ARTham announces first patient dosed in Phase 2 clinical trial of ART-648 in patients with bullous pemphigoid.

ARTham Therapeutics announced today that the first patient has been dosed in a Phase 2 clinical trial evaluating ART-648 as a potential treatment for bullous pemphigoid (jRCT2071210034). ART-648 is a novel orally available PDE4 selective inhibitor with excellent pharmacokinetic, pharmacodynamic and safety profile that have been demonstrated in its Phase 1 trial in healthy adults.

This Phase 2 trial is a multi-center, double-blind, placebo-control, randomized controlled study to evaluate the efficacy, safety, and pharmacokinetics of ART-648 in patients with bullous pemphigoid. The trial is enrolling a total of 30 patients. The primary endpoint of the trial is the proportion of patients achieving the cessation of new lesion formation (erosion/blister or wheal/erythema) without rescue therapy at week 4. Secondary endpoints include the proportion of patients achieving the cessation of new lesion formation without rescue therapy at week 2, changes from baseline to week 2 and 4 in bullous pemphigoid disease activity index (BPDAI) score, pruritus VAS score, and proportion of patients receiving rescue therapy at week 2 and 4.

 

About bullous pemphigoid

Bullous pemphigoid, one of the rare diseases in elderly population, is an autoimmune skin disease that causes edematous erythema, itchy blisters, and erosions of the skin and mucous membranes throughout the body. Bullous pemphigoid is most commonly treated with oral or topical corticosteroids. Anti-inflammatory medications may also be useful in mild cases. Severe cases may require the use of immunosuppressant medications. Oral corticosteroids can have serious side effects, so there is high demand for an effective anti-inflammatory agent, which tapers regimen of corticosteroid.

 

About ART-648

ART-648 is an orally available PDE4 inhibitor that is currently under development for bullous pemphigoid. ART-648 potently and selectively inhibits PDE4 enzyme and exhibits direct “anti-inflammatory,” “antimetabolite,” and “antifibrotic” effects in multiple disease relevant in vitro or in vivo models. In addition, ART-648 possesses superior physico-chemical properties, which contribute to tolerability profile similar or better to marketed PDE4 inhibitors demonstrated in its phase 1 study.

ARTham announces first patient dosed in Phase 2 clinical trial of ART-001 in patients with slow-flow vascular malformations.

ARTham Therapeutics announced today that the first patient has been dosed in a Phase 2 clinical trial evaluating ART-001 as a potential treatment for slow flow vascular malformations (jRCT2071210027). ART-001 is a novel PI3Kα selective inhibitor with excellent pharmacokinetic and safety profile that have been demonstrated in its Phase 1 trial in healthy adults.

This Phase 2 trial is a multi-center, double-blind, randomized controlled study to evaluate the efficacy, safety, and pharmacokinetics of ART-001 in pediatric (≥ 2 years old) and adult patients with slow-flow vascular malformations including venous malformation, lymphatic malformation (lymphangioma) and Klippel-Trenaunay syndrome. The trial is enrolling a total of 34 patients. The primary endpoint of the trial is the proportion of subjects with response defined by MRI volumetric change of target lesion at Week 24. Secondary efficacy endpoints include the proportion of subjects with response at Week 12, changes from baseline in MRI volume of target lesion, pain VAS, QOL score and performance status.

 

About slow flow vascular malformations

Slow-flow vascular malformations are benign (non-cancerous) lesions that are present at birth, and may become visible for weeks or months after birth. Unlike hemangiomas, vascular malformations continue to grow slowly throughout life. It has been reported that most patients with slow-flow vascular malformation have a gain-of-function mutation in PI3K pathway, which plays an important pathological role in vascular malformation.

 

About ART-001

ART-001 is an orally-available PI3Kα inhibitor that is currently under development for slow-flow vascular malformations. ART-001 potently and selectively inhibited PI3Kα and exhibits “antitumor effect” and “anti-angiogenesis effect” in in vitro and in vivo preclinical models. In addition, the excellent pharmacokinetic and safety profile with the new formulation was demonstrated in the Phase I study in healthy adults.

ARTham Therapeutics again receives the rare disease drug development grant from AMED for its ART-001 program (development for the treatment of slow-flow vascular malformations)

ARTham’s clinical program ART-001, an oral selective PI3Kα inhibitor, for slow-flow vascular malformations in both pediatric and adult population was awarded additional three-year R&D grant from “the Japan Agency for Medical Research and Development (AMED) Program for Orphan Drugs prior to Designation”.

Slow-flow vascular malformations are benign (non-cancerous) lesions that are present at birth, and may become visible for weeks or months after birth. Unlike hemangiomas, vascular malformations continue to grow slowly throughout life. It has been reported that most patients with slow-flow vascular malformation have a gain-of-function mutation in PI3K pathway, which plays an important pathological role in vascular formation. ART-001 inhibits PI3Kα with high selectivity, being expected to exert clinically meaningful therapeutic effect.

ART-001 program had been supported by AMED for last 3 years and had made a significant progress including new formulation development, completion of Ph-1 clinical trial as well as multiple clinical research to better understand the disease background such as gene mutation and natural history. Ph-2 clinical trial is anticipated to start in third quarter of 2021. ARTham is striving to deliver medicines that matter for patients.
