Novartis to acquire Ziarco to expand dermatology portfolio

Published 19 December 2016

Novartis has agreed to acquire Ziarco Group, a privately held firm engaged in the development of novel treatments in dermatology.

This acquisition would add a once-daily oral H4 receptor antagonist in development for atopic dermatitis (AD), commonly known as eczema, to complement the growing Novartis dermatology portfolio and pipeline.

The transaction is subject to customary closing conditions, including regulatory approval. The financial details of this transaction are not disclosed.

Ziarco's lead investigational product, ZPL389, is a potential first-in-class oral treatment for moderate-to-severe eczema. Eczema is a chronic, itchy, inflammatory skin condition found in millions of children and adults worldwide.

In addition, it is associated with sleep loss and a significant reduction in quality of life. Currently, no safe, effective, and well-tolerated oral treatments are available for the moderate-to-severe form of this condition.

Novartis drug development global head and chief medical officer Vasant Narasimhan said: "There is an unmet need for innovative, effective and safe oral treatment options for people living with eczema.

"We are proud of our dermatology capabilities shown by the recent successful launches of Cosentyx and Xolair. Now we're excited about a potential new medicine for people with eczema through the acquisition of Ziarco and the addition of a first-in-class oral H4 receptor antagonist to our growing pipeline."

In a proof of concept study, ZPL389 showed a clinically and statistically significant reduction of eczema. After eight weeks of treatment, the compound reduced the Eczema Area and Severity Index (EASI) score by 50% (placebo: 27%, (p=0.01)) in a study of 98 patients. In addition, there was a statistically significant improvement in SCORing Atopic Dermatitis (SCORAD) and body surface area (BSA) scores affected by eczema for ZPL389.

The study also showed a decrease in itching, which was numerically greater in the active treatment arm. Both the EASI and SCORAD sub-scores related to itching showed positive results and there was a statistically significant decrease in sleep loss for the active comparator.

Itch is a major cause for sleep loss in eczema patients. In clinical studies conducted to date, ZPL389 has a favorable safety profile.

Eczema poses a significant burden on health-care resources and patients' quality of life with recent data showing that its prevalence is still increasing.

Eczema affects up to 10% of the population in the US alone, with approximately 15% of children and 70% of adults having the moderate-to-severe form of the disease. Treatment does not cure eczema but can control symptoms and potentially improve quality of life.
