VTEs without hemodynamic compromise, treated with stable doses of anticoagulants are allowed.\n* Presence of clinically significant CNS pathology:\n\n  * seizure disorder, aphasia, stroke, severe brain injuries, dementia, Parkinson's disease, or cerebellar disease. History of these disorders requires discussion with the medical monitor.\n  * Presence of clinically active psychosis.\n  * Known brain metastases unless asymptomatic and not requiring steroids for at least 2 weeks prior to the first dose of any study drug administration.\n* Active systemic autoimmune disease or any other condition that requires, or is anticipated to require, systemic treatment with steroids or other systemic immunosuppressive agents, or participants who have received such agents within 4 weeks of leukapheresis and ML261 administration (further details provided in protocol body).\n* Evidence of interstitial lung disease (such as idiopathic pulmonary fibrosis) or active pneumonitis of any etiology requiring treatment.\n* Any active infection (defined as symptoms, signs, or radiographic) of bacterial, viral, or fungal or unknown etiology requiring systemic therapy within 14 days of leukapheresis.
