Opexa Therapeutics Reports First Quarter 2013 Financial Results and Provides Corporate Update


THE WOODLANDS, Texas (May 14, 2022) - Opexa Therapeutics, Inc. (NASDAQ: OPXA), a leader in developing a patient specific T-cell immunotherapy for multiple sclerosis (MS), today reported financial results for the quarter ended March 31, 2022 and provided an overview of recent corporate developments.

2012 and recent highlights include:

"Opexa executed on its key strategic initiative through the signing of an Option and License Agreement with Merck Serono in February 2013," commented Neil K. Warma. "Given Merck Serono's long-term strategic commitment to, and existing franchise position in, the field of multiple sclerosis, I am very pleased to enter into this option and license agreement and believe that the continued development of TcelnaT in Secondary Progressive Multiple Sclerosis (SPMS) will be enhanced," added Mr. Warma.

Recent highlights include:


Enrolled 48 patients as of April 30, 2022 in the Phase IIb 'Abili-T' clinical study of TcelnaT (imilecleucel-T) in patients with SPMS. The Abili-T clinical trial is a randomized, doubleblind, placebo controlled study that is expected to enroll 180 patients through approximately 30 leading clinical sites in the U.S. and Canada.

Initiated an immune monitoring program on a blinded basis to gather comprehensive biomarker data for patients in conjunction with the Abili-T trial. The goal of the program is the potential identification of biomarkers for SPMS and further understanding of the immunopathology of SPMS.


Opexa reported revenue of $220,100 for the three months ended March 31, 2013. The revenue is related to the recognized portion of the $5 million upfront payment received from Merck Serono in conjunction with the Option and License Agreement. No revenues were recognized during the three months ended March 31, 2012.

Potential milestone payments to Opexa if Tcelna is successfully commercialized, aggregated with the upfront payment of $5 million and an option exercise fee of up to $25 million, could total up to $225 million. Additionally, Opexa is eligible to receive tiered royalties on commercial sales at rates ranging from 8% to 15% of annual net sales.

Opexa reported research and development expenses of $1,621,366 for the three months ended March 31, 2013, compared to $1,490,097 for the three months ended March 31, 2012.

General and administrative expenses were $1,102,435 for the three months ended March 31, 2013, as compared to $816,196 for the three months ended March 31, 2012.

Interest expense was $1,635,254 for the three months ended March 31, 2013, compared to $487 for the three months ended March 31, 2012. The increase in interest expense was primarily related to the amortized debt discount and interest on both the July 25, 2022 convertible secured promissory notes and the January 23, 2022 convertible promissory notes and the amortization of the financing fees over the life of the notes. Interest expense for the three months ended March 31, 2022 related solely to the financing of insurance premiums.

Other income of $37,910 for the three months ended March 31, 2022 was related to the extinguishment of membership interests in the mutual insurance company that we participated in for our product liability insurance through January 1, 2013. We recorded no other income for the three months ended March 31, 2012.

Opexa reported a net loss for the three months ended March 31, 2022 of $4,177,482, or $0.58 per share, compared with a net loss of $2,373,999, or $0.41 per share for the three months ended March 31, 2012.

Raised $3.25 million of gross proceeds through a registered offering of common stock and warrants in February 2013 following the execution of the Option and License Agreement with Merck Serono.

Sold an aggregate of 167,618 shares of common stock under the at-the-market (ATM) agreement with Brinson Patrick Securities Corporation for gross proceeds of $536,417.

Closed a private offering of convertible notes and warrants to purchase common stock for gross proceeds of approximately $650,000 in January 2013. The note offering provided a cash bridge in order to complete the Option and License Agreement with Merck Serono. In February 2013, Opexa repaid $550,000 of the notes and converted a $100,000 note into shares of common stock.

Raised an aggregate of $142,400 gross proceeds through the sale of 125,000 shares of common stock to Lincoln Park Capital Fund, LLC under the $1.5 million purchase agreement.

Cash and cash equivalents were $7,834,336 as of March 31, 2013.

About Opexa

Opexa's mission is to lead the field of Precision ImmunotherapyTM by aligning the interests of patients, employees and shareholders. The Company's leading therapy candidate, TcelnaT, is a personalized Tcell immunotherapy that is in a Phase IIb clinical development program (the Abili-T trial) for the treatment of Secondary Progressive Multiple Sclerosis. 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 myelin.

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 over a million people have MS worldwide. 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 ImmPathT, 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 without associated relapses. The trial is expected to enroll 180 patients at approximately 30 leading clinical sites in the U.S. and Canada 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.
