Replicor announces publication of the REP 401 study achieving high rates of virologic control and functional cure in patients with chronic hepatitis B infection

MONTREAL, March 9, 2020 – Replicor Inc., a privately held biopharmaceutical company targeting functional cure for patients with chronic hepatitis B and D infection, announced the publication of the final results of its latest REP 401 study in the prestigious journal Gastroenterology.

The article, entitled “Safety and Efficacy of 48 Weeks REP 2139 or REP 2165, Tenofovir Disoproxil, and Pegylated Interferon Alfa-2a in Patients With Chronic HBV Infection Naïve to Nucleos(t)ide Therapy”, presents the analysis of the safety and efficacy of NAP therapy when added to a backbone of TDF and pegIFN in patients with treatment naïve chronic HBV infection.

The culmination of more than a decade of clinical investigation of NAPs, transitioning from REP 2055 to REP 2139-Mg, the REP 401 study achieved dramatic increases in the incidence of HBsAg loss and seroconversion during therapy (60%) and therapeutic transaminase flares (95%) compared to that observed with TDF + pegIFN alone.  Importantly 78% of participants achieved virologic control of HBV of whom 39% further achieved functional cure.  These outcomes dramatically improve those achieved by TDF + pegIFN alone and far exceed those observed with any other therapy currently in development in mono or combination therapy.

Dr. Andrew Vaillant, CSO of Replicor commented, “Our substantial body of published data clearly demonstrates that all NAPs using Replicor’s proprietary poly AC technology have very similar activity with similar doses required in humans.  However, only NAPs formulated as magnesium chelate complexes such as REP 2139-Mg and REP 2165-Mg have the excellent tolerability and safety required for use with immunotherapy.  This combination approach is essential to awaken an effective immune response capable of driving high rates of therapeutic transaminase flares essential for restoring virologic control and functional cure.  The successful completion of the REP 401 study paves the way for the long-planned transition of REP 2139-Mg to subcutaneous administration and assessment in combination with other immunotherapies capable of driving HBsAg specific T-cell activation, an activity we believe is a critical component of achieving functional cure.”

Replicor宣布发表REP 401研究报告,该研究在慢性乙型肝炎患者中实现了较高的病毒学控制和功能治愈

蒙特利尔,2020年3月9日–一家私有生物制药公司Replicor Inc.,其针对慢性乙型和丁型肝炎感染患者的功能性治疗,已在享有盛誉的《胃肠病学》杂志上宣布了其最新REP 401研究的最终结果。

文章标题为“ 48周REP 2139或REP 2165,替诺福韦二吡咯烷和聚乙二醇化干扰素Alfa-2a在未接受过核仁(t)治疗的慢性HBV感染患者中的安全性和有效性”,对安全性和有效性进行了分析初治慢性HBV感染患者中,当将NAP治疗加到TDF和pegIFN的骨架中时。

从REP 2055到REP 2139-Mg的NAP临床研究十多年的巅峰时期,REP 401研究使治疗期间HBsAg丢失和血清转化的发生率显着增加(60%),并且治疗性转氨酶耀斑(95) %)与仅使用TDF + pegIFN观察到的相比。重要的是,78%的参与者实现了HBV的病毒学控制,其中39%的参与者进一步实现了功能治愈。这些结果大大改善了仅通过TDF + pegIFN实现的结果,远远超过了目前在单一或联合治疗中开发的任何其他治疗方法所观察到的结果。

Replicor的CSO Andrew Vaillant博士评论说:“我们大量的公开数据清楚地表明,所有使用Replicor专有的聚AC技术的NAP的活性与人体所需的剂量相似,但非常相似。但是,只有配制成镁螯合复合物的NAP,例如REP 2139-Mg和REP 2165-Mg具有出色的耐受性和安全性,可与免疫疗法配合使用,这种组合方法对于唤醒有效的免疫反应至关重要,该免疫反应能够引发高剂量的治疗性转氨酶耀斑,对于恢复病毒学控制和功能性治愈至关重要。 REP 401研究的成功完成为REP 2139-Mg长期计划过渡到皮下给药和评估铺平了道路,并与其他能够驱动HBsAg特异性T细胞活化的免疫疗法相结合,我们认为这是至关重要的一项活动达到功能性治愈的目的。”

