Study summary

This is a multicenter, open-label study to evaluate the long-term safety and efficacy of XH-S003 capsules in PNH patients. About 26 PNH patients who had received and completed XH-S003 study treatment will be enrolled to take XH-S003 capsules orally according to protocol. Eligible subjects can maintain XH-S003 treatment until the end of the study.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  1. PNH patients who have previously received and completed the XH-S003 study treatment, and according to the investigator's evaluation, the benefits of treatment outweigh risks and may benefit from continued treatment with XH-S003;
  2. Subjects who have been vaccinated against Neisseria meningitidis and Streptococcus pneumoniae as required by previous studies (if the vaccine protection period does not cover the duration of this study, timely booster vaccinations should be administered according to vaccination guidelines and local vaccination requirements);

Exclusion criteria

Exclusion Criteria:

  1. . History of in any organ or system within the past 5 years prior to screening (excluding localized basal cell carcinoma of the skin or in situ cervical cancer);
  2. History of bone marrow/hematopoietic stem cell or solid organ transplantation;
  3. History of splenectomy;
  4. History of serious comorbidities , including but not limited to: advanced stage heart disease (e.g., [NYHA] Class IV), severe lung disease (e.g., severe pulmonary hypertension [WHO Class IV]), severe liver function injury, severe renal disease (estimated [eGFR] \< 30 mL/min/1.73 m2 or chronic kidney disease [CKD] Stage 4 or dialysis patients), unstable thrombus, other hematologic system diseases (e.g., chronic anemia unrelated to PNH), and deemed unsuitable for study participation by the investigator;
  5. Pregnant or lactating women, or those with a positive pregnancy test;
  6. Known or suspected immunodeficiency diseases or hereditary complement deficiency at screening;
  7. A history of Neisseria meningitidis infection
Terms in these criteria, in plain language(3)

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.

Cancer (malignancy)

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.

NYHA class (heart failure)

The New York Heart Association’s four classes of how much heart failure limits physical activity.

I
No limits: ordinary activity causes no undue tiredness or breathlessness.
II
Slight limits: comfortable at rest, ordinary activity causes symptoms.
III
Marked limits: comfortable at rest, less than ordinary activity causes symptoms.
IV
Symptoms even at rest; any activity makes them worse.

Studies set their own limit — many outside heart failure leave out class III–IV, while heart failure studies may ask for a particular class. Check the class this study names.

GFR and eGFR (kidney filtering)

GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².

Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
