When Cooper Norris was just two years old, his pediatrician noticed some freckling and café au lait spots on his back. The pediatrician told his parents, Kirsta and Michael, they would need to monitor this. But by age four, Cooper had developed a lump on the left side of his neck. An ultrasound of the lump led the family to a geneticist who confirmed that it was a benign tumor called a plexiform neurofibroma (PN) caused by neurofibromatosis type 1 (NF1) – a neurogenetic condition caused by mutations in the NF1 gene, which can be inherited or occur spontaneously.
“We were surprised when the doctor told us to come back in a year to monitor the disease, because nothing else could be done – the tumor was inoperable and there were no approved treatments – and that was not really acceptable to us as we are not ‘wait and see’ kind of parents,” Kirsta recalls.
Despite its designation as a rare disease, NF1 is one of the most common inherited neurological disorders affecting one out of every 3,000. Symptoms of NF1, including soft lumps on and under the skin, and pigmentation (called “café-au-lait” spots), typically begin in early childhood. In up to 50% of patients, PN tumors, like Cooper’s, may develop on the nerve sheaths. PNs can lead to complications such as pain, disfigurement and airway dysfunction.
As Cooper’s tumor continued to grow, he experienced pain when he was hugged or turned his head to look for traffic while riding his bike. The tumor was doubling in size every 18 months and there was a risk that it might obstruct his airflow. “That’s when we knew we had to take that next step and become advocates for Cooper to find him the very best care and explore all the options that were out there,” Michael says.
Kirsta and Michael took Cooper to a leading geneticist and NF1 expert who helped enroll Cooper in a clinical trial for an investigational oral therapy for the treatment of NF1 PNs.
After the first three months of taking the treatment, Cooper’s tumor began to get smaller. Six months after starting treatment, his tumor shrunk 20%. He experienced nausea, mouth sores, and toenail redness from the treatment. All patients were different and Cooper’s experience with treatment may not have been the experience of all patients. “We were able to go from not knowing what to expect to seeing the tumor decrease in size, and that really changed our optimism and gave us hope” Kirsta shares.
The treatment Cooper received through the clinical trial was recently approved by the FDA for the treatment of children aged two years and older with neurofibromatosis type 1 (NF1) who have plexiform neurofibromas that cannot be completely removed by surgery. He takes it twice a day as a capsule and continues to get regular MRIs to monitor his condition. Today, Cooper, now 8, enjoys doing things that were sometimes difficult before like riding bikes with his brother, going to theme parks, watching his favorite films and playing games.
“Fortunately for Cooper, the treatment has reduced his tumor size at a time where kids are starting to be aware of differences,” Kirsta says. “It’s not that all our stress has been removed, but we try to focus on having an attitude of gratitude and being thankful.”
