Trial Summary

What is the purpose of this trial?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.

Eligibility Criteria

This trial is for patients with mesothelin-positive pleural mesothelioma who've had platinum-based chemotherapy. They must have measurable disease, normal organ function, and agree to contraception. Exclusions include HIV, hepatitis B/C, recent monoclonal antibody therapy or transfusions, active secondary cancers, certain drug interactions, and history of severe lung conditions.

Inclusion Criteria

My tumor shows high levels of mesothelin in more than 30% of its cells.

You have a low white blood cell count.

Your total bilirubin levels are within the normal range for the hospital where you are being treated.

Participant Groups

The study tests pembrolizumab (an immunotherapy) alone or combined with anetumab ravtansine (a targeted therapy that delivers chemo directly to cancer cells). It aims to see if this combination is more effective in treating pleural mesothelioma than pembrolizumab alone.

Experimental Treatment

Active Control

Group I: Group II (anetumab ravtansine, pembrolizumab)Experimental Treatment4 Interventions

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.

Group II: Group I (pembrolizumab)Active Control3 Interventions

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.
