Quince Therapeutics Appoints Recognized Leaders in Pulmonary Medicine to Scientific Advisory Board

SOUTH SAN FRANCISCO, Calif., June 30, 2026 (GLOBE NEWSWIRE) -- Quince Therapeutics, Inc. (NASDAQ:QNCX), a clinical stage biopharmaceutical company focused on the development of novel, disease modifying therapies for serious underserved diseases, today announced the formation of a Scientific Advisory Board (SAB) of leading clinicians to support the advancement of LAM-001, an inhaled formulation of rapamycin (mTOR inhibitor) designed to enhance pulmonary delivery and reduce systemic exposure.

Comprised of internationally recognized experts in pulmonary medicine, the SAB will be instrumental in progressing the development of LAM-001 across multiple pulmonary indications including pulmonary hypertension associated with interstitial lung disease (PH-ILD), bronchiolitis obliterans syndrome post lung transplant (BOS), and sarcoidosis associated pulmonary hypertension (SAPH).

"I am honored to serve as the Chairman of Quince’s Scientific Advisory Board to help guide the development of LAM-001 across a range of pulmonary conditions where evidence strongly suggests it has a direct effect on the underlying disease pathophysiology," commented Paul Yu, M.D., Ph.D., Director, Cardiovascular Research Center, Massachusetts General Hospital. "On behalf of the SAB, we are encouraged by the clinically relevant improvement seen in measures of lung function in patients with functional class III pulmonary hypertension treated with LAM-001. With continued development, we believe LAM-001 has the potential to provide patients with a much needed treatment option that, importantly, may be utilized in conjunction with currently available therapies to achieve better health outcomes."

About LAM-001

LAM-001 is a proprietary, investigational, once-daily inhaled formulation of sirolimus, also known as rapamycin. LAM-001’s potential as a disease-modifying agent in pulmonary hypertension stems from its ability to inhibit mTOR-mediated pulmonary arterial smooth muscle cell proliferation. The mTOR pathway has been shown to be activated in the pulmonary arterial smooth muscle cells of patients with pulmonary hypertension, and mTOR inhibition with rapamycin has been shown to reverse smooth muscle cell hyperproliferation and attenuate pulmonary vascular remodeling and cardiopulmonary dysfunction in multiple nonclinical models. Additionally, mTOR signaling promotes fibroblast activation, myofibroblast differentiation, and extracellular matrix deposition in injured or inflamed lung tissue, and mTOR inhibition has been shown to exert direct anti-fibrotic activity, reducing collagen accumulation, suppressing profibrotic cytokine signaling, and attenuating parenchymal fibrosis. These effects are particularly relevant in PH-ILD, where vascular remodeling and progressive fibrosis evolve in parallel and amplify pulmonary vascular load. LAM-001 is designed to enhance pulmonary delivery and reduce systemic exposure, offering a promising potential disease-modifying therapy for pulmonary disease.

LAM-001 is currently being studied in multiple indications including PH-ILD, a serious and progressive condition affecting an estimated ~86K patients in the U.S. and ~120K in Europe. Based on compelling Phase 2a data presented at the American Thoracic Society (ATS) in May 2026, the company is advancing LAM-001 into a Phase 2b trial in PH-ILD, with initiation planned for mid-2026 and data anticipated in the first quarter of 2028. LAM-001 is also being evaluated in a Phase 2 study in BOS, a serious complication following lung transplantation affecting an estimated ~17K patients in the U.S. and ~11K in Europe. The trial is fully enrolled, with data anticipated in the first quarter of 2027. In late 2026, the company also plans to initiate a Phase 2 study of LAM-001 in SAPH, a severe complication of sarcoidosis with no approved therapy affecting an estimated ~60K patients in the U.S. and Europe.
