Timber Enrolls First Patients in Phase 3 ASCEND Clinical Trial after Receiving Breakthrough Designation from FDA for Lead Asset TMB-001 BASKING RIDGE, NJ, Aug. 11, 2022 (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 provided a business update and announced financial results for the second quarter of 2022, ended June 30, 2022. John Koconis, Chairman and Chief Executive Officer of Timber, commented, “During the second quarter, Timber achieved several significant milestones for our lead asset, TMB-001. These include the launch and enrollment of the first patients for the pivotal Phase 3 ASCEND study, and the receipt of Breakthrough Therapy designation from the FDA in May and Fast Track designation in April. Breakthrough Therapy designation especially isn’t granted often, and we believe that this underscores the FDA’s recognition of the potential benefit of our treatment to address the significant unmet need for patients with moderate to severe Congenital Ichthyosis, who have very limited therapeutic options.” “In our studies to date, Timber’s patented IPEGTM delivery system has demonstrated that it may result in substantially less systemic exposure to isotretinoin compared to oral retinoids. This will enable our topical formulation to deliver isotretinoin directly to the target skin, potentially providing efficacy and relief to patients while mitigating systemic toxicity. We were very excited to kick off the pivotal Phase 3 ASCEND clinical trial in June, which has been designed for a larger patient group to be studied over a longer time frame. Our clinical team is also expected to present further analysis of the compelling Phase 2b data at additional medical conferences both here and abroad in the coming months. Timber ended the quarter with approximately $8.3 million in cash and subsequently completed an $8 million financing in August,” concluded Mr. Koconis. Recent Highlights On June 23, 2022, Timber announced that it had enrolled the first patients in its Phase 3 ASCEND clinical trial evaluating its lead asset, TMB-001, a topical isotretinoin formulated using Timber’s patented IPEGTM delivery system, for the treatment of X-linked recessive ichthyosis (XRI) and autosomal recessive congenital ichthyosis lamellar ichthyosis (ARCI-LI). The pivotal trial expected to enroll more than 140 patients with moderate to severe Congenital Ichthyosis at leading research centers in the U.S., Canada, Italy, France, and Germany.In May 2022, Timber received Breakthrough Therapy Designation from the U.S. Food and Drug Administration (FDA) for TMB-001. Breakthrough Therapy designation is a process designed to expedite the development and review of drugs that are intended to treat serious or life-threatening conditions and that have demonstrated substantial improvement over available therapy on a clinically significant endpoint in preliminary clinical evidence. In April 2022, Timber announced that FDA granted Fast Track designation to TMB-001. Fast Track status facilitates the development and expedites the review of drugs that treat serious conditions and fill an unmet medical need. Results from the previously completed Phase 2b CONTROL study that demonstrated clinically meaningful efficacy with a favorable safety profile for TMB-001 were recently published on-line pre-proof in the world renowned, peer-reviewed Journal of the American Academy of Dermatology. Timber expects to present additional analysis of its study data on TMB-001 at several U.S. and international medical conferences in the coming months. Timber recognized no revenue in the second quarter of 2022 compared to revenue of $388,819 for the second quarter of 2021. First the first six months of 2022, Timber recognized revenue of $83,177 in the 2022 period and $429,553 in the 2021 period. Revenue for all periods consisted of reimbursements from achieving certain clinical milestones in the development of TMB-001, part of a $1.5 million grant from the FDA’s Orphan Products Clinical Trials Grants Program. Timber ended the second quarter with approximately $8.3 million in cash and 63.75 common shares outstanding. On August 8, 2022, Timber completed an $8 million public offering consisting of common shares and warrants.
