Sanofi to present Phase 2 detailed results of its brain-penetrant BTK inhibitor in relapsing multiple sclerosis

PARIS – April 17, 2020 – Sanofi will host a scientific session to present detailed data from their Phase 2b trial evaluating its investigational BTK (Bruton’s tyrosine kinase) inhibitor (SAR442168), an oral, brain-penetrant, selective small molecule. In February, the company reported that the study’s primary endpoint was met, demonstrating that the BTK inhibitor significantly reduced disease activity associated with multiple sclerosis (MS) as measured by magnetic resonance imaging.

“During these unprecedented times we remain committed to sharing results that allow us to advance the understanding of multiple sclerosis and the impact our potential brain-penetrant BTK inhibitor could have on the lives of people living with this disease,” said John C. Reed, M.D. Ph.D. Sanofi’s Global Head of Research & Development. “Our virtual session will provide the opportunity for an important scientific exchange and a forum for sharing the recent clinical results obtained with our brain-penetrant BTK inhibitor for multiple sclerosis.”

Sanofi is hosting this scientific session as a result of the cancellation of the live American Academy of Neurology (AAN) annual meeting due to the COVID-19 pandemic. The virtual scientific session will be held on April 23 from 8:00-9:00am EST/2:00-3:00pm CET; to register, click here. No pre-registration available for the event.

Audio webcast and conference call will be open to healthcare professionals and healthcare media. It will include presentations followed by Q&A session and live access to the speakers including: Daniel Reich, MD, PhD, Senior Investigator at NIH and Chief of the Translational Neuroradiology Section in the National Institute of Neurological Disorders and Stroke; Ross Gruber, PhD, Principal Scientist at Sanofi Genzyme; and Anthony Traboulsee, MD, Professor and Research Chair of the MS Society of Canada at the University of British Columbia in Vancouver, Canada

Topics to be highlighted which were planned to be presented at AAN:

In the US and Europe, there are approximately 1.2 million people diagnosed with MS, an unpredictable, chronic disease that attacks the central nervous system. Despite current treatments, many people with MS continue to accumulate disability, and one in four suffer from progressive forms of the disease with limited or no treatments available.

The efficacy and safety of Sanofi’s BTK inhibitor has not been confirmed by any regulatory authority.

Sanofi and Luminostics to join forces on developing breakthrough COVID-19 smartphone-based self-testing solution

PARIS - April 16, 2020 - Sanofi and Luminostics have signed an agreement to evaluate a collaboration on a unique self-testing solution for COVID-19, using Luminostics’ innovative technology, and further adding to Sanofi’s ongoing efforts to fight the COVID-19 pandemic on multiple fronts.

Luminostics would contribute its proprietary technology for consumer-diagnostics for COVID-19 testing while Sanofi would bring its clinical research testing experience and capabilities. The goal is to provide a smartphone-based solution that eliminates the current need for healthcare professional administration or laboratory tests.

“This partnering project could lead to another important milestone in Sanofi’s fight against COVID-19. The development of a self-testing solution with Luminostics could help provide clarity to an individual – in minutes – on whether or not they are infected” says Alan Main, Executive Vice President, Head of Sanofi Consumer Healthcare. “Following this week’s announcement of an unprecedented partnership with GSK in the hunt for a vaccine, our company’s ambition is to continue to find other ways to help solve this pandemic situation.”

The goal of this collaboration is to provide a consumer-based test that can detect the COVID-19 virus with high sensitivity and specificity from respiratory samples. The total time from specimen collection to results is expected in the range of 30 minutes or less. It is based on Luminostics’ unique technology that utilizes a consumer smartphone’s optics, controlled by an iOS/Android app paired with an inexpensive adapter, in combination with “glow-in-the-dark” nanochemistry and signal processing artificial intelligence.

The diagnostic platform is composed of:

During the current COVID-19 crisis it became obvious that rapid, reliable mass testing is one of the key strategies for successful containment of a pandemic outbreak. While point-of-care tests were made available relatively quickly - although not in a sufficient quantity - no over-the-counter (OTC) self-testing solution is currently available. A rapid self-testing solution would come with multiple advantages, including:

As one of the leading companies in the fight against COVID-19, Sanofi is already engaged in multiple clinical trials evaluating current treatment options (Kevzara^® and Plaquenil^®) in patients suffering from COVID-19 as well as two vaccine programs.

Based on Luminostics’ existing technology and protypes, both companies envisage to start development activities in the coming weeks. In parallel, both parties expect to execute a final collaboration agreement including a plan for accelerated ramp up of necessary manufacturing capabilities. If development activities can be successfully conducted, the aim is to have an OTC self-testing solution ready before the end of 2020, subject to obtaining required regulatory clearances.
