Brief Summary
This phase I/II trial studies the side effects and how well pembrolizumab with or without anetumab ravtansine works in treating patients with mesothelin-positive pleural mesothelioma. Anetumab ravtansine is a monoclonal antibody, called anetumab, linked to a chemotherapy drug, called ravtansine. Anetumab is a form of targeted therapy because it attaches to specific molecules (receptors) on the surface of cancer cells, known as mesothelin receptors, and delivers ravtansine to kill them. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving pembrolizumab and anetumab ravtansine may work better in treating patients with mesothelin-positive pleural mesothelioma.

Outcome Measures
Primary Outcomes (2)
Phase 2 Confirmed Tumor Response Rate (Phase II)
Will be assessed using Response Evaluation Criteria in Solid Tumors version 1.1 criteria. The proportion of successes will be estimated in each group by the number of successes divided by the total number of evaluable patients. Confidence intervals for the true success proportion will be calculated in each arm. Comparison of confirmed response rates between the two treatment groups will be performed using a one-sided z-test with pooled variance at significance level 0.10. Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0) for target lesions and assessed by MRI: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), \>=30% decrease in the sum of the longest diameter of target lesions; Overall Response (OR) = CR + PR.
Up to 2 years
Phase I - Recommended Phase 2 Dose of Ametumab Ravtansine With Combination of Pembrolizumab
All patients that have received any amount of the combination anetumab ravtansine and pembrolizumab will be evaluable for toxicity. Please note this is different from the definition of evaluable for dose-limiting toxicity (DLT) where patients who cannot complete the planned dose due to reasons other than toxicity will be replaced.
Up to 2 years
Secondary Outcomes (7)
Phase 2 Duration of Response
Up to 2 years
Phase 2 Overall Survival
From the start of treatment to death due to any cause, assessed up to 2 years
Phase 2 Progression Free Survival
From the start of treatment to the earliest date of documentation of disease progression or death due to any cause, assessed up to 2 years
Pharmacokinetics of Anetumab Ravtansine
Days 1 and 3 of courses 1 and 8
Change in Megakaryocyte Potentiating Factor Levels Assessed in Tumor
Baseline up to 2 years
- +2 more secondary outcomes
Study Arms (2)
Group I (pembrolizumab)
ACTIVE COMPARATORPatients receive pembrolizumab IV over 30 minutes on day 1. Cycles repeat every 21 days for up to 24 months in the absence of disease progression or unacceptable toxicity. Upon radiologic documentation of disease progression, patients may cross over to Group II.
Group II (anetumab ravtansine, pembrolizumab)
EXPERIMENTALPatients receive anetumab ravtansine IV over 1 hour and pembrolizumab IV over 30 minutes on day 1. Cycles repeat every 21 days for up to 12 months for anetumab ravtansine and up to 24 months for pembrolizumab in the absence of disease progression or unacceptable toxicity.

Eligibility Criteria
You may qualify if:
- PRE-REGISTRATION
- Patients must have histologically or cytologically confirmed malignant pleural mesothelioma
- Patient is willing to submit a tissue sample to test for expression of mesothelin
- Note: Tissue sample for mesothelin assay may have been collected prior to, during or after receipt of the frontline chemotherapy; patients will not be required to submit another tissue sample after receipt of the chemotherapy
- Patients must have received platinum based chemotherapy
- REGISTRATION
- For phase 2 only:
- Patient has measurable disease per Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 for non-pleural disease or modified RECIST 1.1 (mRECIST) for pleural disease
- Note: For pleural disease, this is defined as at least one lesion that can be accurately measured perpendicular to the chest wall or mediastinum that is \>= 10 mm (\>= 1 cm); for extra pleural disease, measurable disease is defined as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded for non-nodal lesions and short axis for nodal lesions) as \>= 10 mm (\>= 1 cm) for non-nodal lesions and \>= 15 mm (\>= 1.5 cm) for nodal lesions with spiral computed tomography (CT) scan, magnetic resonance imaging (MRI), or calipers by clinical exam as per RECIST 1.1
- Tissue submitted for testing at pre-registration shows moderate or stronger mesothelin expression in \>= 30% of the tumor cells
- For phase 1 and 2:
- Patients must have received platinum-based therapy with or without bevacizumab
- Eastern Cooperative Oncology Group (ECOG) performance status \< 2 (Karnofsky \>= 70%)
- Leukocytes \>= 3,000/mcL
- Absolute neutrophil count \>= 1,500/mcL
- +24 more criteria
You may not qualify if:
- Patients who have received any monoclonal antibody therapy within 4 weeks prior to entering the study
- Patients who have not recovered from adverse events due to prior anti-cancer therapy (i.e., have residual toxicities \> grade 1)
- Note: Patients with =\< grade 2 neuropathy or =\< grade 2 alopecia are an exception to this criterion and may qualify for the study
- Note: If patients received major surgery, they must have recovered adequately from the toxicity and/or complications from the intervention prior to starting therapy
- Patients who are receiving any other investigational agents
- Patients with known brain metastases with progressive neurologic dysfunction, requirement of steroids and lack of improvement on head imaging obtained prior to consent to this clinical trial should be excluded because of their poor prognosis and because they would confound the evaluation of neurologic and other adverse events
- Note: Patients with previously treated brain metastases may participate provided they are stable (without evidence of progression by imaging using the identical imaging modality for each assessment, either magnetic resonance imaging \[MRI\] or computed tomography \[CT\] scan, for at least 4 weeks prior to the first dose of trial treatment and any neurologic symptoms have returned to baseline), have no evidence of new or enlarging brain metastases, and are not using steroids for at least 7 days prior to trial treatment
- Note: Patients with carcinomatosis meningitis should also be excluded
- History of allergic reactions attributed to compounds of similar chemical or biologic composition to anetumab ravtansine or pembrolizumab
- Patients receiving any medications or substances that are strong inhibitors or inducers of CYP3A4, including herbal preparation containing CYP3A4 inducers (e.g., St. John's Wort), grapefruit and grapefruit juice (CYP3A4 inhibitor), within 2 weeks before the start of study treatment
- Patients are prohibited from receiving the following therapies during the screening and treatment phases (including retreatment for post-complete response relapse) of this trial:
- Antineoplastic systemic chemotherapy or biological therapy
- Immunotherapy not specified in this protocol
- Chemotherapy not specified in this protocol
- Investigational agents other than anetumab ravtansine and pembrolizumab
- +18 more criteria
