Coversin in PNH in Patients With Resistance to Eculizumab Due to Complement C5 Polymorphisms (CONSENTII)
February 7, 2024 updated by: AKARI Therapeutics
CONSENT II: Coversin in Paroxysmal Nocturnal Hemoglobinuria (PNH) in Patients With Resistance to Eculizumab Due to Complement C5 Polymorphisms
Coversin in Paroxysmal Nocturnal Hemoglobinuria (PNH) in patients with resistance to Eculizumab due to complement C5 polymorphisms.

Intervention / Treatment
Detailed Description
Coversin, a small protein complement C5 inhibitor which prevents the cleavage of C5 by C5 convertase into C5a and C5b, will be used in an open label, non-comparative clinical trial in patients with PNH and proven resistance to eculizumab due to C5 polymorphisms.
Patients will be treated with Coversin by daily subcutaneous injection for 6 months in order to determine the safety and efficacy of the drug in these circumstances.
If satisfactory control of the PNH is achieved, and at the discretion of the Principal Investigator (PI), patients will have the option of remaining on Coversin and being entered into the long term follow-up study.

Change in score on Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) questionnaire
Time Frame: Baseline to Day 180
|
The FACIT Measurement System is a collection of quality of life questionnaires targeted to the management of chronic illness.
Change in FACIT-F score, measured on a scale from 0 - 4 (0 = Not at all, 1 = A little bit, 2 = Some-what, 3 = Quite a bit, 4 = Very much).

Baseline to Day 180
|
Change in EuroQol 5 Dimensional 5 Level (EQ-5D-5L) score
Time Frame: Baseline to Day 180
|
The descriptive questionnaire comprises of five sections: Mobility, self-care, usual activities, pain/discomfort and anxiety/depression.
Each section has 5 levels: No problems, slight problems, moderate problems, severe problems and extreme problems.
The patient is asked to indicate his/her health state by ticking the box next to the most appropriate statement in each of the five dimensions.
This decision results in a 1-digit number that expresses the level selected for that section.
The digits for the five sections can be combined into a 5-digit number that describes the patient's health state.
