  8. Vaccination against Neisseria meningitides types A, C, W, Y and B, Streptococcus pneumoniae and Haemophilus influenzae Type B (Hib) either within 2 years prior to Day 1 dosing, or within 14 days after starting treatment with APL-2. Unless documented evidence exists that subjects are non-responders to vaccination as evidenced by titers or display titer levels within acceptable local limits
  9. Women of child-bearing potential (WOCBP) must have a negative pregnancy test at the Screening and Day -28 Visit (Run-in Period) and must agree to use protocol defined methods of contraception for the duration of the study and 90 days after their last dose of study drug

  11. Willing and able to give informed consent
  12. Willing and able to self-administer APL-2 (administration by caregiver will be allowed)
  13. Have a body mass index (BMI) ≤35.0 kg/m2

Exclusion Criteria:

  1. Active bacterial infection that has not resolved within 14 week of Day -28 (first dose of APL-2)
  2. Receiving iron, folic acid, vitamin B12 and EPO, unless the dose is stable, in the 4 weeks prior to Screening
  3. Hereditary complement deficiency
  4. History of bone marrow transplantation
  5. History or presence of hypersensitivity or idiosyncratic reaction to compounds related to the investigational product or SC administration
  6. Participation in any other investigational drug trial or exposure to other investigational agent within 30 days or 5 half-lives (whichever is longer)
  7. Currently breast-feeding women
  8. Inability to cooperate or any condition that, in the opinion of the investigator, could increase the subject's risk of participating in the study or confound the outcome of the study

    This study includes cardiac safety evaluations. The following cardiac eligibility criteria are necessary to avoid confounding the cardiac safety outcomes:

  9. History or family history of Long QT Syndrome or torsade de pointes, unexplained syncope, syncope from an uncorrected cardiac etiology, or family history of sudden death
  10. Myocardial infarction, CABG, coronary or cerebral artery stenting and /or angioplasty, stroke, cardiac surgery, or hospitalization for congestive heart failure within 3 months or greater than Class 2 Angina Pectoris or NYHA Heart Failure Class >2
  11. QTcF > 470 ms, PR > 280 ms
  12. Mobitz II 2nd degree AV Block, 2:1 AV Block, High Grade AV Block, or Complete Heart Block unless the patient has an implanted pacemaker or implantable cardiac defibrillator (ICD) with backup pacing capabilities
  13. Receiving Class 1 or Class 3 antiarrhythmic agents, or arsenic, methadone, ondansetron or pentamidine at screening
  14. Receiving any other QTc-prolonging drugs (see Appendix 4 in Section 19.4), at a stable dose for less than 3 weeks prior to dosing
  15. Receiving prophylactic ciprofloxacin, erythromycin or azithromycin for less than one week prior to the first dose of study medication (must have a repeat screening ECG after one week of prophylactic antibiotics with QTcF < 470 ms)
