ROCKVILLE, Md., May 15, 2018 (GLOBE NEWSWIRE) -- Rexahn Pharmaceuticals, Inc. (NYSE American:RNN), a clinical-stage biopharmaceutical company developing innovative, targeted therapeutics for the treatment of cancer, advances its ongoing Phase 2a study of RX-3117 in combination with Abraxane® in first-line patients with metastatic pancreatic cancer following a recently completed routine Safety Monitoring Committee (SMC) review.
The SMC has confirmed that the combination of RX-3117 and Abraxane is safe and well tolerated and that the two drugs can be given in combination at the highest recommended doses for both agents which is once-daily oral administration of 700 mg RX-3117 five times per week plus once-weekly Abraxane® at 125 mg/m2 IV given on a three weeks on/one week off per four-week cycle schedule.
"This SMC recommendation allows us to enter the second stage of the trial and continue to treat patients with the maximum tolerated doses of both RX-3117 and Abraxane, which we believe may lead to better clinical outcomes," said Ely Benaim, M.D., chief medical officer of Rexahn. "Current standard of care for metastatic pancreatic cancer utilizes gemcitabine and Abraxane in combination; however, not all patients can tolerate this regimen because of unacceptable toxicities. Poor tolerability often results in dose reductions of both agents and a shortening of treatment durations. RX-3117 selectively targets cancer cells providing a potential advantage over gemcitabine."
The Phase 2a is a two-stage, open label clinical proof-of-concept study designed to evaluate the safety and efficacy of RX-3117 in combination with Abraxane in patients with metastatic pancreatic cancer who have had no prior chemotherapies for metastatic disease. The first stage was designed to determine the optimum doses of RX-3117 and Abraxane to be evaluated in the second stage. Up to 40 patients will be enrolled into the second stage of the study and the primary endpoint is progression free survival.
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 death of tumor cells. Due to the high level of over expression of UCK2 in cancer cells, 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 combination with Abraxane® (nab-paclitaxel) in first line metastatic pancreatic cancer 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. Preclinical 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 two oncology product candidates, RX-3117 and RX-5902, in Phase 2 clinical development and additional compounds in preclinical development including RX-0201.
