Current TAP Partner

WATERTOWN, Mass., March 02, 2021 (GLOBE NEWSWIRE) -- Kymera Therapeutics, Inc. (NASDAQ: KYMR), a clinical-stage biopharmaceutical company advancing targeted protein degradation to deliver novel small molecule protein degrader medicines, today announced that the Company recently initiated dosing in the single ascending dose (SAD) portion of the Phase 1 clinical trial evaluating KT-474 in adult healthy volunteers and patients with atopic dermatitis or hidradenitis suppurativa. KT-474 is a potential first-in-class, highly active and selective, orally bioavailable IRAK4 degrader being developed for the treatment of toll-like receptor (TLR)/interleukin-1 receptor (IL-1R)-driven immune-inflammatory diseases, such as atopic dermatitis, hidradenitis suppurativa, rheumatoid arthritis and potentially other indications.

The first-in-human Phase 1 trial is a randomized, double-blind, placebo-controlled, single and multiple ascending dose study designed to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of orally administered KT-474 in adult healthy volunteers and patients with atopic dermatitis or hidradenitis suppurativa. Additional information on this clinical trial can be found on www.clinicaltrials.gov.

“KT-474 is the first heterobifunctional protein degrader candidate to advance into the clinic for immune-inflammatory conditions, representing a significant achievement for Kymera and an important milestone for the whole field of targeted protein degradation,” said Nello Mainolfi, PhD, Co-Founder, President and CEO, Kymera Therapeutics. “I am proud of the progress that our R&D organization has made to advance our first program into the clinic in only four years, and we are looking forward to the initiation of our IRAKIMiD and STAT3 Phase 1 oncology trials in 2021, setting up a transformational year for Kymera.”
