Brief Summary

The proposed study, NM8074-PNH-101, is a phase II, open-label, multi-dose, unicenter trial to evaluate the safety and efficacy of NM8074 in Soliris-treated PNH subjects.

  Up to Week 12

• Normalization of anemia

  Up to Week 12

  Up to Week 12

Study Arms (1)

NM8074

EXPERIMENTAL

All subjects will receive a dose of 15 mg/kg NM8074 every two weeks with a total of 6 doses, from Day 1 to Day 84 during the treatment period.

Drug: NM8074

Interventions

NM8074 DRUG

NM8074 will be administered as an intravenous infusion. All enrolled subjects will receive a dose of 15 mg/kg NM8074 once every two weeks for a total of 6 doses from Day1 to Day 84. For Soliris-treated PNH subjects, admission and dosing of NM8074 on Day 1 should be scheduled to coincide with the next scheduled dose of Soliris (i.e., 14 ± 2 days after the last Soliris dose). Soliris should NOT be administered on Day 1 or at any time thereafter during course of the study. Subjects in the treatment groups will receive a dose of 15 mg/kg of NM8074 on Day 1, which will be administered during the study visit by the site staff. During the remainder of the treatment period, subjects will be given another 15 mg/kg dose every two weeks at approximately the same time. On days of scheduled study visits at the Investigation Site, the dose must be administered after blood work is completed.

• Presence of one or more of the following PNH-related signs or symptoms within 3 months of Screening: fatigue, hemoglobinuria, abdominal pain, shortness of breath (dyspnea), anemia: hemoglobin \< 10 g/dL, history of a major adverse vascular event (including thrombosis), dysphagia, erectile dysfunction, PNH-mediated pRBC transfusions
• PNH patients must be undergoing treatment with Soliris for at least 3 months prior to screening, and must have a lactate dehydrogenase (LDH) level ≥ 1.5 times the upper limit of normal (ULN) during Screening
• Willing and able to understand and complete informed consent procedures, including signing and dating the informed consent form (ICF), and comply with the study visit schedule.
• Female subjects of childbearing potential must have a negative pregnancy test at Screening, and must not be planning pregnancy throughout the extent of the study term
• Female subjects of child-bearing potential and all male subjects must agree to use of effective contraception during study
• Soliris treated individuals must be able to provide documentation of vaccination against meningococcal infections.

You may not qualify if:

• Platelet count \< 30,000/µL at Screening
• Absolute neutrophil count (ANC) \< 500 cells/µL at Screening
• Body weight \< 85 lbs. (38 kg) at Screening
• Estimated glomerular filtration rate of \< 30 mL/min/1.73m2 based on modification of diet in renal disease (MDRD) equation, creatinine clearance, or CKD-EPI (Chronic Kidney Disease Epidemiology Collaboration) at Screening
• Elevation of liver function tests: alanine aminotransferase (ALT) \> 2xULN or direct bilirubin and alkaline phosphatase (ALP) both \> 2xULN
• Has a known history of meningococcal disease or N. meningitidis infection
• Has an immunological disorder, such as, but not limited to, human immunodeficiency virus (HIV) infection (as evident by HIV-1 or HIV-2 antibody titer) or any acute or chronic infection including, but not limited to, hepatitis B virus (HBV) or hepatitis C virus (HCV)
• Currently active systemic infection or suspicion of active bacterial, viral, or fungal infection that requires antibiotic, antifungal, antiparasitic, or antiviral mediations
• Temperature \> 38°C for more than two weeks prior to screening
• History of bone marrow or solid organ transplantation
• Pregnant, planning to become pregnant, or nursing female subjects
• Recent surgery requiring general anesthesia within the 2 weeks prior to Screening, or expected to have surgery requiring general anesthesia during the 12-week treatment period
• Active malignancy requiring surgery, chemotherapy, or radiation within the prior 12- months (subjects with a history of malignancy who have undergone curative resection or otherwise not requiring treatment for at least 12-months prior to screening with no detectable recurrences are allowed)
• History of any significant major medical conditions (cardiac, pulmonary, renal, e endocrine, or hepatic), or psychiatric disorder that, in the opinion of the Investigator, would make the subject unsuitable for participation in the study
• PNH patients currently under complement blocker treatments other than Soliris
