دراسة لتقييم مدى أمان العلاج المركب بوزيليماب + سيمديسيران ومدى فعاليته في المرضى البالغين الذين يعانون من الهيموغلوبينية الليلية الانتيابية (PNH) والذين لم يتلقوا مؤخرًا أو لم يتلقوا علاجًا بمثبطات المكملات
This research study is investigating a new combination of two medications, pozelimab and cemdisiran, for adults living with a rare blood disorder called Paroxysmal Nocturnal Hemoglobinuria (PNH). The main goals are to find out how safe this new combination is and how well it works. We're also comparing its effects to two established PNH treatments, ravulizumab and eculizumab. Participants are adults who haven't recently received or have never had treatment with complement inhibitor medicines for their PNH. The study will help us understand side effects, how the body handles these new drugs, and whether the body might make antibodies against them, which could affect their usefulness.
نظرة سريعة
ما هو موضوع هذه الدراسة؟
This study is exploring potential new treatments for a rare blood condition called Paroxysmal Nocturnal Hemoglobinuria, often shortened to PNH. PNH causes red blood cells to break down too early, leading to symptoms like tiredness, anaemia, and sometimes blood clots. Currently, there are treatments available, but researchers are always looking for new and potentially better options.
This particular study is focusing on a new combination of two experimental drugs called pozelimab and cemdisiran. The main purpose is to see how safe this combination is for people with PNH and how effectively it helps manage their condition. To understand its benefits, the study will compare this new combination with two existing and commonly used PNH treatments: ravulizumab and eculizumab.
By comparing these treatments, the study aims to answer important questions. We want to know if the new pozelimab and cemdisiran combination is as good as, or even better than, the current treatments. Researchers will also be carefully monitoring for any side effects and learning how the body processes these new medications. This helps us understand if the new treatment could be a valuable option for future PNH patients.
النقاط الرئيسية
- This study investigates a new combination treatment for PNH.
- It compares new drugs (pozelimab + cemdisiran) with existing PNH treatments.
- Safety and effectiveness for adults with PNH are key goals.
- تشمل المشاركة زيارات منتظمة للعيادة وفحوصات صحية.
- Meningitis vaccinations are a crucial eligibility requirement.
من قد يكون مؤهلاً؟
To join this study, you must be an adult (18 years or older) with PNH that has been officially diagnosed through special blood tests. Your PNH needs to be 'active,' meaning you're currently experiencing symptoms or signs of the condition, and certain blood levels (LDH level) must be above a specific point.
You also need to be able to attend all the study appointments, whether they are in person or online. It's very important that you are willing and able to get specific meningitis vaccinations, if you haven't had them already, as required by the study plan.
There are also reasons why you might not be able to join. For instance, if you've recently had certain PNH treatments (like eculizumab within the last 3 months, or ravulizumab within the last 6 months), or if you've had an organ or bone marrow transplant. You also can't participate if you weigh less than 40 kilograms, plan to use other PNH treatments not part of the study, or have certain infections.

أجب عن هذه الأسئلة السريعة لترى ما إذا كنت مؤهلاً. هذا دليل فقط - الفريق البحثي هو الذي يتخذ القرار النهائي.
- هل أنت بالغ (18 سنة أو أكثر)؟
- Have you been diagnosed with PNH?
- Are you experiencing active PNH symptoms or signs?
- Are you willing and able to get meningitis vaccinations if needed?
- Have you not recently received specific PNH complement inhibitor treatments (e.g., eculizumab in last 3 months, ravulizumab in last 6 months)?
- Have you NOT had an organ or bone marrow transplant?
ماذا يتضمن المشاركة؟
If you decide to take part in this study, you will likely receive either the new drug combination (pozelimab + cemdisiran) or one of the existing PNH treatments (ravulizumab or eculizumab). These will be given over a period of time as determined by the study. You will have regular visits, which might be in person at a clinic or sometimes done remotely. During these visits, the study team will carry out health checks, take blood samples to see how the treatment is working, and ask about any side effects you might be experiencing. They will also look at how much medication is in your blood and if your body is making antibodies against the study drugs. The total duration of your participation in the study, including follow-up, will be explained in detail by the study team.
