Partnerships

Memorial Sloan Kettering Cancer Center (MSKCC)In September 2014, SELLAS announced an exclusive global collaboration and exclusive license agreement with Memorial Sloan Kettering Cancer Center (MSKCC) for the development, marketing and commercialization of MSKCC’s proprietary WT1 cancer immunotherapy.

WT1 is over-expressed in many human cancers, including most blood cancers and many solid tumors, including mesothelioma, and cancers of the ovary, lung, gastrointestinal tract, breast, and prostate. The National Cancer Institute recently ranked WT1 as the top target for cancer immunotherapy. MSKCC researchers have already shown the potential of this immunotherapy to safely immunize patients against the WT1 antigen in several clinical trials.

GPS plus nivolumab (MPM)
An investigator-sponsored trial (IST) was conducted with GPS in combination with nivolumab (Opdivo®; BMS). This Phase 1/2 clinical trial was an open label, single-center, investigator-sponsored, 10 patient study enrolling patients with ovarian cancer who relapsed at least once and returned to complete clinical remission after additional (first or subsequent) salvage chemotherapy.

An IST is being conducted with GPS in combination with nivolumab in patients with malignant pleural mesothelioma (MPM) at MSKCC. Enrollment is ongoing in this Phase 1 open-label clinical study of GPS in combination with nivolumab in patients with MPM who harbor relapsed or refractory disease after having received frontline standard of care multimodality therapy.
