About INHIBITOR Therapeutics, Inc.

INHIBITOR Therapeutics, Inc. (OTCQB:INTI) is a pharmaceutical development company that discovers, develops and plans to commercialize innovative therapeutics to inhibit the progression of cancerous and non-cancerous proliferation disorders. INTI is the exclusive U.S. licensee of SUBA^™-Itraconazole in certain fields. Clinical studies have shown SUBA-Itraconazole to have greater bioavailability than generic itraconazole, a drug approved by FDA for the treatment of certain fungal infections. The Hedgehog signaling pathway is a major regulator of cellular processes in vertebrates, including cell differentiation, tissue polarity and cell proliferation. Based on published research, INHIBITOR believes that inhibiting the Hedgehog pathway could delay or possibly prevent the development and progression of certain cancers, such as prostate cancer, in humans. Leveraging research undertaken by key investigators in the field, INHIBITOR is exploring the effectiveness of SUBA-Itraconazole as an anti-cancer agent to pursue its potential commercialization. INHIBITOR is headquartered in Tampa, Florida. For more information, please visit www.inhibitortx.com.
