Item 8.01 Other Events.

 

On December 10, 2013, Senesco Technologies, Inc. (“Senesco” or the “Company”) issued a press release announcing the results of preclinical studies with SNS01-T at the 55th American Society of Hematology Annual Meeting in New Orleans.

 

Senesco’s drug candidate, SNS01-T, which is the subject of an on-going Phase 1b/2a clinical study in B-cell cancers, induces cell death in cancer cells by reducing the levels of a protective protein and replacing it with a protein that induces cell death. The drug candidate was taken up more efficiently by malignant B-cells than normal human B-cells in non-clinical studies. Although 50% of normal B-cells took up SNS01-T, it did not cause cell death in the healthy cells, whereas cell death was readily seen in human myeloma cells.

 

Laboratory studies have already shown that, due to its design, SNS01-T does not produce significant levels of the message that makes the death-inducing protein in normal tissues including heart and liver. The new discoveries provide evidence suggesting SNS01-T may not affect normal human B-cells, which are an important protective component of the body’s immune system. This is in contrast to existing B-cell cancer therapies like rituximab, which is widely used in mantle cell and diffuse large cell lymphomas.

 

The study is an open-label, multiple-dose, dose-escalation study to evaluate the safety and tolerability of SNS01-T when administered by intravenous infusion to approximately 15 relapsed or refractory multiple myeloma and B-cell lymphoma patients. While the primary objective is to evaluate safety and tolerability, the effect of SNS01-T on tumor response and time to relapse or progression is assessed using multiple well-established metrics including measurement of monoclonal protein in multiple myeloma and CT imaging in B-cell lymphomas.

 

In the study patients are dosed twice-weekly by intravenous infusion for six weeks followed by an observation period. The first and second cohorts of patients received 0.0125 mg/kg and 0.05 mg/kg per dose, respectively. The third cohort received 0.2 mg/kg and the planned dose level for cohort 4 is 0.375 mg/kg, which is 30 fold higher than the starting dose in group 1. It is expected that the study will enroll six to nine patients to complete cohort 4.
