Multiple Sclerosis (MS), today reported financial results for the second
quarter endedJune 30, 2014and provided an overview of the Company’s recent
corporate developments.

Recent highlights include:


       *Opexa reached the 180-patient targeted enrollment in the Phase IIb
         “Abili-T” clinical study of Tcelna (imilecleucel-T) in patients with
         Secondary Progressive Multiple Sclerosis as of May 13, 2014 and
         subsequently closed enrollment with a total of 190 patients
         randomized. The Abili-T clinical trial is a randomized, double-blind,
         placebo-controlled study at approximately 35 leading clinical sites
         in the U.S. andCanada. The Company expects to report top-line
         results during the second half of 2016.


       *Reported cash and cash equivalents of$16,214,690as ofJune 30,
       *Based on the current clinical activities for the Abili-T trial, Opexa
         believes it has sufficient capital to support its current clinical
         activities for the Abili-T trial and general operations of the
         Company into the fourth quarter of 2015.

“We are pleased to close the first half of 2014 in a strong position to
continue developing Tcelna for the treatment of patients with Secondary
Progressive Multiple Sclerosis,” saidNeil K. Warma, Opexa’s President and
Chief Executive Officer. “Completion of enrollment in the Phase IIb Abili-T
trial during this past quarter represents an important milestone in the
development of our personalized immunotherapy for the Secondary Progressive MS
community. We remain committed to our goal in developing Tcelna for this
patient population.”

As ofJune 30, 2014, Opexa’s cash and cash equivalents totaled
approximately$16,214,690 and the Company’s monthly burn rate for the six
months endingJune 2014was approximately$1.2 million. Based on the current
clinical activities for the Abili-T trial, Opexa believes it has sufficient
liquidity to support its current clinical activities for the Abili-T trial and
general operations to sustain itself into the fourth quarter of 2015.

Second Quarter Financial Results

Opexa reported revenue of$307,686for the three months endedJune 30, 2014,
compared to$348,837for the three months endedJune 30, 2013. The revenue is
related to the recognized portion of the$5 millionupfront payment received
from Merck Serono in conjunction with the Option and License Agreement entered
into between Opexa and Merck Serono duringFebruary 2013.

Research and development expenses were$3,409,210 for the three months
endedJune 30, 2014, compared with $2,223,030 for the three months endedJune
30, 2013. The increase in expenses is primarily due to the increasing
enrollment of patients for the ongoing clinical trial of Tcelna in SPMS, an
increase in the procurement and use of supplies for product manufacturing and
development, and increases in the number of employees to support the ongoing
clinical trial, employee compensation expense and stock compensation expense.

General and administrative expenses for the three months endedJune 30,
2014were$967,367, compared with $750,605 for the three months endedJune 30,
2013. The increase in expense is due to increases in employee compensation and
stock compensation expenses, and was partially offset by decreases in legal
and professional fees related to financing activities.

Depreciation and amortization expenses for the three months endedJune 30,
2014were$98,658, compared with $88,898for the three months endedJune 30,
2013. The increase in expense is due to increases in depreciation for
laboratory, manufacturing and computer equipment acquired during 2013 and 2014
and leasehold improvements during 2013 and 2014 to support increased
development activities.

Opexa reported a net loss for the three months ended June 30, 2014 of
$4,163,259, or $0.15 loss per share (basic and diluted), compared with a net
loss of $2,996,430 or $0.37 loss per share (basic and diluted) for the three
months ended June 30, 2013. The increased net loss is primarily related to a
decrease in revenue and an increase in research and development expenses,
higher general and administrative expenses and higher depreciation expense for
the quarter ending June 30, 2014.

Cash and cash equivalents were$16,214,690as ofJune 30, 2014, compared
to$5,028,280as ofJune 30, 2013.

About Opexa

Opexa’s mission is to lead the field of Precision Immunotherapy™ by aligning
the interests of patients, employees and shareholders. The Company’s leading
therapy candidate, Tcelna®, is a personalized T-cell immunotherapy that is in
a Phase IIb clinical development program (the Abili-T trial) for the treatment
of Secondary Progressive MS. Tcelna is derived from T-cells isolated from the
patient’s peripheral blood, expanded ex vivo, and reintroduced into the
patients via subcutaneous injections. This process triggers a potent immune
response against specific subsets of autoreactive T-cells known to attack

About Multiple Sclerosis (MS)

Multiple Sclerosis is a chronic, inflammatory condition of the central nervous
system and is the most common, non-traumatic, disabling neurological disease
in young adults. It is estimated that approximately two million people have MS

While symptoms can vary, the most common symptoms of MS include blurred
vision, numbness or tingling in the limbs and problems with strength and
coordination. The relapsing forms of MS are the most common. The Secondary
Progressive form of MS represents about a third of the MS patient population.

About Tcelna

Tcelna® is a potential personalized therapy that is under development to be
specifically tailored to each patient’s disease profile. Tcelna is
manufactured using ImmPath®, Opexa’s proprietary method for the production of
a patient-specific T-cell immunotherapy, which encompasses the collection of
blood from the MS patient, isolation of peripheral blood mononuclear cells,
generation of an autologous pool of myelin-reactive T-cells (MRTCs) raised
against selected peptides from myelin basic protein (MBP), myelin
oligodendrocyte glycoprotein (MOG) and proteolipid protein (PLP), and the
return of these expanded, irradiated T-cells back to the patient. These
attenuated T-cells are reintroduced into the patient via subcutaneous
injection to trigger a therapeutic immune system response.

Opexa is currently conducting a Phase IIb study of Tcelna. Named “Abili-T,”
the trial is a randomized, double-blind, placebo-controlled clinical study in
patients who demonstrate evidence of disease progression with or without
associated relapses. The trial is being conducted at approximately 35 leading
clinical sites in the U.S. andCanada with each patient receiving two annual
courses of Tcelna treatment consisting of five subcutaneous injections per
year. The trial’s primary efficacy outcome is the percentage of brain volume
change (atrophy) at 24 months. Study investigators will also measure several
important secondary outcomes commonly associated with MS, including disease
progression as measured by the Expanded Disability Status Scale (EDSS),
annualized relapse rate and changes in disability as measured by EDSS and the
MS Functional Composite.
