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 COMPARATOR

Patients 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.

Other: Laboratory Biomarker AnalysisBiological: PembrolizumabOther: Pharmacological Study

Group II (anetumab ravtansine, pembrolizumab)

EXPERIMENTAL

Patients 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

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

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

  • 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
