Ra Pharmaceuticals Supports 13th Annual Rare Disease Day® and Joins Global Movement to Raise Awareness for Rare Diseases

CAMBRIDGE, Mass.--()--Ra Pharmaceuticals, Inc. (Nasdaq:RARX) is joining forces with 30 million healthcare advocates around the world for the 13th Annual Rare Disease Day®, an awareness day dedicated to elevating public understanding of rare diseases and calling attention to the special challenges people living with rare diseases face.

At Ra Pharma, our primary focus is the patients and communities we serve. These patients, families, and caregivers are at the core of our effort to develop innovative and accessible therapies for rare complement-mediated diseases,” said Doug Treco, Ph.D., President and Chief Executive Officer of Ra Pharma. “We achieved progress across our rare disease programs in 2019, including the initiation of a pivotal Phase 3 study in generalized myasthenia gravis and a Phase 2 study in immune-mediated necrotizing myopathy, yet significant work remains in the global effort to improve the lives of people living with rare diseases. This Rare Disease Day, we extend our great appreciation to these families and patients for their bravery and strength.”

According to the National Institutes of Health, there are more than 6,000 rare diseases known today that affect more than 25 million people in the United States. In the U.S., a disease is defined as rare if it affects fewer than 200,000 people.

About Rare Disease Day

Rare Disease Day takes place every year on the last day of February to raise awareness among the general public and decision-makers about rare diseases and their impact on patients’ lives. It was established in 2008 by EURORDIS, the organization representing rare disease patients in Europe, and is now observed in more than 80 nations. In the U.S., Rare Disease Day is sponsored by the National Organization for Rare Disorders (NORD®), the largest and leading independent, non-profit organization committed to the identification, treatment, and cure of rare diseases.
