Attenua, Inc., a clinical-stage biopharmaceutical company focused on developing novel medicines to treat cough, today announced the completion of a $35 million Series A financing. The financing was led by Omega Funds with participation from a syndicate of leading international healthcare investors including Abingworth, OrbiMed and Redmile Group LLC.

Michael Kitt, MD, has joined Attenua as CEO with the financing. Dr. Kitt was previously Chief Medical Officer at Afferent Pharmaceuticals, Inc., where he successfully led clinical trials in cough leading to the company's $1.25 billion acquisition by Merck & Co., Inc in 2016.

The new capital will be used to further develop Attenua's lead drug candidate ATA-101, which targets a new mechanism for chronic cough, in Phase 2 clinical trials, as well as to progress the company's pipeline.

In conjunction with the financing, Michael Kitt, MD, CEO; Dina Chaya, Advisor to Omega Funds; Kurt von Emster, Managing Partner at Abingworth; and Rishi Gupta, Private Equity Partner at OrbiMed, will join Attenua's board of directors. They will join existing members Hugh Rienhoff, Chairman, and Jing Liang, PhD, Founder and Former CEO of Attenua.

"I was inspired to join Attenua at this pivotal moment because of the compound profile and potential of ATA-101 to have a significant impact on the treatment of cough. We anticipate launching a proof-of-concept clinical study for ATA-101 in chronic cough later this year," said Dr. Kitt, CEO of Attenua.

Dina Chaya, Advisor to Omega Funds, said: "We saw a unique opportunity with Attenua to lead this financing, and are looking forward to working with Michael and the Attenua team. Chronic cough remains a significant unmet need affecting more than 2.5 million people in the U.S. alone."

Jing Liang, PhD, founder of Attenua and Board member, added, "We are pleased with the strong support and recognition that we have achieved in this Series A financing and look forward to evaluating Attenua's lead candidate in the clinic."

About Chronic Cough
Cough is a symptom for which patients frequently seek medical attention. Cough can be classified as acute, lasting for up to three weeks, subacute, lasting from three to eight weeks or chronic, lasting for more than eight weeks. The prevalence of chronic cough is estimated to be over 10% of adults in the United States. While underlying etiologies may contribute to cough in some of these patients (such as gastro-intestinal reflux disease, asthma or chronic obstructive pulmonary disease), many patients are not well-controlled for their cough even with treatment for these underlying causes. No therapies are approved for the treatment of chronic cough.
