Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
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.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Background:
* Mesothelin is expressed in approximately half of all lung adenocarcinomas.
* LMB-100 has demonstrated anti-tumor efficacy against several mesothelin expressing tumor models including non-small cell lung cancer (NSCLC). Programmed death ligand 1 (PD-1) is an Ig superfamily member related to cluster of differentiation (CD28) and cluster of differentiation 152 (CTLA-4) that has been shown to negatively regulate antigen receptor signaling upon engagement of its ligands.
* Pembrolizumab, an immunoglobulin G4 (IgG4) monoclonal antagonist antibody to PD-1, is Food and Drug Administration (FDA) approved in the frontline for advanced non-squamous NSCLC as a single agent with high programmed death-ligand 1 (PD-L1) expression \[tumor proportion score (TPS) \>=50%\] or in combination with platinum-based doublet chemotherapy (PD-L1 unselected). It also approved in the second-line for high PDL1 expressing tumors (TPS \>=1%).
* Combination treatment with LMB-100 plus pembrolizumab results in greater anti-tumor efficacy in murine lung cancer model.
Objectives:
-To determine the objective response rate of LMB-100 followed by pembrolizumab in the treatment of subjects with mesothelin-expressing non-squamous non-small cell lung cancer (NSCLC) previously treated with immune checkpoint inhibitors.
Eligibility:
* Histologically confirmed locally advanced or metastatic non-squamous, non-small cell lung cancer lacking an EGFR sensitizing mutation, anaplastic lymphoma kinase (ALK) or ROS oncogene 1 (ROS1) gene rearrangement and not amenable to potentially curative surgical resection or chemoradiation.
* Tumor mesothelin expression of at least 25% of tumor cells as determined by the Laboratory of Pathology at the NCI.
* Subjects must have at least progressed after one prior platinum-based doublet chemotherapy AND standard immune checkpoint inhibitor (ICI) with either frontline single-agent pembrolizumab, or in combination with platinum-based doublet chemotherapy, or second-line single-agent nivolumab, pembrolizumab, or atezolizumab.
* Age \>= 18 years.
Design:
* This is an open-label, single center phase II study of LMB-100 followed by pembrolizumab in subjects with mesothelin expressing NSCLC who have progressed on standard therapies
* Subjects will receive LMB-100 at the single agent maximum tolerated dose (MTD) (140mg/kg) on days 1, 3 and 5 of a 21-day cycle for up to 2 cycles and pembrolizumab 200 mg on day 1 of cycle 3 of a 21- day cycle (or cycle 2 if disease progression is observed after 1 cycle) onwards until disease progression (on or after pembrolizumab) or intolerable toxicity for a maximum of 2 years (unless second course initiated).
* The total accrual ceiling for the screening will be set at 100 total patients in order to treat 23 subjects.
* Mesothelin is expressed in approximately half of all lung adenocarcinomas.

* Must have left ventricular ejection fraction \>50%.
* The effects of LMB-100 on the developing human fetus are unknown. For this reason and because anti-PD-1 antibodies such as pembrolizumab are assumed to be teratogenic:
* A male participant must agree to use contraception during the treatment period and for at least 180 days after the last dose of study treatment and refrain from donating sperm
* A female participant is eligible to participate if she is not pregnant, not breastfeeding, and at least one of the following conditions applies:

* Ability of subject to understand and the willingness to sign a written informed consent document.
* Subjects with non-life-threatening immune-related endocrinopathies or adverse events (AEs) reduced to Grade 1 or 0 after withholding immune checkpoint inhibitors (ICI) or medical intervention are eligible as long as the AE resolved within 12 weeks of last dose and not requiring corticosteroids.
EXCULSION CRITERIA:
* Is currently participating in or has participated in a study of an investigational agent or has used an investigational device within 4 weeks prior to the first dose of study treatment. Note: Participants who have entered the follow-up phase of an investigational study may participate as long as it has been 4 weeks after the last dose of the previous investigational agent.
* Has known active central nervous system (CNS) metastases and/or carcinomatous meningitis. Participants with previously treated brain metastases may participate provided they are radiologically stable, i.e., without evidence of progression for at least 4 weeks by repeat imaging (note that the repeat imaging should be performed during study screening), clinically stable and without requirement of steroid treatment for at least 14 days prior to first dose of study treatment.
* Subjects who have received prior therapy with LMB-100.
