Duet Therapeutics Integrates Immunotherapy Assets of Scopus and Olimmune, Acquired by Scopus in June 2021 Integration Creates Comprehensive, Industry-Leading Portfolio of Bi-Functional Cancer-Targeting Oligonucleotides NEW YORK, Sept. 02, 2021 (GLOBE NEWSWIRE) -- Scopus BioPharma Inc. (Nasdaq: “SCPS”), a clinical-stage biopharmaceutical company developing transformational therapeutics for serious diseases with significant unmet medical need, today announced the launch of Duet Therapeutics. Duet Therapeutics integrates the management and clinical development of the immunotherapy assets of Scopus and Olimmune, acquired by Scopus in June 2021. Duet is a wholly-owned subsidiary of Scopus. Joshua R. Lamstein, Chairman of Scopus, stated, “We are extremely excited to announce the launch of Duet Therapeutics. The integration of the immuno-oncology assets of Scopus and Olimmune creates a comprehensive, industry-leading portfolio of bi-functional cancer-targeting oligonucleotides. Our highly complementary IP-protected technologies all target STAT3 inhibition. We believe our oligonucleotide technologies are unique, highly differentiated and superior to other STAT3 inhibitors currently under development.” Alan Horsager, Ph.D., President and Chief Executive Officer of Duet and President — Immuno-Oncology for Scopus, stated, “Overseeing the integration and clinical development of Duet’s immuno-oncology platform is an extraordinary opportunity. It is a privilege to play a key role in integrating and developing Duet’s drug candidates. Based on the large body of scientific data, we firmly believe our oligonucleotide platform has enormous potential to address one of society’s most significant unmet medical needs — unprecedented treatments, and potentially cures, for many different types of cancer. I can think of no greater professional mission than creating new standards of care, improving patient outcomes and saving lives.” The Duet Platform is comprised of three complementary, underpinning technologies: • RNA silencing CpG-STAT3siRNA (“DUET-01”) • Antisense CpG-STAT3ASO (“DUET-02”) • Protein degradation CpG-STAT3decoy (“DUET-03”) Dr. Horsager added, “The unique mechanism-of-action of these synthetic oligos comes from simultaneously targeting two intracellular immune pathways, STAT3 and TLR9. The targeted inhibition of STAT3, a master immune checkpoint inhibitor, reawakens immune cells and allows for the full potential of TLR9-driven immune responses.” DUET-01 is in a Phase 1 clinical trial, as a monotherapy, for B-cell non-Hodgkin lymphoma. In 2022, Duet is targeting to INDs for DUET-02 in two separate indications: genitourinary and head & neck cancers. Duet is also evaluating combination therapies with checkpoint inhibitors. About Scopus BioPharma Scopus BioPharma Inc., both directly and through subsidiaries, is a clinical-stage biopharmaceutical company developing transformational therapeutics for serious diseases with significant unmet medical need. The company’s lead drug candidate is a novel, targeted immuno-oncology RNA therapy for the treatment of multiple cancers. This drug candidate is highly distinctive, encompassing both RNA therapy and immunotherapy by synthetically linking siRNA to an oligonucleotide TLR9 agonist, creating the potential for targeted gene silencing with simultaneous TLR stimulation and immune activation in the tumor microenvironment. Additional STAT3-targeting immunotherapy drug candidates include bi-functional antisense and protein degradation therapies. In addition, the company is developing additional drug candidates that target the endocannabinoid system, including MRI-1867 for the treatment systemic sclerosis. The company also seeks to identify additional compelling technologies for potential acquisition, in-licensing and/or other similar transactions.

MONTREAL--(BUSINESS WIRE)-- Inversago Pharma Inc. (“the Company” or “Inversago”), the peripheral CB1 blockade company, today announced the U.S. Food and Drug Administration (FDA) granted a Rare Pediatric Disease (RPD) designation to the Company’s lead compound, INV-101, for the treatment of Prader-Willi syndrome (PWS). A Phase I study with INV-101 is currently ongoing to evaluate its safety, tolerability and pharmacokinetics profile. “The RPD designation is an important recognition for Inversago, highlighting the potential role of our lead program in the treatment of young patients affected by Prader-Willi syndrome,” stated François Ravenelle, PhD, CEO and founder of Inversago Pharma. “As a consequence of this genetic disorder, PWS patients have an overactivated endocannabinoid system, which leads to excessive weight gain, hyperphagia and neurodevelopmental symptoms. As such, developing safe, peripherally-acting inverse agonists of CB1 receptors offers the potential to address many of their significant and unmet medical needs,” added Glenn Crater, MD, CMO of Inversago Pharma. The RPD designation is open to drug development programs targeting serious, life-threatening diseases that primarily affect less than 200,000 Americans aged 18 or younger. Once a new drug application is approved under this program, the company is eligible to receive a priority review voucher for any related marketing application. Such a voucher may also be sold or transferred. About Prader-Willi Syndrome Prader-Willi syndrome (PWS) is a genetic disorder affecting equally male and female newborns, notwithstanding geographical origin, and occurring in about one out of 15,000 births. PWS is considered as the most common genetic cause of life-threatening childhood obesity. At an early stage, PWS is characterized by weak muscle tone (hypotonia), feeding difficulties, poor growth, and delayed development. As the disorder progresses, affected children develop an insatiable appetite, which leads to chronic overeating (hyperphagia) and obesity, among other symptoms. The treatment of PWS is currently limited to managing symptoms of the disorder as they arise. To date, there is no cure or disease modifying treatment for this genetic disorder. About INV-101 INV-101 is a first-in-class, small molecule CB1 inverse agonist / antagonist being developed by Inversago for the treatment of PWS and non-alcoholic steatohepatitis (NASH). It is specifically designed to interact with peripheral CB1 receptors located in the gastro-intestinal tract, liver, pancreas, adipose tissues, muscles, lungs and other organs, thus aiming for a safe and effective therapeutic approach without the known liabilities of centrally-acting CB1 blockers. The peripheral CB1 blockade is a well-documented pathway, linked to many clinically meaningful metabolic benefits. About Inversago Pharma Inversago Pharma is a clinical-stage, biotech company specialized in the development of new therapies focusing on CB1 blockade, based on first-in-class, peripherally-acting, CB1 inverse agonists. The Company aims to provide new treatment options that improve the lives of patients affected by metabolic conditions such as PWS, NASH, type 1 diabetes (T1D) and diabetic nephropathy.
