* Have a body mass index (BMI) =35.0 kg/m2
Minimum age
18 Years
Maximum age
No limit

Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
* Active bacterial infection that has not resolved within 14 week of Day -28 (first dose of APL-2)
* Receiving iron, folic acid, vitamin B12 and EPO, unless the dose is stable, in the 4 weeks prior to Screening
* Hereditary complement deficiency
* History of bone marrow transplantation
* History or presence of hypersensitivity or idiosyncratic reaction to compounds related to the investigational product or SC administration
* Participation in any other investigational drug trial or exposure to other investigational agent within 30 days or 5 half-lives (whichever is longer)
* Currently breast-feeding women
* 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:

* 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
* 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
* QTcF > 470 ms, PR > 280 ms
* 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
* Receiving Class 1 or Class 3 antiarrhythmic agents, or arsenic, methadone, ondansetron or pentamidine at screening
* 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
* 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)
