Dose Escalation Study of I-131-CLR1404 in Subjects With Cancer That Does Not Respond to Treatment or Has Returned

Completed · Phase 1

Conditions studied: Cancer

In brief

The purpose of this study is to determine the recommended dose of I-131-CLR1404, a radiolabeled therapy compound, for treating subjects with cancer that does not respond to treatment or has returned. The identified recommended dose in this study will be used as the optimal dose of I-131-CLR1404 in subsequent clinical trials conducted for later phase clinical development. Subjects who meet study entry criteria will receive I-131-CLR1404. For each subject, the study will be conducted in two phases, dosimetric and therapy. In the dosimetric phase, subjects will receive one 5 mCi dose of the study drug and undergo whole body imaging on on the day of infusion and on post-infusion days 1, 2, 3, and 6 for assessment of biodistribution of I-131-CLR1404. If normal and expected biodistribution are demonstrated, the subject will begin the therapy phase. In the therapy phase, the first cohort of subjects will receive a dose of 12.5 mCi/m2. Dose escalation in subsequent cohorts will initially be in increments of 12.5 mCi/m2. Subjects will be followed and observed for unacceptable toxicity through 56 days after the therapy dose infusion with follow-up for up to one year. All subjects will be prescribed thyroid protection medication to be taken 24 hours prior to injection of the dosimetric dose, and continuing for 14 days after the administration of the therapy dose.

• Ambulatory w/ECOG performance status 0 to 2 and estimated life expectancy ≥ 4 mo.
• 18 years or older
• Judged by Investigator to have initiative and means to be compliant with protocol and w/n geographical proximity to make required study visits
• Ability to read, understand and provide written informed consent for initiation of any study related procedures (subject or legal representative)
• Brain metastasis acceptable if clinical condition stable ≥ 1 mo. Subjects with brain metastasis requiring steroids must have been on a stable or tapering dose of corticosteroids ≥ 1 mo. prior to enrollment
• Negative serum pregnancy test w/n 24 hours of enrollment (Female subjects of childbearing potential)
• Agreement to use effective contraception method (oral contraceptives, double-barrier methods, intrauterine device, Norplant, Depo-Provera) during study and 90 days following last dose

You may not qualify if…

• Subject or physician plans concomitant chemotherapy, therapeutic radiation and/or biological treatment for cancer including immunotherapy while on study. Localized palliative radiation therapy for bone pain allowed if clinically indicated. Ongoing hormonal therapy may be continued
• Received > 3 previous cytotoxic chemotherapy regimens
• Received > 25% of total bone marrow irradiated, total body or hemi-body irradiation or prior radioisotope therapy (except for benign thyroid disease)
• Diffuse lung disease or interstitial spread of carcinoma
• Prior radiation therapy or chemotherapy w/n 4 weeks of study start
• Extradural tumor in contact with spinal cord or tumor located where swelling in response to therapy may impinge upon spinal cord
• Other active medical condition or organ disease that may compromise safety or interfere with safety and/or outcome evaluation of study drug
• Laboratory abnormalities, including but not limited to: WBC < 3000/uL, Absolute neutrophil count < 1500/uL, Platelets < 150,000/uL, Hemoglobin ≤ 9.0 gm/dL, Total bilirubin > 1.5 x upper limit of normal for age, SGOT or SGPT > 3 x upper limit of normal for age if no liver metastases or > 5 x upper limit of normal for age in the presence of liver metastases, Serum creatinine > 1.5 x upper limit of normal for age, INR ≥ 2.0, 2+ proteinuria or casts indicative of intrinsic renal disease
