and a platform to hear from others who have been down the same path.
“Our goal is to make a positive impact in the lives of people living with Duchenne by providing helpful information and uplifting voices from the community,” said Gilberto Gil, Director of Patient and Caregiver Marketing at NS Pharma. “The Duchenne Heroes’ insights and authentic experiences can inspire families who may be navigating a Duchenne diagnosis. It is my hope that these unique perspectives combined with easy-to-understand information about Duchenne Muscular Dystrophy, will make WeSpeakDuchenne.com a valuable online resource for the community.”
WeSpeakDuchenne.com includes educational resources such as a “Duchenne-opedia,” a glossary of useful terms to know, as well as a primer on the importance of increasing dystrophin for people with Duchenne, and a section where caregivers share their responses to commonly asked questions around diagnosis and treatment. The Duchenne Heroes Stories page shines a light on different families’ path to diagnosis and the learnings that helped as they navigate life with Duchenne.
“It means a lot to our family to participate in the Duchenne Heroes program as we know how life-changing a Duchenne diagnosis can be,” said Elizabeth Cojeen, member of the Duchenne Heroes program. “Our son, Emmett, inspires us every day with his bright smile and big personality to stay positive, and we hope sharing our story helps other families do the same.”
Additional Duchenne Heroes stories will be included over time to showcase diverse perspectives around topics relevant to the broader community.
“The biggest lesson I’ve learned since my son Brantley’s Duchenne diagnosis is that there is no clear-cut path or single solution for a lot of life’s transitions,” said Dianna Marlow, member of the Duchenne Heroes program. “Our family’s journey, like everyone else’s, is unique when it comes to things like schooling, independence and accessibility. As Duchenne Heroes, we’re proud to share our experiences if it helps to bring ideas or encouragement to other families.”
In addition to being featured on the website, Duchenne Heroes will share their stories across NS Pharma’s social media platforms (Facebook: @NS Pharma, Inc.; X: @NSPharmaInc.) and make appearances at advocacy events in the coming year.

VILTEPSO® (viltolarsen) injection Four-Year Clinical Trial Data Published in the Journal of Neuromuscular Diseases
Data were from a completed four-year study (up to Week 216) of the open-label extension trial of a VILTEPSO Phase 2 study
NS Pharma, Inc. (NS Pharma; President, Tsugio Tanaka), is a wholly owned subsidiary of Nippon Shinyaku Co., Ltd. (Nippon Shinyaku; President, Toru Nakai)
Paramus, NJ: May 9, 2023 – NS Pharma is pleased to announce that previously reported long-term efficacy and safety data (final visit up to Week 216) from the open-label extension of a Phase 2 study of VILTEPSO® (viltolarsen) have been published in the May issue of the Journal of Neuromuscular Diseases. The article, “Efficacy and Safety of Viltolarsen in Boys With Duchenne Muscular Dystrophy: Results From the Phase 2, Open-Label, 4-Year Extension Study,” is freely available under open access (click here).
“In this extension study it was encouraging to see that, compared to the CINRG DNHS control group, Viltepso-treated patients showed maintenance of motor function through the first two years of treatment and experienced delay of disease progression over the following two years of treatment, whereas the control group declined over this same four-year time period,” said Leslie Magnus, MD, Vice President, Medical Affairs. “NS Pharma is pleased that these data support the role of VILTEPSO as an important treatment strategy for DMD patients who are amenable to exon 53 skipping.”
The data published in the Journal of Neuromuscular Diseases are from an open-label trial (N=16) that is the extension of a previous 24-week Phase 2 trial in North America. All 16 patients aged 4 to
<10 years with DMD amenable to exon 53 skipping at baseline in the 24-week study elected to enroll in this long-term trial to continue evaluation of motor function and safety. Assessments of timed function tests (Time to Stand, Time to Run/Walk, Time to Climb 4 Stairs) were compared to a group- matched DMD historical control drawn from the Cooperative International Neuromuscular Research Group Duchenne Natural History Study (CINRG DNHS). Both groups received a stable dose of glucocorticoid treatment.
Efficacy results at Week 205 for VILTEPSO compared to the CINRG DNHS control group for the primary endpoint of mean change from baseline for Time to Stand was 2.7 seconds vs. 8.3 seconds, respectively.
The most frequently reported adverse events were mild to moderate and included cough, nasopharyngitis, rash, pyrexia, and vomiting. This safety profile was similar to that seen in the previous short-term study. There were no treatment-related serious adverse events and no treatment discontinuations.
About VILTEPSO® (viltolarsen) injection
Prior to its approval in the U.S. in August 2020, VILTEPSO was granted Priority Review as well as Rare Pediatric Disease, Orphan Drug and Fast Track Designations. In March 2020, VILTEPSO was approved in Japan for the treatment of patients with DMD who are amenable to exon 53 skipping therapy. Prior to its approval in Japan, VILTEPSO was granted with the SAKIGAKE designation, Orphan Drug designation, and designation of Conditional Early Approval System.
Indication
VILTEPSO is indicated for the treatment of Duchenne muscular dystrophy (DMD) in patients who have a confirmed mutation of the DMD gene that is amenable to exon 53 skipping. This indication is approved under accelerated approval based on an increase in dystrophin production in skeletal muscle observed in patients treated with VILTEPSO. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial.
