TREATMENT OF CHRONIC HEPATITIS B INFECTION WITH DV-601, A THERAPEUTIC VACCINE

Therapeutic vaccines may promote the resolution of chronic hepatitis B infection (CHB) through the stimulation of specific cytotoxic T-lymphocyte and B-cell antibody responses to dominant hepatitis B virus (HBV)-antigens. DV-601 is comprised of recombinant HBV surface antigen (HBsAg) and HBV core antigen (HBcAg), with adjuvant. In this initial dose-escalation study of DV-601 in treatment-naïve or treatment-tolerant adult patients with CHB, patients received 6 intramuscular doses of DV-601 (0.1, 0.25, or 0.5 mL) on Days 1, 15, 29, 57, 71, and 85. Of the 14 enrolled patients, 8 were HBV e-antigen positive and were treatment-naïve; 6 patients, all HBV e-antigen negative, had been treated with nucleoside analog(s) prior to enrolling in the study. Oral entecavir therapy was initiated (and other nucleoside analog therapy was discontinued, if applicable) prior to the first DV-601 injection, and was continued daily during the study. The primary objective was to assess the safety and tolerability of DV-601 by the evaluation of local and systemic adverse events to Day 99, including changes in laboratory analyses. Secondary objectives were to evaluate virological response and immunogenicity of DV-601 based on HBV viral load, and humoral and T cell immunological responses. Fourteen patients were enrolled and completed all injections of DV-601. Injection site reactions were generally short-lived and resolved without treatment; systemic injection reactions including fatigue, malaise, chills, and headache were transient and rarely required intervention. Reductions in HBV DNA, and s and e antigen are apparent in all dose groups, and antibodies to s and e antigens developed in the higher dose groups. All patients developed an HBV-specific lymphoproliferative response; an HBc-specific interferon-gamma T cell response was noted in 2 of 6 patients who were e-antigen positive and had received the highest dose of DV-601. DV-601 appears to be a safe and well-tolerated therapeutic vaccine for the treatment of CHB, and virological response is evident.

目前看不到具体的数据,但是可以看出,DV-601的耐受性不错,HBV dna 下降,在高剂量组中已经观察到s和e抗体的产生。
不管怎么说,总归看到了点希望

你没有仔细看过置顶的王主任的拉米攻略,王主任除干扰素不爱用外(10多年前爱用),阿德、恩替等核苷药物都用,用的最多的是拉米。
很多人骂王主任只用拉米,其实是他们自己不长眼,不看原帖,人云亦云。

如果你看过王主任的帖子,只能说你是一个实实在在的SB,完全看不懂王主任的话。

如果你不是一个SB,你就是为了推销你主子的药出来乱咬。

其实你既是一个SB又是一个卖力推销你主子药的疯狗。

拉米已经不是一线用药,无谓的谩骂只能表现一个人的无知和粗俗。
王震宇的治疗路线图有一定的道理,但是,和主流的认识存在一定的差异。

既然替诺福韦和恩替卡韦都已经出来,犯不着去用拉米,成天提心吊胆的担心耐药。
你倒是说说,用恩替卡韦和替诺福韦那点比拉米差?
用实验数据说话啊!

不要动不动就说别人是SB。

你比SB要强那么一点。你能认识到主流的观点,不过你要接受先进的观点还需要一些时间。
你想看到的最好数据王震宇主任已经发表,遗憾的是要看懂这些数据和王震宇主任背后的理念,你还差那么一点点。你和那些SB不同,那些垃圾为了推销他们主子的昂贵药物,他们或者不能看懂王主任的数据或者不愿意看懂。
你再加把劲!

现在所有的 核苷类药 基本是稳定病情。。。 说白了 就是   拖   拖到死 的理论(当然也有拖到好的呵呵)    如果是这样子 为何不选 拉米   目前全世界公认 最多临床病例经验,最安全,较便宜 的药 。 耐药了再换其它药我看有什么不对的?即然是拖,从经济从便宜吃到贵,正常啊!  很多现在的医师都喜欢 治疗初期用 干扰。  像那个什么 XX欣的  一针就 1000多 一个月大约5000,贵的离谱,而且还要赌,劳命伤财啊。 真的是何必呢。  还不如用上核苷类药 成本低, 拖那么几年几十年,新药就出来了,达到的目的都是一样的, 。。。 离题了 。。。end.

Dynavax Reports Additional Positive Phase 1B Immunogenicity Data for Hepatitis B Therapy Candidate
BERKELEY, CA--(Marketwire - February 22, 2011) - Dynavax Technologies Corporation (NASDAQ: DVAX) reported in a poster session Saturday, February 19 at the 21st Conference of the Asian Pacific Association for the Study of the Liver (APASL 2011) in Bangkok, Thailand new Phase 1b immunogenicity data for DV-601, its proprietary hepatitis B therapeutic vaccine. The study evaluated three doses of the candidate therapeutic vaccine escalation in 14 patients with chronic hepatitis B infection, including six patients that were HBeAg negative and eight patients who were HBeAg positive, and found:

The therapeutic regimen was safe and generally well tolerated at all dose levels;
Most common systemic reactions were fatigue and malaise. No SAEs were recorded;
DV601 was found to elicit immune responses at all dose levels, and anti-HBe antibodies were elicited in two of eight (2/8) patients;
Anti-HBs antibodies were elicited in four of 14 (4/14) patients;
Amongst the eight HBeAg positive patients, two had HBeAg clearance, and one of those individuals also had HBsAg clearance;  
Three patients are still in the follow-up observation period.
According to Tyler Martin, M.D., President and Chief Medical Officer, "This trial was primarily designed to assess the safety of our vaccine. The positive immunogenicity results, in particular, the two HBeAg seroconversions, including one HBsAg serocoversion, provide a strong rationale for an expanded evaluation of our approach in collaboration with a potential partner."

Dynavax in December 2010 reported that all doses were generally safe and well tolerated and that individual immunologic and virologic responses had been observed across cohorts at all dose levels.

Dynavax's treatment approach combines both the surface and core hepatitis B virus (HBV) antigens with ISCOMATRIX® adjuvant originally entered into development by Rhein Biotech prior to its acquisition by Dynavax in 2006. The candidate vaccine, DV-601, is designed to induce an immune response against HBV-infected cells and if proven to be safe and effective, may offer an alternative therapeutic option for patients chronically infected with HBV.

Dear ybdn,你好,其实咱们还是在讨论问题,没必要这么动肝火。
对事不对人才,不要让论坛的事情影响了你的心情,甚至你现实中的生活。
