Brief 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.

Condition or disease Intervention/treatment Phase
Solid Tumors Multiple Myeloma Non-Hodgkins Lymphoma Pancreatic Neuroendocrine Tumors PNET NHL Drug: DCR-MYC Phase 1

Detailed 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

Arm Intervention/treatment
Experimental: DCR-MYC
Patient groups (cohorts) will receive a single dose level of DCR-MYC; the dose level of DCR-MYC will be increased in subsequent cohorts

Dosing: 2 hour IV infusion on Day 1 and 8 of each 21 day cycle.

Starting dose: 0.1mg/kg/dose

Dose escalation: 100%, 50%, or 25% increase in subsequent cohorts depending upon toxicity.

Number of cycles: until progression or unacceptable toxicity develops.

Primary Outcome Measures :
  1. Number of patients with adverse events as a measure of safety and tolerability [ Time Frame: Cycle 1 (3 weeks), longer if DRC-MYC is continued; with 30 days follow-up after last dose ]

    Part A: 1 patient cohorts with 100% dose increase between cohorts until >/= Grade 2 study drug-related toxicity during Cycle 1, then expand to 3 patients and move to Part B.

    Part B: 3 patient cohorts with 50% dose increase between cohorts until study drug-related DLT during Cycle 1, then expand to 6 patients and move to Part C.

    Part C: 3 to 6 patient cohorts with 25% dose increase between cohorts until > 1 study drug-related DLT, then stop escalation and expand previous MTD cohort to 18 patients.

Secondary Outcome Measures :
  1. DCR-MYC levels in blood [ Time Frame: Cycle 1; Week 1 and Week 2 ]
    Samples to be collected Week 1 (Day 1, 2, and 4) and Week 2 (Day 8 and 11)

  2. DCR-MYC biological activities [ Time Frame: Cycle 1; Week 1 and Week 2 ]
    Collection of blood samples for cytokine measurements Week 1 (Day 1, 2, and 4) and Week 2 (Day 8)

  3. DCR-MYC biological activities [ Time Frame: Cycle 1, Cycle 2, and Cycle 4 ]
    PET imaging to be performed Cycle 1/Day 1, Cycle 1/Day 11, and End of Cycle 4

  4. DCR-MYC biological activities [ Time Frame: Cycle 1 and Cycle 2 ]
    Tumor biopsies (2 total) to be performed in MTD expansion cohort only. Patients will have biopsies performed prior to Cycle 1 and Cycle 2/Day 11

  5. Preliminary antitumor activity [ Time Frame: After Cycle 2 (6 weeks), then at 6 week intervals if DCR-MYC is continued ]
    Evaluation for evidence of objective response or disease stabilization
