What is the purpose of this trial?

This trial tests a new treatment called sacituzumab govitecan (an antibody-drug conjugate) for people with mesothelioma, a type of cancer affecting the lung lining. The goal is to determine if this treatment can slow the disease or improve symptoms. Participants will receive the treatment until their disease worsens or they experience severe side effects. This trial may suit those with confirmed mesothelioma who have tried another treatment and are willing to undergo biopsies as part of the study. As a Phase 2 trial, the research focuses on measuring the treatment's effectiveness in an initial, smaller group, offering participants a chance to contribute to important findings.

Do I have to stop taking my current medications to join the trial?

The trial protocol does not specify if you need to stop taking your current medications. However, you must not have received any cytotoxic or immunologic systemic therapy within 3 weeks before starting the trial treatment.

Is there any evidence suggesting that sacituzumab govitecan is likely to be safe for humans?

Research shows that sacituzumab govitecan is usually well-tolerated by patients. In earlier studies, patients who received this treatment experienced fewer side effects than those on some standard cancer drugs. However, like many cancer treatments, it can still cause unwanted effects, such as tiredness, nausea, and diarrhea. Serious side effects occur less frequently. This trial is ongoing, so researchers continue to gather information about its safety. Sacituzumab govitecan is also approved for treating other types of cancer, suggesting it is generally safe for people. Always consult a doctor to understand the potential risks. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising for mesothelioma?

Sacituzumab Govitecan is unique because it combines an antibody that targets a protein commonly found on cancer cells with a potent chemotherapy drug. This dual-action approach helps deliver the chemotherapy directly to the cancer cells, potentially sparing more healthy cells than traditional chemotherapy methods. Researchers are excited about this treatment for mesothelioma because it introduces a targeted mechanism that may improve effectiveness and reduce side effects compared to current standard treatments like chemotherapy alone.

What evidence suggests that sacituzumab govitecan might be an effective treatment for mesothelioma?

Research shows that sacituzumab govitecan may help treat certain cancers by targeting TROP-2, a protein often found on cancer cells. Studies have shown it slows tumor growth in various cancers and proves more effective at stopping tumor growth than gemcitabine, a common chemotherapy drug. Although specific data for mesothelioma is still being gathered, these findings suggest potential benefits for patients with this condition. Participants in this trial will receive sacituzumab govitecan, and its ability to disrupt cancer cell survival is a key reason for its potential success. ^{1 2 3 4 5}

What Are the Treatments Tested in This Trial?

Interventions

• Sacituzumab Govitecan

Trial Overview The study tests Sacituzumab Govitecan in patients with mesothelioma until they experience disease progression, intolerable side effects, or decide with their doctor that it's best to stop. The drug is given repeatedly over time as long as it's safe and potentially beneficial.

How Is the Trial Designed?

Group I: Participants with Mesothelioma Experimental Treatment 1 Intervention

Participants will have pathologically confirmed diffuse pleural mesothelioma. Patients will undergo cross-sectional imaging after the first 2 cycles and subsequently after every 3 cycles until disease progression. Biopsies will take place at screening, prior to cycle 3, and an optional biopsy at the end of treatment if consent was obtained and deemed to be safe and feasible. Patients treated on study who are removed prior to the Cycle 3 tumor assessment will be evaluated for toxicity only and replaced. All patients treated past the Cycle 3 tumor assessment will be include in the toxicity and efficacy assessments.

Published Research Related to This Trial

Sacituzumab govitecan, an antibody-drug conjugate targeting Trop-2, showed promising therapeutic activity in a phase I trial with 25 patients suffering from various metastatic solid cancers, achieving partial responses in two patients and stable disease in 16 others.

The maximum tolerated dose was determined to be 12 mg/kg for the first cycle, with lower doses (8 and 10 mg/kg) being safer for extended treatment, leading to acceptable toxicity levels and disease control for up to 36 weeks.

Sacituzumab govitecan (IMMU-132) is an antibody-drug conjugate that effectively targets Trop-2, showing significant antitumor effects in various solid tumors, including gastric and pancreatic cancers, in mouse models.

The drug demonstrated a favorable pharmacokinetic profile with a mean residence time of 15.4 hours, and ongoing clinical trials are confirming its anticancer activity in patients with Trop-2 expressing tumors.

Sacituzumab govitecan (IMMU-132) demonstrated a predictable pharmacokinetic profile and manageable toxicity in patients with advanced epithelial cancers, with doses of 8 mg/kg (n=81) and 10 mg/kg (n=97) showing safety and efficacy.

The treatment resulted in objective responses in various cancer types, particularly metastatic triple-negative breast cancer, supporting the use of the 10 mg/kg dose for future clinical development.

Sacituzumab govitecan, an antibody-drug conjugate targeting TROP-2, shows promise in treating malignant pleural mesothelioma (MPM), particularly in TROP-2-positive cell lines, as it effectively induces cell cycle arrest and cell death.

TROP-2 was expressed in 6 out of 17 MPM cell lines, and sensitivity to the drug SN38 was observed in 10 of these lines, suggesting that TROP-2 expression could serve as a biomarker for selecting patients who may benefit from sacituzumab govitecan therapy.

Sacituzumab govitecan is an antibody-drug conjugate that targets Trop-2 and delivers a topoisomerase I inhibitor, showing promise in treating metastatic triple-negative breast cancer (mTNBC) after at least two prior therapies.

In April 2020, it received accelerated approval in the USA for mTNBC, and it is currently undergoing further clinical trials for various cancers, indicating its potential as a versatile treatment option.

Sacituzumab Govitecan: First Approval. Syed, YY.[2021]

In a study of 50 patients with metastatic small cell lung cancer (mSCLC) who had been heavily pretreated, sacituzumab govitecan demonstrated a 14% objective response rate, with 60% of patients showing tumor shrinkage, indicating its potential efficacy as a treatment option.

The treatment was found to be generally safe, with manageable side effects; however, significant adverse events included neutropenia (34%) and fatigue (13%). This suggests that while effective, careful monitoring for side effects is necessary.

Sacituzumab govitecan is an antibody-drug conjugate that targets Trop-2 and has shown a 33.3% overall response rate in patients with metastatic triple-negative breast cancer (mTNBC) who have received at least two prior therapies, based on a phase I/II study with 108 participants.

The treatment has a median duration of response of 7.7 months, and while it is generally well-tolerated, common side effects include nausea, neutropenia, and fatigue, indicating a need for monitoring during treatment.
