CAMBRIDGE, Mass., December 4, 2023
Cyclerion Therapeutics, Inc. (Nasdaq: CYCN), a biopharmaceutical company on a mission to develop treatments for serious diseases, today announced that Regina Graul, Ph.D., has joined the company as president, effective immediately. As
Cyclerions president, she will lead the organization and will work closely with, and report directly to, the board of directors. She will be responsible for creating, implementing, and executing strategy as well as building a uniquely talented
cross-functional management team.
With Grauls arrival, transitional commitments under the asset purchase agreement with Tisento Therapeutics
completed, and general expense reductions largely in place, founding chief executive officer Peter Hecht, Ph.D. has completed his transitional assignment. As a result, he is stepping away from an operational role at Cyclerion, effective immediately,
and will continue to work with Dr. Graul and her team as a strategic consultant and board director going forward.
I am thrilled to be joining
Cyclerion at this pivotal moment. The recent additions of Dina Katabi and Michael Higgins as board members and the evolution of Cyclerions board and management team provide a key inflection point to
re-envision the companys future, said Dr. Graul. As we evaluate our existing assets and identify external value-creating opportunities, cutting-edge innovation and addressing unmet
patient needs will be central tenets. Together with our outstanding board of directors, I look forward to building Cyclerions capabilities for its next chapter to bring meaningful medicines to the patients who need them most.
I am optimistic about the future of Cyclerion with Regina shepherding the company, a top-notch board of
directors, promising existing assets, and a strategy for growth and evolution through external innovation, said Dr. Hecht. Having worked with Regina personally for years at Microbia, Ironwood, and Cyclerion, I can attest to her
effective leadership style, savvy sense of strategy, and ability to identify and advance promising science. I look forward to working with her and the rest of the board as we build the next phase of the company and seek to make important progress on
behalf of patients.
Regina most recently served as vice president, program executive at EQRx, where she led cross-functional development teams in
oncology, using the latest in clinical innovation to create and deliver sustainable solutions. Previously, she served as olinciguat program lead at Cyclerion where she oversaw all aspects of olinciguat research and development. She began her
industry career at Ironwood Pharmaceuticals (formerly Microbia Inc.) after completing a postdoctorate at MIT. She received her Ph.D. in synthetic organic chemistry from Rice University and her B.A. in chemistry from Saint Anselm College.
