Details and patient eligibility

About

This study is designed to evaluate the ability of intravenously (IV)administered 131-I-labeled TM-601 (chlorotoxin) to provide tumor-specific localization(via radiographic imaging) in patients with recurrent or refractory primary solid tumors with evidence of metastatic involvement. (Refractory tumors are non-responsive to standard treatment.) The safety and tolerability of IV administered 131-I-TM-601 in this patient population will be evaluated as part of this study.

Full description

This is a multi-center, open label, non-randomized, sequential, within-patient dose-escalation study in patients with recurrent or refractory primary solid tumors with metastatic involvement (including brain metastases). Patients will be administered 1 to 3 (Test Doses A, B and Dose C) escalating doses of 131-I-TM-601 by intravenous (IV) administration, with dosimetry (imaging-based evaluation of the dose reaching the target sites) conducted prior to and following administration of each dose. Whole body dosimetry on critical structures including, but not limited to, bone marrow, bladder, brain, liver, and thyroid will be determined. The preliminary results from Test Dose Levels (A and/or B) for each patient will be analyzed prior to treating patients with Dose C.

Patients will be followed until 28 days following the final dose, with a complete clinical assessment and imaging evaluations at the final follow-up visit.

Inclusion criteria

Histologically confirmed recurrent or refractory primary solid tumor malignancy. Primary tumor cell type is one of the following: breast, non-small cell lung, melanoma, colorectal, prostatic adenocarcinoma (hormone refractory) or glioma. Note: Patients with a primary solid tumor cell type not listed above, meeting all other selection criteria may be considered eligible, on a case by case basis
Demonstration of distant metastatic involvement as seen with standard clinical non-invasive imaging techniques (CT/MRI) or on biopsy. Note: on a case-by-case basis, patients with a locally recurrent, unresectable (inoperable) tumor may be considered for inclusion
Refractory to standard curative treatment
At least 18 years of age
Baseline Karnofsky Performance Status (KPS) of 60-100%
Life expectancy, based on investigator judgement, of greater than 3 months
Adequate organ and marrow function (as defined in protocol)
Women of child-bearing potential must have a negative pregnancy test, refrain from nursing, and must agree to use appropriate contraception for the duration of the trial

Exclusion criteria

Prior cytotoxic chemotherapy or radiotherapy within 4 weeks (6 weeks for nitrosoureas or mitomycin C) prior to entering the study
Patients who have not sufficiently recovered from adverse events due to previously administered agents
Concurrent treatment with investigational or commercial agents or therapies administered with the intent to treat the patient's malignancy, including chemotherapy, immunotherapy, biological response modifiers, or palliative radiotherapy. Possible exceptions (at the discretion of the investigator) are for hormonal therapy for breast and prostate cancer, hematologic, analgesic, biphosphonate, and any other form of supportive therapy.
History of allergic reactions attributed to compounds of similar chemical or biologic composition to 131-I-labeled chlorotoxin (e.g. iodine or iodine-containing drugs)
Patients with uncontrolled intercurrent illness.
