A Beta-only IL-2 ImmunoTherapY Study

Exclusion criteria

A 1-week washout is required for palliative radiation (\<2 weeks of radiotherapy) to non-CNS disease. • Radiation therapy to the lung that is \> 30Gy within 6 months prior to start of treatment. • Currently participating in or has participated in a study of an investigational agent or has used an investigational device within 4 weeks prior to start of treatment. Concomitant participation in an observational study must be discussed on a case-by-case basis with the MM for approval. 2. Has known active CNS metastases and/or carcinomatous meningitis. Patients with previously treated brain metastases may participate provided they are radiologically stable, i.e., without evidence of progression for at least 4 weeks by repeat imaging (note that the repeat imaging should be performed during study screening), clinically stable and without requirement of steroid treatment for at least 14 days prior to start of treatment, subject to discussion with MM. 3. Active malignancy (other than the disease under treatment in the study) within the previous 3 years except for curable cancers. 4. Condition requiring long-term systemic treatment with either corticosteroids \> 10 mg daily prednisone equivalent or any other form of immunosuppressive therapy within 7 days prior to start of treatment. 5.

Any other underlying medical conditions that, in the Investigator's opinion, will make the administration of study drug(s) unsafe or obscure the interpretation of toxicity determination or adverse events. 13. Known severe hypersensitivity to any component of study drug(s). 14. Inability to comply with study and follow up procedures as judged by the Investigator.
