Discussion: What is the proper role of a cardiologist in oncology clinical trials? When is cardiac expertise needed at the site? When is cardiac expertise needed in evaluation of signals?

2:30pm-3:10pm Session IV: Balancing CV risk vs benefit in Oncology Drug Development

Moderator: Jonathan Seltzer, MD, MBA, MA (ACI Clinical)

What are the patient and compound features that should be evaluated in determination of risk vs. benefit? What are the particular issues with respect to CV health/toxicity? How do we weigh these factors? Is there a common framework from which we can work to evaluate the value equation?

Panel Discussion: Regulatory, Industry, Patient, Academia, Payer

Lead Discussant: Jonathan Seltzer, MD, MBA, MA (ACI Clinical)
