Gilead Sciences Statement on Remdesivir Clinical Data

Foster City, Calif., June 1, 2020 – Gilead Sciences today issued the following statement from Merdad Parsey, MD, PhD, Chief Medical Officer, Gilead Sciences, on the totality of clinical data on remdesivir to date:

“Since the earliest days of the outbreak, Gilead has been focused on rapidly studying the potential for our investigational antiviral remdesivir to treat patients with COVID-19. We set out to answer important questions about if, how and when to use remdesivir, conducting multiple studies in parallel and on a significantly compressed timeline, given the urgency of the public health need. Building on a foundation of knowledge from our earlier studies of remdesivir in other viruses, we have conducted one of the fastest ever late-stage development programs to bring forward a potential treatment for COVID-19. 

With the latest data announced today, we now have three randomized, controlled clinical trials demonstrating that remdesivir improved clinical outcomes by several different measures. Today’s SIMPLE-Moderate study results showed that when treating patients with moderate disease – those with pneumonia who do not require supplemental oxygen – a 5-day course of remdesivir led to greater clinical improvement than standard of care alone. The placebo-controlled study conducted by the National Institute of Allergy and Infectious Diseases demonstrated that remdesivir enabled more rapid recovery and that earlier treatment improved outcomes in patients with a range of disease severity. And our earlier SIMPLE-Severe study results showed that when treating patients with severe disease – those who require non-invasive supplemental oxygen – 5 days of remdesivir led to similar improvements as a 10-day course. The totality of clinical data shows that remdesivir has the potential to meaningfully benefit patients with COVID-19 and offers important hope.

With the additional data we have in hand today, we will continue to pursue research opportunities to evaluate patient outcomes and potentially benefit more patients with remdesivir. These include extending treatment earlier in the course of disease, combination studies with other therapies for the most critically ill patients, pediatric studies and the development of alternate formulations. We will continue to share emerging data with regulatory authorities as we work together to help address the needs of patients around the world.

We would like to thank the patients and healthcare providers who have participated in clinical trials of remdesivir to date. It is thanks to the collaboration of everyone involved that we have so rapidly advanced our understanding of remdesivir as a potential COVID-19 treatment.”
