Company Plans to Initiate Phase 3 Study for TMB-001 in Q2 2022 BASKING RIDGE, NJ, March 31, 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 fourth quarter and year ended December 31, 2021. John Koconis, Chairman and Chief Executive Officer of Timber, commented, “Timber achieved multiple milestones over the past few months. In October, we reported positive topline data for our lead asset TMB-001 and just a few weeks ago, we had a productive follow-up meeting with the FDA, positioning us to launch a Phase 3 study in the second quarter of 2022. We also anticipate reporting top line data for the recently completed Phase 2b study for TMB-002 in the third quarter of this year. It’s an exciting time at Timber as we move into late-stage clinical development for our two lead assets.” Recent Highlights During the fourth quarter, Timber announced positive top line results of its Phase 2b CONTROL Study of congenital ichthyosis (CI) for its lead asset, TMB-001, a topical isotretinoin formulated using the company’s patented IPEG™ delivery system. Clinically meaningful efficacy with a favorable safety profile demonstrated the potential of TMB-001 to be an important option for the treatment of CI where no FDA-approved treatments are currently available and the options for standard of care is limited. Timber presented the TMB-001 Phase 2b study results at the European Academy of Dermatology and Venereology’s (EADV) 30th anniversary congress that was held virtually from September 29 – October 2, 2021. Full data was also presented at the 2022 Winter Clinical Dermatology Conference held January 14 – 19, 2022 in Koloa, Hawaii. In addition, a late-breaking presentation of a sub-analysis of the TMB-001 Phase 2b study was presented by a third party at the American Academy of Dermatology 2022 Annual Meeting held March 25-29, 2022 in Boston, Massachusetts. In February 2022, Timber announced the successful completion of an End-of-Phase 2 meeting with the U.S. Food and Drug Administration (FDA) that resulted in a clear path to the launch of a pivotal Phase 3 study for TMB-001. Timber plans to initiate the Phase 3 study in the second quarter of 2022. Timber ended the fourth quarter with $16.8 million in cash and common shares outstanding of 63.6 million on December 31, 2021. This includes $17.25 million in total gross proceeds from a successful public offering that closed in November 2021. Timber recognized revenue of $190,005 in the fourth quarter of 2021 compared to $102,382 for the fourth quarter of 2020. Revenue for both 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. For the twelve months ended December 31, 2021, Timber recognized revenue of $886,532 compared to $453,810 for the prior year. Reimbursements from achieving certain clinical milestones in the development of TMB-001, totaled $590,794 compared to $453,810 for 2020, part of a $1.5 million grant from the FDA’s Orphan Products Clinical Trials Grants Program.
