Myelodysplastic Syndrome Clinical Trial
A Study of Pegcetacoplan in Pediatric Patients With Paroxysmal Nocturnal Hemoglobinuria (PNH)
Summary
The purpose of this study is to evaluate the safety, effectiveness, and biological activity (how the investigational medication is processed by the body) of pegcetacoplan in 12-17 year-olds (adolescents) who have paroxysmal nocturnal hemoglobinuria (PNH).
Full Description
This is an open-label study to evaluate pegcetacoplan in people with PNH who are 12-17 years old. The study will consist of a 4-week screening period followed by a 16-week treatment period. Participants switching from a C5 inhibitor will have an additional 4 week run-in period between the screening and treatment periods. At the completion of the study treatment period, participants will either enter a long-term extension period or a 2-month follow-up period.
All eligible study participants will receive pegcetacoplan, administered via subcutaneous infusion twice a week at home. The subcutaneous infusion requires two small needles to be inserted into the fatty layer of tissue under the skin and the investigational medication will flow into the body. Study participants and/or caregivers will be trained on home administration of pegcetacoplan.
Eligibility Criteria
Inclusion Criteria:
Are 12-17 years old at the time of screening
Weigh at least 20 kg (approx. 44 lbs)

EITHER:
Not being treated with an approved complement inhibitor (eculizumab or ravulizumab) prior to start of pegcetacoplan dosing, AND have hemolytic anemia. Hemolytic anemia is defined as hemoglobin (Hb) less than the lower limit of normal (Hb < LLN) and LDH >1.5 times the upper limit of normal (ULN); OR
Currently receiving treatment with an approved complement inhibitor (eculizumab or ravulizumab) AND have evidence of ongoing anemia. Ongoing anemia is defined as Hb < LLN and ARC > ULN
Have a platelet count >75,000/mm3 and an absolute neutrophil count >1000/mm3
Exclusion Criteria:
Are an adult, 18 years of age or older, with PNH
Known or suspected hereditary fructose intolerance (HFI)
History of hereditary complement deficiency, bone marrow transplant, or meningococcal disease (meningitis, bacteremia or septicemia)
