Study Details

Study Description

Brief Summary

Background:
  • ECI301 is a drug that may help make cancer cells more visible to the immune system after radiation. The drug may also help the immune system destroy the cancer at sites that have not received radiation therapy. Researchers want to study ECI301 in people with advanced cancer or cancer that has spread in the body (metastatic).
Objectives:
  • To test ECI301 with radiation therapy for advanced or metastatic cancer.
Eligibility:
  • People at least 18 years of age with either metastatic or advanced cancer that may benefit from radiation therapy.
Design:
  • Participants will be screened with a medical history and physical exam. They will also have blood and urine tests, and imaging studies.

  • All participants will have radiation therapy 5 days a week for 2 weeks.

  • They will have different doses of ECI301 to test its safety and effectiveness. ECI301 will be given in a vein during the second week of radiation therapy. Frequent blood tests and imaging studies will monitor the treatment.

  • After participants have ECI301, tumor samples may be taken from the site that had radiation and another site that did not have radiation.

  • Follow-up visits will include blood tests and imaging studies.

Condition or Disease Intervention/Treatment Phase
Phase 1

Detailed Description

Background:
  • Patients with metastatic or locally advanced cancer frequently require palliative radiotherapy to relieve symptoms; however, progression of disease is frequent in patients with extended survival

  • Radiation results in tumor cell death which can result in increased dendritic cell activation and trafficking

  • ECI301 is a derivative of Macrophage Inflammatory Protein-1 alpha, a 70 amino acid chemokine that is a ligand for C-C chemokine receptor type 1 (CCR1) and C-C chemokine receptor type 5 (CCR5), the chemokine receptors of immature dendritic cells.

  • ECI301 has been shown to enhance the effect of radiotherapy in animal models.

Objectives:
  • The primary objective is to determine the maximum tolerated dose (MTD) of ECI301 delivered in combination with 30 Gray (Gy) of external beam radiation to patients with metastatic or locally advanced cancer.

  • The secondary objectives are:

  • To describe the safety and tolerability of ECI301 delivered in combination with 30 Gy of external beam radiation to patients with metastatic or locally advanced cancer

  • To evaluate the humoral and cellular immune responses by:

  • Measurement of circulating precursor dendritic cells before and after the completion of ECI301

  • Measurement of circulating MIP-alpha before and after the completion of ECI301

  • Assessment of T-lymphocyte quantitative and qualitative changes by flow cytometry and assays for interferon (IFN-gamma) production

  • To define pharmacologic parameters following the intravenous dose of ECI301

  • To determine if neutralizing anti-EC301 antibodies occur after treatment

  • To describe the response at the radiated site and distant sites after radiation in combination with ECI301

Eligibility:
  • Age >18 years.

  • Eastern Cooperative Oncology Group (ECOG) performance status <2.

  • Life expectancy of greater than 3 months

  • Histologically confirmed metastatic or locally advanced cancer for which radiotherapeutic management would be appropriate

  • No recent history of myocardial infarction or unstable angina

Design:
  • This is a Phase I trial to determine the maximum tolerated dose of ECI301 in combination with external beam radiation therapy in patients with locally advanced or metastatic solid tumors.

  • Patients will be treated with radiation therapy in a standard manner with ECI301 given daily during radiation. The dose of ECI301 will be escalated over the course of the trial to determine the maximum tolerated dose (MTD of daily ECI301 in combination with radiotherapy.

  • We anticipate that accrual to this trial of 30 patients will take approximately 2 years.

Outcome Measures

Primary Outcome Measures

  1. Maximum Tolerated Dose (MTD) of ECI301 Delivered in Combination With 30 Gray (Gy) External Beam Radiation to Participants With Metastatic or Locally Advanced Cancer [During treatment or the first three weeks after treatment]

    MTD is defined as the highest dose level at which no more than 1 of 6 participants experience dose-limiting toxicity (DLT) during treatment or the first three weeks after treatment, and the dose below that at which at least 2 (of ≤6) participants have DLT as a result of the drug. Examples of DLT is any grade 3 or greater non-hematologic toxicity, ang grade 3 neutropenia or thrombocytopenia, any grade 4 anemia, and toxicity requiring a cumulative radiation treatment delay of 4 or more days.

Secondary Outcome Measures

  1. Number of Adverse Events Unrelated, Unlikely, and Possibly Related to ECI301 Delivered in Combination With 30 Gray (Gy) of External Beam Radiation to Participants With Metastatic or Locally Advanced Cancer [Date treatment consent signed to date off study, and up to 30 days following the last dose of study drug, approximately 5 months and 25 days.]

    Adverse events were assessed by the Common Terminology Criteria for Adverse Events (CTCAE v4.0) and the Radiation Therapy Oncology Group (RTOG) criteria.

  2. Humoral and Cellular Immune Responses [Before and after completion of ECI301]

    Measurement of circulating precursor dendritic cells, circulating macrophage inflammatory protein-1 alpha (MIP-α), and assessment of T-lymphocytes will be measured by flow cytometry and assays for type II interferon (IFNγ) production.

  3. Pharmacologic Parameters Following the Intravenous Dose of ECI301 [Following the intravenous dose of ECI301]

    Pharmacologic parameters will be derived using non-compartmental analysis.

  4. Number of Participants With Response at the Radiated Site and Distant Site After Radiation in Combination With ECI301 [6 months]

    Response will be measured by the Response Evaluation Criteria in Solid Tumors (RECIST). Complete response is disappearance of all target lesions. Partial response is at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. Progressive disease is at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study. The appearance of one or more new lesions is also considered progression. Stable disease is neither sufficient shrinkage to qualify for partial response nor sufficient increase to qualify for progressive disease.

Other Outcome Measures

  1. Here is the Number of Participants With Non-Serious Adverse Events Assessed by the Common Terminology Criteria for Adverse Events (CTCAE v4.0) [Date treatment consent signed to date off study, and up to 30 days following the last dose of study drug, approximately 5 months and 25 days.]

    Here is the number of participants with non-serious adverse events assessed by the Common Terminology Criteria for Adverse Events (CTCAE v4.0). A non-serious adverse event is any untoward medical occurrence. A serious adverse event is an adverse event or suspected adverse reaction that results in death, a life-threatening adverse drug experience, hospitalization, disruption of the ability to conduct normal life functions, congenital anomaly/birth defect or important medical events that jeopardize the patient or subject and may require medical or surgical intervention to prevent one of the previous outcomes mentioned.

  2. Number of Participants With a Dose-Limiting Toxicity (DLT) [During treatment or the first three weeks after treatment]

    Examples of DLT is any grade 3 or greater non-hematologic toxicity, any grade 3 neutropenia or thrombocytopenia, any grade 4 anemia; nausea, vomiting, diarrhea, tumor pain, or pre-existing hyponatremia, dyselectrolytemia, or orthostatic hypotension that has been optimally treated with anti-emetics, anti-diarrheal, analgesics, or hydration and which persists for over 48 hours despite maximal medical therapy, and toxicity requiring a cumulative radiation treatment delay of 4 or more days.

2.1.1.7 Adequate marrow and organ function defined as

  • absolute neutrophil count (ANC) > 1.5 times 10(9)/L,

  • platelet count > 100 times 10(9),

Outcome Measure Data

Analysis Population Description
This MTD was not found because the trial was terminated early. A trial using ECI301 & radiation was initiated in Japan in 2012. This tested the primary endpoint in a duplicate trial, thus the study was closed. In addition, as specified in the protocol, the number of participants required to complete this trial involves 5 cohorts of 3 to 6 participants.
