Completed mesothelioma clinical trials have treated all study patients and finished collecting data. Once a study is completed, researchers examine the results. They will determine how and if to move forward with the treatment or technology at hand. Completed studies have improved mesothelioma survival.

Completed Mesothelioma Clinical Trials

Clinical trials may help researchers better understand mesothelioma development and treatment. Clinical studies are considered completed once all treatments and follow-ups are done. This means researchers have collected the last data point from the last patient undergoing treatment. At this point, researchers examine the study results.

In the case of a clinical trial on mesothelioma treatment, this analysis helps answer many questions, including:

  • Was the treatment effective?
  • Did the benefits of the treatment outweigh the risks?
  • Does the treatment require further study?
  • Should the treatment be approved by the U.S. Food and Drug Administration (FDA)?

Once study coordinators have finished analyzing results, they may publish them in a medical journal. They may also share the study results in the trial’s ClinicalTrials.gov record.

Mesothelioma Advances From Clinical Trials

Some completed clinical trials have tested treatments that substantially improved the prognosis for mesothelioma. Below are a few examples of noteworthy, completed mesothelioma clinical trials.

Immunotherapy for Inoperable Pleural Mesothelioma

Study Name: CheckMate-743

Study Purpose: To evaluate an immunotherapy combination treatment compared to standard chemotherapy (cisplatin and pemetrexed)

New Treatment: Opdivo® (nivolumab) and Yervoy® (ipilimumab)

Type of Mesothelioma: Inoperable pleural mesothelioma

Most Important Result: Improved survival. Patients treated with Opdivo® and Yervoy® had a median survival of 18.1 months. Those treated with standard chemotherapy had a median survival of 14.1 months.

FDA Approval Status: The FDA approved Opdivo® and Yervoy® for treatment of inoperable pleural mesothelioma in October 2020.

A New Treatment for Inoperable Pleural Mesothelioma

Study Name: STELLAR

Study Purpose: To determine the effect of a novel, electric field-based treatment for pleural mesothelioma

New Treatment: Novo-TTF-100L System

Type of Mesothelioma: Inoperable pleural mesothelioma

Most Important Result: Encouraging survival without increased systemic toxicity. Patients had standard chemotherapy treatment followed by Novo-TTF treatment. Median overall survival was 18.2 months, which compares favorably to other treatment options.

FDA Approval Status: The Novo-TTF-100L System gained FDA approval in 2019. It is approved for the treatment of inoperable pleural mesothelioma in combination with standard chemotherapy. Since the approval, the treatment has become more widely available to mesothelioma patients.

Improved Survival in Select Patients With Unresectable Pleural Mesothelioma

Study Name: MAPS (Mesothelioma Avastin® Plus Pemetrexed-cisplatin Study)

Study Purpose: To determine the effect of an immunotherapy drug on the survival of patients also undergoing standard chemotherapy treatment

New Treatment: Avastin® (bevacizumab)

Type of Mesothelioma: Inoperable pleural mesothelioma

Most Important Result: Improved survival. Patients treated with chemotherapy and Avastin® had a median survival of 18.8 months. Those treated with chemotherapy alone had a median survival of 16.1 months.

FDA Approval Status: The manufacturer did not submit an application for FDA approval. However, experts say Avastin® may be offered to patients who can tolerate it.
