Among the 51 studies in Hemoglobinuria, Paroxysmal with a site in China, from their registry updates:
The main purpose of this study is to evaluate the efficacy of MY008211A in PNH patients with residual anemia despite treatment with anti-C5 antibody.
This is a multicenter, single-arm, open-label phase III clinical trial. The purpose of this study is to determine whether MY008211A is efficacious and safe for the treatment of PNH patients Who Are Still Anemia After Anti-C5 Antibody Treatment.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.
The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).
Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Change in FACIT-F score from baseline
Change in FACIT-Fatigue score from baseline. The FACIT-Fatigue is a 13-item questionnaire with support for its validity and reliability in PNH that assesses patient self-reported fatigue and its impact on daily activities and function. All FACIT scales are scored so that a high score is better. As each of the 13 items of the FACIT-F Scale ranges from 0-4, the range of possible scores is 0-52, with 0 being the worst possible score and 52 the best.

Started Aug 2024 (actual). Primary completion is estimated for Dec 2025, 16 months after the start.
Of 35 industry-sponsored phase 3 interventional studies under Hemoglobinuria, Paroxysmal, half reached primary completion within 23 months of starting (the median), counting those still running; a quarter within 15 and three quarters within 41. This study's planned 16 months is below that.
Counting every sponsor, half of 35 studies reached it within 23 months; a quarter within 15 and three quarters within 41.
