2. A biopsy has confirmed diagnosis of primary C3G or IC-MPGN or patient has a
biopsy-proven histologic recurrence in posttransplant.
3. There is evidence of active renal disease, based on at least 1 g/day of proteinuria
from 24-hour urine collection or uPCR =1 g/g from random urine in native kidney. There
is no minimum level of proteinuria for post-transplant recurrence.
4. Patient has a limited response to treatment regimens for C3G/IC-MPGN, and may include:
1. Angiotensin-converting enzyme inhibitor, angiotensin receptor blocker, and/or
sodium-glucose cotransporter-2 inhibitor therapy
2. Other medications that can affect proteinuria (eg, steroids, mycophenolate
mofetil, and/or other immunosuppressants that the patient is receiving for
treatment of C3G or IC-MPGN)
5. Patient has received vaccinations against S pneumoniae, N meningitidis (types A, C, W,
Y, and B), and H influenzae (type B) as per the Advisory Committee on Immunization
Practices (ACIP) recommendations for adults or children with complement deficiencies.
Vaccination series should be initiated at least 14 days prior to enrollment. If
patient disease is severe and requires immediate treatment, administer required
vaccine as soon as possible and provide patients with 2 weeks of prophylactic
antibiotics.
6. Female patients of childbearing potential, defined as any women who have experienced
menarche and who are not permanently sterile or postmenopausal, must have negative
blood pregnancy tests at screening (and negative urine pregnancy tests on day 1) and
must agree to use protocol-defined methods of contraception from screening through at
least 90 days after receiving the last dose of pegcetacoplan.
7. Patients above the legal age of consent, in accordance with local regulations, must be
willing and able to provide informed consent. The legally authorized representative of
patients under the legal age of consent must be willing and able to provide informed
consent; where appropriate, patients under the legal age of consent must also give

9. Patient currently resides in and is a resident of the US.
Exclusion Criteria:
1. C3G/IC-MPGN is secondary to another condition (eg, infection, malignancy, monoclonal
gammopathy, a systemic autoimmune disease such as systemic lupus erythematosus,
chronic antibody-mediated rejection, or a medication), in the opinion of the treating
physician.
2. Patient has current or prior diagnosis of HIV, hepatitis B, or hepatitis C infection
or positive serology during screening that is indicative of infection with any of
these viruses.
3. Patient's body weight is greater than 100 kg at screening.
4. Patient has hypersensitivity to pegcetacoplan or to any of the excipients.
5. Patient has history of meningococcal disease.
6. Patient has a severe infection (eg, requiring IV antibiotic therapy) within 14 days
prior to the first dose of pegcetacoplan.
7. Patient has an absolute neutrophil count less than 1000 cells/mm3 at screening.
8. Patient has other significant renal disease.
9. Based on the investigator's opinion, the patient has significant glomerulosclerosis or
interstitial fibrosis on kidney biopsy.
10. Patient is participating in any other investigational drug trial.
11. Patient is a female who is pregnant or who is currently breastfeeding.
12. Patient has the inability to cooperate or has any condition that, in the opinion of
