Patients With Paroxysmal Nocturnal Hemoglobinuria (PNH) | Drug: LNP023 | Phase 2 |
LNP023 is a novel oral small molecular weight compound, that inhibits alternative complement pathway (AP). Blockade of the AP with oral LNP023 has the potential to prevent both intra - and extravascular hemolysis.
This study includes a screening period of up to 68 days, a baseline visit, up to approximately 3 years of treatment with LNP023 administered in addition to SoC, and an End of Study (EoS) visit 2 weeks after last LNP023 administration.
The main purpose of this study is to evaluate the efficacy of LNP023 in patients with PNH, showing signs of active hemolysis despite treatment with SoC (defined as an antibody with anti C5 activity).

Ages Eligible for Study: | 18 Years to 80 Years (Adult, Older Adult) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
Inclusion Criteria:
- Written informed consent must be obtained before any assessment is performed.
- Male and female patients between the age of 18-80 (inclusive) at baseline with a diagnosis of PNH based on documented clone size of ≥10% by RBCs and/or granulocytes, measured by GPI-deficiency on flow cytometry (screening or medical history data acceptable).
