Patients in remission are being followed for response duration and outcomes, and new patients continue to enroll into the study. In addition, ongoing Phase 1/2 trials with SL-401 are currently enrolling patients with additional malignancies including acute myeloid leukemia (AML) in remission with high risk for relapse and myeloproliferative neoplasms (MPN) of unmet medical need. A Phase 2 trial with SL-701, an immunotherapy designed to activate the immune system to attack tumors, is currently enrolling adult patients with second-line glioblastoma multiforme (GBM). SL-801, a novel oral small molecule reversible inhibitor of XPO1, is currently enrolling patients in a Phase 1 clinical trial in advanced solid tumors.
