Trial Outcomes & Findings for ECI301 and Radiation for Advanced or Metastatic Cancer (NCT NCT01441115)

NCT ID: NCT01441115

Last Updated: 2021-12-28

Results Overview

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.

PRIMARY outcome

Timeframe: During treatment or the first three weeks after treatment

Population: 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.

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.

Outcome measures

Outcome data not reported

SECONDARY outcome

Timeframe: 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.

Population: 1/2 participants were analyzed because one participant was taken off study per Principal Investigator discretion and did not receive drug.

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

SECONDARY outcome

Timeframe: Before and after completion of ECI301

Population: This outcome measure was not done 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.

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.

SECONDARY outcome

Timeframe: Following the intravenous dose of ECI301

Population: This outcome measure was not done 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.

Pharmacologic parameters will be derived using non-compartmental analysis.

SECONDARY outcome

Timeframe: 6 months

Population: 1/2 participants were analyzed because one participant was taken off study per Principal Investigator discretion and did not receive drug.

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.

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.

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.
