A
Hemolytic Toxicity
SAFETY CONCERN: Highly hemolytic - cannot be administered systemically. Internal use contraindicated. Topical absorption negligible. Limits use to topical applications only.

A
Hemoglobin Improvement vs Eculizumab
PEGASUS Phase III trial: Pegcetacoplan significantly superior to eculizumab for hemoglobin improvement (p<0.001). First therapy to demonstrate superiority over standard C5 inhibitor treatment in PNH.
large↑Improves
A
Transfusion Independence
PEGASUS trial: 85% of pegcetacoplan patients transfusion-free at 16 weeks vs 15% on eculizumab (p<0.001). Dramatic reduction in transfusion requirements.
large↑Improves
A
Extravascular Hemolysis Control
Unique mechanism: C3 inhibition prevents C3b opsonization, controlling extravascular hemolysis that C5 inhibitors cannot address. Addresses key limitation of prior PNH treatments.
large↑Improves
A
Complement-Inhibitor-Naive PNH
PRINCE Phase III trial: Superior to supportive care in treatment-naive PNH patients. Achieved hemoglobin stabilization and LDH reduction. Approved for both naive and C5i-experienced patients.
large↑Improves
A
Safety Profile
Well-tolerated in clinical trials. Most common AEs: injection site reactions, infections. Requires vaccination against encapsulated bacteria (meningococcal, pneumococcal). Self-administered subcutaneously.
moderate↑Improves
C
White Blood Cell Count
An RCT of 105 patients with leukopenia found sodium copper chlorophyllin tablets (60 patients) improved peripheral white blood cell counts over 1 month compared to leucogen and placebo controls. A separate animal study in aplastic anemia mice showed effects on mesenchymal stem cell function. Limited to a single human RCT.

C
Erythrocyte Membrane Integrity
Human studies showed L-cysteine supplementation preserved erythrocyte membrane acetylcholinesterase and Na+,K+-ATPase activities and protected G6PD activity from reduction during exercise-induced oxidative stress.

D
Iron Status
Limited human research suggests histidine supplementation may improve iron status and enhance iron absorption in iron-deficiency anemia. Biochemically, histidine is critical for hemoglobin structure and oxygen binding, and animal studies confirm its importance in hemoglobin synthesis. Evidence remains preliminary with no large controlled trials.

D
Hemoglobin Synthesis
Animal studies demonstrate histidine is essential for hemoglobin synthesis, and histidine deficiency causes growth retardation. The imidazole side chain of histidine plays a critical structural role in hemoglobin's oxygen-binding capacity. Human supplementation data supporting improved hemoglobin levels is very limited.

D
Red Blood Cell Rheology
A small human trial found that combined omega-3 and omega-6 EFA supplementation improved red blood cell deformability and rheological properties, which may support microcirculation.
