MeasureTime frameDescription
Percentage of Participants With Treatment Emergent Adverse Events (TEAEs)From Day 1 until the Final Study Visit (up to Month 49)TEAEs were defined as an AE that occurs after a participant's initial treatment zilucoplan start for this study (RA101495-01.202) that was not present at the time of treatment start, or an AE that increases in severity after treatment start in this study, if the event was present at the time of treatment start.
Percentage of Participants With Serious TEAEsFrom Day 1 until the Final Study Visit (up to Month 49)Serious Adverse event (SAE) was defined as any untoward medical occurrence that:• results in death, • is life-threatening threatening (note that this refers to an event in which the participant was at risk of death at the time of the event; it does not refer to an event that hypothetically might have caused death if it were more severe), • requires hospitalization or prolongation of existing hospitalization, • results in persistent or significant disability/incapacity, and • results in a congenital anomaly/birth defect.

Zilucoplan-Cohort A (Eculizumab Naïve)
Cohort A (Eculizumab Naive) included all participants from study RA101495-01.201 (NCT03078582) who had not received eculizumab for treatment of paroxysmal nocturnal hemoglobinuria (PNH). Participants received a loading dose of 0.3 milligram/kilogram (mg/kg) zilucoplan administered by subcutaneous (SC) injection at Day 1 of this study. Following in-clinic education and training, all participants self-injected 0.1 mg/kg of zilucoplan by SC injection once daily for 12 months. From Week 2 onwards, if a participant had not achieved an adequate response, the zilucoplan dose was escalated to 0.3 mg/kg daily.

Participants received a loading dose of 0.3 mg/kg zilucoplan administered by SC injection at Day 1 of this study. Following in-clinic education and training, all participants self-injected 0.1 mg/kg of zilucoplan by SC injection once daily for 12 months. From Week 2 onwards, if a participant had not achieved an adequate response, the zilucoplan dose was escalated to 0.3 mg/kg daily.

Zilucoplan (Inadequate Responder to Eculizumab)
Inadequate Responder cohort included participants from qualifying study RA101495-01.203 (NCT03030183) who had an inadequate response to eculizumab treatment for PNH. Participants received a loading dose of 0.3 mg/kg zilucoplan administered by SC injection at Day 1 of this study. Following in-clinic education and training, all participants self-injected 0.1 mg/kg of zilucoplan by SC injection once daily for 12 months. From Week 2 onwards, if a participant had not achieved an adequate response, the zilucoplan dose was escalated to 0.3 mg/kg daily.

Change From Baseline in Hemoglobinuria Values at Each Time Point

Hemoglobinuria was assessed using a urine colorimetric scoring system with a score of 1 through 10 where 1 represents no hemoglobinuria and 10 represents maximum hemoglobinuria.

Time frame: Baseline, Month 1, 2, 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39, 42, 45, 48 and Final Study Visit (Month 49)

Population: Safety population included all participants who received at least 1 injection of zilucoplan on or after Day 1 of this extension study. Baseline was generally the final visit of the qualifying study (RA101495-01.201 or RA101495-01.203). Here, Number of participants analyzed included those participants who were evaluable for the assessment and 'n' (Number analyzed) signifies participants who were evaluable at specified time points.

Secondary

Maximum Plasma Concentration (Cmax) of RA101495

Cmax is the maximum plasma concentration.

Time frame: At Day 1, Month 1, 2, 3, 6, 9, and 12

Population: PK population included all participants in the Safety population who had at least 1 plasma sample obtained for PK assessment. Data was not collected and analyzed for this outcome measure due to change in planned analysis.

Secondary

Number of Participants With Anti-drug Antibodies (ADA)

Blood samples collection were planned to analyze for the presence/absence of ADAs to zilucoplan for immunogenicity assessments.

Time frame: At Day 1, Month 1, 2, 3, 6, 9, and 12

Population: Safety population included all participants who received at least 1 injection of zilucoplan on or after Day 1 of this extension study. The planned analysis of immunogenicity (ADA) was not performed as the assay was considered not fit for purpose due to an insufficient level of drug tolerance; therefore, no samples were processed.

Secondary

Plasma Concentrations of RA101495 and Its Major Metabolite(s)

Blood samples of RA101495 (zilucoplan) and its metabolites (RA102758 and RA103488) were collected for Plasma concentration analysis.

Time frame: Predose: At Day 1 (Screening), Month 1, 2, 3, 6, 9, 12, and Final Study Visit (Month 49)

Population: Pharmacokinetic (PK) population included all participants in the Safety population who had at least 1 plasma sample obtained for PK assessment. Here, 'n' (Number analyzed) signifies participants who were evaluable at specified time points.

Time Corresponding to Cmax (Tmax) of RA101495

tmax is the time to corresponding Cmax.

Time frame: At Day 1, Month 1, 2, 3, 6, 9, and 12

Population: PK population included all participants in the Safety population who had at least 1 plasma sample obtained for PK assessment. Data was not collected and analyzed for this outcome measure due to change in planned analysis.

Secondary

Total Complement (CH50) Levels

Blood samples collection were planned to assess complement (CH50) levels. The planned analysis of CH50 was not performed because the CH50 assay was not able to be validated due to lack of reproducibility of the manufacturer's kits.

Time frame: At Day 1, Month 1, 2, 3, 6, 9, and 12

Population: Pharmacodynamic (PD) population included all participants in the Safety population who had at least 1 plasma sample obtained for PD assessment. Data was not collected and analyzed for this outcome measure due to change in planned analysis.
