The Phase 2a clinical trial is a multicenter, open-label single-agent study of RX-3117 conducted at 5 clinical centers in the United States. Patients initially received a 700 mg daily oral dose of RX-3117, five times weekly on a three weeks on, one week off dosing schedule in a 28 day cycle for up to eight treatment cycles, or until their disease progressed. The dosing was increased to four weeks continuous treatment with no rest week for patients for whom RX-3117 was well tolerated. The primary endpoints are an assessment of the progression free survival rate or an objective clinical response and reduction in tumor size.The interim data from the Phase 2a clinical trial of RX-3117 in advanced bladder cancer was presented on Friday February 9, 2018 in a poster presentation entitled RX-3117, an Oral Hypomethylating agent to Treat Advanced Solid Tumors: Interim Results from an ongoing Phase 2a study in Advanced Urothelial Cancer (aUC). A copy of the ASCO GU poster can be viewed on the company's website at https://rexahn.com/cms/media-center/publication/posters/ About RX-3117 RX-3117 is a novel, investigational, oral, small molecule nucleoside compound. Once intracellularly activated (phosphorylated) by UCK2, it is incorporated into the DNA or RNA of cells and inhibits both DNA and RNA synthesis, which induces apoptotic cell death of tumor cells. Because UCK2 is overexpressed in multiple human tumors, but has a very limited presence in normal tissues, RX-3117 offers the potential for a targeted anti-cancer therapy with an improved efficacy and safety profile. RX-3117 is currently being studied in a Phase 2a clinical trial in in combination with Abraxane® (nab-paclitaxel) in first line metastatic pancreatic patients and a Phase 2a clinical trial in patients with advanced or metastatic bladder cancer. It has received Orphan Drug designation for the treatment of pancreatic cancer. Additional information on RX-3117 can be found at: https://rexahn.com/cms/portfolio/rx-3117/. About Rexahn Pharmaceuticals, Inc. Rexahn Pharmaceuticals Inc. (NYSE American:RNN) is a clinical stage biopharmaceutical company dedicated to developing novel, targeted therapeutics for the treatment of cancer. The company's mission is to improve the lives of cancer patients by developing next generation cancer therapies that are designed to maximize efficacy while minimizing the toxicity and side effects traditionally associated with cancer treatment. Rexahn's product candidates work by targeting and neutralizing specific proteins believed to be involved in the complex biological cascade that leads to cancer cell growth. Pre-clinical studies show that certain of Rexahn's product candidates may be effective against multiple types of cancer, including drug resistant cancers, and difficult-to-treat cancers, and others may augment the effectiveness of current FDA-approved cancer treatments. The company has a broad oncology pipeline that includes three anti-cancer compounds currently in clinical development: RX-5902 (Supinoxin™), RX-3117, and RX-0201 (Archexin ®), and a novel nanopolymer-based drug delivery platform technology that may increase the bio-availability of FDA-approved chemotherapies.

Uncertainties and risks may cause Rexahn's actual results to be materially different than those expressed in or implied by Rexahn's forward-looking statements. For Rexahn, particular uncertainties and risks include, among others, understandings and beliefs regarding the role of certain biological mechanisms and processes in cancer; drug candidates being in early stages of development, including clinical development; the ability to initially develop drug candidates for orphan indications to reduce the time-to-market and take advantage of certain incentives provided by the U.S. Food and Drug Administration; the ability to transition from our initial focus on developing drug candidates for orphan indications to candidates for more highly prevalent indications; and the expecting timing of results from our clinical trials. More detailed information on these and additional factors that could affect Rexahn's actual results are described in Rexahn's filings with the Securities and Exchange Commission, including its most recent annual report on Form 10-K and subsequent quarterly reports on Form 10-Q.
