Immunotherapy + Chemotherapy for Sarcoma
Trial Summary
What is the purpose of this trial?
This phase II trial compares the effect of immunotherapy (pembrolizumab) plus chemotherapy (doxorubicin) to chemotherapy (doxorubicin) alone in treating patients with undifferentiated pleomorphic sarcoma (UPS) or a related poorly differentiated sarcoma that has spread from where it first started (primary site) to other places in the body (metastatic) or that cannot be removed by surgery (unresectable). Doxorubicin is in a class of medications called anthracyclines. Doxorubicin damages the cell's DNA and may kill tumor cells. It also blocks a certain enzyme needed for cell division and DNA repair. A monoclonal antibody is a type of protein that can bind to certain targets in the body, such as molecules that cause the body to make an immune response (antigens). 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. Adding immunotherapy (pembrolizumab) to the standard chemotherapy (doxorubicin) may help patients with metastatic or unresectable UPS or a related poorly differentiated sarcoma live longer without having disease progression.
Will I have to stop taking my current medications?
The trial protocol does not specify if you need to stop taking your current medications. However, if you are on daily corticosteroids, you must finish tapering off before starting the study treatment.
What data supports the effectiveness of the drug doxorubicin in treating sarcoma?
Research shows that doxorubicin is one of the most active drugs for treating sarcomas, often used in combination with other agents like ifosfamide. However, its effectiveness can be limited by resistance mechanisms, such as the activation of the insulin-like growth factor-I receptor, which can reduce the drug's ability to kill cancer cells.12345
What safety data exists for the combination of immunotherapy and chemotherapy, specifically involving doxorubicin, for sarcoma treatment?
Doxorubicin, a chemotherapy drug, is known to cause side effects like heart damage (cardiotoxicity), low white blood cell counts (myelosuppression), hair loss (alopecia), nausea, and vomiting. Liposomal formulations of doxorubicin, which are designed to reduce these side effects, have shown lower risks of heart damage and myelosuppression compared to conventional doxorubicin. However, they may increase the risk of a skin condition called palmar-plantar erythrodysesthesia (PPE).678910

Eligibility Criteria
This trial is for adults over 18 with specific aggressive sarcomas, like undifferentiated pleomorphic sarcoma or malignant fibrous histiocytoma, that have spread and can't be surgically removed. Women must have started menstruating to participate.Inclusion Criteria
Trial Timeline
Screening
Participants are screened for eligibility to participate in the trial
Treatment
Participants receive doxorubicin and pembrolizumab or doxorubicin alone. Treatment repeats every 21 days for 6 cycles, with pembrolizumab continuing for up to 2 years in the absence of disease progression or unacceptable toxicity.
Follow-up
Participants are monitored for safety and effectiveness after treatment completion. Follow-up occurs every 3 months for 2 years, then every 6 months for up to 10 years.
