CATALYST is a Phase 2 single-blind, placebo-controlled, proof-of-concept study in patients presenting to the emergency department More than 27,569 individuals in the U.S. died from drug overdose deaths involving cocaine in 2022; there is currently no FDA-approved product for cocaine intoxication Topline results are expected in the first half of 2025 Aug. 20, 2024 -- Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP), a fully-integrated biopharmaceutical company with marketed products and a pipeline of development candidates, today announced the first patient has been dosed in the Phase 2, single-blind, placebo-controlled, proof of concept trial of TNX-1300 (double-mutant cocaine esterase 200 mg, i.v. solution) for the treatment of acute cocaine intoxication in the emergency department (ED). TNX-1300 is a recombinant enzyme that rapidly and efficiently degrades and metabolizes cocaine in cocaine users, as demonstrated in a prior Phase 2a randomized, double-blind, placebo-controlled, laboratory-based clinical study, providing support for the use of TNX-1300 as a treatment for life-threatening cocaine intoxication.1 Tonix has been awarded a Cooperative Agreement Grant from National Institute on Drug Abuse (NIDA), part of the National Institutes of Health (NIH), to support development of TNX-1300 for the treatment of cocaine intoxication. In addition, TNX-1300 has been granted Breakthrough Therapy designation by the U.S Food and Drug Administration (FDA). “Cocaine abuse and dependence are major problems in the U.S. However, there is currently no FDA-approved treatment indicated for cocaine intoxication, a life-threatening state characterized by acute symptoms including agitation, hyperthermia, tachycardia, arrhythmias, hypertensive crisis, myocardial infarction, stroke, and seizures,” said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “In 2022, the number of overdose deaths involving cocaine reached 27,569 individuals.2 With approximately 505,000 emergency room visits annually involving cocaine use and approximately 61,000 of the visits involving detox services to treat cocaine overdose,3,4 we believe TNX-1300 has the potential to help address the morbidity and mortality caused by cocaine intoxication. By targeting the cause rather than the symptoms of cocaine intoxication, TNX-1300 may offer significant advantages to the current standard of care for cocaine overdose.” The Phase 2 trial is a single-blind, open-label, placebo-controlled, randomized study comparing the safety of a single 200 mg dose of TNX-1300 to placebo injection plus standard of care alone for the treatment of signs and symptoms of acute cocaine intoxication. The study is being conducted in the EDs of six academic medical centers in the U.S. It will include approximately 60 subjects presenting to the ED with cocaine intoxication. During the treatment period, subjects randomized to receive TNX-1300 will receive a single i.v. injection of TNX-1300 administered over two minutes or less; whereas subjects randomized to receive standard of care alone will receive a single i.v. saline injection over two minutes or less. For both study arms, signs and symptoms of cocaine intoxication will be assessed at pre-determined time points after treatment. After randomization, blood samples will be drawn at specific time points to assess the pharmacokinetics of TNX-1300 and levels of cocaine and its metabolites in the plasma. The primary endpoint of the study is reduction of systolic blood pressure associated with acute cocaine intoxication identified at study baseline comparing TNX-1300 to placebo with standard of care after 60 minutes. A variety of secondary endpoints will be measured, including reduction of circulating cocaine and levels of its metabolites at multiple post-baseline timepoints. TNX-1300 (T172R/G173Q double-mutant cocaine esterase 200 mg, i.v. solution) is being developed under an Investigational New Drug application (IND) for the treatment of cocaine intoxication. TNX-1300 is a recombinant protein enzyme produced through recombinant DNA technology in a non-disease-producing strain of E. coli bacteria. Cocaine esterase (CocE) was identified in bacteria (Rhodococcus) that uses cocaine as its sole source of carbon and nitrogen and that grows in soil surrounding coca plants.5 The gene encoding CocE was identified and the protein was extensively characterized.5-8 CocE catalyzes the breakdown of cocaine into metabolite ecgonine methyl ester and benzoic acid. Wild-type CocE is unstable at human body temperature, so targeted mutations were introduced in the CocE gene and resulted in the T172R/G173Q double-mutant CocE, which is active for approximately 6 hours at body temperature.8 In a Phase 2 laboratory-based study in volunteers who use cocaine, TNX-1300, at 100 mg or 200 mg i.v. doses, was well tolerated and rapidly reduced cocaine effects after cocaine 50 mg i.v. challenge.1 Cocaine is an illicit recreational drug which is taken for its pleasurable effects and associated euphoria. In 2022, over 5 million individuals in the U.S. reported current cocaine use, almost 2% of the population.9 Pharmacologically, cocaine blocks the reuptake of the neurotransmitter dopamine from central nervous system synapses, resulting in the accumulation of dopamine within the synapse and an amplification of dopamine signaling and its capacity to produce euphoric mood states. With the continued use of cocaine, however, intense cocaine cravings occur resulting in a high potential for abuse and addiction (dependence), as well as the risk of acute cocaine intoxication. Cocaine intoxication refers to the deleterious effects on several body systems, especially those involving the cardiovascular system. Common symptoms of cocaine intoxication include tachyarrhythmias and elevated blood pressure, either of which can be life-threatening. As a result, individuals with known or suspected cocaine intoxication are sent immediately to the emergency department (ED), preferably by ambulance in case cardiac arrest occurs during transit. The standard of care for treating cocaine intoxication in the ED focuses on symptom management, preventing complications, and supporting cardiovascular, respiratory, and neurological function, e.g. benzodiazepines for agitation, seizures, and sympathetic overdrive; antihypertensives for extremely elevated blood pressure; aspirin and nitroglycerine for cardiac ischemia. There are approximately 505,000 emergency room visits for cocaine abuse each year in the U.S., of which 61,000 require detoxification services.3,4 According to the National Institute on Drug Abuse, in 2022 the number of overdose death involving cocaine reached 27,569 individuals.2 In 2019, Black Americans experienced the highest death rate for overdoses involving cocaine, at 10.7 per 100,000.10 References 1 Nasser et al.
