SRRA stock ran up 12% in after-hours trading (brown shaded area) on December 5, 2019.

On December 2, 2019, Sierra Oncology, Inc. (Nasdaq: SRRA), a late-stage drug development company focused on the development and commercialization of momelotinib, a JAK1, JAK2 & ACVR1 inhibitor with a potentially differentiated therapeutic profile for the treatment of myelofibrosis, announced that it will host an Analyst & Investor Event on Sunday, December 8th at 7:00 am ET to discuss newly reported clinical data for momelotinib that will be presented at the 61st American Society of Hematology (ASH) Annual Meeting in Orlando, Florida.

The event will be led by Dr. Nick Glover, President and CEO of Sierra Oncology, and will include a presentation by renowned myelofibrosis expert, Dr. Ruben Mesa, Director of the Mays Cancer Center, home to UT Health San Antonio MD Anderson Cancer Center. Dr. Mesa and members of Sierra Oncology’s senior management team will be available to answer questions at the conclusion of the event.

New analyses of RBC transfusion data from SIMPLIFY-1, a double-blind Phase 3 trial of Sierra’s investigational drug momelotinib head-to-head versus ruxolitinib in JAK inhibitor naïve patients, will be presented in a poster by Dr. Mesa on Saturday, December 7th at the ASH Annual Meeting. These analyses demonstrate that patients who received momelotinib had significantly decreased transfusion requirements compared to those treated with ruxolitinib, including a nearly 10-fold higher odds of receiving no transfusions during the 24-week study period.

On December 5, 2019, right after regular trading closed, Oppenheimer analyst Jay Olson initiated coverage of Sierra Oncology with an Outperform rating and $1.20 price target. He sees “significant commercial potential” for the company’s main asset, momelotinib, viewing it as as well positioned to secure second-line treatment of myelofibrosis patients previously treated with a JAK inhibitor, Olson tells investors. SRRA stock immediately exploded after the analyst’s comments, running up 12% in after-hours trading.
