Summary

Background:

Treatment outcomes for people with pleural or peritoneal mesothelioma are often poor. The drug LMB-100 can attack and kill cancer cells. The drug pembrolizumab helps the immune system fight cancer. Together, these drugs might help people with these cancers.

Objective:

To test if pembrolizumab given after LMB-100 shrinks tumors in people with pleural or peritoneal mesothelioma.

Eligibility:

People ages 18 and older with pleural or peritoneal mesothelioma that has not responded to platinum-based therapy

Design:

Participants will be screened with:

Tumor sample. Participants will have a biopsy if one is needed.

Medical history

Physical exam

Blood, heart, and urine tests

X-rays and scans: Participants will lie on a table. A machine will take pictures of the body.

Participants will receive LMB-100 by intravenous (IV) on days 1, 3, and 5 of two 21-day cycles. They will be observed for up to 2 hours after each infusion. They will receive drugs like Benadryl, Tylenol, and Zantac to help with side effects.

Starting with the 3rd cycle, participants will receive pembrolizumab by IV on day 1 of each 21-day cycle for up to 2 years.

Participants will have blood and urine tests, heart tests, and chest x-rays at least once per cycle. They will have scans every 6 weeks.

Participants may opt to provide tumor biopsies before starting the first cycle, after 2 cycles of LMB-100, and after 2 cycles of pembrolizumab.

Participants will a follow-up visit 4-6 weeks after their last drug dose of the study drug. This includes blood and heart tests and scans. They may then have scans every 6 weeks.

Participants will be contacted once a year for follow-up.
