Treatment of Solid Tumors With Intratumoral Hiltonol® (Poly-ICLC) (Hiltonol)

December 21, 2017 updated by: Nina Bhardwaj

Treatment of Solid Tumors With Intratumoral Hiltonol® (Poly-ICLC): A Phase II Clinical Study

The purpose of this study is to test the safety of a course of injections containing Poly-ICLC in patients with advanced solid tumors that can be easily and safely reached with a needle.

Poly-ICLC is a compound that has been used to help the body in its fight against cancer.

Study Overview

Detailed Description

We hypothesize that this therapeutic in-situ autovaccination strategy is comprised of three immunomodulatory steps. The first is the innate immune local tumor killing induced by intratumoral Hiltonol (via NK, TNF, etc). A very close second step is optimal Th1-weighted priming through the in-situ combination of the poly-ICLC danger signal with the tumor antigens released in step 1 and further processed and cross-presented by poly-ICLC activated mDC, etc. The repeated administration of the Hiltonol danger signal IT in the context of the patient's own tumor antigens and in a way that mimics a natural viral infection may be critical to this step. Once the system is optimally primed, the third step is targeting and maintenance of the immune response and its facilitation at remote tumor sites with IM poly-ICLC through chemokine release, inflammasome activation and other costimulatory factors.

  • Interventional Model: Single Group Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: IT and IM injections Poly-ICLC
Enrolled patients will receive two cycles of Poly-ICLC treatment. Each priming (intratumoral injections - IT) and boosting (intramuscular injections - IM) treatment course will constitute one cycle.

Cycle 1-Weeks 1 and 2: 1mg Poly-ICLC intratumoral (IT) injections (t=6) into same lesion over 2 weeks.

Weeks 3-9: 1mg Poly-ICLC 2x/week intramuscularly (IM) into thighs or upper arms.

Week 10: No treatment. CT scan of chest, abdomen, pelvis and extremities or neck; possible MRI brain scan.

Cycle 2-Weeks 11 and 12: 1mg Poly-ICLC IT injections (t=6) into same lesion over 2 weeks.

Weeks 13-19 - 1mg Poly-ICLC 2x/weekly IM in thighs or upper arms.

Weeks 20-26: no treatment. Week 26, evaluate response in absence of inflammation.

Maintenance - Weeks 27-36: For patients with stable disease or response; IM poly-ICLC injections; evaluation of clinical and immune response. Week 38 repeat tumor assessment, optional biopsy

Follow Up via phone every 3 months for 30months, after completion of treatments.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Progression-free Survival
Time Frame: average 52 weeks

Progression-free survival defined as the time in weeks from study entry until tumor progression defined using the Wolchok criteria or death. Patients who are alive and free from progression on the date of closing follow-up will be censored on that date.

In order to minimize the potential for misdiagnosis of pseudoprogression, related to early inflammation, tumor measurement for determination of progression will be made at the earliest at 26 weeks.

average 52 weeks

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Therapeutic Effect in Treated Patients
Time Frame: 24 months
Induction of innate and/or an adaptive, specific anti-tumor T cell immune response in the injected tumor lesion and also systemically.
24 months

Other Outcome Measures

Outcome Measure
Measure Description
Time Frame
Overall Survival in Treated Patients
Time Frame: up to 30 months
Patients who are alive on the date of closing follow-up, or 30 months after completing all study treatments, will be censored on that date
up to 30 months
