一期效果怎么样

先前三项临床研究中 65 名受试者的结果表明,EB06 产生了解决与白癜风相关的功能失调的免疫反应所需的药效/生物活性,并且总体上是安全的且耐受性良好。 临床前研究还表明,CXCL10 的中和可以预防和逆转色素脱失。
具体的查不到,只有这个,他官网的报告

Edesa 的药物针对的是自身反应性 T 细胞,这些细胞会破坏表皮产生色素的细胞。 具体而言,EB06 与趋化因子配体 10 (CXCL10) 结合并抑制 CXCL10 与其受体的相互作用。  CXCL10在白癜风患者的皮肤和血清中均高表达,CXCL10与疾病的发生和白癜风病变的维持有关。 先前三项临床研究中 65 名受试者的结果表明,EB06 产生了解决与白癜风相关的功能失调的免疫反应所需的药效/生物活性,并且总体上是安全的且耐受性良好。 临床前研究还表明,CXCL10 的中和可以预防和逆转色素脱失。

Nijhawan 博士说:“我们相信,评估 EB06 预防和逆转白癜风明显症状的潜力具有重要的科学依据,我们对该计划改变人们生活的潜力感到兴奋。”

按照计划,加拿大卫生部批准的第 2 期研究方案将评估 EB06 与安慰剂相比,对中度至重度非节段性(全身性)白癜风成人患者的安全性和有效性。 患者将在治疗期间接受 EB06 或安慰剂的静脉输注,然后是随访期。 这项双盲、安慰剂对照研究将在加拿大多达约 25 个研究中心纳入约 120 名成年受试者。 主要终点将是面部白癜风面积评分指数 (F-VASI) 较基线的改善,这是一种定量临床工具,可估计白癜风斑块的总体面积以及这些斑块随时间推移的黄斑重新色素沉着程度。

可以求一下原文吗?感谢

Edesa Biotech Receives Regulatory Approval for Phase 2 Vitiligo Study
Published: Feb 01, 2023
Company's biologic drug candidate targets a key pathway involved in the progression and maintenance of depigmentation.
TORONTO, ON / ACCESSWIRE / February 1, 2023 /Edesa Biotech, Inc. (Nasdaq:EDSA), a clinical-stage biopharmaceutical company focused on inflammatory and immune-related diseases, today announced that it has received approval from Health Canada for a Phase 2 clinical study of the company's EB06 monoclonal antibody candidate as a treatment for vitiligo.

Vitiligo is a life-altering autoimmune disease that causes skin to lose its color in patches. While it can affect any area, vitiligo commonly occurs on the face, neck and hands, and is a lifelong condition. According to the World Health Organization, vitiligo affects approximately 1% of the world's population.

Par Nijhawan, MD, Chief Executive Officer of Edesa, said that the regulatory clearance of the study represents a key part of the company's development and partnership plans for EB06. "This significant milestone in our vitiligo program provides us another novel Phase 2-ready asset and the opportunity to expand our discussions around partnering and advancing this late-stage biologic asset in our pipeline. Despite the high prevalence of vitiligo, there are few effective treatment options and no approved systemic therapeutics targeting the underlying disease."

Edesa's drug targets autoreactive T cells that destroy the pigment-producing cells of the epidermis. Specifically, EB06 binds to chemokine ligand 10 (CXCL10) and inhibits the interaction of CXCL10 with its receptor(s). CXCL10 is highly expressed in vitiligo patients in both skin and serum, and CXCL10 is implicated in both the initiation of the disease and the maintenance of vitiligo lesions. Results from 65 subjects in three previous clinical studies demonstrated that EB06 produced the pharmacodynamic /biological activity required to address the dysfunctional immune response associated with vitiligo, and was generally safe and well tolerated. Preclinical studies have also demonstrated that neutralization of CXCL10 prevented and reversed depigmentation.

"We believe there is significant scientific rationale to evaluate EB06's potential to prevent and reverse the highly visible symptoms of vitiligo, and we are excited about the potential of this program to change people's lives," said Dr. Nijhawan.

As planned, the Phase 2 study protocol approved by Health Canada will evaluate the safety and efficacy of EB06 versus placebo in adults with moderate to severe non-segmental (generalized) vitiligo. Patients will receive intravenous infusions of either EB06 or placebo during the treatment period, followed by a follow-up period. Approximately 120 adult subjects will be included in the double-blind, placebo-controlled study at up to approximately 25 investigational centers in Canada. The primary endpoint will be improvement from baseline on the Face Vitiligo Area Scoring Index (F-VASI), a quantitative clinical tool that estimates the overall area of vitiligo patches and the degree of macular re-pigmentation within these patches over time.

Readers should not unduly rely on these forward-looking statements, which are not a guarantee of future performance. There can be no assurance that forward-looking statements will prove to be accurate, as all such forward-looking statements involve known and unknown risks, uncertainties and other factors which may cause actual results or future events to differ materially from the forward-looking statements.

我记得,他说有文章说cxcl10不靠谱,我没见过那文章。如果cxcl10是错的,安立玺荣那个单抗也不用等了。

有时候报很大希望的却销声匿迹了,不报希望的还能给人惊喜,希望这些药都能像鲁索一样,从理论到上市,我们一步步看着成功!

安立玺荣是不是也是基于这个理论的发现来开发的药物? 看他们公众号也提及过这篇文章

咱们都不是专业的人,但是现在至少有两家专业的公司,招募了几百个人在做专业的实验,我还是相信有成功的可能性。

谢谢分享,加拿大那个二期临床的eb06就是基于这个理论开发的,说的是根据一期研究证明可以持久逆转白白。

可以持久逆转白白,那不就相当于功克吗

不知道我的理解对不对,这个文章的意思是不是说以后通过血液或者皮肤局部检测,通过cxcl9.10   ifny这些检测可以看出白白处于什么期活动期稳定期什么的,通过这个监测可以活动期注射这个单抗,

通过infy处理后,黑色素活性降低,所以这个抗体抑制infy,所以对白白有效果,而单独cxcl10处理黑色素没有变化所以单独抑制效果不知道好不好,不过白白发病机制估计很多人都不同,说不了有的人抑制infu有效果,有的抑制cxcl10,有效果,就像现在有的鲁索有用有的没用一样,具体怎么样,等待实验结果总会有人研究就有希望,就是好事
