Ad Scientiam announces agreement with Johnson & Johnson Innovation to develop a digital assessment scale for Major Depressive Disorders

PARIS, France - Nov. 7, 2018 - Amzeal -- Ad Scientiam announced today that it has entered into a collaboration with Janssen Pharmaceutica NV to develop a mobile medical application designed to predict anti-depressant treatment response in real life. This deal was facilitated by Johnson & Johnson Innovation.

Major depressive disorder (MDD) affects nearly 300 million people of all ages globally and is the leading cause of disability worldwide. Individuals with depression, including MDD, experience continuous suffering from a serious, biologically based disease which has a significant negative impact on all aspects of life, including quality of life and function.

Although currently available antidepressants (AD) are effective for many patients, about one third of patients do not respond to treatment and are considered to have treatment-resistant depression[ii].

In addition, current depression assessment scales are not specifically designed for an early identification of people with treatment-resistant depression. Thus, patients with inadequate response to treatment often have to wait for weeks or months before being diagnosed and properly treated.

Ad Scientiam will design and develop a mobile medical application, to detect, among an important array of signs and symptoms, early markers of response and non-response to an AD treatment.

The application consists of several modules, each collecting real-world patient data

"Ad Scientiam has built a strong expertise in the development of innovative mobile medical applications, based on real-world patient data. This new solution will provide regular, contextualized, multi-dimensional collection of patients' depressive symptoms and will allow us to identify, as early as Week 2, non-responders to an AD treatment and ultimately improve the clinician's decision-making process" explains Dr. Saad Zinaï, Ad Scientiam's Chief Medical Officer.

This assumption will be tested in patients with depression during a clinical study conducted in France, sponsored by Ad Scientiam, and coordinated by Pr. Bruno Millet (department of psychiatry, La Pitié-Salpêtrière hospital).

Ad Scientiam will compare the global digital score and each of its dimension in patients showing adequate response to treatment to those showing no or insufficient response.

The mobile application acceptability in patients and investigators and its safety will also be measured.

"Since the creation of our company in 2013, we have benefited from the dynamism, innovation and proximity with research teams offered by La Pitie Salpetriere and the Brain and Spine Institute (ICM). We are very excited to embark on this new project with them. The support from Janssen is crucial to accelerate the project development and we are eager to start this collaboration." adds Liouma Tokitsu, Ad Scientiam's Founder and Chief Executive Officer.

Ad Scientiam is preparing the IRB submission of the study protocol and the development of the mobile application. The recruitments are expected to start in the second quarter of 2019.
