Clinical Trial Summary

Background: Mesothelioma is a type of cancer. It originates in cells that line human body cavities. Most people have advanced disease when they are diagnosed. Researchers want to see if a combination of drugs can help. Objective: To find a safe dose of LMB-100 in combination with ipilimumab when LMB-100 is injected into tumors. Eligibility: Adults ages 18 and older with malignant pleural or peritoneal mesothelioma, that cannot be cured with surgery and has not responded to standard first-line treatments for mesothelioma. Design: Participants will be screened with: - Tumor biopsy or effusion, if needed - Medical history - Physical exam - Blood and urine tests - Imaging scans - Heart and lung function tests - Pregnancy test, if needed Some screening tests will be repeated during the study. Participants will get LMB-100 on Days 1 and 4 for up to 2 cycles. Each cycle lasts 21 days. They will stay in the hospital for about 8 days each time they get LMB-100. It will be injected into their tumor with needles. Participants will get ipilimumab through a tube that is put in a vein. It will be given on Day 2 of the first 2 cycles and Day 1 of the next 2 cycles. Participants will be assessed for how well they do daily activities. They will give blood and tissue samples for research. Participants will have a safety visit 4 to 6 weeks after the last dose of the study drugs. Then they will have scans every 6 weeks until their disease gets worse. If their tumor gets bigger, they will have phone, video, or email follow-ups every 12 weeks. Participants will be on this study for life....


Description:

Background: LMB-100, and a closely related immunotoxin, SS1P, also targeting mesothelin, given intravenously, have been studied in Phase 1 clinical studies for mesothelioma and pancreatic cancer. LMB-100 given intravenously results in systemic inflammation in patients, but as a single agent has limited anti-tumor efficacy. Almost all patients develop neutralizing anti-LMB-100 antibodies after 2 cycles of therapy. Intra-tumoral delivery of LMB-100 has been shown to induce immune cell infiltration in immune-competent mice, bearing murine malignant mesothelioma tumors. Combination with cytotoxic T-lymphocyte associated protein 4 (CTLA-4) blockage eradicates murine tumors by promoting anti-cancer immunity. Ipilimumab is a fully human anti CTLA-4 monoclonal antibody, that is approved for treatment of melanoma and in combination with nivolumab for many solid tumors. It is hypothesized that intra-tumoral delivery of anti-mesothelin immunotoxin LMB-100 in combination with ipilimumab will result in greater anti-tumor efficacy in patients with mesothelioma. Objective: To determine the safety and feasibility of intra-tumoral LMB-100 injection plus ipilimumab infusion in patients with mesothelioma To identify the recommended phase 2 dose (RP2D) of intratumorally administered LMB-100 + ipilimumab in patients with malignant mesothelioma Eligibility: Histologically confirmed pleural or peritoneal mesothelioma not amenable to potentially curative surgical resection. Have locally accessible disease suitable for intra-tumor injection of LMB-100. This includes superficial or visceral lesions. Subjects must have received prior immune checkpoint therapy with anti-Programmed cell death protein 1 (PD-1)/Programmed death-ligand 1 (PD-L1) inhibitors alone or in combination with anti-CTLA4 blocking antibodies, as well as platinum-based chemotherapy. Age >= 18 years. Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1. Adequate organ and bone marrow function Subjects with clinically significant pericardial effusion are excluded. Chemotherapy within 3 weeks or radiotherapy within 2 weeks prior to start of study therapy, is prohibited. Subjects with active central nervous system (CNS) metastasis are excluded. Subjects with active autoimmune disease for which they have received systemic immunosuppressive medications during the previous 2 years (excluding daily glucocorticoid-replacement therapy for conditions such as adrenal or pituitary insufficiency) are excluded. Subjects with active interstitial lung disease, or a history of pneumonitis or interstitial lung disease for which they had received glucocorticoids are excluded. Design: This is an open-label, single center phase I dose escalation study of intratumorally administered LMB-100 followed by ipilimumab in subjects with malignant mesothelioma. Subjects will receive intratumorally administered LMB-100, beginning at dose level 1, in 21-day cycles. LMB-100 will be given on days 1 and 4 of cycle 1, and ipilimumab is given on day 1 of cycles 2-4. Tumor biopsies will be performed prior to each administration of LMB-100, on day 1 of cycle 2 and after completion of ipilimumab therapy to evaluate changes in the tumor immune microenvironment. Up to 14 evaluable subjects will be enrolled.

A woman of childbearing potential who has a positive pregnancy test within 72 hours prior to initiation of study therapy. If the using a urine test and test positive or cannot be confirmed as negative, a serum pregnancy test will be required. Note: in the event, that 72 hours have elapsed between the screening pregnancy test and the first dose of study treatment, another pregnancy test (urine or serum) must be performed and must be negative, in order for subject to start receiving study medication. 20. Is pregnant or breastfeeding or expecting to conceive or father children within the projected duration of the study, starting with the screening visit through 4 months after the last dose of trial treatment. Pregnant women are excluded from this study because LMB-100 + ipilimumab are agents with the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with LMB-100 + ipilimumab, breastfeeding should be discontinued if the mother is treated with LMB-100 + ipilimumab. These potential risks may also apply to other agents used in this study. 21. Human immunodeficiency virus (HIV) positive patients will be excluded due to a theoretical concern that the degree of immune suppression associated with the treatment may result in progression of HIV infection. 22.
