Primary Outcome Measures :
- Change From Baseline in Blood C3 levels at Day 14 [ Time Frame: Baseline, Day 14 ]
Secondary Outcome Measures :
- Serious Adverse Events (SAEs), Grade 3 or Higher Adverse Events (AEs), and AEs Leading to Discontinuation [ Time Frame: up to Day 49 ]
- Time (in Days) to Achieving Peak C3 Levels From the First Day of Dosing [ Time Frame: Day 14 ]
- Pharmacokinetics: Area Under the Curve (AUC) [ Time Frame: Days 1 & 7 ]
- Pharmacokinetics: Maximum Plasma Concentration (Cmax) [ Time Frame: Days 1 & 7 ]
- Profile of Pharmacokinetics: Time to maximum concentration (Tmax) [ Time Frame: Days 1 & 7 ]
- Change from Baseline in Biomarkers of Alternative Pathway (AP) activity (AP Wieslab, factor D, and Bb) [ Time Frame: Baseline, Day 14 ]
- Relationship between ACH-0144471 exposure and changes in C3 levels and other biomarkers of alternative pathway activity (AP Wieslab, factor D, and Bb) [ Time Frame: Day 14 ]

Criteria
Inclusion Criteria:
- Must have a clinical diagnosis of C3G (C3 glomerulonephritis [C3GN] or dense deposit disease [DDD], the 2 types of C3G) or idiopathic immune-complex membranoproliferative glomerulonephritis (IC-MPGN) by renal biopsy for at least 3 months prior to dosing, with the pathologic diagnosis verified by review of the renal biopsy by the study central pathologist
- C3 must be <50% of the lower limit of normal
- C4 must be >90% of the lower limit of normal
- Must be willing to comply with study-specific vaccination requirements for Haemophilus influenzae, Streptococcus pneumoniae, and Neisseria meningitidis strains A, C, W, and Y
- Negative pregnancy test for females prior to dosing and throughout the study
Exclusion Criteria:
- History of a major organ transplant (e.g., heart, lung, kidney, liver) or hematopoietic stem cell/marrow transplant. Individuals receiving renal replacement therapy are also excluded
- Evidence of monoclonal gammopathy of unclear significance (MGUS), infections, malignancy, autoimmune diseases, or other conditions to which C3 glomerulopathy or IC-MPGN may be secondary
- Estimated glomerular filtration rate (eGFR; using MDRD equation) <45 mL/min/1.73 m2 at the time of screening or at any time over the preceding four-weeks
- Receipt of eculizumab at any dose or interval within the past 75 days prior to dosing
- Use of tacrolimus or cyclosporine within 2 weeks of the first dose of ACH-0144471
- History of febrile illness, a body temperature >38°C, or other evidence of a clinically significant active infection, within 14 days prior to study drug administration
- History of meningococcal infection, or a first-degree relative or household contact with a history of meningococcal infection
- Females who are pregnant, nursing, or planning to become pregnant during the study or within 90 days of study drug administration or patients with a female partner who is pregnant, nursing, or planning to become pregnant during the study or within 90 days of study drug administration
NOTE: Additional inclusion/exclusion criteria may apply, per protocol.
