Intra-tumoral Mitazalimab (CD40 Antibody) With Irreversible Electroporation (IRE) in Locally Advanced Pancreas Cancer
Recruiting
This is a phase I study of an agonistic CD40 antibody (mitazalimab) injected intratumorally at the time of surgical IRE in patients with locally advanced pancreatic cancer. Intratumoral delivery has potential to be more effective than systemic (intravenous) delivery while decreasing the systemic side effects of immunotherapy. We hypothesize that local delivery of mitazalimab at the time of IRE in patients with locally advanced pancreatic cancer will be safe, augment the immune effects of IRE, an... Read More

Lung Transplant READY CF 2: A Multi-site RCT
Recruiting
Lung transplant is an option for treating end-stage lung disease in cystic fibrosis (CF). In the United States, more people with CF and low lung function die each year than undergo lung transplant. More than half of people with CF who die without a lung transplant were never referred for consideration. Patient preference not to undergo lung transplant may account for 25-40% of decisions to defer referral. Rates of death without transplant are higher for people with CF who are members of marginal...
