Examining Current Clinical Trials and Mesothelioma Treatment Trends

Watch Mary Hesdorffer, the Meso Foundation’s executive director and mesothelioma expert, in this opening presentation at the 2015 International Symposium on Malignant Mesothelioma. In this video, she discusses the state of mesothelioma research and treatment options. Her discussion begins with a focus on clinical trials. With 92 open clinical trials for mesothelioma, of which 55 include some form of pharmacologic or radiotherapy intervention, mesothelioma research has never looked more hopeful.

Currently, research is focusing beyond chemotherapy, taking a look at how manipulation of the immune system can advance treatment options. SS1P, an immunotoxin, illustrates this new area of research. Other trials are looking at modulating the immune system with t-cells in hopes of starting immune system surveillance that will destroy the bad cells.

Available clinical trials now include vaccine treatments, chemotherapy, and, sometimes, a combination of both. For example, the CRS-207 trial combines a mesothelin-targeting vaccine with traditional chemotherapy.

Various new trials are also in the works. Verastem, a pharmaceutical company, is beginning a trial that uses an agent to target cancer stem cells to delay the time to progression after having a response or stabilization with first-line therapy.

Another focus in mesothelioma research is targeting angiogenesis. Angiogenesis is the ability for cancer cells to find new blood supplies so they can continue growing. This type of research is working on ways to cut off this blood supply.

Mary notes that the face of cancer treatment is changing, and it is important that patients are healthy enough to receive new treatments. When considering a new clinical trial or treatment, a patient must consider the impact it can have on their health, how it will impact their cancer, and whether or not the new drugs will prevent them from being able to try other treatments in the future.

Message to Pharma: Large Trials in Mesothelioma are Possible

Dr. Lee Krugby Lee Krug, MD, Memorial Sloan Kettering Cancer Center

This month, a notification was sent to investigators on the DETERMINE Trial that accrual will be completed by the end of October. DETERMINE is an international, randomized trial comparing treatment with an immunotherapy drug called tremelimumab to treatment with placebo as second or third line therapy in patients with malignant mesothelioma. The trial opened in May, 2013, and in just 17 months will have enrolled 564 patients! This is a notable achievement. To put this in perspective, the last phase III of this magnitude testing vorinostat in a comparable group of patients (VANTAGE Trial) took 5 1/2 years to enroll 660 patients. There are differences between these two trials that could have accounted, in part, to the more rapid accrual. In DETERMINE, 2/3 of the patients receive the study drug, 1/3 get placebo, while in VANTAGE it was half and half. Also, immunotherapy drugs such as tremelimumab have garnered tremendous excitement in the oncology field due to their promising results in numerous cancers such as melanoma skin cancer and lung cancer. Yet, despite these differences, this accomplishment of completing a trial of this size in such a short period of time should be a wake-up call to the pharmaceutical industry. Historically, drug companies have been reluctant to undertake large trials in mesothelioma due to concerns about feasibility and slow accrual. But this trial demonstrates the potential. Patients with mesothelioma urgently need better treatments, and with only one chemotherapy regimen approved, there is a tremendous opportunity to impact the outcomes for these patients. So here is the message to pharma: Large trials in mesothelioma are possible, and the community of patients with mesothelioma is eager to participate.

Lee M. Krug, MD, is an Associate Attending Physician in the Division of Thoracic Oncology, Department of Medicine at Memorial Sloan-Kettering Cancer Center in New York, New York where he completed a fellowship and chief fellowship in medical oncology.

Meet the Mesothelioma Experts: Stephen Isaacs Discusses New Clinical Trial Using Listeria Bacteria

Stephen IsaacsOn September 10, the Meso Foundation will interview Stephen Isaacs, the chairperson, president, and CEO of Adura BioTech, during a new installment of the Foundation’s Meet the Mesothelioma Experts live broadcast. The interview will be led by the Meso Foundation’s executive director and mesothelioma expert nurse practitioner, Mary Hesdorffer, APRN.

The focus of the interview will be Audo BioTech’s experimental therapy for malignant pleural mesothelioma, known as CRS-207. CRS-207 is a weakened form of Listeria bacteria modified to reduce its ability to cause infections, but still able to stimulate the immune system.

The interview will be available live on September 10, at 1PM EST, by calling into a conference-call number. The interview is free of charge, but listeners must RSVP ahead of time by visiting curemeso.org/experts in order to receive a call-in number.

In his position at Aduro BioTech, Mr. Isaacs initiated the company’s current immunotherapy program based on attenuated strains of Listeria monocytogenes. He was responsible for recruiting key members of the current vaccine team with deep expertise in the biology of Listeria. Mr. Isaacs has published over 20 peer-reviewed scientific articles and is an inventor on over 40 issued patents.

More Promising Mesothelioma Clinical Trials than Ever Before

Research continues to search for a cure as more mesothelioma clinical trials than ever before are underway.During the July 2014 board meeting of the Mesothelioma Applied Research Foundation, mesothelioma expert and executive director of the Meso Foundation, Mary Hesdorffer, APRN, stated that mesothelioma patients today have more promising clinical trials to choose from than ever before.

In her talk, she mentioned several trials that have been reporting increased survival and response rates. Some include novel radiation treatments, while the focus of others is within the field of immunotherapy. One trial, in particular, is looking very promising with a 69% durable response in a small group of patients. Ms. Hesdorffer stated that a new, larger trial currently underway is looking to confirm these results.

“A clinical trial is a unique opportunity for a patient to try something new and innovative that could have a very positive impact on the patient’s disease,” said Ms. Hesdorffer. “Having options is an important step forward in a disease that merely a decade ago was seen as hopeless,” she added.

Ms. Hesdorffer provides free consultations about clinical trials, as well as other issues pertaining to mesothelioma, as part of the Mesothelioma Applied Research Foundation’s patient services.

“While healthcare providers aren’t able to review all clinical trial options with their patients due to time constrains, at the Meso Foundation it is our job to spend the necessary time to go through all viable options while taking into consideration insurance coverage, stage of disease, histology and readiness to participate in a clinical trial,” added Ms. Hesdorffer.

Mary Hesdorffer, MS, APRN-BC, is a nurse practitioner with over 16 years of experience in mesothelioma treatment. She is an expert in mesothelioma clinical trials and her work has been published in a variety of scientific journals.

The Mesothelioma Applied Research Foundation has recently released a downloadable brochure about mesothelioma clinical trials, which can also be requested by mail, and lists all mesothelioma clinical trials on its website.
