Safe Harbor Statement
The statements that follow (including projections and business trends) are forward-looking
statements. Rexahn's actual results may differ materially from anticipated results, and
expectations expressed in these forward-looking statements, as a result of certain risks and
uncertainties, including Rexahn's lack of profitability, the need for additional capital to
operate its business to develop its product candidates; the risk that Rexahn's development
efforts relating to its product candidates may not be successful; the possibility of being unable
to obtain regulatory approval of Rexahn's product candidates; the risk that the results of
clinical trials may not be completed on time or support Rexahn's claims; demand for and
market acceptance of Rexahn's drug candidates; Rexahn's reliance on third party researchers
and manufacturers to develop its product candidates; Rexahn's ability to develop and obtain
protection of its intellectual property; and other risk factors set forth from time to time in our
filings with the Securities and Exchange Commission. Rexahn assumes no obligation to update
these forward-looking statements.

Rexahn: Revolutionizing the Treatment of Cancer
Identify novel drug targets which are specific to cancer cells:
  Increased efficacy, reduced toxicity
  Efficacy against multiple drug resistant cancer cells
  Synergism with existing cytotoxic compounds
Develop in-licensed targeted drug delivery platforms:
  Nano-Polymer-Drug Conjugate System (NPDCS) combines existing
 anticancer agents with a polymer/signaling moiety which directs the
 drug directly to the tumor
  Lipid-Coated Albumin Nanoparticle (LCAN) to enhance delivery of
 oligonucleotides

Supinoxin: Mechanism of action
n Phosphorylated p68 is highly
 expressed in cancer cells but not in
 normal cells, and upregulates
 cancer-related genes
n Supinoxin selectively inhibits
 phosphorylated p68 RNA Helicase
  Decreased proliferation/growth
 of cancer cells
  Synergism with cytotoxic agents
  Activity against drug resistant
 cancer cells
Cancer cell Proliferation/Tumor growth

RX-3117: Compelling Efficacy in Animal Models
13
RX-3117 has shown robust anti-tumor effects across a broad variety
of tumor types in animal models (Colon, Non-Small Cell Lung, Small
Cell Lung, Pancreatic, Renal, Ovarian and Cervical)
 
 

 
RX-3117: Compelling Efficacy in Animal Models
14
RX-3117 offers significant benefits based on overall-survival via oral
administration in nude mice
 
 

 
15
RX-3117: Efficacy in Gemcitabine-Resistant Cell Lines
The efficacy of RX-3117 was examined in 12 different human tumor
(Colon, Non-Small Cell Lung, Small Cell Lung, Pancreatic, Renal,
Ovarian and Cervical)
 
 

 
16
RX-3117: Exploratory Phase I clinical Trial (Completed)
n Exploratory Phase I clinical trial in cancer patients was conducted in Europe in 2012
n Objectives:
  Evaluate oral bioavailability and pharmacokinetics
  Assess safety and tolerability
n Drug administration cohorts:
  20 mg IV (n=3)
  50 mg oral (n=3)
  100 mg oral (n=3)
n Results:
  Nine subjects, ages 47 to 67 years, were enrolled
  RX-3117 was orally bioavailable with Tmax of 2-3 hours, T1/2 of 14-21 hours, and
 oral bioavailability of 33 to 56%
  RX-3117 was well tolerated with no post-dose adverse events, laboratory
 abnormalities, or ECG changes emerging through 7 days of follow-up
 
 

 
17
RX-3117: Phase Ib Study Design (ongoing)
n Initiated December 2013
n Cancer patients with solid tumors
n Up to 30 patients and three clinical sites
n Treatment cycle is 28 days
  Dosing 3 times a week for 3 weeks followed by 1 week off
n Dose Finding Study Design
  Escalation decisions based on safety, dosing, PK, laboratory, etc
  Patients may receive up to 8 cycles of treatment
  Anti-tumor activity secondary endpoint
  Patients will be scanned (CT or MRI) prior to initiating treatment and after every 2
 cycles
 
 

 
Archexin®
 
 

 
 
 

 
20
Archexin: Phase I Clinical trial (completed)
n Phase I objective
  To determine maximum tolerated dose, safety and pharmacokinetic profiles
n Phase I results:
  MTD was 250 mg/m2/d in Patients with an advanced cancer after up to two cycles
 of treatment
  The dose limiting toxicity was Grade 3 fatigue; no significant hematological
 abnormalities
n Phospho-Akt1 being developed as a clinical biomarker

21
Archexin: Phase IIa Study in Metastatic
Pancreatic Cancer (completed)
 § Open label 2-stage study to assess the safety and efficacy of Archexin in
 combination with gemcitabine
 § 31 subjects enrolled (10 for safety, 21 for efficacy) with ages ranging 18-65 years
 with metastatic pancreatic cancer
 § Archexin in combination with gemcitabine provided a median survival of 9.1
 months compared to the historical survival data of 5.65 months (Burris et al., 1997,
 J. Clin Oncol 15:2403) for standard single agent gemcitabine therapy
