Expanded Access

Sometimes called “compassionate use”, Expanded Access involves the use of an investigational drug when a patient with a serious disease or life-threatening condition is unable to participate in a clinical trial. Calico does not currently offer an Expanded Access program; participation in our clinical trials is the only way for patients to gain access to any of Calico’s investigational drugs. As more data on the safety and efficacy of our investigational drugs become available, we will continuously review and may update our policy on Expanded Access.