Has received prior systemic anti-cancer therapy including investigational agents within 4 weeks prior to start of study therapy.
* Note: Participants must have recovered from all AEs due to previous therapies to \<=Grade 1 or baseline. Participants with \<=Grade 2 neuropathy may be eligible.
* Note: If participant received major surgery, they must have recovered adequately from the toxicity and/or complications from the intervention prior to starting study treatment.
* Has received prior radiotherapy within 2 weeks of start of study treatment. Participants must have recovered from all radiation-related toxicities, not require corticosteroids, and not have had radiation pneumonitis. A 2-week washout is permitted for palliative radiation (\<=2 weeks of radiotherapy) to non-CNS disease.
* Has received a live vaccine within 30 days prior to the first dose of study drug. Examples of live vaccines include, but are not limited to, the following: measles, mumps, rubella, varicella/zoster (chicken pox), yellow fever, rabies, Bacillus Calmette (BCG), and typhoid vaccine. Seasonal influenza vaccines for injection are generally killed virus vaccines and are allowed; however, intranasal influenza vaccines (e.g., FluMist(R)) are live attenuated vaccines and are not allowed.
* Has a diagnosis of immunodeficiency or is receiving chronic systemic steroid therapy (in dosing exceeding 10 mg daily of prednisone equivalent) or any other form of immunosuppressive therapy within 7 days prior to start of study therapy.
* Has active autoimmune disease that has required systemic treatment in the past 2 years (i.e., with use of disease modifying agents, corticosteroids or immunosuppressive drugs). Replacement therapy (e.g.., thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment.
* Has a history of (non-infectious) pneumonitis/interstitial lung disease (ILD) that required steroids or has current pneumonitis/ILD
* Has a history or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the study, interfere with the subject's participation for the full duration of the study, or is not in the best interest of the subject to participate, in the opinion of the treating investigator.
* Has known psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial.
* A WOCBP who has a positive urine pregnancy test within 72 hours prior to start of study therapy. If the urine test is 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.
* Is pregnant or breastfeeding or expecting to conceive or father children within the projected duration of the study, starting with the screening visit through 180 days after the last dose of trial treatment. Pregnant women are excluded from this study because LMB-100 + pembrolizumab 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 + pembrolizumab, breastfeeding should be discontinued if the mother is treated with LMB-100 + pembrolizumab. These potential risks may also apply to other agents used in this study.
* Has a known history of Human Immunodeficiency Virus (HIV). 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. (Note: No HIV testing is required)
* Has a known history of Hepatitis B (defined as Hepatitis B surface antigen \[HBsAg\] reactive) or known active Hepatitis C virus (defined as HCV ribonucleic acid (RNA \[qualitative\] is detected) infection. or active hepatitis B virus (HBV) or HCV infection. (Note: No testing for Hepatitis B and Hepatitis C is required.)
* Has a known additional malignancy that is progressing or has required active treatment within the past 2 years. Note: Participants with basal cell carcinoma of the skin, squamous cell carcinoma of the skin, or carcinoma in situ (e.g., breast carcinoma, cervical cancer in situ) that have undergone potentially curative therapy are not excluded.
* Has an active infection requiring systemic therapy.
* Participants with contra-indication and/or history of severe hypersensitivity reactions to any components related to LMB-100 or pembrolizumab (or any other immune checkpoint inhibitor such as Programmed death ligand 1 (PD-1), programmed death-ligand 1 (PD-L1) and cluster of differentiation 152 (CTLA-4).
* Active or uncontrolled infections.
* Subjects who experienced severe or life-threatening immune-related AEs with prior immune checkpoint therapy requiring medical intervention (steroid or immunosuppressant drugs) and permanent discontinuation of therapy, will be excluded. These include, but not limited to colitis, autoimmune hepatitis, hypophysitis, hyperthyroidism, nephritis, myocarditis, Guillain-Barré syndrome (GBS), encephalitis.
* Subjects with a history of pneumonitis that required steroids will be excluded.
* Recruitment Strategies
Information about the study will be posted on sites such as clinicaltrials.gov and the Center for Cancer Research (CCR) recruitment website. Subjects will also be drawn from patients seen at the thoracic clinic at the National Institutes of Health (NIH) Clinical Center as well as from referrals from outside providers. Social media platforms managed by NIH/National Cancer Institute (NCI) may also be used to publicize the study. There is no plan to advertise this study at this time.
