Pharma (“LogixX”) are delighted to announce the official launch of Sapropterin Dihydrochloride
(“Sapropterin”) in the United Kingdom.

Sapropterin Dihydrochloride, a generic equivalent to Kuvan®, is now available in all dosage forms,
including sugar free soluble tablets of 100mg strength. What makes this launch even more noteworthy is
the introduction of Sapropterin Dihydrochloride in powder form for oral solution, available in 100mg and
500mg strengths, marking the first-ever release of this formulation in the UK.

Marc-Olivier Geinoz, CEO of Dipharma, expressed his enthusiasm, stating, “After successfully introducing
Sapropterin Dipharma in several major European countries, we are excited to announce its launch also in
the UK. This achievement is the result of a strong collaboration with our esteemed UK partner, LogixX.
Starting today, patients in the UK will have access to Sapropterin Dihydrochloride in the convenient
powder for oral solution form. This innovative formulation, which dissolves 25 times faster than tablets,
represents a significant advancement in patient compliance and their overall quality of life. Dipharma and
LogixX remain steadfast in their commitment to supporting the PKU and BH4 deficiency community, with
a continued presence in the UK territory and active engagement with healthcare professionals.”

Dipharma.”

About BH4-responsive phenylketonuria and BH4 deficiency

PKU is a rare, genetic metabolic disorder that affects an estimated 1 in 7000+ newborn infants. In those
affected, there is a reduction in the activity of the enzyme phenylalanine hydroxylase (PAH). This defect
impairs the degradation of the amino acid phenylalanine (Phe) into tyrosine (Tyr) and promotes
hyperphenylalaninemia. Left untreated, hyperphenylalaninemia can lead to progressive and irreversible
central nervous system damage. This deficiency manifests as mental and physical impairments, such as
loss of emotionality and inappropriate changes in behavior. Nowadays, PKU can be diagnosed and treated
early through newborn screening. In addition, PKU is linked to another rare condition, tetrahydrobiopterin
(BH4) deficiency disorder (incidence of 1 to 2 in 1,000,000). Here, the synthesis or regeneration of BH4,
the essential cofactor of PAH, is impaired. This results in hyperphenylalaninemia and a deficiency of the
monoamine neurotransmitters, dopamine, serotonin, noradrenaline and epinephrine. The effects on
those affected by these conditions depend on a particular genetic mutation that underlies the disease.

About Sapropterin

Sapropterin dihydrochloride is a synthetic version of the naturally occurring 6R-BH4, which is a cofactor
of the hydroxylases for phenylalanine, tyrosine and tryptophan. Sapropterin formulations are
administered to patients with BH4-responsive phenylketonuria and BH4 deficiency. In patients with
phenylketonuria, sapropterin enhances the activity of the defective phenylalanine hydroxylase and
thereby increases or restores the oxidative metabolism of phenylalanine (“Phe”) sufficiently to reduce or
maintain blood Phe levels, prevent or minimize further Phe accumulation, and increase tolerance to Phe
intake in the diet. In patients with BH4 deficiency, sapropterin formulations complements the deficient
levels of BH4, thereby restoring the activity of phenylalanine hydroxylase.
