Atara Biotherapeutics Joins the Rare Disease Company Coalition Alongside Industry Gamechangers

Initiative aims to advance timely access to innovative therapies for those living with rare conditions

SOUTH SAN FRANCISCO, Calif.--()--Atara Biotherapeutics, Inc. (Nasdaq: ATRA), a pioneer in T-cell immunotherapy, leveraging its novel allogeneic EBV T-cell platform to develop transformative therapies for patients with cancer and autoimmune diseases, today announced the Company has joined the Rare Disease Company Coalition. The coalition represents an alliance of innovative life sciences companies committed to discovering, developing and delivering rare disease treatments for the patients they serve.

Patients living with Epstein-Barr virus-driven post-transplant lymphoproliferative disease (EBV+ PTLD), a rare blood cancer that may develop following a life-saving solid organ or stem cell transplant, are in critical need of therapies specifically designed to effectively and safely treat their condition,” said AJ Joshi, M.D., Chief Medical Officer at Atara. “As Atara strives to address this unmet need, we must work in concert with industry and policy makers to advance effective policies that encourage continued innovation and acceleration of safe and potentially life-saving allogeneic cell therapies for rare and ultra-rare diseases such as PTLD and other EBV-driven hematologic and solid tumors. We are grateful to be among our peers who share this motivation and look forward to advancing these initiatives together.”

The collective goal of the Coalition is to inform policymakers of the novel promise of these treatments and unique challenges faced in taking rare disease therapies from research and development through to commercialization. The Coalition will advocate for policy and regulatory frameworks that take into account considerations of innovators in the rare disease space and their important impact on delivering therapies to the patients they serve.

Upcoming initiatives and work of the Coalition include continued engagement with policymakers on the unique needs of the rare disease community, the urgency of and support for innovation to address significant unmet patient need and dialogue around policies that advocate for timely and appropriate access to safe and transformational treatments.
