Clinical Trial Summary

The purpose of this study is to assess the safety and tolerability of the investigational anticancer drug DCR-MYC. DCR-MYC is a novel synthetic double-stranded RNA in a stable lipid particle suspension that targets the oncogene MYC. MYC oncogene activation is important to the growth of many hematologic and solid tumor malignancies. In this study the Sponsor proposes to study DCR-MYC and its ability to inhibit MYC and thereby inhibit cancer cell growth.


Description:

In this first-in human study, DCR-MYC will be administered by 2 hour intravenous (IV) infusion, once weekly for 2 weeks followed by a rest week (3 weeks = 1 cycle), to patients with either solid tumor malignancies, multiple myeloma, or non-Hodgkins lymphoma that have not responded to previous treatment. The highest safe dose of DCR-MYC that can be administered will be identified. In addition, the pharmacokinetic (PK) profile, potential pharmacodynamic (PD) effects, as well as the antitumor activity of DCR-MYC will be evaluated.

There will be 2 expansion cohorts at the maximum tolerated dose (MTD) (or highest safe dose identified for further study which may be lower):

- Biopsy Cohort: 6 patients, tumor biopsies to be performed pre-dosing and Cycle 2/Day 11; same assessments as dose escalation cohorts

- PNET Cohort: Up to 20 patients with pancreatic neuroendocrine tumors; same assessments as dose escalation cohorts, however fewer PD (cytokine) assessments and no PK assessments

4. Patients with a malignancy that is currently not amenable to surgical intervention due to either medical contraindications or non-resectability of the tumor.

5. Dose escalation portion of study: Patients with measurable or non-measurable disease according to standard response criteria .
