Treatment with Sephience must be initiated and supervised by a physician experienced in the treatment of PKU. Posology The recommended dose (mg/kg/day) of Sephience to be administered orally once daily is based on age and body weight (see Table 1).
The maximum recommended dose is 60 mg/kg/day. The recommended dose of Sephience in patients ≥ 2 years of age is 60 mg/kg/day. However, the dose may be adjusted to a lower dose if the treating physician considers it necessary or appropriate.
5, 15, 30, and 60 mg/kg/day). 4 5 * Instead of four 250 mg sachets, one full 1 000 mg sachet can be mixed with 36 mL of water or apple juice. This mixture should be administered with a syringe, according to the volume to be administered detailed in Table 5.
Recommended dose of Sephience oral powder in sachet by body weight for patients 2 years and older and weighing more than 16 kg The recommended dose is 60 mg/kg/day. The calculated daily dose should be rounded to the nearest multiple of 250 mg or 1 000 mg, as appropriate.
For instance, a calculated dose of 1 251 to 1 374 mg should be rounded down to 1 250 mg corresponding to 1×250 mg sachet and 1×1 000 mg sachet. A calculated dose of 1 375 to 1 499 mg should be rounded up to 1 500 mg corresponding to 2×250 mg sachets and 1×1000 mg.
Missed dose A missed dose should be taken as soon as possible. The normal dosing schedule should be resumed the following day. Discontinuation of treatment In the pivotal Phase 3 clinical study, a threshold of 15% or greater reduction in blood phenylalanine (Phe) levels was utilised for determination of response.
No controlled efficacy and safety data are available in patients who do not experience a reduction of 15% or greater reduction in blood Phe levels after receiving sepiapterin for 14 days. The determination of responsiveness for a patient with PKU and the discontinuation of the medicinal product is at the discretion of the treating physician.
