CEL-SCI Corporation Releases Letter to Shareholders

The following letter is being released by CEL-SCI Corporation (NYSE MKT:CVM) to its shareholders:

Dear Fellow Shareholders:

We are giving you an update on clinical hold communications with the U.S. Food and Drug Administration (FDA), the “Agency”, regarding the previously announced partial clinical hold of CEL-SCI's Phase 3 clinical trial of its investigational drug Multikine* (Leukocyte Interleukin, Injection) in patients with squamous cell carcinoma of the head and neck.

The partial clinical hold on this ongoing Phase 3 head and neck cancer trial with 928 patients enrolled covered a range of issues previously described to the shareholders. Following a Type A meeting with the FDA in February 2017, we filed a response that was intended to address all of these issues in April, 2017. As part of our response to address the FDA concerns expressed in item 3 of the October 15, 2016 letter from the FDA to us, we submitted a proposed update to the Investigator’s Brochure (IB) and a proposed “Dear investigator” letter which we planned to distribute following the FDA’s review and approval. In its most recent communication in May 2017, the FDA stated: “We have completed the review of your April 19, 2017, submission and have concluded that removal of the clinical hold is not warranted since item 3 of the October 15, 2016 letter has not been resolved. In addition, we have identified new deficiencies in your April 19, 2017, submission.” The FDA directed that: 1) The IB and the “Dear investigator” letter should contain specific statements and data which were not included in the proposed texts we had submitted in April 2017 and 2) Some of the statements that were included in the proposed texts accompanying our April 2017 response should be removed. Work on revising the IB and the “Dear investigator” letter in accordance with the FDA’s directions has already begun and we hope to resubmit the amended documents to the FDA for their review and approval very soon. We are hopeful that the FDA will consider the amended documents satisfactory and will consider lifting the clinical hold.

In the Agency’s May 2017 letter, the FDA also stated: “Until you have submitted the required information and we notify you that you may initiate clinical studies, this IND remains on clinical hold and you may not legally initiate or resume clinical studies under it.” The heading on the FDA May 2017 letter is “Continue Full Clinical Hold”, whereas the heading on previous hold letters was “Partial Clinical Hold”. The FDA communicated to us that the IND is on Full Clinical Hold because the exception to the full hold (Patients enrolled in our Phase 3 head and neck cancer protocol prior to September 26, 2016, may continue to receive protocol-specified treatment at the discretion of the treating physician) no longer exists, since all patients had completed planned treatment with our investigational product, Multikine. Placing the IND on full hold does not result in termination of the Phase 3 head and neck cancer trial and all protocol-specified data collection will continue as described in the protocol, but we may not enroll new patients and may not resume investigational product (Multikine) dosing in any previously enrolled patient. In the Agency’s May 2017, letter, the FDA stated, “Finally, since there are no patients currently receiving Multikine under this IND and the only study being conducted under this IND (Study CA001P3) is closed to accrual, we have concluded that all studies covered by this IND must be placed on clinical hold; proposed studies may not be initiated, and ongoing studies are suspended.” It should be noted that, at present, CEL-SCI is not conducting other studies with Multikine under this IND other than the ongoing Phase 3 study which is subject to the clinical hold, no other studies are planned in the immediate future, and an amendment to the Phase 3 head and neck cancer study will be filed only if required. Our study investigating the use of Multikine as a potential treatment in HPV related disease is being conducted under a different IND.

We are continuing to work extremely hard to bring our Phase 3 trial to a successful conclusion, to have the FDA's clinical hold lifted, and to win the arbitration case against the former CRO that originally ran our Phase 3 trial.

We thank you for your continued support of the Company.

Sincerely,

Geert Kersten
Chief Executive Officer
