Measurement of serum lactate dehydrogenase (LDH)
LDH is an indicator of disease progression in patients with PNH and is expected to fall to within 2x upper limit of normal (ULN) within 28 days in successfully treated patients. Units are measured in ratio of LDH:ULN, where the ULN is 250 U/L. The primary efficacy endpoint was the LDH AUC from Day 0 to 28 compared with 28 days pretreatment. Data for the 28 days pre-treatment was not collected, and as only one patient was recruited, the LDH values compared with baseline and the ratio of LDH to the Upper Limit of Normal (ULN) are presented.
The number and type of reported AEs will be recorded as well as the opinion of the Principle Investigator (PI) as to their possible relationship to the study drug.

| Coversin treatment | EXPERIMENTAL | Coversin - 22.5mg followed by 45mg for 6 months. |
| Coversin (Nomacopan) | OTHER | This is an open label, non-comparator study. Patient will be given a single ablating dose of 0.57mg/kg per subject followed by daily repeat maintenance doses. The initial repeat dose will be 25% of the ablating dose. If this is insufficient to maintain complement inhibition at ≤10% of baseline (pre-treatment) level after 5 days of treatment the daily dose will be increased by doubling until that level of inhibition is achieved. In the event of 100% inhibition being achieved the dose may be titrated downwards at the PI's discretion until a satisfactory clinical result is obtained. If at any point in treatment complement inhibition falls to less than 50% of baseline a further ablating dose of 0.57mg/kg should be given. Coversin lyophilised powder in each vial was diluted with 0.6 mL water for injection prior to use. |

Coversin is an investigational small molecule being developed for Paroxysmal Nocturnal Haemoglobinuria (PNH), also known as Paroxysmal Nocturnal Hemoglobinuria. It is in Phase 2 clinical development for this hematologic condition. Coversin is not FDA approved and remains under investigation.
Coversin is being developed by Akari Therapeutics Plc, a biopharmaceutical company traded on the NASDAQ under the ticker AKTX. The company is conducting clinical trials to evaluate Coversin as a potential treatment for Paroxysmal Nocturnal Haemoglobinuria (PNH).
Coversin is in Phase 2 clinical development for Paroxysmal Nocturnal Haemoglobinuria (PNH). It is an investigational drug and has not received FDA approval. Clinical trials are ongoing to assess its safety and efficacy in this patient population.
Coversin has been studied in two completed Phase 2 clinical trials. The first, NCT02591862, evaluated Coversin in patients with Paroxysmal Nocturnal Haemoglobinuria (PNH) in the Netherlands. The second, NCT03427060, assessed Coversin in PNH patients with resistance to eculizumab due to complement C5 polymorphisms in the United States.
Coversin is being studied in patients with Paroxysmal Nocturnal Haemoglobinuria (PNH) who have resistance to eculizumab, a complement C5 inhibitor. The trials focus on patients with complement C5 polymorphisms, suggesting Coversin may target the complement system, though its specific molecular target is not detailed.
