Mesothelin-Targeted Immunotoxin LMB-100 in Combination With Tofacitinib in Persons With Previously Treated Pancreatic Adenocarcinoma, Cholangiocarcinoma and Other Mesothelin Expressing Solid Tumors

Plain-language summary
Background:
The protein mesothelin is found on many kinds of tumors. The drug LMB-100 targets cancer cells that make this protein. Researchers want to see if LMB-100 combined with another drug can help people with these tumors.
Objective:
To find a safe dose of LMB-100 plus tofacitinib in people with pancreatic cancer, bile-duct cancer, and other solid tumors that make mesothelin.
Eligibility:
People ages 18 and older with pancreatic cancer, bile-duct cancer, or any other solid tumor with mesothelin that worsened after treatment or they could not receive standard treatment
Design:
Participants will be screened with:
* Medical history
* Tumor tissue sample. If they do not have a sample, they will have a biopsy.
* Physical exam
* Blood and heart tests
* Scans and x-rays: They may have a dye injected for the scans.
Participants will take the drugs in up to three 21-day cycles. They will take tofacitinib by mouth twice a day on days 1-10 of each cycle. They will have LMB-100 injected into the blood on days 4, 6, and 8 of every cycle. Patients that do not have a medi-port may need to have a central vein access line placed.
Participants will take other drugs on the days they receive LMB-100.
Participants will repeat screening tests during the study. They may have a biopsy at the start of the first 2 cycles.
If participants must stop the study, they will have a safety visit 3-6 weeks after their last dose of the study drug. Some participants may then have visits every 6 weeks.
After treatment, participants will be contacted about once a year. They will be asked about their cancer.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
* INCLUSION CRITERIA:
* Patients must have histologically confirmed solid tumor malignancy for which no curative therapy exists.
* Pancreatic adenocarcinoma, extrahepatic cholangiocarcinoma or epithelioid subtype of mesothelioma, as determined by National Cancer Institute (NCI) Laboratory of Pathology, OR for all other tumor types, at least 20% of tumor cells must express mesothelin. Determination can be made using archival tumor tissue or fresh biopsy if archival tumor tissue is not available.
* All patients must have evaluable disease (i.e., measurable per Response Evaluation Criteria in Solid Tumors (RECIST) 1.1. or by following carbohydrate antigen 19-9 (CA19-9) tumor marker). Patients in the expansion cohort must have measurable disease, per RECIST 1.1. evaluation of measurable disease.
* Patients must have received at least one prior standard systemic treatment regimen for advanced disease OR be ineligible to receive available standards due to co-morbidities, prior toxicity, lack of standard options for tumor type, or having received all standards available for prior treatment of early-stage disease OR have refused first-line standard systemic treatment but have received prior anti-cancer treatments.
* Patients with deficient Mismatch Repair (dMMR)/high levels of MicroSatellite Instability (MSI-H) disease must have received at least one prior anti-programmed cell death 1 (PD1) therapy, be ineligible to receive this treatment due to concurrent medical conditions or have …
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
