• Hires Two New Clinical Research organizations (CRO's) to accelerate patient enrollment
  • Plans to add another 60-80 clinical centers around the world
  • Ergomed Group to fund up to $10 million of clinical expenses under Co-Development Agreement

Vienna, VA, April 23, 2013 -- CEL-SCI Corporation (NYSE MKT: CVM) today provided an update on the Phase III Clinical Trial of its investigational drug Multikine* (Leukocyte Interleukin, Injection) for the treatment of head and neck cancer. The Company announced that it has hired two clinical research organizations (CRO's) who will manage the global Phase III study; Aptiv Solutions and Ergomed who are both international leaders in managing oncology trials. Both CRO's will help the Company expand the trial by 60-80 clinical sites globally. These two CRO's have replaced the current CRO managing the study. To date, the study has enrolled 117 patients and has been conducted at 39 sites in 8 countries, including three centers in Israel where CEL-SCI's partner Teva Pharmaceuticals has the marketing rights, and nine centers in Taiwan where the Company's partner Orient Europhama has the marketing rights.

Under a co-development agreement, Ergomed will contribute up to $10 million towards the study where it will perform clinical services in exchange for a single digit percentage of milestone and royalty payments, up to a specified maximum amount. Ergomed, a privately-held firm headquartered in Europe with global operations, has entered into five similar co-development agreements, including one with Genzyme (purchased by Sanofi in 2011 for over $20 billion). Ergomed will be responsible for the majority of the new patient enrollment since it has a novel model for clinical site management to accelerate patient recruitment and retention. For example, they have almost 25 physicians who can directly call on clinical sites to aid recruitment and retention. Some of the Ergomed physicians also have experience of being clinical investigators themselves. CEL-SCI believes that this interaction on a physician to physician level is what is needed to help physicians increase enrollment in the Multikine study.

"We are pleased that we have partnered with two highly experienced and committed CRO's to manage the global Phase III trial going forward," said Geert Kersten, CEL-SCI's CEO. "Each of the CRO's has assigned accomplished teams to our study. Ergomed's co-development agreement to cover up to $10 million of clinical expenses is important since Ergomed is responsible for most of the patient enrollment and patient enrollment is the rate limiting step in the study. We believe that the co-development model aligns their interests with those of CEL-SCI, leading to fast enrollment and completion of the study. The Company is also very familiar with Aptiv's capabilities, as we have worked with Aptiv on a number of projects, such as the development of the Phase III protocol. Both CRO's have a long and successful track record in oncology."

"These changes were necessary as most of the key personnel at the prior CRO who were involved in our study departed after the CRO was acquired. This had a very negative effect on study enrollment. As a result, the number of patients that have been enrolled and treated in the study fell below the level agreed to with the CRO. However, a sufficient number of patients have been enrolled to date for the trial to be assessed and pass the Independent Data Safety and Monitoring Committee (IDMC) initial safety evaluation of the study in the fall of 2012. We believe that, with the expanded number of sites and two very focused CRO's, we will be able to accelerate the enrollment process significantly and complete the Study in a timely manner."

The Multikine Phase III study is enrolling patients with advanced primary, not yet treated, head and neck cancer. The objective of the study is to demonstrate a statistically significant 10% improvement in overall survival of enrolled patients who are treated with Multikine plus Standard of Care (SOC) vs. subjects who are treated with SOC only. Multikine is intended to create an anti-tumor immune response to reduce local / regional tumor recurrence and thereby increase the survival of these patients.

CEL-SCI's lead investigational therapy Multikine, is the first immunotherapeutic agent being developed as a potential first-line treatment for advanced primary head and neck cancer. If it were to be approved by regulatory agencies (e.g. FDA) for use following completion of our clinical development program, Multikine would become an additional and different kind of therapy in the fight against cancer: one that aims to employ our body's natural ability to fight tumors.

About CEL-SCI Corporation

CEL-SCI is dedicated to research and development directed at improving the treatment of cancer and other diseases by utilizing the immune system, the body's natural defense system. Its lead investigational therapy is Multikine* (Leukocyte Interleukin, Injection), currently being studied in a pivotal global Phase III clinical trial. CEL-SCI is also investigating an immunotherapy (LEAPS-H1N1-DC) as a possible treatment for H1N1 hospitalized patients and as a vaccine (CEL-2000) for Rheumatoid Arthritis (currently in preclinical testing) using its LEAPS technology platform. The investigational immunotherapy LEAPS-H1N1-DC treatment involves non-changing regions of H1N1 Pandemic Flu, Avian Flu (H5N1), and the Spanish Flu, as CEL-SCI scientists are very concerned about the possible emergence of a new more virulent hybrid virus through the combination of H1N1 and Avian Flu, or maybe Spanish Flu. The Company has operations in Vienna, Virginia, and in/near Baltimore, Maryland.

Moreover, no definitive conclusions can be drawn from the early-phase, clinical-trials data involving the investigational therapy Multikine (Leukocyte Interleukin, Injection). Further research is required, and early-phase clinical trial results must be confirmed in the well-controlled, Phase III clinical trial of this investigational therapy that is currently in progress.
