Delving into the Latest Updates on LMB-100 with Synapse

Background:
Cancers that spread into the thin tissue lining your lungs (pleura) cause serious illness. They often recur when removed. These tumors include malignant pleural mesothelioma (MPM), caused by exposure to asbestos and related fibers. Malignant pleural effusions (MPEs) are caused when cancers in other parts of the body spread to the lungs and pleura. Many people diagnosed with pleural tumors survive less than a year.
Objective:
To test the safety of a study drug (LMB-100) in people. LMB-100 may help stop pleural tumors from recurring after surgery.
Eligibility:
People aged 18 years or older diagnosed with MPM or related cancer that has spread into the pleura.
Design:
Participants will undergo screening. They will have a physical exam with blood and urine tests. They will have CT scans. They will have tests that measure the how their heart and lungs function. They will provide a sample of tumor tissue to determine if their tumor expresses a protein called mesothelin.
Participants will undergo standard surgery to maximally remove the plural tumors. Then they will have LMB-100 pumped into their chest. The liquid will rinse the chest wall, diaphragm, heart sac, and surface of the lungs for 90 minutes. Then the liquid will be drained and the surgical incisions closed. The participants will be under anesthesia during this procedure.
Participants will remain in the intensive care unit for a least 48 hours. They will remain in the hospital for up to a week or more until recovered enough to be safely discharged.
Participants will return for regular follow-up visits for 2 years.

Phase I Study of Intratumor Injection of Anti-Mesothelin Immunotoxin LMB-100 With Ipilimumab in Malignant Mesothelioma

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....

A Phase II Study of LMB-100 Followed by Pembrolizumab in the Treatment of Adults With Mesothelin-Expressing Non-Squamous Non-Small Cell Lung Cancer (NSCLC)

Background:
Over 230,000 new lung cancer cases are diagnosed every year in the United States (U.S.) About 80% of lung cancers are non- small cell lung cancer (NSCLC). Most people have a more advanced stage of the disease that doesn't respond well to standard treatment. Researchers want to see if a combination of drugs may be able to help.
Objective:
To find out if LMB-100 followed by pembrolizumab can help tumors to shrink in people with NSCLC.
Eligibility:
People ages 18 and older with NSCLC that has not responded to standard therapies
Design:
Participants will be screened with:
Medical history
Physical exam
Tumor sample. If one is not available, they will have a biopsy.
Assessments of ability to perform normal activities
Lung function tests
Blood, heart, and urine tests
Computed tomography (CT) and positron emission tomography (PET). They will lie in a machine that takes pictures of the body.
Participants will take LMB-100 in 21-day cycles for up to 2 cycles. They will take the drug by injection into an arm vein on days 1, 3, and 5 of each cycle. They will stay in the hospital 7-10 days each cycle. Then they will get pembrolizumab by injection into an arm vein every 3 weeks for up to 2 years. They may be able to take pembrolizumab an additional year if their cancer gets worse.
Participants will have repeats of the screening tests throughout the study.
About 30 days and 90 days after they stop treatment, participants will have follow-up visits. Then they will have visits every 6-12 weeks. They will be followed for the rest of their life through phone calls and emails.

Systemic immune changes accompany combination treatment with immunotoxin LMB‐100 and nab‐paclitaxel

AbstractLMB‐100 is a novel immune‐conjugate (immunotoxin) that targets mesothelin. A phase 1/2 clinical trial was conducted (NCT02810418) with primary objectives assessing the safety and efficacy of LMB‐100 ± nab‐paclitaxel. Participant blood samples were analyzed for changes in serum cytokines and circulating immune cell subsets associated with response or toxicity. On Arm A, participants (n = 20) received standard 30‐minute LMB‐100 infusion with nab‐paclitaxel. Although clinical efficacy was observed, the combination caused intolerable capillary leak syndrome (CLS), a major toxicity of unclear etiology that affects many immunotoxin drugs. Participants developing CLS experienced rapid elevations in IFNγ and IL‐8 compared to those without significant CLS, along with midcycle increases in Ki‐67‐ CD4 T cells that were CD38, HLA‐DR, or TIM3 positive. Additionally, a strong increase in activated CD4 and CD8 T cells and a concurrent decrease in Tregs were seen in the single Arm A patient achieving a partial response. In Arm B, administration of single agent LMB‐100 to participants (n = 20) as a long infusion given over 24–48 h was investigated based on pre‐clinical data that this format could reduce CLS. An optimal dose and schedule of long infusion LMB‐100 were identified, but no clinical efficacy was observed even in patients receiving LMB‐100 in combination with nab‐paclitaxel. Despite this, both Arm A and B participants experienced increases in specific subsets of proliferating CD4 and CD8 T cells following Cycle 1 treatment. In summary, LMB‐100 treatment causes systemic immune activation. Inflammatory and immune changes that accompany drug associated CLS were characterized for the first time.

LMB-100 is a recombinant immunotoxin composed of a Fab linked to a toxin. It kills cells expressing human mesothelin (hMSLN), which is highly expressed on the surface of mesothelioma and many other cancer cells. Clinically, we observed some patients had delayed responses to an anti-hMSLN immunotoxin treatment, suggesting the induction of anti-tumor immunity. We aimed to develop a mouse model to investigate whether immunotoxin alone can induce anti-tumor immunity and to study the mechanism of this immunity. An immunocompetent transgenic mouse was used to grow mouse mesothelioma AB1 cells expressing hMSLN in the peritoneal cavity. Mice were treated with LMB-100, and mice with complete responses (CRs) were rechallenged with tumor cells to determine whether anti-tumor immunity developed. Changes in gene expression profiles were evaluated by Nanostring, and changes in cytokines and chemokines were checked by protein arrays. The distribution of various immune cells was assessed by immunohistochemistry. Our results show that the mice with tumor reached CRs and developed anti-tumor immunity after LMB-100 treatment alone. The primary response requires CD8 + T cells, CD4 + T cells, and B cells. Transcriptional profiling shows that LMB-100 treatment reshapes the tumor immune microenvironment by upregulating chemotaxis signals. LMB-100 treatment upregulates genes associated with tertiary lymphoid structures (TLS) development and induces TLS formation in tumors. In sum, immunotoxin-mediated cell death induces anti-tumor immunity and the development of TLS, which provides insights into how immunotoxins cause tumor regressions.
