Promedior Announces Presentation of Interim Phase 2 Data on PRM-151 in Myelofibrosis at ASCO
LEXINGTON, Mass., May 15, 2014 — Promedior, Inc.
, a clinical stage biotechnology company developing novel therapeutics for the treatment of fibrosis, today announced that principal investigator, Srdan Verstovsek, MD, PhD, will present interim data from the Company’s ongoing Phase 2 clinical trial of its lead product candidate, PRM-151, for the treatment of myelofibrosis, in a poster presentation on June 2, 2014 at the American Society for Clinical Oncology (ASCO) 2014 Annual Meeting. The reported data will include 24-week results in patients with myelofibrosis and will assess key clinical measures of efficacy and safety related to myelofibrosis.
With a novel mechanism of action that is targeted to prevent and reverse fibrosis, PRM-151 has the potential to address the fundamental fibrotic pathology of myelofibrosis. This Phase 2 clinical trial is a multi-center, two stage, adaptive design study to determine the efficacy and safety of PRM-151 as a single agent or added to a stable dose of ruxolitinib in patients with Primary Myelofibrosis (PMF), Post-Polycythemia Vera MF (post-PV MF), or Post-Essential Thrombocythemia MF (post-ET MF).
Details of the poster presentation at ASCO are as follows:

PRM-151, Promedior’s lead product candidate, is a recombinant form of an endogenous human protein, Pentraxin-2 (PTX-2), that is specifically active at the site of tissue damage. PRM-151 is an agonist that acts as a monocyte/macrophage differentiation factor to prevent and potentially reverse fibrosis. PRM-151 has shown broad anti-fibrotic activity in multiple preclinical models of fibrotic disease, including pulmonary fibrosis, acute and chronic nephropathy, liver fibrosis, and age-related macular degeneration.
Phase 1a and 1b clinical studies in healthy subjects and Idiopathic Pulmonary Fibrosis (IPF) patients have demonstrated that PRM-151 was well tolerated. Additionally, a Phase 1b study in patients with IPF showed encouraging results in exploratory efficacy endpoints, which were presented in an oral session at the 2013 Annual Meeting of the American Thoracic Society1
Myelofibrosis (MF), a type of myeloproliferative neoplasm, is a serious, life-limiting cancer that is characterized by fibrosis of the bone marrow. Replacement of the bone marrow by scar tissue prevents the normal production of blood cells, leading to anemia, fatigue, and increased risk of bleeding and infection. Production of blood cells shifts to the spleen and liver (extramedullary hematopoiesis), which become enlarged, causing severe discomfort, inability to eat, and weakness. Symptomatic myelofibrosis affects approximately 18,000 people per year in the US, with a median age of 61-66.² The only potentially curative treatment is allogeneic bone marrow transplant, which results in reversal of fibrosis and all symptoms, but is a realistic option for only a small number of patients. Other currently available therapies address the symptoms, but have minimal, if any, impact on the underlying fibrosis.
Promedior is a clinical stage biotechnology company pioneering the development of targeted therapeutics to treat diseases involving fibrosis. Fibrosis is a harmful process that occurs in many diseases, when normal healthy tissue is replaced with excessive scar tissue, compromising function and ultimately leading to organ failure. Promedior's proprietary platform is based upon Pentraxin-2, an endogenous human protein that is specifically active at the site of tissue damage and works as an agonist, preventing and potentially reversing fibrosis.
Promedior has successfully advanced its lead therapeutic candidate in human clinical trials, and is initially focused on rare fibrotic diseases, including idiopathic pulmonary fibrosis (IPF) and myelofibrosis. Promedior is backed by leading global healthcare venture investors, has a significant intellectual property estate relating to the discoveries and applications of Pentraxin-2 therapeutics and is led by an experienced management team.
