The UK’s Medicines and Healthcare products Regulatory Agency (MHRA) has approved leniolisib phosphate (Joenja) as the first treatment for activated phosphoinositide 3-kinase delta syndrome (APDS).
This rare immune disorder, which affects both children and adults, can now be managed more effectively thanks to this groundbreaking approval, offering new hope for those living with the disease.
A Landmark Approval for a Rare Condition
On September 25, 2024, the MHRA granted its approval for leniolisib phosphate, making it the first medicine available to treat APDS in adults and adolescents aged 12 years and older, weighing 45kg or more.
APDS, a genetic disorder that severely weakens the immune system, leaves patients prone to repeated infections and other serious complications. The new treatment provides a much-needed option for patients to improve their quality of life.
Leniolisib’s approval follows a fast-track process under the International Recognition Procedure (IRP), which allowed the MHRA to work closely with the US Food and Drug Administration (FDA).
This partnership sped up the process, ensuring the medicine was approved quickly without compromising safety or effectiveness.
What is APDS?
APDS is a genetic disorder where the immune system, meant to defend the body, doesn’t function properly. Patients with this rare condition experience recurrent infections, particularly in the lungs, and often struggle to grow and develop normally.
Long-term, untreated APDS can lead to life-threatening conditions like bronchiectasis, and some patients may develop blood cancers such as lymphoma.
The approval of leniolisib marks a turning point for people living with APDS. The medicine works by correcting the underlying immune defect, allowing the body to fight infections more effectively.
In clinical trials, patients experienced notable reductions in symptoms, with improvements in lymph node size and immune system function.
A New Hope for APDS Patients
Leniolisib phosphate (Joenja) offers a lifeline for patients with APDS, providing a targeted treatment option where previously none existed. The recommended dose is one tablet, taken twice daily, 12 hours apart.
This medicine has undergone rigorous testing, including a placebo-controlled study involving 31 adult and adolescent patients. The trial results were promising: patients who received leniolisib saw significant improvements by day 85.
The Road to Approval
The MHRA’s approval process for leniolisib relied on evidence from trials conducted in collaboration with international regulatory bodies. This marks the first time that the MHRA has used the International Recognition Procedure to fast-track a medicine for a rare disease.
According to Julian Beach, MHRA Interim Executive Director of Healthcare Quality and Access,
“Approval of leniolisib through the IRP means we have facilitated access for people suffering from this serious disease to an effective medicine.”

MHRA’s Commitment to Safety
Leniolisib, like all newly approved medicines, will undergo close safety monitoring. The Medicines and Healthcare products Regulatory Agency (MHRA) reassures the public that their team will continuously review leniolisib’s safety and effectiveness as patients start treatment.
If patients experience side effects, they should report them through the MHRA’s Yellow Card scheme, which plays a vital role in identifying safety issues. This scheme helps improve the safety of medicines and medical devices for everyone.
A Step Forward in Rare Disease Treatment
The approval of leniolisib in the UK brings optimism for rare disease patients, offering an opportunity to manage the life-threatening symptoms of APDS.
With the MHRA’s fast-track approval process, the UK is helping patients access innovative treatments sooner.
“We are focused on providing UK patients access to safe and effective medicines in the shortest possible time,” Beach added.
This is just the beginning for APDS patients, and the future looks brighter with new treatments on the horizon.
