A Pilot Study of Stereotactic Radiosurgery combined with Ipilimumab in Patients with Newly Diagnosed Melanoma Metastases in the Brain and Spine
Protocol Number:
Phase I
Michael Lim
This research is being done to look at the safety of using stereotactic radiosurgery (SRS) and Ipilimumab together to treat melanoma that has spread to the brain or spine. Both Ipilimumab and SRS are used alone for the treatment of melanoma that has spread. Standard of care uses both of these treatments but are not at the same time. By using them together, we expect better treatment of melanoma, but there might be an increase in side effects. This research study plans to look at the timing and sequence of the SRS and the Ipilumumab. There is also an option to adjust the doses of the Ipilumumab if too many side effects are seen. �Ipilimumab� is approved by the Food and Drug Administration (FDA) for the treatment of melanoma that has spread throughout the body. It works by activating your immune system to fight off cancer. �Stereotactic radiosurgery� (SRS) is approved by the FDA for the treatment of melanoma in the brain or spine. It uses radiation to treat tumors without needing to cut or use stitches. The combination of SRS and Ipilimumab in this research study is investigational. The word �investigational� means that this combination is not approved by the FDA.
Inclusion Criteria: 1. Patients must have histologically confirmed diagnosis of melanoma. The pathologic confirmation may be from another metastatic site or from metastatic brain or spine lesions. 2.Patients must have Stage IV melanoma, with newly identified brain or spine metastases. 3.Patients must have measurable lesion in the brain or spine that is greater than 3 mm seen on magnetic resonance imaging (MRI) with contrast. 4.Karnofsky Performance Scale greater than 70% 5.Patients must have normal organ and marrow function as defined below: leukocytes greater than 3,000/mcL absolute neutrophil count greater than 1,500/mcL platelets greater than 100,000/mcL total bilirubin�2X institutional upper limit of normal AST(SGOT)/ALT(SGPT) less than 2.5 X institutional upper limit of normal creatininewithin normal institutional limits OR According to Johns Hopkins MRI policy 6.Women of child bearing potential (WOCBP) using a reliable form of contraception during the study treatment period and for up to 12 weeks following the last dose of study drug. 7. Men must agree to the use of male contraception during the study treatment period and for at least 12 weeks after the last dose of study drug. 8.Ability to understand and the willingness to sign written informed consent document(s). Exclusion Criteria: 1. Prior whole brain radiation or conventional radiation to the spine at the site of new lesion. 2. Prior chemotherapy within 28 days of starting treatment. 3. Prior therapy with investigational drugs within 28 days or at least 5 half-lives (whichever is longer) before study administration. 4. Prior therapy with an anti-PD-1, anti-PD-L1, anti-PDL-2, or anti-CTLA-4 antibody. 5. Neurologic dysfunction that would confound the evaluation of neurologic and other adverse events. 6. Known allergy to compounds of similar chemical or biologic composition to ipilimumab. 7. Pregnant or breastfeeding women. 8. Known history of Human Immunodeficiency Virus. 9. Active infection requiring therapy, positive tests for Hepatitis B surface antigen or Hepatitis C ribonucleic acid (RNA). 10. Active autoimmune disease, history of autoimmune disease or history of syndrome that required systemic steroids or immunosuppressive medications. Exceptions include those with vitiligo or resolved childhood asthma/atopy. Subjects with asthma who require intermittent use of bronchodilators (such as albuterol) will not be excluded from this study. 11. Use of any vaccines against infectious diseases (e.g. varicella, influenza, etc.) up to 4 weeks (28 days) before receiving ipilimumab. 12. Prisoners or subjects who are compulsorily detained for treatment of either a psychiatric or physical (e.g. infectious disease) illness. 13. Patients with both brain and spine metastases will be excluded from the trial. 14. Patients who are allergic to MRI contrast agent or have contraindication for MRI.
This is a single institution, open label pilot study to evaluate the safety profile of standard ipilimumab in combination with SRS per standard doses among patients with newly diagnosed melanoma brain or spinal metastases. Both ipilimumab and SRS will be given according to the standard of care. Study subjects must have a baseline pre-treatment MRI within 21 days prior stereotactic radiosurgery. A cohort of six (6) patients will be treated at Dosing Schedule 1(Figure 1). If the observed dose limiting toxicity (DLT) rate is less â?¤33%, the dose cohort will be expended to a total of 15 patients. Brain and spine metastases will be evaluated as two separate cohorts. If the first schedule produces DLTs in greater than 33% of patients, the Second Dosing schedule will be implemented. If the second dosing schedule produces DLTs in greater than 33% of patients, the Third Dosing schedule will be implemented. After 6 patients were enrolled in a cohort, their safety and toxicity will be continuously monitored till 12 weeks (3 months) after the initial dose of Ipilimumab is given for evaluating dose-limiting toxicities. Patients will receive 1-5 fractions of radiosurgery at the discretion of the treating physician per standard of care, with consideration of proximity to the spinal cord itself and other critical structures.
