Additional Relevant Details “The treatment paradigm in metastatic melanoma was transformed during the course of 2015 by the accelerating adoption of multiple immune checkpoint inhibitors used as monotherapy and in combination treatments. These new drugs have significantly improved outcomes in metastatic melanoma and therefore have altered the opportunity for a monotherapy such as CLBS20 in a landscape that is quickly converting to combination therapies. Therefore, we have concluded that, as designed, our current program in metastatic melanoma will not optimally leverage this asset and we will therefore discontinue the ongoing Phase 3 clinical study with CLBS20 as a monotherapy for the treatment of recurrent Stage III or Stage IV metastatic melanoma. As a result, we will reduce associated staff by approximately 40 employees at our Irvine, California facility. That said, we continue to believe in the potential of CLBS20 as a life-prolonging immunotherapeutic and will pursue licensing or partnership opportunities for its continued development as part of a combination therapy and in different oncology indications. The emphasis will be on collaborating with a company that will allow us to exploit the novel antigen presentation and T cell activation approach of CLBS20.”
