— Novel Selective Effector Cell Activator (SECA™) Protein Designed for Targeted IL-2 Receptor Activation to Enhance Tumor-Killing Immune Cells —
The phase 1 study will be conducted in two stages: a dose-escalation stage followed by a dose-expansion stage. In the first stage of the study, ALKS 4230 will be administered as an intermittent intravenous infusion with ascending doses in patients with solid tumors who are refractory or intolerant to established therapies. This first stage of the study is designed to determine a maximum tolerated dose, and to identify the optimal dose range of ALKS 4230 based on measures of immunological-pharmacodynamic effects. Following the identification of the optimal dose range of ALKS 4230 in the first stage of the study, the dose-expansion stage of the study will evaluate ALKS 4230 in patients with selected solid tumor types. Initial results from the first stage of the phase 1 study are expected in 2017.
“ALKS 4230 is a unique immuno-oncology candidate that is designed to
harness the IL-2 mechanism in a selective way that enhances
tumor-killing immune cells, so that a patient’s own immune system can be
activated in order to fight cancer more effectively,” said
About ALKS 4230 and the SECA™ Immuno-Oncology
Program
ALKS 4230 is a novel selective effector cell
activator (SECA™) protein designed to preferentially bind and signal
through the intermediate affinity interleukin-2 (IL-2) receptor complex,
thereby selectively activating and increasing the number of
immunostimulatory tumor-killing immune cells while avoiding the
expansion of immunosuppressive cells that interfere with anti-tumor
response. The selectivity of ALKS 4230 is designed to leverage the
proven anti-tumor effects while overcoming limitations of existing IL-2
therapy which activates both immunostimulatory and immunosuppressive
receptors.
SECA proteins are engineered using Alkermes’ proprietary PICASSOTM circular permutation technology leveraging human protein biology to achieve their unique mechanism of action.
