Business Context and Reporting Period
Company: Pharming Group N.V.
Filing Type: Form 6-K (Report of Foreign Private Issuer)
Date: September 11, 2026
Context: The filing announces a significant regulatory milestone: the U.S. Food and Drug Administration (FDA) approved a supplemental New Drug Application (sNDA) for Joenja® (leniolisib). This approval expands the drug's indication to include children aged 4 to 11 years weighing at least 27 kg with activated phosphoinositide 3-kinase delta syndrome (APDS). Joenja is now the first FDA-approved treatment for this specific pediatric population in the U.S.

Outlook, Risks, and Management Commentary
Management Commentary
Management emphasizes that early intervention is critical for children with APDS to prevent irreversible complications. The Chief Commercial Officer stated the immediate priority is supporting physicians and families to ensure rapid and responsible treatment access.
Risks and Contingencies
- Safety Warnings: Joenja may cause fetal harm; pregnancy status must be verified prior to treatment. It is not recommended for patients with moderate to severe hepatic impairment.
- Adverse Events: Common reactions in the newly approved pediatric group include abdominal pain, cough, and respiratory tract infection. Neutropenia (ANC 500-1500 cells/microL) occurred in 63% of pediatric patients in the study, though no associated infections were reported.
- Forward-Looking Statements: The filing includes standard disclaimers that actual results may differ materially from expectations due to risks related to clinical trials, regulatory approvals, and commercial prospects.
