Phase Ib/2, Multicenter, Dose Escalation Study of DCR-MYC in Patients With Hepatocellular Carcinoma

Phase 1b/2, Multicenter, Dose Escalation Trial to Determine the Safety, Tolerance, Maximum Tolerated Dose and Recommended Phase 2 Dose of DCR-MYC, a Lipid Nanoparticle (LNP)-Formulated Small Inhibitory RNA (siRNA) Oligonucleotide Targeting MYC, in Patients With Hepatocellular Carcinoma (HCC)

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.

Detailed description

In this second study in humans, 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 hepatocellular carcinoma who are either sorafenib-refractory, sorafenib-intolerant despite dose reduction and best supportive care, or for whom neither sorafenib nor other suitable therapy is available. During the Phase 1b portion of the study, 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 preliminary antitumor activity of DCR-MYC will be evaluated. During the Phase 2 portion of the study, up to 30 patients will be treated at the MTD identified in Phase 1b in order to further evaluate safety and tolerability, as well as assess the antitumor activity, of DCR-MYC.

Conditions

• Hepatocellular Carcinoma

Interventions

Type	Name	Description
DRUG	DCR-MYC	Dosing: 2 hour IV infusion on Day 1 and 8 of each 21 day cycle. Starting dose: 0.125mg/kg/dose Number of cycles: until progression or unacceptable toxicity develops. PHASE 1b Dose escalation: 50% or 25% increase in subsequent cohorts depending upon toxicity until maximum tolerated dose (MTD) is identified. PHASE 2 Cohort expansion at the MTD: Additional patients to be treated at the highest dose tolerated to assess efficacy and further assess safety
