How Cmed applies 20+ years’ oncology trial experience to help find new therapies
An expert view by Crista Casey, VP, Clinical and Regulatory Operations
Glioblastoma, also known as glioblastoma multiforme or GBM, can be very difficult to treat and a cure is often not possible. It is an aggressive type of cancer that can occur in the brain or spinal cord and it can develop at any age, but tends to occur more often in older adults, and has an average survival rate of 14-15 months post diagnosis1.
Hearing a diagnosis of GMB can be extremely difficult for any patient and their loved ones, as well as learning that treatments can be challenging. For GBM patients, this means a potential daily life filled with fear, depression, and anxiety, not to mention possible headaches, seizures, and vision and mobility challenges. These patients do not have much control over the hand they were dealt, so it’s important that we continue to deliver well managed trials by applying our vast knowledge and experience when helping sponsors find a treatment for this highly aggressive cancer.
Incidence Rates Are Increasing
The global incidence rate of Glioblastoma is <5 per every 100,000 with the NIH Surveillance, Epidemiology and End Results Program (SEER) estimating there will be 25,050 new cases of brain and other nervous system cancers diagnosed in 2022. In addition, recently published research suggests the incidence rate of glioblastoma is increasing2. Traditionally, survival from a GBM is less than a year and despite new developments and significant advances, recurrence is often inevitable and survival rates are low with an average life expectancy of less than 6 months after recurrence. The graphs below present survival3 and incidence4.

Treatment choices are limited with approximately five brain cancer approved therapy options available in addition to radiation, surgery, or stereotactic radiosurgery:
Unfortunately, the currently approved treatments are not without toxicity and the majority of therapies available are non-specific, delivering marginal benefit to survival. This demonstrates the need for development and advancement of new and innovative treatment options in this field.
Potential New Therapies on The Horizon
Current data shows there are 472 products in development, alone or in combination, across 252 sponsors (commercial and academic) with around 300 early phase studies in GBM planned or actively recruiting. With a poor prognosis and limited number of therapies approved specifically for glioblastoma treatment, the indication is ripe for new therapy options. Patient demand, coupled with a growing global market, (the market for GBM in 2020 was estimated at $549.1 million across United States, Canada, United Kingdom, France, Spain, Germany, Italy, and Japan) shows why novel treatment approaches are needed now.
Over the past decade, our neurologists, oncologists, and clinical teams have experienced firsthand shifts in this research space, from the use of GLIADEL® Wafers, first approved devices, recent oncolytic virotherapy advances with Teserpaturev, receiving conditional and time-limited marketing approval in Japan5, to advances in focused ultrasound translating into clinical studies for a potential GMB treatment, which navigate the challenges of drug delivery across the blood brain barrier.
When The Right Experience Matters Most
At Cmed, we understand the specific challenges in treating and researching this population and apply our medical and operational expertise when designing and implementing our glioblastoma trials. For example, we consider the following issues with a sampling of mitigations from the clinical perspective:
Operationally, there are also some administrative and support challenges such as:
Cmed is one of only 44 Clinical Research Organizations (CROs) that have supported glioblastoma studies. With the Cmed team having worked in glioblastoma research for over a decade, our experts have successfully delivered 13 commercial trials in glioblastoma, including two successful FDA product approvals.
Currently our experts are supporting two early phase studies in GBM. Both of these are ATIMP studies with the latest study, a cancer vaccine, currently in startup targeted to achieve first patient in later this year.
Key Experience in The Right Areas
Cmed is a full service, global CRO. We have been approaching trials from a point of efficiency, offering greater communication, solid partnerships, and advanced technological solutions for over twenty years. With our expert team having in-depth GBM experience across all functions, let us help you find the right treatments for these patients with limited time by building success into your product or project planning.
