Exhibit 99.1

Sevion Therapeutics Reports Second Quarter 2015 Financial Results

San Diego, CA – February 18, 2014 - Sevion Therapeutics, Inc. ("Sevion" or the "Company") (OTCQB: SVON), a biopharmaceutical company which discovers, develops and acquires next-generation biologics for the treatment of cancer and immunological diseases, today reported financial results for the fiscal quarter ended December 31, 2014 (“Second Quarter 2015”).

Sevion has been advancing its SVN001 product candidate through preclinical development where it has demonstrated potent activity as well as advancing its SVN002 product candidate through preclinical development. However, given the Company’s limited capital resources, in December 2014, the Company decided to temporarily reduce its research and development spending on its antibody program until it is able to consummate a strategic transaction or a financing transaction. Efforts are underway to accomplish this objective.

Fiscal Second Quarter 2015 and Recent Highlights

· Announced collaboration agreement with CNA Development, LLC. In December, Sevion announced a collaboration agreement with CNA Development, LLC, an affiliate of Janssen Pharmaceuticals, Inc. (Janssen) to discover antibodies using Sevion’s spatially addressed library platform. The collaboration facilitated by the Johnson & Johnson Innovation center in California will include discovery of antibodies against multiple targets in several therapeutic areas. Sevion and Janssen will jointly conduct research on antibodies discovered by Sevion, and Janssen will have an option to an exclusive license to develop, manufacture, and commercialize candidates resulting from the collaboration.

· Presented Results of SNS01-T Phase 1b/2a Dose Escalation Study at ASH Annual Meeting. In December, the Company presented of results from the Company’s Phase 1b/2a clinical trial of SNS01-T for the treatment of multiple myeloma and lymphoma. The results were presented in a poster session titled “Lymphoma: Therapy with Biologic Agents, excluding Pre-Clinical Models: Poster III” at the 56^th American Society of Hematology (ASH) Annual Meeting and Exposition in San Francisco.

Second Fiscal Quarter 2015 Financial Results

The Company reported no revenue for the Second Quarter 2015 and Second Quarter 2014.

Research and development expenses for the Second Quarter 2015 were $1.4 million compared to $0.7 million for the Second Quarter 2014. The increase was primarily due to the acquisition of Fabrus, Inc., in May 2014.

General and administrative expenses were $1.3 million for the Second Quarter 2015 compared to $0.9 million for the comparable year-ago second quarter. The increase was primarily due to severance payments due to terminated employees and legal fees as a result of closing the New Jersey office and suspending the Factor 5a program. This was partially offset by a decrease in stock-based compensation.

During the Second Quarter 2015, due to the decline of the Company’s market value, the Company recorded an impairment to goodwill in the amount of $8.1 million.

The loss applicable to common shares for the Second Quarter 2015 was $10.8 million, or $(0.78) per share, compared with a loss applicable to common shares for the Second Quarter 2014 of $1.6 million, or $(0.48) per share. This increase in the loss applicable to common shares was primarily the result of the impairment of goodwill, and an increase in research and development expenses and general and administrative expenses.

As of December 31, 2014, the Company had cash and cash equivalents of $2.1 million, compared to cash and cash equivalents of $6.1 million as of June 30, 2014. The Company believes that it has sufficient funds to maintain operations through March 2015.
