a young adult with Prader-Willi syndrome leaves through the door of a clinical trial site

Reflections on the End of a Trial

Submitted by Anne Fricke, mom to Freya (14, living with PWS)

Over a year ago, I signed Freya up for Harmony Biosciences’ TEMPO clinical trial of pitolisant, a medication to treat excessive daytime sleepiness. I had some reservations at first, mostly centered around making the mental shift of having a vibrant mistrust of pharmaceutical companies to then enrolling my 13-year-old into a pharmaceutical trial. If you’re interested in that journey, you can read How We Got Here – Prader-Willi Syndrome Association | USA.

As of today, Freya is 14, starting her second year on pitolisant, and treatment wise, I think it is one of the best things we’ve done for her. I can’t pinpoint the moment the medication started working, but I do remember when I began to reflect on what things were like without it, and how much easier life had become for Freya and us.

With the excessive daytime sleepiness, not only was Freya struggling to participate and missing out on valuable moments in life, but her emotions were tumultuous, unpredictable, and often bigger than the moment required. The constant vigilance of her energy levels, mood, and tone of voice was exhausting. And then one day, several months into the open-label extension, I realized that Freya hadn’t napped in a long time and that my shoulders didn’t feel so tight. It was a very liberating moment.

Now I can’t say it’s a miracle cure. Perhaps it’s that Freya has grown a bit and needs a higher dose. Perhaps there is some factor of her adapting to the medication…I’m not the researcher so it’s not my job to speculate. Freya now takes naps again and has moments of sleepiness, but they’re still nothing like they were. She may fall asleep in class or on a car ride, but the frequency is still far less, and she is most often able to perk right up and rejoin the waking world. I am still immensely grateful for this opportunity and, fingers crossed, our participation in this trial will help other families gain access to the medication.

We just had our final on-site appointment at the Santa Monica trial site (they’re still enrolling if families are interested), and we’ve thankfully been offered the opportunity to continue the trial through another organization. This time, the appointments will be through tele-health and home visits, which, with our three very friendly but somewhat unruly dogs, might be interesting. I will miss the travel adventures that Freya and I had on these trips, the time alone together without the chaos of school schedules and sibling dynamics. I am also grateful she won’t be missing more school and relying on me to help her with math homework. All around, this clinical trial experience and the treatment provided has been an incredible asset to Freya and our family having a better quality of life.
