OUTLINE: Patients undergo excisional biopsy and continue receiving standard of care therapy for 3-4 months prior to the start of study therapy. Patients with successful generation of STIL101 for injection receive cyclophosphamide intravenously (IV) over 2 hours on days -5 to -4, fludarabine IV over 30 minutes on days -5 to -1 and STIL101 for injection IV on day 0 in the absence of disease progression or unacceptable toxicity. Patients also receive aldesleukin subcutaneously (SC) once daily (QD) on day 0 for up to 6-10 days. Additionally, patients undergo blood sample collection, biopsy, computed tomography (CT) and optional magnetic resonance imaging (MRI) throughout the study. After completion of study treatment, patients are followed up at days 42, 56, 70 and 84 then every 2-4 weeks up to week 96 or progression. Patients who discontinued treatment are followed up every 6 months.
