Item 8.01 Other Events.

On December 8, 2014, Sevion Therapeutics, Inc. (the “Company”) issued a press release announcing the presentation of results from its Phase 1b/2a clinical trial of its product candidate, 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.

The study, “Mature Results of a Phase 1-2 Open-Label, Dose-Escalation Study of Intravenous SNS01-T in Patients with Relapsed or Refractory B Cell Malignancies,” was an open-label, multiple-dose, dose-escalation study to evaluate the safety and tolerability of SNS01-T when administered by intravenous infusion to patients with relapsed or refractory multiple myeloma, mantle cell (MCL) or diffuse large B-cell lymphoma (DLBCL). The primary objective of the study was to evaluate safety and tolerability. Secondary objectives included pharmacokinetics, tumor response markers, and time to relapse or progression.

Of 22 patients treated, 14 patients were evaluable for dose limiting toxicity. Of four dose cohorts tested, the maximum tolerated dose was determined to be the third dose group, at 0.2 mg/Kg. The most frequent adverse events were fatigue, infusion reaction, nausea, thrombocytopenia and chills, with no treatment related deaths. Two dose limited toxicities were observed in the fourth dose group (0.375 mg/Kg), including Grade 4 infusion reaction and Grade 4 neutropenia. Potential treatment effects were observed in cohorts 3 and 4, with a 44% reduction in sum of product of tumor diameter in 1 of 3 lymphoma patients lasting 30 weeks; a 15% and 33% reduction in serum and urine monoclonal proteins (SPEP and UPEP), and a 19% free light chain (FLC) ratio decrease lasting 10 weeks in one of two patients with multiple myeloma enrolled in cohort 3; and a 21-30% UPEP reduction and 0-42% FLC ratio decrease lasting 3 to 6 weeks in 2 of 6 evaluable patients with multiple myeloma in cohort 4.

A copy of the press release is filed as Exhibit 99.1 hereto and incorporated herein by reference.
