LOWR HDV Studies:

    LOWR HDV – 2 is a dose-finding study to identify optimal combination regimens of lonafarnib and ritonavir + PEG-IFN-α, with efficacy and tolerability for longer term dosing to enable HDV RNA clearance.  In this open-label study, approximately 40 HDV infected patients have been enrolled to date into 9 groups of different doses of lonafarnib in combination with ritonavir for dosing durations of 12 or 24 weeks. Lonafarnib doses range from 100 mg bid to 25 mg bid.  LOWR HDV – 2 is being conducted at Ankara University in Ankara, Turkey.
    LOWR HDV – 3 is a double-blinded, randomized, placebo-controlled study designed to evaluate the efficacy and tolerability of once-daily doses of lonafarnib – 50 mg, 75 mg and 100 mg – each combined with ritonavir 100 mg once daily for 12 or 24 weeks.  Twenty-one patients with chronic hepatitis delta were randomized into one of six treatment groups.  LOWR HDV – 3 is being conducted at the National Institutes of Health (NIH) Clinical Center in Bethesda, Maryland and dosing has been completed.
    LOWR HDV – 4 is an open-label study to evaluate the efficacy and tolerability of dose escalation of lonafarnib combined with ritonavir administered twice daily for dosing durations of 24 weeks. Fifteen patients were initiated at lonafarnib 50 mg and ritonavir 100 mg twice daily, and dose-escalated up to lonafarnib 100 mg twice daily at the discretion of the investigator. LOWR HDV – 4 is being conducted at Hannover Medical School in Hannover, Germany and dosing has been completed.

About Sarasar™ (lonafarnib)

Lonafarnib is a well-characterized, late-stage, orally active inhibitor of farnesyl transferase, an enzyme involved in modification of proteins through a process called prenylation.  HDV uses this host cell process inside liver cells to complete a key step in its life cycle. Lonafarnib inhibits the prenylation step of HDV replication inside liver cells and blocks the virus life cycle at the stage of assembly.  Since prenylation is carried out by a host enzyme, treatment with lonafarnib may present a higher barrier to development of viral resistance mutations. Lonafarnib has been dosed in over 100 HDV-infected patients across international academic centers and is in Phase 2 development for HDV. Lonafarnib has been granted Orphan Drug Designation by the U.S. Food and Drug Administration (FDA) and European Medicines Agency (EMA), and Fast Track Designation by U.S. FDA. Lonafarnib is not approved for any indication, and is licensed from Merck Sharp & Dohme Corp. (known as MSD outside of the United States and Canada).

About Hepatitis Delta Virus (HDV)

Hepatitis Delta (or Hepatitis D) is caused by infection with HDV and is considered to be one of the most severe forms of viral hepatitis in humans. Hepatitis delta occurs only as a co-infection in individuals harboring Hepatitis B Virus (HBV). Hepatitis delta leads to more severe liver disease than HBV alone and is associated with accelerated liver fibrosis, liver cancer, and liver failure. Hepatitis delta is a disease with a significant impact on global health, which may affect up to approximately 15-20 million people worldwide. The prevalence of HDV varies among different parts of the world.  Globally, HDV infection is reported to be present in approximately 4.3% to 5.7% of chronic Hepatitis B carriers. The prevalence of HDV in patients infected with chronic HBV is even higher in certain regions, including certain parts of Mongolia, China, Russia, Central Asia, Pakistan, Turkey, Africa, and South America, with an HDV prevalence as high as 60% being reported in HBV-infected patients in Mongolia and Pakistan.

LOWR HDV研究:

    LOWR HDV-2是一种剂量研究,用于鉴定洛那法尼和利托那韦+ PEG-IFN-α的最佳组合方案,具有长期给药以使HDV RNA清除的功效和耐受性。在这个开放标签研究中,约40个HDV感染的患者已登记到9组不同剂量的lonafarnib与利托那韦组合,给药持续时间为12或24周。 Lonafarnib剂量范围为100mg bid至25mg bid。 LOWR HDV-2正在土耳其安卡拉的安卡拉大学进行。
    LOWR HDV-3是一项双盲,随机,安慰剂对照研究,旨在评价每日一次剂量的洛那法尼50mg,75mg和100mg的效力和耐受性,每种联合利托那韦100mg每日一次,共12次或24周。 21例慢性戊型肝炎患者随机分为6个治疗组。 LOWR HDV-3正在马里兰州贝塞斯达的国家卫生研究院(NIH)临床中心进行,并且已经完成了给药。
    LOWR HDV-4是开放标签研究,用于评价与利托那韦联合的洛那法尼的剂量递增的效力和耐受性,每天两次,给药时间为24周。 15名患者由洛拉法尼50 mg和利托那韦100 mg每日两次开始,剂量逐步升高至lonafarnib 100 mg,每日两次,由研究者决定。 LOWR HDV-4正在德国汉诺威的汉诺威医学院进行,剂量已经完成。

关于Sarasar™(lonafarnib)

Lonafarnib是一种良好表征的,晚期,口服有效的法呢基转移酶抑制剂,一种参与通过称为异戊烯化的过程修饰蛋白质的酶。 HDV使用肝细胞内的这种宿主细胞过程来完成其生命周期中的关键步骤。 Lonafarnib抑制肝细胞内HDV复制的异戊烯化步骤,并在组装阶段阻断病毒生命周期。由于异戊二烯化是通过宿主酶进行的,所以用lonafarnib处理可以对病毒抗性突变的发展提供更高的屏障。 Lonafarnib已经在跨越国际学术中心的超过100个HDV感染的患者中给药,并且在HDV的第2期发展中。 Lonafarnib已经被美国食品和药物管理局(FDA)和欧洲药品管理局(EMA)授予孤儿药物指定,并由美国FDA授予快速通道指定。 Lonafarnib未获批准用于任何适应症,并获得Merck Sharp&Dohme公司(在美国和加拿大境外称为MSD)的许可。

关于丙型肝炎病毒(HDV)

甲型肝炎(或戊型肝炎)是由HDV感染引起的,被认为是人类最严重的病毒性肝炎之一。甲型肝炎仅发生在携带乙型肝炎病毒(HBV)的个体中作为共感染。丁型肝炎导致比单独的HBV更严重的肝病,并且与加速的肝纤维化,肝癌和肝衰竭有关。丁型肝炎是一种对全球健康有重大影响的疾病,可能影响全世界约1500万至2000万人。 HDV的患病率在世界不同地区不同。在全球,据报道HDV感染存在于约4.3%至5.7%的慢性乙型肝炎携带者中。在包括蒙古,中国,俄罗斯,中亚,巴基斯坦,土耳其,非洲和南美洲的某些地区的HDV患病率高达60%的某些地区,HDV在患有慢性HBV的患者中的患病率甚至更高报道在蒙古和巴基斯坦的HBV感染患者。
