This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. Acute Intermittemt Porphozym is caused by an inherited defect of the enzyme porphobilinogen deaminase (PBGD), the third enzyme in the biosynthetic pathway leading to heme. The new treatment, which has been made in a biological laboratory by modern methods of molecular biology, is a preparation of this enzyme, rhPBGD, Porphozym¿. The purpose of the trial is to compare the efficacy and safety of Porphozym¿ with that of placebo as a treatment of AIP in subjects with acute attacks. The placebo is an inactive material identical in appearance to the drug undergoing testing. The Danish/Swedish company, HemeBiotech A/S, will supply both Porphozym¿ and placebo. After coming to the hospital with an acute attack, and signing the study consent form, you will be given treatment with either Porphozym¿ or placebo. You will be assigned to a treatment based on a pre-determined order decided at random (like flipping a coin). Therefore you will have a 50% chance of receiving the new treatment. Neither your doctor nor you will know which treatment you will receive. Treatment will be given into a blood vessel (a vein) over a period of 48 hours. You will be followed until you are discharged from the hospital. 14 days and 28 days after end of treatment you will come to the outpatient clinic for a follow-up visit. If you do not experience a new attack before the last of these visits, you will be followed until your next attack or for 6 months, whichever comes first.

本子项目是利用由NIH/NCRR资助的中心赠款提供的资源的众多研究子项目之一。子项目和研究者（PI）可能已经从另一个NIH来源获得了主要资金，因此可以在其他CRISP条目中表示。列出的机构是中心的，不一定是研究者的机构。急性间歇性卟啉酶是由卟啉胆色素原脱氨酶（PBGD）的遗传缺陷引起的，这是生物合成途径中导致血红素的第三种酶。这种新的治疗方法是用现代分子生物学方法在生物实验室中制备的，它是一种酶，rhPBGD, Porphozym¿。该试验的目的是比较Porphozym¿与安慰剂治疗急性发作AIP的疗效和安全性。安慰剂是一种非活性物质，在外观上与接受测试的药物相同。丹麦/瑞典公司HemeBiotech A/S将同时提供Porphozym和安慰剂。在您因急性发作来到医院并签署研究同意书后，您将接受Porphozym或安慰剂的治疗。你将被分配到一个基于预先确定的顺序随机决定的治疗（就像抛硬币一样）。因此，你将有50%的机会接受新的治疗。你的医生和你都不知道你会接受哪种治疗。治疗将在48小时内进入血管（静脉）。你将被跟踪直到出院。治疗结束后14天和28天，您将到门诊进行随访。如果您在最后一次访问之前没有经历新的攻击，您将被跟踪直到您的下一次攻击或6个月，以先到者为准。
