New Patient Free Trial

Responding to sapropterin dihydrochloride

Not all patients with PKU respond to sapropterin dihydrochloride and so in some cases a trial is required before JAVYGTOR treatment can fully initiate.

  • You are eligible for JAVYGTOR without a trial if you have responded to sapropterin therapy previously.
  • For patients new to sapropterin therapy, the ACMG recommends a trial to assess their responsiveness to the medication.2

New Patient Free Trial *

The JAVYGTOR New Patient Free Trial is available if you have never tried sapropterin dihydrochloride before. The trial will take place over 30 days and will assess if you respond to sapropterin dihydrochloride by closely monitoring your blood phe levels.

During your medication trial you can expect:

  • Free JAVYGTOR Tablets or Powder for Oral Solution for the duration of your trial. Your doctor will talk to you about which form of JAVYGTOR best suits your needs and how much you will need to take each day.
  • A phe-restricted diet, including medical formula, will be prescribed by your clinic and must be carefully followed at all times through the trial.
  • Clinical support from the team at Cycle Vita who are here for you if you have any questions about taking JAVYGTOR, or need advice in following the diet your clinic has set for you.

Trial Welcome Kit

To support you during the New Patient Free Trial you will be provided with a Trial Welcome Kit, which contains everything you will need to provide your clinic with blood samples, as well as useful items such as measuring cups and spoons.

During the trial it is very important that you follow the instructions provided by your clinic as closely as possible so the trial result is accurate. If you have any questions about JAVYGTOR during the trial, the clinical team at Cycle Vita are just a call away.

If you are interested in a sapropterin dihydrochloride trial talk to your doctor about why you think JAVYGTOR would be suited to your needs. To be enrolled into the JAVYGTOR New Patient Free Trial your doctor will need to complete an enrollment form:
