Vanda Pharmaceuticals Acquires U.S. and Canadian Rights to PONVORY® (ponesimod), a Selective S1P1R Modulator Approved for Patients with Relapsing Multiple Sclerosis
WASHINGTON, Dec. 7, 2023 /PRNewswire/ -- Vanda Pharmaceuticals Inc. (Vanda) (Nasdaq: VNDA) today announced that it has acquired U.S. and Canadian rights to PONVORY® (ponesimod) from Actelion Pharmaceuticals Ltd. (Janssen), a Johnson & Johnson Company. PONVORY® is approved by the U.S. Food and Drug Administration (FDA) and Health Canada to treat adults with relapsing forms of multiple sclerosis (RMS), to include clinically isolated syndrome, relapsing-remitting disease and active secondary progressive disease. PONVORY® has a proven safety profile with over 10 years of data.
"The acquisition of Ponvory is a significant milestone for Vanda, as it expands our commercial portfolio and gives us access to a versatile immune response modifier that can potentially have broad application in treating a number of autoimmune-based disorders," said Mihael H. Polymeropoulos, M.D., Vanda's President, CEO and Chairman of the Board.
In a clinical study, PONVORY® was shown to be superior to Aubagio®, another approved drug for multiple sclerosis (MS), in the annual rate of relapse and it was also associated with fewer T2 and T1 MRI lesions versus the comparator. Approximately 9 out of 10 people taking PONVORY® did not experience disability progression over 2 years (as measured by the time to 3-month Confirmed Disability Progression).1
The effect of PONVORY® on the decrease of circulating lymphocytes is reversible so lymphocytes quickly return to baseline levels after discontinuation of PONVORY®. This rapid reversible effect is important for people needing to pause therapy for a vaccine. For women of childbearing age who want to become pregnant, PONVORY® is eliminated from the body in about 7 days after stopping treatment.
The mechanism of action of PONVORY® makes it also a potential therapeutic candidate for the treatment of a diverse group of inflammatory/autoimmune disorders ranging from psoriasis to ulcerative colitis. In a randomized placebo controlled clinical study, PONVORY® has also been shown to reduce the symptoms and signs of psoriasis.2
Under the terms of the agreement, Vanda paid $100 million to acquire the U.S. and Canadian rights to PONVORY®. Janssen will continue to operate the business pursuant to a Transitional Business License Agreement, during which time, Vanda and Janssen will transition regulatory and supply responsibility for PONVORY® to Vanda.
Stifel acted as exclusive financial advisor to Vanda with respect to this acquisition.
About PONVORY®
PONVORY® (ponesimod) is a daily oral selective sphingosine-1-phosphate receptor 1 (S1P1R) modulator, indicated to treat adults with relapsing forms of MS, to include clinically isolated syndrome, relapsing-remitting disease and active secondary progressive disease. PONVORY® blocks the capacity of lymphocytes to egress from lymph nodes, reducing the number of lymphocytes in peripheral blood. PONVORY® does not require genetic testing or first-dose cardiac monitoring for most patients. Because initiation of PONVORY® treatment results in a decrease in heart rate, first-dose monitoring is recommended in patients with certain preexisting cardiac conditions.

The PONVORY® Orange Book listed patent with the latest expiry date is set to expire in December 2035.
About Multiple Sclerosis
MS is a chronic autoimmune inflammatory disease of the central nervous system (CNS) in which immune cells attack myelin (the protective casing that insulates nerve cells), damaging or destroying it and causing inflammation. This affects how the CNS processes information and communicates with the rest of the body, causing the neurologic signs and symptoms of MS. Symptoms vary by person, but common symptoms include fatigue, balance and walking problems, numbness or tingling, dizziness and vertigo, vision problems, bladder and bowel problems and weakness.
About Sphingosine-1-Phosphate Receptor 1 Modulators
PONVORY® (ponesimod) belongs in the molecular class of sphingosine-1-phosphate (S1P) analogs that act as modulators of the S1P receptor (S1PR). There are five S1PR (1-5) subtypes with different tissue distribution and functional specificity. PONVORY® is a selective ligand for the S1P1R subtype. It has been speculated that selectivity for S1P1R, rapid onset and reversibility of pharmacological effects, and an optimized titration regimen may differentiate ponesimod from fingolimod, the first of the oral S1PR modulators in the treatment of multiple sclerosis, and may lead to better safety and tolerability.3 Besides fingolimod (FDA approved in 2010), there are four additional FDA-approved members in the S1P modulator class that include siponimod (2019), ozanimod (2020), ponesimod (2021) and etrasimod (2023). With the exception of etrasimod, all other drugs are currently approved for the treatment of MS. Ozanimod and etrasimod are approved for the treatment of ulcerative colitis.
The S1PR modulators act by preventing the egress of lymphocytes from the lymph nodes and as such reduce the number of circulating lymphocytes leading to a decrease of the autoimmune response at the target site.
Based on the latest Datamonitor market forecasts for multiple sclerosis and ulcerative colitis, the S1P market in the U.S. is expected to be approximately $2 billion in 2024 and to grow to approximately $3.5 billion in 2028.4