78%中(总数中),其中39%。那就是78乘于39除以10000大概是32%总数,全部转阴,这个和长效+核苷3o%的总治愈率一样,他是玩数字游戏而已

其实核苷+干扰素也很好的治疗方案,可以达到30%左右的功能治愈,但是他入组有条件的,例如小于HBsa;1500单位,而且费用太高,每月将近3600元,一个年疗程需要40000-50000元钱(加上检查万费用’

    Correction to: Hepatitis B Surface Antigen Loss with Tenofovir Disoproxil Fumarate Plus Peginterferon Alfa-2a: Week 120 Analysis. [Dig Dis Sci. 2019]

Abstract
BACKGROUND AND AIMS:

Hepatitis B surface antigen (HBsAg) loss is the ideal clinical endpoint but is achieved rarely during oral antiviral treatment. A current unmet need in CHB management is achievement of HBsAg loss with a finite course of oral antiviral therapy, thereby allowing discontinuation of treatment. Significantly higher rates of HBsAg loss at 72 weeks post-treatment have been demonstrated when tenofovir disoproxil fumarate (TDF) was combined with pegylated interferon (PEG-IFN) for 48 weeks compared with either monotherapy. This analysis provides follow-up data at week 120.
METHODS:

In an open-label, active-controlled study, 740 patients with chronic hepatitis B were randomly assigned to receive TDF plus PEG-IFN for 48 weeks (group A), TDF plus PEG-IFN for 16 weeks followed by TDF for 32 weeks (group B), TDF for 120 weeks (group C), or PEG-IFN for 48 weeks (group D). Efficacy and safety at week 120 were assessed.
RESULTS:

Rates of HBsAg loss at week 120 were significantly higher in group A (10.4%) than in group B (3.5%), group C (0%), and group D (3.5%). Rates of HBsAg loss and HBsAg seroconversion in group A were significantly higher than rates in group C (P < 0.001 for both) or group D (HBsAg loss: P = 0.002; HBsAg seroconversion: P < 0.001).
CONCLUSIONS:

The results of this analysis confirm the results from earlier time points which demonstrate the increased rate of HBsAg loss in patients treated with a finite course of PEG-IFN plus TDF compared with the rates in patients receiving either monotherapy.

抽象
背景与目的:

乙型肝炎表面抗原(HBsAg)丢失是理想的临床终点,但在口服抗病毒治疗期间很少达到。 CHB管理中当前未满足的需求是通过有限的口服抗病毒治疗疗程实现HBsAg的流失,从而可以中止治疗。与任何一种单一疗法相比,当替诺福韦富马酸替诺福韦(TDF)与聚乙二醇干扰素(PEG-IFN)联合治疗48周时,治疗后72周的HBsAg丢失率显着提高。该分析提供了第120周的随访数据。
方法:

在一项开放标签,主动对照研究中,将740名慢性乙型肝炎患者随机分配接受TDF + PEG-IFN治疗48周(A组),TDF + PEG-IFN治疗16周,然后接受TDF 32周( B组),TDF 120周(C组)或PEG-IFN 48周(D组)。在第120周时评估疗效和安全性。
结果:

A组(10.4%)在第120周的HBsAg丢失率显着高于B组(3.5%),C组(0%)和D组(3.5%)。 A组的HBsAg丧失和HBsAg血清转化率显着高于C组(两者均P << 0.001)或D组(HBsAg丧失:P = 0.002; HBsAg血清转化:P <0.001)。
结论:

该分析的结果证实了较早时间点的结果,这些结果表明,接受有限疗程的PEG-IFN加TDF治疗的患者与接受任一单一疗法的患者相比,HBsAg丢失率增加。

这个药虽然报道的效果还行,但真实性让人怀疑。

之前这家公司在官网pipeline写了欧洲、美洲具体的推进时间,就在2020年。结果后面全变成in planning stage了。对其实验真实性表示怀疑。
