PITTSBURGH, March 28, 2023 /PRNewswire/ -- PANTHERx^® Rare, one of the largest and fastest growing rare pharmacies in the United States, is pleased to announce the launch of Joenja^® (leniolisib), an oral selective small-molecule PI3K delta inhibitor indicated for the treatment of APDS in adult and pediatric patients ages 12 or older.

"Our patients living with rare and devastating diseases deserve the best that medicine can offer. Through innovation and technology, we continue to make a positive impact on the quality of life of those living with rare diseases. We are pleased to add Joenja^® to the list of medications in PANTHERx^® portfolio," said Rob Snyder, president of PANTHERx^® Rare.

Activated Phosphoinositide 3-Kinase-Delta Syndrome, or APDS, is a rare primary immunodeficiency affecting approximately one to two people per million with disease onset occurring as early as infancy. This condition results from a variant in the genes PIK3CD or PIK3R1 with both genes playing a role in the regulation of white blood cell maturation. The presence of a mutation in these genes lead to hyperactivity of the PI3Kδ pathway resulting in a failure for the immune cells (B and T cells) to mature and properly function. Imbalance in the PI3Kδ pathway results in immunodeficiency and dysregulation. Those with APDS may develop recurrent respiratory tract infections, bronchiectasis, lymphoproliferation as well as neurodevelopment delay and failure to thrive. Clinical presentation is highly variable ranging from asymptomatic adults to those suffering from lymphoproliferation or development of profound immunodeficiency.

Snyder explained Joenja^® exerts its effects by blocking the active binding sites of PI3Kδ inhibiting the signaling pathway hyperactivity that leads to dysfunction and dysregulation of B and T cells. In clinical trials, Joenja^® achieved both co-primary efficacy measures of reduction in lymph node size and correction of immunodeficiency in the target population. The most common adverse reactions (>10%) were headache, sinusitis, and atrophic dermatitis.
