PHARM announces that its Marketing Authorisation Application (MAA) for leniolisib has been validated for scientific evaluation under an accelerated assessment by the European Medicines Agency (EMA).
FREMONT, CA: Pharming Group N.V. Pharming ( PHAR: NASDAQ) declares that the European Medicines Agency's (EMA) Committee for Medicinal Products for Human Use has validated its Marketing Authorization Application (MAA) for leniolisib for scientific evaluation as part of an expedited review (CHMP).

The application, which was initially submitted in October 2022, is for the investigational drug leniolisib, an oral, selective phosphoinositide 3-kinase delta (PI3K) inhibitor, to be used as a treatment for adolescents and adults 12 years of age and older who have activated phosphoinositide 3-kinase delta syndrome (APDS), a rare primary immunodeficiency.
The leniolisib MAA received an accelerated review from the EMA's CHMP, according to Pharming. The accelerated evaluation shortens the review period from 210 days to 150 days. Suppose the product is deemed to be of significant significance for public health, particularly from the perspective of therapeutic innovation. In that case, EMA will agree to expedite the review of an MAA upon request. In the first half of 2023, leniolisib is expected to receive marketing authorisation in the European Economic Area.
Positive results from a leniolisib Phase II/III study published on February 2, 2022, met its co-primary endpoints of decreased lymph node size and increased percentage of naive B cells in patients with APDS, providing support for the MAA. Furthermore, the study's safety data revealed that subjects tolerated leniolisib well. Data from a lengthy, open-label extension clinical trial, including leniolisib treatment in APDS patients, were also included in the MAA.
The fact that the EMA approved the review of MAA via an accelerated assessment pathway underlines Pharming's continuous dedication to leniolisib as a focused therapy for people with APDS who are adults or adolescents 12 years of age or older. They believe that leniolisib will meet the demand for APDS patients who now receive supportive therapies to manage their main symptoms. This review marks a significant turning point in Pharming's mission to bring leniolisib to medical professionals and the patients they treat anywhere in the world. Throughout the regulatory process, we are eager to work with EMA as necessary.
A primary immunodeficiency that is uncommon, affecting 1–2 individuals per million, APDS. Variants in either of the two genes, PIK3CD or PIK3R1, which control the development of white blood cells, are the root cause of APDS. Variants of these genes cause hyperactivity of the PI3K phosphoinositide 3-kinase delta pathway. For the immune system to operate normally, the PI3K pathway needs to be signalled in a balanced manner. Immune cell maturation and function are compromised when this system is overactive, which causes immunodeficiency and dysregulation. Serious, recurrent sinopulmonary infections, lymphoproliferation, autoimmunity, and enteropathy are the hallmarks of APDS.
People with APDS experience a median 7-year diagnostic delay due to the symptoms' wide range of possible causes, including various primary immunodeficiencies. This delay could result in increased harm over time, including lymphoma and chronic lung damage, because APDS is a progressive disease. Genetic testing is the only reliable way to diagnose this illness.
