Timber Pharmaceuticals Receives Orphan Drug Designation from U.S. FDA for TMB-003 for the Treatment of Systemic Sclerosis

Timber Expects to Submit Investigational New Drug (IND) Application to the FDA in 2022

WOODCLIFF LAKE, N.J., Jan. 12, 2021 (GLOBE NEWSWIRE) -- via NewMediaWire -- Timber Pharmaceuticals, Inc. ("Timber" or the “Company”) (NYSE American: TMBR), a biopharmaceutical company focused on the development and commercialization of treatments for rare and orphan dermatologic diseases, today announced that the U.S. Food and Drug Administration (FDA) has granted orphan drug designation to TMB-003, the company’s locally delivered formulation of sitaxsentan, for the treatment of systemic sclerosis.

“People who are living with systemic sclerosis or scleroderma often struggle with their quality of life because the condition can be disfiguring and may cover joints and cause pain that affects movement and mobility,” said John Koconis, Chief Executive Officer of Timber. “Currently there is no FDA approved treatment for any cutaneous symptoms in scleroderma. We are pleased to receive orphan drug designation for our investigational treatment and look forward to advancing into clinical stage research.”

The Orphan Drug Designation program provides orphan status to drugs and biologics that are intended for the treatment, prevention or diagnosis of a rare disease or condition that affects less than 200,000 people in the U.S. Systemic sclerosis is a group of rare autoimmune connective tissue disorders (CTD) characterized by inflammation and thickening of the skin and other connective tissues from excessive collagen deposition. Systemic sclerosis leads to abnormalities in the skin, joints, and internal organs.

Sitaxsentan is a highly selective endothelin (ET-A) receptor antagonist, which is a class of drugs previously developed in oral form for the treatment of pulmonary arterial hypertension (PAH). TMB-003 is a locally delivered formulation of sitaxsentan that has the potential to reduce collagen while addressing systemic safety concerns associated with oral administration. Timber is in the preclinical stages of evaluating TMB-003 for the treatment of scleroderma and expects to submit an Investigational New Drug (IND) application to the FDA in 2022.
