简要总结

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....

详细描述

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.

结局指标

主要结局

Number of Participants Who Experienced Grades 1-5 Serious and/or Non-serious Toxicity Related (= Possibly + Probably + Definitely) to LMB-100

时间窗: Median follow-up: 3.4 months (1.9 months and 5.0 months)

Toxicity was assessed by the Common Terminology Criteria for Adverse Events (CTCAE) version 5.0. Grade 1 is mild. Grade 2 is moderate. Grade 3 is severe. Grade 4 is life-threatening. And Grade 5 is death related to adverse event.

Recommended Phase 2 Dose (RP2D) of Intratumorally Administered LMB-100 in Participants With Mesothelioma

时间窗: 21 days after first LMB-100 administration

RP2D is defined as the highest dose at which fewer than 2 of 6 participants experience a dose-limiting toxicity. A dose-limiting toxicity is defined as any Grade 4 hematological toxicity lasting greater than 5 days. Grade 3 febrile neutropenia, Grade 3 thrombocytopenia associated with bleeding episodes, any Grade 3 or greater, non-hematological toxicity with the following exceptions: tumor lysis syndrome, Grade 3 electrolyte changes associated with clinically significant consequences, Grade 3 nausea and diarrhea which has not received appropriate treatment, isolated Grade 3 fever occurring within 48 hours of LMB-100 infusion and resolving within 48 hours to ≤ Grade 2 and fully resolved within 1 week, alopecia, infusion-related reactions up to and including Grade 3, asymptomatic ≥ Grade 3 lymphopenia, leukopenia, hypoalbuminemia, electrolyte abnormalities resolving within 24 hours, and increase in alkaline phosphatase.
