👩🍼Hazel Marquart was born with cystic fibrosis, but with none of the disease’s symptoms. Her mother, Stephanie Marquart, started taking Vertex’s therapy Trikafta while she was pregnant, treating her baby in the womb. Endpoints’ senior biopharma correspondent Andrew Dunn looked at the new gap in care created by the success of drugs like Trikafta, and how the Marquarts took matters into their own hands.
Such treatments have changed cystic fibrosis from a death sentence to a manageable chronic condition for the vast majority of patients. But Trikafta is only approved for children aged 2 and up, even though the disease’s damage begins in the womb. Stephanie didn’t want to wait two years to begin her unborn daughter’s treatment. An adult pulmonologist wrote Stephanie a prescription to take the drug during pregnancy, but insurance wouldn’t cover it at first. At the time, Trikafta cost roughly $27,000 for a month’s dosage. Stephanie sourced her first dose via Facebook.
Vertex is not running a clinical trial to test the drug during pregnancy. It has also refused to provide free drug to physicians who’d like to study it in this setting to generate quality data to guide care decisions. Meanwhile, Scott Sagel, a pediatric pulmonologist at Children’s Hospital Colorado, is seeing more and more babies like Hazel. After two and a half years, the toddler still has no complications from the disease. “We are now getting contacted by families on an almost monthly basis,” Sagel told Endpoints. “It is a new frontier for us.”
Sagel is running a prospective, observational study, asking moms who inquire about fetal treatment to enroll, whether or not they actually take any therapy. The Cystic Fibrosis Foundation is also funding an observational study and planning another. Sagel hopes collecting those cases will be helpful, but he doesn’t believe it’s sufficient. Rigorous, controlled clinical trials remain absent. You can read Andrew’s full story here for more details on the Marquarts’
journey and the lack of information about medicine use during pregnancy. |