Important Safety Information
Warnings and Precautions: Kidney toxicity was observed in animals who received viltolarsen. Although kidney toxicity was not observed in the clinical studies with VILTEPSO, the clinical experience with VILTEPSO is limited, and kidney toxicity, including potentially fatal glomerulonephritis, has been observed after administration of some antisense oligonucleotides. Kidney function should be monitored in patients taking VILTEPSO. Serum creatinine may not be a reliable measure of kidney function in DMD patients.
Serum cystatin C, urine dipstick, and urine protein-to-creatinine ratio should be measured before starting VILTEPSO. Consider also measuring glomerular filtration rate before starting VILTEPSO. During treatment, monitor urine dipstick every month, and serum cystatin C and urine protein-to- creatinine ratio every three months.
Urine should be free of excreted VILTEPSO for monitoring of urine protein. Obtain urine either prior to VILTEPSO infusion, or at least 48 hours after the most recent infusion. Alternatively, use a laboratory test that does not use the reagent pyrogallol red, which has the potential to generate a false positive result due to cross reaction with any VILTEPSO in the urine. If a persistent increase in serum cystatin C or proteinuria is detected, refer to a pediatric nephrologist for further evaluation.
Adverse Reactions: The most common adverse reactions include upper respiratory tract infection, injection site reaction, cough, and pyrexia.
To report an adverse event, or for general inquiries, please call NS Pharma Medical Information at 1- 866-NSPHARM (1-866-677-4276)

NS Pharma Reports on Results of VILTEPSO® (viltolarsen) injection After Four Years of Treatment in Open-Label Extension Trial in Duchenne Muscular Dystrophy
Results were from a final analysis (up to Week 216) of the open-label extension trial of a VILTEPSO Phase 2 study.
In the study, the primary endpoint of Time to Stand and secondary endpoints, including Time to Run/Walk and Time to Climb 4 Stairs, were evaluated in comparison to a group-matched DMD historical control.
PARAMUS, NJ: October 24, 2022 – NS Pharma, Inc. (NS Pharma; President, Tsugio Tanaka), a wholly owned subsidiary of Nippon Shinyaku Co., Ltd. (Nippon Shinyaku; President, Toru Nakai), announced today that long-term efficacy and safety data (final analysis up to Week 216) from the open-label extension of a Phase 2 study of VILTEPSO® (viltolarsen) injection were presented at the 27th International Hybrid Annual Congress of the World Muscle Society (WMS 2022) in Halifax, Nova Scotia, Canada.
“These data represent the longest clinical experience of an exon 53 skipping therapy for the treatment of Duchenne muscular dystrophy. In this four-year study, Viltepso- treated patients maintained motor function over the first two years of treatment and experienced significant delay of disease progression over the following two years, compared with the CINRG DNHS control group which declined over this same time period,” said Leslie Magnus, MD, Vice President, Medical Affairs. “These data are encouraging as NS Pharma continues to evaluate the effect of Viltepso on improving or stabilizing motor function in a Phase 3 study.”
Data presented at WMS 2022 are from an open-label trial (N=16) that is the extension of a previous 24-week Phase 2 trial in North America. All 16 patients aged 4 to <10 years with DMD amenable to exon 53 skipping in the 24-week study elected to enroll in this long-term trial to continue evaluation of motor function and safety. Assessments of timed function tests (Time to Stand, Time to Run/Walk, Time to Climb 4 Stairs) were compared to a group-matched DMD historical control drawn from the Cooperative International Neuromuscular Research Group Duchenne Natural History Study (CINRG DNHS). Both groups received a stable dose of glucocorticoid treatment. Efficacy results at Week 205 significantly favored viltolarsen compared to the CINRG DNHS control group for the primary endpoint of mean change from baseline for Time to Stand (viltolarsen 2.7 seconds vs. 8.3 seconds for CINRG DNHS, p=0.0040), and secondary endpoints including Time to Run/Walk 10 meters (viltolarsen 2.0 seconds vs. 6.0 seconds for CINRG DNHS, p=0.0002), and Time to Climb 4 Stairs (viltolarsen -0.01 m/s vs. -0.13 m/s for CINRG DNHS, p=0.0088).
The most frequently reported adverse events were mild to moderate in this 216-week open-label extension period and included cough, nasopharyngitis, rash, pyrexia, and vomiting. This safety profile was similar to that seen in the previous short-term study. There were no treatment-related serious adverse events and no treatment discontinuations.
“This long-term study gives physicians who treat patients with DMD important information about the long-term impact of VILTEPSO on ameliorating the disease course,” said Paula Clemens, MD, from the University of Pittsburgh School of Medicine. “Further study is ongoing, but these four-year data give confidence that VILTEPSO can be considered an important part of the treatment strategy for patients with DMD whose dystrophin mutations are amenable to exon 53 skipping therapy.”
In addition to this Phase 2 open-label extension study, NS Pharma continues to investigate the efficacy and safety of VILTEPSO in the confirmatory Phase 3 RACER53 trial. This study was initiated in October 2019 and is currently enrolling patients. The purpose of this Phase 3 randomized, double-blind, placebo-controlled trial is to evaluate the efficacy of viltolarsen on functional motor endpoints compared to placebo in patients with DMD amenable to exon 53 skipping.
