Rhythm Pharmaceuticals Announces Leadership Transition

Keith Gottesdiener, M.D. to Step Down as Chief Executive Officer Following NDA Submission for Setmelanotide in POMC and LEPR Deficiency Obesities Expected in the First Quarter of 2020

Board Forms Search Committee to Assist in Identifying Successor

BOSTON, Jan. 06, 2020 (GLOBE NEWSWIRE) -- Rhythm Pharmaceuticals, Inc. (RYTM), a biopharmaceutical company aimed at developing and commercializing therapies for the treatment of rare genetic disorders of obesity, today announced that Keith Gottesdiener, M.D., intends to step down as Chief Executive Officer, President and a member of the Company’s Board of Directors. The Board has formed a search committee and retained an executive search firm to assist in identifying Dr. Gottesdiener’s successor. Dr. Gottesdiener plans to serve in his current role until the completion of the Company’s submission of its New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA).

“On behalf of the entire Board of Directors, I want to thank Keith for his significant contributions to Rhythm,” said David Meeker, M.D., Chairman of the Board. “Under Keith’s leadership, Rhythm has become a recognized leader in rare genetic disorders of obesity, advancing setmelanotide through late-stage clinical development in four indications, identifying additional melanocortin-4 receptor (MC4R) pathway disorders that may be amenable to treatment, and building a robust community of healthcare providers, advocacy groups, patients and families to better understand, identify and treat people living with these conditions. We wish him the best in his future endeavors.”

Dr. Meeker continued, “As Rhythm prepares to enter its next chapter as a commercial company, now is an appropriate time to initiate this transition. We believe Rhythm has a strong management team, is well capitalized, and all of its major milestones are on track, including the planned submission of our first NDA to the FDA. We are confident this will be a smooth transition as we work to identify the next leader for Rhythm and continue to execute on our mission of transforming the standard of care for people with rare genetic disorders of obesity.”

“For the more than eight years that I have been CEO, it has been an honor to lead the talented Rhythm team, and I am immensely proud of our work to advance setmelanotide and bolster the understanding of rare genetic disorders of obesity,” said Dr. Gottesdiener. “With the completion of our first Phase 3 trials and our pending NDA submission, it is a natural time for me to pass the baton and for Rhythm to welcome new leadership. I am confident that Rhythm is in an excellent position to deliver on the potential of setmelanotide, and I look forward to working with the Board and leadership team over the next several months to ensure a smooth transition.”

In August of 2019, Rhythm announced the achievement of positive topline results from its pivotal Phase 3 clinical trials evaluating setmelanotide, the Company’s MC4R agonist, for the treatment of pro-opiomelanocortin (POMC) and leptin receptor (LEPR) deficiency obesities.

Rhythm remains on track to complete the submission of a rolling NDA to the FDA that will cover both POMC and LEPR deficiency obesities in the first quarter of 2020. Rhythm also reiterates its previous guidance on other major milestones and continues to expect topline data from its Phase 3 trial evaluating setmelanotide in Bardet-Biedl and Alström syndromes in the fourth quarter of 2020 or early in the first quarter of 2021. Additionally, Rhythm is well capitalized, and believes it has sufficient resources to fund its operations through at least the end of 2021.
