Item 8.01 Other Events

On Thursday, May 14, 2015, Dicerna Pharmaceuticals, Inc. (the Company) announced the expansion of its ongoing Phase 1 study of DCR-MYC to include a cohort of patients with pancreatic neuroendocrine tumors (PNETs) following early signs of clinical and metabolic response and tumor shrinkage in PNET patients. DCR-MYC is an investigational Dicer substrate short-interfering RNA (DsiRNA) therapeutic targeting the MYC oncogene and the first MYC-targeting short-interfering RNA (siRNA) to enter clinical trials. The ongoing Phase 1 study, initiated in April 2014, is a multi-center, dose-escalation trial designed to assess the safety and tolerability of DCR-MYC in patients with solid tumors, multiple myeloma or lymphoma who are refractory or unresponsive to standard therapies. The study is designed to identify the maximum tolerated dose (MTD), the pharmacokinetic profile, potential pharmacodynamic effects, and antitumor activity of DCR-MYC. Once the MTD is established, an expansion cohort will be opened to enroll patients with PNET. This multi-center expansion cohort will enroll up to 20 patients with low- to intermediate-grade PNET who have demonstrated disease progression after treatment with standard therapies. Preliminary safety, tolerability, clinical, and metabolic response data from the ongoing Phase 1 trial of DCR-MYC will also be presented at the 2015 American Society of Clinical Oncology Annual Meeting in Chicago during the Tumor Biology Oral Abstract Session on Monday, June 1, 2015.
