美国FDA批准纤维蛋白原浓缩液上市RiaSTAP
 美国FDA批准CSL Behring公司的纤维蛋白原浓缩液（fibrinogen concentrate，RiaSTAP）上市，首个和迄今唯一用于治疗先天性纤维蛋白原缺陷（包括纤维蛋白原缺乏血症和低纤维蛋白原血症）患者的急性出血。罕见先天性纤维蛋白原缺乏，但此潜在威胁生命的出血疾病影响约百万分之一的人。本品不适用于异常纤维蛋白原血症。 
2008年3月，本品获准进入罕用阶段，2008年8月进行了优先评价。本品获准上市是基于一项关键的前瞻性开放式II期临床采用最大血块硬度（MCF）作为凝血疗效替代终点进行了药动学和安全性研究。MCF是血块结构完整性的实验室测定，反映了纤维蛋白原形成纤维蛋白血块的潜在效果。 
 纤维蛋白原也称为凝血因子I，是形成血块所需蛋白质。血浆中纤维蛋白原浓度决定了形成血块的能力和在体内的活性。纤维蛋白原浓度降低限制了体内形成血块的能力。 
本品是经确保安全的病毒灭活和去除纯化的纤维蛋白原浓缩液。在全球销售100万单位（美国外的商品名为Haemocomlettan）。 
对15例患者药动学研究显示，平均纤维蛋白原血浆抗原浓度和平均血浆活性水平分别在输注后30分钟至1小时达到最大程度，随后逐渐降低。结果还表明，输注本品1小时后平均改善 MCF的效果较基础值显著高（P<0.000 1）。

RiaSTAP获孤儿药地位
CSL Behring的先天性纤维蛋白原缺乏病治疗药RiaSTAP获得美国FDA批准上市，这还是FDA批准的第一个该类疾病治疗药，公司将获得7年的市场独占期。

What is RiaSTAP?
RiaSTAP is a man-made form of a protein that occurs naturally in the body and helps the blood clot.

RiaSTAP is used to treat bleeding episodes in people who have a congenital fibrinogen deficiency.

RiaSTAP may also be used for other purposes not listed in this medication guide.

Important information about RiaSTAP
You should not use RiaSTAP if you have ever had an allergic reaction to fibrinogen, or if you have ever had any life-threatening allergic reaction.

If you have certain conditions, you may need a dose adjustment or special tests to safely use this medication. Before using RiaSTAP, tell your doctor if you have a history of stroke or blood clot.

Do not self-inject RiaSTAP if you do not fully understand how to give the injection and properly dispose of needles, IV tubing, and other items used in giving the medicine. RiaSTAP comes with patient instructions for safe and effective use. Follow these directions carefully. Ask your doctor or pharmacist if you have any questions.

If you are using the RiaSTAP injections at home, be sure you understand how to properly mix and store the medication. Do not mix the medicine until you are ready to give the injection.

Stop your IV infusion and get emergency medical help if you have any of these signs of an allergic reaction: hives; wheezing or difficult breathing; feeling like you might pass out; or swelling of your face, lips, tongue, or throat.

Other serious side effects may include sudden numbness or weakness, chest pain, confusion, pain or swelling in your one or both legs, and problems with vision, speech, or balance.

RiaSTAP is made from human plasma (part of the blood) and may contain viruses and other infectious agents that can cause disease. Although donated human plasma is screened, tested, and treated to reduce the risk of it containing anything that could cause disease, there is still a small possibility it could transmit disease. Talk with your doctor about the risks and benefits of using this medication.

How should I use RiaSTAP?
RiaSTAP is given as an injection through a needle placed into a vein. Your doctor, nurse, or other healthcare provider will give you this injection. You may be shown how to use your medicine at home. Do not self-inject RiaSTAP if you do not fully understand how to give the injection and properly dispose of needles, IV tubing, and other items used in giving the medicine.

You will need to mix RiaSTAP with a liquid (diluent) before using it. If you are using the injections at home, be sure you understand how to properly mix and store the medication. Do not mix RiaSTAP with any other medicines, or give other medicines through the same IV line.

RiaSTAP contains no preservative. Once you have pierced the rubber top of a vial with a needle, you must use that vial right away or throw it away. Do not shake the medication vial (bottle). Vigorous shaking can ruin the medicine. Do not draw your RiaSTAP dose into a syringe until you are ready to give yourself an injection. Do not use the medication if it has changed colors or has any particles in it. After mixing RiaSTAP with a diluent, use it right away or store the mixture at room temperature and use it within 24 hours. The mixed medicine should be clear or slightly colored. Do not use the mixed medication if it has changed colors, is cloudy, or has any particles in it.

Each single-use vial (bottle) of this medicine is for one use only. Throw away the vial after one use, even if there is still some medicine left in it after injecting your dose.

To be sure RiaSTAP is helping your condition, your blood may need to be tested often. This will help your doctor determine how long to treat you with RiaSTAP. Do not miss any follow-up visits to your doctor.

Use each disposable needle only one time. Throw away used needles in a puncture-proof container (ask your pharmacist where you can get one and how to dispose of it). Keep this container out of the reach of children and pets.

Store the unmixed dry powder in a refrigerator or in a dark cool place. Keep the medicine protected from light and do not allow it to freeze. Throw away any unused vial after the expiration date on the label has passed.

What happens if I miss a dose?
Use the missed dose as soon as you remember. If it is almost time for your next dose, wait until then to use the medicine and skip the missed dose. Do not use extra medicine to make up the missed dose.

What happens if I overdose?
Seek emergency medical attention if you think you have used too much of this medicine.

Symptoms of a RiaSTAP overdose are not known.

What should I avoid while taking RiaSTAP?
Follow your doctor's instructions about any restrictions on food, beverages, or activity while you are using RiaSTAP.
