The Next Frontier for Cancer Immunotherapy Trials

With its measurable impact on patient survival, there’s no denying that immunotherapy is Cancer Immunotherapy Trialsalready causing momentum in ways that cancer is treated. Drug researchers and developers are identifying new candidates in their growing pipelines and exploring combinations of immunotherapies, while regulatory agencies are providing expedited review and approval of these therapies for new indications at an unprecedented rate.

With checkpoint inhibitors from ipilimumab (Yervoy®) to nivolumab (Opdivo®) to pembrolizumab (Keytruda®) to the most recently approved atezolizumab (TecentriqTM), each breakthrough has provided new insights on how the immune system can be activated and manipulated to fight a variety of cancers.

Clinical Outcomes in NASH: Choosing the Right Endpoints

Non-alcoholic steatohepatitis (NASH) can lead to serious conditions such as cirrhosis and its complications, liver cancer and hepatic transplantation. Many patients eventually die from liver-related problems or cardiovascular disease. The challenge in developing drugs for NASH is to demonstrate an improvement in clinical outcomes. Cirrhosis takes several years to develop, and it is impractical to perform such long studies to identify treatment benefits. Therefore, to expedite the process and deliver new drugs to patients, biopharmaceutical companies have to consider surrogate endpoints that are reliable, can be obtained within a reasonable amount of time and are associated with progression of the disease.

A range of liver-related outcomes

NASH patients face many potential disorders and complications. In addition to overall death and liver-related mortality, the following endpoints should be evaluated in a clinical Clinical Outcomes in NASHoutcomes study:

  • Portal hypertension. Chronic injury to the liver results in a wounding response that leads to fibrosis, scarring and ultimately replacement of normal liver architecture with regenerative nodules. As a result of these changes, portal hypertension develops.
  • The accumulation of fluid in the abdomen results from portal hypertension. Using diuretics and reducing sodium intake often helps, but some cases are difficult to treat.

The Remarkable Rebirth of Cancer Immunotherapy

Change is in the Air
There’s reason for new hope in the ongoing battle against cancer. From standing-room-only presentations of provocative data at cancer conferences, to landmark publications and new drugs approvals, the signs are multiple and clear. Harnessing the immune system as an anti-cancer therapy–a strategy that has yet to fully deliver on its promise– is now the most exciting area of oncology drug development.

Immune Surveillance: an Invisible Malignancy Sentinel
The first chapter in the story of cancer immunotherapy is a tale that provides perspective on how evolving scientific insight serves as a backdrop to the interplay between human hopes and the sometimes capricious nature of medical advances. But that story is well beyond the scope of the next 800 or so words. However, we can take advantage of hindsight to consider some of the key lessons learned.  Continue reading

Oncology Clinical Trials: Patient Recruitment Challenges and Anatomic Pathology Services

Patient Recruitment ChallengesCancer is a disease that affects all of us; we all know someone with cancer, or have been diagnosed ourselves. Total cancer deaths worldwide in 2008 were approximately 7.6 million – approximately 13% of all deaths worldwide according to the World Health Organization. Therefore, intuitively, one would think that finding cancer patients to participate in clinical trials would not be an issue. However, that’s not the case.

Given the sheer numbers of those afflicted with cancer, we tend to lose sight of the actual prevalence of the disease at a given time in a community. When spread out over a lifetime, cancer is not as common as we assume. So, when posed with the question of where to find cancer patients for clinical trials, intuitive answers will most likely fail. However, statistics can help shed light on the patient recruitment dilemma. Continue reading
